title: Results of endovascular treatment for intracranial wide-necked saccular and dissecting aneurysms using the Enterprise stent: a single center experience.
abstract: OBJECTIVE
  The aim of the present retrospective study is to compare outcome of the endovascular treatment using the Enterprise stent in intracranial wide-necked saccular and dissecting aneurysms.
  
  
  METHODS
  Forty-six patients with 50 complex intracranial aneurysms admitted between June 2009 and November 2010 were treated using Enterprise stents. Thirty-one aneurysms were wide-necked saccular, 19 aneurysms dissecting. In 48 cases, aneurysms were occluded by stent-assisted coiling; in 2 cases, by stent alone.
  
  
  RESULTS
  Among the aneurysms treated with the Enterprise stent, patient sex, aneurysm location, hypertension history and the immediate angiographic results differed significantly between the saccular and dissecting aneurysm groups. However, recurrence rate, clinical follow-up outcomes did not differ significantly between the saccular and dissecting groups. There was 1 (2%) procedure-related complication, which caused death in the saccular group. At mean 9.1-month follow-up, the result was good in all dissecting cases and good in 30 saccular cases. There was 1 recurrence in each group.
  
  
  CONCLUSIONS
  Enterprise stent is very useful for endovascular embolization of intracranial wide-necked saccular and dissecting aneurysms because it is easy to navigate and place precisely. The overall morbidity and mortality rates were low.
