Background
Congenital heart disease (CHD) such as patent ductus arteriosus (PDA) could be a predisposing factor of infective endarteritis (IE).
Mycotic aneurysm is an aneurysm due to an infection of the arterial wall. These are uncommon lesions, with a great potential for hemorrhage or sepsis. Since infectious aneurysm of the aorta has a tendency to expand rapidly in size and rupture, early diagnosis is very important.
We present the case of a 23 year old woman, in whom the diagnosis of patent ductus arteriosus complicated by endarteritis of both pulmonary artery and descending aorta was diagnosed, complicated by mycotic aneurysm of the descending aorta.
After two weeks of antibiotic treatment, the patient underwent surgical removal of the vegetation, closure of the mycotic aneurysm and section suture of the patent ductus arteriosus.
