The treatment of complex aortic arch disease continues to be among the most demanding cardiovascular operations, with a considerable risk of death and stroke. Since January 1990, our single-practice service has performed over 3000 repairs of the aortic arch. Our aim was to describe the progression of our technical approach to open aortic arch repair. Our center’s surgical technique has evolved considerably over the last three decades. When it comes to initial arterial cannulation, we have shifted away from femoral artery cannulation to innominate and axillary artery cannulation. During difficult repairs, this transition has made it easier to use antegrade cerebral perfusion rather than retrograde cerebral perfusion, which was commonly used in the early days. Brain protection tactics during open aortic arch procedures have evolved from profound (≤14 °C) hypothermia during circulatory arrest to moderate (22-24 °C) hypothermia. Aortic arch repair is performed through a median sternotomy and may treat acute aortic dissection, chronic aortic dissection, or degenerative aneurysm. Reoperative repair - that necessitating redo sternotomy - is common in patients undergoing aortic arch repair. The majority of repairs will include varying portions of the ascending aorta and may involve the aortic valve or the aortic root. In some patients, repair may extend into the proximal descending thoracic aorta; this includes elephant trunk, frozen elephant trunk, and antegrade hybrid approaches.
