本文目的在于检验用动脉内膜切除术治疗椎基动脉供血不足(VBI)的效果。复习了1969～1982年经治疗成功或失败的病例的血管造影解剖所见,并试图确定颈动脉内膜切除术对治疗 VBI 是否有益。全组51例(女21,男30)于术前均作了血管造影(包括选择性脑内摄片),后均作了单侧或双侧颈动脉内膜切除术,术后平均随访24个月。24例(男13,女11)血管造影若可见至少有一支后交通动脉(列属 A 组),另27例(男17,女10)无后交通动脉(列属 B 组)。每例血管造影分级:(1)按颈动脉内径缩小的百分比以及有无溃疡性斑块;(2)根据有无椎动脉病变,并
The purpose of this paper is to examine the efficacy of endarterectomy for vertebrobasilar insufficiency (VBI). A review of angiographic anatomy from 1969 to 1982 in cases of successful or unsuccessful treatment was reviewed and it was attempted to determine whether carotid endarterectomy was beneficial for the treatment of VBI. The whole group of 51 patients (21 female, 30 male) underwent angiography (including selective intracranial radiography) before surgery, both were unilateral or bilateral carotid endarterectomy after an average follow-up of 24 Months. 24 cases (male 13, female 11) angiography if there is at least one posterior communicating artery (included in group A), and the other 27 cases (male 17, female 10) without posterior communicating artery (included in group B). Each angiography grade: (1) according to the percentage of carotid artery diameter reduction and whether the ulcerative plaque; (2) according to the presence or absence of vertebral artery disease and
