[Complex radionuclide evaluation of the hemodynamic state in varicose veins of the lower extremities].
The main parameters of central hemodynamics and regional blood volumes were determined in 106 patients with lower limb varicosity by computer radiocardiography and radiometry of the lower limbs in horizontal and vertical positions of the body. It was found that the clinical stages of compensation and decompensation are paralleled by definite combinations of changes in the circulation volume, minute and stroke values of the cardiac output and regional blood volumes in the lower limbs. Comprehensive appraisal of circulation enabled the authors to distinguish a "transient" stage of the disease according to the character of changes in the main hemodynamic values. It is very difficult to determine this stage from the clinical signs. The study showed that the transition from the stage of compensation to that of decompensation in varicose disease is due to the time factor which is within the limits of up to ten years from the onset of the disease in most cases.
