The upcoming decade ought to be rich in medical milestones and new treatments, and we’re already off to a roaring start in 2010 — Belgian surgeons were able to place a transplanted trachea into a patient’s arm before placing her new windpipe in her neck, allowing it to grow rich with her own blood vessels. This helps keep the body from rejecting the new organ and also helps avoid the piles of immunosuppressant drugs most transplant patients have to take for the rest of their lives. Trachea transplants can be even more difficult than kidney or liver transplants because you can’t easily hook the organ up to the windpipe’s complex blood supply. Pretty cool stuff! {New England Journal of Medicine via BusinessWeek}
