Meso-Rex shunt using deep femoral vein conduit: first report

The Meso-Rex shunt (MRS) procedure was first described in 1992 by de VILLE et al. for the treatment of extrahepatic portal vein obstruction (EHPVO) in paediatric liver transplant patients. This technique provides more physiological relief of portal hypertension compared to the porto-systemic shunts, which can lead to long-term complications such as hyperammonaemia and hepato-pulmonary syndrome. Different conduits as autologous and cryopreserved veins or prosthetic grafts have been previously reported. We present herein the first case of a MRS using the autologous deep femoral vein in a 17-year-old female patient affected by EHPVO from unknown reasons.
