“…[15][16][17][18] Additionally, involvement of the popliteal vein is more varied and cannot be confined to one type with coexistent arterial involvement. 10,15,[18][19][20][21][22][23][24][25][26][27] Such variation was also encountered in our practice and prompted the review of ability of the CC system to capture all patients with PES. Shortcomings in the CC system on such review instigated us to design an all-inclusive new classification.…”

Objectives To assess the ability of the current classification system for popliteal entrapment syndrome to accurately capture all patients, and if not, to design an all-inclusive new classification. Methods Retrospective review of all interventions performed for popliteal entrapment syndrome between 1994 and 2013 at our institution was performed. Preoperative imaging and intraoperative findings were used to establish the compressive morphology of popliteal entrapment syndrome. Patients were categorized, when possible, into six types of the current classification system (Rich classification, modified by Levien) and into seven types of a new classification. Results Sixty-seven limbs of 49 patients were operated on for unilateral (31) or bilateral (18) popliteal entrapment syndrome. The current classification system captured the anatomy of only 43 (64%) of 67 limbs with popliteal entrapment syndrome. Compressive morphologies without a defined class included aberrant insertion of the lateral head of gastrocnemius muscle, muscle slip originating from the lateral head of gastrocnemius or hamstrings, hypertrophied hamstring muscle, abnormal fibrous bands, perivascular connective tissue, and prominent lateral femoral condyle. The new classification captured 100% of the limbs with popliteal entrapment syndrome. Conclusions Current classification of popliteal entrapment syndrome is inadequate as more than one-third of the cases reviewed fell outside of the standard classification system. Consideration of a more inclusive new anatomic classification system is warranted.

“…6 Other causes include popliteal artery aneurysms, hypertrophied fibrous bands, 2 thickened perivenous fascia, 4 popliteal adventitial cystic disease, ruptured popliteal cysts, 7 as well as one case report identifying an aberrantly high branching medial sural artery resulting in compression of the posterior tibial vein. 8 Although not all people with PVE develop symptoms; the femoral-popliteal venous system may have a duplicated segment not involved in the entrapment, as seen in 10% of patients. 9 Therefore, are other characteristics and risk factors, such as thrombophilias, long haul flights, or the oral contraceptive pill, required to become symptomatic?…”
