RESUMO
O objetivo do presente estudo foi caracterizar a traqueobroncomalacia (TBM) e excessive dynamic airway collapse (EDAC, colapso dinâmico excessivo das vias aereas). Embora a TBM e o EDAC, caracterizados por uma redução de 50% ou mais da luz, sejam descritos com frequencia crescente na forma de relatos de casos clinicos, faltam dados sistematizados que permitam o pronto diagnostico e a distinção entre TBM e EDAC. As tecnicas endoscopicas tem papel fundamental no diagnostico e podem ser uma alternativa para o tratamento de TBM e EDAC. É evidente a necessidade de estudos mais aprofundados acerca de TBM e EDAC que permitam o pronto reconhecimento e o tratamento adequado dessas entidades e das doenças subjacentes, contribuindo para uma melhora na qualidade de vida dos pacientes.
The objective of this review was to characterize tracheobronchomalacia (TBM) and excessive dynamic airway collapse (EDAC). There have been clinical case reports of TBM and EDAC, both of which are characterized by a ¡Ý 50% reduction in the crosssectional area of the tracheobronchial lumen, and the number of such reports is increasing. However, there are no systematicdata that would facilitate prompt diagnosis and allow distinctions to be drawn between TBM and EDAC. Endoscopic techniques play a key role in the diagnosis of both conditions and might represent an alternative means of treating patients with TBM or EDAC.There is a clear need for further studies of TBM and EDAC in order to develop strategies for the prompt recognition andproper treatment of these entities, as well as of the underlying diseases. The use of such strategies could lead to an improvement in the quality of life of patients within this population.
