Introduction: Hepatic veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is a complication that is typically associated with conditioning for hematopoietic stem cell transplantation (HSCT). In patients with concomitant multi-organ dysfunction, mortality may be >80%. Recently, the European Society for Blood and Marrow Transplantation established separate criteria for diagnosis and severity of VOD/SOS for adults and children, to better reflect current understanding of the disease. Areas covered: This review provides an overview of post-HSCT hepatic VOD/SOS and defibrotide, including its pharmacological, clinical, and regulatory profile. In children and adults following HSCT, defibrotide is approved for the treatment of hepatic VOD/SOS with concomitant renal or pulmonary dysfunction in the United States and for the treatment of severe hepatic VOD/SOS in the European Union. Day +100 survival rates with defibrotide are superior to those of historical controls receiving best supportive care only, and safety profiles are similar. Expert commentary: Defibrotide appears to act through multiple mechanisms to restore thrombofibrinolytic balance and protect endothelial cells, and there are promising data on the use of defibrotide for VOD/SOS prophylaxis in high-risk children undergoing HSCT. An ongoing randomized controlled trial in children and adults will better assess the clinical value of defibrotide as a preventive medication.
