缺血性脑卒中亦称脑梗塞,系由脑供血障碍使脑组织缺血、缺氧引起脑软化,为临床难治疾病。脑卒中是人类死亡的三大原因之一,而缺血性脑卒中约占全部脑卒中的43～65％。其发病率与死亡率远较其他脑卒中为高。据统计,每10万人口中每年死于缺血性脑卒中者大约120人左右,而脑出血仅为40人,故其重要性是脑血管病的首位。对本病的预防与正确的诊断、治疗无疑对延长人类寿命、减少死亡率是极为重要的。一、病因最主要的为高血压病、脑动脉硬化症、急性低血压、动脉炎以及血液病、外伤等,但以高血压病与动脉粥样硬化为最重要。动脉粥样硬化斑块,动脉硬化引起的血管扩张、 Ischemic stroke, also known as cerebral infarction, is caused by cerebral blood supply disorders so that brain tissue ischemia, hypoxia caused by brain softening, is a clinical refractory disease. Stroke is one of the top three causes of human death, while ischemic stroke accounts for about 43-65% of all strokes. Its morbidity and mortality is far higher than other stroke. According to statistics, every year about 100,000 people die of ischemic stroke each year about 120 people, and only 40 cerebral hemorrhage, so the importance of cerebrovascular disease is the first place. The prevention of the disease and the correct diagnosis and treatment are undoubtedly the extension of human life expectancy, reduce mortality is extremely important. First, the most important cause of hypertension, cerebral arteriosclerosis, acute hypotension, arteritis and blood diseases, trauma, but with hypertension and atherosclerosis is the most important. Atherosclerotic plaques, atherosclerosis-induced vasodilation,
