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.
鉴于糖尿病血管退行性变的早期预防，其早期诊断是当今的一个问题。对89例胰岛素依赖型糖尿病患者，采用阻抗法通过临床疾病分期指标研究了腿部外周血管段和脑动脉系统的变化。发现了表征血管壁结构张力变化的阻抗指标变化，以及作为脑血流动力学基本参数的容积半球循环速度变化。与外周血管段不同，颈动脉系统的复阻抗指标变化出现在中度严重的糖尿病形式中。阻抗无创检查可为腿部外周血管段和由疾病临床分期决定的脑血管系统提供早期临床前信息数据。
