Abstract

The aim of our study was to compare early and long-term results of open repair of patients with inflammatory abdominal aortic aneurysm (IAAA) with matched cohort of patients with abdominal aortic aneurysm (AAA). This retrospective single-center cohort study used prospectively collected data from an institutional registry from 1786 patients between 2009 and 2015. Patients with IAAA and AAA were matched by propensity score analysis controlling for demographics, baseline comorbidities, and AAA parameters in a 1:2 ratio. Patients were followed for 5 years. There were 76 patients with IAAA and 152 patients with AAA. Patients with IAAA had more common intraoperative lesion of intraabdominal organs (P = .04), longer in-hospital (P = .035) and intensive care (P = .048) stays and a higher in-hospital mortality rate (P = .012). There were four patients (5.26%) with in-hospital lethal outcome in IAAA there were no deaths in the AAA group. During the follow-up, there was no difference in survival (χ2 = 0.07; DF = 1; P = .80) and overall aortic related complications (χ2 = 1.25; DF = 1; P = .26); however, aortic graft infection was more frequent in IAAA group (P = .04). Open repair of IAAA is challenging and comparing to AAA carries a higher...Continue Reading

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm 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.
