[Four cases of hemorrhages after surgical repair of iatrogenic tracheal stenosis (author's transl)].

In our series of 23 patients, operated 27 times, for a iatrogenic stenosis of the trachea, there were 4 deaths by hemorrhage of the innominate artery. Three resulted from shearing of the artery by the tracheal sutures. One came from erosion by a tracheostomy cannula. This fatal complication should be prevented by preserving healthy tissues between the artery and the trachea.
