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

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

Can statins unclog carotid arteries?

Not really : Statins stabilize plaque so they are the best defense against atherosclerotic plaque. They decrease ischemic and embolic events. However, they do not reverse a stenosis. ...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

What causes dilated carotid arteries?

What causes dilated carotid arteries?

Sometimes...: A dilated or aneursymal carotid on ultrasound is simply what we call a "redundant" carotid, meaning it is long and wraps on itself, so it looks bigger on ultrasound. True enlarged carotid arteries should be evaluated by a vascular surgeon. ...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

How accurate is carotid artery ultrasound?

Very: Carotid ultrasounds are very accurate. Not only can the plaque morphology be evaluated, but the degree of narrowing can be accurately estimated by measuring the peak systolic velocities. Complete carotid ultrasounds also evaluate the vertebral, subclavian and intracranial arteries. Ct angiograms are often done to confirm ultrasound findings prior to surgery. ...Read more

Can an electrocardiogram detect blocked coronary arteries?

Can an electrocardiogram detect blocked coronary arteries?

Indirectly/Maybe: An electrocardiogram is a recording of a series of heartbeats in a moment in time. Depending on the severity of the blockage, the symptoms being experienced at the time, whether this was an ekg during exercise or stress or symptoms would all come into play as to the ability of the test to detect blockage. Not the best test but of use in the overall evaluation of cad. Get a complete evaluation. ...Read more

If doppler arterial ultrasound says ulnar artery is supplying flow and collateral flow is good . What is embolism with branch occlusion.

I will try again: There are several cause of arterial occlusions. There are degrees of arterial blockage. If a clot moves- embolize s it can obstruct multiple vessels and branches causing more tissue to be under circulated-ischemic. The remaining question is why the radial clotted: embolus, trauma, needle sticks, thoracic outlet and aneurysm. Need exam. Doppler helps define the location but not the cause. ...Read more

What technology can detect blocked coronary arteries?

Cardiac Cath: Still today, the most reliable means of demonstrating "blocked" arteries is cardiac catheterization otherwise known as angiography. Ct scan angiography when done in good hands and experienced centers, is also a reliable test, and if negative, makes it very unlikely that the person has significant disease. ...Read more

When doing doppler of carotid arteries, do u see the arteries up to the level of the cheekbones? can u c everything that u can pulsate with ur hand?

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

C/o Doppler heartbeat sound in left ear worse with turning head but stops when pressing on carotid artery. Ent says ears are perfect?

C/o Doppler heartbeat sound in left ear worse with turning head but stops when pressing on carotid artery. Ent says ears are perfect?

Vascular prob or BP: Your ears ARE perfect - they are hearing the quiet sounds of your heartbeat in the internal carotid artery (next to ear). When you turn your head or press on your neck, you are restricting that flow, hence the changes in the intensity of the sound. The most common cause for this is high blood pressure (BP) or hypertension. Other vascular causes are rare. Get your BP checked & keep a log book of Sx ...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

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

Could you die by touching the carotid arteries?

Exceedingly unlikely: The chances of this happening are extremely remote. Having said that we are always extremely cautious in examining patients with carotid artery atherosclerosis. I have personally witnessed at least one patient getting a stroke after a carotid artery examination--fortunately he recovered. So it is theoretically possible to get a stroke large enough to cause death, but the odds are extremely small. ...Read more

Could the carotid arteries clear themselves or with massaging my neck?

Not likely: A stenosis of the carotid arteries as in any other artery is a process that takes years to develop and is referred to as plaque. Plaque that has developed in the artery does not go away on its own. It can be removed reliably and safely with endarterectomy of the carotid artery. Massaging the carotid arteries will likely not help the situation and may dislodge unstable plaque making it dangerous. ...Read more

Are there any risk of rapture or weakening of the carotid arteries if you press it too hard? How hard do you have to press? It hurts now

Rarely: The carotids are actually a group of three arteries on both sides of your neck. Generally, they don`t weaken or rupture. Rarely, trauma to your neck can cause a rupture or "dissection" of the carotid artery. If you have headache, blurry vision or severe pain see a doctor as soon as possible. ...Read more
