Key result
Partial aortic arch replacement without hypothermic circulatory arrest shows potential to prevent ischemia in one case.
Why the study?
Hypothermic circulatory arrest during aortic arch surgery carries a high risk of visceral organ and lower limb ischemia, and reducing its duration may prevent ischemic complications.
Partial aortic arch replacement without hypothermic circulatory arrest is feasible and may help prevent ischemic complications associated with circulatory arrest.
May support feasibility without hypothermic arrest in select cases; hypothesis-generating and should not yet change practice.
Hypothermic circulatory arrest is commonly used during aortic arch surgery. However, it is associated with high risk of visceral organ and lower limb ischemia. There may be advantages to reduction duration of hypothermic circulatory arrest to prevent ischemic complications. We present a case of partial aortic arch replacement without use of hypothermic circulatory arrest.
