Objective To discuss the clinical application of internal stentin tracheal stricture.Methods The selfexpanding nitinol stent was introduced and displayed by an instrument with a tube in a sheath or after pre-dilation with PTA dilatation catheter.Results 42 cases with tracheal stricture were treated successfully.In 24 cases,tracheal stents were introduced,in 11 cases,broncheal stents were done and in 7 cases,tracheal and broncheal stents were done.Shortness of breath was relieved immediately.Follow-up study of the 42 cases for 3-43 months showed that the stent remained in the original position and the tracheal pathway was patent.Conclusion It is an effective method to treat tracheal stricture by means of self-expanding nitinol stent.
