摘　　要：目的探讨椎基底动脉延长扩张症(vertebrobasilar dolichoectasia,VBD)的临床表现及诊断方法。方法回顾2例典型椎基底动脉延长扩张症患者临床及影像学资料,并结合文献进行分析。结果VBD具有时间顺序占位效应,面肌痉挛、低钾、三叉神经痛、眩晕发作、肢体偏瘫相继发生,VBD具有进展性。结论VBD症状多样,具有时间顺序,面肌痉挛可能是较早出现的症状。部分后循环缺血(posterior circulation ischemia,PCI)症状可能仅仅是VBD脑干压迫的结果,而不是传统意义上的PCI。Objective To explore the clinical presentation and diagnosis of vertebrobasilar dolichoeetasia （VBD） presented with brainstem compression symptoms. Methods Clinical and imaging data of 2 typical cases of Vertebrobasilar dolichoectasia were retrospectively analyzed and relevant literature was reviewed. Results Hemifaeialspasm, hypokalemic paralysis, trigeminal neuralgia, vertigo, hemiplegia progressively occurred in a chronological order due to the extension of VBD. Conclusions VBD can cause to a variety of symptoms in a chronological order and early hemifaeialspasm may be a hint for early diagnosis of VBD. Posterior circulation ischemia （PCI） may result from VBD.
