Depending on severity of the problem, treatment can be divided into 3 types.
1. If the problem is mild, medication can usually take care of it. Medication usually involves using agents to prevent blood clotting and tablets to lower cholesterol. This will help to delay artery blockage worsening.
2. For more severe problems (more than 70% blockage), surgery to clear out the blood clots directly will be the best scientifically proven option (Carotid Endarterectomy). This also prevent strokes.
3. In certain cases where surgery cannot be performed safely due to general anesthesia risk, hostile neck and poor patient conditions, balloon and stents (angioplasty & stenting) can be done instead using X-ray guidance to improve blood flow to the brain. This remains slightly inferior to surgery with a higher chance of recurrence of the blockage.
