Tracheobronchography for pediatric airway disease is still a valuable technique?

Abstract

Background: Congenital and acquired airway anomalies represent a relatively common albeit diagnostic and therapeutic challenge. Obtaining maximum definition of the abnormality is imperative prior to attempting surgical procedure because some tracheal lesions have a significant risk of mortality. Are tracheobronchography (TBG) and tracheobronchofluoroscopy (TBF) valuable or obsolete techniques?

Methods: We retrospectively reviewed all the diagnostic and interventional TBG-TBF requested by the multidisciplinary conference, during the last 10 years in a tertiary care hospital exclusively dedicated to pediatric patients.

Results: A total of 268 procedures performed in 60 pediatric patients (68% male, mean age 4,8 years), were reviewed. 41 diagnostic TBG-TBF were performed in a group of 34 patients with excellent result, without complications. A total of 175 procedures of tracheobronchoplasty guided by TBG-TBF were completed in a group of 25 patients. Seven bioabsorbable self-expanding stents were placed in the airway of 6 children.

Conclusions: Diagnostic TBG and TBF are still irreplaceable tools to evaluate pediatric airway disease, with many advantages over the newest imaging techniques. Interventional procedures of pediatric airways under the guide of TBG-TBF represent safe and effective treatment options in selected patients, with positive clinical impact.
