title: Palliation of malignant tracheal stenosis with a second implantation of an expandable metallic stent under endotracheal intubation.
abstract: A 74-year-old man was admitted with respiratory failure and treated for tracheobronchial stenosis due to metastasis of renal cell carcinoma. It improved after implantation of an expandable metallic stent (EMS). One year later, the metastatic tumor at the near distal side of the EMS increased; eventually serious respiratory failure occurred again. However, the delivery catheter of EMS could not be inserted by the usual procedure because there was a strong tracheobronchial curve. Finally it passed along the inside of the endotracheal intubation tube. The respiratory failure was improved by the second implantation of EMS with the method of stent in stent. EMS is often effective in a case with a strong curve and twist of the trachea/bronchi. It was also considered one way of letting the delivery catheter pass inside the endotracheal intubation tube if the patient's respiratory condition was maintained.
