Summary

Mounier-Kuhn syndrome (MKS), or congenital tracheobronchiomegaly, is an entity characterized by dilation of the trachea and bronchi, associated with respiratory infections.The main signs and symptoms are cough, bulging and purulent expectoration, digital clubbing, dyspnoea, and wheezing.Some of these symptoms are believed to be due to excessive collapse of the intra-thoracic trachea and bronchi, resulting in airways obstruction of more than 50% . The purpose of this study is to identify and reduce tracheal collapse.

Conditions

  • Mounier-Kuhn Syndrome

Interventions

PROCEDURE

Non invasive ventilation - Continuous Positive Airway Pressure

To identify, through bronchoscopy, the prevalence of collapse and whether it is possible to counteract an optimum pressure generated by NIV with CPAP that reduces tracheal and bronchial collapse in patients with SMK; To study the frequency of OSAS in patients with MKS ; Record reversal of collapse with CPAP using chest tomography; To identify the impact of CPAP on the distribution of pulmonary ventilation through the analysis of electrical impedance tomography.
