title: [Impedance methods of studying the vascular changes in insulin-dependent diabetes mellitus].
abstract: The early diagnosis of the vascular degenerative changes in diabetes mellitus is a present day problem in view of their early prophylaxis. In 89 patients with insulin-dependent diabetes the changes of the peripheral vascular segments in the legs and of the brain arterial system were studied with impedance methods by clinical index--stage of the disease. Changes of the impedance indices which characterize the structural-tonic changes of the vascular wall as well as changes of the velocities of the volumetric hemispheric circulations--the basic parameters of brain hemodynamics--were found. In difference from the peripheral vascular segments, the changes of the complex impedance indices of the carotid arterial system occur in the moderately severe forms of diabetes mellitus. The impedance noninvasive examinations give early preclinical informative data for the peripheral vascular segments of the legs and for the brain vascular systems determined by the clinical stage of the disease.
