Intraarterial thrombolytic therapy decreases mortality in the treatment of acute basilar artery occlusion. An acute decrease in cerebral blood flow (CBF) (<12 mL/100 g per minute) has been reported to invariably result in infarction. We report a case of acute basilar artery occlusion, recanalized within 90 minutes, with reversal of CBF of less than 6 mL/100 g per minute. After reperfusion, areas with persistent CBF of 6 mL/100 g per minute resulted in infarctions on subsequent CT studies. Parenchymal viability is possible after 90 minutes of posterior CBF of 6 mL/100 g per minute.
动脉内溶栓治疗可降低急性基底动脉闭塞的死亡率。据报道，脑血流量（CBF）急性减少（<12毫升/100克每分钟）必然会导致梗死。我们报告一例急性基底动脉闭塞病例，在90分钟内实现再通，CBF逆转至低于6毫升/100克每分钟。再灌注后，CBF持续为6毫升/100克每分钟的区域在后续CT研究中出现梗死。在CBF为6毫升/100克每分钟的情况下，90分钟后仍有可能实现实质存活。
