Abstract:
Objective To evaluate the mid-and long-term follow-up outcome of revascularization and stenting of nonacute intracranial vertebrobasilar artery occlusion. Methods Consecutive data of 27 patients who suffered from nonacute intracranial vertebrobasilar artery occlusion beyond 24 hours and underwent endovascular revascularization, were retrospectively collected and analyzed. Complications and recurrent ischemic events during the follow-up period were recorded. The modified Rankin scale(mRS) scores were used and compared between pre-and postoperation. Results All 27 patients except one(96.3%) obtained successful recanalization. After the procedure, 13 patients showed improvement, 11 were stable, and 3 worse. The decline of median mRS scores, which was 4(interquarter range-IR, 2-5) preoperatively and 3(IR, 1-5) on discharge. Five patients suffered from procedural complications and three of them resulted in aggravation. Nineteen patients received imaging follow-up during the median 10 months, 6 restenosis occurred and 3 of them were symptomatic. During median 55 months clinical follow-up after operation, 2 ipsilateral stroke and 2 ipsilateral transient ischemic attack occurred. The mRS scores decreased significantly in the first one year after procedure. Conclusions Revascularization and stenting of nonacute intracranial vertebrobasilar artery occlusion can prevent recurrent ipsilateral ischemic event and improve disability recovery in the first one year.
