Sixteen patients having infarction caused by circulatory disturbance at the top of the basilar artery, that is to say, the "top of the basilar" syndrome, were studied, the diagnosis having been made by computerized tomography. Infarcts were widely distributed in each patient between the thalamus, midbrain, pons, cerebellum, and occipital lobe. Both thalami were involved in 7 cases. When the thalamus was involved bilaterally, the low density areas were symmetrical in size and localization. Angiography revealed that stenosis or occlusion lay within a circle 2 cm in diameter surrounding the five-forked junction at the top of the basilar artery in 84.6%. Recanalization of the occluded artery occurred in 61.5%, suggesting that embolism played an important role in appearance of this syndrome.
对16例由基底动脉顶端循环障碍所致梗死，即“基底动脉顶端”综合征的患者进行了研究，诊断通过计算机断层扫描做出。梗死灶在每位患者的丘脑、中脑、脑桥、小脑和枕叶之间广泛分布。7例双侧丘脑均受累。当双侧丘脑受累时，低密度区在大小和位置上是对称的。血管造影显示，84.6%的患者在基底动脉顶端五叉交界处周围直径2 cm的范围内存在狭窄或闭塞。61.5%的闭塞动脉发生再通，提示栓塞在该综合征的发生中起重要作用。
