https://www.selleckchem.com/products/a-438079-hcl.html OBJECTIVE There is a growing body of literature raising concerns about the long-term durability of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs), suggesting that long-term outcomes may be better after open AAA repair. However, the data investigating these long-term outcomes largely originate from early in the endovascular era and therefore do not account for increasing clinical experience and technologic improvements. We investigated whether 4-year outcomes after EVAR and open repair have improved over time. METHODS We identified all EVARs and open repairs for intact infrarenal AAA within the Vascular Quality Initiative database (2003-2018). We then stratified patients by procedure year into treatment cohorts of four years 2003-2006, 2007-2010, 2011-2014, and 2015-2018. We used Kaplan-Meier analysis and Cox proportional hazards models to assess whether the survival after EVAR or open repair changed over time. In addition, we propensity matched EVAR and open repairs for each time co, in matched EVAR and open repairs, there was no difference in mortality in the first three cohorts, whereas the hazard of mortality was lower for the 2015-2018 cohort (HR, 0.65; 95% CI, 0.51-0.84; P = .001). CONCLUSIONS Four-year survival improved in more recent years after EVAR but not after open repair. This finding suggests that midterm outcomes after EVAR are improving, perhaps because of technologic improvements and increased experience, information that should be considered by surgeons and policymakers alike in evaluating the value of contemporary EVAR and open AAA repair. OBJECTIVE The goal of this study was to analyze our 10-year experience in the treatment of aneurysms of the collateral circulation secondary to steno-occlusions of the celiac trunk (CT) or superior mesenteric artery (SMA). METHODS In the last 10 years, 32 celiac-mesenteric aneurysms were detected (25 true aneurysms and seven pseudoa
