Macchiarini, famed for his pioneering use of stem cells in regenerative surgery, was reported to the Swedish authorities by four doctors as early as 2014. "Much went wrong in connection with Macchiarini's transplants of synthetic trachea," said Asplund in a statement when he presented the results of the inquiry on Wednesday. There were shortcomings in how the decisions about the transplants were made and how they acted on existing laws. But he added that there had not been "an immediate life threat" in either of the cases when the transplants were carried out. Karolinska bosses said later on Wednesday that the hospital would now be looking into another four cases involving Macchiarini to see if there had been any complications or wrongdoing.
