Figure 2. In case 7, (a) segmental leg pressure examination showed absence of Doppler waveform at both calf and ankle levels. (b) Transfemoral angiogram revealed complete thrombotic occlusion of the right common iliac artery, left superficial and deep femoral arteries. Note that the abdominal aorta showed normal anatomy and luminal patency without evidence of atherosclerosis. (c) Histopathologically, the femoral artery was almost totally occluded by the organized thrombi (haematoxylin and eosin stain, x 40). The arterial wall showed no pathological abnormalities.
