title: Stent-jail technique in endovascular treatment of wide-necked aneurysm.
abstract: OBJECTIVE
  To describe a reconstructive technique using single stent for wide-necked aneurysms.
  
  
  METHODS
  This technique was described as stent-jail technique consisting of the aneurismal catheterization before the deployment of a self-expandable stent across the aneurysm neck. Following the deployment of the stent, embolization coils were delivered with the microcatheter positioned within the aneurysm dome and wedged between the stent and the aneurysm dome. The microstents, such as Neuroform, Leo and Wingspan stents, were used in in our series for electively treated aneurysms.
  
  
  RESULTS
  During a 3-year period,13 patients with wide-necked aneurysms were treated electively with this technique. The aneurysms arose from the internal carotid artery (5), anterior cerebral artery (4), anterior communicating artery (1), vertebral artery ( 1), middle cerebral artery (1) and middle cerebral artery (1). Thirteen stents (6 Leo stents, 4 Neuroform stents and 3 Wingspan stents) were successfully deployed across the aneurysm neck to constrain subsequent embolization coils of a wide-necked cerebral aneurysm. None of the patients experienced any periprocedural or delayed neurological complications. This maneuver enabled us to support the coil loops within the aneurismal sac with stabilization of the microcatheter.
  
  
  CONCLUSIONS
  The stent-jail technique represents an efficacious adjuvant technique to assist coiling of selected wide-necked cerebral aneurysms. This technique is particularly helpful for wide-necked aneurysms.
