Nonresective therapy for aortic aneurysm: results of a survey

Abstract

We reviewed the experience of 120 vascular surgeons with nonresective therapy for abdominal aortic aneurysm (AAA) in medically unstable patients. Of a total pool of 206 patients, 88 underwent iliac artery ligation, which was combined with angiographic attempts at intrasaccular thrombosis in 80% of cases. The remaining 118 patients had ligation of the aneurysm proximally and distally. In all cases distal perfusion was restored, usually by axillofemoral bypass. Our study demonstrated a significantly higher risk of postoperative AAA rupture (20% vs. 3.3%, p less than 0.0001) and death (34% vs. 5.1%, p less than 0.000001) among patients treated by ligation distal to the AAA alone, whether intrasaccular thrombosis occurred or not. These results support the contention that if nonresective therapy is chosen for the occasional patient deemed too ill to undergo standard AAA resection, AAA exclusion by proximal and distal ligation should be performed.

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.
