Abstract
Upper gastrointestinal hemorrhage after portal decompression requires appropriate endoscopic and radiologic evaluation for unrelated causes. Splenoportography may be more definitive than selective visceral angiography and in the present case showed a patent but kinked venovenous anastomosis with a high splenic pulp pressure. A mesocaval interposition shunt controlled the hemorrhage. Various technical factors responsible for anastomotic narrowing and kinking of the Warren shunt are briefly mentioned.
