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. Patent ductus arteriosus... Is there a self-healing one? Next, I'd like to share my views with you.

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

Patent ductus arteriosus has a certain probability of self-healing. Within three months, the ductus arteriosus itself may be self-healing; If patent ductus arteriosus is not closed after three months, the possibility of self-healing is low through clinical observation. Therefore, it is suggested that the majority of patients with patent ductus arteriosus should be found early and treated early, rather than waiting for the disease to heal itself.

The ductus arteriosus is usually closed within 15 hours of birth. Even if the ductus arteriosus is not closed, it may self heal within three months. If the ductus arteriosus is thinner, it may close within one year. However, if the ductus arteriosus is thicker, it is not easy to heal. It needs to be treated by surgery or interventional occlusion for human intervention.

In general, after breathing oxygen, the lung tissue expands, and after gas exchange, the systemic circulation and pulmonary circulation begin to operate separately, and the pulmonary artery catheter can be closed by itself due to disuse.

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.
