Pulmonary homograft repair of a mycotic aortic aneurysm in an infant.

Thoracic aortic aneurysms are rare in children and even more unusual in infants. The vast majority are mycotic. Frequently, those with mycotic thoracic aortic aneurysm do not survive and the diagnosis is made at autopsy. We present the case of an asymptomatic infant found to have a mycotic thoracic aortic aneurysm. The clinical course, diagnosis, and surgical repair of the aneurysm with pulmonary homograft are discussed.
