Tracheal stent in benign tracheal stenosis

Objective: To discuss the role of tracheal stent in benign tracheal stenosis.Methods: Eight cases of benign tracheal stenosis were implanted the tracheal stent with the guidance of accurate digital substrution angiography positioning.Results: All stents were implanted successfully for one time.There were altogether 9 stents implanted,including 5 tracheal stents,2 tracheal-bronchial stents and 2 bronchial stents.The symptoms of dyspnea and respiratory rapidity were quickly relieved after treatment.Conclusions: Placement of tracheal stent is safe and effective for treatment of benign tracheal stenosis.
