Since it is a big surgery and necessary for you because of the aneurysm I would travel if I have to, to get one more opinion if you are confused, or even have the surgery out of town if need be and go to someone who does a lot of these surgeries. Did you ask Dr. Eichler how many of these he does in a year? There are threads and also a list of Doctors in the stickys at the beginning of this forum. Good luck with your treatment and finding a good surgeon.
