title: Evaluation of recanalisation treatment on posterior circulation ischemic stroke by Solitaire device-A multicenter retrospective study.
abstract: OBJECTIVE
  Posterior circulation ischemic stroke (PCIS), accounting for approximately 20% of total ischemic stroke, is a sever disease that associated with high rate of morbidity and mortality. Though the effectiveness of endovascular mechanical thrombectomy has been well demonstrated in many types of ischemic stroke, it is still unclear what the outcome is in posterior circulation ischemic stroke.
  
  
  METHODS
  In current study, data was collected from 139 Chinese patients who received endovascular mechanical thrombectomy treatment with Solitaire device after acute posterior circulation ischemic stroke. We measured the mortality, symptomatic intracranial hemorrhage (SICH) and National Institutes of Health Stroke Scale (NIHSS) to evaluate the safety of endovascular mechanical thrombectomy. Meanwhile, the clinical outcome of endovascular mechanical thrombectomy was also evaluated based on recanalisation rate, HIHSS, and the modified Rankin Scale (mRS).
  
  
  RESULTS
  Recanalisation was successful in 124 (89.3%) patients after surgery. Herniation was the second fatal stroke complication, out of the 6 patients suffered from herniation, 3 patients (50%) died during surgery and 2 (33%) died after surgery. As for other stroke complications such as pulmonary infection, 1 patient (4.3%) died during surgery and 1 patient (4.3%) died 3 days after surgery.
  
  
  CONCLUSIONS
  Our findings indicate that endovascular mechanical treatment is a safe treatment which brings clear benefit to patients suffered from posterior circulation ischemic stroke, in both the recanalisation rate and functional outcomes.
