Flow in a mold of an atherosclerotic human abdominal aorta and common iliac arteries was studied by flow visualization at a mean Reynolds number of 500 during both pulsatile and steady flow. Flow separation and transient flow reversals were found distal to atherosclerotic plaques during pulsatile flow; whereas flow separation resulting in regions of permanent eddies were observed distal to plaques only during steady flow.

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.

Hip Flexion

Abdominal aortic aneurysm stent grafts have been reported to fracture at a rate as high as 8% [1]. Iliac artery deformation induced by cardiac pulsation or musculoskeletal motions has been hypothesized to cause these fractures, but little in vivo data has been available heretofore to test this hypothesis. We have utilized magnetic resonance angiography and image-processing methods to quantify in vivo deformation of the human iliac arteries due to maximal hip flexion.

The case of a 58-year-old woman with leg claudication due to a very rare form of atherosclerosis affecting the descending thoracic and abdominal aorta – known as coral reef aorta – without involvement of the femoro-distal vessels is reported. The patient was treated with a polyester bifurcation graft from the proximal descending aorta to both common iliac arteries via a left dorsal minithoracotomy and a second left retroperitoneal approach. This unusual approach was chosen instead of direct aortic replacement in order to prevent paraplegia. In case of future visceral or left renal malperfusion the diseased artery can be connected to the prosthesis directly or by the use of an additional bypass graft. This would not be the case with a conventional axillo-bifemoral graft.
