[Ethical and social problems posed by organ transplantation].

Organ transplantation more than a scientific fact is now a social fact. Since the first organ transplantations in France, forty years ago, medicine demonstrated its ability to perform the operation and to obtain (what was more difficult) the tolerance of the graft but medicine so far remains unable to give the material: organs. These organs are given by the donor's relatives when the kidney is concerned and when it is a donation from a living person. But such donation remain strictly limited in our country (less than 5 p. cent of the kidney transplantations) due to the risk of moral pressure and commercialization. More often and for the other organs (liver, heart, lung) the donation is obtained after death, a special and dramatic death: the brain death. The nowadays spectacular results of organ transplantation 70 to 80 p. cent survival rate at 10 years with a complete rehabilitation gave a considerable increase on the demand. Unfortunately organ transplantation is the victim of its success, the number of donor's organ being insufficient to satisfy the needs. So in December 1990, 6,055 patients were on the waiting list and only 3,772 (56 p. cent) were transplanted. In December 1991, 6,334 patients were on the waiting list and may be only 4,000 could be transplanted. So the difference between the needs and the possibilities is increasing each year with for consequences, the death of 10 p. cent of the waiting patients and, for those who could be transplanted, a considerable increase in the waiting period responsible for slow deterioration of their status and less chances of success.(ABSTRACT TRUNCATED AT 250 WORDS)
