A26-year-old man was suffered a tendon injury in the left knee when playing American football 3years previously and was treated consevatively. He was admitted to our hospital because of coldness and paresthesia in the left leg since 2 months previously. Femoral angiogram revealed severe stenosis of left popliteal artery and occlusion of the anterior and posterior tibial artery. CT and MRI examination revealed a tumor which protruded into the lumen of the left popliteal artery or dissection of left popliteal artery. Operation was performed by a posterior approach. The left popliteal artery was not compressed from the lateral side and there was a white thrombus in the popliteal artery. Thromboendartherectomy and autologus venous patch plasty was done. Histopathological findings of the stenotic lesion revealed an organizing thrombus, chiefly consisting of fibrin, and intima both of which were infiltrated by granuration tissue. It was suggested that the stenotic lesion was caused by arterial wall hyperplasia or thrombus formation during the healing process after blunt arterial injury. The post-operative course was uneventful.
