Abstract

To analyze the outcome of abdominal aortic aneurysm (AAA) repair with elective open surgery (OS) versus endovascular aneurysm repair (EVAR) and assess the predictors of survival. A retrospective cohort study was made of 1000 AAA treated between January 1998 and November 2014 (68.1% OS and 31.9% EVAR), with the comparison of comorbidity and complications, and survival analysis (Kaplan-Meier and Breslow). Multivariate logistic regression and Cox regression analyses were performed. The EVAR group had a higher prevalence of smokers (33.2% vs. 21%; P < 0.001), hypercholesterolemia (56.4% vs. 41.1%; P < 0.001), type 1 diabetes (11.3% vs. 2.8%; P < 0.001), ischemic heart disease (36.4% vs. 25.0%; P = 0.013), chronic renal failure (25.4% vs. 16.2%; P < 0.001), and an older age [74.6 ± 7.1 vs. 68.3 ± 7.2 (years); P < 0.001]. The OS group showed a greater prevalence of chronic ischemia of the lower extremities (22.8% vs. 9.4%; P < 0.001), a greater AAA diameter [61.2 ± 13.6 vs. 58.5 ± 13.8 (mm); P < 0.001], a greater aneurysm neck diameter [24.1 ± 3.9 vs. 23.3 ± 3.0 (mm); P = 0.002], and a shorter aneurysm neck length [15.1 ± 11.1 vs. 24.0 ± 11.1 (mm); P < 0.001]. Early mortality was low in both groups but higher with OS (1.9% vs. 0.3%; ...Continue Reading

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
