An 84-year-old male with a medical history notable for prior thoracic endovascular aortic repair for thoracic aneurysm nine years ago presented to the emergency department with a chief complaint of transient loss of consciousness. A brain computed tomography showed no remarkable findings. A subsequent computed tomography scan for comprehensive evaluation revealed DeBakey type II acute aortic dissection as evidenced by contrast-enhanced imaging. An intimal tear was found on the ascending aorta distant from the proximal edge of a stent graft. Due to the urgency of the situation, the patient underwent emergent ascending aortic replacement. Following the successful intervention, the patient was transferred to a specialized rehabilitation facility with the goal of facilitating further improvement in their condition.
