Iatrogenic femoropopliteal graft entrapment leading to thrombus formation.
Femoropopliteal bypass graft entrapment by the gastrocnemius muscle and tendons is an unusual cause of graft stenosis or thrombosis. Before graft occlusion occurs, reduced flow may be seen either with the knee in extension or hyperextension or by passive dorsiflexion of the ankle. We report a case of a femoropopliteal bypass graft entrapment causing a thrombus in the distal graft. Duplex imaging, angiography, MRI and graft surveillance programs are useful diagnostic tools. Treatment options include dividing the occluding muscles and tendons and rerouting the graft.
