      consecutive patients.

AB  - BACKGROUND AND PURPOSE: There are a few reports regarding the outcome evaluation 
      of balloon-expandable intracranial stent placement (BEICS). The purpose of our 
      study was to evaluate the outcome and factors related to the adverse events (AEs) 
      of BEICS. MATERIALS AND METHODS: We evaluated 100 consecutive patients who 
      underwent BEICS. We assessed the procedural success (residual stenosis < 50%), 
      AEs (minor strokes, major strokes, and death), clinical outcome, and restenosis 
      (> 50%) at 6 months. We also analyzed 18 factors including symptom patterns 
      related to AE rate. Symptom patterns revealed 1) stable patients (n = 73) with 
      improving, stationary, or resolved symptoms; and 2) unstable patients (n = 27) 
      with gradual worsening or fluctuating symptoms (National Institutes of Health 
      Stroke Scale [NIHSS] > or = 4) within 2 days before stent placement. RESULTS: The 
      procedural success rate was 99%. Overall, there were 10 (10%) AEs within the 6 
      months: 4 (4%) minor strokes, 3 (3%) major strokes, and 3 (3%) deaths including a 
      death from myocardial infarction. AE rate was 4.1% in stable and 25.9% in 
      unstable patients. Restenosis at 6 months revealed 0% (0/59). Good outcome 
      (modified Rankin Scale < or = 2) at 6 months was 97% (71/73) in stable and 67% 
      (18/27) in unstable patients. Stepwise logistic regression model revealed that 
      symptom pattern (unstable versus stable) was the only significant risk factor 
      (OR, 8.167; 95% CI, 1.933-34.500; P = .004). CONCLUSION: BEICS revealed a low AE 
      and good outcome rate at 6 months, especially in the stable patients. Midterm 
      outcome was also favorable in the unstable patient group.
