Core Tip	Hepatic venous outflow obstruction (HVOO) is a serious complication of liver transplantation, particularly with the piggyback technique where the inferior vena cava is preserved. A unique approach using a retrohepatically placed tissue expander may successfully relieve IVC compression caused by graft malposition and stabilize the patient's hemodynamics without needing major surgery. This minimally invasive method demonstrates adjustable and effective decompression of the hepatic veins, suggesting a new therapeutic option for complex vascular complications after liver transplant. Our report highlights the importance of proactive monitoring and individualized interventions in managing HVOO to improve graft function and patient outcomes.
