High-risk pulmonary embolism (PE) is a complex clinical entity associated with high mortality rates. Ultrasound-assisted, catheter-directed thrombolysis, typically used for intermediate-risk PE, may be a viable treatment approach for high-risk PE, particularly in patients at increased risk for major bleeding. This report describes a case in which ultrasound-assisted, catheter-directed thrombolysis was successfully used to treat high-risk PE in a female patient with extensive peritoneal metastases from gastric adenocarcinoma. Other examples from the literature, in which ultrasound-assisted, catheter-directed thrombolysis was used to treat high-risk PE, are also provided.

Abstract Carpal tunnel syndrome (CTS) is the most common compressive neuropathy in the human body. Its symptoms result from compression of the median nerve in the carpus. The treatment can be conservative, with medications and/or infiltrations that alleviate the symptoms, or surgical, which is more effective, with decompression of the median nerve by surgical section of the flexor retinaculum of the carpus. The anesthetic technique varies according to the anesthesia method: sedation, venous locoregional anesthesia and, more recently, wide-awake local anesthesia no tourniquet (WALANT), which can be performed by the surgeons themselves. The WALANT technique uses local anesthesia with a vasoconstrictor, and does not require the use of a tourniquet on the upper limb nor sedation. The median nerve block in ultrasound-guided WALANT provides better accuracy to the technique, with greater patient safety; in the present article, its use in the performance of carpal tunnel decompression is described, and the literature is reviewed.

Objective: Point-of-care ultrasound (POCUS) is increasingly used to evaluate patients with musculoskeletal problems. Here we evaluated the impact of POCUS in musculoskeletal consultations in primary care setting using a Philips Lumify portable ultrasound device. We aimed to determine the impact of POCUS on the number of hospital referrals for therapeutic infiltrations as well as on the number of infiltrations performed in consultation. Design: This retrospective case study compared two periods: June to September 2021 (pre-POCUS) and November 2021 to February 2022 (POCUS). Statistical comparisons were performed using the chi-squared test. In both periods, 21 medical consultations were performed. In the pre-POCUS period, 470 patients were assessed, with average of 1.29 hospital referrals made per day for infiltration and average of 2.05 infiltrations performed per day during consultation. In the POCUS period, 589 patients were assessed, with an average of 0.1 hospital referrals per day (-92.6%; p

Intravenous cannulation is a common procedure for paramedics. Difficulty is often encountered and may result in escalation of care to an intensive care paramedic (ICP). Ultrasound-guided peripheral intravenous access (USGPIVA) is used in-hospital as an alternative approach. Historically limited to physicians, it is increasingly embraced by non-physicians, with point of care ultrasound (POCUS) devices more affordable, portable, and suited to the out of hospital environment. To explore the utility of ICP-performed USGPIVA for patients who are predicted to be difficult according to a difficult intravenous access scoring tool. This was a prospective observational pilot study of ICPs who used the adult difficult intravenous access (A-DIVA) scale to predict difficulty and perform USGPIVA using a contemporary POCUS device. For the 32 patients enroled, the overall success rate was 50% of which 87% were successful on the first attempt. Mean A-DIVA score was 4.1/5, and paradoxically, success improved with A-DIVA-predicted difficulty. ICPs can perform USGPIVA with moderate success. The A-DIVA score could be useful for paramedics to predict difficult cannulation. Future research should focus on increasing exposure, training time and enhancing feedback to paramedics performing USGPIVA. [ABSTRACT FROM AUTHOR]

Introduction: Previous studies have shown higher lumbar puncture (LP) success rates when using ultrasound guidance. This study aimed to compare the first-attempt success rate of ultrasound-guided LP with blind technique of needle insertion using the palpable spinal surface landmark in patients with obesity or a difficult anatomy. Methods: This prospective randomized controlled study was performed at the emergency department of Ramathibodi Hospital, an academic tertiary university hospital, from August 2015 to July 2016. Results: 40 patients were enrolled (20 surface landmark-guided and 20 ultrasound-guided LPs). 52.5% of the patients were male with the mean age of 60.33 ± 4.24 years. The first-attempt success rate in the ultrasound-guided LP group was significantly higher than the landmark-guided LP group (80% vs. 35%, respectively), with risk difference (RD) of 45.00% (95% confidence interval (CI): 17.72%, 72.28%). This indicated absolute risk reduction and number needed to treat of 45.00% and 2.22, respectively. The median procedural duration required to achieve successful LP in the ultrasound-guided LP group was significantly shorter than the surface landmark-guided LP group (5 [IQR: 3–18] minutes vs. 13.5 [IQR: 5-30] minutes, respectively). Traumatic puncture as a complication occurred less frequently in the ultrasound-guided LP group than the surface landmark-guided LP group with risk ratio (RR) = 0.33 (95% CI: 0.08, 1.46) and RD = -20.00% (95% CI: -44.00%, 4.00%). This indicated absolute risk reduction and number needed to harm of 20.00% and 5.00, respectively. However, the difference was not significant. Conclusion: Using ultrasound to help localize the insertion point before LP increased the first-attempt success rate and improved other LP outcomes in Thai patients with obesity or a difficult anatomy. It also shortened the procedural duration and reduced the incidence of traumatic tap.

Background: The authors aimed to compare the effects of a one-time ultrasound (US)-guided subacromial corticosteroid injection and three-time ozone (O2-O3) injection in patients with chronic supraspinatus tendinopathy. Methods: Participants were randomly assigned to the corticosteroid group (n = 22) or ozone group (n = 22). Injections in both groups were administered into subacromial bursa with an US-guided in-plane posterolateral approach. Primary outcome measure was the change in the Western Ontario Rotator Cuff Index (WORC) score between baseline and 12-weeks post-injection. Secondary outcome measures included visual analog scale and Shoulder Pain and Disability Index scores. Assessments were recorded at baseline, and 4-weeks and 12-weeks post-injection. Results: Forty participants completed this study. Based on repeated measurement analysis of variance, a significant effect of time was found for all outcome measures in both groups. Both the groups showed clinically significant improvements in shoulder pain, quality of life, and function. Baseline, 4-week post-injection, and 12-week post-injection WORC scores (mean ± standard deviation) were 57.91 ± 18.97, 39.10 ± 20.50 and 37.22 ± 27.31 in the corticosteroid group, respectively and 69.03 ± 15.89, 39.11 ± 24.36, and 32.26 ± 24.58 in the ozone group, respectively. However, no significant group × time interaction was identified regarding all outcome measures. Conclusions: Three-time ozone injection was not superior to a one-time corticosteroid injection in patients with chronic supraspinatus tendinopathy. It might be as effective as corticosteroid injection at 4-weeks and 12-weeks post-injection in terms of relieving pain and improving quality of life and function. [ABSTRACT FROM AUTHOR]

Background: Ultrasound-guided first sacral transforaminal epidural steroid injection (S1 TFESI) is a useful and easily applicable alternative to fluoroscopy or computed tomography (CT) in lumbosacral radiculopathy. When a needle approach is used, poor visualization of the needle tip reduces the accuracy of the procedure, increasing its difficulty. This study aimed to improve ultrasound-guided S1 TFESI by evaluating radiological S1 posterior foramen data obtained using three-dimensional CT (3D-CT). Methods: Axial 3D-CT images of the pelvis were retrospectively analyzed. The radiological measurements obtained from the images included 1st posterior sacral foramen depth (S1D, mm), 1st posterior sacral foramen width (S1W, mm), the angle of the 1st posterior sacral foramen (S1A, °), and 1st posterior sacral foramen distance (S1ds, mm). The relationship between the demographic factors and measured values were then analyzed. Results: A total of 632 patients (287 male and 345 female) were examined. The mean S1D values for males and females were 11.9 ± 1.9 mm and 10.6 ± 1.8 mm, respectively (P < 0.001); the mean S1A 28.2 ± 4.8° and 30.1 ± 4.9°, respectively (P < 0.001); and the mean S1ds, 24.1 ± 2.9 mm and 22.9 ± 2.6 mm, respectively (P < 0.001); however, the mean S1W values were not significantly different. Height was the only significant predictor of S1D (β = 0.318, P = 0.004). Conclusions: Ultrasound-guided S1 TFESI performance and safety may be improved with adjustment of needle insertion depth congruent with the patient’s height. [ABSTRACT FROM AUTHOR]

Objective: Body mass index is known to contribute to outcomes for patients with knee osteoarthritis. Furthermore, body mass index influences the protein expression of orthobiologic treatments like platelet-rich plasma and microfragmented adipose tissue. We performed a secondary analysis of the association of body mass index with patient-reported outcomes for patients with knee osteoarthritis who received either platelet-rich plasma or microfragmented adipose tissue injections., Methods: Seventy-one patients with knee osteoarthritis were randomized to receive a single ultrasound-guided injection of platelet-rich plasma or microfragmented adipose tissue. Platelet-rich plasma was created from 180 cc of anticoagulated blood and processed using a double-spin, buffy-coat concentration system. Microfragmented adipose tissue was created using autologous lipoaspirate that was processed according to minimal manipulation guidelines. Patient-reported outcomes and osteoarthritis outcome scores (Knee Osteoarthritis and injury Outcome Score) were tracked for 12 mos., Results: Forty-nine patients (platelet-rich plasma = 23, microfragmented adipose tissue = 26) completed 12-mo follow-up. Knee Osteoarthritis and injury Outcome Score quality of life and activity of daily living subscores were inversely correlated (both P < 0.05) with body mass index in the microfragmented adipose tissue but not platelet-rich plasmagroup. Knee Osteoarthritis and injury Outcome Score pain and sport subscores showed a trend toward inverse correlation with body mass index in the microfragmented adipose tissue group ( P = 0.07 and P = 0.06, respectively), but not platelet-rich plasma., Conclusions: Body mass index was negatively associated with patient-reported outcomes in patients who received microfragmented adipose tissue injections for knee osteoarthritis, but not for patients receiving platelet-rich plasma., Competing Interests: Financial disclosure statements have been obtained, and no conflicts of interest have been reported by the authors or by any individuals in control of the content of this article., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Peripheral nerve blocks effectively alleviate postoperative pain. Animal studies and human research suggest that opioid tolerance may reduce the effectiveness of local analgesics. The reduced effectiveness has been observed in opioid-tolerant humans and animals undergoing spinal and infiltration anaesthesia with both lidocaine and bupivacaine. However, the impact on peripheral nerve blocks in humans has not been evaluated. This study aims to assess the onset time and duration of a radial nerve block in opioid-tolerant individuals compared to opioid-naive individuals. We hypothesise that peripheral nerve blocks may be less effective in producing sensory and motor blockades in opioid-tolerant individuals compared to their opioid-naive counterparts., Methods: Twenty opioid-tolerant individuals will be matched by sex and age with opioid-naïve counterparts. Participants will receive an ultrasound-guided radial nerve block. The primary outcome is the difference in the duration of sensory nerve blockade between the two groups. The secondary outcomes include the onset time of sensory blockade, onset time of motor blockade, and difference in duration of motor nerve blockade., Conclusion: This study will compare the effectiveness of a peripheral nerve block between opioid-tolerant and opioid-naïve individuals. Any found differences could support a specific postoperative protocol for opioid-tolerant individuals regarding the use of peripheral nerve blocks., (© 2024 The Author(s).

Background: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is an alternative for biliary drainage in patients with obstructive pancreaticobiliary pathology when endoscopic retrograde cholangiopancreatography (ERCP) is not feasible. Despite its effectiveness, EUS-HGS is associated with a significant risk of adverse events. This study aimed to evaluate the feasibility and safety of a newly designed dedicated cautery-enhanced tubular self-expandable metal stent (SEMS) for EUS-HGS., Methods: This multicenter prospective study included patients with malignant biliary obstruction in whom ERCP had failed because of tumor infiltration, inability to drain the intrahepatic ducts, or surgically altered anatomy. A dedicated cautery-enhanced tubular SEMS was used for EUS-HGS. Technical and clinical success rates, procedure times, and adverse events were evaluated., Results: 20 patients underwent EUS-HGS with the dedicated stent. Technical and clinical success rates of 100% were achieved, with no reported severe adverse events or mortality. The median procedure time was 16 minutes. Recurrent biliary obstruction was observed in 1 patient., Conclusions: The dedicated cautery-enhanced tubular SEMS for EUS-HGS can simplify the procedure and enhance its safety and efficacy. This innovation shows promise for improving patient outcomes, although further studies are needed to validate these findings in a broader patient population., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Study Objective: Ultrasound-guided erector spinae plane block (ESPB) is commonly used for perioperative analgesia in adults; however, its analgesic efficacy and safety in pediatric patients remain uncertain. This review aimed to determine whether ultrasound-guided ESPB can improve analgesic efficacy and safety in pediatric surgery., Design: Meta-analysis of randomized controlled trials., Setting: Perioperative setting., Patients: Pediatric patients undergoing elective surgery under general anesthesia., Interventions: We searched PubMed, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, KoreaMed, Web of Science, Scopus, and ClinicalTrials.gov databases for eligible published randomized controlled studies (RCTs) comparing ESPB with controls (no block or other block) in pediatric patients undergoing elective surgery under general anesthesia., Measurements: The primary outcome was cumulative opioid consumption after surgery. Other outcomes included intraoperative opioid consumption, time to first request for rescue analgesia, number of patients requiring rescue analgesics, and pain scores after surgery. The safety outcomes were the incidences of bradycardia, hypotension, and postoperative vomiting., Main Results: The analysis included 17 RCTs comprising 919 participants: 461 in the ESPB group, 269 in the no-block group (no block/sham block), and 189 in the other block group. Compared with the control group (no block and other blocks), ESPB significantly reduced the cumulative opioid consumption (intravenous morphine milligram equivalents) after surgery (standardized mean difference = -1.51; 95% confidence interval, -2.39 to -0.64; P = 0.0002; I 2  = 92.9%) and intraoperative opioid consumption, and lowered average pain scores up to 24 h after surgery. ESPB extended the time to the first request for rescue analgesia and decreased the number of patients requiring rescue analgesics. Furthermore, ESPB lowered the pain score at most time points for 24 h after surgery, improved parental satisfaction, and reduced the incidence of postoperative vomiting compared with that in no block/sham block., Conclusions: ESPB provides effective and safe perioperative analgesia in pediatric patients undergoing elective surgery under general anesthesia., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Background: Endovascular aortic repair (EVAR) requires extensive preoperative, intraoperative, and postoperative imaging for planning, surveillance, and detection of endo-leaks. There have been manyadvancements in imaging modalities to achieve this purpose. This review discussed different imaging modalities used at different stages of treatment of complex EVAR., Methods: We conducted a literature review of all the imaging modalities utilized in EVAR by searching various databases., Results: Preoperative techniques include analysis of images obtained via modified central line using analysis software and intravascular ultrasound. Fusion imaging (FI), carbon dioxide (CO2) angiography, intravascular ultrasound, and Fiber Optic RealShape (FORS) technology have been crucial in obtaining real-time imaging for the detection of endo-leaks during operative procedures. Conventional imaging modalities like computed tomography (CT) angiography (CTA) and magnetic resonance (MR) angiography are still employed for postoperative surveillance along with computational fluid dynamics and contrast-enhanced ultrasound (CEUS). The advancements in artificial intelligence (AI) have been the breakthrough in developing robust imaging applications., Conclusions: This review explains the advantages, disadvantages, and side-effect profile of the abovementioned imaging modalities., (Copyright © 2024 Elsevier Inc.

Background: Hydrogels are used to provide a barrier against peritendinous adhesion formation, but when implanted intraoperatively, they degrade rapidly and aggravate early inflammatory pain. It is uncertain whether clinical efficacy can be improved by avoiding the inflammatory phase when hydrogels are delivered during adhesion formation., Questions/purposes: (1) Compared with intraoperative hydrogel application, does ultrasound-guided postoperative application result in better total active motion (TAM) at 12 months after tendon injury? (2) Does ultrasound-guided postoperative application of hydrogels result in lower pain, better function, and better satisfaction?, Methods: This open-label, prospective, single-center, randomized controlled trial was conducted by reparative and reconstructive surgeons at the National Orthopedics Clinical Medical Center, Shanghai, People's Republic of China. Between May 2021 and December 2022, 53% (168 of 317) of patients who met our inclusion criteria were recruited, and 47% (149 of 317) of patients were excluded because of the exclusion criteria. Finally, 84 patients were randomized to the postoperative group to receive ultrasound-guided carboxymethyl chitosan (CMC) hydrogel delayed injection, and 84 patients were randomized to the intraoperative group to receive CMC hydrogel intraoperative application. Another 8% (7 of 84) of patients in the postoperative group and 10% (8 of 84) of patients in the intraoperative group were lost before the minimum study follow-up time of 1 year or had incomplete datasets, leaving 91% (153 of 168) of patients with data for analysis. Data on outcome events were analyzed according to the intention-to-treat principle, which included all patients who underwent randomization. Follow-up visits were completed at 3 weeks, 6 weeks, 3 months, 6 months, and 12 months after tendon repair. The primary outcome was TAM (ie, the sum of the degrees of active metacarpophalangeal joint, proximal interphalangeal joint, and distal interphalangeal joint flexion less the degrees from full extension; minimum clinically important difference [MCID] 20°) at 12 months. Secondary outcomes included pain (measured with a VAS; range 0 to 10, a higher score indicating worse pain; MCID 0.6), Michigan Hand Outcomes Questionnaire activities of daily living (MHQ-ADL) score (range 0 to 100, a higher score indicating better outcomes; MCID 10.1), and MHQ satisfaction (MHQ-SAT) score (range 0 to 100, a higher score indicating better outcomes; MCID 33.0)., Results: At 12 months, the ultrasound-guided postoperative injection group had improved TAM (intraoperative 189° [95% CI 179° to 199°] versus postoperative 209° [95% CI 199° to 219°], mean difference 20° [95% CI 6° to 35°]; p = 0.006; the mean difference in the primary outcome fulfilled the MCID value at all time points). At 6 weeks, we found no clinically important difference in VAS pain scores among groups (intraoperative mean ± SD 2.0 ± 1.0 versus postoperative 1.7 ± 1.0, mean difference 0.3 [95% CI 0.1 to 0.7]; p = 0.02); however, at 3 weeks, the VAS pain scores showed clinically important difference among groups (3.6 ± 1.4 versus 2.9 ± 1.2, mean difference 0.7 [95% CI 0.3 to 1.1]; p = 0.001). At 3 months, the ultrasound-guided postoperative injection group had higher MHQ-ADL scores (intraoperative 62 ± 10 versus postoperative 75 ± 10, mean difference 13 [95% CI 11 to 17]; p < 0.001), and the mean difference of MHQ-ADL scores reached the MCID value at all time points. At 3 months, there was no clinically important difference in MHQ-SAT scores between groups (intraoperative 62 ± 8 versus postoperative 70 ± 8, mean difference 8 [95% CI 6 to 11]; p < 0.001)., Conclusion: Compared with intraoperative CMC hydrogel injection, postoperative ultrasound-guided injection improved the TAM and function of the affected limb, showed a short-term pain control effect, and did not increase the risk of complications. Clinical trials are needed to confirm the safety and efficacy of ultrasound-guided postoperative injection of CMC hydrogels and to determine the most effective dose and the health and economic benefits of treatment., Level of Evidence: Level I, therapeutic study., Competing Interests: Each author certifies that there are no funding or commercial associations (consultancies, stock ownership, equity interest, patent/licensing arrangements, etc.) that might pose a conflict of interest in connection with the submitted article related to the author or any immediate family members.

Background: To assess the safety and efficacy of ultrasound-assisted sagittal view for retrograde puncture of the P2 segment of popliteal artery (PA) for treating femoropopliteal lesions., Methods: A retrospective study was conducted on consecutive patients who underwent retrograde puncture of the PA for the recanalization of femoropopliteal lesions. A retrograde access was made to either the P2 or P3 segment of the PA in 23 cases. In 10 cases (8 men; mean age 68 ± 9 years), ultrasound-guided retrograde PA (P2 segment) puncture using the long-axis in-the-plane approach was performed, and in 13 cases (11 men; mean age 69 ± 5 years), angiography-guided retrograde PA (P3 segment) puncture was performed. Clinical data was compared preintraoperatively and postoperatively in the 2 groups., Results: All occluded lesions were successfully recanalized via dual channel intervention. Puncture success were 100% (10/10) in the P2 group compared with 92.3% (12/13) in the P3 group (P > 0.05). The mean puncture time in the P2 group was significantly shorter when compared to the P3 group (4.70 ± 0.95 mins vs 11.33 ± 6.37 mins; P < 0.05). There was no difference in mean hemostasis time between the 2 groups (6.11 ± 2.20 mins vs 8.46 ± 3.76 mins; P > 0.05). There were no in-hospital deaths in all patients. The occurrence of puncture-related complications in the P2 group was 10% compared with 15% in the P3 group (P > 0.05). A low-flow arteriovenous fistula was observed in one case in the P3 group. None of the patients reported any access-related complication at a mean follow-up of 11.3 ± 5.5 months., Conclusions: Ultrasound-assisted sagittal view for retrograde puncture of the P2 segment of PA is at least as safe as angiography-guided retrograde puncture of the P3 segment for femoropopliteal lesions. Furthermore, this technique appears to be more suitable for patients with tandem iliofemoral artery occlusion, as it allows for the creation of a retrograde access., (Copyright © 2024 Elsevier Inc.

The rate of refractory chronic pain after total knee replacement (TKR) is 20-25%, with no identifiable etiology in 6% of cases. Without an etiologic diagnosis, the surgeon is unlikely to consider revision, but pain poses a therapeutic challenge for achieving satisfaction and an acceptable quality of life. Genicular nerve radiofrequency ablation (GNRFA) was recently developed as a non-drug analgesic option. It is minimally invasive and safe, with few adverse effects, opening a new perspective for management of refractory chronic pain after TKR. LEVEL OF EVIDENCE: IV., (Copyright © 2024.

Background: To present the value of intravascular ultrasound (IVUS) in diagnosis and treatment of complicated type B aortic dissection with malperfusion. Especially, the value of IVUS regarding the treatment strategy, reoperation rate, acute kidney injury, and false lumen thrombosis was investigated., Methods: Retrospective analysis of 25 type B aortic dissection cases with malperfusion treated with endovascular therapy from April 2019 to August 2022. In 17 cases, angiography and IVUS were applied during the operation (IVUS group), and in 8 cases, angiography was used without IVUS (control group) for final intraoperative control. IVUS was used to assess the true lumen collapse and to decide if additional bare stenting was necessary or not. Details from patients' charts and documentation from surgeries were analyzed. The endovascular technique included thoracic endovascular aortic repair with primary entry sealing and-if needed-bare stenting of the true lumen distal of the entry tears using the Provisional Extension To Induce Complete Attachment (PETTICOAT) technique., Results: All patients presented with pain localized mostly (48%) in thorax and abdomen. In all patients, the proximal entry tear of the dissection was covered using thoracic endovascular aortic repair. The PETTICOAT technique was applied in 13 cases (52%), whereas most combined procedures were applied in the IVUS group (12 compared to 1; P = 0.02). A total of 3 patients (1 in the control group, 12.5% and 2 in the IVUS group, 11.8%) underwent a bowel resection. Totally 8 patients (32%) underwent a reoperation in aorta (3 during the hospital stay). There were no statistical differences between IVUS and control group regarding the preoperative findings, the reoperation rates, and the postoperative complications. Five patients died (4 during the hospital stay); 1 in control and 4 in IVUS group; P = 0.53. The follow-up included a clinical and a computed tomography angiography examination. No statistically significant difference regarding occurrence and extension of false lumen thrombosis was observed between the 2 groups., Conclusions: The IVUS and control groups showed no difference in survival rates. The use of IVUS extended the indication for PETTICOAT technique with statistically significant difference. A milder form of acute kidney injury presented in the IVUS group compared to the control group. In addition, a stronger correlation between IVUS and the avoidance of an aorta reoperation was observed, although it did not reach statistical significance., (Copyright © 2024 The Author(s).

Vascular access for hemodialysis is the lifeline for patients with end-stage renal disease (ESRD); therefore, maintenance of the vascular access is of the utmost importance. The dialysis circuit can be complicated by stenosis or thrombosis. In particular, central venous stenosis is frequently encountered in the vascular access of patients with ESRD, and this complication may require endovascular management. Conventional catheter-based venography may be inadequate for identifying dynamic forms of extrinsic compression and intravascular webs associated with these lesions. For these types of access complications, balloon angioplasty remains the first-line intervention, with stenting reserved for selected scenarios. Accurate assessment of the venous configuration is therefore important to ensure an adequate treatment response. Intravascular ultrasound (IVUS) has been shown to be beneficial in lower extremity venous interventions. The use of IVUS in dialysis access interventions is currently limited but may be indicated in selected challenging clinical situations. In this article, we discuss the potential uses of IVUS in the ESRD population based on our institutional experience and on the current literature., (Copyright © 2024 Elsevier Inc.

Objective: Venous stents are a common treatment modality for obstructive venous disease. Venous stents differentiate themselves by either a woven or braided structure, open or closed cell arrangement or based on material composition (elgiloy vs nitinol). Changes in the morphology of venous stents over time may contribute to restenosis or thrombosis. Woven elgiloy stents are prone to proximal and distal edge deformation compared with dedicated venous stents, which offer increased radial force at stent edges. The objective of this study is to describe luminal morphological changes among various venous stents and between woven to nonwoven venous stent configuration, over time., Methods: A retrospective review at a single institution between January 2014 and June 2021 identified patients treated with venous stents. Patients with iliac and/or femoral venous stents with intraoperative intravascular ultrasound and a postoperative computed tomography scan were included in the study. Cross-sectional diameters measurements were taken at proximal, middle, and distal portions of each stent from intravascular ultrasound examination at the time of initial stenting and compared with the cross-sectional diameter measurements taken from computed tomography imaging at follow-up. A paired t test was used to compare the luminal change with a D'Agostino-Pearson test used for normality., Results: Fifty-four stents distributed among 38 patients were identified. The mean time to follow-up was 17.5 months. Stents were placed in the common iliac vein (n = 37, 68.5%), external iliac vein (n = 14, 25.9%), and common femoral vein (n = 3, 5.6%). Implanted stents included the Boston Scientific Wallstent (n = 23, 42.6%), Bard Venovo (n = 3, 5.6%), Boston Scientific Vici (n = 23, 42.6%), and Medtronic Abre (n = 5, 9.3%). The mean luminal loss was measured at 2.12 mm proximally (95% confidence interval [CI], 1.64-2.60; P<.001), 1.29 mm at the mid-stent (95% CI, 0.83-1.74, P<.001), and 1.56 mm distally (95% CI, 0.99-2.12; P<.001). There was no significant difference in luminal changes between woven and nonwoven stents at proximal (P = .374), middle (P = .179), and distal (P = .609) stent measurements., Conclusions: This study reports morphological changes within venous stents and between woven and nonwoven venous stents. Our findings demonstrate that the edge-stent luminal decrease traditionally attributed to woven configurations also occurs with the newer nonwoven stents. Additional factors such as anatomical location, pelvic curvature, and other external forces may be accountable for this change rather than geometrical configuration of the stent., Competing Interests: Disclosures None., (Copyright © 2024 The Author(s).

To assess outcomes of supracostal ultrasound guided approach percutaneous nephrolithotomy (SUGA-PNL) and retrograde intrarenal surgery (RIRS) in isolated large volume upper calyceal stones (UCS). This was a prospective randomized study including patients with isolated UCS > 20mm. The patients were randomized into two groups: group (P) (SUGA-PNL) and group (R) (RIRS). Patients' demographics, stones characteristics, operative, and postoperative outcomes essentially the stone free rate (SFR) and complications rate were documented. The stone clearance was defined as no fragments or residual fragments less than 2mm in the one month non contrast CT scan follow up. Eighty-nine patients opted to undergo the procedure according to the preoperative randomization. Four patients, 2 patients from each group, lost to follow up and other 2 patients were excluded from group (R) due to a tight ureter. Both groups were comparable as regards the preoperative demographics and stone characteristics. There were statistically significant differences regarding total operative time, the change in hemoglobin level, and postoperative pain score (P: 0.024, 0.010 and 0.032 respectively). The SFR was 88.1% in group (P) compared to 73.2% in group (R) (P: 0.019). Moreover, it did not differ significantly between both groups regarding the intraoperative and postoperative complications. No visceral and thoracic injuries were documented in group (P). On other side, 6 patients (14.6%) from group (R) had different grades of ureteral injury during access sheath placement. SUGA-PNL is a safe and effective treatment modality for UCS > 20mm with a higher SFR than RIRS., (© 2024. The Author(s).)

Background: Various devices and techniques have been used for plaque modification in the treatment of severe coronary artery calcification. This prospective, multicenter, randomized, open-label study aims to evaluate the safety and efficacy of cutting balloon angioplasty using a novel bioabsorbable polymer-coated everolimus-eluting coronary stent for treating various degrees of calcified coronary lesions., Methods: We outline the trial design aimed at assessing whether the cutting balloon (Wolverine™) is non-inferior to the non-compliant balloon in treating patients with calcified lesions, encompassing both de novo and in-stent restenosis (ISR) lesions. We aim to enroll 250 patients who have undergone bioabsorbable polymer-coated everolimus-eluting coronary stent (Synergy™) implantation. The primary endpoint is the minimal stent cross-sectional area at the calcium site as determined by intravascular ultrasonography. The secondary endpoints include major adverse cardiac events and target lesion revascularization at 12 months, alongside procedural convenience and operator-centric parameters, such as the number of balloons used, procedure time, and total contrast medium volume used., Discussion: In this study, we will evaluate the efficacy and safety of Wolverine™ and non-compliant balloon in patients with calcified coronary lesions and provide a rationale for which type of balloons will optimally modify calcium lesions. In addition, we will attempt to expand the indications of the cutting balloon for treating mild-to-severe calcified coronary lesions. As the scope of insurance coverage for cutting balloons remains limited in some countries, this study may provide evidence for extending insurance coverage to the treatment of de novo calcified and ISR lesions., Trial Registration: ClinicalTrials.gov NCT06177808.

Background: This pilot prospective study aimed to evaluate ultrasound-guided cryoablation of breast cancer (BC) by assessing: (i) technical efficacy as the presence of necrosis in surgical specimens and rate of complete tumor ablation; (ii) safety as incidence and severity of complications; and (iii) patients' satisfaction using a dedicated questionnaire. In addition, (iv) we tested the capability of magnetic resonance imaging (MRI) or contrast-enhanced mammography (CEM) to predict cryoablation efficacy., Methods: From 07/2022 to 01/2023, we enrolled 20 patients with early-stage BC scheduled for breast surgery. Ten of them, with a cryo-feasible cancer location, were sent to cryoablation (cryo-group) and ten to routine surgical practice (control group). Both groups underwent surgery and were asked to answer a satisfaction questionnaire., Results: Of eleven patients screened for cryoablation, only one refused to be treated at another hospital (acceptance rate 10/11, 91%). Surgery was quadrantectomy in 19 cases and mastectomy in 1. In the cryo-group, the procedure was completed and steatonecrosis was observed in 10/10 cases, with complete tumor ablation in nine of them. The post-procedural status was evaluated with MRI in five patients, with CEM in four patients, and with ultrasound in one patient who refused MRI and CEM. MRI or CEM correctly predicted complete cryoablation in eight patients and incomplete cryoablation in one patient. Patients in both groups did not have serious complications and responded positively to satisfaction questionnaires., Conclusion: Ultrasound-guided cryoablation of early-stage BC is well accepted by patients, effective, and safe. MRI and CEM were able to predict the procedure's technical efficacy., Trial Registration: https://clinicaltrials.gov/study/NCT05727813 updated February 14, 2023., Relevance Statement: Our pilot study showed that ultrasound-guided cryoablation is a promising nonsurgical alternative for treating early-stage BC., Key Points: Ultrasound-guided cryoablation was effective and safe in early BC patients. The procedure was well-tolerated, with low morbidity and high patient satisfaction. MRI and CEM predicted cryoablation efficacy, in accordance with histopathologic findings. Cryoablation can be considered a potential alternative to surgery in selected patients., (© 2024. The Author(s).)

Objective: To compare the postoperative analgesic efficacy of ultrasound-guided infraspinatus-teres minor interfascial block and interscalene block in shoulder arthroscopic surgery. Methods: A total of 74 patients undergoing shoulder arthroscopic surgery at the Affiliated Hospital of Jiaxing University from December 2023 to February 2024 were prospectively included, whose age ranged from 18 to 80 years and the American Society of Anesthesiologists (ASA) grade were Ⅰ-Ⅲ. Patients were divided into two groups using block randomization: infraspinatus-teres minor interfascial block group (observation group) and interscalene block group (control group), with 37 cases in each group. In the anesthesia preparation room, all patients received nerve blocks under ultrasound guidance with 20 ml of 0.375% ropivacaine. Patient-controlled intravenous analgesia (PCIA) was administered to all patients following surgery. The primary outcome was the area under the curve (AUC) of the numeric rating scale (NRS) for pain within 24 hours postoperatively. Secondary outcome measures included the highest NRS score within 48 hours postoperatively, the amount of sufentanil used via PCIA within 48 hours postoperatively, the incidence of rescue analgesia and rebound pain, QoR-40 scores, and the rate of postoperative nausea and vomiting within 24 hours. The non-inferiority margin for the AUC of NRS scores between the two types of regional nerve blocks was set at "2.6". Results: A total of 35 patients were included in the observation group [17 males, 18 females, aged (58.1±9.1) years], and 36 patients were included in the control group [12 males, 24 females, aged (57.0±9.8) years]. The AUC of the NRS scores at rest within 24 hours post-operation was 51.7±10.9 in the observation group and 62.6±13.6 in the control group. The difference in AUC between the two groups was -10.9 (95% CI :-16.8--5.1), with the upper limit of the 95% CI falling below the predefined non-inferiority margin of "2.6" (non-inferiority P <0.001). The highest NRS score [ M ( Q 1 , Q 3 )] within 48 hours post-surgery was 3 (3, 4) in the control group, which was significantly higher than the observation group's score of 2 (2, 3) ( P <0.001). During the postoperative period of 0-12 hours, the observation group received a median dose of 12 (10, 14) μg of sufentanil, which was significantly higher than the control group's dose of 8 (6, 10) μg ( P <0.001). During the postoperative period of 12-24 hours, the observation group received a median dose of 8 (8, 10) μg of sufentanil, which was significantly lower than the control group's median dose of 12 (10, 14) μg ( P <0.001). During the postoperative period of 24-48 hours, there was no statistically significant difference in the dose of sufentanil between the two groups of patients ( P =0.548). In the observation group, the incidence of rescue analgesia within 48 hours postoperatively was 0 (0/35), which was lower than that of the control group at 22.2% (8/36) ( P =0.010). The occurrence of rebound pain in the observation group was 0 (0/35), and the control group was 11.1% (4/36), no statistically significant difference was found between two groups ( P =0.130). In the observation group, the QoR-40 score within 24 hours post-operation was 180.2±3.2, which was higher than the control group's score of 175.8±4.7 ( P <0.001). There was no statistically significant difference in the incidence of postoperative nausea and vomiting within 24 hours between the two groups ( P =0.372). Conclusion: Ultrasound-guided infraspinatus-teres minor interfascial block demonstrates a comparable analgesic effect to interscalene block in shoulder arthroscopic surgery within the first 24 hours postoperatively.

Introduction: Prompt resolution of arteriovenous fistula (AVF) thrombosis is essential to minimize the need for temporary dialysis catheters. Identifying the ideal timing for the management of thrombosed arteriovenous fistula (AVF) is an area that has not been thoroughly explored. Herein, we examined a local infusion of urokinase for thrombolysis followed by ultrasound-guided percutaneous transluminal balloon angioplasty (PTA) in acute and subacute AVF thromboses., Methods: This retrospective cohort research assessed thrombosed AVF in patients referred to the Second Xiangya Hospital. We included patients who underwent local thrombolysis followed by ultrasound-guided PTA treatment between January 1, 2018, and January 1, 2020.  Results. We enrolled the records of 86 patients into the present study, including 44 patients with acute AVF thrombosis (group 1: thrombus age, < 72 hours) and 42 patients with subacute AVF thrombosis (group2: thrombus age, 72 hours to seven days). The thrombolytic success rate was 79.5% in group 1 and 42.9% in group 2 (P < .001). All patients underwent ultrasound-guided PTA to dissolve any residual thrombi regardless of thrombolytic success. Technical success after PTA procedures was achieved in 93.2% of patients in group 1 and 88.1% in group 2 (P = .417). Primary patency at six months was comparable between the two groups (67.5% vs. 64.8%, P = .564). We observed that thrombolytic effect does not affect PTA success rate, and six-month patency rate., Conclusion: Direct local infusion of urokinase to the affected area followed by ultrasound-guided PTA constitutes a minimally invasive and effective method for salvaging thrombosed AVF in contrast to abandoning the occluded fistula.

Background: Intramuscular fat grafting in extremity muscles, especially the gastrocnemius, has become increasingly popular. However, while safety in truncal muscle fat grafting has been well-studied, research on extremity muscles is lacking., Objectives: In this study, we aimed to explore the anatomy of the gastrocnemius muscle and adjacent structures as intramuscular and subcutaneous recipient sites. Additionally, we sought to analyze pressure-volume relationships and fat migration patterns during posterior calf grafting., Methods: Eight cadaveric lower extremities were examined. A prosection was performed to better understand the vascular complex around the gastrocnemius. Ultrasound-guided fat injections were then performed into both the subcutaneous and intramuscular layers; dynamic pressures were measured with a manometer. Last, dyed-injectant was injected subcutaneously to better elucidate subcutaneous anatomy., Results: Anatomic prosection demonstrated the proximity of the gastrocnemius muscle to the popliteal venous system that arborized (>1 mm) intramuscularly. In the 3 specimens that underwent intramuscular fat grafting, the peak intramuscular pressures plateaued at 21 mmHg (19.5-23 mmHg); there was no observed extrafascial migration of the injectant. With subcutaneous injectant in 1 specimen, pressures in the subcutaneous space increased (125 mmHg) with additional injectant (240 mL) while pressures in the intramuscular space remained relatively constant (4 mmHg)., Conclusions: Intramuscular gastrocnemius fat grafting should be done with caution: its proximity to critical veins and sustained increased intramuscular pressures following grafting increases risks of embolus and thrombosis, respectively. Subcutaneous injection may be safer in that increased pressures are not communicated to deep structures. Last, we present a novel description of posterior calf subcutaneous compartments that may better allow surgeons to direct and predict subcutaneous injectant., (© The Author(s) 2024.

Background: Treating an underactive bladder (UAB) is challenging. Previously, we introduced a more precise method of transvaginal ultrasound-guided botulinum toxin A (BoNT-A) injection into the external urethral sphincter as a treatment option for patients with UABs. Although many patients experience good results, those with an UAB and excessive residual urine still require catheterization. Therefore, we developed a new method that combines transvaginal ultrasound-guided BoNT-A injection with a transurethral bladder neck incision. Methods: A prospective study was conducted on 16 patients who experienced symptoms of UAB and chronic urine retention. The treatment consisted of a combination of transvaginal ultrasound-guided BoNT-A injection and a transurethral incision of the bladder neck (TUI-BN). The primary objective was to assess the efficacy of this combined treatment in improving symptoms in women with UABs. Results: Our study demonstrated significant improvements after treatment, including increased voiding volume, decreased post-void residual (PVR) urine, and improved voiding efficiency. The frequency of clean intermittent catheterization (CIC) decreased at 1 and 3 months post-surgery, along with improvements in the AUA symptoms score and the Patient Perception of Bladder Condition (PPBC) score. Conclusions: Our study showed significant improvements in the surgical treatment of UABs using a combination of transvaginal ultrasound-guided BoNT-A and TUI-BN.

Background: Celiac plexus block has been commonly utilized for the treatment of chronic pancreatitis-associated abdominal pain. Prospective studies suggest efficacy in 30 to 50% of patients, although no randomized sham-controlled trials have been performed. The objective of this study is to assess the effect of endoscopic ultrasound (EUS)-guided celiac plexus block on abdominal pain in patients with documented chronic pancreatitis., Methods: This is a two-arm randomized sham-controlled trial with blinded evaluators. The study will be conducted at multiple academic sites in the United States who are members of the United States Pancreatic Disease Study Group (USPG). Patients referred for EUS to exclude chronic pancreatitis as a cause of abdominal pain as well as those with established painful chronic pancreatitis undergoing EUS for another indication will be eligible. At the time of EUS with confirmation of chronic pancreatitis by standard EUS diagnostic criteria, patients will be randomized to either celiac plexus block or sham whereby an anesthetic and steroid combination will be injected into the celiac plexus or saline will be injected into the gastric lumen with the same type of needle as used for celiac plexus block, respectively. The main outcome measure will be a 50% reduction in abdominal pain using the Brief Pain Inventory Short Form (BPI-SF) at 1 month post-intervention. A number of secondary outcomes will be measured including visual analog scale (VAS), Comprehensive Pain Assessment Tool Short Form (COMPAT-SF) pain scores, and quality of life using a pancreas-specific validated measure (PANQOLI)., Discussion: In this study, the effect of celiac plexus block on abdominal pain in patients with chronic pancreatitis will be compared to a sham intervention. This randomized trial will offer a definitive assessment of the role of celiac plexus block for the treatment of abdominal pain in this setting.

Background: Percutaneous vertebroplasty or kyphoplasty is the preferred procedure for stage I and II Kümmell's diseases (KDs), but there exist controversies on the operative option of stage III KD. This study aimed at exploring the safety and efficacy of ultrasonography-guided canal decompression (UG-CD) combined with vertebroplasty and cement-augmented pedicle screw fixation (CA-PSF) for treating stage III KD with neurological deficit (ND)., Methods: Between September 2017 and December 2023, all patients who received the UG-CD combined with vertebroplasty and CA-PSF for managing stage III KD with NDs were reviewed retrospectively with their demographic and operation data, and complications recorded. Besides, the scores of Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI), together with imaging data including the kyphotic Cobb angle (KCA), wedge angle (WA), spinal canal area (SCA) at the narrowest level as well as anterior (AHR) and middle (MHR) height ratios were measured and compared between pre- and post-operation., Results: A total of eleven patients with a mean age of 70.09 ± 2.98 years old were included in our study with their surgical time, hospitalization length, blood loss, and follow-up time being 150.91 ± 17.94 min, 202.09 ± 39.95 ml, 8.18 ± 1.17 days, and 16.91 ± 4.09 months, respectively. During the final follow-up, the KCA, WA, VAS scores, ODI scores, AHR, MHR, and SCA were significantly improved (P < 0.01). Intraoperatively, one case suffered a transient decrease in the motor evoked potential. Another case experienced a cerebrospinal fluid leakage postoperatively that was then successfully treated., Conclusion: UG-CD combined with vertebroplasty and CA-PSF could be a feasible procedure for safely and effectively handling stage III KD with NDs., (© 2024.

Purpose: The primary outcome of this study is to compare the success rates of ONB techniques performed either with ultrasound guidance or with the blind technique. The second outcome is to compare the incidences of perioperative bleeding and the presence of recurrent tumors in the control cystoscopy performed in the 3rd postoperative month in both groups., Materials and Methods: The study was conducted in the urology operating room of Mugla Sitki Kocman Training and Research Hospital between December 2019 and March 2023. A total of 122 patients were included in the study: 22 females with a mean age of 56.63 ± 12.99 years and 100 males with a mean age of 63.18 ± 8.00 years. In one group (group 1), ONB was performed under ultrasound guidance by the same anesthesiologist, and in another group (group 2), ONB was performed blindly based on anatomical signs by the same urologist., Results: Adductor muscle contraction was not observed in 53 patients (91.4%) in group 1 and in 49 patients (76.6%) in group 2 (p = 0.027)., Conclusion: The success rate of ONB was higher when using an ultrasound-guided technique than when using a blind technique.

Background: Cervical dystonia is widely understood to benefit from botulinum toxin injections. The injection practices may be influenced by specific factors, including the method of injection. Three main guidance methods can be used: palpation of anatomical landmarks, ultrasound, and electromyography. We investigated how target muscles and doses of botulinum toxin were modified after the transition from surface anatomy (non-guided) to ultrasound (US-guided), in patients with cervical dystonia. We also determined the long-term dose trend., Methods: We studied a group of 82 patients, who received non-guided injections (median: 16.5 cycles/5.1 years) followed by US-guided injections (median: 12.0 cycles/3.8 years)., Results: More muscles, and especially deep muscles, were injected during the US-guided period. The total dose and number of injected muscles were higher when US guidance was used, but the mean dose per muscle was lower. Over the long term, the total dose stabilized, and the mean dose per muscle decreased during the US-guided period., Conclusions: According to our results, the guidance method has a strong impact on the botulinum toxin injection strategy in cervical dystonia (target muscles and dose). Also, the treatment appeared more stable when using US guidance; this could be explained by the good precision of such injections.

Background: One key focus of partial nephrectomy is preserving renal function. Segmental renal artery occlusion with microdissection at the renal hilum confines ischemia, effectively reducing warm ischemic injury. Ultrasound-Guided Renal Artery Balloon Catheter Occluded Hybrid Partial Nephrectomy (UBo-HPN) can achieve branch occlusion without the need for dissecting the renal hilum., Objective: To investigate the feasibility and safety of UBo-HPN of branch renal artery occlusion in the treatment of localized renal tumors., Subject and Methods: A prospective single-arm analysis involving 20 patients with renal localized tumors underwent robot assisted UBo-HPN with branch renal artery occlusion from August 2021 to July 2023, with an average follow-up of 12 months., Results: All patient was successfully operated on without conversion to conventional arterial clamping or radical nephrectomy. One case (5%) of minor complication occurred in the whole cohort, which was bruising around the puncture site. The mean total operative time was 95.8 min, with a mean operative time of 21.25 min for vascular intervention. The mean warm ischemia time was 20.35 min, and the median estimated blood loss was 50 ml. The median eGFR preservation percentage at postoperative 48 h, 30 days, and the latest follow-up were 87.52%, 91.47%, and 92.2%, respectively. After a median follow-up of 10.2 (2.3-19.2) months, no patients had radiological tumor recurrence or died from tumor-related causes., Conclusions: UBo-HPN with renal artery branch occlusion emerges as an efficient alternative to partial nephrectomy (PN), which achieved branch artery occlusion without dissecting the renal hilum. Long-term follow-up is expected for functional outcomes., (© 2024. The Author(s).)

Background: An atrial septal defect (ASD) is considered oval-shaped when its shortest diameter is less than 75% of the longest diameter. Research on percutaneous closure of oval-shaped ASDs is limited, with no known reports of non-fluoroscopic closure for this population., Objective: To assess the effectiveness of non-fluoroscopic percutaneous closure for oval-shaped ASDs., Methods: This single-center retrospective study evaluates patients undergoing non-fluoroscopic percutaneous closure of oval-shaped ASDs, defined by the shortest to longest diameter ratio < 0.75, a circular index of 1.33, or ultrasound visualization of an oval shape. Device size was chosen to be 0-4 mm larger than the defect's longest diameter, based on transthoracic and transesophageal ultrasound measurements., Results: We identified 78 patients (33.3% children, 20.5% males) with a mean age of 27.4 ± 16.3 years and a mean weight of 46.8 ± 19.8 kg. The mean longest diameter and mean shortest diameter of ASDs were 23.3 ± 6.8 mm and 15.8 ± 5 mm, respectively. The mean ratio of the shortest to longest diameter was 0.7 ± 0.1. Percutaneous closure was not attempted in 7/78 (9%) patients. Three out of 71 (4.2%) procedures were fluoroscopy-guided upfront due to technical difficulties, and 5/71 (7%) were converted to fluoroscopy-guided closure. Overall procedural success rate was 98.6% (70/71) including 63/71 (88.7%) performed with zero fluoroscopy. Mean device size was 26.5 ± 7.1 mm. Mean procedural time was 45.3 ± 22.6 min. Eleven intraprocedural complications occurred including 6 arrhythmias, 3 pericardial effusions, and 2 device dislodgements., Conclusion: Transcatheter closure of oval-shaped ASD is safe and feasible. Echocardiography is adequate for adequate operative guidance., (© 2024. The Author(s).)

Ultrasound-guided cannulation (USGC) of a peripheral vein reduces the need for central vascular access device (CVAD) placement to perform a successful apheresis procedure. Effective training of healthcare professionals to acquire this skill is essential. Here, we report on the implementation of the USGC training across eight apheresis units in England. A 3-h introductory training program was devised with theoretical and practical elements. This was followed by supervised USGC practices on any patient ≥ 18 years old, regardless of venous status. Data on all supervised USGC attempts were recorded and analyzed. Over an 11-month period, 11 nurses were trained to USGC competency with another six nurses still in training, resulting in seven out of eight units having at least one USGC-competent nurse. In one unit, USGC training has not started yet. Three hundred sixty-one supervised USGC episodes on 168 patients and donors took place; of these, 178 were done for training purposes only on patients who had visible and palpable veins, 179 USGC were done on patients with difficult venous status and four were not recorded. The period from first supervised USGC to competency was a median of 45 days (Range: 17-166 days), with a median of 15 successful (Range: 10-30) and two unsuccessful (Range: 1-15) USGC being performed per trainee. The placement of 57 CVADs and 41 multiple cannulation attempts have been avoided. USGC is a useful tool to reduce the need for CVAD. Training across multiple apheresis units is a lengthy procedure, but it can be successfully implemented., (© 2024 Wiley Periodicals LLC.)

Peripheral neuropathy is a common complication in patients with diabetes. However, the appropriateness of administering nerve block anesthesia to these patients remains uncertain. Key concerns include the potential for prolonged block duration, an increased risk of local anesthetic toxicity, and the possibility of further damaging already compromised peripheral nerves. We herein report a case involving a patient with diabetic peripheral neuropathy who underwent finger amputation under ultrasound-guided nerve block anesthesia and subsequently lost pain and temperature sensation in both hands 1 month later. For critically ill patients undergoing surgery, regional anesthesia, such as a nerve block, may be a more suitable option than general anesthesia. When performing nerve block procedures in patients with diabetes, using ultrasound guidance is recommended to ensure precise targeting and reduce the risk of complications. However, it remains unclear whether nerve block anesthesia exacerbates peripheral neuropathy., Competing Interests: Declaration of conflicting interestsThe authors have no conflicts of interest to declare.

Purpose: Previous research has demonstrated that real-time ultrasound-guided (UG) spinal anesthesia requires a higher minimum local anesthetic dose (MLAD) compared to traditional methods. However, the precise MLAD of ropivacaine for UG cesarean sections remains undetermined. In this study, we ascertained the MLAD of ropivacaine for cesarean section. We also investigated the mechanism underlying the diffusion of ropivacaine within the spinal canal using fluid simulation technology., Patients and Methods: We randomly placed 60 healthy parturients undergoing elective cesarean section with real-time UG spinal anesthesia into Groups I (26-gauge spinal needle) and II (24-gauge spinal needle). For the first parturient in both groups, 15 mg of ropivacaine was administered intrathecally. Based on the effective or ineffective response of the previous parturient, the dose for the subsequent parturient was increased or decreased by 1 mg. Spinal anesthesia characteristics and side effects were recorded. A computer-generated spinal canal model was developed. Leveraging fluid dynamics simulation technology, we documented the diffusion of ropivacaine in the spinal canal using 26-and 24-gauge spinal needles., Results: The MLADs in Groups I and II were 12.728 mg (12.339-13.130 mg) and 9.795 mg (9.491-10.110 mg), respectively. No significant difference was observed in the onset times and durations of sensory or motor blocks, incidence of complications, or neonatal Apgar scores between both groups. Fluid simulation modeling indicated that the 26-gauge spinal needle achieved a higher distribution level more quickly; however, its peak drug concentration was lower compared to the 24-gauge spinal needle., Conclusion: For cesarean section anesthetization, the required MLAD of ropivacaine when using a real-time UG 26-gauge spinal needle is significantly greater than that with a 24-gauge needle. The spinal needle diameter influences ropivacaine's MLAD by markedly affecting its diffusion rate within the spinal canal., Competing Interests: The authors report no conflicts of interest in this work., (© 2024 Zheng et al.)

Quadratus lumborum block is an effective truncal block for postoperative analgesia in patients undergoing abdominal surgeries. We aimed to compare the analgesic efficacy of caudal block versus ultrasonography-guided quadratus lumborum block in pediatric patients undergoing open pyeloplasty. Fifty patients weighing ≤ 16 kg (age ≤ 4 years) with ASA physical status I-II scheduled for elective open pyeloplasty under general anesthesia were randomized into caudal block or transmuscular quadratus lumborum block groups. Fifty patients were included in the analysis. The mean duration of postoperative analgesia in the caudal group was 6.85 ± 1.99 hr, and for the quadratus lumborum block group it was 11.27 ± 3.74 hr ( P < .001). There was no significant difference between the groups in terms of perioperative fentanyl requirement. However, there was a significant difference in postoperative paracetamol requirement between the groups ( P = .005). There was a significant difference in postoperative pain score between the groups at 30 min, 1 hr, 1.5 hr, 2 hr, 8 hr, and 24 hr ( P < .05). Mean heart rate and mean arterial pressure were comparable. No complications were recorded. Quadratus lumborum block was more effective than caudal block in terms of duration of postoperative analgesia and postoperative analgesic consumption., Competing Interests: Name: Shreya B.

Aims: A local injection may be used as an early option in the treatment of Morton's neuroma, and can be performed using various medications. The aim of this study was to compare the effects of injections of hyaluronic acid compared with corticosteroid in the treatment of this condition., Methods: A total of 91 patients were assessed for this trial, of whom 45 were subsequently included and randomized into two groups. One patient was lost to follow-up, leaving 22 patients (24 feet) in each group. The patients in the hyaluronic acid group were treated with three ultrasound-guided injections (one per week) of hyaluronic acid (Osteonil Plus). Those in the corticosteroid group were treated with three ultrasound-guided injections (also one per week) of triamcinolone (Triancil). The patients were evaluated before treatment and at one, three, six, and 12 months after treatment. The primary outcome measure was the visual analogue scale for pain (VAS). Secondary outcome measures included the American Orthopaedic Foot and Ankle Society (AOFAS) score, and complications., Results: Both groups showed significant improvement in VAS and AOFAS scores (p < 0.05) after 12 months. The corticosteroid group had a significantly greater reduction in VAS and increase in AOFAS scores compared with the hyaluronic acid group, at one, three, and six months, but with no significant difference at 12 months. There were no complications in the hyaluronic acid group. There were minor local complications in six patients (six feet) (25.0%) in the corticosteroid group, all with discolouration of the skin at the site of the injection. These minor complications might have been due to the three weekly injections of a relatively high dose of corticosteroid. No patient subsequently underwent excision of the neuroma., Conclusion: An ultrasound-guided corticosteroid injection showed statistically significantly better functional and pain outcomes than an ultrasound-guided injection of hyaluronic acid for the treatment of a Morton's neuroma at many timepoints.

Objective: The increasing utilization of various molecular tests for diagnosing and selecting treatments for patients with malignancies has led to a rising trend in both the frequency of biopsies and the required tissue volume. We aimed to compare the safety of outpatient ultrasound (US)-guided percutaneous liver biopsy (PLB) between the coaxial method with needle track plugging (NTP) and the conventional method., Materials and Methods: This single-center, prospective, randomized controlled study was conducted from October 2022 to May 2023. Patients referred for US-guided PLB with target liver lesions measuring ≥1 cm and requiring ≥3 tissue cores were enrolled. Patients with severe coagulopathy or a substantial volume of ascites were excluded. Patients were randomly assigned to undergo PLB using either the coaxial method with NTP or the conventional method, in a 1:1 ratio, and were subsequently discharged after 2 hours. The primary endpoint was the presence of a patent track sign, defined as a linear color flow along the biopsy track on Doppler US, as an indication of bleeding. The secondary endpoints included clinically significant bleeding, delayed bleeding after discharge, and diagnostic yield. The incidences of these endpoints were compared between the two methods., Results: A total of 107 patients completed the study protocol. Patent track signs were observed significantly less frequently in the coaxial method with NTP group than in the conventional method group: 16.7% (9/54) vs. 35.8% (19/53; P = 0.042). Clinically significant bleeding and delayed bleeding did not occur in either group, and both methods achieved a high diagnostic yield: 94.4% (51/54) vs. 98.1% (52/53; P = 0.624)., Conclusion: Compared with the conventional method, the coaxial method with NTP may potentially be safer, with a reduced risk of overall bleeding complications after PLB when retrieving ≥3 tissue cores. The coaxial method with NTP could be considered a viable option for acquiring multiple liver tissues on an outpatient basis., Competing Interests: The authors have no potential conflicts of interest to disclose., (Copyright © 2024 The Korean Society of Radiology.)

Background: Lipid content in untreated nonobstructive coronary artery lesions is associated with adverse clinical outcomes, and residual in-stent or stent edge lipid may worsen outcomes after percutaneous coronary intervention (PCI)., Methods: Near-infrared spectroscopy-intravascular ultrasound was performed before and after PCI in patients with myocardial infarction. We evaluated the impact of lipid assessed by near-infrared spectroscopy (maximal lipid core burden index over 4 mm [maxLCBI 4mm ]) along with intravascular ultrasound information including residual plaque burden on in-stent or edge-related major adverse cardiac events (MACE) in de novo PCI-treated culprit coronary artery lesions. The primary end point was culprit lesion-related MACE (CL-MACE), defined as cardiac death, myocardial infarction, or unstable or progressive angina either requiring revascularization or with rapid lesion progression and classified as in-stent or stent edge-related., Results: During a median follow-up of 3.8 years, 25 CL-MACE (11 stent edge-related, 13 in-stent, and 1 in-lesion without a stent) occurred in 1041 PCI-treated lesions in 768 patients. Pre-PCI or post-PCI measures of lipid content were not related to in-stent CL-MACE. However, stent edge-related CL-MACE was increased if both the post-PCI stent edge maxLCBI 4mm was greater than the upper quartile (108.7) and the stent edge plaque burden was >50% (adjusted odds ratio, 4.11 [95% CI, 1.12-15.2]; P =0.03)., Conclusions: In PROSPECT II (Providing Regional Observations to Study Predictors of Events in the Coronary Tree), CL stent implantation leaving behind greater stent edge-related lipid and uncovered plaque burden was associated with an increased risk of stent edge-related CL-MACE during follow-up. In contrast, CL lipid content was not related to in-stent CL-MACE., Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT02171065., Competing Interests: Dr Maehara is a consultant to Boston Scientific, Philips, and SpectraWave; and speaker honoraria from Nipro.

Introduction: Robotic-assisted surgery has become increasingly popular because of its potential benefits. Anatomical liver resection (ALR) is a valuable strategy in hepatocellular carcinoma (HCC) management. ALR with indocyanine green (ICG) fluorescence navigation was reported as an effective solution for segment identification. We reported a simple and convenient "preoperative positive staining technique" for laparoscopic ALR to overcome some limitations. To our knowledge, this is the first report of robotic-assisted surgery in which ALR was performed using this technique., Materials and Surgical Technique: A 69-year-old man presented with a 12-mm HCC in segment 8. Preoperative three-dimensional simulation images showed that the fourth-order branch of the portal vein was a tumor-bearing portal pedicle. After anesthesia induction, 1 mL of 0.025 mg/mL ICG was injected percutaneously into this branch under B-mode ultrasound guidance before pneumoperitoneum. A robotic laparoscope was inserted. The preoperative positive staining area was clearly stained on the liver surface with the Firefly mode on the da Vinci Xi system. Based on the demarcation line, the liver parenchymal resection was started. The ICG fluorescence staining area was checked frequently on the resected side of the liver transection plane. Subsequently, the fourth-order portal branch was identified with the ICG fluorescence technique and ligated. Finally, the specimen was resected. The operation took 352 min, with 10 mL of blood loss, and was completed without any operative problems., Discussion: Although many cases are required, the proposed preoperative positive staining technique appears useful for accurate and precise surgery given the increasing application of robotic-assisted hepatectomy., (© 2024 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

Introduction: The objective of the present study was to evaluate morphine consumption and pain scores 24 h postoperatively to compare the effects of a bilateral External Oblique Intercostal (EOI) block with those of a Modified Thoracoabdominal Nerve Block Trough Perichondrial Approach (M-TAPA) block in laparoscopic sleeve gastrectomy (LSG)., Methods: Fifty-eight patients aged between 18 and 65 years of with American Society of Anesthesiologists class II-III were included in this randomized, double-blinded study. Patients were assigned into two groups either EOI block or M-TAPA block. The primary outcome was cumulative morphine consumption within the first postoperative 24 h. Secondary outcomes were numerical rating scale (NRS) scores at rest and during activity, QoR-15 Patient Questionnaire scores, incidence of postoperative nausea and vomiting (PONV), number of patients requiring rescue analgesic and antiemetics drugs, and complications., Results: There was no statistically significant difference between the groups in terms of morphine consumption in the first 24 h (EOI block; 10.74 ± 3.94 mg vs. M-TAPA block; 11.67 ± 4.66 mg, respectively). In addition, no significant difference between the two groups in the NRS and PONV scores, total QoR-15 scores, and the number of patients requiring rescue analgesics and antiemetics., Conclusions: EOI block and M-TAPA block showed similar effectiveness for morphine consumption within 24 h postoperatively and in pain scores in LSG., (© 2024.

Purpose of Review: The purpose of this article is to provide an update of regional anesthesia and its applications in the critical care patient population., Recent Findings: Regional anesthesia including blocks of the abdomen and thorax, head and neck, as well as upper and lower extremities can be used to alleviate pain and assist in managing life-threatening conditions such as cerebral vasospasm and ventricular storm in the ICU population. There have been many advances in these techniques including ultrasound-guidance with innovative approaches that allow for more superficial procedures that are safer for critically ill patients. Regional anesthesia can decrease hospital length of stay (LOS), prevent ICU admission, shorten ICU LOS, and increase ventilator free days and may have mortality benefits., Summary: Pain management in the ICU is an important and sometimes challenging aspect of patient care. Regional anesthetic techniques have more indications and are safe, versatile tools that should be incorporated into care of critically ill patients., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Perclose ProGlide (PPG) Suture-Mediated Closure System™ is safe and can reduce time to hemostasis following procedures requiring arterial access., Aims: We aimed to compare PPG to figure of 8 suture in patients who underwent interventional catheter procedures requiring large bore venous access (LBVA) (≥13 French)., Methods: In this physician-initiated, randomized, single-center study [clinicaltrials.gov ID: NCT04632641], single-stick venous access was obtained under ultrasound guidance. Eligible patients were randomized 1:1, and 100 subjects received allocated treatment to either PPG (n = 47) or figure of 8 suture (n = 53). No femoral arterial access was used in any patient. Primary outcomes were time to achieve hemostasis (TTH) and time to ambulation (TTA). Secondary outcomes were time to discharge (TTD) and vascular-related complications and mortality. Wilcoxon rank-sum test was used to compare TTH, TTA, and TTD., Results: TTH (minutes) was significantly lower in PPG versus figure of 8 suture [median, (Q1, Q3)] [7 (2,10) vs. 11 (10,15) respectively, p < 0.001]. TTA (minutes) was significantly lower in PPG compared to figure of 8 suture [322 (246,452) vs. 403 (353, 633) respectively, p = 0.005]. TTD (minutes) was not significantly different between the PPG and figure of 8 suture arms [1257 (1081, 1544) vs. 1338 (1171,1435), p = 0.650]. There was no difference in minor bleeding or access site hematomas between both arms. No other vascular complications or mortality were reported., Conclusion: PPG use had lower TTH and TTA than figure of 8 suture in a population of patients receiving LBVA procedures. This may encourage same-day discharge in these patients., (© 2024 The Author(s). Catheterization and Cardiovascular Interventions published by Wiley Periodicals LLC.)

Ventricular diverticula are saccule-like structures formed by the protrusion of the ventricular myocardium from the endocardial surface towards the free wall. Most diverticula are muscular structures, and patients usually have no obvious clinical symptoms. However, diverticula may contribute to arrhythmogenesis due to localized myocardial structural disturbances. Right ventricular apical diverticulum (RVAD) is very rare, and we report a case of highly symptomatic accelerated idioventricular rhythm (AIVR) originating from the RVAD that underwent intracardiac echocardiography (ICE)-guided catheter ablation with no recurrence during follow-up., (© 2024 Wiley Periodicals LLC.)

Background and Aims: Emerging data suggest neoadjuvant chemotherapy (NAC) for resectable pancreatic ductal adenocarcinoma (PDAC) is associated with improved survival. However, less than 40% of patients demonstrate a meaningful radiographic response to NAC. EUS-guided radiofrequency ablation (EUS-RFA) has emerged as a new modality to treat PDAC. We hypothesize that NAC plus EUS-RFA can be used in the management of resectable PDAC., Methods: This was a prospective review of PDAC patients meeting the criteria of resectable tumor anatomy who underwent NAC chemotherapy plus EUS-RFA followed by pancreatic resection. Radiographic imaging and perioperative and short-term outcomes were recorded. Surgical pathology specimens were analyzed for treatment response., Results: Three eligible patients with resectable PDAC received 4 months of NAC plus EUS-RFA. One month after completing NAC and EUS-RFA, all 3 patients underwent standard pancreaticoduodenectomy without adverse events. After a 6-week recovery, all patients completed 2 months of postoperative adjuvant chemotherapy., Conclusions: In our institutional experience, this treatment protocol appears to be safe as patients tolerated the combination of chemotherapy and ablation. Patients underwent pancreatic resection with uneventful recovery. This novel neoadjuvant approach may provide a more effective alternative to chemotherapy alone., Competing Interests: Disclosure The following author received research support for this study from Atilla Ertan MD Endowment funding: N.

Study Objective: To compare intravenous lidocaine, ultrasound-guided erector spinae plane block (ESPB), and placebo on the quality of recovery and analgesia after laparoscopic cholecystectomy., Design: A prospective, triple-arm, double-blind, randomized, placebo-controlled non-inferiority trial., Setting: A single tertiary academic medical center., Patients: 126 adults aged 18-65 years undergoing elective laparoscopic cholecystectomy., Interventions: Patients were randomly allocated to one of three groups: intravenous lidocaine infusion (1.5 mg/kg bolus followed by 2 mg/kg/h) plus bilateral ESPB with saline (25 mL per side); bilateral ESPB with 0.25% ropivacaine (25 ml per side) plus placebo infusion; or bilateral ESPB with saline (25 ml per side) plus placebo infusion., Measurements: The primary outcome was the 24-h postoperative Quality of Recovery-15 (QoR-15) score. The non-inferiority of lidocaine versus ESPB was assessed with a margin of -6 points and 97.5% confidence interval (CI). Secondary outcomes included 24-h area under the curve (AUC) for pain scores, morphine consumption, and adverse events., Main Results: 124 patients completed the study. Median (IQR) 24-h QoR-15 scores were 123 (117-127) for lidocaine, 124 (119-126) for ESPB, and 112 (108-117) for placebo. Lidocaine was non-inferior to ESPB (median difference  -1, 97.5% CI: -4 to ∞). Both lidocaine (median difference 9, 95% CI: 6-12, P < 0.001) and ESPB (median difference 10, 95% CI: 7-13, P < 0.001) were superior to placebo. AUC for pain scores and morphine use were lower with lidocaine and ESPB versus placebo (P < 0.001 for all), with no significant differences between lidocaine and ESPB. One ESPB patient reported a transient metallic taste; no other block-related complications occurred., Conclusions: For patients undergoing laparoscopic cholecystectomy, intravenous lidocaine provides a non-inferior quality of recovery compared to ESPB without requiring specialized regional anesthesia procedures. Lidocaine may offer a practical and accessible alternative within multimodal analgesia pathways., Competing Interests: Declaration of competing interest The author reports no conflicts of interest in this work., (Copyright © 2024 Elsevier Inc.

Objective: The purpose of this study was to investigate the efficacy and safety of endoscopic ultrasound (EUS)-guided injection of cyanoacrylate (CYA) and transjugular intrahepatic portal shunts (TIPSs) in the treatment of patients with cirrhosis with ruptured gastric varices., Methods: In this retrospective study, 105 patients with liver cirrhosis and gastric varicose veins who were admitted to the First Affiliated Hospital of Anhui Medical University between April 2018 and April 2023 without nonselective β-blockers treatment and no portal vein thrombosis were evaluated. The patients were divided into the transjugular intrahepatic portal shunt (TIPS) group (n = 60) and the EUS-CYA group (n = 45) for the purpose of evaluating postoperative rebleeding rates, complications, survival rates, and other factors., Results: During the follow-up, there was no significant difference in the rebleeding rates between the TIPS group and EUS-CYA group within 3 months (5% vs 2.2%; P = 0.825; 10% vs 20%, P = 0.147). However, the TIPS group had significantly lower rebleeding rates than the EUS-CYA group at 6 months (10% vs 33.3%; P = 0.030) and 1 year or longer (11.7% vs 42.2%; P < 0.01). In terms of hepatic encephalopathy, the incidence rate of the TIPS group was significantly higher than that of the EUS-CYA group (20% vs 2.2%; P = 0.006). In addition, there was no difference in the survival rates between the two groups (93.3% vs 97.8%; P = 0.552)., Conclusions: TIPS is superior to EUS in preventing rebleeding in patients with ruptured varices of the fundus, but it has a higher incidence of hepatic encephalopathy, and there is no difference in long-term survival between the two groups., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.
