RESUMEN
El secuestro broncopulmonar es una anomalía congénita rara. La variedad intralobar representa el 75 % de los secuestros pulmonares y usualmente se presenta antes de los 20 años de edad. Se reportó una paciente de 59 años, con antecedentes de infecciones respiratorias bajas a repetición. En los estudios de imágenes de tórax se evidenció opacidad de contornos irregulares en hemitórax izquierdo. Fue intervenida quirúrgicamente con la sospecha de cáncer de pulmón y se realizó examen histopatológico del tejido pulmonar cuyos hallazgos macroscópicos y microscópicos se correspondieron con un secuestro intralobar.
Pulmonary sequestration is a rare congenital pulmonary malformation. Intralobar sequestrations account for 75% of all pulmonary sequestrations. Patients usually present it before the age of 20. A 59 years old female patient with a history of recurrent lower respiratory infections is reported here. In her chest imaging studies, irregular margins opacity was evident in her left hemithorax. She underwent surgery for suspected lung cancer. Diagnosis of intralobar sequestration was made after histopathological examination of the resected lung.
RESUMEN
Objective To discuss the relationship between pulmonary infection, offline difficulties and airway abnormalities and to discuss the type of airway abnormalities. Methods The clinical data of 43 patients of severe pneumonia with inspection of electronic fibro-bronchoscope in PICU from Feb 2008 to May 2010 were retrospectively analyzed. Results In the 43 cases,24 cases existel different degrees of airway abnormalities, most of airway cartilage softening,in 15 cases; laryngeal dysplasia in 3 cases; absence of the right bronchus and right lung in 1 case. Conclusion Many children may exist airway abnormalities,if they have such performance as the clinical manifestations of recurrent wheezing after birth, refractory respiratory infection or difficulties in clinical offline, the increase of PCO2 though the effective suction, paroxysmal cyanosis and excluded with heart disease. Those children should undergo inspection with electronic fibro-bronchoscope to confirm the diagnosis as early as possible.
