ABSTRACT

Prevention of cerebral injury is an important consideration during repair of aortic arch aneurysm, and the major goal of cerebral protection techniques. We describe our surgical strategy for treatment of extended thoracic aortic aneurysms. Between January 2001 and June 2008, 17 men and 6 women, with a mean age of 67.9 ± 8.3 years, underwent total replacement of the arch and descending aorta. Six (26.1%) patients required emergency surgery. A median sternotomy with a left anterolateral thoracotomy provided a good visual field, and bilateral axillary arteries were preferentially used for systemic as well as selective cerebral perfusion. Two (8.7%) patients died in hospital. Prolonged mechanical ventilation was required for 7.3 ± 8.4 days after surgery in 17 patients who all recovered uneventfully. Permanent neurological dysfunction developed in 1 (4.3%) patient who died of sepsis 2 years after the operation. Our results suggest that total arch replacement through a median sternotomy plus a left anterolateral thoracotomy is helpful for extended replacement of the thoracic aorta as well as distal reoperation for dissecting type A aortic aneurysm. Perfusion via bilateral axillary arteries may improve cerebral protection.
