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

How common is a carotid artery dissection?

How common is a carotid artery dissection?

Uncommon: A dissection is a separation of the inner layer of an artery from the outer layer. The risk aside from direct obstruction is that the internal blood pressure can enter this new pocket and rapidly tear open more of the lining, shutting down the artery or even causing a leak - both of these events are deadly. Any major arteries can be affected; the carotid is less common than the aorta. ...Read more

What is the treatment for carotid artery stenosis?

What is the treatment for  carotid artery stenosis?

See below: Carotid artery disease 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 risk of stroke. ...Read more

What is carotid artery disease?

What is carotid artery disease?

Carotid stenosis: In the carotid arteries the flow of blood goes from being linear to being turbulent due to the "fork in the road" at the bifurcation. This causes the area of the proximal internal and external carotid arteries to develop plaque. This plaque leads to narrowing of the artery. The material that is causing the narrowing is fragile and can break off and cause a stroke. ...Read more

How is a carotid artery stent done?

How is a carotid artery stent done?

Procedure: Performed from a small puncture into the artery in your groin area. A catheter is inserted and is used to evaluate the stenosis. A protection device is then inserted through the blockage and deployed. A suitable stent is inserted and deployed. A balloon opens stent to final diameter. Completion images are taken. Protection device retrieved. Catheters removed. See sirweb.Org. ...Read more

What is renal artery stenosis (ras)?

Narrowed artery(ies): Narrowing of one or both renal arteries that lead from the aorta to the kidneys is called renal artery stenosis. Causes are atherosclerosis or fibromuscular dysplasia (fmd). Fmd is a non-inflammatory, nonatherosclerotic process. Both atherosclerosis and fmd cause hypertension and can lead to kidney failure. Imaging should be done to establish the diagnosis. Kidney specialists usually treat this dx. ...Read more

Is vertebral artery dissection curable?

Is vertebral artery dissection curable?

Generally not: The 2 vertebral arteries arise from the left and right subclavian arteries and supply the brainstem and cerebellum. Dissection is rare (2.5/100, 000), affect women to men 3:1 and can cause stroke in people head trauma, yoga, painting a ceiling. 50% have hbp. Treatment is supportive. Blood thinners are used if bleeding is ruled out. Surgery is not usually an option. ...Read more

How is aortic stenosis treated?

How is aortic stenosis treated?

Surgery vs Meds: Initially aortic stenosis (as) is treated with medications, but when the heart begins failing due to it as well as a few other parameters, it is time to think about surgical valve replacement. This can be done either as a traditional open heart operation or in some cases now percutaneously without having an incision. ...Read more

Is carotid stenosis reversable?

Is carotid stenosis reversable?

Not really : We don't have therapies to "melt plaque", but there are treatments to stabilize atherosclerotic plaque. These include Aspirin and aca inhibitors which can be very effective in treating non symptomatic carotid stenosis. The exception to this rule is if you have a severe stenosis greater than 60 percent the current data supports treatment (endarterectomy v. Stent). ...Read more

Dominant Behavior: The key issue: atherosclerosis, an accumulation of white blood cells in the walls of arteries, typically starts in childhood & primarily driven by lipoproteins (the proteins which transport fat in the water outside cells) is dominant human behavior yet is typically ignored because it remains asymptomatic for decades until plaque rupture releases debris, triggers clots & suddenly blocks blood flow. ...Read more
