New insights in excessive dynamic airway collapse (EDAC) and tracheobronchomalacia

Abstract

Excessive central airway collapse (ECAC) encompasses both excessive dynamic airway collapse (EDAC) and tracheobronchomalacia (TBM). This review aims to synthesize current knowledge of ECAC, including its pathophysiological mechanisms, clinical presentation, diagnosis and management strategies. It also addresses existing gaps and controversies in our current understanding. Lastly, it highlights recent insights into the understanding and management of ECAC, offering a comprehensive overview of the evolving landscape of this condition.
