小脳・視床梗塞を併発した特発性椎骨動脈解離の1治療例

Spontaneous Extra-cranial Vertebral Artery Dissection Accompanied with Multiple Cerebral Infarctions due to Re-canalization

Ⅰ．はじめに

　今回われわれは，何の誘因もなく椎骨動脈の解離閉塞を来し，再開通による多発脳梗塞を併発した症例を経験した．さらに，この特発性椎骨動脈解離に対してステント留置による血行再建術を経験したので，報告する．

In this paper we report a case of vertebral artery occlusion caused by spontaneous extra-cranial vertebral artery dissection accompanied with cerebellar and thalamic infarctions due to recanalization. Furthermore, after a nine-week time lapse we performed PTAistenting. A 62-year-old man with vertigo, dysarthria and nuchal pain without in-jury was admitted to our hospital. Emergent cerebral angiography revealed an occlusion of the right vertebral artery and the right PICA. The patient's symptoms gradually improved owing to local-fibrinolysis with urokinase for the right PICA via the left vertebral artery.
