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


This is a part of vascular surgery.
Carotid artery stenosis may lead to cerebral stroke.
----------

Carotid artery stenosis is when plaque forms in the carotid arteries, constricting the flow of blood to the brain. The carotid arteries are the main arteries coming from your heart to your head. The risk is that, if there is plaque, a small piece could break off and get lodged in a smaller vessel in your brain, causing lack of blood to that part of the brain. This can result in in a TIA, or mini stroke, or can even result in something as serious as a brain bleed. An ultrasound is the simplest and safest method for determining plaque, as well as velocity of the blood flow. Velocity at any point of stenosis is a key factor. I could go on about what range velocities should be in, but that opens up a whole worksheet of math problems that I can't begin to explain here.

It would be best to consult your physician if I did not answer your question here, especially as I am not sure what you mean by data sheet. If you are wanting the math equations for velocity, you can e-mail me and I will send you something.  (+ info)

If a person has asymetric brachial blood pressures, this can indicate carotid stenosis on which side?


Is the stenosis on the ipsilateral or contralateral side of the high systolic number?
----------

Carotid stenosis has NO relation to asymmetrical BPs.

It would likely be from either a subclavian artery or an innominate artery stenosis, depending on the side.  (+ info)

are there meds for carotid artery stenosis?


one side is 80% and the other is 60%
----------

TREATMENT
Options for treatment include:

Conservative (antiplatelet drugs)
Carotid endarterectomy (surgical removal of the atheroma)
Carotid stenting  (+ info)

can carotid artery stenosis cause sciatica nerve pain?


i was told that i am experiencing sciatica nerve pain; already diagnosed with blockage of carotid arteries and was told a piece of thrombus may have broken off and subsequently caused pressure on the sciatic nerve. is this possible?
----------

A thrombus breaking off in your carotid artery will travel into your brain and cause a stroke. The sciatic nerve is a large nerve in your buttock region, formed by union of multiple nerves roots originating from the lumbar spine, and under normal physiologic conditions will not be affected in any way by a thrombus in the carotid artery. Sciatic nerve pain is usually caused by a compressive lesion (i.e. a disc herniation in the lumbar spine). In order for a thrombus to go from the carotid artery to the buttocks, it must first flow down your neck (against the flow of blood), into you aorta, and into your pelvis. Even then, it will not compress or cause "pressure" on anything since it will stay lodged inside a branch artery and obstruct it.  (+ info)

what is more accurate, a color carotid Doppler ultrasound or a contrast coratid MRA?


I had both. The ultrasound showed a 40-50% boakage on the right internal carotid and a 20-30% on the left. I then had a contrast MRA of the carotids and it showed nothing. no evidence of stenosis

Which one should I believe, I am getting conflicting answers from different doctors
dopplar ultrasound was done at the doctors office and contrast mra was done at hospital
----------

i believe that generally, the MRA is a more accurate form of imaging compared to doppler ultrasound. that said, both have limitations.

personally i would get the MRA results and go discuss them with your normal Dr and see what his interpretation of the results are.

What is stenosis of the carotid?


A blockage in the carotid artery which is in your neck  (+ info)

Carotid Artery Stenosis question(narrowing of neck artery)?


What is the chance that you do not have a mini stroke before actually having a stroke?
Is it possible to have no symptoms and then just have the stroke out of the blue from it?
----------

Before having a true stroke, you have more risk of getting amourasis fugax, whoch is transient visual loss due to the blocking of the central retinal artery by the thromboembloi fomr carotid stenosis!1


and yes, its quite possible to have no symptoms and suddenly developing a stroke!

but no worries its completely treatable!  (+ info)

grades of stenosis of carotid artery question....?


Can anyone tell me which is a more severe stenosis---grade A, B, C, or D, as determined by ultrasound? I just got back from having an MRA but won`t get results until who knows when. I`m not worried but want to know what I`m dealing with as far as any possible surgery. Thanks.

what is carotid artery stenosis and stroke?


Carotid Artery Stenosis


What is carotid artery stenosis or carotid artery disease?

Carotid artery stenosis is the narrowing of the carotid arteries. These are the main arteries in the neck that supply blood to the brain. Carotid artery stenosis, also called carotid artery disease, is a major risk factor for ischemic stroke. (This is the most common form of stroke and is usually caused by a blood clot plugging an artery.)

The narrowing is usually caused by plaque in a blood vessel. Plaque forms when cholesterol, fat and other substances build up in the inner lining of an artery. This process is called atherosclerosis.

How is carotid artery stenosis diagnosed?

Carotid artery stenosis may or may not cause symptoms. A doctor may hear an abnormal sound called a bruit (BROO'e) when listening to the artery with a stethoscope. The stenosis can be easily detected with an ultrasound probe placed on the side of the neck near the carotid arteries. This is called carotid ultrasonography.

How is carotid artery stenosis treated?

Depending on the degree of stenosis and the patient's overall condition, carotid artery stenosis can usually be treated with surgery. The procedure is called carotid endarterectomy. It removes the plaque that caused the carotid artery to narrow. Carotid endarterectomy has proven to benefit patients with arteries stenosed (narrowed) by 70 percent or more. For people with arteries narrowed less than 50 percent, anti-clotting medicine is usually prescribed to reduce the risk of ischemic stroke. Examples of these drugs are antiplatelet agents and anticoagulants.

Carotid angioplasty may be another treatment option. It uses balloons and/or stents to open a narrowed artery.

Carotid Artery Stenosis and Stroke
What is it?

The carotid arteries are the two large blood vessels at each side of the neck. Stenosis is a narrowing or blockage of a passageway. So, carotid artery stenosis occurs when the carotid arteries become narrow or blocked by carotid artery disease. Carotid artery stenosis is one of the causes of stroke. A stroke occurs when the lack of blood flow and oxygen to the brain results in a sudden loss of brain function.
Who gets it?

The risk of developing carotid artery stenosis increases with high blood pressure, high blood cholesterol levels, high stress levels, diabetes mellitus, diabetes, cigarette smoking, obesity, lack of exercise, and advanced age.
What causes it?

The carotid arteries are the main supply of blood to the brain. The most common cause of blockage in these arteries is atherosclerosis, in which fatty materials collect under the inner lining of the arterial wall.

As the amount of fatty material increases, it forms a thickened area, called plaque, in the artery’s inner lining. This plaque can rupture and cause blood clots, which can break away and travel to the brain, also causing a stroke. Atherosclerosis is also known as hardening of the arteries.
What are the symptoms?

Most people with carotid artery stenosis usually have no symptoms. Some patients may notice a "swishing" noise in either ear with each heartbeat. This sound may occur as blood flows past a blockage in a carotid artery. If symptoms such as partial paralysis, blindness, or feelings of numbness are present, there is great risk of a major stroke. Symptoms of stroke include paralysis of an arm or leg, vision and speech problems, and personality changes. These symptoms can be permanent. Carotid artery stenosis can also cause transient ischemic attacks (TIAs), also called “mini strokes.” With a TIA, small pieces of the fatty materials in the arteries break away and lodge in the small blood vessels leading to the vein. This blocks the blood supply to the brain temporarily and results in symptoms such as blindness in one eye, numbness and tingling of the skin, and weakness of an arm or a leg. TIAs usually last anywhere from 2 to 30 minutes. These symptoms are temporary and reversible, but people who have TIAs are more likely to have a stroke.
How is it diagnosed?

Carotid artery disease is usually detected during a routine physical examination. Your doctor will be able to hear the blood rushing past the blockage in the carotid artery by listening with a stethoscope. An ultrasound test is used to create pictures of the blockage and to measure the amount of blood flowing through the artery. Another frequently used diagnostic test is called a cerebral arteriogram. A special dye is injected into an artery. An x-ray then shows the location and size of the blockage, which are revealed by the path the dye is able to take. If your doctor suspects a stroke, he or she may also order a computed tomography (CT) scan of your head to check brain function. It is important to tell your doctor if you have had any recent episodes of loss of vision or minor paralysis.
What is the treatment?

The treatment for carotid artery stenosis depends upon the degree of blockage and the presence of symptoms. If the carotid artery is less than 70% blocked and you have no symptoms, doctors usually recommend aspirin treatment. One aspirin per day will reduce the likelihood of a blood clot and decrease your chance of stroke. Your treatment will include regular checkups with your doctor to see if your condition changes. If the carotid artery is less than 70% blocked, but you have symptoms, the treatment depends upon the results of the cerebral arteriogram. If this test shows no other problems, patients are usually started on daily aspirin treatment. Again, treatment will include regular checkups for any changes in your condition. However, if the plaque looks rough and irregular, your doctor may recommend surgery to remove the plaque. If the carotid artery is more than a 70% blocked and you have symptoms, the usual treatment is surgery. This procedure, called carotid endarterectomy, involves removing the plaque from the carotid artery. You are placed under general anesthesia and the surgeon makes a small cut (incision) in your neck to expose the artery. He or she then makes a cut in the artery and removes the blockage. The artery is repaired and the incision in your neck is closed with stitches. Following the surgery, you may need to take medicine that makes your blood less likely to clot. There is a one to two percent risk of stroke with this procedure. Another promising procedure is called carotid angioplasty. With this procedure, the area around the carotid artery is numbed with a local anesthetic. Then, a long, thin tube, called a catheter, is passed into the carotid artery in the area of the blockage. The catheter has a balloon on its tip. When the balloon is inflated, it stretches and opens the blocked artery.
Self-care tips

You can help prevent carotid artery stenosis and stroke by following recommendations for preventing atherosclerosis. This means following a diet that is low in fat and cholesterol, exercising regularly, maintaining a healthy weight, and avoiding cigarette smoking.  (+ info)
