Abstract：
Vertebrobasilar insufficiency is a condition characterized by poor blood flow through the posterior circulation of the brain, which supplies the brainstem, thalamus, hippocampus, cerebellum, occipital lobes, and medial temporal lobes. Narrowing or occlusion of the vertebral arteries may be result in a range of neurological symptoms, including dizziness, imbalance, dysarthria, and even stroke. If symptomatic patients fail medical management, revascularization of the vertebral artery should be considered. Restoration of blood flow may involve transluminal balloon angioplasty or stent placement; however, certain cases may still require surgical intervention. The complexity of surgical revascularization of the vertebral artery requires careful consideration of skull base and neck anatomy. This review article will focus on bypass of the vertebral artery in the setting of ischemic pathology, describing the technique, anatomical nuances, steps involved in preoperative planning, and postoperative management.
摘要：
椎基底动脉供血不足是一种通过大脑后循环的血流不良的疾病，供应脑干，丘脑,海马体,小脑,枕叶,内侧颞叶。椎动脉狭窄或闭塞可能会导致一系列神经症状，包括头晕,不平衡,构音障碍,甚至中风。如果有症状的患者医疗管理失败，应该考虑椎动脉血运重建.血流的恢复可能涉及经腔球囊血管成形术或支架置入；然而，某些病例可能仍需要手术干预。椎动脉血运重建手术的复杂性需要仔细考虑颅底和颈部解剖结构。本文将重点讨论在缺血性病理学背景下的椎动脉搭桥术,描述技术，解剖学上的细微差别,涉及术前计划的步骤，和术后管理。
