Giant Aneurysm of Ascending Aorta and Aortic Arch: A Report of a Rare Case.

ABSTRACT

A thoracic aortic aneurysm is considered giant when its diameter exceeds 10 cm. We report a rare case of a giant aneurysm involving the ascending aorta and aortic arch in a 40-year-old man, initially diagnosed as an acute aortic dissection. The patient underwent emergency surgery, during which the ascending aorta and aortic arch were replaced under deep hypothermia and circulatory arrest with selective antegrade cerebral perfusion. Strong teamwork resulted in a favorable postoperative course for the patient.
