Review Meta Analysis
Systematic review of outcome after ischemic stroke due to anterior circulation occlusion treated with intravenous, intra-arterial, or combined intravenous+intra-arterial thrombolysis.
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. ⋯ This study found no evidence that one reperfusion strategy is superior with respect to efficacy or safety, supporting clinical equipoise between reperfusion strategies. Intravenous tissue-type plasminogen activator remains the standard of care for acute ischemic stroke. Randomized clinical trials are necessary to determine the efficacy of alternative reperfusion strategies. Participation in such trials is strongly recommended.
