ABSTRACT

Objective To evaluate the therapeutic effects and experience of the tracheal stent implantation for the management of severe tracheal stenosis.Materials Thirteen patients with severe tracheal stenosis of various causes underwent high kilovoltage radiography and computed tomography for evaluating the site,form and extent of the stenosis including 10 at the trachea,1 at the right main bronchus and 2 at left main bronchus.The C2 catheter assisted with ultra-slipping guide wire was inserted into the trachea under fluoroscopy and then a replaced high shoring guide wire was pushed through the stenotic segment and retained the stent. Results All stents were implanted successfully with successful rate 100% together with dyspneic improvements.The mean survival time was 6.2 months for patients with malignant neoplasm.One patient with benign tracheal stenosis has been followed-up for 5 years without restenosis. Conclusions The tracheal stent implantation is an effective means for severe tracheal stenosis.
