a person dying who donates a liver to a dying person
It is possible to transplant part of a liver from a living donor and have both donor and recipient survive.
The donor liver is placed in a different site, but it still has to have the same connections.
Two sections of a donor liver have been enough to save a patient in liver failure, especially if the patient is a child.
It is highly unlikely the transplant team will risk the donation. Both the recipient and the donor could be at risk. Methadone does affect bone marrow both by its use and because of why it is being used. High risk behavior including using injectable drugs and unsafe sexual practices while high leaves the possible donor suspect for HIV and other diseases. While offering bone marrow is a noble gesture, the risk to the patient is high.
Replacement of a whole diseased liver by a healthy donor liver.
Depends on if it's a live donor or a dead donor. With a live donor only part of the liver is harvested for transplantation, and the remaining part will grow back to (close to) its original size within weeks.
He will go on a waiting list for a cadaver donor liver. He will get the transplant and live for his expected life-span. If no cadaver liver donor is available, they will treat him symptomatically and try to find a living donor among relatives who are compatible. If none is found, his long-term prognosis is not good. Half a liver from a living donor will regenerate and both the donor and the recipient will have an entire liver after a few months.
Orthotopic transplantation is the replacement of a whole diseased liver with a healthy donor liver.
Liver transplantation is a surgery that removes a diseased liver and replace it with a healthy donor liver.
There is a high risk of tumor recurrence and metastases after transplantation.
When an orthotopic transplantation is performed, a segment of the inferior vena cava attached to the liver is taken from the donor as well.
Reduced-size liver transplantation is the replacement of a whole diseased liver with a portion of a healthy donor liver.
