Abstract:
Preoperative and postoperative evaluation was conducted on 25 patients (33 lesions) with arteriosclerosis obliterans (ASO) by three-dimensional CT angiography (3D-CTA) and intraarterial digital subtraction angiography (IA-DSA). The usefulness and problems of 3D-CTA for diagnosis of ASO were studied. Both methods had equal ability to detect lesions in the area of the iliac artery and the femoral artery. Totally occlusive lesions were accurately diagnosed by 3D-CTA, but diagnosis of stenotic lesions was much less accurate. To confirm blood flow following vascular reconstruction 3D-CTA was useful and IA-DSA was not required. 3D-CTA images can be obtained from desired directions and clearly detect calcification and blood clots with little health risk involved. They are useful for the diagnosis of ASO.
