ABSTRACT
With the popularization and development of lung CT scanning and technology of bronchoscopy in pediatrics,central airway obstruction has been diagnosed more and more.Central airway obstruction can affect airway ventilation and secretion discharge,such children are often hospitalized for repeated pneumonia,and sometimes need mechanical ventilation but may be difficult weaning from it. Malnutrition,hypoxic brain injury and backward growth and development are often associated. In the past,central airway obstruction has been mainly treated by surgery. However,with the development of minimally invasive technology of bronchoscopy in children,airway stent implantation has become an effective and alternative treatment recently. This article reviews the types of pediatric central airway obstruction,indications and contraindication of airway stent implantation,types and selection of stent,and the procedures of stent implantation.
