Abdominal Aortic Occlusion (Leriche Syndrome)

* Occlusion of the abdominal aorta can occur from a variety of causes including trauma, thromboembolism, or iatrogenic dissection. Atherosclerosis is the most common cause
* Symptoms of ischemia may not appear until occlusion is imminent and some patients may present after the occlusion has occurred
* The classic symptoms of Leriche’s syndrome are seen in men and include hip and buttock claudication, absent femoral pulses, importance, and cool lower extremities
* If development of occlusion is slow than large intercostal, lumbar, and epigastric collaterals that provide flow to the iliac arteries and lower-extremity vessels may develop
* Treatment of choice is surgical bypass graft placement
