Objective To observe the effect of mechanical recanalization of acute basilar artery occlusion and investigate the feasibility and safety of mechanical recanalization for acute basilar artery occlusion.Methods A retrospective analysis of clinical data of seven patients with acute basilar artery occlusion who have accepted mechanical recanalization in past 4 years,and analyze the postoperative immediate effect and prognosis.Results Seven patients have achieved mechanically opened, 3 patients wih stenosis >50% have accepted stent angioplasty. 1 case wih stenosis <50% have not accepted stent angioplasty. 3 patients wih atrial fibrillation have no stenosis. 2 patients died of bleeding,1 patient has plant survival and another 4 patients have good recovery. MRS scores of 5 survivors respectively 3 months later:1 point in 1 case, 2 points in 1 case, 3 points in 2 cases, 5 points in 1 case.Conclusions Mechanical recanalization of acute basilar artery occlusion has a high success rate, overall results were satisfactory and is an effective and reliable treatment for acute basilar artery occlusion.
