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

Is surgery for blocked carotid artery dangerous?

Is surgery for blocked carotid artery dangerous?

Carotid surgery: Carotid surgery should be done when risk of not doing so higher. Stroke risk lowest for asymptomatic stenosis, higher in those with TIAs and yet higher with prior stroke. Risk of MI can be higher than stroke risk. Slight risk of bleeding, real but low risk cranial nerve injury, low risk of surgically significant carotid renarrowing. Generally stroke risk lower for surgery, MI risk lower for stent. ...Read more

Can my artery reclog after carotid endarterectomy?

Yes: The recurrence rates after endarterectomy depend in a number of factors such as smoking, patch use for angioplasty and on going problems with managing the risk factors of peripheral vascular disease. Women may also be more likely to have recurrent disease. ...Read more

MRI vertebrobasilar hypoplasia right side theres robust flow void anastomosing the basilar artery w cavernous portion of internal carotid artery/mean?

Normal variant: The arteries at the base of the brain can course in several different patterns but ultimately get the job done, that is, supply brain tissue. Your pattern is like your fingerprint. Some more unusual patterns have an increased association with aneurysms, but this would have likely been described if present and vertebro basilar hypoplasia, as in the picture, is pretty common. ...Read more

Depends: When blood flow is sufficiently reduced by a greater than 70% blockage of an artery or arteries, to the point of permanent damage or weaknening of the heart muscle, or when a plaque ruptures and a blood clot repeatedly forms with resulting blockage of blood flow, then an artery needs to be stented, or bypassed. ...Read more

Could echos sometimes detect artery malfunctions or blocked arteries?

Yes: By echo I am assuming you are talking about an ultrasound. If that is true, the ultrasound machine is more than capable of detecting occluded vessels (arteries or veins) by an experienced ultrasound technician. The ultrasound is a very valuable tool used by vascular surgeons to help diagnosis disease processes. ...Read more

I had parotid surgeries 25 & 20 years ago. I recently experienced TIA. Tests show left carotid artery 30% blocked & right carotid artery 70%. ?

Focus on carotids: Likely the carotid blockages are due to longstanding deposits of cholesterol and plaques along the inside of the arteries. Coukd be due to high cholesterol or genetics. This is likely what's causing your TIAs as these arteries are the main source if blood into the brain. The lack of blood to the brain can cause TIAs and eventually full strokes. Discuss your options with your doc for treatment ...Read more

Can carotid arteries be replaced if they are too blocked for carotid end-arterectomy?

No: If you have a complete blockage of the carotid artery, then no treatment is advised. If blockage is severe, carotid endarterectomy or stenting can be done. The degree of blockage and presence of symptoms determine the need for intervention. ...Read more

What are the treatment options for blocked carotid arteries?

Just depends: There are a lot of options when discussing carotid artery disease. The treatment guidelines are very strict and are based on symptoms and the degree of narrowing found on tests. The options range from observation to placing a stent or surgery to remove the blockage. It is really hard to tell which one is the right treatment until evaluated by a vascular surgeon. ...Read more

My grandfather had a stroke. His carotid arteries are 100% and 85% blocked. What kind of surgery does he need?

Depends: We do not perform surgeries to open up complete (100%) blockages. For the side with 85% blockage he should first and foremost be on an Aspirin as well as a cholesterol lowering statin medication for optimal medical management. The surgical options are an open carotid endarterectomy or a carotid stent. If he can tolerate anesthesia then an open procedure is preferred. ...Read more

My cardiologist told me both of my carotid arteries are blocked. What are my options?

My cardiologist told me both of my carotid arteries are blocked. What are my options?

See vascular surgeon: I suspect he means that the carotid arteries have partial blockage, usually in the form of atherosclerosis. 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. In very special instances, carotid angioplasty and stent may be an option. ...Read more

Carotid artery feels numb and full. I'm only 18 but could it be possible my artery is blocked?

Doubtful: Unlikely, at your age, you would experience carotid thrombosis, unless you had trauma, and then, a stroke would develop. The sensation over the neck could represent muscle spasm, enlarged lymph node, or aberrant thyroid tissue. See your doc, get examined, and hopefully, get reassured. ...Read more

My father is 80 years old and one of his carotid arteries is 90% blocked - is he a good candidate for surgery or not?

Possibly: It depends on his general health especially the condition of his heart and lungs. The surgeon must report no more than a 3 - 5% complication rate. He may be a candidate for a stenting procedure if he has heart problems or multiple strokes. ...Read more

If your mother has 50% blocked Carotid
Arteries at 75+ At what age should the Son or Daughter be checked (Screened)Are there symptoms to look out for?

Atherosclerosis : Atherosclerosis is a systemic problem, I.e. High circulating levels of bad cholesterol (LDL) deposit in different vascular beds over time. In other words, more important for u to get a fasting lipid panel and treat your cholesterol aggressively rather than query about a point in time to check for occult carotid artery disease. Additionally if u are of south Asian descent, pls not LDL <100 mg/dl. ...Read more
