出血性脑梗塞Hemorrhagic Infarction以下简称HI,是指缺血性中风病人由于梗塞区血流再通而发生出血,近年来,随着抗凝和溶栓治疗并发症之——继发性脑出血的被重视,再度引起人们对HI的关注。一、HI的病因 HI的病例报告,国内不到二百例,而国外尸检报告新近发生的脑梗塞病人30％是HI,对中风病人回顾性研究发现,初期CT检查没有出血改变的病人中11～42％在三周内发展为HI。常见的病因有:1.栓塞性中风。病理研究发现栓塞性中风病人发病率51～71％;非栓塞性中风病人HI发病率2～21％。病理证实的HI比CT发现的多,可能与CT对小病灶尤其是点状出血的检出率较低有关。在栓
Hemorrhagic Infarction Hemorrhagic Infarction, hereinafter referred to as HI, refers to the ischemic stroke patients due to blood flow in the infarct area and bleeding, in recent years, with anticoagulant and thrombolytic treatment of complications - secondary cerebral hemorrhage Being taken seriously, once again aroused the concern of the people of HI. First, the cause of HI HI case report, less than 200 domestic cases, and foreign autopsy reported 30% of recent cerebral infarction was HI, a retrospective study of stroke patients found no change in the initial CT examination of patients with bleeding 11 ~ 42% to HI within three weeks. Common causes are: 1. Embolic stroke. Pathological studies found that the incidence of embolism stroke patients 51 to 71%; non-embolic stroke HI incidence of 2 to 21%. Histologically confirmed HI more than CT found may be related to the small CT detection of small lesions, especially spot detection rate is low. In the bolt
