title: Clinical and Angiographic Outcomes of Wide-necked Aneurysms Treated with the Solitaire AB Stent.
abstract: OBJECTIVE
  This study investigated the clinical and angiographic outcomes of treatment with stent-assisted coil embolization using the Solitaire AB stents for wide-necked intracranial aneurysms.
  
  
  METHODS
  From October 2010 to December 2011, 22 patients with aneurysms were treated with the Solitaire AB stent. One patient with a dissecting aneurysm was excluded, thus 21 patients with 21 wide-necked saccular aneurysms were included in this study. The technical success rate, procedure-related complications, initial and follow-up angiographic results, and clinical outcomes were retrospectively collected.
  
  
  RESULTS
  THE LOCATIONS OF ANEURYSMS WERE AS FOLLOWS: paraclinoid in 14, distal internal carotid artery in 4, and vertebral artery in 3 patients. All aneurysms were unruptured and less than 10 mm-sized. The mean dome-to-neck ratio of the aneurysms was 1.00 (range: 0.45-1.81). The mean follow-up duration was 12.1 (7-15) months after the initial procedure. The technical success rate was 21 (95.5%) of 22 patients with aneurysms. Fortunately, there were no procedure-related complications. Follow-up angiography showed that the rate of complete occlusion was 57.1%, neck remnants 38.1%, and incomplete occlusion 4.8%.
  
  
  CONCLUSIONS
  We suggest that using Solitaire AB stent is technically feasible and safe in the stent-assisted coil embolization for wide-necked saccular intracranial aneurysms. To evaluate the long-term effects of this stent, further follow-up angiography is needed.
