An octogenarian patient with double thoracic saccular aortic aneurysms in conjunction with a Kommerell diverticulum treated with a staged hybrid repair.

BACKGROUND A Kommerell diverticulum (KD) and aberrant subclavian artery (ASA) are an aortic vascular anomaly. CASE REPORT We describe a case of a KD with a right ASA and two asymptomatic thoracic saccular aortic aneurysms in an 83-year-old man, which were treated with a total arch replacement, frozen elephant trunk technique, and staged thoracic endovascular aortic repair. CONCLUSIONS Some reports on the treatment of a KD and ASA have been reported thus far in the literature. However, it is considered rare to find two asymptomatic thoracic saccular aortic aneurysms coexisting with a KD in a patient over 80 years old, as was discovered in this patient.
