The system approach in the estimation of arterio-venous correlation under hypertensive encephalopathy

Abstract

System approach was used to determine arterio-venous correlation under hypertensive encephalopathy (HE). 250 patients with HE I—III and 30 controls matched for age and sex were examined. The clinical, ultrasonic diagnostics and quality of life (QL) index were applied. By means of ultrasonic diagnostics it was shown that in the process of HE development and progression the changes on all structural functional levels of cerebral vascular system occur. The QL analysis depending on the HE stage shown that as the disease progresses the physical constituent of health increases and the mental constituent of health decreases. In the group of patients with venous discirculation of the blood pain barrier was decreased, physical and mental health constituent were lowed.
