What factors counteract mid-term survival following endovascular repair of abdominal aortic aneurysms?

Abstract

Introduction: Endovascular aortic aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) is increasingly used, and has become the standard treatment option for AAA. Aim: To evaluate the outcomes and predictors of survival of endovascular treatment of AAA in the short-and medium-term. Material and methods: A total of 222 patients having endovascular AAA repair between January 2013 and December 2019 by the same surgical team were included in the study. Patient demographics, perioperative and follow-up data including mortality, complications, and need for secondary intervention were collected. The primary endpoint was all-cause mortality. Kaplan-Meier analysis was conducted for survival and Cox regression models were assessed for predictors of survival. Results: The median age was 70 years, with male predominance (202 patients, 91%). Thirty-day mortality was 1.8%. Median follow-up to the primary endpoint was 20 months (range: 1-80 months).

Combined Endovascular Treatment of Complex Aortic Pathologies

“…Among the patients who were simultaneously treated and not, the simultaneously treated group was older in age (76 vs. 70 years on average), LOS was longer (6 vs. 2 days on average), and the amount of contrast material was higher (80 vs. 60cc in average); however, fluoroscopy period and ICU period were nearly the same. 23 As the study groups were from different time intervals, there was no statistical analysis.…”
