ABSTRACT
Objective To evaluate the efficacy and safety of intra-arterial thrombolysis with recombinant tissue-plasminogen ac-tivator(rt-RA) for treatment of acute cerebral infarction (ACI) .Methods The randomized controlled trials (RCT ) of intra-arterial thrombolysis with rt-PA for treatment of ACI were selected from Cochrane Library ,Medline ,Embase and CBM by the computer re-trieval .A meta analysis of the data were analyzed by using RevMan 5 .1 software .Results A total of 473 patients in 9 selected RCTs were involved in the systematic review .Meta-analysis results disclosed suggested that the effectiveness of intra-arterial thrombolysis treated ACI group was better than that of intravenous thrombolysis group [RR= 1 .26 ,95% CI(1 .09 ,1 .45) ,P=0 .002] .No difference was observed between the two groups in intracranial hemorrhage and mortality rate .Conclusion The current evidence showed that ,the clinical effect of intra-arterial thrombolysis with rt-PA for treatment of ACI was obviously superior to that of intravenous thrombolysis ,but the result still needs to be confirmed by large-sample RCTs .
