What is the treatment for partially occluded carotid arteries, less than 50%, in a 54 year old female?

Medical management: For most partial occlusions of the carotid arteries of <50%, aggressive medical management is usually all that is needed (i.e. No surgery.) this will include aggressive cholesterol control with LDL < 70 mg/dl and HDL > 45 mg/dl. In addition, blood pressure control with systolic < 130 mmhg and diastolic < 80 mmhg (<130/80). These are general recommendations; see your doctor for your specific case.

ASA 81/D rescan 1 yr: The risk of stroke is not sign. Greater then general pop. However risk of progression is great. Stop smoking. Take statin (regardless of cholestorol level). Have repeat scan every 1-2 years. If you have TIA (mini stroke, transient ischemic attack) you need repeat scan within 3 days and carotid surgery within 2 weeks as risk of major stroke is highest in first 6 weeks after tia.

Observation: As long as there are no symptoms a 50% stenosis of the internal carotid arteries should be followed with an ultrasound every six months. If there are symptoms then the treatment may involve surgery. Please seek the opinion of a vascular surgeon with expertise in carotid disease.
