Objective: The aim of this study was compare elective surgical repair of popliteal artery aneurysms (PAAs) via a posterior approach vs. endovascular exclusion, analysing early and five year outcomes in a multicentre retrospective study. Methods: Between January 2010 and December 2023, a retrospectively maintained dataset of all consecutive asymptomatic PAAs that underwent open repair with posterior approach or endovascular repair in 37 centres was investigated. An aneurysm length of ≤ 60 mm was considered the only inclusion criterion. A total of 605 patients were included; 440 PAAs (72.7%) were treated via a posterior approach (open group) and the remaining 165 PAAs (27.3%) were treated using covered stents (Endo group). Continuous data were expressed as median with interquartile range. Thirty day outcomes were assessed and compared. At follow up, primary outcomes were freedom from re-intervention, secondary patency, and amputation free survival. Secondary outcomes were survival and primary patency. Estimated five year outcomes were compared using log rank test. Results: At 30 days, no differences were found in major morbidity, mortality, graft occlusion, or re-interventions. Three patients (0.7%) in the open group experienced nerve injury. The overall median duration of follow up was 32.1 months. At five year follow up, freedom from re-intervention was higher in the open group (82.2% vs. 68.4%; p = .021). No differences were observed in secondary patency (open group 90.7% vs. endo group 85.2%; p = .25) or amputation free survival (open group 99.0% vs. endo group 98.4%; p = .73). A posterior approach was associated with better survival outcomes (84.4% vs. 79.4%; p = .050), and primary patency (79.8% vs. 63.8%; p = .012). Conclusion: Early and long term outcomes following elective repair of PAAs measuring ≤ 60 mm via a posterior approach or endovascular exclusion seem comparable. Nerve injury might be a rare but potential complication for those undergoing open surgery. Endovascular repair is associated with more re-interventions.
