Surgical management of popliteal artery entrapment syndrome.

Introduction: Popliteal artery entrapment syndrome (PAES) is a rare condition in which the popliteal artery becomes compressed by adjacent soft tissue structures causing progressive claudication. Due to its low incidence, this disorder and its surgical management is poorly described in the literature. This study presents our institutional data surrounding PAES management to further optimize care of this syndrome. Methods: This retrospective study gathered demographic, surgical, and outcome data of all patients with PAES who underwent surgical decompression at our institution from 2015 to 2022. Patients were identified using CPT and ICD-9/10 codes. Summary statistics were calculated, with Chi-squared and T-test used for subgroup analysis. Results: 50 surgical patients with PAES were identified. On average, they were young (mean age: 20.7 years), mostly female (78 %), and predominately white (68 %). The vast majority were physically active, with 13 of the 50 patients being runners (26 %). Medically, the cohort was otherwise healthy, with 74 % reporting no comorbidities. Diagnosis was often delayed, with patients on average seeing 4.5 physicians over 2.0 years prior to arriving at our institution for care. In addition to popliteal artery release, the second most performed procedure was fasciotomy (82 %). Postoperatively, there was significant long-term subjective improvement, with 91 % of patients reporting they would repeat the operation and 65 % reporting improved activity. Conclusion: PAES is a rare condition affecting the lower limb that requires a nuanced surgical approach. From diagnosis to outcome, we hope to better inform surgeons of PAES so that these patients may receive the highest quality care.
