出血性转化（hemorrhagictransformation，HT）是指急性缺血性卒中后血管恢复血流灌注时发生的脑内出血，是缺血性卒中的常见并发症之一。 HT 可无临床表现，也可表现为肢体瘫痪加重、意识水平下降等症状。有症状HT 可导致住院时间延长以及残疾率和病死率增高。因此，研究HT的机制和危险因素有望为临床治疗提供依据，进而改善患者预后。文章对HT 的形成机制、危险因素、高危患者的筛选和防治等进行了综述。

Hemorrhagictransformation(HT)referstointracerebralhemorrhageoccurredwhenthe blood vessels restore blood flow after acute ischemic stroke. It is one of the common complications of ischemic stroke. HT may not have any clinical manifestations and can also be manifested as limb paralysis aggravation, decreased consciousness level, and other symptoms. The symptomatic HT may result in prolonged hospitalization, increased disability and fatality. Therefore, research on the mechanisms and risk factors for HT may be expected to provide the basis for clinical treatment, and thus improve the prognosis of patients. This article review s the formation mechanism of HT, risk factors, screening of high-risk patients, and prevention and treatment.
