Outcomes after aortic arch reconstruction for infants: deep hypothermic circulatory arrest versus moderate hypothermia with selective antegrade cerebral perfusion.

Objectives: Optimal cerebral and visceral protection is crucial in aortic arch surgery. The main method for this protection has traditionally been deep hypothermic circulatory arrest (DHCA). Recently, antegrade cerebral perfusion with moderate hypothermia has become the preferred strategy for adult patients and some children undergoing aortic arch surgery.
