Abstract:
Conventional CT and three-dimensional CT angiography (3D-CTA) were conducted after peripheral arterial bypass surgery on 17 patients (26 grafts) from October, 1994 to April, 1996. Seventeen grafts were patent. The following objectives were satisfied in these cases: 1. Prosthetic graft or saphenous vein was depicted by 3D-CTA, 2. The distal portion of the native artery was depicted by 3D-CTA, and 3. Opacification of the graft interior was recognized by transverse section of CT. Nine grafts were occluded but prosthetic grafts were depicted in 5 cases, and prosthetic grafts and the distal portions of native arteries in 3 cases. Opacification of the graft interior was not seen in any case. Achievement of the above three objectives was considered necessary to determine graft patency.
