急性缺血性脑卒中（AIS）采取再灌注治疗后，引起出血转化（HT）的情况虽不常见，但严重影响患者预后和神经功能恢复。目前研究较多的HT机制包括缺血损伤、缺血再灌注、阿替普酶带来的凝血功能异常及血-脑屏障破坏。通过认识临床危险因素和应用预测模型及多模态影像学检查等手段可以实现对HT的早期发现和早期预防。未来使用新型溶栓药物及新研发的脑保护剂有望进一步控制HT转化率和改善患者预后。本综述总结HT的分类、病理生理学机制、危险因素、预测因子和预测模型，以及相应治疗，以及时发现，更好预防，同时针对性地给予个体化治疗，尽可能降低严重并发症的危害，提高AIS患者再灌注治疗后血管再通获益率及降低神经功能损害，促进预后。

After reperfusion therapy for acute ischemic stroke (AIS), the hemorrhagic transformation caused by reperfusion is uncommon, but it seriously affects the prognosis and neurological recovery of the patients. At present, the mechanisms of bleeding transformation that have been extensively studied include ischemia injury, ischemia reperfusion, coagulation dysfunction caused by Alteplase (rt-PA), and destruction of blood-brain barrier. The early detection and prevention of hemorrhagic transformation (HT) can be achieved through recognizing clinical risk factors and applying predictive models and multimodal imaging. Future use of novel thrombolytic drugs and newly developed brain protectants is expected to control HT conversion further and improve patients' outcomes. This review summarizes the classification, pathophysiological mechanisms, risk factors, predictors and predictive models, and corresponding treatment of HT, for timely recognizing and prevention, and at the same time, individualized treatment should be given to reduce the harm of serious complications as far as possible, and improve the benefit rate of vascular recanalization in AIS patients after reperfusion therapy and reduce the neurological function damage to promote the prognosis.
