Vertebrobasilar dolichoectasia is defined as elongation, dilatation, and tortuosity of the basilar and vertebral arteries. We describe two patients with vertebrobasilar dolichoectasia, one who presented with acute posterior circulation infarct and subsequent arterial dissection, and the other who presented with acute posterior circulation infarct, arterial dissection, and hydrocephalus at presentation. These cases serve as a reminder of the clinical significance of the presence of vertebrobasilar dolichoectasia and its potential complications.

椎基底動脈延長擴張症是指椎動脈和基底動脈的異常延長、擴張和迂曲。本文描述椎基底動脈延長擴張症的兩個病例：其中一例起病為急性後循環梗塞，繼發動脈夾層；另一例症狀為急性後循環梗死、動脈夾層和腦積水。本報告指出椎基底動脈延長擴張症的臨床重要性以及其潛在的併發症。
