Introduction
Portal vein thrombosis (PVT), a common complication of end stage liver disease, is no longer considered a definite contraindication for liver transplantation (Paskonis M et al. Clin Transplant 2006; 20: 551–562). Creation of a renoportal anastomosis is a surgical strategy to secure portal flow to the liver graft in case of extensive PVT (Paskonis M et al. Clin Transplant 2006; 20: 551–562). We report a patient with PVT requiring liver transplantation with renoportal anastomosis. After transplantation, the patient developed severe bleeding from esophageal varices despite patency of the renoportal anastomosis. Secondary surgery, including esophagogastric devascularization for the prevention of further bleeding was discussed. 4D flow MRI, however, revealed orthograde flow not only in the renoportal shunt but also in esophageal varices, suggesting low risk for recurrent variceal bleeding, thereby averting secondary surgery.
