Surgeon Reveals Head Transplant Plan, But Patient Steals the Show

ANNAPOLIS, Md.—Valery Spiridonov looks impossibly small. He is dressed in all white, from his white button-down shirt to the white socks on his feet, which dangle at the ends of white pants and a white blanket. Breaking up the look is a black strap, which holds him to a motorized wheelchair.

He uses his left hand, which he can still move, a little bit, to steer the wheelchair into a hotel meeting room. There, he confirms that he would like to be the first person ever to have his head transplanted onto a new body.

Spiridonov flew from Russia to be at this conference, the American Academy of Neurological and Orthopaedic Surgeons (AANOS). He joined the surgeon proposing to do the transplant, Sergio Canavero of Turin, Italy. Canavero had built up his talk, a keynote address, for months, promising a big reveal of his plans to transplant Spiridonov’s head onto a donor body. (For background, see my earlier blog post and a good overview at New Scientist.)

The meeting is small, maybe 100 or fewer surgeons, and held in a very normal-looking Westin hotel in Annapolis, Md. Conference organizer Maggie Kearney spent much of the day turning away reporters in anticipation of a packed room. She says that in 15 years, she can’t remember a reporter ever attending the surgical conference before.

By the end of Canavero’s three-hour-long presentation (it was supposed to be an hour and a half, Maggie tells me), most of the reporters in the room seem worn out, and a bit confused about what the fuss was all about.

Canavero reviewed, at length, the scientific literature on spinal cord injury and recovery, regrowth of various parts of the central nervous system, and why some of the basic assumptions of neurosurgery are wrong. Throughout the lecture, he would occasionally point to Valery Spiridonov, his wheelchair parked near the stage, and make a declaration (“Propriospinal tract neurons are the key that will make him walk again!”).

Answering detractors’ comments that the transplant could be “worse than death” or could drive Spiridonov insane, Canavero asked Spiridonov directly, “Don’t you agree that your [current] condition could drive you to madness?”

Spiridonov answered quietly in the affirmative.

His condition is grave: a degenerative motor neuron disease that is slowly killing him. “I am sure that one day gene therapy and stem cells will fulfill their future,” Canavero said, “but for this man it will come too late.”

Finally, near the end of the talk, Canavero roughly outlined the surgery. He plans to sever the spinal cord very cleanly, using a special scalpel honed nano-sharp. (I could not see Spiridonov’s reaction to the special scalpel, but wondered.)

To minimize any die-off of cells at the severed ends during the transfer, Canavero says he will cut Spiridonov’s spinal cord a bit lower on the spine than needed, and the body’s a bit higher, and then at the last minute slice them again for a fresh cut. Then, add some polyethylene glycol (shown to stimulate nerve regrowth in animals), join the two ends together with a special connector, and voila. Electrical stimulation would then be applied to further encourage regrowth.

Of course, there’s a bit more to it, like reconnecting all the blood vessels and so forth, but Canavero is a neurosurgeon and the spinal cord was his focus.

Other neurosurgeons at the meeting responded cautiously to the proposal. The surgery might be possible “someday, but it is really a delicate situation,” said Kazem Fathie, a former chair of the board of AANOS.

Craig Clark, a general neurosurgeon in Greenwood, Mississippi, calls Canavero’s idea “very provocative.”

“There have been many papers over the years that have shown regeneration, but for one reason or another they didn’t pan out when applied clinically,” he said.

“There’s a lot of ethical questions about it,” said neurosurgeon Quirico Torres of Abilene, Texas. But Torres thinks it could be ethical to allow volunteers to do the surgery, and one day we might consider it normal. “Remember, years ago people were questioning Bill Gates: why do you need a computer? And now we can’t live without it.”

What’s Next?

Apart from the rundown of previous work on spinal cord injury, much of what Canavero said about the surgery was pretty much what he has said before. He supported his arguments for individual elements of a head transplant (or body transplant, if you prefer) but did not reveal any new demonstration of the entire procedure working in a person or an animal.

But Canavero has no shortage of confidence. He says he wants to do the surgery in America (implying Italy doesn’t have its act together enough to host a cutting-edge project like this).

“I have a detailed plan to do it,” he said, adding that he is asking Bill Gates and other billionaires to donate. He invited surgeons at the meeting to join his team, which could be enormous—more than 100 surgeons, he has said—and he wants team leaders in orthopedics, vascular surgery, and so on. These surgeons should work on the project full time for the next two years, he said, “and you will be paid through the nose, because I think doctors involved in this should be paid more than football players.”

After the talk, Spiridonov disappeared into a room to rest. When he came back out, he answered questions for the TV crews that had descended, sounding a bit weary of answering the same questions he’s been asked before. “What will happen to you if you don’t get this surgery?” a reporter called out. “My life will be pretty dark,” he said. “My muscles are growing weaker. It’s pretty scary.”

He looked tired.

During his interviews, I stepped aside to talk with his hosts in Annapolis, who are friends of a friend of the Spiridonov family. “He’s brilliant, he’s happy, he’s funny,” said Briana Alessi. “If this surgery were to go through and if it works, it’s going to give him a life. It’s life-changing. He’ll be able to do the things he could only dream of.”

And if not? “He’s taking a chance either way,” she said.

The final question he takes from the press: What do you say to people who say this surgery should not be done?

Spiridonov’s reply: “Maybe they should imagine themselves in my place.”
