摘要
椎基底动脉延长扩张症（vertebrobasilar dolichoectasia，VBD）可使卒中风险增高。椎基底动脉显著延长、扩张和弯曲是VBD的主要形态学表现，但对VBD的影像学量化评估尚缺乏统一认识。一些研究显示，基底动脉弯曲长度和理论长度、基底动脉成角和椎动脉迂曲指数等量化指标可用于VBD的影像学量化评估。
Vertebrobasilar dolichoectasia（VBD ） can increase the risk of stroke. Significant expansion, elongation and tortuosity of the vertebrobasilar arteries are the main morphology manifestations of VBD. However, there is no consensus on the quantitative imaging assessment of VBD. Many studies showed that some quantitative parameters, such as basilar artery length and bending length, basilar angulation, vertebral tortuosity index can be used for the quantitative imaging assessment of VBD.
