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 SaO_2 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 insertionmultiple organ failure(n=3),cachexia(n=1)and pulmonary infection caused by gastrobronchial 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 earina was a simple and safe procedure and with a good short-term clinical efficacy.
