As with any surgery, there are risks, including the possibility of:
- Complications associated with anesthesia
- Bleeding in the catheter access location
- Stroke / stroke recurrence
- Allergic reaction to chemicals used in the procedure or investigative procedures
Often, the stroke is related to some facet of the patient’s lifestyle or some form of co-morbidity, such as hypertension or diabetes. The carotid angioplasty attempts to correct the symptoms of the condition which brought about the blockage, but does nothing to deal with the underlying reason why the blockage started in the first place.
Because of this, without changes in the patient’s lifestyle or treatment of the co-morbid factor, the blockage is likely to happen again.
Risks can be reduced by following the physician's instructions before and after the procedure.
