Angioplasty is a conservative, non-surgical procedure, so has relatively minimal risk. The risks associated with angioplasty are much lower than open surgery. Patients usually do not need to stay in the hospital to have the angioplasty procedure because they are not put under general anesthesia. This minimizes costs and risks. Angioplasty is performed through a tiny incision that does not pose much risk of scarring. Patients can resume their normal activities within a few days to a week after their procedure.
