Liver transplantation can be divided into living parental liver transplantation and brain-dead or heart-dead liver transplantation, whether it is living liver transplantation or brain-dead liver transplantation, for the recipient, the entire liver is removed and then replaced with a new liver. This is not a whole liver transplant for the donor, but for the recipient it is still a whole liver transplant. In addition, in the case of brain death or cardiac death, the donor can be divided into partial or whole liver transplantation. Partial transplantation is called split transplantation, where a liver is divided into two parts and given to two recipients, which is not a whole liver transplant from a certain point of view, but is a partial liver transplant, but for the recipient, it is a whole liver transplant regardless of the transplantation method.
