I saw the documentary about the fraud surgeon in Europe that used plastic tracheas. They had no way to “connect” to the patients body or get a blood supply. But….. theoretically speaking, why would a transplanted trachea even need a blood supply? Its entire job is just to stay there as an opening for air to come in and out, it doesn’t actually do anything.
In: Biology
Doesn’t actually doo anything doesn’t mean they aren’t alive. Any living tissues require circulation supply to stay alive.
The transplanted trachea isn’t completely plastic, synthetic material only serves as a temproary frame, stem cells grafted onto the frame is expected to grow into useful tissue and form a new real trechea, which apparently didn’t work if the living tissue did not receive enough circulation.
