Patent ductus arteriosus... Is there a self-healing one?

summary

The ductus arteriosus was originally the normal blood flow channel between the pulmonary artery and aorta in the fetal period. Due to the dysfunction of pulmonary respiratory function at this time, the pulmonary artery blood from the right ventricle enters the descending aorta through the catheter, while the left ventricle blood enters the ascending aorta. Therefore, the ductus arteriosus is necessary for the special circulation mode in the embryonic period. After birth, the baby's lung swells and undertakes the function of gas exchange. The pulmonary circulation and systemic circulation perform their respective duties. Soon, the catheter will be closed automatically due to disuse. If the patent ductus arteriosus is formed due to continuous non closure, surgical treatment should be chosen at this time.

Patent ductus arteriosus... Is there a self-healing one?

Generally speaking, patent ductus arteriosus belongs to congenital heart disease. Children within one year old have the possibility of self closure. Generally speaking, the possibility of self healing of patent ductus arteriosus is very small. If they are over two years old, they can choose minimally invasive surgery, occlusion or thoracotomy repair surgery.

The main cause of patent ductus arteriosus in infants is heredity. In the fetal period, any factors that affect the development of heart embryo may cause heart malformation, such as rubella, influenza, mumps, coxsackievirus infection, diabetes, hypercalcemia, etc. in pregnant women, exposure to radiation; Pregnant women take anticancer drugs or metformin and other drugs.

The closure of ductus arteriosus should be performed before school age. If the shunt is large and the symptoms are serious, the operation should be performed earlier. Older age, pulmonary hypertension, increased risk of surgery, and poor efficacy. When suffering from bacterial endarteritis, the operation should be postponed, but if the drug control of infection is not effective, the operation should still be strived for, and the drug therapy should be continued after the operation, so that the infection can be controlled quickly.

matters needing attention

Patent ductus arteriosus in a few weeks after surgery there will be massive bleeding, will bring a variety of discomfort to the body, so we should do a good job in postoperative nursing, to avoid all kinds of infection, resulting in the sequelae of surgery.
