Percutaneous tracheostomy is a technique that, reputedly, is simple to perform and causes few complications. It is routinely used in intensive care. We present two patients with tracheal stenosis. In one patient, we had to perform an anastomotic resection to cure the patient; in the other patient, we had to place an endoluminal conformer. To our knowledge, this complication has not been reported in association with the use of this technique.
