Abstract：Objective: To study the mechanisms of portal hypertensive gastropathy. Methods: With blood gas analysis to determine the blood gas changes of right gastroepiploic arteriovenous parietal branches and the pressure on right gastroepiploic veinin 43 eases of portal hypertension. Results: ① PO2 of femoral artery in those with portal hypertension was lower than in controlgroup. ② PO2 of right gastroepiploic arteriovenous parietal branches in those with portal hypertension was lower than in controlgroup. Pressure on right gastroepiploic venous branch was higher than that in the control group. PH and HCO3- of parietal yenous branch were lower than in control group and cubital vein in the same group. The changes above were more obvious in thepatients complicated with portal hypertensive gastropathy. Conclusion: The opening of gastric submucosal arteriovenous shuntby increased portal pressure causing gastric mucosa ischemia or hypoxia and local gastroparietal acidosis is one of the mechanisms of portal hypertensive gastropathy.
