Popliteal artery entrapment syndrome (PAES) surgery is safe and effective for limb ischemia. Surgical decompression and revascularization offer favorable outcomes, with most patients remaining symptom-free long-term.
Area of Science:
- Vascular Surgery
- Orthopedic Surgery
- Anatomy
Background:
- Popliteal artery entrapment syndrome (PAES) is a rare condition caused by abnormal popliteal artery anatomy.
- It can lead to limb ischemia due to compression by surrounding musculoskeletal structures.
Purpose of the Study:
- To present a case series of PAES patients treated surgically.
- To evaluate the safety and effectiveness of surgical interventions for PAES.
Main Methods:
- Retrospective review of 12 PAES patients (2012-2023) at a single academic center.
- Diagnosis confirmed by pulse volume recordings with dynamic maneuvers and imaging.
- Surgical decompression, with or without arterial revascularization, was performed.
Main Results:
- 13 limbs affected, predominantly PAES type I and III.
- Intermittent claudication was the most common symptom.
- High primary patency rate (92.3%) and 83.3% asymptomatic patients at median 70.5-month follow-up.
Conclusions:
- Surgical treatment for PAES is safe and effective.
- Favorable mid-term outcomes with low morbidity are achievable.
- Early diagnosis and multidisciplinary care are crucial for optimal results.
