Abstract

Drs Eric Mair and David Parsons, San Antonio, Tex, presented their experience with the treatment of severe bronchomalacia using an expanding endobronchial stent, at the recent meeting of the American Society of Pediatric Otolaryngology in San Diego, Calif. A neonate with severe left mainstem bronchomalacia, carbon dioxide retention, air trapping, mediastinal shift, and recurrent cardiopulmonary arrests was successfully treated by endoscopic placement of a stainless steel stent. The child died 4½ months later of problems unrelated to the stent. Autopsy results showed partial incorporation of the stent into the mucosa with only mild, nonobstructing granulations.

This experience prompted the authors to proceed with a study of endobronchial stenting, using the stainless steel stent vs an expandable polymeric woven stent in 50 piglets with surgically induced bronchomalacia. The polymeric stent proved superior in functional design and was associated with less granulation than the stainless steel stent.

Subsequently, the authors treated a
