title: Aortoiliac aneurysms: management with endovascular stent-graft placement.
abstract: OBJECTIVE
  To evaluate endovascular stent-graft placement for management of aortoiliac aneurysms.
  
  
  METHODS
  Balloon-expandable stents covered with polytetrafluoroethylene were placed in 11 aortoiliac lesions in nine male non-surgical candidates (mean age, 63.5 years). There were six abdominal aortic aneurysms, four iliac artery aneurysms, and one acute pseudoaneurysm from a ruptured iliac artery. Stent-grafts were dilated up to 14 mm (iliac) and 24 mm (aorta). Patients underwent follow-up computed tomography and angiography.
  
  
  RESULTS
  Stent-grafts were successfully placed in all 11 cases. There were two complications: a ruptured iliac artery treated with placement of an additional covered stent and a lower-extremity vessel embolization and bowel infarction resulting in death. All stent-grafts remained patent without increased aneurysmal diameter. Three leaks (27%) were detected. Two leaks were treated with placement of additional covered stents. One still is asymptomatic.
  
  
  CONCLUSIONS
  Endovascular treatment of aortoiliac aneurysms with stent-graft devices may be an alternative to surgery.
