Paolo Macchiarini — once a world-renowned surgeon for creating tracheas from cadavers and patients’ own stem cells – has been dogged for years by accusations of misconduct. Officials at his institution, Karolinska Institute, initially cleared him of many charges, but that all changed earlier this year, when Swedish Television (SVT) aired a series of documentaries about Macchiarini and his work. The series alleged, in part, that he operated on patients in Russia whose conditions were not life-threatening enough to warrant such a risky procedure. Such serious accusations caused a media storm, and prompted officials to take a second look at Macchiarini’s work. KI dismissed Macchiarini , and many others have resigned, including KI’s vice chancellor . Recently, two new reports critiqued KI’s role in the case , and Sweden’s Central Ethical Review Board found Macchiarini guilty of misconduct in a 2014 paper . We spoke with SVT producers Bosse Lindquist and Johannes Hallbom via email about the fallout from their series.
