Head Transplant Sergio Canavero

First transplant ‘possible in two years’

25 Feb, 2015

Canavero says the first full-body transplant could take place within two years. He plans to announce the project at the annual conference of the American Academy of Neurological and Orthopaedic Surgeons (AANOS) in Annapolis, Maryland, in June.

The procedure involves cooling the recipient’s head and the donor body to extend the time their cells can survive without oxygen. The tissue around the neck is dissected and the major blood vessels are linked using tiny tubes, before the spinal cords of each person are cut. The recipient’s head is then moved onto the donor body and the two ends of the spinal cord – which resemble two densely packed bundles of spaghetti – are fused together. To achieve this, Canavero intends to flush the area with a chemical called polyethylene glycol, which encourages the fat in cell membranes to mesh. The muscles and blood supply would be sutured and the recipient kept in a coma for three or four weeks to prevent movement. Implanted electrodes would provide regular electrical stimulation to the spinal cord. When the recipient wakes up, Canavero predicts they would be able to move and feel their face and would speak with the same voice. He says that physiotherapy would enable the person to walk within a year.

I think we are now at a point when the technical aspects are all feasible…This is why I first spoke about the idea two years ago, to get people talking about it. If society doesn’t want it, I won’t do it. But if people don’t want it in the US or Europe, that doesn’t mean it won’t be done somewhere else. I’m trying to go about this the right way, but before going to the moon, you want to make sure people will follow you.
