Digital subtraction angiography is regarded as the gold standard for the evaluation of aortoiliac and peripheral arteriosclerotic disease. However, it is invasive, and difficulties may be encountered during the evaluation of total occlusion of the infrarenal aorta. The rapid development of multi-detector-row computed tomography scanners has promoted the use of this modality for assessing the vascular system in a minimally invasive manner. We report a case of Leriche syndrome assessed using multide-tector-row computed tomography angiography as the diagnostic tool. The technique allows high-quality angiography-like images and provides adequate information necessary for surgical treatment.
