Abstract

In order to clarify the angioarchitecture of the palisade zone in the lower esophagus for portal hypertensive cases, we examined the thirty untreated autopsy cases of portal hypertension. At autopsy, barium added gelatin was injected from gastric cornary vein of the gastric wall and we observed them histologically and histometrically.
1) In portal hypertension, the palisade zone has increasing veins running in the submucosa, which veins belonged originally to the lamina propria.
2) A difference in angioarchitecture is present between the palisade and truncal zones.
3) The palisade zone in esophageal varices was classified into two types of angioarchitecture by Hashizume. Our 30 cases were composed of 22 cases with palisading type and of 8 those with bar type. The later showed well developed varises than the formar.
