Hi doctor! My baby is 31 months old this year, but she still has a funnel shaped ductus arteriosus, the size of the tube is 5.6mm in the descending aorta, 3mm in the pulmonary artery, 6.2mm in the left-right shunt and has not yet grown. Pulmonary pressure, normal cardiac function. So the doctor asked me: "How to treat the funnel-shaped ductus arteriosus without pulmonary hypertension in children? Thanks for the advice doctor!

The ductus arteriosus is an important blood vessel that connects the main pulmonary artery and the aorta. Normally, the ductus arteriosus exists for 2-6 days after birth. If the ductus does not close after this time, it is called a persistent ductus arteriosus. Persistent ductus arteriosus in premature infants (Persistent ductus arteriosus) occurs when the ductus arteriosus does not close completely after birth.

Children with patent ductus arteriosus are susceptible to bronchitis, pneumonia, slow physical development, and malnutrition. Thoracoscopic ductus arteriosus clamping is a safe and effective method to treat patent ductus arteriosus.

Ductus arteriosus ligation surgery is indicated for cases where medical treatment fails to close the ductus or the ductus arteriosus is small, medium, and not calcified... Ductus arteriosus ligation technique must be performed according to standard procedures by a cardiologist.
