Cerebral Protection in Aortic Arch Surgery: Hypothermia Alone Suffices
Aneurysms of the aortic arch are among the most challenging cases for surgical treatment and require procedural expertise for their safe conduct. Up to now, 3 main strategies for cerebral protection of patients undergoing extensive aortic surgery have been developed and studied. These are straight deep hypothermic circulatory arrest (DHCA), retrograde cerebral perfusion (RCP), and ante grade cerebral perfusion (ACP).
