Endovascular management of acute portal vein thrombosis in pediatric liver transplant recipients less than 20 kg.

Background: Pediatric recipients of orthotopic liver transplants are at risk for post-transplant complications, particularly acute portal vein thrombosis, which jeopardizes patient survival and graft function. The incidence and impact of portal vein thrombosis are more severe in children compared to adults, with those under 5 most vulnerable to thrombotic events.

Objective: This study aims to report our institutional experience with endovascular interventions for treating portal vein thrombosis in 11 pediatric liver transplant recipients who presented within 30-days post-transplant.
