An increase in arterial inflow at the jejunum was noted in a patient with esophageal varices who had received total gastrectomy and esophagojejunostomy. There was an peculiar angiographic sign in the portal circulation to this situation; namely, the jejunal vein had a divide between the hepatofugal and hepatopetal flow. The divide, termed a "watershed", was obtained at first, and thereafter esophageal varices were identified. Because a hyperdynamic state in the splanchnic circulation contributes to the formation of esophageal varices, the enhanced jejunal circulation may participate in the development of the varices, and a special angiographic sign -a "watershed"- may be a sign of a splanchnic hyperdynamic state.
