Role of hepatic Doppler as compared to Fibro-scan in evaluation of post virus C hepatic fibrosis

Abstract

Abstract Background Chronic infection with hepatitis C virus (HCV) is a disease of global importance with a large burden of morbidity and mortality. hepatitis c virus can cause progressive liver damage which may result in liver cirrhosis and hepato-cellular carcinoma . Aim of the work The aim of our study was to examine the efficacy of hepatic Doppler indices, namely hepatic vein wave form, hepatic vein maximum velocity ,hepatic artery RI and portal vein maximum velocity and portal vein wave form for evaluating the degree of hepatic fibrosis in chronic hepatitis C (CHC) patients as compared to transient elastography. Patients and methods our study was done over period from September 2018 till April 2019 included 40 patients from eldemerdash hospital designed to include all hepatitis c positive patients with any age or sex excluding other cause of liver cirrhosis (negative hepatitis B, negative auto immune hepatitis) in absence of obesity or ascites. hepatic vein maximum velocity, hepatic artery RI, portal vein maximum velocity, TE were performed to all patients. fibrosis was assessed on semi quantitative scoring system (METAVIR score ). we examine the efficacy of each of Doppler indices in differentiating different stages of hepatic fibrosis and their diagnostic accuracy in predicting significant fibrosis and cirrhosis . Results on comparing the fibrosis &non fibrosis groups by TE according to Doppler measurement we found statistically significant higher means of the portal vein maximum velocity (PVmax) for the non fibrosis group as compared to the fibrosis group (24.15±9.71 and 15.94±3.35 respectively with p value<0.001) also found significantly lower HAPSV/PVmax ratio for the non fibrosis as compared to fibrosis group (1.58±0.41 and 2.59±1.17 respectively with p value 0.011) finally, we found that there was significant change of the HV waveform pattern for the non fibrosis (normal triphasic ) as compared to fibrosis (monophasic or biphasic ) (x2=4.353 with p value 0.038)
