[Abdominal aortic aneurysm binds less albumin I-125 than the atheromatous aorta].

The causes of abdominal aortic aneurysm are still poorly understood. The author studied the permeability of the aneurysm wall or the aortic wall in 21 patients with abdominal aortic aneurysm or aorto-iliac bypass by comparing 125I-albumin tissue concentrations; The results suggest that albumin crosses the aneurysm wall less easily than that of the atheromatous aorta.
