Abstract

The long-term survival of patients treated from descending thoracic aneurysm (DTA) is well known, more than those treated from a thoracoabdominal aortic aneurysm (TAAA). Moreover, studies are rarely focused on the aneurysmal etiology and include both degenerative and post dissecting aneurysms. The aim of this study is to compare the long-term survival of patients operated from DTA or TAAA due to degenerative atherosclerosis. Thirty-nine atherosclerotic aneurysm patients were operated between January 2007 and July 2015 at Rouen University Hospital. Eighteen DTA patients were operated by TEVAR and 21 TAAA patients (8 type I and 13 type III) by open approach. The main endpoint was remote survival patients. Overall, the initial population was similar in the two groups. However, one third of DTA were treated in context of emergency for painful aneurysm versus 9.5% of patients with TAAA (P=0.066). Survival median of 18 DTA was 18 months (1-68). Survival median of 21 TAAA followed was 66 months (1-91). Survival in both groups was statistically different with the log-rank test (P=0.044). Long-term prognosis of atherosclerotic DTA may be worse than that of TAAA's. This retrospective study reflects experience in the management of DTA and...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.

Aneurysm

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