Retrospectively, 51 patients who related two or more signs or symptoms of vertebrobasilar insufficiency and possessed concomitant carotid arterial disease were identified. The patient population was separated into two groups based on the presence or absence of an angiographically visualized posterior communicating artery during selective carotid artery injection. All patients had undergone unilateral or staged bilateral carotid endarterectomy. Comparison of postoperative clinical outcome with intracerebral angiographic findings exhibited statistically significant improvement in favor of those patients with at least one visualized posterior communicating artery. There was a greater likelihood of severe vertebral artery stenosis in those patients whose symptoms were not relieved by carotid endarterectomy.
回顾性研究发现，51例患者出现了两个或更多椎基底动脉供血不足的体征或症状，且伴有颈动脉疾病。根据选择性颈动脉注射造影时是否存在血管造影可见的后交通动脉，将患者人群分为两组。所有患者均接受了单侧或分期双侧颈动脉内膜切除术。将术后临床结果与脑内血管造影结果进行比较，结果显示，至少有一条可见后交通动脉的患者在统计学上有显著改善。那些症状未通过颈动脉内膜切除术缓解的患者，发生严重椎动脉狭窄的可能性更大。
