脑血管病分布受种族的影响.根据文献资料黑人和日本人的颅内闭塞性脑血管病多见,而白人则以颅外病变高发.在中国,尽管卒中的发病率高,但有关华人闭塞性血管病的分布情况则很少研究.本文对24例自人和24例华人症状性闭塞性脑血管病的临床与放射学特征进行了比较.结果发现与华人相比,白人组有较高的过去TIA发生率(58%∶25%,P=0.02),且血小板计数高(317,000∶246,000,P=0.025).临床方面,两组 The distribution of cerebrovascular disease is affected by race.According to the literature, black and Japanese are more common in patients with intracranial occlusive cerebrovascular disease, while whites are more likely to have extracranial disease.In China, although the incidence of stroke is high, The distribution of vascular disease is seldom studied.In this paper, the clinical and radiological features of 24 patients with symptomatic obliterative cerebrovascular disease in 24 Chinese and 24 Chinese were compared.The results showed that compared with Chinese, the white group had higher (58%: 25%, P = 0.02) and high platelet count (317,000: 246,000, P = 0.025) .In the clinical field, two groups
