Multiple options. If the narrowing is significant surgery or a stent are used. Before you get to that point blood pressure control, cholesterol lowering medications and blood sugar control are helpful. And obviously no smoking.
Risk factor control. No smoking. Eat right. Colesterol and blood pressure control. Aspirin if ordered by your doctor. Follow up ultrasounds of the carotid arteries.
Medical or surgical. Agressive medical therapy has been shown to be a better rx than stents or endarterectomy unless there is severe obstruction - greater than 80% - also b mode ultrasound can show whether the plaque is stable (calcified) vs soft. Soft plaque is much more likely to break up and cause stroke. BP control 120/80 or less + aggressive cholesterol rx - I aim for a total cholesterol/hdl ratio of 2.5 or less.
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.
Vascular disease of. Vascular disease of the carotid artery. Perhaps narrowing of the vessel. The disease may lead to a stroke since the brain is not getting adequate blood flow or perhaps a plaque may break off and lodge in a blood vessel in the brain.
Look up. Carotid artery disease on webmd for good info.
It depends. It depends on the severity. Anything along the spectrum of lifestyle changes, to medication, to surgery may be indicated. Speak with your doctor about your particular situation.
See your doctor.. Aspirin often prescribed. Sometimes plavix (clopidogrel) if you are symptomatic. A statin is often needed to control cholesterol and to stabilize the plaque in your neck. Follow up carotid doppler test. Control high blood pressure. Control blood sugar and diabetes. Time to start exercising if ok with your doc. NO smoking please:)
Multiple approaches. Depending on the severity and degree of disease and percent of blockage, a carotid endarectomy may be warranted. However, even with surgery, medical and lifestyle treatments are part of overall treatment plan. Stop smoking, optimize/control your blood pressure, cholesterol, and diabetes are crucial to long term management. Antiplatelet therapy such as aspirin and Plavix (clopidogrel) may be prescribed.
See Vascular Surgeon. Vascular Surgeons are considered "experts" in medical, surgical, & interventional management of carotid artery disease. If the disease is significant (ask you primary doctor), then seek consultation. Medical therapy includes aspirin, statin drug, smoking cessation, low fat diet, & hypertension control. If stenosis is severe then would be considered for surgery or stent of the artery. Ultrasound.
Multiple modalities. Carotid ultrasound is the least invasive of the tests. Mr angiography requires a patient to lie in a confined space. The quality of the images is dependent upon no movement during the study. Ct angiography requires iodine-based contrast dye. Patients with chronic renal disease may have special preparations before their study. The gold standard is most invasive, arterial angiography.
Imaging. There are a variety of non invasive imaging modalities that can be used to identify carotid artery disease. These include ultrasound, MRI and ct techniques. Angiography is often used as a confirmatory test when the above studies suggest narrowing.
See. Carotid disease at www. Sirweb. Org for good info.
Stenosis. Carotid disease is most commonly referred to as a narrowing of the carotid arteries at the bifurcation in the neck. This accumulation of plaque usually occurs in patients with risk factors for peripheral vascular disease such as hypertension, diabetes, hypercholesterolemia and smoking. Plaque is brittle and can cause debris to break off and cause a stroke.
See below. Carotid artery disease means that the carotid arteries have blockage, usually in the form of atherosclerosis. This is diagnosed with a special ultrasound called a carotid duplex scan. 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.
Plaque. Plaque or hardening of the arteries forming in the vessels of your neck. Can lead to stroke.
See below. Carotid artery disease means that the carotid arteries have 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 special instances, carotid angioplasty and stent may be an option.
Hardeningof arteries. Hardening of the arteries may involve carotid arteries. If it progresses it may narrow circulation to the brain or throw off clots to the brain. Symptoms can be transient weakness, numbness, or blindness in one eye or they may be a stroke. If no symptoms, narrowing of the carotid artery of 80% or more means increased risk for stroke and prophylactic surgery may be indicated.
Ultrasound. The first and easiest test is the carotid ultrasound. This will identify if there is any carotid disease. I there is significant disease the most vascular surgeons would recommend either ct angiography or mr angiography.
Duplex ultrasound. First best test is duplex ultrasound. Other test like ct angiogram or mr angiogram could be done. The most invasive but gold standard is conventional arteriography.
Start. With physical exam and carotid ultrasound. Cta or mra may follow. See stroke and carotid disease at www. Sirweb. Org for good info.
Ischemic stroke. Carotid artery disease usually occurs at the origin of the internal carotid artery at the neck and results from plaque build up. The main concern is that blood clots may for from turbulent blood flow this plaque causes, and the clot may travel upward and block an important brain artery, causing a stroke. It is a common found and commonly treated cause for stroke. Several options exist.
Range of findings. A milder form of carotid artery disease is transient ischemic attack, or tia, which can lead to visual symptoms of intetrmittent brown out or darkened vision, called amaurosis fugax. If you have these epeisodes, see your eyemd right away.
Sometimes none. Carotid artery disease often causes no symptoms at all. Sometimes it's detected accidentally, when a sound ("bruit") is heard in the neck, or a doppler is done because of non-specific symptoms such as dizziness. When it does cause symptoms, it's usually a temporary loss of vision in one eye, or a weakness or numbness on one side of the body.
Risk of stroke. Carotid disease is a risk factor for stroke. Prior to a stroke, a patient may have transient ischemic attacks (tias), which are brief episodes of weakness or numbness on one side of the body, coordination or speech difficulties. A specific TIA attributable to carotid disease is a brief loss of vision in one eye called amaurosis fugax. Treatment of asymptomatic carotid disease is controversial.
Tia, visual chsnges. If you develop transient visual disturbance like curtain coming down your eye, tia, it may well be early sign of carotid disease so see your doc soon.
Stroke. Typically has no symptoms but with advance percentage of narrowing will increase risk of stroke or mini stroke.
Carotid Artery. Disease= a number pathologic processes that affect the carotid arteries. In common usage it generally implies atherosclerotic disease.
