Carotid artery stenosis is how common at which age groups?

Carotid artery stenosis is how common at which age groups?

Above 50: There is different numbers depending on age (more common above 50), sex (more common in males), presence of symptoms and severity of stenosis. Generally incidence of asymptomatic more than 50% stenosis in people above 50 years of age is around 6-11% in men and 5-7% in women. ...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 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

Could you explain what is carotid artery stenosis and stroke?

Narrowing: Carotid stenosis means narrowing of the carotid artery. This can cause decreased blood flow to the brain and result in a stroke. Plaque build up at the site of narrowing can also cause plaque pieces flow up to the brain and cause stroke. ...Read more

Do you know the data sheet for examination of a patient of carotid artery stenosis?

Variable: Carotid evaluations can be done with physical exam, ultrasound (doppler) and ct, mra and angiography in properly selected patients.
The dat-results are presented in variable formats but leading to degree of narrowing (stenosis) or irregularity (ulceration). ...Read more

Could you know the data sheet for examination of a patient of carotid artery stenosis?

Unclear: I'm not clear what you're asking? If carotid stenosis is suspected, the neck is auscultated for bruits. The pt is queried for neurologic deficit and, if appropriate, a neurologic exam is done. Duplex ultrasound exam of the neck is done. If necessary, a ct, mra, or angiogram may be necessary in selected cases. ...Read more

Who gets carotid artery stenosis?

Who gets carotid artery stenosis?

Elderly Hypertensive: Carotid stenosis usually occurs secondary to longstanding atherosclerosis. Risk factors include high blood pressure, diabetes, and coronary artery disease. It takes time for atherosclerotic plaques to develop, so most patients with carotid artery stenosis are older adults. ...Read more

Are there meds for carotid artery stenosis?

Yes: Patient with carotid stenosis should be on anti platelet medicine like Aspirin or Plavix, also if tolerated, must be on a statin (cholesterol lowering medicine) like Lipitor (atorvastatin) to stabilize atherosclerotic plaque and prevent its progression to worse stenosis. In cases of symptomatic carotid stenosis above 50% then surgery is better than just medical treatment. ...Read more

What is the definition or description of: carotid artery stenosis?

What is the definition or description of: carotid artery stenosis?

Artery blockage: Carotid artery stenosis means that the carotid arteries have blockage, usually in the form of atherosclerosis. This can cause stroke. The more severe the blockage, the greater the risk
in the absence of neurological symptoms, most cases can be handled with medicine and close periodic follow up by a vascular surgeon. However, if the blockage is more than 80%, surgery will reduce the stroke risk. ...Read more

Could you lose function to certain parts of the body if nerves around a internal or external carotid artery were cut?

Could you lose function to certain parts of the body if nerves around a internal or external carotid artery were cut?

Yes: There are two main nerves that are in the area of the carotid artery. Above the bifurcation of the Internal and external carotid is the hypglossal which controls the toungue. If cut, the toungue will deviate to the side of the injury.
The other main nerve is the vagus. It is located between the common carotid and int jugular, if cut would be disasterous ...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 could cause peak systolic velocity of right internal carotid artery to be elevated to 130cm/s but no elevation in left ica & no stenosis found?

Peak velocity: Sometimes what is being recorded is not the velocity in the internal carotid but an adjacent artery such as external carotid. This could also be related to high flow situations or other technical factors. ...Read more

I have less than 50% stenosis of the bilateral internal carotid arteries by nascet criteria, should I be concerned?

Generally no: This is mild/moderate blockage and rarely associated with symptoms. Treatment is usually Aspirin and a statin. Do not smoke! Follow up with carotid ultrasound every few years. ...Read more

Hi doctors, can you tell me what is stenosis of the carotid artery?

Narrowing: "stenosis" means narrowing. Most commonly stenosis of the carotid artery is from atherosclerotic disease, or hardening and buildup of plaque within the artery itself. Atherosclerotic disease of the carotid artery is implicated in stroke and is best monitored by a vascular surgeon, who can easily follow the degree of narrowing by ultrasound on a periodic basis. ...Read more

What does it mean when you have 1-15% stenosis of right and left internal carotid artery and that clinical correlation recommended?

Mild narrowing: The cutoff for a signicant or abnormal is 50% narrowing or greater. Minor narrowing < 30% is considered normal. Clinical correlation means to ask your doctor what the test means for you as an individual. ...Read more

Bilateral high flow in common carotid artery and internal carotid artery with normal end diastolic velocity and no stenosis. Is this normal?

How high is high?: Increased flow without stenosis can happen if the cardiac output is very high or there is tortuosity if the arteries Generally don't worry until systolic velocity is over 200 cm/sec and even then it is probably ok with normal diastolic velocity why did you get the test? IF you are asymptomtic I would not worry too much ...Read more

Can past vad - vertebral arterty dissection cause stenosis or a bruit in the carotid artery? Or any other stress to local arteries? What is the path?

Not usually: A bad trauma can cause dissection of vertebral and carotid arteries at the same time but rare. Carotid bruit can indicate a stenosis which is usually atherosclerosis. Fibromuscular dysplasia can cause narrowing. Fmd is usually in women. Fmd can affect the vertebral arteries and the carotid arteries. Fmd can cause dissection in vertebral and carotid arteries. ...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

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
