Widening of the internal diameter of the pulmonary artery may be physiologic, or it may be caused by arterial ductus arteriosus or ventricular septal defect, etc. It can be relieved by surgical treatment.
1. Physiologic: widening of the internal diameter of the pulmonary arteries may be caused by congenital wider pulmonary arteries without other obvious clinical symptoms, at this time can be temporarily observed without treatment.
2. Arterial ductus arteriosus: the duct between the pulmonary artery and the aorta is not closed. It can be treated by percutaneous arterial ductus arteriosus occlusion or cut and suture surgery.
3. Ventricular septal defect: It is a congenital malformation of the heart and can be treated by surgery such as ventricular septal defect repair and ventricular septal defect occlusion.
In case of widening of the internal diameter of the pulmonary artery, you should go to the hospital in time, complete the relevant examinations to clarify the cause of the disease, and take symptomatic treatment under the guidance of the doctor, avoiding unauthorized use of medication or treatment.
