[Radionuclide assessment of microcirculatory disorders in varicose disease of the lower extremities].

Comprehensive assessment of macro- and microhemodynamics of the lower limbs in 61 patients with varicosis using radionuclide angiography and the method of 99m-Tc-pertechnetate clearance from the intracutaneous depot has shown that peripheral circulatory disturbances correspond to a stage of disease and trophic skin lesions depend on the state of microcirculation. Two types of microcirculatory disturbances have been revealed using a detailed analysis of indices of the blood circulation at the stage of decompensation: I--marked retardation of the capillary blood flow; II--the presence of arteriolovenular shunting. Radionuclide methods make it possible to unravel some problems related to the pathogenesis of disease and to obtain additional diagnostic information on radiopaque and ultrasonic investigations.
