The waiting lists for organ transplants are growing faster than the organs available.
Cadaveric - or dead - donors account for the bulk of transplants because they can donate several organs apiece whereas living donors give a single kidney or a piece of their liver. In the USA, there was a total of 5,984 dead donors in 2000, an increase of 2.7 percent over 1999, continuing the slow rise of recent years. The number of living organ donors climbed by more than 16.5 percent in 2000, the highest single annual rise, with more than 5,500 people giving away an organ.
"Living" liver donation is possible because of the liver's ability to regenerate. Within a month or so of a transplant both recipient and donor should have healthy, full-sized livers. The procedure has been widely available only since 1999. By the start of 2001, about 500 people around the world had donated liver sections to other adults. The risk of death to the donor is about 1 in 150. By comparison, the risk of death for those who donate a kidney, a long-standing practice, is only 1 in 10,000. At least two deaths, maybe three, have occurred so far - one in the USA and one or two in Europe.
