缺血性脑血管病是因某种原因,脑血流量减少,引起的脑功能障碍。在临床上可分为如下四种类型:短暂性脑缺血发作(TIA),可逆性脑缺血性神经功能障碍(RIND),进行性脑卒中(PS),完全性脑卒中(CS)。在美国每年死于脑血管病变的20万人中,90%是由缺血性脑血管病引起,10%是出血性疾病。缺血性脑血管病约有2/3是颅外血管病变、颈内动脉血栓性闭塞;颅内血管病变中约有1/4是大 Ischemic cerebrovascular disease is due to some reason, decreased cerebral blood flow, caused by brain dysfunction. Clinically, it can be divided into the following four types: TIA, RIND, PS, CS. Of the 200,000 people who die of cerebrovascular disease each year in the United States, 90% are caused by ischemic cerebrovascular disease and 10% are hemorrhagic diseases. About 2/3 of ischemic cerebrovascular disease is extracranial vascular disease, thrombotic occlusion of the internal carotid artery; about 1/4 of intracranial vascular disease is large
