I have a 100% occluded right intercranial internal carotid and a 50% narrowed left intercranial carotid.  At what point is the left a worry?

Symptoms: If you have symptoms of a TIA ("ministroke") or 70% or more narrowing on the left. Meanwhile, the person you're describing should be on aspirin or plavix (clopidogrel) and a statin drug (to lower cholesterol) with optimal blood pressure. ...Read more

What does it mean for me when my carotids are 95% occluded on ultrasound?

95% Blocked: Ultrasound is a great way to determine how blocked the carotid arteries are. It turns out that the more blocked they are the greater the risk for a stroke. Even if you are not having a symptoms (mini-stroke or actual stroke), a blockage of 80% or greater is enough to warrant a carotid endarterectomy. If you are having symptoms, then a blockage of 50% or greater is enough to warrant surgery. ...Read more

I have bilateral carotid artery dissections that are 100% occluded for 1 year. Is it possible they will recanalize after so long?

I have bilateral carotid artery dissections that are 100% occluded for 1 year.  Is it possible they will recanalize after so long?

Yes: But it is unlikely. If you have survived one year with both carotid arteries occluded by dissections you are very lucky. If you have no symptoms you might get away without surgery. Do you have other diseases or any symptoms? ...Read more

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. ...Read more

Are carotid duplexes dangerous?

Are carotid duplexes dangerous?

No: Duplex ultrasound is an excellent, noninvasive method to check for abnormal flow and atherosclerotic plaque buildup in your arteries. They are safe and effective. Occasionally a secondary test such as a ct or MRI will be recommended to confirm findings on an ultrasound. The test is not painful, and involves the technician using jelly on the area to be studied and gentle pressure with a probe. ...Read more

What is a carotid duplex scan?

What is a carotid duplex scan?

Ultrasound study: Carotid duplex is an ultrasound study to evaluate the carotid (and usually the vertebral) arteries (to the brain) for narrowing and blockage. Blood flow is measured using doppler ultrasound to define areas of stenosis (narrowing). It is an outpatient study with no preparation. You just need to lie quietly on a table while the probe is placed against your neck. The exam is totally painless. ...Read more
