Is it uncommon to have anxiety attacks before surgery?

Common. Anxiety before surgery is to be expected. I suggest methods of relaxation such as meditation, music, exercise, sexual activity (protection), moderate use of alcohol (if ok with surgeon), family/friends support. I also ask patients to remember that objectively speaking, they should be aware that they will be safer during the time of surgery that driving on the freeway. Best wishes.
Anxiety, . Depends on type of surgery, if prepared for it, if have anxiety disorder to begin with, and if expectations of outcome are negative.
