Diagnosis and treatment status quo of major aortopulmonary collateral arteries in congenital heart disease with decreased pulmonary blood flow / 国际儿科学杂志

ABSTRACT

The congenital heart disease with decreased pulmonary blood flow is one type of congenital heart disease characterized by reduced pulmonary blood flow. Common clinical types include tetralogy of Fallot，pulmonary atresia，double outlet right ventricle，and other complex malformations associated with pulmonary artery stenosis. Due to the lack of pulmonary blood supply from the right ventricle，children with this condition often have major aortopulmonary collateral arteries（MAPCAs）or the ductus arteriosus participating in pulmonary circulation for blood supply. Research has revealed that MAPCAs are important factors which cause the increase of mechanical ventilation time，intensive care unit stay time，complication rate and mortality after radical surgical treatment of congenital heart disease with decreased pulmonary blood flow. Therefore，the treatment of MAPCAs in perioperative period is crucial. This article summarizes the research progress of MAPCAs distribution and influence，diagnosis and evaluation，and treatment methods，to provide the reference for clinicians to standardize MAPCAs treatment.
