Use of the covered Y-shaped metallic stent in the treatment of airway stenoses involving the lower trachea and the tracheal carina: preliminary clinical study

Abstract

Objective: To describe a new kind of Y-shaped metallic stent delivery system and evaluate its feasibility and preliminary effect for managing multiple airway stenoses involving the lower trachea and the tracheal carina. Methods: The Y-shaped metallic stent delivery system consisted of three-tier structure. The inner-tier was composed of four parallel guiding tubes, which was used for two guidewires and two threads passing through, the middle-tier was delivery catheter, which contained the four guiding tubes, and the outer-tier was introducer sheath. Under the fluoroscopic guidance, 15 patients with multiple stenoses involving the lower trachea and the tracheal carina were treated with the new covered self-expandable Y-shaped metallic stents. Results: Stent placement in the tracheo-bronchial tree was technically successful in all patients with obliteration of the dyspnea immediately after stent placement, and SaO2 was increased form preoperative 75%-89% to postoperative 96%-99%. During follow-up a period of 3-58 weeks (M 22 weeks), all stenosis were resolved without stent-related complications, and the general physical of all 15 patents was improved with no occurrence of obviously dyspnea and bleeding. Karnofsky performance status (KPS) was improved from preoperative 26%-45% to postoperative 72%-95%. Five patients died of the following causes unrelated to stent insertion: multiple organ failure  More>>

Five patients died of the following causes unrelated to stent insertion: multiple organ failure (n=3), cachexia (n=1) and pulmonary infection caused by gastrobronehial fistula (n=1), and the remaining 10 patients were alive with no evidence of dyspnea at the time of this report. Conclusion: Deployment of the covered Y-shaped metallic stent with the use of Y metallic stent delivery system in the management of airway stenoses involving the lower trachea and the tracheal carina was a simple and safe procedure and with a good short-term clinical efficacy.
