ABSTRACT
RESUMEN La traqueobroncomalacia es una enfermedad de la vía aérea central caracterizada por una debilidad de la pared, con disminución dinámica de la luz de la tráquea y grandes bronquios principalmente durante la espiración. Genera síntomas crónicos que pueden evolucionar hasta la falla respiratoria grave, frecuentemente diagnosticados de forma errónea como asma o enfermedad pulmonar obstructiva crónica (EPOC). Presentamos el caso de una paciente femenina de 70 años, con antecedente de artritis reumatoide y múltiples internaciones por cuadros respiratorios infecciosos en los 3 años previos.
ABSTRACT Tracheobroncomalacia is a disease of the central airway due to weakness of the wall with dynamic narrowing of the lumen of the trachea and mainstem bronchi during exhalation. It produces chronic symptoms that can progress to severe respiratory failure, often misdiagnosed as asthma or chronic obstructive pulmonary disease (COPD). We report the case of a 70-year-old female patient with a history of rheumatoid arthritis and multiple hospitalizations for recurrent respiratory infections over the past 3 years.

CONTEXT: Tracheobronchomalacia (TBM) results from structural and functional abnormalities of the respiratory system. It is characterized by excessive collapse: at least 50 percent of the cross-sectional area of the trachea and main bronchi. In this paper, we present a rare case of a patient with TBM who first presented with stridor and respiratory failure due to exacerbation of chronic bronchitis. CASE REPORT: An 81-year-old Caucasian man was admitted presenting coughing, purulent sputum, stridor and respiratory failure. He had a medical history of chronic obstructive pulmonary disease (COPD) and silicosis and was a former smoker. Axial computed tomography on the chest revealed marked collapse of the trachea in its middle third. Bronchoscopy showed characteristics compatible with TBM. He was treated with noninvasive ventilation, without any good response. Subsequently, a Dumon Y stent was placed by means of rigid bronchoscopy. After the procedure, he was discharged with a clinical improvement. CONCLUSION: TBM is fatal and often underdiagnosed. In COPD patients, stridor and respiratory failure may be helpful signs that should alert physicians to consider TBM as an early diagnosis. Thus, these signs may be important for optimizing the treatment and evolution of such patients.
CONTEXTO: Traqueobroncomalácia (TBM) é resultado de alterações funcionais e estruturais do aparelho respiratório. É caracterizada pelo colapso excessivo de pelo menos 50 por cento da área de secção transversal da traqueia e dos brônquios principais. Neste trabalho, descrevemos um raro caso de paciente com TBM que primeiro apresentou estridor e insuficiência respiratória devido à exacerbação da bronquite crônica. RELATO DE CASO: Homem de 81 anos de idade, caucasiano, foi admitido apresentando tosse, expectoração purulenta, estridor e falência respiratória. Ele apresentava história médica prévia de doença pulmonar obstrutiva crônica (DPOC), silicose e era ex-tabagista. A tomografia axial computadorizada de tórax revelou marcado colapso da traqueia em seu terço médio. A broncoscopia mostrou aspectos compatíveis com TBM. Foi submetido a ventilação não invasiva, sem boa resposta. Na sequência, foi colocado stent Dumon em Y por broncoscopia rígida. Após o procedimento, o paciente teve alta com melhora clínica. CONCLUSÃO: TBM é uma entidade fatal e muitas vezes subdiagnosticada. Em pacientes com DPOC, o estridor e a insuficiência respiratória podem ser sinais úteis que devem alertar os médicos a considerar TBM como diagnóstico precoce. Assim, pode ser importante para otimizar o tratamento e a evolução dos pacientes.

Objective. To study the prevalence of associated airway anomalies in infants presenting with moderate to severe laryngomalacia. Methods. Eighty three symptomatic infants with recurrent respiratory symptoms including wheeze and cough diagnosed as moderate to severe laryngomalacia based on their clinical and direct laryngoscopic findings were subjected to fiberoptic bronchoscopy (FOB) during the period March 2007 to February 2009 in the Department of Pulmonology, Institute of Child Health and Hospital for Children, Chennai, India. Analysis of the clinical features, radiological findings and associated lower airway anomalies by FOB was done. Results. Lower airway anomalies were demonstrated in 40 (48%) infants of the study population. Tracheomalacia was the most common lower airway anomaly 24(29%) followed by bronchomalacia 8(10%) and tracheobronchomalacia 6 (7%). (4:1:1). Conclusion. Infants with moderate and severe laryngomalacia should be evaluated with flexible fibreoptic bronchoscopy to rule out associated lower airway lesions.
