A Giant Infected Coronary Artery Aneurysm

Abstract

A 77-year-old man was admitted to our hospital with femorofemoral bypass graft infection with methicillinresistant Staphylococcus aureus bacteremia. Following removal of the infected graft, intravenous vancomycin was administered. He became febrile again 19 days after surgery.Contrast-enhanced computed tomography (CT) showed a giant saccular aneurysm (10.5×6.2×6.5 cm) with luminal thrombus (Picture 1a, b). A smaller version of the same aneurysm (2.7×2.9×3.0 cm) was later observed on contrastenhanced CT performed at admission. Coronary angiogra-

Sudden cardiac death caused by a right coronary artery aneurysm complicated with acute myocardial infarction: a case report

“…There are many reasons for coronary artery aneurysm, such as Kawasaki disease, connective tissue disease, infection, and coronary artery stenting. [3][4][5] In this patient, we also evaluated the concentrations of thyroid hormone, antinuclear antibody, antineutrophil cytoplasmic antibody, and anticardiolipin antibody; all results are normal. The patient had no other medical, surgical, or traumatic history, and he did not remember febrile childhood disease consistent with childhood Kawasaki disease.…”
