Three surgically treated cases of popliteal entrapment syndrome are reported. Two of the patients were consanguineous. This unusual syndrome is caused by an anomalous relationship between the popliteal artery and the musculature in the popliteal fossa. Arterial compression usually results in ischaemic calf pain. Popliteal entrapment syndrome seems to be underdiagnosed. Pathogenesis, diagnosis and treatment are discussed.

Popliteal vein entrapment must be taken in consideration in patients with symptoms of venous insufficiency. Leg edema, swelling, calf pain, and muscle cramps are all unspecific signs. Most patients thus far have presented with deep vein thrombosis or chronic venous insufficiency. Popliteal entrapment syndrome must be taken into account in younger patients in whom predisposing factors are absent and chronic calf swelling is notable. Diagnosis is easily confirmed by noninvasive stress testing with duplex imaging and pencil Doppler probe placed over the posterior tibial artery. Additionally, digital subtraction angiography with the foot in neutral and dorsi plantarflexion is recommended for arterial entrapment. Surgery is advisable for treatment and can be done without significant morbidity. In asymptomatic patients, we suggest using the term "popliteal vein entrapment phenomenon." We describe different etiologies of popliteal vein entrapment in three cases and present a review of the literature.

Popliteal entrapment syndrome caused by isolated popliteus muscle enlargement is very rare, although its occurrence has been reported after discrete trauma. However, popliteal artery stenosis with combined peroneal and proximal tibial neuropathy caused by popliteus muscle enlargement without preceding trauma has not been reported. A 57-year-old man presented with a tingling sensation and pain in his left calf. He had no previous history of an injury. The symptoms were similar to those of lumbosacral radiculopathy. Calf pain became worse despite treatment, and the inability to flex his toes progressed. Computed tomography angiography and magnetic resonance imaging of the lower extremity showed popliteal artery stenosis caused by popliteus muscle enlargement and surrounding edema. An electrodiagnostic study confirmed combined peroneal and proximal tibial neuropathy at the popliteal fossa. Urgent surgical decompression was performed because of the progressive neurologic deficit and increasing neuropathic pain. The calf pain disappeared immediately after surgery, and he was discharged after the neurologic functions improved.
