I have 69% blockage in the left carotid artery. I also have dizzy fainting spells. What should I do?

I have 69% blockage in the left carotid artery. I also have dizzy fainting spells. What should I do?

Be evaluated: A 69% carotid artery blockage on one side isn't enough to cause dizziness/ fainting spells. Is it low blood pressure, anemia, a middle ear problem? It's best to have your internist work through the possible causes. With regard to your cerebral circulation, it would be helpful to know how your vertebral arteries look. A simple ultrasound can evaluate these arteries which supply the balance center. ...Read more

Artery (Definition)

Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

What is the cause of dilated carotid artery and dizziness?

What is the cause of dilated carotid artery and dizziness?

Unknown: Causes for carotid ectasia or aneurysms are not known. There are so many causes of dizziness. You need work-up. It is difficult to enumerate in this limited space. ...Read more

I have been troubled by ongoing vertigo, and I also have very high cholesterol, is it possible for blocked carotid arteries to cause dizziness?

I have been troubled by ongoing vertigo, and I also have very high cholesterol, is it possible for blocked carotid arteries to cause dizziness?

Not usually: If you have carotid occlusive disease (carotid stenosis) it can increase risk of mini-strokes (tias) and stroke but not general just vertigo. ...Read more

Slight equilibrium issue - not real dizziness, never fainted, not really light headed either. 32 yrs old, no known fam his, non smoker, slightly overweight, could it be carotid artery/heart issue?

Slight equilibrium issue - not real dizziness, never fainted, not really light headed either. 32 yrs old, no known fam his, non smoker, slightly overweight, could it be carotid artery/heart issue?

Ear first: Would get checked out by ENT physician first at that's more likely the cause. At your age a cardiac issue would likely be some type of atrial arrythmia often related to excess stimulants like caffeine or lack of sleep. If ears negative then consider visit to cardiologist. ...Read more

Is a moderate to severe blockage in left carotid artery dangerous?

Is a moderate to severe blockage in left carotid artery dangerous?

Carotid blockage: If asymptomatic with use of proper medical therapy a moderate carotid blockage is fairly low risk. Many vascular surgeons would favor no intervention in this situation. If symptomatic, would recommend repair of this. Options include stenting or open surgery, carotid endarterectomy. Best data suggests that stenting over age 65 -70 has higher risk of stroke than endarterectomy. ...Read more

How do you establish cause and effect in Carotid Artery blockage stroke.?

How do you establish cause and effect in Carotid Artery blockage stroke.?

Carotid disease: If angiogram was "fine" then you must not have any. The best way is to get a piece of the blockage in the carotid and look at it under a microscope. Most common cause would be vascular damage (rust) from smoking, high blood pressure, high lipids or old trauma. Happy to do 2nd Opinion to help narrow this down in you. ...Read more

What does intimal thickening of the carotid artery mean when thrre is no blockage?

What does intimal thickening of the carotid artery mean when thrre is no blockage?

Somewhat unclear: Blockages in the carotid artery of a certain severity may increase one's risk of stroke. For those carotid arteries without a blockage, some physicians measure the intima (the inner-most lining of the artery) and derive a value called the imt, or intimal-medial thickness. It's supposed to help us determine severity of atherosclerosis, but this is somewhat controversial. ...Read more

I have a carotid artery blockage. If I watch my diet from now on, will the blockage go away?

Unlikely: Diet alone will most likely not make the blockage go away. Medical management with Aspirin or Plavix (clopidogrel) (anti-platelet agents) and cholesterol lowering meds (statins) will give you the best results. ...Read more

How likely would it be that both Carotid arteries <50% Occluded will progress on medication to a higher percent blockage over a year in a female 75+?

How likely would it be that both Carotid arteries <50% Occluded will progress on medication to a higher percent blockage over a year in a female 75+?

Carotid blockage.: It's not the presence or absence of the medication that matters. It's the efficacy of the medication that matters. How well are BP, blood sugar, cholesterol and weight controlled? Are we smoking cigarettes? Blockage will progress if risk factors for progression are not adequately controlled. ...Read more

How reliable is ultra sound for detecting carotid artery blockage?

How reliable is ultra sound for detecting carotid artery blockage?

Excellent: Ultrasound duplex imaging of the cervical carotid arteries is very good at determining significant arterial narrowing. Changes in the flow patterns of the carotid arteries can also suggest disease in the internal carotid arteries further on in at the skull base even though the arteries themselves cannot be seen at that level. ...Read more

I have 70 percent blockage and doctor. Wants to cean. Out my carotid. Artery. And I am. Frightened of stroke I have heard of three people. Who had?

Need Surgery: Acas trial in United States showed benefit of surgery for over 60% stenosis with risk reduction over 5 years. You want to make sure that you see experienced vascular surgeon. If you are a good anesthetic risk you should do fine and be able to go home day after surgery. ...Read more

Grandma has heart disease and mini strokes and a carotid artery blockage. Will she live long?

Grandma has heart disease and mini strokes and a carotid artery blockage. Will she live long?

Life expectancy: Life expectancy is multifactorial and thus with the little information provided, it's impossible to really discuss survival. But if your grandmother has carotid artery blockages and is having mini-strokes, she may be at high risk for an actual stroke if the blockages are not addressed. Please see a board-certified vascular surgeon. ...Read more

If grandma has heart disease and has mini strokes, must we rule out a carotid artery blockage?

If grandma has heart disease and has mini strokes, must we rule out a carotid artery blockage?

Yes: The common causes of stroke are narrowings in the carotid arteries, tiny clots arising from the heart or fragments of plaque from the aorta. Carotid artery blockages can often be treated with stents or with surgery, reducing the risk of major stroke in the ruture. ...Read more

How can a dopplar test and mra on a carotid artery show different results dopplar-no blockage mra-severe stenosis happened to my husband now cta next?

Doppler: Is technician dependent and mra can sometime overestimate the degree of stenosis. Cta is the test of choice for carotids. Angiogram remains the gold standard but not commonly done any more since it is more invasive and does carry a small risk of stroke. ...Read more

I have been occasionally waking up with dim vision in left eye. I have a 60% blockage of my carotid artery on the left. Could this be the cause?

I have been occasionally waking up with dim vision in left eye. I have a 60% blockage of my carotid artery on the left. Could this be the cause?

Maybe: Amaurosis fugax is what you are referring to. The plaque in the carotid artery can shed particulate matter upstream, and when this enters the artery going to the same side eye, typical symptom of "shade coming over the eye" is experienced. Visiting an eye doctor may help make this diagnosis. ...Read more

Husband had eye stroke had dopplar & mta dopplar showed blood flow no blockage mta showed severe stenosis carotid artery how does this happen next cta?

Carotid stenosis: If severe, greater than 60%, then you should consider a potential entarterectomy or even stunting to prevent additional stroke events. Some evidence to suggest also, potential benefit of anti-platelet medication such as Aggrenox and a statin. Discuss with a stroke neurologist, and a vascular surgeon. ...Read more

Have "whooshing" in left ear that has rhythm of heartbeat & Mild vertigo when laying prone. Carotid artery test normal. Could this be inner ear prob?

Whooshing: The carotid may be completely normal and the turbulent flow you're hearing produced nearer to the left ear perhaps inside the skull. It isn't easy to deal with. Seeing you've had trouble with your cervical vertebrae increases chances its related Discuss with your Doc. ...Read more

If I had heart failure and artery blockage would I still be able to get through a workout without angina and pain I am dizzy light headed though?

If I had heart failure and artery blockage would I still be able to get through a workout without angina and pain I am dizzy light headed though?

Yes you could.: You should be under the watchful eye of a good cardiologist who is making recommendations about what is and is not safe exercise for you. Anyone who is 31 with a history of CHF and CAD should be carefully educated about their disease and already know the answer to this question. Follow up with your cardiologist. ...Read more

2 months since biopsy have Headache, dizziness, tachycardias, neck pain after cervical lymph node biopsy, could my carotid artery have been injured.

2 months since biopsy have Headache, dizziness, tachycardias, neck pain after cervical lymph node biopsy, could my carotid artery have been injured.

Not really: Anything is possible but the injury would be unlikely, it would have been readily apparent if it happened at the time of biopsy and your symptoms are not consistent with a carotid eatey injury so I would guess your carotid artery is fine. ...Read more

My throat is hoarse and my left carotid artery hurts and is pounding and I feel like I can't swallow I'm weak dizzy. Could this be tonsils or serious?

My throat is hoarse and my left carotid artery hurts and is pounding and I feel like I can't swallow I'm weak dizzy. Could this be tonsils or serious?

Carotids don't hurt: Well, they probably do....but we don't believe people can know or identify pain in their neck as coming from their carotid artery as opposed to anything else in there. So, if you're having these symptoms you need to get some throat cultures taken, some bloodwork done, & see a doctor about the pounding in your LEFT NECK...sooner rather than later. In other words get seen tomorrow if you can. ...Read more
