PORTAL BLOOD VELOCITY AND PORTAL BLOOD-FLOW IN PATIENTS WITH CHRONIC VIRAL-HEPATITIS - RELATION TO HISTOLOGICAL LIVER FIBROSIS

Background/Aims: This study represents an. attempt to correlate portal hemodynamics in patients with chronic hepatitis. Materials and Method s: Portal blood velocity and portal blood flow were determined using t he duplex Doppler system in 47 patients with chronic viral hepatitis, and findings were compared with the hepatic histological features. Res ults: Portal blood velocity decreased with the progress of chronic hep atitis, and closely correlated with the histological degree of liver f ibrosis (p<0.0001). The portal blood velocity in patients who had seve re bridging fibrosis was significantly lower than that in the patients who had mild bridging fibrosis. However, the portal blood flow in, pa tients with chronic persistent hepatitis and chronic active hepatitis was comparable with that in the controls, and did not correlated with liver histological findings. Conclusions: These findings suggest that the portal blood velocity is a more sensitive indicator for assessing portal hemodynamics than portal blood flow in chronic viral hepatitis, and may be a useful test for differentiating chronic hepatitis with s evere fibrosis from chronic hepatitis with mild fibrosis.
