    Sinusoidal Obstruction Syndrome (SOS/VOD) is a severe post-transplant complication in children, with incidence rates exceeding 15%.

  • 2

    Anicteric SOS/VOD occurs in up to 30% of pediatric patients, complicating diagnosis due to the lack of hyperbilirubinemia.

  • 3

    The European Society for Blood and Marrow Transplantation established pediatric-specific diagnostic criteria to improve SOS/VOD detection.

  • 4

    Defibrotide has shown promise in reducing endothelial damage and improving outcomes in pediatric patients at risk for SOS/VOD.

  • 5

    Diagnostic criteria significantly influence the reported incidence and severity of SOS/VOD, with the pEBMT criteria being more sensitive than previous standards.
