摘要
急性缺血性脑卒中最有效的治疗是再灌注治疗(溶栓、机械取栓或支架术等)。在可挽救的缺血脑组织进展梗死以前通过恢复其血流量,再灌注治疗可挽救缺血半暗带组织、减少最后梗死面积、改善临床结果。重组组织型纤溶酶原激活剂(rt-PA)静脉溶栓是目前惟一一种证实有效的治疗急性缺血性脑卒中的药物。虽然溶栓治疗日趋成熟,但标准的静脉溶栓治疗(非增强计算机断层扫描(CT)引导下、3h内、静脉注射tPA,)有许多限制,包括治疗时间窗短、血管再通率只有50%和症状性出血转变的重大危险等。结果,目前在临床实践中只有少数患者(通常是1%至3%)接受溶栓治疗。所以有一些问题仍需进一步探讨,如扩大溶栓时间窗、新的溶栓药物用于发病3h以上的急性缺血性脑卒中患者、评价各种新的再灌注方法(特别是多模式影像学技术)、静脉和动脉内药物溶栓联合应用、溶栓和新型抗小板药的联合应用,以及应用机械装置或经颅多普勒超声促进药物溶栓的作用等。
