Twenty-two autopsy cases with portal hypertension were studied. Micropac added with gelatin was injected into blood vessels and the structure of blood vessels in the esophagus was observed.1. From the esophago-gastric junction, small vessels of 2-3cm in length, running in the "bamboo-blind like" pattern, were observed with little anastomosis or weaving.2. Most of the vessels in the submucosa and lamina propria were observed running axially, and three to four vessels in the submucosa were weaving and dilated.3. At the transitional area among above two vascular structure, specific pattern was observed. It was distinguished 15 of 22 cases on softex photographs with about 1cm length. The largest varicose was seen in this area.4. The mucosal protuberance observed at endoscopy consisted of blood vessel running in the submucosa as a "trunk" with many branching smaller vessels arising from its "trunk".
