How many mm should an adult's patent ductus arteriosus be closed before surgery is required?

Patent ductus arteriosus is one of the common types of congenital heart disease in children. In adults, patent ductus arteriosus is usually treated with surgery if it exceeds 2 mm, but it is necessary to combine clinical symptoms to determine whether surgery is necessary. If there is no abnormality in the adult's body, surgery is generally not required. If there is an abnormality in the body, surgery may be required. The specific analysis is as follows:

1. No need: If it is found during a physical examination that the part of the patent ductus arteriosus is small, it is just a simple patent ductus arteriosus of 2 mm in adults, the shunt is not particularly serious, and there are no obvious clinical symptoms in the body, then generally no special treatment is required and regular follow-up observation is required.

2. Need: If the patent ductus arteriosus in adults is caused by congenital malformation, the condition is serious, and there are also symptoms such as dyspnea, atrial fibrillation, and pulmonary hypertension. When pulmonary hypertension is severe, it is easy to compress the recurrent laryngeal nerve and cause hoarseness. In this case, it is necessary to take interventional occlusion surgery or surgical repair surgery under the guidance of a doctor to avoid delaying treatment and affecting health.

If the symptoms are severe, it is recommended that the patient go to the hospital in time to complete the relevant examinations and the doctor will formulate an appropriate treatment plan. It is not recommended that the patient blindly seek medical treatment before a diagnosis is made, so as not to damage the health of the body.
