[Dissection and dissected aneurysm of the abdominal aorta].

Experience in successful treatment of 7 patients with isolated dissection of the abdominal aorta is presented. Over the last 10 years 165 patients with dissected aneurysms of different sites underwent surgery. In 7 (4.2%) of them isolated dissection of the abdominal aorta was diagnosed. Among 251 patients operated for abdominal aortic aneurysm dissection of its wall was seen in 2.8% cases. Morphologic study revealed atherosclerosis in 3 patients, degeneration of aortic wall - in 3, and combination of dysplasia with atherosclerosis - in 1. Linear prosthesis of abdominal aorta with replantation of visceral branches on single area into graft was the main (6) surgery. Bifurcation aorto-iliac prosthesis with bypass of the distal part of the deep femoral artery was performed in 1 patient. Five patients underwent elective surgery, 2 - emergency surgery.
