Which statements about thrombo-obliterative disease of the terminal abdominal aorta (Leriche syndrome) are true?
- It is characterized by a combination of atherosclerotic and thrombotic occlusion of the terminal aorta.
- It is characterized by acute thrombosis of the terminal aorta.
- It requires emergency revascularization when the diagnosis is made.
- It is often associated with distal obstructive lesions.
- Patients often show signs of ischemia in the legs, and males may have difficulty maintaining a stable erection.
- The preferred surgical procedure is bypass with a prosthetic graft.

A. It is characterized by a combination of atherosclerotic and thrombotic occlusion of the terminal aorta.
B. It is characterized by acute thrombosis of the terminal aorta.
E. Patients often show signs of ischemia in the legs, and males may have difficulty maintaining a stable erection.
F. The preferred surgical procedure is bypass with a prosthetic graft.
DISCUSSION: Leriche syndrome usually affects males 35 to 60 years of age. It is caused by a combination of thrombosis superimposed on atherosclerosis. The symptoms are usually those of ischemia of the legs, including weariness or claudication, atrophic changes, and the inability to maintain a stable erection owing to inadequate arterial flow to the penis.
Distal sites of segmental occlusion are not uncommon. This disorder is often tolerated well for 5—and even 10—years, but ultimately serious symptoms of ischemia require operation. The procedure of choice is a bypass with a prosthetic graft from the aorta to the iliac or femoral arteries bilaterally.
