Popliteal artery entrapment syndrome is the condition caused due to pressing of the popliteal artery by the calf muscles. This may be due to enlargement or abnormal positioning of the calf muscles. The condition was described in the year 1879 by Stuart. The surgical intervention for this condition was reportedly done 80 years later.

The author of the research study wrote, “The aim of this study was to evaluate the 5-year outcomes of surgical management for PAES and to investigate whether patency is affected by the initial extent of the arterial lesion.”

All the patients suffering from popliteal artery entrapment syndrome and undergone surgery between January 2003 and December 2009 were included in the study. The researchers recorded the clinical features, imaging results, demographic data, and surgical management. 5-year patency was considered as the primary outcome.

18 patients (25 limbs) underwent the surgery. The mean age of the patients at the time of surgery was 35 years. 39% of the patients had a bilateral presentation. Various methods in these patients were used to diagnose the condition. These were position stress tests, magnetic resonance imaging, duplex ultrasonography, computed tomography angiography, and conventional angiography. 16% of the limbs had compressed and undamaged popliteal arteries. The treatment in these patients was limited to musculo-tendinous division alone. Venous interposition was performed in 64% of the limbs in which the popliteal artery was damaged with lesions limited to the popliteal artery. 20% of the limbs have an injury that extends beyond the popliteal artery. The doctors performed below-knee femoro-popliteal bypass in limb, femoro-posterior tibial bypasses in three limbs, and popliteo-posterior tibial bypass in one limb. In 90% of the limbs, the musculo-tendinous division was associated with vascular reconstruction. The mean follow-up of the study was 82 months. Five-year patency was 84%.
