PURPOSE: A metallic stent for tracheobronchial stenosis provides a possible solution for poststenting complications such as sputum retention. We describe our experience with a novel anatomy-conforming metal stent placement at the carina.
DESCRIPTION: A windowed stent was designed to match the tracheobronchial anatomy. The lateral window was used as a passage from the trachea to the contralateral main bronchus.
EVALUATION: Six windowed stents were placed in 6 patients (mean age, 52.3 years). Two patients received an additional short straight stent placed in the contralateral bronchus, forming an overall Y stent at the carina. All patients had immediate relief from respiratory distress, and no sputum retention or stent migration occurred during the subsequent treatment period. Follow-up data showed that 4 patients are still alive. One patient died 2 months after stent placement of postradiation hemoptysis, and another died of metastasis 14 months after stent placement.
CONCLUSIONS: This anatomy-conforming metal stent has several advantages and its application in carinal stenosis is both effective and safe.
