title: [Endovascular repair for isolated iliac artery aneurysm].
abstract: OBJECTIVE
  To evaluate the short and middle-term efficacies of endovascular repair for isolated iliac artery aneurysms (IIAAs).
  
  
  METHODS
  Retrospective analyses were performed for the clinical and follow-up data of 27 patients undergoing endovascular repair at Department of Vascular Surgery, Affiliated Zhongshan Hospital, Fudan University from January 2008 to December 2012. For asymptomatic aneurysms, repair criterion was a diameter over 3 cm while under 3 cm for symptomatic aneurysms.
  
  
  RESULTS
  There were 19 asymptomatic and 8 symptomatic cases. And 25 selective and 2 emergent operations were performed. The interventions included endovascular stent grafts (n = 17), coil embolization (n = 1), both stent grafts and coils (n = 7) and hybrid operations (n = 2). Technical success was achieved in all cases. No delayed healing or infection of inguinal access sites occurred. In-stent thrombosis could be observed in 2 cases. Buttock claudication was observed in one case. Sexual dysfunction occurred in three cases. Endoleaks were confirmed by intraoperative digital subtraction angiography in three cases. There was no occurrence of colorectal ischemia or postoperative aneurysmal rupture. Patients were followed up for a mean period of 33 ± 18 months. One patient died of recurrent renal cell carcinoma.
  
  
  CONCLUSIONS
  Endovascular repair of isolated iliac artery aneurysms provides good short and middle-term patency. It may become a first-choice for treating isolated iliac artery aneurysms in the future.
