For those who may not have been paying attention to the medical news lately, reports from various reputable sources have found that Italian surgeon Dr. Sergio Canavero plans to conduct the world’s first human head transplant within the next two years. He actually has his patient set and ready to go. The donor body has yet to be identified.
Canavero first proposed the idea two years ago as a means of extending people’s lives whose bodies have been riddled with illnesses, cancers, or other incurable medical disorders. The first patient willing to have his head transplanted onto a new body is Valery Spiridonov, a 30-year-old Russian who suffers from Werdnig-Hoffman disease, a genetic disorder that causes his muscles to deteriorate. A donor body will be attached to Spiridonov’s head through spinal cord fusion, a process that has had some success in animals.
The first successful animal head transplant took place in 1970 where the head of a monkey was transplanted onto the body of another primate. The monkey lived for nine days before the body rejected the new organ. However, in the 1970s, there were few processes and medications that helped to keep transplanted organs from being rejected. Since then, the invention of drugs that assist with the acceptance of transplants, such as with lungs and hearts, can reduce the risk of rejection significantly.
For a head to be transplanted onto a new body, the spinal cord of the donor body will have to be fused onto the spinal cord of the recipient’s head. The process was described in a recent issue of the journal Surgical Neurology International.
What are the consequences for society if we are able to successfully transplant heads? Are we moving closer to the Frankenstein movies of the past or the upcoming science-fiction movies that haven’t yet been created?
Looking at the progression of organ transplantation, the field has brought forth tremendous challenges, the biggest one being a shortage of organs. As most people are aware, there is an organ transplant waiting list for various operations: liver, kidney, lung, eyes, heart and so on. Then, another big concern is the issue of organ trafficking and transplant tourism. In some cases, organ donation was no longer a voluntary notion but one of coercion and profit-making. That brought up the issue of organ trafficking. In Germany in 2012, a significant number of patient records were tampered with to increase the number of organs that could be used for transplants. In other words, people were donating organs that they had no intentions of giving up.
Earlier, organ trafficking involved the forced removal of organs from people, mainly those in prison who were to be executed. The practice was very common in China. It wasn’t until 2001 when the public became aware of the unethical removal of executed prisoners’ bodies. Chinese authorities claim that the organ harvesting took place after the execution with permission, but these official statements are still questioned today. It was later discovered that some Chinese hospitals were actually taking organs from living people without permission and under torturous conditions.
What about head transplants? Could this possibly happen to someone’s head? When a donor (with or without consent) provides a kidney, lung or part of a liver, that person can still live and breathe. When a head is removed from a person’s body, death is eminent. The ethical nature of head transplantation could become a huge human rights concern if we aren’t careful in how we handle it.
The ethics of the head transplantation project that will likely take place a few short years from now must be investigated now before human head trafficking occurs much like other organ harvests of the past. Bioethical committees in many countries are now looking into the potential concerns that will likely follow a successful head transplant.
