The European Society for Blood and Marrow Transplantation (EBMT) has recently announced new diagnostic criteria for pediatric hepatic veno-occlusive disease (HVOD) after hematopoietic stem cell transplantation (HSCT). We retrospectively inspected 97 ultrasound exams of 60 pediatric HSCT patients, and compared its diagnostic value using the Baltimore, Seattle and pediatric EBMT criteria. Nine of the ten patients who were diagnosed as HVOD only in the EBMT criteria had severe or very severe HVOD. In the Seattle and EBMT criteria, portal vein velocity, peak systolic velocity and resistance index of hepatic artery, gallbladder wall thickening and ascites were statistically significant. No ultrasound variable showed significant association in the Baltimore criteria. All patients with portal vein velocity below 10 cm/s were in higher EBMT grade. A scoring system was developed, to evaluate the overall relationship of the ultrasound findings with the diagnosis of HVOD, showing fair (0.768 and 0.733) AUC in the ROC curve of EBMT and Seattle criteria.
