Special features of venous hepatic blood flow with the ischemic disease of heart and the diffuse diseases of the liver

Abstract

According to the data of literary sources and the results of its own studies is carried out the analysis of hepatic blood flow in the standard, with ishemic heart disease and diffuse liver diseases of noninfectious etiology. Hepatic hemodynamics within the standard has a number of the special features: basic blood flow is achieved on the veins, hepatic artery plays subordinate role. Blood flow in the hepatic veins depends on the propulsive activity of heart (right cameras) and has the phase structure of Doppler spectrum. With nonalcoholic fatty disease of the liver in combination with portal hypertension occur the expansion of hepatic artery and gate vein with an increase in the velocity parameters of the blood stream, the contraction of hepatic veins with the depletion of Doppler spectrum. The pathognomonic signs of venous stagnation and disturbance of intra-hepatic hemodynamics with the severe and chronic forms of ishemic heart disease are the expansion of diameter and reduction in the speed of blood flow in the gate and hepatic veins. The general components of the pathogenesis of the nonalcoholic fatty liver and ishemic heart disease in the practical activity require knowledge and estimation of the state of hepatic blood flow for determining of further tactics and forecast of both diseases.
