Abstract
3 cases due to in-stent stenosis from excessive granulation tissue. The mean time to in-stent stenosis was 188 days. Stent migration into the mediastinum occurred in 1 patient, requiring replacement with a wider, longer stent. Two patients required repeat insertion of SEMS after removal, due to severe bronchomalacia. The mean time between stent replacements was 38 days. Conclusion: In patients with high-grade BD SEMS offers prospects for successful outcome. SEMS are known to be associated with significant granulation tissue formation. In our opinion this property of SEMS provides a platform for healing of dehiscence and in time, peribronchial soft-tissue support grows in to cover the defect allowing stent removal.
