title: [Preliminary experiences of "Waffle cone" technique for the treatment of intracranial aneurysm].
abstract: OBJECTIVE
  To explore the preliminary experiences of "Waffle cone" technique for the treatment of intracranial aneurysm.
  
  
  METHODS
  Retrospective data analyses were performed for patients with intracranial aneurysms embolized by the "Waffle cone" technique from stent-assisted coiling at our hospital from December 2010 to November 2012.
  
  
  RESULTS
  Six patients used the "Waffle cone" technique from 138 stent-assisted coiling. All had complex wide-neck bifurcation cerebral aneurysms. And the angles between parental artery and distal vessels were acute. Six rupture aneurysms were at the terminus of basilar artery (BA) (n = 2), right anterior communicating artery (AcomA) (n = 3) and trifurcation middle cerebral artery (MCA) (n = 1). All stents were of Solitaire with specification 4×15 mm (ev3, USA) .Four patients had Raymond classification Class I while another 2 Class II. No perioperative complication occurred. The average follow-up period was 6 months.
  
  
  CONCLUSIONS
  This technique is safe, time-saving, simple and effective for complex, wide-necked bifurcation aneurysms with acute angles between parental artery and distal vessels.Long-term follow-ups are needed to further evaluate its efficacy.
