Surgical Treatment of Functional Popliteal Artery Entrapment Syndrome: Short- and Mid-Term Results

Functional popliteal artery entrapment syndrome (FPAES) is a rare and under-diagnosed clinical entity characterized by dynamic compression of the popliteal artery during exercise in the absence of a visible anatomic abnormality at rest. It preferentially affects young, otherwise healthy athletes (3,4). Although surgical release is the reference treatment, the literature relies mainly on small case series, surgical management is poorly standardized, and data on early post-operative morbidity (complications, re-hospitalization) are often lacking. This prospective, single-center, non-interventional study aims to describe the safety of the surgical management of FPAES as performed in routine care in the vascular surgery department of Ambroise Paré Hospital (AP-HP), a national reference center for this condition. The primary endpoint is the rate of re-hospitalization within 30 days of surgery. Secondary objectives address risk factors for re-hospitalization, minor adverse events, and the clinical and functional outcome of patients, including return to sport, assessed using the Lower Extremity Functional Scale (LEFS).
