Doppler US is excellent for classifying stenoses as above or below a single degree of severity but does not function well in stenosis subclassification.

A 50-year-old male diagnosed with Behçet's disease was referred to our department for stent graft treatment because of thoracic, abdominal, and right common iliac artery (CIA) aneurysms. He had a superior mesenteric artery aneurysm in 2005 that was treated with resection and bypass surgery through the radial artery. He later underwent four abdominal surgical procedures for conditions such as intestinal perforation and ileus. Stent graft treatment was performed. The postoperative course was uneventful; postoperative computed tomography (CT) showed no apparent endoleak, while that performed at 3 years post-discharge showed that the aneurysms had decreased in size.
