脑血管烟雾病即Moyamoya病,又称脑底动脉闭塞伴异网形成。新近认为是脑血管疾病中的一单独类型,是引起蛛网膜下腔出血的重要病因之一。该病的特征是脑底部单侧或双侧颈内动脉床突上段狭窄或闭塞,同时在基底节部位有一特殊的毛细血管扩张网形成。临床表现与发病年龄有关,20岁以下的以发作性肢体无力或偏瘫多见;20岁以上的则以蛛网膜下腔出血多见。1961年以来国外报导逐渐增多,1973年Lee氏首次报导了中国人的病例11例,1976年河南医学院报告4例,我院曾收治6例,现结合文献简要报告和讨论如下: 病例资料六例临床表现的特点,血管造影的发现及其治疗结果,见附表:
Cerebrovascular moyamoya disease is Moyamoya disease, also known as cerebral artery occlusion with abnormal network formation. Recently considered as a separate type of cerebrovascular disease, is one of the important causes of subarachnoid hemorrhage. The disease is characterized by stenosis or occlusion of the superior segment of the unilateral or bilateral internal carotid artery at the base of the brain with a special capillary dilatation network at the basal ganglia site. Clinical manifestations and age of onset, under 20 years of age to episodes of limb weakness or hemiplegia more common; more than 20 years of age with subarachnoid hemorrhage more common. Since 1961, foreign reports have gradually increased. In 1973, Lee’s first report of 11 Chinese cases in 1976, Henan Medical College in 4 cases reported in our hospital had 6 cases, are now combined with the literature briefing and discussion are as follows: Cases of clinical manifestations of the characteristics of angiography findings and treatment results, see Schedule:
