Liver donation taken from a brain dead person is known as a Cadaveric donation. It is done only if the family of the deceased readily donates the organs of the person before discontinuing life support. This can be done by persons who have suffered brain injury after a fatal accident, or after a fatal brain hemorrhage and the person in the hospital survived by life support systems. But the liver should not have been damaged in such accidents. After liver retrieval from the donor the liver is preserved in special preservation solutions. It can be preserved like this for 12-15 hours. The liver transplants are strictly done only if the blood group is matching. And allocation of such organs is strictly on the urgency of the requirement and the waiting list of patients.
Apart from getting a liver donation from a brain dead person, a donation is also possible from a living person who is ready to donate half of his/her liver. Preferably the donor should be a relative of the patient. The liver donation operations are very safe as also the half liver regenerates quickly in both the donor and the recipient in not more than a few weeks. Even though the half liver can also perform all liver functions properly because of the immense reserves available in the liver.
After the liver donation surgery takes place, the donor needs to stay in the hospital for about 5-10 days for healing, and thereafter a rest of 3-4 weeks is required for proper recuperation. Post this period the donor can resume the normal activities but should avoid strenuous physical exercise. Heavy exercising and weight lifting and other such activities can be undertaken after 3 months of the surgery.
There are no restrictions in the diet, as the liver functions normally even if half of it has been donated. There is no decrease in the longevity of life nor does the surgery have any other long-term consequences.
