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

How much artery blockage causes pvd pain?

How much artery blockage causes pvd pain?

Everyone's different: The pain of pad is from tissue (muscles, skin, nerves, etc) not getting enough blood. An elite athlete might have symptoms from a single 50% plaque. A sedentary person might not notice a complete blockage or multiple partial blockages. Rest pain is usually from severe plaques at multiple levels. In general, the body compensates for artery plaques for a long time before pain occurs.

Should i be concerned 85-90% blockage in their neck artery?

Should i be concerned 85-90% blockage in their neck artery?

Vascular surgeon: That's a high grade blockage and puts one at high risk for a stroke. A vascular surgeon is best qualified to follow, treat and advise a patient with such a high grade blockage.

With a progressive: Lesion the patient would likely experience chest pain or shortness of breath with exertion.

What could cause an otherwise healthy 27 year old male to have 100% blockage in the LAD artery?

What could cause an otherwise healthy 27 year old male to have 100% blockage in the LAD artery?

Hereditary disease: Without more information, it's difficult to answer the question, but there are hereditary diseases where the blood lipid is elevated high enough to cause early athersclerosis.

I had a cta. Angiogram with contrast. Does that also get images of the coroided arteries typically? If i'd of had a blockage would it have showed up?

The carotids are: Not studied with ct angiography of the brain. The first test if concerns in the carotid arteries is usually a ultrasound with doppler to study the flow in the vessels.

How serious is a circumflex artery blockage that is 90%? Would this likely be fatal and if so, how long before one would have that result on average?

Coronary artery : High grade circumflex disease coul be the cause of angina or infarction. It could be fatal but less likely than lad disease. If well treated you could live a long time with that disease and something else could get you. Smoke and don't work on your condition and chances in infarction are excellent.

What does it mean to have 25-50% blockage in an artery?

What does it mean to have 25-50% blockage in an artery?

Risk: If an artery is 25-50% narrowed, you would generally not have any symptoms except under extreme exercise. However, the fact that it is partially blocked implies that you are at risk for progression - either gradual due the risk factors that cause the partial narrowing or suddenly when platelets stick to the area and cause complete blockage.

If a 70-year-old suffered an artery blockage, what is their chance of survival?

If a 70-year-old suffered an artery blockage, what is their chance of survival?

Depends . . .: Where is blockage? In other words, which artery is blocked? Heart? Brain? Legs? Lungs? Penis? Arterial blockage in heart could cause angina (chest pain) or even heart attack if abrupt. In brain, we call this a stroke. In legs, it's peripheral arterial/vascular disease. In lungs, it's pulmonary embolism (very dangerous & deadly). In penis, it's erectile dysfunction. Chance of survival varies . . .

How do I have all the other arteries check to see if any plaque is building up or blockage?

How do I have all the other arteries check to see if any plaque is building up or blockage?

Various modalities: There are non-invasive tests to look for blockages such as stress echocardiography (stress test w/ultrasound imaging), nuclear myocardial perfusion imaging (nuclear medicine imaging), cardiac ct and MRI (mri is still investigational for coronary anatomy). Gold standard examination requires invasive cardiac catheterization with dye injected into the arteries (or ultrasound) and imaged.

Could it happen that a fall causes a plaque build up in an artery to break off and cause a complete blockage?

Could it happen that a fall causes a plaque build up in an artery to break off and cause a complete blockage?

No: A mechanical fall does not cause arterial plaque to rupture and cause an embolism. However, if someone experienced an embolism to the brain, lung, or leg it could cause a sudden loss of strength and that could cause a fall.

Hi doctors, how long does plaque in the arteries take to progress into a complete blockage, when minimal now. 60 y/o male?

Many factors affect: This is highly variable. The natural course is for it to slowly progress but the odds are it will never progress to complete blockage and it could stay stable or even regress and disappear. Many factors determine how quickly it progresses or regresses: your blood pressure, diet, activity level, stress, exposure to toxins, genetics etc. See http://tinyurl.com/axtab4d and http://tinyurl.com/9x3n594

Does blockage in arteries of retina cause vision loss?

Does blockage in arteries of retina cause vision loss?

See a retina special: Yes. Lack of blood flow due to a retinal artery occlusion can cause severe loss of vision from damage to the retina. A central retinal artery occlusion is worse than a branch retinal artery occlusion. There are no good treatments, but a systemic workup looking for an embolic source is required (carotid ultrasound, echocardiogram). A rarer cause is giant cell arteritis.

I was told I have 100% blockage in my celiac artery. Should I worry?

I was told I have 100% blockage in my celiac artery. Should I worry?

Not necessarily. : Chronic mesenteric ischemia is a condition where the "guts" do not have enough circulation in order to digest food properly. This causes pain after eating and can lead to weight loss. It can be a very serious condition that can require a procedure or surgery. However, the body is amazingly redundant. Most people have to experience complete or near complete blockage in two of the three main arteries to experience these symptoms.

What does intimal thickening of the carotid artery mean when thrre is no blockage?

What does intimal thickening of the carotid artery mean when thrre is no blockage?

Somewhat unclear: Blockages in the carotid artery of a certain severity may increase one's risk of stroke. For those carotid arteries without a blockage, some physicians measure the intima (the inner-most lining of the artery) and derive a value called the imt, or intimal-medial thickness. It's supposed to help us determine severity of atherosclerosis, but this is somewhat controversial.

I have a carotid artery blockage. If I watch my diet from now on, will the blockage go away?

Unlikely: Diet alone will most likely not make the blockage go away. Medical management with Aspirin or Plavix (clopidogrel) (anti-platelet agents) and cholesterol lowering meds (statins) will give you the best results.

My friend's kidneys are affected 85% due to an artery blockage. Is there an operation to fix this?

Yes: The most common way to address blockages in the arteries to the kidneys is with stents. The procedure is straight forward and done as an outpatient. The harder question is, "does he need it fixed?" if his blood pressure is really difficult to control or his kidney function has been worsening, than he would most likely benefit from treatment. Otherwise, the need for treatment is questionable.

What do you suggest if my dad age 62 is diabetic patient and is suffering from 80% artery blockage.?

What do you suggest if my dad age 62 is diabetic patient and is suffering from 80% artery blockage.?

Atherosclerosis: Hi. Your Dad first of all needs treatment for the 80% artery blockage (stent, bypass, or medical treatment depending on the lesion - his doc will recommend appropriate therapy). He also needs really good diabetes, blood pressure, & cholesterol control. He needs to never smoke. He needs good anti-platelet therapy (aspirin, clopidogrel, etc). Good luck to him.
