Role of Colour Doppler in Evaluation of Hemodynamic Changes in Chronic Hepatitis C Infection

Abstract

Purpose of the Study: The estimation of the degree of hepatic fibrosis is important for diagnostic and therapeutic management of patients with chronic liver disease, in particular those associated with hepatic viral infections. In cirrhosis portal blood inflow, hepatic resistance and portal venous pressure increase. Doppler sonography is non-invasive diagnostic modality based on hemodynamic parameters. Hemodynamic changes might have developed even in cases with normal findings on B mode sonography. Therefore, assessment of these alterations has importance for early diagnosis and for close follow-up of previously dia-

Doppler ultrasound in liver cirrhosis: correlation of hepatic artery and portal vein measurements with model for end-stage liver disease score in Egypt

“…1b, 3, and 4). We had found that PVV did not significantly correlate with MELD score; this was concordant with many works of literature [16][17][18][19] who had documented the same issue; however, this was contradicting the Berzigotti et al study, where they reported a low flow velocity of < 20 cm/s in addition to a caliber increase in the main portal vein (MPV) were considered diagnostic features of portal hypertension [20]. However, we did not measure the portal vein diameter, and the possible reason for the contradicting data in the PVV was the heterogeneity of the cirrhotic patients included in various studies, also the type of hemodynamic disturbances, for example, the presence of hyperkinetic syndrome or portosystemic collaterals.…”
