Collapse of VBX Balloon-Expandable Endoprosthesis in Bilateral Common Iliac Arteries in a Lean, Elderly Patient with Bent Back

Background: 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. Material and methods: 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. Results: 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 25mm 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. Conclusions: 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.

Common Iliac Arteries

Abstract Background and aims: The abdominal aorta usually terminates at the level of L4 vertebral body into common iliac arteries. With the present day advancements in vascular surgery and neurological surgeries involving approach to lumbar vertebral bodies, we need to know any variations from this normal course. So, the present study aimed at knowing the anatomical variations in the termination of abdominal aorta and in common iliac arteries which might prove to be of some help in some of such surgeries. Material and methods: The study was conducted on 35 adult (29 males and 6 females) embalmed cadavers obtained from anatomy departments of Govt. Medical college, Amritsar and Gian Sagar Medical college, Ramnagar, Punjab. The abdominal cavity was opened, peritoneum stripped off from aorta at its bifurcation, variations in its termination, common iliac arteries and their branches were carefully observed and recorded. Results: In 54.29% cases the level of aortic bifurcation was found opposite 4th Lumbar vertebra, in the rest it was variable between L3 and L5 vertebra. Conclusions: These variations may lead to some trouble during vertebral surgeries, making it essential to investigate and locate the exact position of great vessels before the commencement of surgery.
