Background Popliteal artery aneurysms (PAAs) are relatively rare but are one of the most common peripheral arterial aneurysms. Open popliteal artery aneurysm repair (OPAR) has been the standard, but technological advancements have made endovascular popliteal artery aneurysm repair (EPAR) a promising alternative. The aim of this study is to compare EPAR and OPAR efficacy and outcomes over a 10-year period. Methods This study retrospectively reviewed 72 patient charts who were diagnosed with PAA or popliteal artery pseudoaneurysm and underwent EPAR or OPAR from 1 January 2010 to 31 December 2019. Endovascular popliteal artery aneurysm repair was used in 37 cases and OPAR in 35 cases. Results Graft patency 90 days postoperative was 72.73% in the EPAR group and 82.35% in the OPAR group (p = 0.477). Graft patency >2 years postoperative was 81.25% in the EPAR group and 86.67% in the OPAR group (p = 0.682). Freedom from reoperation 30-day postoperative was 78.38% in the EPAR group and 80% in the OPAR group (p = 0.865). Freedom from amputation 30-day postoperative was 91.43% in the EPAR group and 94.29% in the OPAR group (p = 0.263). The 30-day survival rate was 94.59% in the EPAR group and 100% in the OPAR group. Conclusions Endovascular repair represents a promising alternative for PAA repair. Our results demonstrate that EPAR has similar outcomes for asymptomatic, acutely symptomatic, and chronic symptomatic patients. Technological advancements of stent properties and refinement of surgical techniques may further improve endovascular techniques.
