Question 5#

The preferred procedure for treatment of typical occlusive disease of the aorta and both iliac arteries is:

a. Endovascular stenting
b. Extra-anatomic bypass
c. Aortoiliac endarterectomy
d. Aortobifemoral bypass

Correct Answer is D


In most cases, aortobifemoral bypass is performed because patients usually have disease in both iliac systems. Although one side may be more severely affected than the other, progression does occur, and bilateral bypass does not complicate the procedure or add to the physiologic stress of the operation. Aortobifemoral bypass reliably relieves symptoms, has excellent long-term patency (approximately 70-80% at 10 years), and can be completed with a tolerable peri operative mortality (2-3%).
