Ultrasonographic evaluation of a vascularized tracheal transplantation

Tracheal stenosis is a frequent problem that in most cases is a complication of prolonged intubation. When the stenosis impairs more than half of the length of the trachea, it is not technically feasible to make a resection with a terminoterminal anastomosis. In this clinical context, tracheal transplantation is a therapeutic alternative. We report the case of a patient in whom a vascularized tracheal transplantation was performed successfully and emphasize the importance of an imaging evaluation, particularly with ultrasonography.
