What are the effective methods to treat patent ductus arteriosus? The high incidence of patent ductus arteriosus has caused many parents to panic. Everyone hopes that their children can grow up healthily, so everyone is afraid that their children will suffer from patent ductus arteriosus. However, sometimes the disease often appears around us inadvertently. At this time, we must treat it well. However, what are the effective methods to treat patent ductus arteriosus?

Drug treatment

Prevent and treat infective endocarditis, respiratory tract infection and heart failure. For premature infants with patent ductus arteriosus, 0.2-0.3 mg/kg of indomethacin or 20 mg/kg of aspirin can be used to inhibit prostaglandin synthesis and close the ductus.

Interventional treatment

That is, patent ductus arteriosus closure surgery, the indications are various types of PDA, the closure device selection: children with PDA diameter <0.3cm, choose mushroom umbrella. The operation is less invasive, safer, simple to operate, with fewer complications and a short hospital stay (usually 3 days).

Surgery

Thoracotomy surgery to ligate and cut the ductus arteriosus.

The surgical mortality rate caused by massive bleeding during ductus arteriosus closure varies depending on the quality of the ductus wall, the surgical method used to close the ductus, and the level of surgeon skills, and should generally be less than 1%. Simple ductus ligation or clamping may result in ductus recanalization after surgery, and the recanalization rate is generally above 1%. The recanalization rate after padded ligation is lower than the former two.

The long-term effect of ductus arteriosus closure depends on whether there are secondary pulmonary vascular lesions before the operation and their extent. Patients who undergo surgery before pulmonary vascular lesions occur can fully recover and live as long as normal people. Patients with severe and irreversible pulmonary vascular lesions will still have high pulmonary vascular resistance and heavy right heart load after surgery, and the effect is poor.

The above is an effective method for treating patent ductus arteriosus. In fact, there are many factors that cause this disease, which leads to the diversity of treatment methods for this disease. Therefore, everyone should choose the treatment method according to their own condition. Only such symptomatic treatment can have a good therapeutic effect.
