Hi madonal1 .....
I flew across the United States to Dr. Friedman for my surgery in 2011. One of my first questions to him before making arrangements to go out there was "What do I do if I experience a complication after returning home?" You should ask him the same thing.
His answer to me was he requires his patients to stay in the LA area for a minimum of 10 days post-op (I stayed 13 days) because the vast majority of complications, if they are to occur, happen within the first few days following surgery. Then, if the very rare instance were to occur with something happening upon returning home, he would put me in touch with a local physician who could give whatever assistance might be needed.
Dr. Friedman is well-known throughout the United States in the AN world, so he has a vast network of contacts.
Thankfully, I had no complications post-op, but I always felt reassured that help would be there if I needed it.
