Popliteal Entrapment Syndrome: 1

A D V E R T I S E M E N T

   
 

A 22-year-old male presented with bilateral calf claudication after undergoing lower extremity fasciotomies. He had no palpable pulses below the femorals and bilateral ankle-brachial indices in the .50-.60 range. Angiogram revealed bilateral popliteal abnormalities with normal proximal vessels. There was occlusion on the right and stenosis on the left with left post stenotic dilatation. Distal runoff of reconstituted vessels was poor bilaterally. Popliteal entrapment syndrome is a condition found in young people with calf and foot claudication and must be differentiated from systemic vascular disease and chronic compartment syndrome. The latter results from increased compartment pressures and was initially suspected in this patient.

Popliteal Entrapment Syndrome: 2

The popliteal artery is a short vital conduit between the adductor hiatus and the lower border of the popliteus muscle. The neurovascular bundle consisting of artery, vein and tibial nerve descends and passes between the heads of the gastrocnemius muscle and pass through a hiatus in the upper portion of the soleus muscle. Abnormalities at both sites can impinge on the vessels, but the more common pathology involves the gastrocs.

Popliteal entrapment is a rare condition first described by a Scottish medical student, T. P. Anderson Stuart, in 1879. Five variations have been described. In type I, the popliteal artery passes in a wide loop medial to and under a normal medial gastroc head. The vein remains in its normal position.
