Hypothermia is used for open heart surgery generally. However, especially deep hypothermia while the circulation is stopped may be involved with aortic surgery. When the entire ascending aorta is removed, it requires this, called deep hypothermic circulatory arrest - sometimes also called total circulatory arrest. When the arch requires surgery, it is a must.
Surgery on the aortic arch was one of the last aortic challenges to be addressed - the problem has to do with how to protect the brain while working on the source of its blood supply. In 1975, Dr. Randall Griepp published his results for aortic arch surgery in 4 patients - 3 of them lived, and it was the beginning of hope! He and his group in NY have continued to work on and perfect this, and are recognized through out the world for expertise in this area.
This past week there was an aortic disease symposium held at Yale. The meeting was dedicated to the memory of John Ritter. Dr. Griepp gave the special lecture on hypothermia in aortic surgery. Here is a link to the agenda for the meeting.

My husband had 23 minutes of deep hypothermic circulatory arrest. He had absolutely no problems from it - I personally think it is easier on the brain to be colder,
but only if it is done properly. There are only a few, assuming that I have a choice, that I would allow to touch my aorta, and particularly the arch.
When I understood that my husband had had deep hypothermia and circulatory arrest, at first it sounded terrible to me. Now I realize that it was the very best thing for him, because he was very fortunate to have it done by someone expert in it.
