为了比较家族性与非家族性自发性动脉夹层分离复发危险度,作者于1990～1996年对200例患有颅外颈内动脉或椎动脉自发性动脉夹层分离患者进行了2年随访。女104例,男96例,平均年龄44.9(16～76)岁。对其中189例(94.5％)作了详细的家族血管病调查,经过复习其影像学资料、住院和尸检记录、死亡证明等来确定是否患有动脉夹层分离。结果200例患者中有10例具有家族史,家庭中有1个或多个成员患有 In order to compare the risk of relapse between familial and non-familial spontaneous dissection, we performed a 2-year follow-up of 200 patients with extracranial internal carotid artery or vertebral artery dissection in 1990-1996. 104 females, 96 males, average age 44.9 (16 to 76) years old. Of 189 cases (94.5%) made a detailed family vascular disease survey, after reviewing its imaging data, hospitalization and autopsy records, death certificates to determine whether suffering from dissection of the dissection. Results Of the 200 patients, 10 had a family history and one or more members of the family had it
