Abstract

Variations in the popliteal artery and its tibial branches are common and have assumed greater importance with the technological advances that have made below-knee interventional revascularization feasible. The authors report a rare anatomic variant of popliteal artery agenesis, describing the CT angiographic findings with emphasis on the differential point from the occlusive disease and reviewing the embryologic development of the lower extremity vasculature.

  Fig. 1 CT angiographic images of a 48-year-old man with bilateral popliteal artery agenesis. A, B. Maximum intensity projection (A) and volume rendering (B) images in posterolateral projection show bilateral popliteal arteries ended gradually as prominent muscular branches (thick arrows). Notice abundant collateral arteries (arrowheads) reconstituting a distal portion of a popliteal artery (thin arrows) on both sides. C. Axial images show (a) normal P1 segment, (b, c) absent popliteal artery above the knee, and (d) reconstituted P3 vessel (arrows) on both sides. Gastrocnemius muscles (asterisks) are normal.
