[Clinically significant anomalies of the carotid arteries].

During 2002-2010 years the authors made more than 14 thousand USDS of the brachycephalic zone arteries. In 32 cases (32 men and 8 women) there were disturbances of blood flow due to local intima dysplasia (hyperplasia) in the zone of bifurcation of the common carotid artery by the detected "pathological valve". Alterations in the bifurcation of the common carotid artery were confirmed by angiographic investigation.
