title: [Changes in the vessel wall in the region of the carotid syphon (author's transl].
abstract: The present paper reviews changes in the vessel wall in the carotid syphon, including variations in calibre, stenoses, post-stenotic dilatation and aneurysms. Particular attention is paid to a supraclinoid circular stenosis, which corresponds in its localisation to the emergence of the internal carotid artery from the dura. Reference is made to new anatomical findings in this region. The haemodynamic basis of poststenotic dilatations and the development of acquired aneurysms as a result of this mechanism are discussed. Examples of post-stenotic aneurysms are demonstrated.
