Aneurysm sac shrinkage after endovascular repair: predictive factors and long-term follow-up

Annals of Vascular Surgery
Raphael J SolerPierre-Edouard Magnan

Abstract

The aim of this study was to determine the predictive factors of reduction in diameter ≥10 mm of the aneurysm sac after endovascular treatment and analyze evolution in these patients. Between December 1997 and December 2008, all patients electively treated at our center for an infrarenal abdominal aortic aneurysm (AAA) were included in a prospective registry. We did a retrospective study between patients whose aneurysm was reduced by at least 10 mm in diameter on computed tomography scan during follow-up (Group 1) and the other patients who did not (Group 2). A univariate and multivariate statistical analysis was performed. The files of 197 patients (mean age 74.8 years) with a mean follow-up of 54.8 months were reviewed. One hundred two patients (51.8%) had a reduction of ≥10 mm of AAA diameter (Group 1); this reduction was achieved after an average follow-up of 23.6 months. The delay to obtain at least a 10-mm diameter reduction was not influenced by any preoperative characteristics of patients or characteristics of the AAA. Patients in Group 1 were younger (74 vs. 76 years, P = 0.039), with a longer (31 vs. 27.7 mm, P = 0.038) and narrower upper neck (23.1 vs. 24.0 mm, P = 0.02) compared with Group 2. After multivariate anal...Continue Reading

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.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Aneurysm

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

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.
