Objectives: To investigate the therapeutic effects of intravenous thrombolysis, intra-artery thrombolysis, mechanical thrombectomy on patients with acute vertebrobasilar occlusion. Methods: Retrospective analysis of clinical data of patients with acute vertebrobasilar occlusion, admitted to Huai'an First People's Hospital and Bingtuan Qishi Hospital from January 2014 to January 2016, was performed. According to different vascular recanalization, these patients were divided into intravenous thrombolysis group, intra-artery thrombolysis group and mechanical thrombectomy group. Clinical outcomes were compared among the three groups such as recanalization rates( modified thrombolysis in cerebral infarction[mTICI]≥2b), changes of NIHSS scores after 24 hours(scores decreased at least 4 points or complete resolution of symptoms), symptomatic cerebral hemorrhage rate(European Cooperative Acute Stroke Study Ⅱ standard) and modified Rankin scale(mRS) score improvement 3 months after treatment. Results: Among patients from mechanical thrombectomy group, the recanalization rate was 87.5%(28/32), 22 patients(68.8%)got good outcome according to the significant decrease of NIHSS scores, symptomatic intracranial hemorrhage occurred in 3 patient (9.4%), the rate of good prognosis(mRS≤2) at 3 months was 50.0% (16/32). In patients from intravenous thrombolysis group, the rate of recanalization was 34.8% (16/46), 12 patients(26.1%)got apparent decrease of NIHSS scores, symptomatic cerebral hemorrhage occurred in 14 patients(30.4%), the rate of good clinical outcome(mRS ≤2) at 3 months was 17.4%(8/46). Among patients from intra-arterial thrombolysis group, the recanalization rate was 53.3%(16/30), 12 patients(40.0%) got good outcome according to the significant decrease in NIHSS score, symptomatic intracranial hemorrhage occurred in 6 patients(20.0%), the rate of good prognosis(mRS≤2) at 3 months was 26.7%(8/30). The rate of complete recanalization and NIHSS score improvement at 24 hours were significantly higher in the mechanical thrombectomy group than the intravenous or intra-arterial thrombolysis group(χ(2)=21.324, P<0.001; χ(2)=14.162, P=0.001). The good outcome(mRS≤2) at 3 months was more frequent in the mechanical thrombectomy group than the intravenous or intra-arterial thrombolysis group (χ(2)=9.799, P=0.007). The differences of symptomatic intracranial hemorrhage rate among the three treatment groups were not statistically significant(χ(2)=5.035, P=0.081). Conclusion: As compared with the intravenous or intra-arterial thrombolysis, the mechanical thrombectomy has better efficiency and safety in the treatment of acute vertebrobasilar occlusion.
