Abstract
Basilar artery dolichoectasia can lead to ischemic stroke through thrombosis of small perforating vessels of the brainstem. Here we report the case of a patient with transient paramedian pontine syndrome in the setting of a hypertensive crisis, finding a dolichoectasia basilar artery compressing on the ventral surface of the pons. The outcome was near-complete resolution of deficits after blood pressure control. We propose increased basilar artery pulse pressure as a novel mechanism of transient compression of the brainstem by a dolichoectasia artery.
摘要
基底动脉延长扩张可导致脑桥小穿支血管血栓形成，从而引起缺血性脑卒中。在此我们报告了一例高血压危象患者出现短暂性旁正中脑桥综合征，发现基底动脉延长扩张压迫脑桥腹面。血压控制后，患者的症状几乎完全缓解。我们提出增加基底动脉脉搏压是延长扩张的动脉短暂压迫脑干的新机制。
