In medicine, aortoiliac occlusive disease is a form of central artery disease involving the blockage of the abdominal aorta as it transitions into the common iliac arteries. Signs and symptoms [ edit ]
Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet. [6]
Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]
In addition, ischemic colitis is a well-recognized complication of abdominal aortic aneurysm repair, when the origin of the inferior mesenteric artery is covered by the aortic graft. [ 13 ] [ 14 ] In a 1991 review concerning 2137 patients the accidental inferior mesenteric artery ligation was the most common cause (74%) of ischemic colitis. [ 15 ]
The common iliac artery is a large artery of the abdomen paired on each side. It originates from the aortic bifurcation at the level of the 4th lumbar vertebra . It ends in front of the sacroiliac joint , one on either side, and each bifurcates into the external and internal iliac arteries .
It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery." These vessels supply blood to the muscles and skin in the lower abdominal wall. The external iliac artery passes beneath the inguinal ligament in the lower part of the abdomen and becomes the femoral ...
Risk factors, present in around 50% of documented cases, include malignancy, hyper-coagulable states, cardiac disease, venous stasis, venous insufficiency, May-Thurner syndrome (right iliac artery compressing the left iliac vein that runs beneath it), surgery, trauma, pregnancy, inferior vena cava (IVC) filter, hormone therapy, oral contraceptives, prolonged immobilization, inflammatory bowel ...
Used when there is no inflow to one femoral artery (i.e., the iliac artery on the receiving side is diseased) but there is aortic flow. "aorto-bifem" - aortic to both femoral arteries. Used when there is disease at the aortic bifurcation, known as Leriche syndrome, or in both iliac arteries. "ax-bifem" - axillary artery to both femoral artery ...
