title: Kinking of a Warren shunt as a cause of recurrent variceal hemorrhage.
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.
