Multicenter Study Clinical Trial
Aortic remodeling after endovascular repair of acute complicated type B aortic dissection.
The role of thoracic endovascular aortic repair (TEVAR) in the management of acute type B aortic dissection remains undefined. Entry tear coverage during the acute phase is an appealing method to treat acute complications, and by inducing false lumen thrombosis, might also prevent late aneurysm formation. This study evaluated structural changes by serial computed tomography (CT) in the thoracic aorta after TEVAR performed for acute complicated aortic dissection. ⋯ TEVAR of acute complicated aortic dissection appears to promote early aortic remodeling. Nearly 90% of patients maintained at least partial false lumen thrombosis at 1 year. Because continued false lumen patency correlates strongly with late aneurysm formation, such favorable remodeling is considered a surrogate for prevention of late aneurysm, but longer follow-up is required.

Multicenter Study
Gender and 30-day outcome in patients undergoing endovascular aneurysm repair (EVAR): an analysis using the ACS NSQIP dataset.
Prior studies have demonstrated higher in-hospital mortality in women undergoing open abdominal aortic aneurysm repair. The current study evaluates the relationship between gender and 30-day outcomes for endovascular aneurysm repair (EVAR) in a multicenter, contemporary patient population. ⋯ Mortality and morbidity were higher in women than men undergoing EVAR. Multivariate analysis showed that the increased risk of mortality was related to women presenting more emergently, more debilitated (recent weight loss and functional dependence), and requiring iliac or brachial exposure. After adjustment for multiple preoperative and operative factors, women remained at significantly higher risk for the development of a broad range of complications and increased length of stay.
