title: Long-term results of aortouniiliac stent grafts for the endovascular repair of abdominal aortic aneurysms.
abstract: BACKGROUND
  Long-term follow-up of patients with aortouniiliac (AUI) grafts is lacking in the current literature. The purpose of this study was to review the outcomes of endovascular aneurysm repair (EVAR) using commercially available AUI devices with femorofemoral bypass in patients whose aortoiliac anatomy was unfavorable for bifurcated repair.
  
  
  METHODS
  A retrospective review of 35 patients from September 2000 to February 2012, who underwent EVAR with commercially manufactured AUI devices, was performed. These comprised 35 of 372 (9.4%) patients who underwent EVAR during that period. Patient records were reviewed to determine morbidity, mortality, and survival after AUI repair. Patients were followed at 1-, 3-, 6-, and 12-month intervals with computed tomography (CT) scans during each visit. Median follow-up was 40 months (range: 2-135 months).
  
  
  RESULTS
  Median age at surgery was 76 years (range: 60-93). The median preoperative aneurysm diameter was 57 mm (range: 45-71) and the median postoperative diameter was 53 mm (range: 29-80). Two type II endoleaks occurred on 1-month CT, whereas 10 endoleaks (type I [3], II [6], and III [1]) occurred during follow-up after 1 month. Migration of the stent graft occurred in 9% (n=3). Secondary procedures were required in 26% (n=9), whereas tertiary procedures were required in 3% (n=1). One patient required treatment for thrombosis of the iliac extension and 2 required treatment for thrombosis of the femorofemoral component. Mortality over the follow-up period was 34% (n=12) with no deaths occurring within 30 days.
  
  
  CONCLUSIONS
  High-risk patients who present with aortoiliac anatomy unsuitable for bifurcated stent graft placement should be offered AUI graft placement as a potential alternative to open repair.
