Abstract

Abstract Aim Popliteal artery aneurysms (PAAs) are increasingly treated via an endovascular approach. We present mid-term outcomes of popliteal endovascular aneurysm repair (PEVAR) from a single centre. Method A retrospective analysis of a prospective database of consecutive patients who underwent either elective or emergency PEVAR in a single regional vascular centre from January 2010 to August 2020. The patients underwent placement of a heparin-bonded stent-graft (Viabahn Endoprosthesis, WL Gore and Associates, Flagstaff, USA) for PAA >20mm or complications: thromboembolism, rupture or popliteal vein thrombosis. Patency and stent-graft related complications were assessed. Results A total of 64 PAAs (mean size 36.8±13.4mm) were treated in 56 patients (mean age 75±10.7 years, 54 (96%) male). Median follow-up was 29.5 months (IQR 36.75). 30-day mortality was 0%. Technical success rate of stent-graft insertion was 100%. 1-year and 5-year primary patency was 83% and 67% respectively; primary-assisted patency at these time points was 86% and 72%, and the corresponding secondary patency was 89% and 75%. 61 out of 64 treated limbs had >1 vessel runoff. The most frequently occurring complication was stent-graft occlusion which affected 11 (17%) limbs. Stent-graft fracture occurred in 1 patient, resulting in endoleak. Conclusions Viabahn Endoprosthesis can be used successfully in treatment of PAA with acceptable short- and mid-term patency rates. One in five patients in this cohort required a reintervention, with most complications occurring in the first year postoperatively. Stent-graft fracture occurred only in one patient demonstrating that PEVAR is a safe option for PAA management in the intermediate term.
