Radiological and clinical findings of 20 cases with angiographically proven stenosis or occlusion of the vertebrobasilar system and with clinical signs and symptoms attributable to posterior circulation disorder were studied. A simplified classification of vertebrobasilar arterial disease was presented; type I refers to stenosis of the vertebrobasilar system or subclavian artery, type II refers to vertebrobasilar occlusion, and type III refers to vertebrobasilar branch disease. Type I lesions were further subdivided into types Ia and Ib; type Ia cases showed no infarction in the posterior territory, whereas type Ib cases showed one or more infarctions on computed tomography or magnetic resonance imaging. This angiographic classification is based on treatment options that can be adopted to specific types of lesion. In type I cases, lesions are usually amenable to surgical or angiographic intervention. In type II cases, short-term anticoagulation is the treatment of choice. In type III cases, treatment is primarily aimed at prevention of complication and further stroke.
对20例经血管造影证实存在椎基底动脉系统狭窄或闭塞且伴有后循环障碍临床体征和症状的患者的放射学及临床发现进行了研究。提出了一种简化的椎基底动脉疾病分类；I型指椎基底动脉系统或锁骨下动脉狭窄，II型指椎基底动脉闭塞，III型指椎基底动脉分支疾病。I型病变进一步细分为Ia型和Ib型；Ia型病例在后循环区域无梗死，而Ib型病例在计算机断层扫描或磁共振成像上显示一处或多处梗死。这种血管造影分类基于可针对特定类型病变采用的治疗方案。在I型病例中，病变通常适合手术或血管造影干预。在II型病例中，短期抗凝是首选治疗方法。在III型病例中，治疗主要旨在预防并发症和进一步的中风。
