【摘要】 脑侧支循环的建立对于缺血性卒中的预后至关重要,便捷有效的脑侧支循环评估方法对于临床预测卒中患者预后、血管再通治疗效益与风险评价尤为重要。TCD因其可实时检测脑血流动力学指标、无创伤、可重复、操作便捷、廉价等优点在脑侧支循环评估中发挥着不可替代的作用。本文检索文献就TCD对脑一、二级侧支循环和脑血管反应性的检测方法、意义及临床应用进展进行综述,以期为临床诊疗提供帮助。更多还原

【Abstract】 Cerebral collateral circulation is crucial for the prognosis of patients with acute ischemic stroke(AIS). The assessment of cerebral collateral circulation can guide the selection of treatment strategy. TCD is a convenient and effective method of evaluating collateral circulation. TCD can detect cerebral hemodynamic indexes in real-time, in addition, it has non-invasive, repeatable, convenient operation and low-priced advantages. Therefore, TCD plays an important role in diagnosis and treatment of AIS. This article reviewed the detection methods and clinical value of TCD for primary and secondary collateral circulation and cerebrovascular reactivity in ischemic stroke, to provide some reference for diagnosis and treatment of AIS.更多还原
