Abstract

Background Enthusiasm for endovascular therapies has led to the use of stent graft repairs for popliteal artery aneurysms. In this report, we review our experience with this technique. Methods A retrospective review was performed of all endovascular popliteal artery aneurysm repairs (EVPARs) performed by the vascular surgery group at a tertiary care medical center. Patient demographic data, operative details, and outcomes were examined. Results We performed 33 EVPARs in 28 patients. All patients were male with a mean age of 76 years (range, 60-91). Mean aneurysm diameter was 3.2 cm (range, 1.5-6.3). All repairs were performed using a self-expanding covered stent graft. Among the patients, 18% were symptomatic at the time of repair. The median number of stents used was 2 (range, 1-4). Median duration of stay was 1 day (range, 0-12). The 1-year and 2-year patency were 87% and 81%, respectively, with a mean follow-up of 23 months. Loss of patency was associated with both poor distal runoff (P =.007) and increasing number of stents used (P =.03). Early complications were seen in 4 patients including: stent oversizing leading to in-folding, perforation of a tibial artery, access site hematoma, and access vessel dissection. Conclusion As experience with EVPAR continues to grow, caution must be applied in its use. Careful patient selection, proper operative technique, and correct vessel sizing are required for good outcomes. Poor distal runoff and use of numerous stents leads to diminished patency rates.
