Remplacement de la trachée par l'aorte

In our patient, we used the abdominal aorta as a tracheal substitute but replaced the endoprosthesis with an exoprosthesis leaving the aortic lumen free. The result was also encouraging, but the absence of integration of the aortic tissue did not confirm the observations reported by others. Other hypotheses concerning the regeneration of the neotrachea should be put forward.
