INTRODUCTION:
Wheezing is a common symptom of respiratory infections in infants and young children, and about 30 percent of children develop wheezing from respiratory infections by the age of three【1】 . In addition to infection, the Anatomic structure is abnormal, such as: Extrinsic to airway,Lymphadenopathy, Tumor,Diaphragmatic hernia,Vascular ring/aberrant vessel,Intrinsic to airway,Tracheomalaci, Foreign body, Endobronchial tuberculosis, Vocal cord dysfunction, Bronchopulmonary dysplasia,Congestive heart failure, Congenital lobar emphysema and Genetic/metabolic diseases also caused wheezing【2】 .
Congenital heart disease is an important risk factor for infants hospitalized for wheezing【3】 . Patent ductus arteriosus (PDA) is the third most common congenital heart disease in children[4]. Interventional therapy is an effective way to treat patent ductus arteriosus and can reduce the risk of hospitalization for pneumonia or wheezing in children with PDA【5,6 】.
However, this paper reports a case of wheezing due to obstruction pressure on the airway after interventional treatment of patent ductus arteriosus. This has not been reported before, and a review of relevant literature was also carried out.
