Background: Acute postoperative urinary retention (POUR) is a common complication in patients with ischemic stroke following femoral artery puncture (FAP), leading to discomfort, delayed hospital discharge, and increased patient morbidity. The relevant risk factors are unclear; thus, a predictive tool is required to guide treatment decisions. Objective: To develop and validate a nomogram to predict acute POUR in patients with ischemic stroke following FAP. Methods: We retrospectively collected cases from 1729 patients with ischemic stroke from the electronic record system of Jiangmen Central Hospital from January 2021 to December 2023. A total of 731 patients were randomly divided into development (n = 511, 70%) and validation (n = 220, 30%) groups. Univariate and multivariate logistic regression analyses with backward stepwise regression were used to select the predictive variables, and a nomogram was developed. The discrimination was evaluated based on the area under the curve (AUC). Calibration was assessed using calibration plots and the Hosmer-Lemeshow test. Clinical applications were evaluated using decision curve analysis (DCA). Results: The incidence of acute POUR was 12.72%. Preoperative statin use within 24 h, operation type, intraoperative infusion, postoperative water intake within 3 h, postoperative pain, and postoperative anxiety were included in the nomogram. The AUC values were 0.764 [95% confidence interval (CI): 0.705-0.825] in the development group and 0.741 (95% CI: 0.615-0.856) in the validation group. The calibration plots showed good calibration. The p values in the Hosmer-Lemeshow tests were 0.962 and 0.315 for the development and validation groups, respectively. The DCA showed that patients could benefit from this nomogram. Conclusion: A nomogram was developed to successfully predict acute POUR in patients with ischemic stroke following FAP. This nomogram is a convenient and effective tool for clinicians to aid in the prevention and early intervention of acute POUR. [ABSTRACT FROM AUTHOR]

Background: Central venous catheterization, crucial for device insertion, monitoring, medication, and fluid resuscitation, commonly uses the subclavian, internal jugular, and femoral veins. Despite its general safety, complications like arterial puncture can be life-threatening, requiring rapid diagnosis and treatment. Case presentation: A 74-year-old woman in the recovery phase of cerebral infarction underwent right subclavian vein catheterization. The catheter was mistakenly placed in the brachiocephalic trunk, with its tip in the ascending aorta, as confirmed by computed tomography (CT) and digital subtraction angiography (DSA). With the high surgical risk and the complexity of endovascular treatment, catheter replacement was chosen. One month after the initial placement, the catheter was replaced with a smaller one, and another month later, it was retracted without complications. Follow-up CT and DSA revealed no leakage, with the patient's vitals remaining stable. A three-month post-discharge phone follow-up confirmed the patient's continued stability. Conclusion: This case demonstrates the effective use of a catheter replacement technique as a minimally invasive repair method when other options are impractical. Ultrasound guidance is also recommended to improve the procedure's accuracy and safety. [ABSTRACT FROM AUTHOR]

Background: Hemostatic devices are now frequently used in femoral artery punctures, and the Angio-Seal (Terumo, Tokyo, Japan) is one of the most commonly used devices for closure of the femoral artery because it provides rapid hemostasis. Although device failure rarely occurs, if the collagen falls into the femoral artery, it may lead to severe limb ischemia. Herein, we describe a case of a novel endovascular technique for the treatment of Angio-Seal arterial closure device failure. Case presentation: The patient in Case 1 was a 75-year-old man with severe left limb claudication. We used a contralateral antegrade approach and used the Angio-Seal for hemostasis. However, the Angio-Seal collagen and footplate dropped and stopped at the bifurcation of the superficial femoral artery and deep femoral artery. The collagen with the footplate was caught with myocardial biotome forceps (MBF) and pulled into the external iliac artery (EIA). The distal common femoral artery (CFA) was punctured, and we delivered a 10.0- × 80-mm stent (SMART®; Cordis, USA) to the EIA from the ipsilateral sheath. The stent was deployed at the EIA and crushed the collagen. The patient in Case 2 was an 88-year-old man with rest pain in the right limb. The right CFA was punctured using an ipsilateral approach and the Angio-Seal was used for hemostasis. The Angio-Seal collagen with the footplate dropped into the bifurcation of the deep femoral artery. The collagen and footplate were caught with MBF and pulled up to the EIA. The right CFA was punctured and a 10.0- × 60-mm stent (SMART®; Cordis) was delivered from the ipsilateral sheath. The stent was deployed at the EIA and crushed the collagen with the footplate. Conclusions: MBF were used to grasp the dislodged collagen with the anchor and cover it with a stent at the iliac artery. This may be a useful bailout technique for Angio-Seal dislodgement.

OBJECTIVES: In the realm of acute pain management within emergency departments (EDs), the prevalent reliance on systemic analgesics, notably opioids, presents challenges due to associated risks and suboptimal efficacy. The emerging alternative of ultrasound-guided nerve blocks (USGNBs) has shown promise in prospective studies. However, the safety and efficacy of USGNBs when performed by emergency medicine practitioners remain largely unexplored, necessitating this study to address the research gap. The primary objectives of this study were to assess the efficacy of Emergency physician-performed USGNBs and changes in patient-reported pain (pre- and postnerve block) at 15 and 30 min. In addition, the time taken to perform nerve blocks, type of nerve block, frequency, indications, procedure time, and complications were all studied. METHODS: Conducted at a Tertiary Care Teaching Hospital in Pune, India, this single-center, retrospective observational study aimed to evaluate the effectiveness of USGNBs in the ED context. A retrospective analysis covered 274 emergency practitioner-performed USGNBs recorded from January 2022 to December 2023. Participants included consecutive ED patients consenting to nerve blocks, with practitioners utilizing bupivacaine (0.25%) and ropivacaine (0.25%) based on individual preferences. The study systematically recorded patient demographics, block types, indications, complications, and pre- and postpain scores on a Numerical Rating Scale. RESULTS: The study demonstrated a significant reduction in pain scores post-USGNB, with an average decrease of 2.9 ± 1.08 at 15 min and 5.8 ± 1.39 at 30 min. Commonly performed blocks included the femoral nerve, fascia iliaca, and serratus anterior, with notable pain relief in fracture management cases. Procedural durations varied, ranging from 2 to 12 min, while four complications were reported, including diaphragmatic paresis and arterial punctures during interscalene nerve block and fascia iliac compartment blocks, respectively. CONCLUSION: This extensive study in an academic ED setting supports the proficiency of emergency practitioners in performing USGNBs. The findings emphasize the transformative potential of USGNBs in academic ED pain management, showcasing notable pain reduction and minimal complications. These results advocate for the integration of advanced pain relief techniques into emergency medicine training programs, contributing to a comprehensive approach to acute pain management.

Arterial puncture is a painful procedure performed to assess patients’ respiratory status. Pain is a stressful situation for unconscious patients as they cannot communicate their feeling verbally. To control patients’ pain and prevent the adverse effects of painkillers, nonpharmacological pain management strategies have been solicited. The aim of this study is to investigate the effect of cryoanalgesia on unconscious patients’ pain during arterial puncture. We adopted a quasi-experimental one-group research design. A sample of 86 unconscious patients in a surgical intensive care unit were recruited in this study. The intervention was applying an ice pack over the puncture site for 5 minutes before the arterial puncture procedure. Pain was assessed for 2 times; before and after application of cryoanalgesia. A statistically significant difference in participants’ pain scores between pre-tests and post-tests was noted. For the intubated ventilated participants, the mean pain score before and after applying cryoanalgesia was 5.26 versus 4.00 (P ≤ .05). For the non-intubated or intubated non-ventilated participants, the mean pain score was 6.66 versus 4.63 (P ≤ .05). Cryoanalgesia is a feasible and effective method incorporate during arterial puncture along with standard procedure elements to achieve maximum pain reduction for unconscious patients during arterial punctures.

Objective: To investigate the mid-term efficacy and patency rate of TurboHawk peripheral plaque excision system in the treatment of femoral popliteal artery lesions with different Global Limb Anatomic Staging System (GLASS) grades. Methods: The clinical data of 141 patients with femoral popliteal arteriosclerosis obliterans who were treated with TurboHawk from January 2018 to July 2022 in our institution were retrospectively analyzed. There were 109 male patients and 32 female patients. Recordings were made of the patient's symptoms of limb ischemia, technical success rate, primary patency rate of target vessels, ankle brachial index (ABI), GLASS grades, postoperative complications, and a statistical analysis with the patient's preoperative treatment was conducted. Results: All patients had improved limb ischemia symptoms to varying degrees after surgery, with a technical success rate of 100% (femoral artery puncture and superficial femoral artery recanalization) without bleeding, hematoma, pseudoaneurysm, arteriovenous fistula or other complications. The follow-up period was 1-24 months, during which the severity of claudication, resting pain, and toe ulcers significantly improved. The primary patency rate of the target vessel was 98.58% (139/141), and the ABI significantly increased on the second day, three months, and six months after surgery compared to before surgery. No major adverse events were found during follow-up. The patency rates at 1, 6, 12 and 24 months after intervention were 100%, 80%, 75% and 60% respectively. Conclusion: The mid-term efficacy and patency rate of TurboHawk in the treatment of femoral popliteal artery lesions with GLASS I patients have the best mid-term prognosis, the highest mid-term survival rate, and the highest vascular patency. The plaque removal system has proven to be an effective treatment for individual localized chronic total occlusion lesions. Additionally, the TurboHawk system provides a safe and minimally invasive treatment alternative for superficial femoral artery conditions, achieving significant therapeutic results within a brief period.

Background: Stenosis resulting in dysfunctional dialysis access may occur simultaneously on the anastomotic and central venous side. The purpose of this study was to retrospectively evaluate the feasibility of a single sheath inverse technique using the vertical puncture approach to perform bidirectional transvenous percutaneous transluminal angioplasty (PTA) from a single sheath for such dialysis access stenoses. Materials and Methods: Twenty patients (26 cases; 13 males; median age, 74 [range: 50–89] years) who underwent PTA using the sheath inverse technique for dysfunctional arteriovenous fistula stenoses between April 2019 and June 2023 were included. All procedures were performed in an outpatient setting. A 4-cm sheath (4Fr, four cases; 5Fr, 19 cases; 6Fr, three cases) was inserted by vertical puncture through a cutaneous vein in the forearm (20 cases) or upper arm (six cases). After treating one side of the lesion, the sheath was reversed to treat the lesion on the opposite side. The vessel diameter at the sheath insertion site, the success rate of sheath inversion, the number of PTA balloon catheters used, the PTA success rate, adverse events, and primary and secondary patency rates up to one year after PTA were evaluated. Results: The median diameter at the sheath indwelling site was 5.2 (range: 3.6–9.5) mm, and sheath inversion was successful in all cases, eliminating the need to place an additional sheath at another site for contralateral stricture treatment. The number of balloon catheters used was one and two in 17 (65%) and eight cases (31%), respectively, and three in one case wherein a drug-coated balloon was used. PTA was successful in all cases and major complications were not observed. However, in one case wherein a sheath had to be placed at the arterial needle puncture site, the skin was hard, leading to difficulty in inversion, and transient venous spasm occurred post-inversion. The primary patency rates at 3, 6 and 12 months after the PTA were 87.5%, 41.7%, and 20.8%, respectively. The secondary patency rates at 6 and 12 months were 100% and 75%, respectively. Conclusion: The single-sheath inverse technique for arteriovenous fistulas was feasible without sheath withdrawal. [ABSTRACT FROM AUTHOR]

Currently, there is a decreasing trend in the utilization of central venous catheters among medical practitioners. However, the continued relevance of central venous catheters persists, particularly in scenarios involving emergent or critically ill patients where peripheral venous access proves challenging. The insertion of central venous catheters facilitates rapid delivery of fluids and pharmacotherapy crucial for resuscitative efforts. Employing real-time ultrasound guidance enhances procedural safety from mechanical injuries, increases success rate with limited attempt and diminishes associated risks like pneumothorax, arterial puncture, and hemorrhage. Emphasizing infection prevention remains paramount. The present article underscored contemporary and safer procedural methodologies for central venous catheterization, alongside adept management of procedural complications. [ABSTRACT FROM AUTHOR]

Introduction: Central venous access plays a crucial role in various clinical settings, and ultrasound guidance has become increasingly popular for improving its safety and success rates. The aim of this meta‐analysis was to compare the short‐axis (SAX) and long‐axis (LAX) ultrasound‐guided techniques for internal jugular vein (IJV) cannulation in terms of first needle pass success rate, number of cannulation attempts, access time, guidewire insertion time, posterior IJV wall puncture, arterial puncture, haematoma and catheter‐related bloodstream infection. Methods: A comprehensive literature search was conducted, and randomised controlled trials (RCTs) comparing SAX and LAX techniques for IJV cannulation on adults were included. Results: A total of 11 RCTs involving 1183 patients were included in the meta‐analysis. The SAX technique demonstrated a significantly greater first needle pass success rate and faster IJV access time compared to the LAX technique. However, more posterior IJV wall puncture was significantly associated with the SAX technique. There was no significant difference between the two techniques in terms of number of cannulation attempts, guidewire insertion time, arterial puncture, haematoma and catheter‐related bloodstream infection. Conclusion: This meta‐analysis suggests that the SAX technique may have advantages over the LAX technique in terms of first needle pass success rate and potentially reducing cannulation attempts and access time. However, the occurrence of posterior IJV wall puncture raises concerns. The decision on the choice of technique should be based on individual patient factors and operator proficiency.

Puncture-site complications in interventional radiology sometimes cause severe conditions. Vascular closure devices play an important role in preventing puncture-site complications. Vascular closure devices are divided into 2 types, the directly suturing or clipping type (active approximators) and adherent sealant types (passive approximators). However, which types of vascular closure device are the safest and most effective for achieving hemostasis remains unclear. We analyzed the efficacy of each type of vascular closure device and risk factors for puncture-site complications. This study investigated 327 consecutive cases of neuroendovascular surgery using a transfemoral procedure during a 2-year study period. Passive approximators (Angioseal [St Jude Medical, Saint Paul, MN] and Exoseal [Cordis Corporation, Miami, FL]) were mainly used in the first half and active approximators (Perclose [Abbot Vascular, Santa Clara, CA]) in the second. We compared groups and estimated risk factors for puncture-site complications. All procedures were successful. Comparing groups with and without puncture-site complications, use of passive approximators and ≥3 antithrombotic medications tended to be more frequent and distance from skin to femoral artery and body mass index tended to be lower in the group with complications without significance. The cutoff for femoral artery depth calculated from a receiver operating characteristic curve was 16.43 mm. Multivariate analysis revealed ≥3 antithrombotic medications (P = 0.002, OR 15.29, 95% CI 2.76–85.76) and passive approximator use in patients with femoral artery depth <16.43 mm (P < 0.001, OR 17.08, 95% CI 2.95–57.80) were significantly higher in the group with puncture-site complications. Passive approximator use in patients with shallow femoral artery depth increases puncture-site complications in neuroendovascular treatment. [ABSTRACT FROM AUTHOR]

We have previously introduced a blood delivery method via femoral artery cannulation to provide perfusion to the organs in the lower part of the body during pediatric aortic arch repair surgeries. In the original procedure, the femoral artery cannulation was performed after the patient had been covered with a sterile drape. Here, we suggest that the femoral artery cannulation should be performed before the patient is draped to allow optimal visibility of the target artery and puncture needle via aseptic real-time ultrasound-guided technique by reducing the inclusions between the patient's skin and ultrasound probe which attenuate the ultrasound beam.

Aim: We conducted a meta‐analysis comparing the invasiveness of automatic lancet devices, which can collect adequate amount of blood at shallow puncture depths, with conventional manual lance devices (lancet or needle) to statistically identify less invasive instruments for neonatal heel lance. Methods: We searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, and Ichushi databases for studies comparing the invasiveness between automatic lancet and manual lancet or needle in term and preterm neonates in neonatal intensive care unit. Results: This review included 9 out of 449 searched articles, with 673 neonates. Automatic lancet had significantly lower pain scores (standardised mean difference: −2.0, 95% confidence interval: −3.3 to −0.7), heart rate (mean difference: −8.0, 95% confidence interval: −13.8 to −2.1), cry duration (mean difference: −21.5, 95% confidence interval: −32.5 to −10.4), number of punctures (mean difference: −0.6, 95% confidence interval: −1.1 to −0.2), and duration of procedures (mean difference: −37.7, 95% confidence interval: −75.2 to −0.2) than manual lancet or needle. Furthermore, peripheral oxygen saturation was significantly higher in automatic lancet than in manual lancet or needle (mean difference: 4.5, 95% confidence interval: 0.5–8.5). Conclusion: Automatic heel lancet devices were less invasive than manual heel lance devices (lancet or needle). [ABSTRACT FROM AUTHOR]

Background: Insertion of electrode catheters into the coronary sinus (CS) through the right internal jugular vein (RIJV) carries risks of pneumothorax and severe hematoma formation. This study was performed to compare the safety and feasibility of catheterization through the left cubital superficial vein versus the RIJV. Methods: This prospective nonrandomized study involved consecutive patients who underwent catheter ablation from September 2021 to February 2023. Blind puncture techniques were used in the left cubital vein group; ultrasound‐guided insertion was performed in the RIJV group. The success rates of sheath insertion and CS catheterization, the procedure and fluoroscopy times of CS cannulation, and complications were compared between groups. Results: The left cubital vein group comprised 152 patients, and the RIJV group comprised 58 patients. The sheath insertion success rate was significantly lower in the cubital vein group than in the RIJV group (84.9% vs 100%, respectively; p =.0008). In the cubital vein group, blind puncture attempts failed in 20 patients; three patients developed guidewire‐induced venous injury. One arterial puncture occurred in the RIJV group. After successful sheath insertion, no significant differences were observed in the CS cannulation success rate (97% vs 100%, p =.55), procedure time (median [range], 93 [51–174] vs 74 [44–129] s; p =.19), or fluoroscopy time (median [range], 66 [36–134] vs 48 [30–92] s; p =.17). No serious complications requiring procedural discontinuation occurred. Conclusion: The left cubital vein approach is practical, offering a viable alternative to the RIJV approach.

Purpose: To assess multicenter two-year patency outcomes of endovascular arteriovenous fistulas (endoAVF) created with the WavelinQ device. Materials and Methods: Patients who had fistulas created at three centers from January 2018 to December 2020 were included in this retrospective study. In total, 112 patients underwent endoAVF creation [40 females, 72 males; mean age 60 years (range 18–88)]. Data collected included patient demographics, location of fistula creation, interventions performed, and brachial artery flows pre- and post-creation. Two-year cumulative patency, functional patency, and primary patency were assessed with Kaplan–Meier methodology. Factors affecting patency and maturation were examined using the Cox proportional hazards model. Results: Technical success defined as angiographically successful endoAVF creation was 97.3% (109/112). In 11 patients the fistula did not mature for dialysis use. For 98 patients (87%) with endoAVF maturation, 12- and 24-month cumulative patency was 94.3% and 91.7%. Functional patency (two-needle cannulation) at 12 and 24 months was 95.7% and 92.7%, respectively. Median maturation time is 95 days (IQR 51–231 days). Male gender and brachial vein coiling at the time of endoAVF creation were predictive of maturation. There were 34 censored events (four patients undergoing renal transplantation; 30 patients deceased). Number of reinterventions per patient year was 0.73 where 43 were maturation procedures and 101 were maintenance procedures. One Grade 3 complication occurred of arterial access puncture site pseudoaneurysm. Conclusion: A high two-year functional and cumulative patency following endoAVF creation with the WavelinQ device was observed in this multicenter real-world experience Level of Evidence: 3 Level of Evidence III [ABSTRACT FROM AUTHOR]

Purpose: Ultrasound-guided supraclavicular catheterization (UGSC) of the brachiocephalic vein (BCV) for long-term tunneled central venous catheter (tCVC) insertion may be safer than the internal jugular vein approach due to its superior field of view. We examined the clinical outcomes of tCVC insertions performed by junior residents through UGSC of the BCV. Patients and methods: From January 2018 to December 2023, we assessed clinical outcomes and compared the experience levels of surgeons conducting tCVC insertions. Surgeons were categorized into three groups: junior residency (JR), senior residency (SR), and board-certified pediatric surgeons (BCPS). Results: 177 tCVC insertions were done on 146 patients. Intraoperative complications included 6 cases of arterial puncture, 1 case of pneumothorax, 1 case of over insertion of catheter tip, and 1 case of suspected hemothorax. Distribution across groups was as follows: 28 cases (15.8%) in JR group, 92 (52.0%) in SR group, and 57 (32.2%) in BCPS group. Although the JR group exhibited longer operation times than the BCPS group, no significant differences in intraoperative complications were noted. Conclusion: Junior residents can safely perform UGSC for tCVC insertion. However, careful consideration of complications such as arterial or thoracic puncture is essential and case selection should be based on experience. [ABSTRACT FROM AUTHOR]

Background: The trans femoral ipsilateral approach is often adopted for endovascular treatment (EVT) for better steerability of guidewires or better device deliverability. However, contrary to the trans femoral contralateral approach, ipsilateral antegrade puncture sometimes causes peculiar bleeding complications. Case presentation: A 76-year-old female underwent EVT for chronic occlusion of the left superficial femoral artery (SFA) via the ipsilateral antegrade approach. After guidewire passage, we inflated the drug-coated balloons, but angiography showed blood flow stasis at the mid segment of the SFA. We also ensured prolonged balloon inflation, which resulted in favorable blood flow. While trying to ensure hemostasis, the blood pressure remained decreased, but neither bleeding nor superficial hematoma were observed at the puncture site. After hemostasis was achieved, we removed the surgical drape and noticed a swelling in the mid-portion of the thigh, distant from the puncture point. We then approached the left common femoral artery (CFA) contralaterally. Angiography showed continuous bleeding from a little bit distally to the sheath insertion point that was spreading through an intramuscular space. We stopped the bleeding with balloon tamponade inside the CFA. Angiography after hemostasis demonstrated blood flow stasis at the mid-segment of the SFA, similarly as that seen before. We confirmed compression of the SFA by a large hematoma using both intra- and extra- vascular ultrasound. Therefore, we deployed a self-expandable stent at the compressed SFA position. Finally, we achieved favorable blood flow on angiography. Conclusion: We encountered a case that latent bleeding unrecognized in the surgical field persisted while prolonged inflation of DCB was conducted at just proximal SFA. We could have avoided bailout stenting by noticing the bleeding incident in a timely manner. Prediction and prevention are essential for all kinds of procedural complications in EVT.

Objective: To evaluate the application of different uterine artery embolization procedures under balloon occlusion of the abdominal aorta in patients with Placenta Accreta Spectrum (PAS) undergoing cesarean section. Materials and Methods: A retrospective analysis was performed on clinical data from 72 patients who underwent uterine artery embolization for hemostasis during cesarean section with PAS. The patients were divided into two groups according to the embolization method used during surgery: group A (n = 43) underwent uterine artery embolization by withdrawing the balloon and inserting a Cobra catheter into the uterine artery for embolization, while group B (n = 29) underwent uterine artery embolization with a Cobra catheter inserted via contralateral puncture of the femoral artery and balloon occlusion. General information, surgical data, and postoperative recovery were compared between the 2 groups. Results: The bleeding and transfusion volumes were lower in group B than in group A and the differences between the 2 groups were statistically significant. There were no significant differences in surgical duration, number of embolized vessels, length of hospital stay, postoperative complications, or menstrual recovery between the 2 groups. Conclusion: For patients with PAS undergoing cesarean section, uterine artery embolization for hemostasis is preferably performed by inserting a Cobra catheter via contralateral puncture of the femoral artery under abdominal aortic balloon occlusion.

Positive susceptibility vessel sign (SVS) in patients with acute ischaemic stroke has been associated with friable red blood cell-rich clots and more effective recanalisation using stent retrievers versus contact aspiration. We compared the safety and efficacy of stent retrievers plus contact aspiration (combined technique) versus contact aspiration alone as the first-line thrombectomy technique in patients with acute ischaemic anterior circulation stroke and SVS-positive occlusions. Adaptive Endovascular Strategy to the Clot MRI in Large Intracranial Vessel Occlusion (VECTOR) was a prospective, randomised, open-label study with blinded evaluation. Patients with SVS-positive anterior circulation occlusions on pretreatment MRI and arterial puncture within 24 h of symptom onset were enrolled from 22 centres in France. A centralised web-based method was used by interventional neuroradiologists for dynamic randomisation by minimisation. Patients were randomly assigned 1:1 to the combined technique or contact aspiration alone. The primary outcome was expanded Thrombolysis in Cerebral Infarction (eTICI) grade 2c or 3 reperfusion after three or fewer passes on post-treatment angiogram, adjudicated by a blinded independent central imaging core laboratory. The intention-to-treat population was used to assess the primary and secondary outcomes. This trial is registered with ClinicalTrials.gov (NCT04139486) and is complete. Between Nov 26, 2019, and Feb 14, 2022, 526 patients were enrolled, of whom 521 constituted the intention-to-treat population (combined technique, n=263; contact aspiration alone, n=258). The median age of participants was 74·9 years (IQR 64·4–83·3); 284 (55%) were female and 237 (45%) male. The primary outcome did not differ significantly between groups (152 [58%] of 263 patients for the combined technique vs 135 [52%] of 258 for contact aspiration; odds ratio [OR] 1·27; 95% CI 0·88–1·83; p=0·19). Procedure-related adverse events occurred in 32 (12%) of 263 patients in the combined technique group and 27 (11%) of 257 in the contact aspiration group (OR 1·14; 0·65–2·00; p=0·65). The most common adverse event was intracerebral haemorrhage (146 [56%] of 259 patients for the combined technique vs 123 [49%] of 251 for contact aspiration; OR 1·32; 0·91–1·90; p=0·13). All-cause mortality at 3 months occurred in 57 (23%) of 251 patients in the combined technique group and 48 (19%) of 247 in the contact aspiration group (OR 1·19; 0·76–1·86; p=0·45), none of which was treatment-related. The results of the VECTOR trial do not show superiority of the combined stent retriever plus contact aspiration technique over contact aspiration alone in patients with SVS-positive occlusion with respect to achieving eTICI 2c–3 within three passes. These findings support the use of either the combined technique or contact aspiration alone as the initial thrombectomy strategy in patients with acute anterior circulation stroke with SVS on pretreatment MRI.

This pilot study aimed to evaluate safety and tissue sampling from subepithelial lesions (SEL) in the upper gastrointestinal tract with a novel electric motor driven endoscopic ultrasonography (EUS)-guided 17-gauge (G) size core needle biopsy (CNB) instrument. An investigator-led prospective open label, performance and safety control study, including seven patients (female n = 4, median 71 y, range 28–75) with a determined SEL (median size 30 mm, range 17–150 mm) in the upper digestive tract (stomach n = 6, duodenum n = 1) were eligible and later followed up 14 days after index procedure. All investigations were completed according to protocol with three FNB 22-G passes with four fanning strokes and two EndoDrill® 17-G passes with three fanning strokes. Quality of samples as 'visible pieces' (>5 mm): FNB (n = 5/7) (fragmented/blood imbibed n = 1, poor tissue quantity n = 1) compared with 17-G CNB (n = 7/7). Histological result which led to final diagnosis (leiomyoma n = 2, adenocarcinoma n = 1, schwannoma n = 1, neuroendocrine tumour n = 1, desmoid tumour n = 1 and gastrointestinal stromal tumour (GIST) n = 1) could be obtained with the 17-G CNB instrument in all seven patients. FNB technique reached correct diagnosis in six patients. No serious adverse event were recorded. By using an electric driven 17-G biopsy device, a true cylinder of core tissue can be obtained in one single puncture from the area of interest reducing the need for a second sampling. The absolute benefit of EUS-guided CNB is that the sample can be handled and histologically prepared in the same manner as standard percutaneous core needle sample, e.g., breast and prostate cancer.

Purpose: The blood flow restriction (BFR) training is an effective approach to promoting muscle strength, muscle hypertrophy, and regulating the peripheral vascular system. It is recommended to use to the percentage of individual arterial occlusion pressure (AOP) to ensure safety and effectiveness. The gold standard method for assessing arterial occlusive disease is typically measured using Doppler ultrasound. However, its high cost and limited accessibility restrict its use in clinical and practical applications. A novel wearable BFR training device (Airbands) with automatic AOP assessment provides an alternative solution. This study aims to examine the reliability and validity of the wearable BFR training device. Methods: Ninety-two participants (46 female and 46 male) were recruited for this study. Participants were positioned in the supine position with the wearable BFR training device placed on the proximal portion of the right thigh. AOP was measured automatically by the software program and manually by gradually increasing the pressure until the pulse was no longer detected by color Doppler ultrasound, respectively. Validity, inter-rater reliability, and test-retest reliability were assessed by intraclass correlation coefficients (ICC) and Bland-Altman analysis. Results: The wearable BFR training device demonstrated good validity (ICC = 0.85, mean difference = 4.1 ± 13.8 mmHg [95% CI: -23.0 to 31.2]), excellent interrater reliability (ICC = 0.97, mean difference = -1.4 ± 6.7 mmHg [95% CI: -14.4 to 11.7]), and excellent test-retest reliability (ICC = 0.94, mean difference = 0.6 ± 8.6 mmHg [95% CI: -16.3 to 17.5]) for the assessment of AOP. These results were robust in both male and female subgroups. Conclusion: The wearable BFR training device can be used as a valid and reliable tool to assess the AOP of the lower limb in the supine position during BFR training. [ABSTRACT FROM AUTHOR]

CT angiography might be a suitable procedure to avoid arterial puncture in combined intracavitary and interstitial brachytherapy for cervical cancer curatively treated with combined chemoradiation and brachytherapy boost. Data in the literature about this technique are scarce. We introduced this method and collected brachytherapy data from patients treated in our department between May 2021 and April 2024. We analyzed the applicator subtype, needle insertion (planned versus implanted), implanted depth and the role of CT angiography in selecting needle trajectories and insertion depths. None of the patients managed through this protocol experienced atrial puncture and consequent hemorrhage. Needle positions were accurately selected with the aid of CT angiography with proper coverage of brachytherapy targets and avoidance of organs at risk. CT angiography is a promising method for guiding needle insertion during interstitial brachytherapy. [ABSTRACT FROM AUTHOR]

Patients with previous interatrial shunt device (IASD) implantation may face greater challenges during future left atrial interventional procedures. Herein, we report the first case of left atrial appendage closure (LAAC) in a patient with previous IASD implantation. The patient successfully underwent LAAC using the LAmbre device without complications. [ABSTRACT FROM AUTHOR]

Introduction: The purpose of this study was to report our initial experience of using a large-bore (0.096″ inner diameter) access catheter in neurovascular interventions. Methods: Data were retrospectively collected from 5 sites in the US for neurovascular procedures performed using a large-bore access catheter. The effectiveness outcome was technical success, defined as the access catheter's successfully reaching its target vessel without conversion to direct carotid puncture or to a smaller-bore access catheter and successfully completing the intended neurointervention. Results: One hundred and thirteen procedures performed in 112 patients were included in this study. The mean age of the patients was 67.5 years (SD 16.2), and about half (49.1%) were female. The most common primary access sites were the femoral (64.6%) or radial (32.7%) artery. Challenging anatomic variations included severe vessel tortuosity (26/81, 32.1%), type II aortic arch (17/88, 19.3%), type III aortic arch (14/88, 15.9%), bovine arch (16/104, 15.4%), severe angle (<30°) between the subclavian and target vessel (11/74, 14.9%), and subclavian loop (7/79, 8.9%). The median access time to branch view was 18 min (IQR 11-28, N = 75). The technical success rate was 94.7%. Two dissections (1.8%) were related to the large-bore access catheter. Access site complications occurred in 2 patients (1.8%). Four additional symptomatic periprocedural complications not related to the large-bore access catheter occurred (7.1%). Conclusion: For neurovascular interventions, a 0.096″ inner diameter access catheter could be used with both femoral and radial arterial approaches, had a high technical success rate, and had a low rate of periprocedural complications.

Introduction: The standard approaches to ultrasound-guided central line insertion by Short Axis (SAX) and Long Axis (LAX) have limitations. The Medial Oblique Axis (M-OAX) approach allows visualisation of the length of the needle in real-time along with both the artery and vein. Aim: To compare the three approaches for ultrasound-guided right Internal Jugular Vein (IJV) cannulation with respect to ease of access and complications. Materials and Methods: A total of 171 patients scheduled to undergo right IJV cannulation were divided equally into three groups-SAX (Group-1), LAX (Group-2), and M-OAX (Group-3). They were compared with respect to first pass success, Venous Access Time (VAT), guide wire insertion time, catheterisation time, and complications. Continuous variables were compared with Analysis of Variance (ANOVA) test. Categorical variables were analysed using the Chi-square test. The p-value <0.05 was considered significant. Results: First pass success was 55 (96.49%), 53(92.98%), and 54 (94.74%) in groups 1, 2, and 3, respectively. The VAT, guidewire insertion time, and catheterisation time were significantly lesser in Groups 1 and 3 compared to 2 (p<0.001). Two cases of carotid artery puncture were noted in Group-2, though statistically not significant (p>0.05). Conclusion: The medial oblique approach to IJV cannulation combines the advantages of both LAX and SAX and is a safer alternative with easier and faster venous access. [ABSTRACT FROM AUTHOR]

The editorial discusses the importance of choosing the right insertion site for central venous catheters in preventing infections in intensive care units. The subclavian site is generally preferred for reducing bloodstream infections, but other factors such as mechanical complications and patient conditions should also be considered. A recent French study found similar infection rates across different insertion sites, but limitations in the study design suggest that the choice of insertion site still matters. The editorial provides an algorithm to help clinicians make informed decisions based on individual patient needs and conditions. [Extracted from the article]

The aim of this study was to assess whether adding Ca2+ to aggregate or native forms of β -lactoglobulin alters gut hormone secretion, gastric emptying rates and energy intake in healthy men and women. Fifteen healthy adults (mean ± sd: 9M/6F, age: 24 ± 5 years) completed four trials in a randomised, double-blind, crossover design. Participants consumed test drinks consisting of 30 g of β -lactoglobulin in a native form with (NATIVE + MINERALS) and without (NATIVE) a Ca2+-rich mineral supplement and in an aggregated form both with (AGGREG + MINERALS) and without the mineral supplement (AGGREG). Arterialised blood was sampled for 120 min postprandially to determine gut hormone concentrations. Gastric emptying was determined using 13C-acetate and 13C-octanoate, and energy intake was assessed with an ad libitum meal at 120 min. A protein × mineral interaction effect was observed for total glucagon-like peptide-1 (GLP-1TOTAL) incremental AUC (iAUC; P < 0·01), whereby MINERALS + AGGREG increased GLP-1TOTAL iAUC to a greater extent than AGGREG (1882 ± 603 v. 1550 ± 456 pmol·l−1·120 min, P < 0·01), but MINERALS + NATIVE did not meaningfully alter the GLP-1 iAUC compared with NATIVE (1669 ± 547 v. 1844 ± 550 pmol·l−1·120 min, P = 0·09). A protein × minerals interaction effect was also observed for gastric emptying half-life (P < 0·01) whereby MINERALS + NATIVE increased gastric emptying half-life compared with NATIVE (83 ± 14 v. 71 ± 8 min, P < 0·01), whereas no meaningful differences were observed between MINERALS + AGGREG v. AGGREG (P = 0·70). These did not result in any meaningful changes in energy intake (protein × minerals interaction, P = 0·06). These data suggest that the potential for Ca2+ to stimulate GLP-1 secretion at moderate protein doses may depend on protein form. This study was registered at clinicaltrials.gov (NCT04659902).

Background/Objectives: Retrograde access of the peroneal artery (PA) is considered technically challenging and at risk of bleeding. The aim of this multicentre retrospective study was to assess the safety, feasibility, and technical success of this access route for infrainguinal endovascular recanalizations. Methods: We retrospectively analyzed 186 consecutive patients treated over a 7-year period (May 2014–August 2021) who underwent endovascular recanalization of infra-inguinal lesions using a PA access route. In all cases, retrograde PA access was obtained following a failed attempt to cross the occlusion via the antegrade route. Results: Among the 186 patients, 120 were males (60.5%) and the mean age was 76.8 ± 10.7 years old (44–94 years). One hundred and thirteen patients (60.7%) suffered from chronic limb threatening ischemia (CLTI). All patients presented with chronic total occlusions (CTO) and a failed conventional antegrade recanalization attempt. Retrograde access was performed under angiographic guidance in 185 cases (99.5%). It was successfully established in 171 cases (91.9%). The total rate of retrograde puncture-related complications was 2.1% (two puncture site bleedings of which one necessitated fasciotomy and two cases of arteriovenous fistulas managed conservatively). The Major Adverse Event (MAE) rate at 30 days was 1.6% (3/186). Conclusions: Retrograde recanalization of challenging infra-inguinal lesions via PA is safe and effective in experienced hands.

Purpose This study investigated whether the respiratory phase during pleural puncture in CT-guided percutaneous transthoracic needle biopsy (PTNB) affects complications. Materials and Methods We conducted a retrospective review of 477 lung biopsy CT scans performed during free breathing. The respiratory phases during pleural puncture were determined based on the table position of the targeted nodule using CT scans obtained during free breathing. We compared the rates of complications among the inspiratory, mid-, and expiratory respiratory phases. Logistic regression analysis was performed to control confounding factors associated with pneumothorax. Results Among the 477 procedures, pleural puncture was performed during the expiratory phase in 227 (47.6%), during the mid-phase in 108 (22.6%), and during the inspiratory phase in 142 (29.8%). The incidence of pneumothorax was significantly lower in the expiratory puncture group (40/227, 17.6%; p = 0.035) and significantly higher in the mid-phase puncture group (31/108, 28.7%; p = 0.048). After controlling for confounding factors, expiratory-phase puncture was found to be an independent protective factor against pneumothorax (odds ratio = 0.571; 95% confidence interval = 0.360-0.906; p = 0.017). Conclusion Our findings suggest that pleural puncture during the expiratory phase may reduce the risk of pneumothorax during image guided PTNB. [ABSTRACT FROM AUTHOR]

The present study investigated the relationship between pre-procedural radial intima-media thickness (rIMT) and radial artery thrombosis (RAO) in patients undergoing angiography using a transradial approach (TRA). Patients (n = 90) who underwent cerebral or peripheral arterial angiography using TRA were included in the study. Ultrasonographic evaluation was performed before and 12 h after the procedure. Preoperative rIMT measurement was performed at the distal radial artery. Presence of radial artery occlusion was evaluated by ultrasonography after radial catheterization and revealed occlusive thrombus in the radial artery in 13 patients. rIMT was found to be statistically significantly higher in patients with thrombus (P <.05). When it was evaluated whether there was a correlation between age and rIMT, a positive significant correlation was found (P <.01). Our study suggests that increase of rIMT may be a risk factor for RAO in the intervention area. Before the procedure, ultrasound (US) assessment of the radial artery may be useful in determining the risk of occlusion. Thus, RAO-related technical risk factors (procedure time, number of punctures, sheath thickness, etc.) can be managed more carefully in patients having radial angiography. [ABSTRACT FROM AUTHOR]

Background & objective: Perioperative management of female patients undergoing breast surgery includes a big anesthetic task to adequately manage persistent postoperative pain and postoperative nausea and vomiting (PONV). Pectoral nerve blocks (PECS I and PECS II), while effective in managing postoperative pain, carry a risk of throacoacromial artery puncture with the lateral approach. We evaluated analgesic efficacy of medial approach to PECS I and PECS II blocks in female patients undergoing breast surgery under general anesthesia (GA). Methodology: This is a retrospective study of 116 female patients undergoing modified radical mastectomy that were divided into two groups. Group 1 patients received PECS block with general anesthesia and Group 2 patients received general anesthesia alone. Mean time to extubate, postoperative morphine consumption and PONV were evaluated up to 24 h. Results: Patients who received the PECS block required significantly less postoperative morphine immediately after and 12 h after surgery (P = 0.043 and P = 0.006, respectively). There was no significant difference in PONV between both groups in the first 24 h (P > 0.05). Time to extubation (TTE) was significantly less in Group 1 patients (P < 0.001). Conclusion: The medial approach of PECS I and II nerve block is effective and safe demonstrating reduced postoperative morphine requirement. [ABSTRACT FROM AUTHOR]

Objectives: The aim was to identify the factors related to inadequate hemostasis with five minutes of manual compression using the EXOSEAL vascular closure device (VCD), and to evaluate the optimal time to hemostasis (TTH). Methods: A total of 119 consecutive patients who underwent neuro-endovascular therapy via common femoral arterial puncture between February 2019 and August 2021 were included. These patients underwent hemostasis using an EXOSEAL with manual compression for five minutes. In this retrospective study, the 119 patients were divided into two groups: (1) achieved hemostasis with five minutes (n = 76); and (2) required more than five minutes to achieve hemostasis (n = 43, Add group). In both groups, patient's characteristics, endovascular procedures, and closure procedures were assessed. Results: On univariable analysis, activated clotting time (ACT), multiple antiplatelets, closure with an under-sized EXOSEAL VCD (U-VCD), endovascular procedure, and use of a 7Fr. VCD were significantly associated with additional compression (p < 0.05). On multivariate logistic regression analysis, the following three factors were found to be associated with additional compression: pre-closure ACT (adjusted OR, 0.136; 95% CI, 1.017–1.056; p < 0.001); multiple antithrombotics (adjusted OR, 12.843; 95% CI, 3.458–47.693; p < 0.001); and closure with a U-VCD (adjusted OR, 5.653; 95% CI, 1.751–18.151; p = 0.004). On the receiver-operating characteristic curve analysis for prediction of the need for additional compression, the cutoff point for pre-closure ACT was calculated to be 268 s. In the Add group, mean TTH was 9.8 ± 1.5 min. Conclusion: Multiple antiplatelets and closure with a U-VCD may increase the risk of insufficient hemostasis with five-minutes compression using an EXOSEAL VCD for femoral puncture sites if the pre-closure ACT is greater than 268 s. In these patients, mean TTH was 9.8 ± 1.5 min. [ABSTRACT FROM AUTHOR]

Introduction: Spinal angiography (SpAn) is the gold standard for diagnosis of spinal dural fistulas and arteriovenous malformations. A complete spinal angiogram necessitates the interrogation of the segmental arteries arising from the aorta at every level as well, the internal iliac; and median sacral arteries at the caudal end; and the cervical vasculature at the cranial end. SpAn has traditionally been performed with transfemoral arterial access and could be challenging. Of late, transradial arterial access has emerged as a popular alternative for endovascular surgical Neuroradiology (ESN) procedures including SpAn. However, there is paucity of the literature regarding transradial access for spinal angiography. Methods: After IRB approval, records and imaging were reviewed in a series of patients who underwent SpAn at our institution. Results: A total of nine spinal angiograms were performed via transradial access in a consecutive series of eight patients between July 2019 and December 2020 at our institution. Eight of these were diagnostic SpAn's, and one patient underwent SpAn with transradial approach for the treatment of a type I spinal dural arteriovenous fistula. No complications occurred during or subsequent to the procedures. Conclusion: SpAn can be successfully and safely accomplished via transradial access. This approach appears to provide a stable method for interventions, as well. [ABSTRACT FROM AUTHOR]

Background: Arterial punctures are a common procedure used to obtain blood samples for lab tests that guide treatment of neonatal patients. These punctures can be painful and have associated risks, emphasizing the importance of keeping attempts to a minimum. Purpose: The purpose of this quality improvement initiative was to determine whether using transillumination to visualize arteries before and while obtaining a blood sample would improve outcomes in neonatal patients. Methods: Quantitative data were collected pre- and postimplementation of education for the use of a transillumination device for arterial punctures on neonates in a level III neonatal intensive care unit (NICU). Outcomes followed included the success rate, average time to obtain a blood sample, and the average number of sticks to obtain a blood sample. Data were collected on 47 blood draw attempts in the control group (preimplementation) and 19 blood draw attempts in the experimental group (postimplementation). Results: A statistical analysis concluded that the use of the studied transillumination device does positively affect the incidence of successful blood draws, particularly for the novice NICU nurse. In addition, the average number of sticks to obtain a blood sample significantly decreased in the experimental group. Finally, the average time to obtain a blood sample using the device was not impacted in this study. Implications for Practice and Research: Use of a transillumination device does appear to result in improved outcomes for arterial punctures in neonatal patients. More research is needed to confirm these findings due to the small sample size of the study. [ABSTRACT FROM AUTHOR]

Background Device-related thrombosis (DRT) is a known complication to left atrial appendage closure (LAAC). The surface of a LAAC device should ideally have antithrombotic properties. The novel WATCHMAN FLX Pro (WFP) incorporates a fluoropolymer-coated fabric membrane designed to increase thromboresistance and facilitate endothelialization. Such features could potentially allow for a minimal post-procedural antithrombotic regimen. Radiopaque platinum markers at the device shoulders and a large 40 mm device are other novel features of the WFP. Case summary A 75-year-old man with atrial fibrillation was referred for LAAC due to prior subdural haemorrhage during direct-acting anticoagulation treatment. He underwent the first-in-human WFP implantation as part of the WATCHMAN FLX Pro CT study (NCT05567172). Computed tomography (CT) was used for pre-planning, and the procedure was performed under local analgesia guided by intracardiac echocardiography from the left atrium (LA) without any complications. Post-procedural antithrombotic treatment consisted of acetylsalicylic acid 75 mg/day only, and 45-day CT, transoesophageal echocardiography (TEE), and magnetic resonance imaging demonstrated optimal device position with complete LAAC. Hypoattenuated thickening (6 mm) appeared on the device as a smooth surface in continuity with the left atrial wall on CT and TEE. A specific magnetic resonance T1-weighted scan, used for visualization of fresh thrombus, suggested this to represent tissue ingrowth rather than thrombus. Discussion The advanced follow-up imaging protocol suggested a good WFP implantation result with signs of tissue ingrowth at 45 days. The added radiopaque markers facilitated optimal deployment, evaluation of device stability during tug test, and assessment of device protrusion into the LA. [ABSTRACT FROM AUTHOR]

Background: Currently, transcatheter aortic valve implantation (TAVI) is the standard procedure recommended for patients over 75 years of age with symptomatic aortic valve stenosis. Percutaneous transfemoral (TF) access is the main route used to perform the procedure. Among periprocedural complications, access-related ones are the most frequent, potentially leading to prolonged in-hospital stays and transfusions. Methods: We performed a retrospective analysis of prospectively collected data on consecutive patients undergoing TF-TAVI with the latest generation balloon-expandable transcatheter valve between 2013 and 2022. Results: A total of 600 patients were analyzed, differentiating the population between ultrasound-guided and blind common femoral artery puncture. Valve Academic Research Consortium 3 (VARC-3)criteria were used to report at 30 days and follow-up. In our propensity-matched comparison of the two groups, we found a strong reduction in access-related complications in the echo-guided group, particularly in terms of reduction of major and minor bleedings. We also found a significant trend in reduction of local complications, such as pseudoaneurysms, hematomas, arterio-venous fistulas, dissection of the femoral or iliac arteries, and stenosis. Conclusions: Although there is a lack of consensus on the role of ultrasound-guided puncture, we found better outcomes for patients having an echo-guided puncture of the main access, particularly with regard to access-related complications, early mobilization, and early discharge home.

Study Objective: To investigate diverse hysterectomy techniques to determine their influence on patient outcomes, including pain levels, sexual function, anxiety, and quality of life. Of particular focus is the comparison between vessel sealing and traditional suturing in abdominal, vaginal, and laparoscopic hysterectomies. This study is unique in its comprehensive evaluation, considering patient satisfaction, recommendation rates, recovery times, and various other aspects. Method: Our prospective cohort study adhered to ethical guidelines, involving a meticulous assessment of patients, including medical history, anxiety levels, pelvic pain, sexual function, and quality of life. Surgical methods were explained to patients, allowing them to actively participate in the decision-making process. Sociodemographic information was collected, and exclusion criteria were applied. Hysterectomy methods included total abdominal hysterectomy (TAH), laparoscopic hysterectomy (TLH), vaginal hysterectomy (VH), and a modified vaginal technique known as VH Mujas. Several parameters were recorded, including operation indications, uterine volume, hospital stay, operation duration, pre-operative and post-operative complications, and more. Results: In all groups, a statistically significant increase was found in pre-operative–post-operative FSFI sexual function values (p < 0.001). The patient's basal Beck Anxiety Scale scores significantly decreased following the decision for vaginal surgery, both in the VH and VH Mujas groups (p < 0.05). However, Beck Anxiety Scale scores at patients' initial assessments significantly increased following the decision for abdominal and laparoscopic surgery (p < 0.001). According to the results of the SF-36 quality of life assessment, an increase was observed in all post-operative quality of life parameters in patients who underwent surgery with different methods due to VH (p < 0.05). Conclusions: Our comprehensive comparison of hysterectomy techniques demonstrated that VH, particularly when utilizing the Mujas technique, outperforms other hysterectomy methods regarding patient safety and post-operative satisfaction but also offers the benefit of minimal invasiveness. Notably, this is reflected in improved quality of life, enhanced sexual function, lower pain scores, and favorable cosmetic results. The success of a hysterectomy procedure depends on precise indications, surgical planning, proper patient selection, and effective communication. This study emphasizes the significance of these factors in achieving optimal outcomes. The development of specialized vascular closure devices can further enhance the feasibility of vaginal hysterectomy, making it a preferable choice in gynecological surgery. The study contributes valuable insights into selecting the most suitable hysterectomy method for patients and optimizing their recovery. [ABSTRACT FROM AUTHOR]

Ultrasound plays a major role in neonatal/pediatric vascular access, both for venous access and for arterial access, not only just for the insertion of intravascular catheters, but also for many other issues related to this type of maneuver. This "global use of ultrasound" includes a systematic and consistent adoption of this technology for several steps of vascular access: (a) the pre-procedural assessment/evaluation of the vessels, (b) the ultrasound-guided puncture and cannulation of arteries and veins, (c) the real-time diagnosis of immediate, puncture-related complications, (d) the so-called "tip navigation" (i.e., real-time intra-procedural assessment of the direction and trajectory of the guidewire and/or of the catheter inside the vasculature), (e) the so-called "tip location" (i.e., intra-procedural or post-procedural assessment of the proper position of the tip of the catheter), and (f) the early diagnosis and/or management of most non-infective late complications. Conclusion: Therefore, any vascular access expert (nurse or physicians) should have documented competency in the use of ultrasound. This knowledge should include the use of ultrasound for assessment of vessels, for catheter insertion, for proper placement of the tip, and for real-time detection of complications. What is Known: • Ultrasound is obviously useful for vascular access procedures in neonates and children. What is New: • Recent evidence suggests that ultrasound is useful for many purposes in the field of vascular access (preprocedural scan, ultrasound-guided puncture, tip navigation, tip location, diagnosis of most non-infective complications). • Recent evidence also suggests that radiological methods no longer play any role in the insertion of vascular accesses in neonates and children.

Background: Blood donation is a safe process though reactions may still occur. We describe a rare vascular complication in a frequent donor, with improvements in the collection process aimed at avoiding future events. Methods: A 63‐year‐old woman presented with local pain and an apparent collection in the left arm 8 days after donation. Duplex ultrasound identified a superficial liquid collection and signs of arteriovenous fistula (AVF) between the cubital vein and an arterial branch. A computed tomography (CT)‐angio performed 1 day after ultrasound did not identify signs of AVF, followed by a new duplex which confirmed CT‐angio findings. It was assumed that a traumatic AVF evolved with spontaneous thrombosis. In the early follow‐up (18 days), a progressive regression of hematoma was observed without any sequelae. Results: Investigation showed a faster whole blood bag collection time (3 min; normal: 5–9 min), and the processed packed red blood cell had a brighter red color than usual. The donor reported local bleeding after needle withdrawal, not observed in previous donations and a bruise forming on the same day. No arterial puncture (AP) was noticed by the collection staff during the procedure. The staff was retrained and actions were taken focusing on more active surveillance of late reactions, highlighting the importance of post‐donation information by the donors, regardless of any adverse reaction observed, to detect late complications. Conclusion: We described an uncommon AP in a donor that was not identified, leading to an AVF that spontaneously thrombosed. [ABSTRACT FROM AUTHOR]

BACKGROUND: Femoral artery puncture is still the most used surgical approach. Because the operation requires local anaesthesia, the patient may not be able to exert full self-control, and their upper and lower limbs and trunk need to be constrained by a protection device. OBJECTIVE: To explore the safe application effect of a new type of anti-movement protection device for upper and lower extremities, shoulders and chest in patients undergoing interventional therapy via the femoral artery approach. METHODS: This is a prospective randomised controlled study. A total of 230 patients were randomly divided into two groups: the study group (n = 115) and the control group (n = 115). The time needed to implement the restraint operation and the loosening of the restraint device in the two groups was recorded, and the satisfaction of surgeons and nurses was investigated. RESULTS: The time needed to perform restraint operation in the study group was significantly less than that in the control group (4.06 ± 0.61 min vs. 7.01 ± 0.76 min, P < 0.05). The satisfaction of surgeons and nurses with the use of the new protective device was significantly better than that of the conventional restraint band (P < 0.05). CONCLUSION: The new anti-movement protection device for upper and lower limbs, shoulders and chest can conveniently and quickly achieve effective protection and braking of patients, ensure the safety of surgery and improve satisfaction.

There is evidence that healthcare can be executed differentially depending on the gender of patients, researchers, and clinicians. The aim was to analyze the possible existence of nursing gender differences in pain management produced by arterial puncture for blood gas analysis. A cross-sectional, multicenter study designed was conducted in Castilla-la Mancha (Spain). Variables of interest were collected from nurses in the public health system of a European region through a questionnaire. Data were collected for four months; the primary outcome was the use of any intervention to reduce pain and the explanatory variable was the nurse's gender. Bivariate analysis was carried out to assess associations between gender and pain-reducing interventions and a multivariate model was created with those factors that were relevant using logistic regression. A significantly higher proportion of men reported using some form of intervention (45% vs. 30%) and had more specific training (45.9% vs. 32.4%). The adjusted probability of using pain-reducing interventions by men was 71% higher than women. Thus, we found gender differences in the management of pain caused by arterial punctures performed by nurses as the main healthcare providers. [ABSTRACT FROM AUTHOR]

Ischemic limb lesions occasionally occur in neonates admitted to neonatal intensive care units. Known risk factors include the placement of arterial catheters, arterial punctures to obtain blood samples, and the use of vasoactive/vasopressor medications for hypotension. Prolonged peripheral tissue ischemia may result in serious complications, and successful management depends on early detection, proper assessment, and the institution of appropriate intervention. Currently, there is no standard approach for the management of peripheral tissue ischemia in extreme preterm infants. Topical nitroglycerine use is one of the promising options used to manage ischemic limb injuries in neonates, as demonstrated in several case reports. We report a case of digital ischemia in an extreme preterm infant with no clear risk factors except extreme prematurity, which recovered after topical nitroglycerine therapy. [ABSTRACT FROM AUTHOR]

Background: Postinterventional sonographic assessment of the femoral artery after transfemoral transcatheter aortic valve replacement (TF‐TAVR) has the potential to identify several pathologies. We investigated the incidence and risk factors of femoral vessel complications in a modern TAVR collective using postinterventional sonography. Methods: Between September 2017 and March 2022, 480 patients underwent TF‐TAVR with postinterventional femoral sonography at a single center. Clinical outcomes and adverse events were analyzed after the Valve Academic Research Consortium 3 (VARC‐3) criteria. Results: In this cohort (51.2% male; age 80 ± 7.5 years, median EuroSCORE II 3.7) 74.8% (n = 359) were implanted with a self‐expandable and 25.2% (n = 121) with a balloon‐expandable valve. The main access (valve‐delivery) was located right in 91.4% (n = 438), and the primary closure system was Proglide in 95% (n = 456). Vascular complications (VC) were observed in 29.16% (n = 140) of patients; 23.3% (n = 112) presented with minor‐ and 5.8% (n = 28) with major VC. Postinterventional femoral artery stenosis on the main access was observed in 9.8% (n = 47). Multivariable logistic regression analysis revealed female sex (p =.03, odds ratio [OR] 2.32, 95% confidence interval [CI] 1.09–4.89) and the number of used endovascular closure devices (p =.014, OR 0.11, 95%CI 0.02–0.64) as predictive factors for femoral artery stenosis. Conclusions: The incidence of postinterventional femoral artery stenosis following TF‐TAVR was higher than expected with a number of used closure devices and female sex being independent risk factors. Considering the continuous advance of TAVR in low‐risk patients with preserved physical activity, emphasis should be directed at the correct diagnosis and follow‐up of these complications.

Hemostatic devices are critical for managing emergent severe bleeding. With the increased use of anticoagulant therapy, there is a need for next-generation hemostats. We rationalized that a hemostat with an architecture designed to increase contact with blood, and engineered from a material that activates a distinct and undrugged coagulation pathway can address the emerging need. Inspired by lung alveolar architecture, here, we describe the engineering of a next-generation single-phase chitosan hemostat with a tortuous spherical microporous design that enables rapid blood absorption and concentrated platelets and fibrin microthrombi in localized regions, a phenomenon less observed with other classical hemostats without structural optimization. The interaction between blood components and the porous hemostat was further amplified based on the charged surface of chitosan. Contrary to the dogma that chitosan does not directly affect physiological clotting mechanism, the hemostat induced coagulation via a direct activation of platelet Toll-like receptor 2. Our engineered porous hemostat effectively stopped the bleeding from murine liver wounds, swine liver and carotid artery injuries, and the human radial artery puncture site within a few minutes with significantly reduced blood loss, even under the anticoagulant treatment. The integration of engineering design principles with an understanding of the molecular mechanisms can lead to hemostats with improved functions to address emerging medical needs.

This article discusses the use of whole-body perfusion (WBP) in neonatal aortic arch surgery as an alternative to the standard procedure of antegrade cerebral perfusion (ACP). The study compared the outcomes of patients who underwent surgery with either ACP or WBP. The results showed that patients in the WBP group had lower levels of complications, including neurological deficits, and required fewer blood transfusions. The use of WBP was found to be safe and feasible, with no significant vascular complications at the puncture site. [Extracted from the article]

This article, published in the Arab Journal of Interventional Radiology, discusses the use of a percutaneous sutured-mediated closure device called Perclose Pro Glide to manage iatrogenic carotid injury during central catheter insertion. The case presentation describes a 76-year-old male who experienced accidental carotid catheterization during the procedure. The authors utilized two percutaneous closure devices to close the carotid-jugular fistula, resulting in complete resolution of the fistula. The patient did not experience any immediate complications, and subsequent imaging showed excellent blood flow to the brain. The article highlights the effectiveness and safety of percutaneous arterial closure devices in treating injured vessels. [Extracted from the article]

This article provides an overview of vascular closure devices (VCDs) used in minimally invasive endovascular procedures. VCDs are alternatives to manual compression for achieving hemostasis postprocedure, and they have been shown to improve patient satisfaction and decrease time to discharge. However, there are concerns about complications and costs associated with VCDs, leading some clinicians to not use them. The article classifies VCDs into different categories based on their mechanisms of action, including suture-mediated, mechanical, sealant-based, stainless steel-based, and manual compression assistance devices. The article also discusses the indications, contraindications, and complications of VCDs, as well as strategies for preventing and managing these complications. [Extracted from the article]

Background: To explore the optimal dosage of heparin in peripheral arteriovenous automatic synchronous exchange transfusion therapy for neonatal hyperbilirubinemia. Methods: A total of 185 neonates received peripheral arteriovenous synchronous blood exchange transfusion for hyperbilirubinemia were enrolled from pediatric department of the Ganzhou People's Hospital between January 2018 and June 2020, which were randomly divided into four groups. On the basis of exchange transfusion, different dose of heparin was pumping at the bleeding site of artery (A: no heparin; B: 100 U/h heparin; C: 200 U/h heparin; D: 300 U/h heparin). The indexes of exchange transfusion efficacy, including total bilirubin conversion rate, indirect bilirubin conversion rate, hemoglobin concentration, the platelet number and APTT value was measured before and after therapy. The sites of artery puncture, the sites and rate of vascular occlusion were counted and analyzed. Results: There was no significant difference for total bilirubin conversion rate, indirect bilirubin conversion rate, hemoglobin concentration platelet number and APTT value before and after exchange transfusion between the four groups (P >0.05). In addition, there was no statistical significance in artery puncture sites between the four groups (P > 0.05). Significant difference in total rate of vascular occlusion and rate of radial artery occlusion were found between the four groups (P< 0.05). Conclusion: Different dose of heparin using in peripheral arteriovenous synchronous blood exchange transfusion did not affect the therapeutic effect or coagulation function of patients, but could reduce the rate of occlusion depending by the site of arterial puncture.

Transradial access is an important tool for many neuroendovascular procedures. Occlusion of the radial or ulnar artery is not uncommon after transradial or transulnar access and can present a challenge for patients requiring repeat angiography. Between March 2022 and June 2023, patients undergoing transradial or transulnar angiography who were found to have a radial artery occlusion or ulnar artery occlusion were identified. Repeat catheterization of the occluded artery was attempted using a 21-gauge single wall puncture needle and a 0.021-inch wire to traverse the occlusion and insert a 23-cm sheath into the brachial artery. A total of 25 patients undergoing 26 angiograms during the study period were found to have a radial artery occlusion or ulnar artery occlusion. Successful repeat catheterization of the occluded artery was achieved in 21 of 26 cases (80.7%). Outer diameter sheath size ranged from 5 Fr (0.0655 inch) to 8 Fr (0.1048 inch). No access complications were encountered. Number of prior angiograms, time since prior angiogram, and prior angiogram procedure time were associated with lower likelihood of successful access. Transradial or transulnar neuroangiography through an occluded radial or ulnar artery is safe and feasible by traversing the occlusion into the brachial artery with a 23-cm sheath. Repeat catheterization is most successful in patients with an arterial occlusion <6 months old. This technique is important in patients who have limited options for arterial access, avoiding access site complications inherent in transfemoral access, and in patients who specifically require radial or ulnar artery access.

Atrial fibrillation (AF) is the most commonly observed arrhythmia in the world and its prevalence increases with age. The main and most severe complication of AF is ischemic stroke. Oral anticoagulation (OAC) therapy is the standard of care for stroke prevention in the high risk population. Initiation of this treatment is associated with a substantial risk of bleeding complications. Moreover, there is a group of patients who cannot tolerate OAC. In patients with AF the left atrial appendage (LAA) is the main source of thrombus formation. Percutaneous left atrial appendage closure (LAAC) has become an important non-pharmacological intervention for stroke prevention in patients with non-valvular AF. The procedure aims to reduce the risk of thromboembolism without increasing the risk of bleeding. Over the last few years, the safety and long-term efficacy of the procedure in specific populations have increased and more patients are being treated. The Watchman device is the most studied device in this field. Randomized controlled trials demonstrated non-inferiority of percutaneous left atrial appendage closure using the WATCHMAN 2.5 device to OAC (Boston Scientific, Marlborough, MA, USA). The new generation device, WATCHMAN FLX, was introduced and its use was associated with fewer safety events and a higher success rate of effective appendage closure. Nevertheless, several unsolved problems remain, including device-related thrombosis, the post-LAAC antithrombotic regimen, and peri-device leakage. This review will focus on LAAC with the Watchman device for stroke prevention in AF patients. Current status, available literature, clinical safety and efficacy will be summarized.
