My husband got his physical today and the doc said he has an abdominal aortic aneurysm. The doc didn't like the looks of his EKG and is referring him to a cardiologist and because his feet are always cold (the main artery at the top of his left leg is pretty clogged too) and a vein specialist.

If he needs surgery do they always have to open up the bysmody to fix the aneurysm? How dangerous is this?
