Gallbladder varices in a pediatric patient after roux-en-Y gastric bypass.

This is a case with associated radiologic images for a pediatric patient who developed portomesenteric and splenic vein thrombosis (PMSVT) after Roux-en-Y gastric bypass with subsequent development of portal cavernoma and gallbladder varices (GBV). This case highlights both the importance of post-operative prophylactic anti-coagulation after gastric bypass and detailed imaging following a diagnosis of PMSVT. This case is relevant for pediatric surgeons as they are performing this operation more frequently with the increase in pediatric obesity.
