Figure 1: Case no. 1. (a–c) Multidetector computed tomography (MDCT), maximum intensity projection, and three-dimensional images of the infragenicular arteries show total occlusion of the left popliteal artery (red arrows), which is seen extending for a segment measuring 8.7 cm in length, poor collateral circulation is seen with only a short segment of the left posterior tibial artery (PTA) seen patent with contrast, and absent flow in the anterior tibial artery. Almost no flow could be seen in the left foot. (d–g) Corresponding MDCT axial images: (d) axial image at the level of the popliteal artery; (e) axial image at the level of the anterior tibial artery, PTA, and peroneal artery; (f and g) axial images at the level of foot. All these images confirm total occlusion of the left popliteal artery (red arrow) and absent flow in the anterior tibial and peroneal arteries. Almost no flow could be seen in the left dorsalis pedis; however, the corresponding arteries in the contralateral side are seen patent (orange, green, and yellow arrows, respectively).
