The present study investigated the incidence, causes, treatment and prevention of limb graft occlusion following endovascular aortic repair (EVAR). A total of 66 cases of abdominal aortic aneurysm receiving EVAR at our department from January 2005 to December 2013 were enrolled. After EVAR, patients received routine antiplatelet therapy of 75 mg PLAVIX for 6 months and then 100 mg Aspirin for another 6 months by oral administration. According to previous clinical experiences, antiplatelet therapy is able to effectively reduce the incidence of iliac occlusion after EVAR...

Background -In the event of rupture of an abdominal aortic aneurysm (AAA), mortality is very high. AAA prevalence and incidence of ruptures has been reported to be decreasing. The treatment of AAA has also undergone a change in recent decades with a shift towards endovascular aneurysm repair (EVAR). Our aim was to evaluate how these changes have affected the elective and emergency treatment of AAA and their results in Finland. Methods -All patients treated for AAA in Finland, a country with a population of 5...

Endovascular aneurysm repair (EVAR) has gained increasing popularity in the treatment of infrarenal abdominal aortic aneurysm. Despite its favorable early outcomes, the long-term efficacy of EVAR remains a concern. Late rupture is the ultimate treatment failure and continues to complicate EVAR. Univariate and multivariate analyses have identified factors predictive of late rupture. The importance of EVAR surveillance to prevent late complications is equally widely acknowledged. This article aims to present our current understanding of the precipitating factors of late rupture after EVAR and explores whether the key to its prevention lies within improving patient factors, particularly compliance to follow-up appointments or whether physicians hold the solution...

BACKGROUND: Endovascular aortic repair (EVAR) has emerged as a standard of care for abdominal aortic aneurysm (AAA) repair. However, real-world evidence to compare this technology to open aortic repair (OAR) is limited. Major gaps exist related to long-term outcomes of therapies worldwide. METHODS: Health insurance claims data of Germany's third largest insurance provider, DAK-Gesundheit, were used to determine outcomes after interventions for intact AAA (iAAA) and ruptured AAA (rAAA)...

BACKGROUND: Previous studies comparing endografts with suprarenal and infrarenal fixation for endovascular abdominal aortic aneurysm repair (EVAR) have found conflicting results and did not account for differences in patient selection. This study aims to evaluate the differences in outcomes among surgeons who routinely use either suprarenal or infrarenal fixation, as well as all surgeons in the Vascular Study Group of New England (VSGNE). METHODS: All patients undergoing EVAR in the VSGNE from 2003 to 2014 were identified...

BACKGROUND: Feature selection (FS) process is essential in the medical area as it reduces the effort and time needed for physicians to measure unnecessary features. Choosing useful variables is a difficult task with the presence of censoring which is the unique characteristic in survival analysis. Most survival FS methods depend on Cox's proportional hazard model; however, machine learning techniques (MLT) are preferred but not commonly used due to censoring. Techniques that have been proposed to adopt MLT to perform FS with survival data cannot be used with the high level of censoring...

Transradial access has been described in a variety of clinical contexts but has been rarely utilized for visceral artery interventions and during complex endovascular aortic aneurysm repair (EVAR) when upper extremity access is required. This is usually accomplished via brachial artery access, and although brachial access is generally safe and effective, radial access may offer some benefits with regard to patient comfort and potential complications. Here we report a case of successful delivery of a renal snorkel via a radial artery approach during EVAR...

OBJECTIVE: Compliance with regular imaging follow-up after endovascular aortic aneurysm repair (EVAR) is inconsistent, and evidence of benefit from scheduled long-term surveillance is limited. This study sought to characterize the association between post-EVAR imaging frequency and long-term survival. METHODS: Using administrative health databases for the province of Ontario, Canada, a cohort of patients was identified who underwent EVAR between 2004 and 2014. Minimum appropriate imaging follow-up (MAIFU) was defined as a CT scan or ultrasound of the abdomen within 90 days of EVAR as well as every 15 months thereafter...

BACKGROUND: A variety of devices exist for endovascular aneurysm repair (EVAR). Device-specific instructions for use (IFU) detail anatomic constraints to application and deployment of devices and are developed from rigorous bench testing. Nonadherence to IFU occurs frequently to avoid open surgery. The purpose of this study was to determine if IFU violations are associated with increased risk of graft-related adverse events (GRAEs) during follow-up. METHODS: This multicenter retrospective observational study included patients undergoing elective endovascular repair for abdominal aneurysmal disease with three different devices...

OBJECTIVE: Preoperative type and cross are often routinely ordered before elective endovascular aneurysm repair (EVAR), but the cost of this practice is high, and transfusion is rare. We therefore aimed to stratify patients by their risk of transfusion to identify a cohort in whom a type and screen would be sufficient. METHODS: We queried the targeted vascular module of the National Surgical Quality Improvement Program (NSQIP) for all elective EVARs from 2011 to 2015...
