The article reports data of time average maximum velocity, time average velocity, peak systolic velocity, and diastolic velocity in general, internal and external carotids in patients suffering from arterial hypertension during coloured full-duplex scanning of carotids. It was established that in patients suffering from arterial hypertension the multidirectional changes of indexes of linear blood stream take place. The changes were different, with decreasing of blood stream in internal carotids and increasing — in external and general carotids. The presence of asymmetry of blood stream was also revealed in carotids.
