Occlusion And Stenosis Of Carotid Artery Without Cerebral Infarction
There is a lot of information linking blood glucose and cerebral infarction and there are a lot of possibilities.
In "PubMed" there are 315 related articles published in the last five years. Too many to read and understand.
Start at Wikipedia and look for "diabetes and cerebral infarction".
May take some reading but will answer your question. ...Read more
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
Cerebral infarction, or stroke, occurs due to suddenly decreased blood supply to part of the brain. This is common when a piece of arterial debris or a blood clot lodges in a small artery.
The risk factors for stroke are smoking, high blood pressure, high blood cholesterol, high blood sugar, and arterial disease. ...Read more
My nephew 11 y old got a cerebral infarction 7 days back with minor signs of speech, v little droop and little difficulty walking. Can he recover 100%?
Can: There is no test than can predict degree of recovery following a stroke (old nomenclature) cerebral infarction (new nomenclature). However the brain is very good at relearning and finding other neurologic tissue to be 'trained'. A child's brain should be more "trainable". Do they know what caused the stroke? ...Read moreSee 1 more doctor answer
What is the probability of stroke with both mitral valve regurgitation and stenosis of carotid artery?
Carotid v. Mitral: The carotid disease if stenosed (>80%) warrants surgical consideration as risk of stroke is increased. The mr, if miderate to severe, poses a risk for congestive heart failure not stroke. If not allergic or have issues with platelet function, daily Aspirin 81mg is recommended for atherosclerosis. ...Read more
Above 50: There is different numbers depending on age (more common above 50), sex (more common in males), presence of symptoms and severity of stenosis. Generally incidence of asymptomatic more than 50% stenosis in people above 50 years of age is around 6-11% in men and 5-7% in women. ...Read moreSee 1 more doctor answer
Unclear: I'm not clear what you're asking? If carotid stenosis is suspected, the neck is auscultated for bruits. The pt is queried for neurologic deficit and, if appropriate, a neurologic exam is done. Duplex ultrasound exam of the neck is done. If necessary, a ct, mra, or angiogram may be necessary in selected cases. ...Read more
Bilateral high flow in common carotid artery and internal carotid artery with normal end diastolic velocity and no stenosis. Is this normal?
How high is high?: Increased flow without stenosis can happen if the cardiac output is very high or there is tortuosity if the arteries Generally don't worry until systolic velocity is over 200 cm/sec and even then it is probably ok with normal diastolic velocity why did you get the test? IF you are asymptomtic I would not worry too much ...Read more
Can past vad - vertebral arterty dissection cause stenosis or a bruit in the carotid artery? Or any other stress to local arteries? What is the path?
Not usually: A bad trauma can cause dissection of vertebral and carotid arteries at the same time but rare. Carotid bruit can indicate a stenosis which is usually atherosclerosis. Fibromuscular dysplasia can cause narrowing. Fmd is usually in women. Fmd can affect the vertebral arteries and the carotid arteries. Fmd can cause dissection in vertebral and carotid arteries. ...Read moreSee 1 more doctor answer
I have less than 50% stenosis of the bilateral internal carotid arteries by nascet criteria, should I be concerned?
Generally no: This is mild/moderate blockage and rarely associated with symptoms. Treatment is usually Aspirin and a statin. Do not smoke! Follow up with carotid ultrasound every few years. ...Read more
Yes: You should be on an Aspirin and a statin. Both lower your risk of a stroke, but neither will make the carotid stenosis go away. ...Read more
Carotid artery stenosis 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 stroke risk. ...Read more
Narrowing: "stenosis" means narrowing. Most commonly stenosis of the carotid artery is from atherosclerotic disease, or hardening and buildup of plaque within the artery itself. Atherosclerotic disease of the carotid artery is implicated in stroke and is best monitored by a vascular surgeon, who can easily follow the degree of narrowing by ultrasound on a periodic basis. ...Read more
Carotid evaluations can be done with physical exam, ultrasound (doppler) and ct, mra and angiography in properly selected patients.
The dat-results are presented in variable formats but leading to degree of narrowing (stenosis) or irregularity (ulceration). ...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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Anything that creates a blockage of the intestinal tract. You may think of the intestinal tract (stomach, small bowel, large bowel) as somewhat akin to a garden hose. If you kink the garden hose, or twist it, or block it inside, you have created an "obstruction". Most obstructions are a results of previous surgery and most of these ...Read more
When the blood supply of a tissue is compromised by whatever mechanism, the tissue will stop working and if blood flow is not restored, the tissue will eventually die ("infarct", both verb and noun). The clinical picture that runs with development of an infarct ("heart attack"; ...Read more
