Elephant trunk reconstruction for aberrant right subclavian and aortic aneurysm.

Although an aberrant right subclavian artery is the most common abnormality of aortic arch development, it is an unusual entity to encounter during repair of thoracic aortic aneurysms. A case of an aberrant right subclavian artery requiring reattachment during repair of an ascending aorta, aortic arch, and descending thoracic aortic aneurysm is reported. We report using the modified elephant trunk technique for surgically managing the aneurysm and aberrant right subclavian artery.
