“Is vascular surgery done under regional anesthesia?”

I use a mild oral sedative prior to varicose vein procedures.

There are many different types of vascular surgery. For example if you are having an aortic aneurysm repaired you will probably be under general anesthesia. If you are having a small varicose vein treated you will likely have local anesthesia. Regional anesthesia is often used for AV fistula creation in the arm or orthopedic surgery to fix the knee or hand.
