Abstract

The purpose of this study was to compare the anatomy of the aortoiliac vessels in patients scheduled for infrarenal abdominal aortic aneurysm (AAA) repair in four different countries. Consecutives series of 100 preoperative CT-scans were evaluated at each center. Diameters of the suprarenal aorta, maximal diameter of the aneurysm, right and left common and external iliac artery as well as the hypogastric arteries were recorded and compared between each center. Configuration of the AAA above bifurcation was similar at each center. The dimensions of the aortic bifurcation and the common iliac arteries were different among the centers. Common iliac arteries with diameters over 25 mm were significantly more common at center 1 (p < 0.001, p = 0.002 and p < 0.001). Among centers 2, 3 and 4 there was no significant difference in common iliac diameters. Configuration of the iliac arteries in AAA was significantly different for Swiss patients compared to American, Austrian and German patients. Reasons for these differences are unclear, epidemiological or genetic factors may be responsible.

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.
