シリコンチユーブ長期挿入による外傷性気管狭窄の治療例

抄録

A 22 year-old male with a long tracheal cannula came under the authors care. The trachea was found to be granulomatous and remarkably stenosed 3 cm long at the site 4 cm above the tracheal bifurcation. A silicon tube was inserted into the thoracic trachea over its stenosis and the upper end of the tube was fixed in the trachea just under the tracheal stoma. The patient was discharged after this procedure and lived an ordinary life for 14 months. The silicon tube gave him no disturbance in the respiration. After the tube was removed through the larynx, the tracheal wall was found smoothly epithelized without any following restenosis. This method should be recommended in such a case of granulomatous tracheal stenosis in the thoracic region in which the surgical procedure may be dangerous.
