Correlation of hepatic venous pressure gradient with variceal bleeding, size of esophageal varices, etiology, ascites and degree of liver dysfunction in cirrhosis of liver.

ABSTRACT

An elevated hepatic venous pressure gradient (HVPG) has been associated with risk of variceal bleeding, and outcome and survival after variceal bleeding. In this pilot study, we measured HVPG in 40 patients with liver cirrhosis and studied its relationship with etiology of liver disease, esophageal variceal size, history of variceal bleeding or ascites, biochemical liver tests and Child-Pugh class. There was no procedurerelated complication. The mean (SD) HVPG was similar in patients who had history of variceal bleeding as compared to those who did not (15.4 [2.8] mmHg vs. 13.9 [2.7] mmHg, p=0.1); HVPG had no significant association with etiology of cirrhosis (p=0.4). HVPG levels were significantly higher in patients with larger esophageal varices (grade III/IV vs. I/II 15.2 [2.7] mmHg vs.13.1 [2.8] mmHg, p=0.04), poorer Child- Pugh class (B or C versus A), and presence of ascites (p=0.04). Thus, HVPG correlated with variceal size, Child-Pugh class, and presence of ascites, but not with variceal bleeding status.
