一側椎骨動脈閉塞およびメニエル症候を伴つた頸部異物例—長期観察例

A CERVICAL FOREIGN BODY THAT CAUSED A COMPLETE OBSTRUCTION OF THE VERTIBRAL ARTERY A COMPANIED BY MÉNIÈRE'S SYNDROME

　I．緒言

　頸部の深部受容器と眼球運動や姿勢反射，さらに，自律神経系との関連性が臨床的にも，実験的にも証明されている。今回，戦傷後，30年近くも頸部異物のためにより，メニエル病様症状および頭痛に苦しんで生活していた症例で，異物摘出後は，症状の軽快を認め，社会復帰した1例を経験し，頸性めまいの発症機序の解明の1つとして追加報告する。

　A case of foreign body (a fragment of a cannon ball) and thorotrastoma of the neck with a complete obstruction of the right vertebral artery is reported. The patient complained of vertigo, oscillopsia, headache, tinnitus, slight deafness, signs of autonomic nerve disturbances, partial glossopharyngeal paralysis and paresthesia of the right extremity.

　The fragment was surgically removed and the obstruction of the right vertebral artery was ascertained. The patient's symptoms dissappeared after the operation which suggests that the case was affected by cervical syndrome (Barre-Lieou syndrome) due to the irritation of the fragment causing disturbances of the propioceptive receptor of the deep cervical muscles and the cervical sympathetic nerves. We believe that this case must be followed for a long period time, especially concerning the lookout for malignant trans-formation due to the radioactivity of the thorotrast.
