Utility of Tracheal Stent for Tracheal Stenosis Caused by Thyroid Tumor

Some cases of thyroid malignant tumors and thyroid lymphoma were reported to have caused tracheal stenosis and choking. Benign thyroid tumors with dyspnea due to tracheal stenosis are very rare. We experienced a benign thyroid tumor that caused tracheal stenosis and dyspnea. In the preoperative CT, there was tracheal stenosis due to enlarged bilateral thyroid lobes and the width of the stenotic lumen was 7mm. Subtotal thyroidectomy improved the dyspnea. Postoperative histopathologic examination confirmed follicular adenoma without malignant lesions or chronic thyroiditis. On postoperative CT, the tracheal stenosis had improved and the lumen had increased to 15mm. The above findings would suggest that it should be keep in mind that even benign thyroid tumors with tracheal stenosis of less than 7mm in the lumen have the possibility of causing dyspnea.

Post Intubation

Airway stent insertion is a procedure increasingly used in patients with complex post-intubation tracheal stenosis (PITS) who are unfit for or refuse surgery [1-3]. Very recently, a new self-expanding metallic stent (Alveolus TB-STSTM, Alveolus Inc., Charlotte, NC, USA) which is supposed to be easy to remove and for which indication for the treatment of benign tracheobronchial conditions has been obtained from the FDA, has been put on the market and is under evaluation. We report on a very unusual complication of an Alveolus tracheal stent in a patient with PITS.

Mediastinal Tracheostomy

We describe the management of a tracheoesophageal fistula due to a damaged tracheal stent, which was first inserted to treat tracheal stenosis. A 29-year-old woman with a history of treated epilepsy had a seizure and suffered from smoke inhalation during a fire. Breathing difficulties appeared and gradually worsened; consultation was obtained two years afterward. After undergoing a thorough examination, the patient was diagnosed with tracheal strangulation. A noncovered, metallic stent was inserted. When the patient was 37 years old, she was admitted to our hospital for the treatment of a tracheoesophageal fistula. We diagnosed it as a tracheoesophageal fistula due to the collapse of the damaged tracheal stent toward the esophageal side, and we decided to perform a mediastinal tracheostomy. Granulation may be formed in the circumference of a stent that has been present for a prolonged period, and removal of the stent may become difficult. This case suggests that insertion of a noncovered, metallic stent is contraindicated for a benign disease.
