急性缺血性脑卒中按发生原因分为自发性出血性转化和继发性出血性转化。自发性出血性转化即出血性脑梗死,发生率为5%~10%(文献报告)或1.4%~7.3%(多项研究证实)或0~3.4%(汇总分析),溶栓后自发性出血性转化发生率为9%~12%(头颅CT证实)或10.0%~19.8%(多项研究证实),血管介入治疗后自发性出血性转化发生率为8.1%~37.0%,抗血小板聚集治疗和抗凝治疗后自发性出血性转化的发生率分别为4.0%~5.3%,和1.4%~13.0%。
According to the causes of acute ischemic stroke is divided into spontaneous hemorrhagic transformation and secondary hemorrhagic transformation. Spontaneous hemorrhagic transformation of hemorrhagic cerebral infarction, the incidence of 5% to 10% (reported in the literature) or 1.4% to 7.3% (confirmed by multiple studies) or 0 to 3.4% (pooled analysis), spontaneous thrombolysis The incidence of hemorrhagic transformation was 9% to 12% (head CT confirmed) or 10.0% to 19.8% (confirmed by multiple studies). The incidence of spontaneous hemorrhagic transformation after vascular intervention was 8.1% -37.0%, anti-platelet aggregation The rates of spontaneous hemorrhagic transformation after treatment and anticoagulation were 4.0% -5.3% and 1.4% -13.0%, respectively.
