Can radiation therapy lead to carotid artery blockage?

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 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

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?

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

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
