Complications are infrequent, but when they occur, they are severe and may be fatal. Continue reading
Hepatic sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) is a life-threatening complication of hematopoietic cell transplantation (HCT) that belongs to a group of diseases increasingly identified as transplant-related, systemic endothelial diseases.
