Reduction of AEE riskduring intervetions in the aortic arch surgery (Master thesis)

Χριστίδης, Χρήστος/ Christidis, Christos

Aortic arch surgery is a highly complex operation as it requires not only the extracorporeal circulation but also to pause it during the operation, interrupting blood circulation in the area. In order to protect the brain from permanent damage, it is then necessary to use deep hypothermic circulatory arrest (DHCA) at temperatures ranging from 14-20°C in order to reduce cerebral metabolism. There are cases where the use of moderate hypothermic circulatory arrest (MHCA, 20-28°C) in combination with adjunctive cerebral irrigation methods is preferred. The two methods seem generally similar, but comparing individual characteristics and particular conditions of use, it is deduced that more research is needed in order to draw safe conclusions.
