Background: The neutrophil-to-lymphocyte ratio (NLR) is an independent predictor of the severity of coronary heart disease and COVID-19. This study aims to assess the predictive ability of the NLR in patients with in-stent restenosis after COVID-19. Materials and Methods: a cross-sectional study included 931 patients who underwent repeated myocardial revascularization between May 2020 and May 2023. The 420 patients of the main group had in-stent restenosis, of which 162 patients had COVID-19 previously. The control group included 511 patients without stent restenosis (107 patients had COVID-19 previously). All reported events were verified by hospital electronic records from the Complex Medical Information System. Results: The mean values of the NLR were 2.51 and 2.68 in the study groups, respectively. A statistically significant positive relationship in both groups was found between the NLR and troponin, D-dimer, C-reactive protein, creatinine, ALT, and AST. A statistically significant positive relationship was found between NLR and myocardial infarction (MI) in patients of both groups (p = 0.004; p < 0.001, respectively) and a negative relationship with the ejection fraction (p = 0.001; p < 0.036, respectively). An evaluation of the predictive ability of the clinical and laboratory predictors of recurrent myocardial infarction shows a high degree of utility of this model. The area under the ROC curve for AUC for NLR was 0.664 with 95% CI from 0.627 to 0.700 (p < 0.001). Conclusions: NLR is one of the significant factors for predicting the development of adverse outcomes in patients with revascularized myocardium after COVID-19. [ABSTRACT FROM AUTHOR]

Background: Fibrosing mediastinitis (FM) is a rare yet fatal condition, caused by different triggers and frequently culminating in the obstruction of the pulmonary vasculature and airways, often leading to pulmonary hypertension and right heart failure. Percutaneous transluminal pulmonary venoplasty (PTPV) is an emerging treatment for pulmonary vein stenosis (PVS) caused by FM. Our previous study showed as high as 24% of in-stent restenosis (ISR) in FM. However, the predictors of ISR are elusive. Objectives: We sought to identify the predictors of ISR in patients with PVS caused by extraluminal compression due to FM. Methods: We retrospectively enrolled patients with PVS-FM who underwent PTPV between July 1, 2018, and December 31, 2022. According to ISR status, patients were divided into two groups: the ISR group and the non-ISR group. Baseline characteristics (demographics and lesions) and procedure-related information were abstracted from patient records and analyzed. Univariate and multivariate analyses were performed to determine the predictors of ISR. Results: A total of 142 stents were implanted in 134 PVs of 65 patients with PVS-FM. Over a median follow-up of 6.6 (3.4–15.7) months, 61 of 134 PVs suffered from ISR. Multivariate analysis demonstrated a significantly lower risk of ISR in PVs with a larger reference vessel diameter (RVD) (odds ratio (OR): 0.79; 95% confidence interval [CI]: 0.64 to 0.98; P = 0.032), and stenosis of the corresponding pulmonary artery (Cor-PA) independently increased the risk of restenosis (OR: 3.41; 95% CI: 1.31 to 8.86; P = 0.012). The cumulative ISR was 6.3%, 21.4%, and 39.2% at the 3-, 6-, and 12-month follow-up, respectively. Conclusion: ISR is very high in PVS-FM, which is independently associated with RVD and Cor-PA stenosis. Trail Registration: Chinese Clinical Trials Register; No.: ChiCTR2000033153.

Endovascular options for the treatment of basilar apex aneurysms (BAAs) are heterogeneous, and evidence is limited to retrospective cohorts and case series. We seek to evaluate the efficacy and complications associated with various endovascular treatment methods of BAAs. Systematic review of PubMed, Embase, and Web of Science adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Retrospective and prospective studies evaluating endovascular treatment of BAAs between January 2010 and July 2024 were included. Relevant information including occlusion rates, aneurysm recurrence, retreatment rates, and complications were subjected to meta-analysis. Fifteen studies with 1049 BAAs were included. The median aneurysm diameter was 8.5 mm (range, 4.6–19.75), with a median follow-up of 33.7 months (range, 6.0–117.6). Residual aneurysm filling occurred in 24% after primary coiling (95% CI = 0.16–0.32), 25% after single stent-assisted coiling (s-SAC; 95% CI = 0.04–0.46), 25% after Y-stents (95% CI = 0.12–0.37), and 23% after flow diverter stent (FDS; 95% CI = 0.11–0.35). Recurrence rates were high for primary coiling (27%, 95% CI = 0.18–0.36) and s-SAC (19%, 95% CI = 0.13–0.26), but significantly lower for Y-stents (9%, 95% CI = 0.03–0.15) and FDS (4%, 95% CI = −0.04–0.11). Retreatment rates were 19% for primary coiling (95% CI = 0.12–0.26), 17% for s-SAC (95% CI = 0.07–0.27), 5% for Y-stents (95% CI = −0.03–0.12), and 13% for FDS (95% CI = −0.01–0.27). Meta-regression indicated larger aneurysms had higher complication rates (P = 0.02). Thromboembolic events were most frequent with FDS and Y-stents(12%). Occlusion rates were similar across treatments, but recurrence rates were significantly lower after Y-stents and FDS compared to primary coiling, although they carried a higher number of thromboembolic complications.

For symptomatic stenosis in the middle cerebral artery (MCA), intracranial angioplasty and stenting are frequently employed. However, limited data exist regarding their long-term impact. Our study demonstrates the long-term advantages in preventing ischemic events through a 5-year follow-up period. A set of 41 individuals with symptomatic stenosis in the MCA who underwent angioplasty or stenting procedures between October 2004 and April 2018 at various hospitals in Southwest China were prospectively enrolled in the study. The rates of successful revascularization, complications, imaging observations, and clinical outcomes were systematically assessed. A total of 41 individuals successfully underwent stenting, respectively. After stenting, the extent of stenosis was decreased from 71.8% (56–87.8%) to 24.9% (0–45%). The mean follow-up period is 36.9 ± 13.68 months (range, 11–67 months). There was no deterioration of neurological function or a new ischemic event. A DSA or CT angiography was conducted after the procedure and demonstrated no in-stent restenosis. No patient experienced restenosis below 50% during the mean follow-up period. The morbidity and mortality rates of the case series were 7.3% and 2.4%, respectively. In the treatment of symptomatic MCA atherosclerotic stenoses, intracranial angioplasty and stenting are demonstrated to be technically feasible and safe. Its early and long-term efficacy on ischemic event prevention is acceptable, with a reduced level of restenosis, although the representative sample is tiny. [ABSTRACT FROM AUTHOR]

Intrahepatic cholangiocarcinoma (iCCA) is the second most common malignant primary liver cancer. iCCA may develop on an underlying chronic liver disease and its incidence is growing in relation with the epidemics of obesity and metabolic diseases. In contrast, perihilar cholangiocarcinoma (pCCA) may follow a history of chronic inflammatory diseases of the biliary tract. The initial management of CCAs is often complex and requires multidisciplinary expertise. The French Association for the Study of the Liver wished to organize guidelines in order to summarize the best evidence available about several key points in iCCA and pCCA. These guidelines have been elaborated based on the level of evidence available in the literature and each recommendation has been analysed, discussed and voted by the panel of experts. They describe the epidemiology of CCA as well as how patients with iCCA or pCCA should be managed from diagnosis to treatment. The most recent developments of personalized medicine and use of targeted therapies are also highlighted. [ABSTRACT FROM AUTHOR]

A four-year-old spayed female Shiba Inu dog weighing 6.1 kg presented with ascites. Cor triatriatum dexter (CTD) without any other concurrent cardiovascular anomalies was diagnosed using echocardiography. The ostium of the abnormal membrane dividing the right atrium into two abnormal chambers was surgically excised under cardiopulmonary bypass. All clinical abnormalities were resolved after surgery. However, seven months later, ascites and CTD recurred. A balloon-expandable stent was placed at the site of recurrence, which improved caudal venous return to the right ventricle. After the second procedure, ascites were resolved, and the dog remained asymptomatic for 18 months without complications. There are previous reports of successful surgical resection of the CTD and of stenting in recurrent CTD following balloon dilation in dogs. However, to the authors' knowledge, no previous reports have described recurrent CTD in dogs after surgical resection of the CTD. In this case, as with recurrent CTD following balloon dilation, stent placement at the site of the CTD can be a viable treatment option when the abnormal membrane recurs. [ABSTRACT FROM AUTHOR]

The long term benefit of carotid angioplasty and stenting (CAS) can be reduced by recurrent stroke related to in stent re-stenosis (ISR). An individualised predictive tool is needed to identify ISR events. A nomogram for individual risk assessment of ISR ≥ 70% after CAS is proposed. A national observational, prospective, multicentre registry was conducted between January 2015 and December 2020. Cohorts of patients with symptomatic or asymptomatic severe carotid stenosis who underwent CAS with a follow up of at least one year after CAS were included. Duplex ultrasound was used to assess in stent re-stenosis. Pre-operative factors were compared between the non-ISR and ISR groups. Kaplan–Meier and Cox regression were used for variable selection. The nomogram was formulated and validated by concordance indices and calibration curves. An in stent re-stenosis risk table was generated for risk stratification. A total of 354 patients were included in the analysis. The ISR rate of ≥ 70% was 7.6% (n = 27). Peripheral arterial disease (hazard ratio [HR] 3.18, 95% confidence interval [CI] 1.23 – 8.24, p =.017), anterior communicating artery absence (HR 3.38, 95% CI 1.27 – 8.94, p =.016), diabetes mellitus (HR 3.34, 95% CI 1.21 – 9.26, p =.020), female sex (HR 2.99, 95% CI 1.04 – 8.60, p =.041), and pre-procedure pathological ultrasound vasoreactivity (HR 3.87, 95% CI 1.43 –10.50, p =.008), as independent risk factors for ISR of ≥ 70%, were included in the nomogram. The concordance index at 12 and 24 months was 0.83. In low risk groups, ISR of ≥ 70% occurred in 4.8% of patients during follow up compared with 56.2% of patients in the high risk groups (p <.001). The nomogram and risk evaluation score have good predictive ability for ISR. They can be used as practical clinical tools for individualised risk assessment. [ABSTRACT FROM AUTHOR]

Spontaneous carotid artery dissections (sCADs) are the common cause of stroke in middle-aged and young people. There is still a lack of clinical classification to guide the management of sCAD. We reviewed our experience with 179 patients with sCAD and proposed a new classification for sCAD with prognostic and therapeutic significance. This is a retrospective review of prospectively collected data from June 2018 to June 2023 of patients with sCAD treated at a large tertiary academic institution in an urban city in China. Based on imaging results, we categorize sCAD into four types: type Ⅰ, intramural hematoma or dissection with <70% luminal narrowing; type Ⅱ, intramural hematoma or dissection with ≥70% luminal narrowing; type Ⅲ, dissecting aneurysm; type ⅣA, extracranial carotid artery occlusion; and type ⅣB, tandem occlusion. We compared the clinical data and prognostic outcomes among various types of sCADs. A total of 179 patients and 197 dissected arteries met the inclusion criteria. The mean age of the 179 patients with sCAD was 49.5 years, 78% were male, and 18 patients (10%) had bilateral sCAD. According to our classification, there were 56 type Ⅰ (28.4%), 50 type Ⅱ (25.4%), 60 type Ⅲ (30.5%), and 31 type Ⅳ (15.7%) dissections. During a mean hospitalization length of 11.4 ± 47.0 days, there were nine recurrent strokes (4.6%) after medical treatment, two type Ⅲ dissections (1.0%), seven type Ⅳ dissections (3.6%), all ipsilateral, and one death. Overall, there were seven (3.6%, 1 type Ⅰ dissection, 3 type Ⅱ dissections, 2 type Ⅲ dissections, and 1 type Ⅳ dissection) recurrent strokes and three (1.5%, all type Ⅲ dissections) recurrent transient ischemic attacks in patients treated with just medical therapy during the follow-up period, all ipsilateral, with a mean follow-up of 26 months (range, 3-59 months). These patients did not undergo further intervention due to the high difficulty associated with endovascular treatment (EVT) or the mild nature of recurrent cerebral ischemic symptoms. Twenty-nine type I dissections (51.8%) were completely recanalized after antithrombotic therapy. A total of 19 type II dissections (38%) and 44 type III dissections (73%) received EVT for persistent flow-limited dissections, enlargement of dissecting aneurysms, or aggravation of neurological symptoms despite antithrombotic therapy. Type Ⅳ dissections are more likely to lead to the occurrence of ischemic stroke and presented with more severe symptoms. Eight type IVB dissections (33%) received acute phase intervention due to distal thromboembolism or aggravation of neurological symptoms after medical treatment. In terms of cerebral ischemic events and mortality, there were no statistically significant differences among the four types of sCAD (all P >.05). Favorable outcome was achieved in 168 patients (93.9%). This study proposed a novel and more comprehensive classification method and the modern management strategy for sCAD. Antithrombotic therapy is beneficial to reduce the risk of recurrent stroke for stable sCAD. Non-emergent EVT can be an alternative therapeutic approach for patients who meet indications as in type II to IVA dissections. Urgent procedure with neurovascular intervention is necessary for some type IVB dissections. The short-term results of EVT for sCAD are encouraging, and long-term device-related and functional outcomes should undergo further research. [ABSTRACT FROM AUTHOR]

Objectives: While methods of endovascular carotid artery stenting have improved over time, concerns surrounding the safety and efficacy of stenting for blunt carotid injury (BCI) remain. This study aims to present our approach to carotid artery stenting (CAS) by incorporating new technologies such as flow-diverting stents and circuits. Methods: There is no robust evidence to support routine carotid artery stenting; however, there are several therapeutic options and approaches for treating BCI that currently require an individualized approach. Endovascular stenting and specific stent selection are largely dictated by the disease process the surgeon intends to treat. We will discuss patient selection, medical management, and the most common revascularization techniques, including transfemoral stenting, trans-carotid arterial revascularization using flow reversal, and stent-assisting coiling. Results: It must be stressed that endovascular intervention is not an alternative to or preclusive of antithrombotic or anticoagulant therapy. In the setting of BCI, transfemoral CAS is most appropriate in patients who are symptomatic, have a rapidly progressing or large lesion, and do not have a soft thrombus present due to risk of embolism. Unlike transfemoral CAS, TCAR offers an elegant solution for embolic protection when patients have a soft thrombus present. In the case of a large pseudoaneurysm, we perform stent-assisted coiling. Conclusions: We practice selective endovascular intervention, stenting lesions that are flow-limiting or have large or rapidly expanding pseudoaneurysms, and only in patients for whom anticoagulation and antiplatelet agents are not contraindicated. As technology and investigation progress, the concerns regarding the safety and the role of endovascular intervention in the treatment of BCI will be more clearly defined. [ABSTRACT FROM AUTHOR]

Based on community-based nutrition recording and reporting data (e-PPGBM), the stunting rate in the working area of the Mungkid Health Center in 2023 is 15.2%. Meanwhile, based on the 2023 Indonesia Nutrition Status Survey, the stunting rate in Magelang Regency is 28.2%. One of the factors that affect the stunting rate is the proper anthropometric measurement. This study aims to find out how the knowledge and skills of posyandu cadres in the working area of the Mungkid Health Center in conducting anthropometric measurements. It is a descriptive research carried out at the posyandu in the working area of the Mungkid Health Center, in December 2023. The research population is all posyandu cadres totaling 743 people, using Slovin's calculations, the number of subjects was 88 people who were selected by non-probability sampling. The characteristics of the respondents included age, education, length of cadre and anthropometric training. The level of knowledge is assessed through a questionnaire, and skills are assessed based on 7 indicators, namely weight measurement, body length, installing a microtoise, height measurement, Lila, head circumference and filling out the KMS book. Of the 88 subjects, 45.5% of the respondents were in the age range of 41-50 years, 60.2% had high school level education, 45.5% had been a cadre in the range of 1-5 years, and 62.5% had never received formal anthropometric training. For the level of knowledge with good value 40.9%. Respondents who were skilled in weight measurement 77.3%, installing microtoise 90.9%, height measurement 47.7%, body length measurement 39.7%, lila and head circumference 38.6%, and filling KMS book 43.2%. The chi square analysis has a p value of <0.05 which means that there is a relationship between anthropometric training of cadres and the ability of anthropometric measurement skills, especially in measuring body length and height as a reference for stunting. The picture of cadres who have not received training and skills in some anthropometric measurements is quite low. Training and mentoring of cadres by trained health center staff are needed.

Introduction Deep vein thrombosis (DVT) poses a complex challenge and often leads to postthrombotic syndrome (PTS), a debilitating complication. The emergence of venous stents offers a potential preventive avenue against this complication. This study aimed to provide consensus recommendations on the use of venous stent for DVT. Materials and Methods From June to July 2023, 20 internal medicine, angiology and vascular surgery, and vascular and interventional radiology experts were involved in the Delphi process. Thirty-one recommendations, categorized into three thematic areas, were rigorously evaluated: indications for stent use, stent selection and placement, and monitoring and prevention of complications. Agreement was evaluated using a Likert scale, with consensus defined as agreement by two-thirds of the participants. Results Consensus was reached for 23 (74.2%) of 31 recommendations. The agreement was centered on considerations, such as stent placement in specific acute DVT scenarios, emphasizing pivotal stent characteristics. However, there were divergences in the recommended stent length to prevent migration and stent characteristics based on iliocaval bifurcation morphology. Notably, there was no consensus on whether patients with DVT caused by a major transient risk factor need more than 3 months of anticoagulation therapy or whether aspirin should be added to anticoagulant treatment after venous stenting. Conclusions These consensus recommendations offer practical insights into optimizing venous stent use to prevent PTS in DVT patients. Addressing the critical aspects of stent selection, placement, and postprocedural care, these recommendations contribute to clinical decision-making. The identified divergences underscore the importance of consensus and thus indicate the need for further investigation. [ABSTRACT FROM AUTHOR]

Central venous occlusion (CVO) or stenosis (CVS) is a common complication of long-term hemodialysis catheters. Endovascular intervention, primarily balloon angioplasty and occasionally stent placement, is the primary approach for managing CVS/CVO lesions. The presence of a filter within the inferior vena cava (IVC) lumen makes recanalization of the IVC more challenging. Here we present a complex case of a 47-year-old female with end-stage kidney disease (ESKD), systemic lupus erythematosus, and recurrent deep venous thrombosis, necessitating an IVC filter, who became catheter-dependent via the right femoral vein and presented with total IVC occlusion below the filter. The occlusion was managed successfully with sequential angioplasty and stenting of the stenotic lesions. This intervention restored venous flow through the IVC into the right atrium and maintained dialysis access through the catheter. This case underscores the complexity of managing CVS/CVO in dialysis patients, especially with the presence of filters within the vascular dialysis conduit.

Abstract Background Fibrosing mediastinitis (FM) is a rare yet fatal condition, caused by different triggers and frequently culminating in the obstruction of the pulmonary vasculature and airways, often leading to pulmonary hypertension and right heart failure. Percutaneous transluminal pulmonary venoplasty (PTPV) is an emerging treatment for pulmonary vein stenosis (PVS) caused by FM. Our previous study showed as high as 24% of in-stent restenosis (ISR) in FM. However, the predictors of ISR are elusive. Objectives We sought to identify the predictors of ISR in patients with PVS caused by extraluminal compression due to FM. Methods We retrospectively enrolled patients with PVS-FM who underwent PTPV between July 1, 2018, and December 31, 2022. According to ISR status, patients were divided into two groups: the ISR group and the non-ISR group. Baseline characteristics (demographics and lesions) and procedure-related information were abstracted from patient records and analyzed. Univariate and multivariate analyses were performed to determine the predictors of ISR. Results A total of 142 stents were implanted in 134 PVs of 65 patients with PVS-FM. Over a median follow-up of 6.6 (3.4–15.7) months, 61 of 134 PVs suffered from ISR. Multivariate analysis demonstrated a significantly lower risk of ISR in PVs with a larger reference vessel diameter (RVD) (odds ratio (OR): 0.79; 95% confidence interval [CI]: 0.64 to 0.98; P = 0.032), and stenosis of the corresponding pulmonary artery (Cor-PA) independently increased the risk of restenosis (OR: 3.41; 95% CI: 1.31 to 8.86; P = 0.012). The cumulative ISR was 6.3%, 21.4%, and 39.2% at the 3-, 6-, and 12-month follow-up, respectively. Conclusion ISR is very high in PVS-FM, which is independently associated with RVD and Cor-PA stenosis. Trail Registration Chinese Clinical Trials Register; No.: ChiCTR2000033153.

ObjectiveSignificant regional variation is known with multiple surgical procedures. This study describes regional variation in carotid revascularization within the Vascular Quality Initiative (VQI).MethodsData from the VQI carotid endarterectomy (CEA) and carotid artery stenting (CAS) databases from 2016 to 2021 were used. Nineteen geographic VQI regions were divided into three tertiles based on the average annual volume of carotid procedures performed per region (low-volume: 956 cases [range, 144-1382]; medium-volume: 1533 cases [range, 1432-1589]; and high-volume: 1845 cases [range, 1642-2059]). Patients' characteristics, indications for carotid revascularization, practice patterns, and outcomes (perioperative and 1-year stroke/death) of different revascularization techniques were compared between these regional groups. Regression models that adjust for known risk factors and allow for random effects at the center level were used.ResultsCEA was the most common revascularization procedure (>60%) across all regional groups. Significant regional variation was observed in the practice of CEA such as variability in the use of shunting, drain placement, stump pressure and electroencephalogram monitoring, intraoperative protamine, and patch angioplasty. For transfemoral CAS, high-volume regions had a higher proportion of asymptomatic patients with

The optimal approach for supravalvar right ventricular outflow tract obstruction(RVOTO) after arterial switch operation(ASO) is unclear. The results of percutaneous balloon dilatation have been variable. We report the results of simultaneous double balloon dilation for RVOTO after ASO. Sixteen patients (1.3(0.7–3.8) years; 9.8(8.1–15.1) kgs underwent the procedure at 14(8–44.5) months after ASO. Salient technical features included placement of balloons over stiff guide-wires positioned in both branch pulmonary arteries to enable dilation of the distal-most main pulmonary artery (MPA) with high inflation pressures (~ 12–14 atmospheres) and short inflation-deflation cycles. Effective balloon size was based on the PA annulus or MPA distal to the narrowing. The final balloon: narrowest segment diameter ratio was 2.7. Following dilation, the right ventricle to systemic systolic pressure ratio decreased from 0.9 ± 0.18 to 0.52 ± 0.16 (p < 0.001) and mean RVOT gradient from 78 ± 18 to 34 ± 13.9 mmHg (p < 0.001). Narrowest diameter improved from 5.4 ± 2.2 to 9.2 ± 2.2 mm. There were no major complications. Two patients with inadequate relief (final RV-systemic ratios: 1.03 and 0.7) were referred for surgery. At median follow up of 9 months, IQR 7–22, range 5–73, others are free of re interventions with median RVOT gradient of 42, IQR 27–49, range 21–55 mmHg. The immediate and short-term follow up results of double balloon dilatation for supravalvar RVOTO is encouraging and may avoid the need for repeat surgery in the majority of patients. Further follow up is needed to determine the long-term durability of the results. [ABSTRACT FROM AUTHOR]

Superior vena cava obstruction is caused by a blockage in its blood flow; one of its few causes can be device related. This case follows a patient presented with superior vena cava obstruction following a septal cardiac implant. Endovascular intervention has been associated with more rapid, complete symptom relief and lower complication rates. The use of stenting as first-line therapy has gathered popularity to become standard practice in the past 2 decades. This paper illustrates a successful recanalization with penetrating diagnostic catheter, followed with percutaneous transluminal angioplasty stenting in order to preserve the patency superior vena cava.

Introduction: Vertebral artery (VA) ostial stenosis is notoriously difficult to treat using bare-metal stents owing to high rates of restenosis and stent kinking and breakage. We investigated the safety and effectiveness of treatment with a drug-eluting, balloon-expandable coronary stent (Resolute Onyx, Medtronic). Methods: Our prospectively maintained database was retrospectively searched for consecutive patients diagnosed with VA ostial stenosis who underwent Resolute Onyx stenting with/without angioplasty between January 1, 2015 and January 1, 2022. Patient demographics and clinical and radiographic presentations were recorded. Occlusion location, stenosis severity, contralateral disease, devices used, and intraprocedural and postprocedural complications were noted. Outcomes were assessed based on new or recurrent stroke, transient ischemic attack (TIA), or intracranial hemorrhage (ICH). Patients were followed up clinically and with radiographic imaging for in-stent stenosis. Results: Twenty-six patients were included in our study (21 men [80.8%]; mean age 70.3 ± 9.8 years). Symptomatic patients presented with TIA (11/26, 42.3%) and stroke (10/26; 38.5%). Mean stenosis in the study cohort was 74.9 ± 13.0%. One (3.8%) intraprocedural complication was encountered whereby the stent failed to open despite several attempts and was exchanged with a new one without issues. No in-hospital postprocedure stroke, TIA, or mortality was reported. During a mean 16.2 ± 13.6 months' follow up, two patients developed symptomatic in-stent restenosis that was treated with balloon angioplasty. Conclusions: We report the first case series of Resolute Onyx drug-eluting stenting including 30-day postprocedure stroke/TIA rates and clinical/radiographic follow up and demonstrate safe and effective treatment of symptomatic and asymptomatic VA ostial stenosis.

The therapeutic possibilities of endoscopy have rapidly increased in the last decades and now allow organ-sparing treatment of early upper gastrointestinal malignancy as well as an increasing number of options for symptom palliation. This review contains an overview of the interventional endoscopic procedures in upper gastrointestinal malignancies. It describes endoscopic treatment of early oesophageal and gastric cancers, and the palliative options in managing dysphagia and gastric outlet obstruction. It also provides an overview of the therapeutic possibilities of biliary endoscopy, such as retrograde stenting and radiofrequency biliary ablation. Endoscopic ultrasound-guided therapeutic options are discussed, including biliary drainage, gastrojejunostomy and coeliac axis block. To aid in clinical decision making, the procedures are described in the context of their indication, efficacy, risks and limitations. • Endoscopy now offers curative treatments for early oesophageal and gastric cancer. • Interventional endoscopy can offer effective symptom palliation for dysphagia, pain and jaundice. • Duodenal stents and EUS-guided interventions provide effective palliation in gastric obstruction.

Most surgeons employ an endovascular-first approach to the treatment of peripheral arterial disease (PAD), but controversy remains regarding the ideal interventions for the management of isolated popliteal artery disease (IPAD). Indeed, there are a paucity of data that compare outcomes of popliteal stents vs other peripheral vascular interventions (PVIs). The goal of this study was to evaluate outcomes of PVIs in IPAD. The Vascular Study Group of New England database was queried for all IPAD PVIs performed for atherosclerotic occlusive disease from 2010 to 2021. Those with at least 1 year of follow-up data available were included for analysis. The primary endpoint was 1-year freedom from a composite target lesion (TL) treatment failure that included restenosis >50% on duplex, reintervention, or ipsilateral major amputation. We included 689 procedures performed on 634 patients. Of these, 250 (36.3%) were treated with plain balloons (POBA), 215 (31.2%) had stents, 170 (24.7%) had special balloons (drug-coated, cutting, or lithotripsy), and 54 (7.8%) atherectomies were performed. Stent placement was associated with lower freedom from TL treatment failure (72.6%) than special balloon (81.2%; P =.048) and atherectomy (88.9%; P =.012), but not POBA (76.8%; P =.293). On multivariable logistic regression, stents (odds ratio, 0.637; P =.021) and preoperative P2Y12 inhibitor therapy (odds ratio, 0.683; P =.048) were both associated with lower freedom from intervention failure. Popliteal stent placement is associated with a higher rate of TL treatment failure at 1 year when compared with other PVIs including special balloon angioplasty and atherectomy, but not POBA, and should therefore be avoided in favor of special balloons or atherectomy whenever feasible.

Objective: To assess the complex management of arterial anomalies in Vascular Ehlers-Danlos Syndrome (vEDS). Methods: We report the case of a 34-year-old male, diagnosed with vEDS, who presented with acute intraperitoneal hemorrhage caused by the rupture of a splenic artery aneurysm, treated in emergency with coil embolization and splenectomy. Computed Tomography (CT) scan showed the concomitant presence of right renal artery (RRA) and common hepatic artery (CHA) aneurysms. Results: Both aneurysms were conservatively managed and the patient went through serial CT imaging. After 3 months, rapid regression of the vascular abnormalities led to complete disappearing of RRA and CHA aneurysms, confirmed at 24-month imaging follow-up. In the same time span, two pseudoaneurysms developed in other sites used for transarterial access, requiring two secondary interventions. The present case emphasizes the unpredictability of disease's evolution and arterial complications in vEDS. Conservative management of complex lesions such as visceral artery aneurysms, which in this case resulted to be the best strategy, avoided the risks associated with surgical intervention in such fragile tissues. The reported complications underline that operative indications should be carefully weighed in these patients. [ABSTRACT FROM AUTHOR]

Introduction: Patients presenting with large bowel obstruction (LBO) frequently undergo emergency surgery that is associated with significant morbidity. In malignant LBO, endoscopic approaches with placement is a self-expanding metal stent (SEMS), have been proposed to prevent emergency surgery and act as a bridge to an elective procedure—with the intention of avoiding a stoma and reducing morbidity. This systematic review aims to assess the quality and outcomes of data available on the use of SEMS in benign causes of colonic obstruction. Methods: This systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and the protocol was registered on Prospero (ID: CRD42021239363). PUBMED, MEDLINE, HMIC, CINAHL, AMED, EMBASE, APA and Cochrane databases were searched. Studies were assessed for quality utilising the MINORS criteria. Pooled odds ratios with 95% confidence intervals (95% CI) were calculated using random effects models. Results: Sixteen studies were included for analysis. 300 patients were included with an average age of 68, and a male predominance of 57%. The quality of the papers included were at risk of bias. The pooled rate of technical success of procedure was 94.4% (95% CI 90.5–96.8%) The pooled rate of clinical success was 77.6% (95% CI: 66.6–85.7%). Adverse effects were low, with perforation 8.8% (4.5–16.6%), recurrence 26.5% (17.2–38.5%) and stent migration 22.5% (14.1–33.8%). Discussion: This systematic review demonstrated that SEMS for benign colonic obstruction can be a safe and successful procedure. The utilisation of SEMS in malignant disease as a bridge to surgery has been well documented. Whilst the limitations of the data interpreted are appreciated, we postulate that SEMS could be utilised to decompress patients acutely and allow pre-operative optimisation, leading to a more elective surgery with less subsequent morbidity.

Introduction: The effect of using intravascular ultrasound (IVUS) during percutaneous coronary intervention (PCI) on short-term mortality is not well established. Aim: To evaluate any association between the use of IVUS vs. no IVUS during PCI and mortality in a large inpatient database. Material and methods: We used the National Inpatient Sample (NIS) database for available ICD-10 codes from 2016-2020 for IVUS and PCIs. Results: A total of 10,059,56 PCIs were performed. In 206,910, IVUS-guided PCI was performed vs. 9,852,359 without IVUS. Mortality did not differ between the two groups, with 2.52% mortality in the IVUS arm vs. 2.59% in no IVUS cohort, p = 0.4. The mean age of patients with IVUS use was 65.5 vs. 70.1 years without IVUS, p < 0.001. Total in-hospital cost in the IVUS group was double that without IVUS ($141,920 vs. $71,568, p < 0.001). Furthermore, IVUS utilization was significantly higher in patients with private health insurance (28.3% vs. 17.2%, p < 0.001). Conclusions: In-patient all-cause mortality using IVUS during PCI was similar to that in patients without IVUS utilization, but the cost was doubled, with higher utilization in privately insured patients.

Background: Management of a heavily calcified atherosclerotic occlusive disease involving the common femoral artery (CFA) and external iliac artery (EIA), poses a surgical challenge. Though the current guidelines recommend open surgical therapy for such lesions, this approach is neither easy nor represents the current real-life practice. Purpose: To describe tips and tricks facilitating the hybrid technique for the management of distal iliofemoral atherosclerotic disease, where classic endarterectomy is inadequate or ill-performed. Technique: A contralateraly inserted guidewire reaches the distal iliac artery via the crossover technique and is directly retrieved from the femoral arteriotomy immediately after removal of the anterior plaque segment. The retrieved and secured guidewire enables extensive retrograde CFA endarterectomy over the wire with avusion proximally to the inguinal ligement, followed by patch arterioplasty. Externalizing the guidewire from the patch enables traction on it and facilitates advancement of the stent through tortuous or stenosed iliac vessels as well as accurate stent deployment to cover the margin of the EIA residual plaque. Moreover, this manipulation enables ipsilateral placement of a sheath and passage of a second, retrograde guidewire to perform kissing stenting in the common iliac vessels. Chronic thrombotic lesions require covered stents to avoid thrombus propagation and meticulous flushing before completion of the femoral patching. Conclusions: The combined iliofemoral endarterectomy with stenting does not require advanced endovascular skills and prevents complications associated with incomplete femoral endarterectomy. Extensive avulsion endarterectomy proximal to the inguinal ligament is efficiently and safely performed over a retrieved crossover guidewire, enabling precise residual stenting above the flexion site.

Background: Progression of non-target lesions (NTLs) after stenting has been reported and is associated with the triggering of an inflammatory response. The perivascular fat attenuation index (FAI) may be used as a novel imaging biomarker for the direct quantification of coronary inflammation. Objectives: To investigate whether FAI values can help identify changes in inflammation status in patients undergoing stent implantation, especially in NTLs. Methods: Patients who underwent pre- and post-stenting coronary computed tomography angiography (CCTA) examination between January 2015 and February 2021 were consecutively enrolled. The pre- and post-stenting FAIs of the full coronary arteries were compared in both the non- and stent-implanted coronary arteries. Moreover, local FAI values were measured and compared between the NTLs and target lesions in the stent implantations. We also compared changes in plaque type and volume in NTLs before and after stenting. Results: A total of 89 patients (mean age 61 years; male 59) were enrolled. The perivascular FAI values in the full coronary arteries decreased after stenting in both the non- and stent-implanted coronary arteries, similar to those in the target lesions. Conversely, the perivascular FAI values in the NTLs increased after stenting (p < 0.05). In addition, the plaque volumes significantly increased in the NTLs after stenting, regardless of whether they were non-calcified, mixed, or calcified (p < 0.05). Conclusion: Perivascular FAI values and plaque volumes increased in the NTLs after stenting. Perivascular FAI can be a promising imaging biomarker for monitoring coronary inflammation after stenting and facilitate long-term monitoring in clinical settings. Clinical relevance statement: Perivascular fat attenuation index, a non-invasive imaging biomarker, may help identify coronary arteries with high inflammation in non-target lesions and facilitate long-term monitoring, potentially providing an opportunity for more targeted treatment. Key Points: • Perivascular fat attenuation index (FAI) values and plaque volumes increased in the non-target lesions (NTLs) after stenting, suggesting potential focal inflammation progression after stenting. However, stenting along with anti-inflammatory treatment ameliorated inflammation in the full coronary arteries. • Perivascular FAI, a non-invasive imaging biomarker, may help identify coronary arteries with high inflammation in NTLs and facilitate long-term monitoring, potentially providing an opportunity for more targeted treatment.

Purpose: LVAD outflow graft stenosis continues to remain prevalent with a high complication rate. We sought to pool the existing evidence on indications, utilization patterns, and outcomes of transcatheter interventions for outflow graft stenosis in the HeartMate 3 LVAD. Methods: An electronic search was performed to identify all studies in the English literature reporting on HeartMate 3 LVAD outflow graft stenting. Patient‐level data were extracted for analysis. Results: Thirteen published reports and one unpublished case comprising a total of 28 patients were included. Median patient age was 68.5 years [Interquartile range: 58, 71] and 25.9% (7/27) were female. Dyspnea [60.7% (17/28)] was the most common presenting symptom. Low flow alarms were present in 60% (15/25) of patients. Findings included external compression [35.7% (10/28)], graft twist [21.4% (6/28)], graft twist and external compression [14.3% (4.28)], intraluminal thrombus [10.7% (3/28)], graft twist and intraluminal thrombus [3.6% (1/28)], and pseudoaneurysm of outflow graft [3.6% (1/28)]. Median time from LVAD implantation to stenting was 2.1 years [1.4, 3]. Immediate flow normalization after stenting was observed in 85.7% (24/28). The 30‐day mortality was 12% (3/25). Overall mortality was 12% (3/25) at a median follow‐up of 3.9 months [1, 17]. Conclusion: Outflow graft stenting in the HeartMate 3 LVAD appears to be a reasonable treatment option for outflow graft stenosis, with low overall rates of complications and mortality. Further refinement of indications and approaches may improve outcomes. [ABSTRACT FROM AUTHOR]

Background: External iliac artery endofibrosis (EIAE) is a rare vascular disease which has been traditionally seen in avid cyclists. The conventional approach has been surgery, although no high-quality evidence suggests superiority of surgery over percutaneous endovascular intervention. There are limited data on the efficacy of stenting in EIAE. Methods: Over a 14-year period, we treated 10 patients (13 limbs) with EIAE with stents. These patients had declined surgery. The mean follow up was 8.4 ± 3.3 years. There were eight women. Five patients were competitive runners, three were cyclists, and two were triathletes. The mean age was 40.7 ± 2.9 years and body mass index was 19.46 ± 1.6. Intravascular ultrasound (IVUS) was used in eight limbs. Results: Procedural success was achieved in all. The recurrence of symptoms occurred in three patients at a mean of 9.3 ± 2.1 months postindex intervention. The other seven patients remained symptom free. IVUS revealed a pathognomonic finding which we termed 'perfect circle appearance'. It results from symmetric or asymmetric hypertrophy of one or more layers of the arterial wall leading to negative remodeling, which creates a distinct echo dense structure contrasting itself from the luminal blood's echoluscent appearance. It is identical to IVUS images of diffuse venous stenosis with important implications in the treatment technique. Conclusions: We conclude that stenting in EIAE is safe and effective with a good long-term outcome. It can be an alternative to surgery, particularly in those patients who refuse a surgical approach. The IVUS image is pathognomonic and 'sine qua non' of EIAE. [ABSTRACT FROM AUTHOR]

• Postoperative new sNCLI assessed by DWI was detected in 28.2% of patients after CAS. • A higher PCT level is identified as an independent risk factor for the development of sNCLI in patients treated with endovascular intervention for carotid artery stenosis. • Other independent risk factors for the development of sNCLI include advanced age and the absence of embolism protection device use. Silent new cerebral ischemic lesions (sNCIL) are a common complication of carotid artery stenting (CAS) that can lead to an increase in morbidity and mortality. We aimed to evaluate the impact of hematological parameters on sNCIL in patients undergoing CAS. We retrospectively evaluated 103 patients who underwent CAS, with a mean age of 70.5 ± 6.7 years, and 31 (20.1 %) of whom were female. Stents were placed for internal carotid artery revascularization. The presence of new hyperintense lesions on diffusion-weighted imaging (DWI) without neurological symptoms was considered as sNCIL in cases without apparent neurological findings. Patients were categorized into two groups based on DWI results: positive (29) and negative (74). In the study population, sNCIL was observed in 29 patients (28.2 %). The DWI-positive group exhibited significantly higher Plateletcrit (PCT) levels, advanced age, and a lack of embolic protection device usage compared to the DWI-negative group. The Receiver Operating Characteristic (ROC) analysis identified a PCT value of 0.26 as the optimal threshold, detecting the development of sNCIL with a sensitivity of 75.9 % and specificity of 59.1 % (AUC: 0.700; 95 % CI: 0.594–0.806, p = 0.002). To be determined by a simple blood parameter, PCT can predict the risk of sNCIL before CAS and holds clinical value in the treatment of patients with carotid artery stenosis. [ABSTRACT FROM AUTHOR]

Background: Carotid artery stenting has been used effectively to treat internal carotid artery stenosis since 1989 (Mathias et al. in World J Surg. 25(3):328-34, 2001), with refined and expanded techniques and tools presently delivering outstanding results in percutaneous endoluminal treatment of carotid artery stenosis. Purpose: This CIRSE Standards of Practice document is directed at interventional radiologists and details the guidelines for carotid artery stenting, as well as the different implementation techniques. In addition to updating all previously published material on the different clinical indications, it will provide all technical details reflective of European practice for carotid artery stenting. CIRSE Standards of Practice documents do not aim to implement a standard of clinical patient care, but rather to provide a realistic strategy and best practices for the execution of this procedure. Methods: The writing group, which was established by the CIRSE Standards of Practice Committee, consisted of five clinicians with internationally recognised expertise in carotid artery stenting procedures. The writing group reviewed existing literature on carotid artery stenting procedures, performing a pragmatic evidence search using PubMed to select relevant publications in the English language from 2006 to 2022. Results: Carotid artery stenting has an established role in the management of internal carotid artery stenosis; this Standards of Practice document provides up-to-date recommendations for its safe performance.

ObjectivesBalloon dilation followed by balloon-expandable stent implantation is an effective treatment for improving hemodynamic status in patients with coarctation of the aorta (CoA). However, limited evidence exists regarding the safety and efficacy of covered balloon-expandable stents (CBSs) in a large cohort. In this meta-analysis, we aimed to evaluate the overall success rates, hemodynamic and anatomical benefits, complications, and mid-term results of CBSs in treating CoA.MethodsThe PubMed, Embase, and Cochrane Library databases were systemically searched for studies reporting outcomes of CBSs in treating CoA. Single-group rate meta-analyses were performed to calculate estimated pooled procedural success rates, the incidence of complications, and re-coarctation rates. A meta-analysis using standardized mean differences was conducted to compare pre- and postoperative trans-coarctation pressure gradients (PGs), coarctation diameter, and overall changes in systolic blood pressure (SBP). Subgroup analyses were performed to identify potential sources of heterogeneity.ResultsThe final analysis included 12 studies with a total of 411 patients. The estimated pooled procedural success rate was 100% [95% confidence interval (CI): 98%–100%, I2 = 0, P = 0.78]. Significant decreases in trans-coarctation PGs and SBP were observed. The pooled incidences of stent-related, aortic, and access site complications were 2% (95% CI: 0%–5%, I2 = 30.4%, P = 0.15), 2% (95% CI: 0%–4%, I2 = 0%, P = 0.76), and 3% (95% CI: 1%–7%, I2 = 52.9%, P = 0.02), respectively. Subgroup analyses showed that implantation of BeGraft stents was related to a significantly higher incidence of access site complications.ConclusionCovered balloon-expandable stent implantation in treating CoA is safe and effective with high procedural success rates, an acceptable incidence of complications, and a low incidence of re-coarctation.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/, PROSPERO (CRD42023430356).

Objective To explore the effect of age factor on the success rate of lacrimal probing in the congenital nasolacrimal duct obstruction (CNLDO). Methods This report was based on a single-center retrospective case series study. The gradient therapeutic regimen was adopted, and lacrimal probing was undertaken to treat CNLDO when conservative treatment was ineffective. The patients were categorized into 4 groups by age: 0-＜6 months,6-＜12 months,12-＜24 months and 24-60 months. The success rate of probing in each group was compared and the correlation with age was analyzed. Results A total of 314 eyes of 269 patients were included. The success rates of primary probing in 4 groups were 86.8%, 91.7%, 73.6% and 37.8%, respectively. The overall success rate of probing in all patients was 84.7%(266/314). The decreased success rate of probing at age beyond 12 months was significantly correlated with increasing age(P＜0.001). No significant correlation was found with sex or laterality. Conclusions Staged treatment strategy is safe and effective. The success rate of probing is negatively correlated with age. Initial probing is recommended in children under 2 with failure of the conservative management.

Tracheal stenosis due to invasion of thyroid malignancy is a rare entity. Management of the airway in such a patient is a critical step in palliative care. We discuss the successful management of tracheal stenosis due to anaplastic transformation of papillary thyroid carcinoma in an 84-year-old female. There are several methods for airway management in tracheal stenosis. Self-expanding stent placement is a less invasive, efficient procedure for tracheal stenosis.

Tibial artery pseudoaneurysms often result from penetrating or blunt trauma to the lower extremities, or after orthopedic and endovascular interventions. Clinically, these lesions manifest as an expanding pulsatile mass of the affected area accompanied with pain and erythema. Despite the rare occurrence, traumatic tibial pseudoaneurysms can be associated with significant morbidity including local discomfort, rupture, and lower limb ischemia. Duplex ultrasound is considered the gold standard for diagnosis. Treatment options include surgical repair, ultrasound-guided compression or thrombin injection, and endovascular repair. In this report, we describe a 42-year-old male who presented to our center with pulsatile swelling over the mid-lateral aspect of the left leg. The diagnosis of a large anterior tibial artery pseudoaneurysm was made on clinical basis and was confirmed with computed tomography angiography. The lesion was treated endovascularly with a covered stent graft. In conclusion, this case highlights the role of endovascular therapy as a surgery-sparing and minimally invasive approach in managing traumatic peripheral arterial pseudoaneurysms with excellent clinical outcomes.

Background: Endovascular treatment of severe intracranial atherosclerotic stenosis (ICAS) using coronary drug-eluting stents (DESs) significantly reduces the risk of in-stent restenosis (ISR) and stroke recurrence. However, there are few reports regarding the treatment of ICAS with intracranial dedicated DES. Herein, we present our experience with the feasibility, safety, and medium-term follow-up outcomes of a novel intracranial DES, named NOVA stent, in patients with symptomatic severe ICAS (≥70%). Methods: From December 2021 to May 2022, patients with symptomatic severe ICAS who underwent implantation of the NOVA stent in our institution were retrospectively analyzed for procedural results, perioperative complications, imaging and clinical follow-up outcomes. Results: Twenty-four patients, 16 (66.7%) with anterior circulation lesions and 8 (33.3%) with posterior circulation lesions, were enrolled. All patients with intracranial ICA (n = 6), middle cerebral artery (n = 10), basilar artery (n = 3), intracranial vertebral artery (n = 3), and the vertebrobasilar junction (n = 2) stenosis were treated successfully using NOVA stents. The severity of stenosis ranged from 75 to 96% (mean 85.9%) before treatment and this was reduced to 0 to 20% (mean 8.6%) immediately after stent placement. Symptomatic distal embolism occurred in one case; however, there were no other perioperative complications. The mean follow-up duration was 12.2 ± 1.06 months. No symptomatic ischemic events occurred during follow-up. Follow-up cerebral angiography was performed in 22 of 24 patients (91.7%), and significant ISR occurred in one patient (4.2%). Conclusion: Our results demonstrate that implantation of the novel intracranial DES NOVA in severe ICAS is feasible, safe, and effective in selected cases, reducing the incidence of ISR, and showing excellent midterm clinical outcomes, providing a promising option for ICAS treatment.

Objectives: Perioperative stroke is the most dreaded complication of carotid artery interventions and can severely affect patients' quality of life. This study evaluated the impact of this event on mortality for patients undergoing interventional treatment of carotid artery stenosis with three different modalities. Methods: Patients undergoing carotid revascularization at participating Memorial Hermann Health System facilities were captured from 2003-2022. These patients were treated with either carotid endarterectomy (CEA), transfemoral carotid stenting (TF-CAS), or transcarotid artery revascularization (TCAR). Perioperative outcomes, including stroke and mortality, as well as follow-up survival data at 6-month intervals, were analyzed and stratified per treatment modality. Results: Of the 1681 carotid revascularization patients identified, 992 underwent CEA (59.0%), 524 underwent TCAR (31.2%), and 165 underwent TF-CAS (9.8%). The incidence of stroke was 2.1% (CEA 2.1%, TCAR 1.7%, and TF-CAS 3.6%; P =.326). The perioperative (30-day) death rate was 2.1% (n = 36). The perioperative death rate was higher in patients who suffered from an intraoperative stroke than in those who did not (8.3% vs 1.9%, P =.007). Perioperative death was also different between CEA, TCAR, and TF-CAS for patients who had an intraoperative stroke (.0% vs 33.3% vs.0%, P =.05). TCAR patients were likely to be older (P <.001), have a higher body mass index (P <.001), and have diabetes mellitus (P <.001). Patients who suffered from an intraoperative stroke were more likely to have a symptomatic carotid lesion (58.3% vs 28.8%, P <.001). The TCAR group had a significantly lower survival at 6 months and 12 months when compared to the other two groups (64.9% vs 100% P =.007). Conclusion: Perioperative stroke during carotid interventions significantly impacts early patient survival with otherwise no apparent change in mid-term outcomes at 5 years. This difference appears to be even more significant in patients undergoing TCAR, possibly due to their baseline higher-risk profile and lower functional reserve. [ABSTRACT FROM AUTHOR]

Background: This study examines the impact of the use of the combination of BeGraft and Solaris stent grafts on the outcomes during the covered endovascular reconstruction of aortic bifurcation (BS-CERAB) technique and extension to the iliac arteries. Methods: Consecutive patients with aortoiliac occlusive disease who underwent endovascular treatment using BS-CERAB between January 2020 and December 2023 were included. Patient demographics, symptoms, lesion characteristics, and procedural and follow-up details were collected and analyzed. Perioperative complications and reinterventions were also identified. Results: A total of 42 patients met the inclusion criteria (32 men, 76.2%, median age 72 years, range 59–85). Indications for treatment were intermittent claudication (42.9%) and critical limb ischemia (57.1%). Procedure success was achieved in all cases. The median patient follow-up time was 14 months (1–36). One patient died at a 10-month follow-up due to lung cancer. The mean pre-operative ABI increased from 0.37 ± 0.19 before intervention to 0.71 ± 1.23 post-operatively at 12 months (p = 0.037). The estimated primary patency rates at 3, 6, and 12 months were 90.5%, 85.7%, and 81.0% and primary assisted patency rates were 90.5%, 90.5%, and 85.7%, respectively. Secondary patency was 95.2% at 3 and 6 months and 90.5% at a 12-month follow-up. Active cancer (p = 0.023, OR 2.12 95%CI 1.14–3.25) was a risk factor for restenosis. Conclusions: This mid-term experience shows that the CERAB technique using the combination of BeGraft and Solaris stents grafts, for the endovascular treatment of severe aortoiliac atherosclerotic disease, may allow an effective reconstruction of the aortic bifurcation and iliac arteries related to high-patency and lower-reintervention rates.

Although numerous case series and meta-analyses have shown the efficacy of venous sinus stenting (VSS) in the treatment of idiopathic intracranial hypertension and idiopathic intracranial hypertension–associated pulsatile tinnitus, there remain numerous challenges to be resolved. There is no widespread agreement on candidacy; pressure gradient and failed medical treatment are common indications, but not all clinicians require medical refractoriness as a criterion. Venous manometry, venography, and cerebral angiography are essential tools for patient assessment, but again disagreements exist regarding the best, or most appropriate, diagnostic imaging choice. Challenges with the VSS technique also exist, such as stent choice and deployment. There are considerations regarding postprocedural balloon angioplasty and pharmacologic treatment, but there is insufficient evidence to formalize postoperative decision making. Although complications of VSS are relatively rare, they include in-stent stenosis, hemorrhage, and subdural hematoma, and the learning curve for VSS presents specific challenges in navigating venous anatomy, emphasizing the need for wider availability of high-quality training. Recurrence of symptoms, particularly stent-adjacent stenosis, poses challenges, and although restenting and cerebrospinal fluid–diverting procedures are options, there is a need for clearer criteria for retreatment strategies. Despite these challenges, when comparing VSS with traditional cerebrospinal fluid–diverting procedures, VSS emerges as a favorable option, with strong clinical outcomes, lower complication rates, and cost-effectiveness. Further research is necessary to refine techniques and indications and address specific aspects of VSS to overcome these challenges. [ABSTRACT FROM AUTHOR]
