Abstract
Saccular aortic aneurysms are rare pathologies which are true aneurysms that contain all histological layers of the aorta. Although an aortic diameter of 3 cm or more is generally accepted as an aneurysm, the surgical indication age is usually above 5 cm. SAA, on the other hand, can be operated by its diagnosis, since they are dysmorphic aneurysms and more prone to rupture regardless of their diameters. As in our case, a SAA may cause acute coronary syndromes, patients may apply with acute myocardial infarction. Although a SAA involving a coronary ostia is a very rare cause of acute coronary syndrome, it still should be kept in mind. In November 2022, A 57 year old male patient with inferior AMI due to an occlusive complication of a sacculary aneurysm involving the right coronary artery (RCA). Consequently, the patient was operated urgently. Aneurysm was excised and a graft coronary artery bypass was performed to RCA. Postoperative follow-up and treatment were uneventful and the patient was discharged on the 11th postoperative day
