Congenital lobar emphysema
Enfisema lobar congénito
Resumen:
A case of lobar emphysema in a 10 day old infant is described. The upper left pulmonar lobule was affected as demonstrated by clinical and radiological signs. After lobectomy all sypmtoms subsided and the present condition status of the child is excellent. The anatomical study showed a marked reduction of the mesodermic complex throughout the bronchial tree of the affected lobule (car ilage, smooth muscle and elastic fibers. Each bronchial ramification is similar to another which is placed more periferically in a normal lung. Theincrease of collagen fibers in interlobulillar septa and the presence of abnormal macrophages with haemosiderine suggest that the process of pulmonar insufflation began "in utero", since 10 days are not sufficient to bring about such changes.
Se describe un caso de enfisema lobar agudo en un lactante de 10 días de edad, caracterizado clínica y radiológicamente. El lóbulo afectado era el lóbulo superior del pulmón izquierdo. La evolución fueexcelente luego que se practicara la lobectomíacorrespondiente.El estudio anatómico demostró una disminución de los componentes mesodérmicos (cartílago, músculo liso, fibras elásticas) de todo el árbol bronquial, de tal manera cada rama bronquial tiene una constitución semejante a otra situada mucho más periféricamente en un pulmón normal. El aumento del colágeno en los tabiques interlobulillares, así como la presencia de macrófagos anormales con hemosiderina, sugieren que el proceso de insuflación comienza "in utero" con los movimientos respiratorios del feto, ya que 10 días de evolución en nuestro caso no parecen ser suficientes para esos cambios.
