AB  - BACKGROUND: Endovascular recanalization and stenting has been used to treat 
      patients with symptomatic nonacute intracranial vertebrobasilar artery occlusion 
      (VBAO) refractory to aggressive medical treatment. This study was performed to 
      analyze the perioperative complications of the procedures. METHODS: Between 
      February 2010 and March 2012, 27 consecutive patients (24 men, 3 women; age: 57 +/- 
      10 years) with symptomatic, nonacute intracranial VBAO including 12 basilar 
      artery occlusions and 15 vertebral artery occlusions were collected and 
      retrospectively analyzed. RESULTS: The median time between symptom onset and 
      recanalization was 1.5 months (interquartile range [IQR]: 0.7-3.4) and between 
      imaging-documented occlusion and recanalization was 9.5 days (IQR: 6-18 days). 
      Recanalization was achieved in 96% of patients (26/27). Five (5/27; 19%) 
      perioperative complications occurred. Two patients had dissections: 1 dissection 
      resulted in termination of the procedure without successful recanalization, and 
      the other was handled by the placement of 2 stents. There was 1 intraprocedural 
      acute thrombosis that was successfully treated with balloon angioplasty. One 
      patient experienced thrombus disruption and translocation during the procedure: 
      thrombus was dislodged after disruption by the guidewire. There was 1 acute 
      reocclusion after procedure: while recanalization was achieved again, there was 
      no improvement in clinical outcome. CONCLUSIONS: This study revealed that 
      recanalization and stenting for nonacute VBAO may be technically feasible but 
      that it is accompanied by a high risk of complication. The causative factors for 
      perioperative complications need future study.
