Very good question. Unfortunately, there are very limited choices for high levels of cholesterol deposits because of the increasing level of risk with the passage of time. Bypass surgery is a major invasive surgery technique. Angioplasty is another surgical technique, which is minimally invasive. However, these techniques do not solve the underlying problem.
Other techniques (non-surgical) include diet and dietary supplements, and/or the use of statins, which aim to prevent or reduce cholesterol deposits; and are better as preventive approaches.
