Accuracy of carotid artery ultrasound to detect circ problems and impending cva?

Accuracy of carotid artery ultrasound to detect circ problems and impending cva?

Screening test: Ultrasound is a good screening test for carotid stenosis which is a risk factor for a stroke, however the ultrasound even in an accredited lab is not predictive of risk for stroke. Stroke may be ischemic or hemorrhagic and may not be caused by carotid disease. ...Read more

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Do carotid stents cause strokes?

Possible: It is possible to develop a stroke during carotid stent placement (~ 4% in optimal patients). However the carotid stent is effective at preventing further strokes and that is why they are placed. At this point carotid stents are reserved for patients who are at high risk for open carotid endarterectomy (surgery). ...Read more

Will coronary cta with calcium score show possible cause of caroited artery bruit?

Will coronary cta with calcium score show possible cause of caroited artery bruit?

Coronary CTA: Coronary cta looks at the coronary arteries. A carotid artery cta would look at the carotid. The coronary study would not normally include the carotid arteries in its imaging. ...Read more

Can a 3 mm thyroid nodule cause carotid artery occlusion?

Can a 3 mm thyroid nodule cause carotid artery occlusion?

No: That is a very tiny thyroid nodule and would not cause any symptoms and would not be able to be felt by yourself or on an exam. ...Read more

Cerebrovascular Duplex Scan reveals bilateral homogeneous plaque present in carotid bulbs. No evidence stenosis/plaque in ICA. Lower stroke risk?

Carotid duplex: Im glad you have favorable findings but the presence of plaque signifies atherosclerosis and a small risk of stroke that can be lowered by medical intervention;,so discuss this with your provider ...Read more

Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?

Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?

Results: Because these are two different imaging modalities, it is possible to get divergent results. Generally however these two studies show congruent data. ...Read more

What is the accuracy of carotid artery ultrasound to detect heart problems?

What is the accuracy of carotid artery ultrasound to detect heart problems?

Depends: Some studies suggest that by using carotid duplex and measuring intima media thickness we can detect early coronary artery disease with sensitivity of 85% but low specificity of 39% . It is a good screening test that is not invasive but not very accurate. ...Read more

What is carotid artery stenosis and stroke?

What is carotid artery stenosis and stroke?

2 things: Carotid artery stenosis means narrowing of the artery. Stroke is death or damage to brain due to circulatory issues. Many strokes (approx 1/3rd) are due to carotid artery disease. Although frequently connected, they are not the same. Many strokes occur without carotid stenosis. Many carotids are completely occluded (slowly) without resultant strokes. ...Read more

Carotid mra vs carotid doppler ultrasound better predictor?

Carotid mra vs carotid doppler ultrasound better predictor?

Doppler Ultrasound: Ultrasound has proven to be cost-effective and quite accurate in determining the degree of narrowing in the carotid artery. Many vascular surgeons, including myself, solely rely on it to decide whether someone needs an operation. Mra is not so good and over-estimates the actual degree of narrowing. I would not rely on its findings to decide on operating. As mentioned a cta is much better. ...Read more

Can carotid surgery reverse stroke symptoms or not?

Can carotid surgery reverse stroke symptoms or not?

No: Carotid surgery is performed to prevent a major stroke. It does not reverse any brain injury from a previous stroke. In theory it should help with recovery from a stoke by improving circulation. ...Read more

Carotid artery disease, what to believe, if different results from duplex ultrasound vs. Ct angiogram (cta)?

CTA better: Although cta is more accurate but it also depends on image quality done by radiology . If there is two conflicting studies of the carotid artery , then you should get the gold standard conventional arteriography if clinically indicated. ...Read more

Can carotid artery stenosis cause increased brain pressure if left untreated?

No: No. Carotid stenosis is the blockage of blood flow to the brain which significantly increases the risk of stroke. A blockage in the carotid artery would more likely decrease blood flow/pressure in the brain. ...Read more

What is more reliable CT scan or ultrasound of carotid artery?

Ultrasound : Is a good screening exam. Ct angiogram is best to evaluate the carotid arteries. Conventional angiography is good also but does have a small risk of stroke. See radiologyinfo.Org for more info. ...Read more
