内頸動脈の走行異常は今日まで散発的に報告がなされているが, それらの症例の主訴は咽喉頭の異常感が殆どである.実際, 筆者らも2年前に咽喉頭異常感を主訴とする内頸動脈の走行異常症例を経験した.その際, 内頸動脈の走行異常が本当に異常感の原因と成りうるものか疑問に思った.そこで, 主訴の如何にかかわらず我々はこの2年間に診察し得た患者の中に内頸動脈の走行異常を有する症例の発見に務めてみた.その結果, 内頸動脈の走行異常を有する症例は決して稀なものではないことが解った.2年間で28例発見でき, 男性9例, 女性19例, 女性に多くみられた.右側20例, 左側3例, 両側8例, 右側に多くみられた.最も多い主訴は耳鳴, 難聴などの耳性疾患が10例で咽喉頭異常感は3例しかみられなかった.内頸動脈内側偏位は咽喉頭異常感の原因に成りえないと考えられる.

Some reports have been made about tortuosity of the internal carotid artery, and it has been said that most of the chief complaints were abnormal sensations in the throat.<BR>Because we had questions about these complaints, we tried to find cases of tortuosity of the internal carotid artery.<BR>As a result, we found 28 cases during the past two years. Nine were male, and 19 female, this complaint was thus found more frequently in females. Twenty cases were on the right side, 3 cases were on the left side, and 5 cases were on both sides. This revealed that it was definitely more frequent on the right side.<BR>The most common chief complaints were about aural disturbance, on the other hand, abnormal sensation in the throat was found in only three cases. We have concluded that tortuosity of the internal carotid artery does not cause abnormal sensation in the throat.
