*In a specially equipped hospital suite, two surgical teams will work simultaneously—one focused on Spiridonov and the other on the donor’s body, selected from a brain-dead patient and matched with the Russian for height, build and immunotype. Both patients—anesthetized and outfitted with breathing tubes—will have their heads locked using metal pins and clamps, and electrodes will be attached to their bodies to monitor brain and heart activity. Next, Spiridonov’s head will be nearly frozen, ultimately reaching 12 to 15 degrees Celsius, which will make him temporarily brain-dead.
Doctors will then drain his brain of blood and flush it with a standard surgery solution. A vascular surgeon will loop sleeve-like tubes made of Silastic (a silicone-plastic combination) around the carotid arteries and jugular veins; these tubes will be tightened to stop blood flow and later loosened to allow circulation when the head and new body are connected. Then the two teams, working in concert, will make deep incisions around each patient’s neck and use color-coded markings to note all the muscles in both Spiridonov’s head and that of the donor, to facilitate the reconnection.
Next comes the most critical step of all. Under an operating microscope, doctors will cleanly chop through both spinal cords—with a $200,000 diamond nanoblade, so thin that it is measured in angstroms, provided by the University of Texas. Then the rush is on: Once sliced, Spiridonov’s head will have to be attached to the donor’s body and connected to the blood flow within an hour. (When the head is transferred, the main vessels will be clamped to prevent air from causing a blockage.) Surgeons will quickly sew the arteries and veins of Spiridonov’s head to those of his new body. The donor’s blood flow will then, in theory, re-warm Spiridonov’s head to normal temperatures within minutes.*
That’s just the procedure, there is more to the article in the link provided.
If this works though… I can’t even fathom all the implications that will then result… and some may very well be pretty bad.
