Abstract

Objective: This study documents mid-term outcomes of a series of endovascular popliteal aneurysm repairs compared with concurrent results of open surgical repair. Methods: A retrospective chart review was done of all popliteal artery aneurysm repairs since January 1, 2000. Patency was defined as continued presence of palpable pulses or maintenance of postoperative ankle-brachial index ± 0.15. Statistical methods included χ2, t test, Fisher's exact test, and Kaplan-Meier plots with log-rank comparison. Results: A total of 56 popliteal artery aneurysm repairs were performed. All endovascular popliteal aneurysm repairs (EVPAR, n = 15) were performed using Viabahn endoprostheses. Patients with open repair (OR, n = 41) underwent surgical bypass and aneurysm exclusion with great saphenous vein (n = 26), short saphenous vein (n = 3), or polytetrafluoroethylene (n = 12), through either a medial (n = 28) or posterior (n = 13) approach. All urgent cases received open repair. Technical success was 100% in both groups. Mean follow-up was 16.5 ± 3 months (range, 0.5 to 56 months). Aneurysm size, location, and outflow were similar between groups. Primary patency, secondary patency, and survival did not differ between groups. Endoleaks were observed in three (20%) of 15 endovascular cases, and type I and III endoleaks were treated with additional endografts. Conclusion: To our knowledge, this represents the largest United States series of EVPAR to date. Early mid-term results of elective endovascular repair of popliteal artery aneurysms are encouraging. Further studies are warranted to define optimal indications for EVPAR and to generate long-term outcomes for this technique.
