Abstract

Anterior mediastinal tracheostomy (AMT) is performed to establish an airway after resection of advanced tumors in the cervicothoracic region. We report a case of successful placement of a covered retrievable self-expandable nitinol stent for a stoma stricture that developed after AMT in a patient with adenoid cystic carcinoma of the trachea. Two stent placements and removals, at two and three months after their initial placement, were performed due to loosening of the stents. Although we did not achieve long-term results as the patient died of massive hemorrhage, the stent placement was both feasible and safe, thus suggesting that temporary stent placement may be a valuable option for treating stoma stricture occurring after AMT.

  Fig. 1 Temporary stent placement for the stricture of the stoma after anterior mediastinal tracheostomy for adenoid cystic carcinoma. A, B. Axial and reconstructed CT images show a tight stricture (arrows) at the ostium of the anterior mediastinal tracheostomy. C. A 12-mm-diameter, 3 cm-long, covered retrievable self-expandable nitinol stent was placed under fluoroscopic guidance to treat the stricture. There is a waist formation (arrows) of the stent at the stricture. D. The proximal end of the stent was exposed outside the skin. E. On bronchoscopy obtained after stent placement, the distal end of the stent lies at the carina level. F. A CT scan obtained after two months following the temporary stent placement, shows substantial widening of the previous stricture (arrows).
