Treatment of Popliteal Artery Entrapment Syndrome

Diagnostic Confirmation Before Treatment

• Surgical decompression should be performed immediately upon diagnosis for all anatomic types to prevent progressive arterial wall degeneration and occlusion, while functional PAES requires surgery only if symptomatic, as recommended by the American College of Cardiology 1
• Obtain duplex ultrasound with dynamic maneuvers as the initial test to visualize flow disturbances and vessel caliber changes in real-time, as suggested by the American College of Cardiology 1
• Confirm diagnosis with MR angiography to define complete popliteal fossa anatomy and evaluate dynamic changes during plantar flexion, as recommended by the American College of Cardiology 1
• Measure ankle-brachial index at rest and post-exercise, as significant drops indicate functional impairment requiring intervention, according to the American College of Cardiology 1

Treatment Algorithm by Clinical Presentation

For Acute Thrombosis with Poor Runoff

• Restore distal vessels before definitive repair by performing catheter-directed thrombolysis or mechanical thrombectomy to restore runoff vessels, as recommended by the American College of Cardiology 2
• This prevents catastrophic outcomes seen when repair is attempted without adequate distal targets, with a persistent ischemia rate of 56% and amputation rate of 19%, as reported by the American College of Cardiology 2

Postoperative Management

• Initiate antiplatelet therapy and continue indefinitely after revascularization, as recommended by the American College of Cardiology 3
