Advances in the complications related to transcatheter closure of patent ductus arteriosus in children
Patent ductus arteriosus(PDA)is one of the most common congenital heart diseases in childhood.The prevalence of PDA is about 0.5％and PDA accounts for 5％-10％of congenital heart diseases.Continuous opening of the ductus arteriosus can affect children's growth and development.Meanwhile,PDA increases the possibility of pneumonia,infective endocarditis,neonatal necrotizing enterocolitis,and other diseases.Compared with traditional surgery,percutaneous interventional closure of PDA in children has a higher surgical success rate and shorter hospital stay.Clinical practice has proved that percutaneous interventional closure is the preferred method for children with PDA.However,transcatheter closure also has complications,including displacement,valvular regurgitation,hemolysis and thrombocytopenia.The review aims to illustrate the mechanism and treatment of the complications after PDA interventional closure,in order to increase the physician's awareness of those complications,reduce the incidence of the complications and improve the prognosis of the patients.
