lCLINICAL INVESTIGATION l Long-term Results of Endovascular AAA Repair Using a Homemade Aortomonoiliac PTFE Device

l l Purpose: To assess the long-term results of a homemade aortomonoiliac polytetrafluoro-ethylene (PTFE) device used for endovascular abdominal aortic aneurysm (AAA) repair. Methods: A vascular audit database was interrogated to identify 58 consecutive AAA pa-tients (all men; median age 73 years, range 56–88) who underwent aortomonoiliac stent-graft repair. AAAs were eligible for endovascular treatment if the infrarenal neck was $15 mm long and #28 mm in diameter. Results: Nine (15.5%) procedures failed, 8 during the procedure and 1 on the 7th postop-erative day; 8(13.8%) patients were converted, but one was unfit for surgery. There was one intraprocedural stroke, and 3 (5.2%) patients died within 30 days. The primary success rate (no conversion or mortality) was 79.3%. Over a median follow-up of 45 months (range 23–80), there were 3 (5.2%) graft occlusions, 1 kink requiring stent implantation, and 1 expanding sac without identifiable endoleak. There were 11 (19.0%) endoleaks in 10 pa-tients, 9 type I leaks (2 proximal) and 1 type II. One patient with a distal type I endoleak (treated) also exhibited a type III leak at 2 years, but the sac size had not increased. Ther
