Treatment of bronchomalacia in cystic fibrosis by silicone stent.

We report the case of a 15-year-old girl with cystic fibrosis and rapidly declining pulmonary function tests who was found to have collapse of the left main bronchus from bronchomalacia. She underwent successful deployment of an expandable silicone stent in the collapsed bronchus, after which her pulmonary function test results and her clinical picture markedly improved, obviating the need for immediate transplantation. A literature review yielded no prior reports of bronchomalacia in a cystic fibrosis patient being treated with a silicone stent. This case shows that a simple, effective treatment is possible for one cause of obstructive pulmonary function in cystic fibrosis.
