49. Gender Differences In Aortic Neck Morphology In Patients With Abdominal Aortic Aneurysms Undergoing EVAR

Abstract

Introduction and Objectives: Prior studies have alluded to gender differences in aortic neckmorphology resulting in anatomic exclusion of some women from EVAR. The objective of this study is to correlate gender differences in aortic neck morphology and changes in the neck and aneurysm sac after EVAR. Methods: A retrospective review of consecutive EVARs performed for infrarenal AAA was conducted from 2004 to 2013 at a single institution. Preand post-operative imaging studies were utilized to measure aortic neck length and diameter, shape, and angulation, aneurysm sac diameter. Volumetric analysis of neck thrombus burden was performed using TeraRecon . Results: 146 patients met inclusion criteria 21% were women with a mean age of 75.5 (p1⁄40.724) with comparable baseline comorbidities to men. Neck angulation was greater in women 23.9 vs 13.5 (P<0.028). The percent thrombus of the aortic neck was greater in female patients at 35.7% vs 30%(P1⁄40.02). Preoperative AAA diameter
