Abstract
ACUTE TYPE A aortic dissection is a surgical emergency.1 Integrated perioperative management is associated with improved clinical outcome, despite aortic arch repair with deep hypothermic circulatory arrest (DHCA).2,3 Femoral arterial cannulation is safe for all phases of operative repair (before aortic arch repair; after aortic arch repair), with a 2.5% incidence of malperfusion events.4 Although the femoral artery is the authors’ standard site for arterial cannulation in this setting, a case of acute type A dissection in a severely atheromatous aorta is reported that prompted a search for an alternative arterial cannulation site because of concerns about cerebral atheroembolization.
