title: Comparison of Stent-Assisted Coiling and Balloon-Assisted Coiling in the Treatment of Ruptured Wide-Necked Intracranial Aneurysms in the Acute Period.
abstract: OBJECTIVE
  The purpose of this study was to compare the efficacy, stability, and safety of stent-assisted coiling (SAC) and balloon-assisted coiling (BAC) in the treatment of ruptured wide-necked aneurysms in the acute period.
  
  
  METHODS
  Consecutive patients including 65 cases treated with SAC and 32 with BAC were reviewed at the authors' institution between November 2011 and December 2014. The efficacy of these 2 approaches and the incidence of periprocedural complications were retrospectively evaluated.
  
  
  RESULTS
  Morphologic analysis showed a lower fundus/neck ratio (1.2 vs. 1.6) in the aneurysms treated with SAC versus BAC (P < 0.001). The mean neck width of aneurysms was 4.0 mm in the patients treated with SAC versus 3.4 mm in those treated with BAC (P < 0.04). Coil protrusion into the parent vessels during embolization was an independent risk factor for cerebral ischemic events (odds ratio [OR], 4.08; 95% confidence interval [CI], 1.03-16.2). Neck width (OR, 0.65; 95% CI, 0.44-0.97) and aneurysm perforation during procedure (OR, 6.24; 95% CI, 1.21-32.3) were independent predictors of complete occlusion (Raymond 1) by immediate postembolization angiography. There was no statistical difference between the 2 techniques regarding the rate of aneurysm occlusion at the end of procedure, periprocedural complications, and favorable outcome at discharge and follow-up.
  
  
  CONCLUSIONS
  These findings suggested that SAC was more appropriate than BAC for ruptured wide-necked aneurysms with lower fundus/neck ratio or wider neck size. However, periprocedural complications, occlusion rates, and favorable outcomes did not differ between the 2 techniques.
