剣道防具による"Rubbing injury"で生じた解離性内頸動脈瘤の1例

Carotid Dissecting Aneurysm due to Blunt (Rubbing) Injury of KENDO's Protector

I．はじめに

　閉鎖性頸動脈損傷のmortalityおよびmorbidityは20-40％と報告されており_17），稀な外傷ではあるが，正確な認識を要するものといえよう．われわれは従来報告のない発生機序による外傷性解離陸内頸動脈瘤の治療例を経験したので報告し，最近の本病態に対する考え方を整理しながら考察を加える．

A case of dissecting aneurysm of the cervical in-ternal carotid artery due to rare mechanism by non-penetrating injury is descrived.

A 45-year-old right-handed man had complaints of the right lateral neck pain during exercise of KENDO wearing a tight headneck protector. Following sudden dysarthria and left hemiplegia, he developed loss of consciousness and generalized convulsion. Five hours after admission, he became alert and had no neu-rological deficits.
