Bilateral popliteal artery entrapment syndrome with asynchronous onset.

Popliteal artery entrapment syndrome is recognized as a cause of lower leg claudication in patients younger than 50 years of age. We report a rare case of a patient with bilateral popliteal artery entrapment who presented with the same symptom 11 years after his first experience of popliteal artery entrapment syndrome. On both occasions, the surgery was performed in a similar manner and the patient was free from symptoms after the surgery. Since the diagnosis of popliteal artery entrapment syndrome is difficult, early detection of popliteal artery entrapment syndrome is important to prevent its progression.
