[Morphological features of atherosclerotic plaques of internal carotid artery sinus (biopsy data from carotid endarterectomy)].
A histological study was made of 140 atherosclerotic plaques in the sinus of the internal carotid artery (ICA) removed at carotid endarterectomy. New formed thin-walled vessels of various diameter having the structure of arteries, blocking arteries and, presumably, arteriolo-venous anastomoses were found in 112 plaques. The majority of the vessels were oriented along the ICA this indicating blood circulation parallel to that in ICA. It is assumed that deficiency of blocking arteries results in the development of intraplaque hemorrhages from thin-walled vessels.
