过去常认为:脑缺血甚或脑梗塞是大脑中动脉或其他颅内动脉闭塞的结果。但是,近十年来的观察及研究,使这种看法已经发生改变。很多学者已经认识到颈动脉和椎动脉的动脉粥样硬化是脑缺血或脑梗塞的重要因素。此外,广泛应用脑血管造影,以及造影部位包括颈部的方法。确实发现了更多的颈动脉闭塞的病人。目前,国内对这方面的报导不多,综合国内资料(3-7,27),共有47例无脉病的报告,其中以脑部缺血为主要表现且症状严重者有13例,只有8例无脉病(7,27)作了主动脉造影,其中5例、见到颅
Used to think: cerebral ischemia or even cerebral infarction is the result of occlusion of the middle cerebral artery or other intracranial arteries. However, the observations and studies of the past decade have changed this view. Many scholars have realized that atherosclerosis of the carotid and vertebral arteries is an important factor of cerebral ischemia or cerebral infarction. In addition, extensive use of cerebral angiography, as well as the imaging area including the neck method. Indeed found more carotid artery occlusion patients. At present, there are not many reports in this field in our country. According to the domestic data (3-7, 27), there are 47 reports of no pulse-free disease. Among them, 13 cases are characterized by severe cerebral ischemia and only 8 Cases without pulse disease (7,27) made aortic angiography, of which 5 cases, to see the skull
