A case of pulmonary infective endarteritis associated with patent ductus arteriosus: surgical closure under circulatory arrest.

A 35-year-old man was admitted to the hospital with prolonged high-grade fever. Chest computed tomography revealed multiple pulmonary infiltrations in both lungs, suggesting septic emboli. Echocardiography revealed patent ductus arteriosus and mobile large vegetations in the pulmonary artery. Because of uncontrollable infection and the imminent possibility of massive pulmonary embolism, he underwent transpulmonary surgical closure of the ductus and resection of the vegetations under hypothermic circulatory arrest using cardiopulmonary bypass. We report a rare case of open heart surgery in a patient with pulmonary infective endarteritis associated with patent ductus arteriosus.
