Dynamic Y Stent Fractures in Crescentic Tracheobronchomalacia

Abstract

Endobronchial stents have been used occasionally to treat benign conditions such as tracheobronchomalacia (TBM). This report describes a unique case of a patient with crescentic TBM in whom Dynamic Y stent was placed on 2 separate occasions to control symptoms and resulted in identical posterior wall stent fractures within a year of stent placement, both times. A silicone Y stent was substituted for the dynamic stent, and it has been effective in controlling symptoms for 9 months without complications. A literature review of cases of fractured Dynamic Y stents is made and factors affecting the choice of stent type for crescentic TBM are explored.

Bronchoscopy-Guided Intervention Therapy With Extracorporeal Membrane Oxygenation Support for Relapsing Polychondritis With Severe Tracheobronchomalacia: A Case Report and Literature Review

“…However, long-term follow-ups and prognostic data are generally lacking. In addition, long-term airway stent implantation also has many complications, such as displacement, fracture, granulation hyperplasia, airway bleeding, and mucus obstruction, which may affect the efficacy and subsequent treatment (20)(21)(22).…”

“…However, long-term follow-ups and prognostic data are generally lacking. In addition, long-term airway stent implantation also has many complications, such as displacement, fracture, granulation hyperplasia, airway bleeding, and mucus obstruction, which may affect the efficacy and subsequent treatment ( 20 – 22 ). The literature shows that tracheobronchoplasty has a better effect on severe TBM caused by COPD and can significantly improve recent clinical symptoms and quality of life ( 19 ).…”
