Core Tip

Core Tip: Tailored graft reduction techniques—hyper-reduced, reduced, and monosegmental—effectively address graft size mismatch in pediatric liver transplantation. Optimal outcomes depend on careful donor selection, graft thickness adjustment, and individualized surgical planning. Vigilant attention to graft-to-recipient weight ratio and vascular anatomy minimizes complications. Long-term data confirm these techniques are safe, durable solutions for small pediatric recipients.
