Background: The categorization of intrahepatic portal venous system (IHPS) patterns using wedged hepatic venous portography (WHVP) has proven to be an effective tool in the preoperative evaluation of Rex recessus and in identifying pediatric patients with extrahepatic portal vein obstruction (EHPVO) who are suitable for meso-Rex bypass (MRB). Despite this classification system being proposed a decade ago, its clinical application remains underutilized.
Methods: A single-center retrospective study of 182 children with EHPVO was conducted between October 2014 and July 2023 when MRB was attempted.

Portal interventions in pediatric patients present unique difficulties when compared to adult procedures. In addition, children who need a portal intervention require a different workup and clinical management. Based on these elements, the clinical decisions for the study and treatment of these pathologies are different.

Background: Meso-Rex bypass is the surgical intervention of choice for children with extrahepatic portal vein obstruction (EHPVO). Patency of Rex vein, umbilical recessus of the portal vein, is a prerequisite for this surgery. Conventional diagnostic modalities poorly detect patency, while transjugular wedged hepatic vein portography (WHVP) accurately detects patency in 90%.

A 53-year-old female with primary biliary cholangitis was referred for the evaluation of a hepatic nodule identified during routine imaging. Ultrasonography revealed a homogeneous, hypoechoic, 18 mm nodule in segment 3 of the liver. On dynamic CT and MRI, the nodule showed mild enhancement at the hepatic artery-dominant phase.
