Acute phase treatment. If there is dyspnea and shortness of breath, mechanical ventilation should be carried out promptly. 2. Pharmacological treatment: When PDA shunt is large, it can lead to cardiomegaly, idiopathic dyspnea and heart failure, in addition to active anti-heart failure treatment, indomethacin can be tried to treat arterial catheterization. 3. Surgical treatment: For PDA combined with infected endarteritis, surgical treatment can be performed 3 months after infection control. If the infection cannot be controlled, surgical ligation or arteriotomy can be performed followed by antibiotics, which is also a treatment for infected arteritis. 4. Interventional therapy.
