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?

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

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

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?

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

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

Was originally told I had a dissection of my internal carotid artery.... Now being told it is a pseudo aneurism..... What exactly is the difference?

Was originally told I had a dissection of my internal carotid artery.... Now being told it is a pseudo aneurism..... What exactly is the difference?

See below: An pseudoaneurysm is when there is a breach in the blood vessel (usually due to injury), but the bleeding gets trapped by the surrounding tissue forming a hematoma. A dissection is actual tearing of the layers of the carotid artery - in this case. In general terms, dissection tends to be more of a surgical issue. In both cases, treatment depends on the size, etiology of the condition. ...Read more

My mri shows hypolastic right vertibal artery and mild irreularity along the bilaeral segment of internal carotid artery?

My mri shows hypolastic right vertibal artery and mild irreularity along the bilaeral segment of internal carotid artery?

Low value finding.: Why? 2 reasons: 1. Spacial resolution of MRI (even more so than CT) is very low compared to the complexity of the anatomic structures named & 2. Arteries are not being visualized, only a contrast agent within the blood inside the artery. Get & study the image data yourself; compare with Netter anatomy illustrations. Irregularity is c/w artery Ds. Good quality echo of carotid walls far better. ...Read more

Left internal carotid artery is difficult to evalution in doppler study. What will be impact on health and what is cure for this.?

Well, . ...: Depending on why you even had the doppler done will answer the question. That simply means anatomically, they may not have seen the carotid well on the study. If you and your Doctor have concerns about the patency of the Artery, then a dye study could be ordered to confirm this since the doppler was inadequate. ...Read more

Internal carotid artery dissection and exercise...My dissection has mostly healed (2mm aneurysm remains) over the last 20 months. What kind of exercise can I do and at what intensity?

Internal carotid artery dissection and exercise...My dissection has mostly healed (2mm aneurysm remains) over the last 20 months. What kind of exercise can I do and at what intensity?

Ask UR cardiologist: Whoever is following you medically needs to be involved in this discussion, as their recommendations is what you'll need to follow closely. Give your doctor a call, and she what s/he says. You don't want to aggrevate the remaining 2 mm aneursym present. This is a great question, and glad you are exercising carefully! ...Read more

Can you you explain peak systolic velocity in right internal carotid artery 61.9 and 80.7 in left internal carotid?

Can you you explain peak systolic velocity in right internal carotid artery 61.9 and 80.7 in left internal carotid?

Sounds normal: These velocities sound normal. As your carotids narrow, the velocity of blood increases. Sort of like when you put your thumb over the end of a hose. The water moves faster and goes farther.

In many labs, the cutoff is 125cm/s. Below this, there may be some narrowing, stenosis, but it is not significant.

Discuss the results with your doctor. ...Read more

What does it mean when an mra shows the intracranial right internal carotid artery is narrowed?

Depends on degree: An mra can show a area of mild to severe narrowing. Usually this means that there is focal atherosclerosis of the vessel.

The consequence of the narrowing depends on how narrow the vessel is, where the vessel is, and if there are alternative routes for blood to use to reach the area of the brain affected by the narrowed blood vessel. ...Read more
