N2 - Objectives: The purpose of this study was to report our experience with popliteal artery entrapment syndrome (PAES) with special emphasis on the applicability of duplex ultrasound scanning (DUS) when diagnosing PAES. In addition to examining the correlation between DUS and intraoperative findings in symptomatic limbs, the ultrasonic effect of plantar flexion in healthy volunteers were also evaluated. Methods: During a 12-month period, 11 symptomatic limbs in 8 patients with a mean age of 29 years were referred with suspected PAES and enrolled consecutively. The popliteal artery was studied preoperatively with DUS in rest and during active plantar flexion. The popliteal artery was explored in all symptomatic limbs, and the intraoperative findings served as gold standard. Additionally, the popliteal arteries in 11 healthy volunteers (22 limbs) were evaluated with DUS during rest and plantar flexion. Results: Intraoperative findings confirmed PAES in all 11 symptomatic limbs in accordance with the preoperative DUS examination. Surgical release of the popliteal artery was performed in 11 limbs. At a median follow-up of 15 months, all 11 limbs were free of ischemic symptoms and regained normalized popliteal flow on DUS. In the 22 symptom-free limbs, DUS showed normal popliteal flow during both rest and plantar flexion. Conclusions: In this series of patients with surgically confirmed PAES, we found preoperative DUS to have perfect agreement with the intraoperative findings in diagnosing PAES. The applicability of the method seems to be emphasized by the restoration of popliteal flow and relief of arterial insufficiency after surgical release in all patients, and by the fact, that none of the healthy volunteers were able to compress the popliteal artery during plantar flexion.
