Abstract:
A coronary artery aneurysm(CAA) that exceeds 20 mm in diameter is rare. In this case report, we describe the operative correction of a giant right CAA measuring greater than 8 cm in diameter. A 51-year-old male with a history of Kawasaki disease at 7 years of age was admitted to our hospital for evaluation of an abnormal shadow on a chest radiograph. Multi-detector row computed tomography (MDCT) demonstrated a giant, 82-mm right coronary aneurysm in the right atrioventricular groove with a layered thrombus. The patient underwent aneurysmectomy and coronary artery bypass grafting using the right internal thoracic artery under cardiopulmonary bypass. The postoperative course was uneventful, and postoperative MDCT revealed complete resection of the aneurysm and good patency of the bypass graft. The patient was discharged on the 8th postoperative day in good health.
