鈍的外傷による椎骨動脈損傷の経験

Blunt Injury of the Vertebral Artery: Report of three cases

I．はじめに

　鈍的外傷による頸動脈損傷は現在まで多数報告されているが，椎骨動脈損傷の報告は少ない^1-32）．今回，われわれは鈍的外傷により椎骨動脈損傷をひきおこし，さらに小脳および脳幹梗塞を来たした3症例を経験したので報告する．また，過去の報告例と自験例と合わせて，本症の診断，治療および予後について考察したい．

The authors reported three cases, whose vertebral arteries had been injured by blunt trauma to the neck which was followed by cerebellobrainstem infarctions.

Case 1: a 32-year-old man, who developed severe vertigo and nausea 7 days after a traffic accident. He showed neck pain and horizontal nystagmus on admis-sion. Three days later, he became drowsy. CT scan of the head demonstrated right-side cerebellar infarction, and the angiography revealed an occlusion of the right vertebral artery at C^4-5 level.
