  • Title: Pre- and postoperative imaging of the Rex shunt in children: what radiologists should know.
    Author: Cárdenas AM, Epelman M, Darge K, Rand EB, Anupindi SA.
    Journal: AJR Am J Roentgenol; 2012 May; 198(5):1032-7. PubMed ID: 22528892.
    Abstract:
    OBJECTIVE: The objective of this article is to illustrate the imaging features of patients with extrahepatic portal venous obstruction who are evaluated before or after a Rex shunt surgery. CONCLUSION: The Rex shunt is a potentially curative surgical procedure that reestablishes physiologic hepatopetal portal flow. It is typically accomplished by interposing a vascular conduit between the superior mesenteric vein to the still patent intrahepatic portal venous system. This procedure results in resolution of portal hypertension.
