Hematopoietic stem cell
Hematopoietic stem cell transplantation (HSCT) is a procedure performed in some people to treat certain blood or bone marrow cancers. Immediately before an HSCT procedure, a patient receives chemotherapy. Hepatic VOD can occur in people who receive chemotherapy and HSCT. Hepatic VOD is a condition in which some of the veins in the liver become blocked, causing swelling and a decrease in blood flow inside the liver, which may lead to liver damage. In the most severe form of hepatic VOD, the patient may also develop failure of the kidneys and lungs. Fewer than two percent of people develop severe hepatic VOD after HSCT, but as many as 80 percent of people who develop severe hepatic VOD do not survive.
