A case of Takayasu's disease with ruptured carotid aneurysm.

Recently, a number of cases of Takayasu's disease having dilatative or aneurysmal lesions have been reported. Such lesions have come to be considered important manifestations of Takayasu's disease. A case, whose right common carotid artery perforated spontaneously and became a pseudoaneurysm, without any other stenotic lesion is presented with a review of the literature. Surgical treatment was performed successfully.
