Objective To evaluate the technical feasibility, safety and treatment effeciency of the acute and chronic occluded vertebrovacular artery endovacular recanalization.Methods Eleven patients with occluded vertebrovascular artery were treated.We recorded the variation of image and clinical manifestation,then analyzed the correlated dangerous elements and evaluated treatment effect by comparing the modified Rankin Scale scores and recanalizated bloodstream TIMI scores for all patients among preoperation,postoperation and following-up.Results Recanalization was successful in 9 of the 11 patients.During the periprocedure, 6 patients were stable, 3 patients improved,and 2 patients were worse.During the follow-up,7 patients improved, l patient remained stable, and 3 patient died or were not followed up.Median TIMI scores for occluded artery elevated from 1 to 3 (P < 0.05) after the treatment and the median modified Rankin Scale scores for preoperative, postoperative and 3 months following-up were respectively 5, 5(P > 0.05) and 4 (P > 0.05).Three patients had periprocedural complication and the rate was 27.3%.One with dissection of basilar artery and postoperative pons stroke,one with temples haematoma after arterial thromblysis and one with pons stroke with basilar artery stent.The prognosis of purely occluded intracranial vertebral artery recanalization maybe better with clinical improvement and lower complication rate.Conlusions Endovascular recanalization of the acute and chronic occluded vertebrobasilar artery was technically feasible.Clinical and radiographic improvements were observed especially from the purely occluded intracranial vertebral artery.Since high complication rate, careful screening and operation was needed.Strict indication should be established on clinical studies.
