Can Radiation Therapy Lead To Carotid Artery Blockage
I do not agree: Radiation to the head and neck area could potentially increase the risk for carotid artery disease years after the treatment. I routinely discuss this risk with my patients whom are being treated for a head and neck cancer. Unfortunately, the treatment with radiation is necessary for their disease so the risk of treatment is outweighed by the benfits. ...Read moreSee 2 more doctor answers
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

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
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
Would an echocardiogram and stress test show if there was a blockage or problem in the carotid arteries?
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 moreSee 2 more doctor answers
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 moreSee 3 more doctor answers
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 moreSee 2 more doctor answers
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 moreSee 2 more doctor answers
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 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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
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
I got a CT scan and a sonogram a year ago for my arteries to heart and carotid arteries; both of them came clear. Could arteries have blockage one year later?
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
