Influence of Liver Fibrosis on Hepatic Artery Doppler Resistance Index in Chronic Hepatitis of Viral Origin

Abstract

Background: Hepatic arterial Doppler sonography is increasingly being used in liver diagnostics. The determinants of the elevation of hepatic artery impedance indexes in chronic liver disease, however, have still not been fully clarified. The aim of the present study was to investigate the relationship between histological alterations and liver circulation in chronic hepatitis. Methods: Hepatic artery resistance index and portal flow velocity were measured using Doppler sonography in 47 patients with chronic hepatitis of viral origin diagnosed at histopathology. The patients were divided into two groups, those with mild and those with severe alterations, in accordance with the various histological parameters of the Knodell scoring system. Results:

• Chronic Hepatitis Doppler Sonography Liver Fibrosis Portal Velocity Resistance Index
