Ascending Aorta Saccular Aneurysm: An Unexpected Reason For Acute RCA Occlusion

Case Report

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.
