The optimal approach to recanalization in acute ischemic stroke is unknown. We performed a literature review and meta-analysis comparing the relative efficacy of 6 reperfusion strategies: (1) 0.9 mg/kg intravenous tissue-type plasminogen activator; (2) intra-arterial chemical thrombolysis; (3) intra-arterial mechanical thrombolysis; (4) intra-arterial combined chemical/mechanical thrombolysis; (5) 0.6 mg/kg intravenous tissue-type plasminogen activator and intra-arterial thrombolysis; and (6) 0.9 mg/kg intravenous tissue-type plasminogen activator and intra-arterial thrombolysis.
Methods—A literature search in Medline, Embase, and the Cochrane database identified case series, observational studies, and treatment arms of randomized trials of anterior circulation arterial occlusion treated with thrombolytic therapy. Included studies had ≥10 subjects, mean time to treatment <6 hours, and treatment specific reporting of disability, death, and intracerebral hemorrhage. Multivariable metaregression evaluated the effects of treatment group on outcome at the same time as accounting for differences in baseline covariates. Read more
