Recurrent Lower Respiratory Tract Infections in a Girl with Left Main Bronchial Stenosis / 소아알레르기및호흡기학회지

Congenital bronchial stenosis is a rare condition with variable symptoms of presentation. Affected patients are usually asymptomatic, but because of the reduced airway, cough, cyanosis and respiratory distress may be presented. We report a 19 month-old girl with a recurrent history of severe wheezing, dyspnea and cyanosis accompanied by lower respiratory tract infections. Young children with severe respiratory symptoms and no immunological abnormalities must be suspected of airway structural abnormalities.

Congenital Cardiopulmonary Anomalies in Infants with Recurrent Stridor and/or Respiratory Distress: Report of 3 Cases / 소아알레르기및호흡기학회지

Although laryngomalacia is the most common cause of congenital stridor in infancy, it is a benign, self-limited disease which usually resolves by the age of 18 months with no long- term sequelae. Nevertheless, infants who suffered from recurrent stridor and respiratory distress should be evaluated for other causes of stridor such as cardiopulmonary anomalies. We report 3 cases of infants who had recurrent stridor and respiratory distress from their early infancy. Case 1 had a double aortic arch and a tracheomalacia, case 2 had a hypoplasia of the right lung, and case 3 had a horseshoe lung as well as scimitar syndrome. Physicians should be alert for the possibility of the congenital cardiopulmonary abnormalities in infants with recurrent stridor and/or respiratory distress.
