BACKGROUND: Enthusiasm for endovascular therapies has led to the use of stent graft repairs for popliteal artery @entity439 . In this report, we review our experience with this technique. METHODS: A retrospective review was performed of all @entity438 repairs (EVPARs) performed by the vascular surgery group at a tertiary care medical center. @entity1 demographic data, operative details, and outcomes were examined. RESULTS: We performed 33 EVPARs in 28 @entity1 . All @entity1 were male with a mean age of 76  years (range, 60-91). Mean @entity439 diameter was 3.2  cm (range, 1.5-6.3). All repairs were performed using a self-expanding covered stent graft. Among the @entity1 , 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 @entity1 including: stent oversizing leading to in-folding, perforation of a tibial artery, access site @entity1410 , and access vessel dissection. CONCLUSION: As experience with EVPAR continues to grow, caution must be applied in its use. Careful @entity1 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.
