Abstract
Saccular type of thoracic aortic aneurysm is a rarely seen phenomenon. Here, we present a case of saccular-type aortic aneurysm admitted to coronary care unit with a diagnosis of acute coronary syndrome. A 63-year-old woman presented to our clinic with chest pain lasting for 2-3 hours. Because her chest pain persisted despite intensive medical treatment, she underwent coronary angiography. Coronary arteries appeared normal but a saccular type aneurysm of ascending aorta was detected on aortography. The patient underwent urgent surgery. The aneurysmal segment was resected and tube graft inserted. The patient was discharged without any postoperative complication.
