Cases studies of tortuosity of the internal carotid artery

Abstract

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.
Because we had questions about these complaints, we tried to find cases of tortuosity of the internal carotid artery.
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.
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.
