Leriche Syndrome


         Atheromatous occlusion of the distal abdominal aorta at the bifurcation into the common iliac arteries

         Triad of symptoms includes

o       Claudication in the legs or buttocks

o       Absent or diminished femoral pulses

o       Erectile dysfunction

         Usually affects younger males ages 30-40

         Risk factors include

o       Cigarette smoking

o       Hypercholesterolemia

o       Less likely to have associated diabetes

         Because development of the disease is slow and collaterals develop, limb-threatening ischemic disease does not tend to occur

         Imaging can be done with non-invasive methods such as MRI and CT angiography or through arterial duplex scanning

         Treatment is aortoiliac bypass

Leriche Syndrome. Coronal reconstruction from a contrast-enhanced abdominal CT scan
shows complete occlusion of the infrarenal aorta (red arrow) by thrombus that extends
into both common iliac arteries (yellow arrows). The white arrow points to calcification in the wall of the vessel.
