Abstract:
The terminology of juxta-dural ring aneurysms of the internal carotid artery is reviewed historically with special reference to those aneurysms protruding ventrally. The first description of such cases was made by Drake as exceptional examples of carotid-opthalmic aneurysms. Yasargil and Fox termed them ventral (inferior) internal carotid artery aneurysms. The term (ventral) paraclinoid aneurysms was coined by Nutik. We introduce the concept of carotid cave aneurysms. The name superior hypophyseal artery aneurysms was proposed by Day. Other related terminologies by various authors are also described.
