Staged bilateral release of the popliteus muscle using a posterior surgical approach to the popliteal fossa to treat type 4 popliteal artery entrapment.

Popliteal artery entrapment syndrome (PAES) is a rare cause of intermittent claudication in the young. Aberrant embryological development results in entrapment of the popliteal artery by myofascial structures of the popliteal fossa. Type 4 PAES is due to aberrant development of the popliteus muscle superficial to the popliteal artery. We present a case of bilateral type 4 PAES, along with intraoperative photography highlighting the anatomical cause for this pathology. Both limbs in this patient were treated successfully with surgical release of the entrapping popliteus muscle via a posterior surgical approach to the popliteal fossa. This report emphasises the importance of determining popliteal artery integrity and entrapment subtype to guide the management of this condition.
