Arterial ductus arteriosus does not usually cause recurrent fevers, but complications such as pneumonia caused by arterial ductus arteriosus may lead to recurrent fevers in patients. The pathogenesis of arterial ductus arteriosus is unclear, but preterm labor, the presence of a viral infection in the mother during pregnancy, or exposure to radiation may induce arterial ductus arteriosus in the fetus. Clinically, arterial ductus arteriosus usually presents with symptoms such as cough, dyspnea, feeding difficulties, and chicken chest, but it does not usually cause recurrent fever in patients. However, the unobstructed ductus arteriosus can increase blood flow to the lungs, leading to lung infection, which in turn induces the patient to develop pneumonia. Pneumonia can cause coughing, shortness of breath, and recurrent fever. In case of arterial ductus arteriosus, it is necessary to consult a doctor in time and take active treatment under the doctor’s guidance to prevent all kinds of complications.
