What is patent ductus arteriosus

summary

A friend gave birth to a child not long ago. Later, I heard that the child had a disease called patent ductus arteriosus. Let's introduce what is patent ductus arteriosus?

What is patent ductus arteriosus

First of all, the ductus arteriosus was originally the normal blood flow channel between the pulmonary artery and the aorta in the fetal period. Because of the pulmonary respiratory dysfunction, the pulmonary artery blood from the right ventricle enters the descending aorta through the catheter, while the left ventricle blood enters the ascending aorta, so the ductus arteriosus is necessary for the special circulation mode in the embryonic period.

Secondly, after birth, the lung swells and undertakes the function of gas exchange. The pulmonary circulation and systemic circulation perform their respective duties. Soon after, the catheter is self closed due to disuse. Such as continuous non closure and the formation of patent ductus arteriosus. Surgery should be performed to interrupt the blood flow. Patent ductus arteriosus (PDA) is a common congenital cardiovascular malformation, accounting for 12% - 15% of the total number of congenital heart diseases. About 10% of the cases had other cardiovascular malformations.

Finally, there are many reasons for children to get this disease. Generally, the internal factor is mainly genetic, and the influence on the fetus during pregnancy is also one of the important factors. Especially in the fetal period, any factor that affects the development of heart embryo may cause heart deformity, such as rubella, influenza, mumps, Coxsackie virus infection, diabetes, high blood pressure The pregnant mother was exposed to radiation; the pregnant mother took anticancer drugs or metformin and other drugs.
