Core Tip
Core tip: Hepatic venous outflow obstruction (HVOO) is a rare and severe complication following pediatric liver transplantation that leads to graft loss in the majority of patients. However, it remains controversial whether stent placement or balloon angioplasty is required for patients with HVOO. This study reported our experiences with using balloon dilatation as part of the treatment for HVOO in five children subjected to pediatric liver transplantation, providing valuable information for the successful treatment of such patients. Balloon dilatation is an effective and safe treatment for HVOO in pediatric patients following liver transplantation, and re-venoplasty is recommended even for patients with recurrent HVOO.
