Why do the carotid arteries get blocked?
Health ServicesThe carotid arteries are the major vessels that supply blood to the head, moving up both sides of the neck to the brain and face. When blood flow to the brain is blocked, a serious medical condition called a stroke or brain attack can occur. The narrowing or blockage is often caused by a buildup of blood clots and fatty plaques (like cholesterol) in the fork of the carotid artery where it branches into the vessels that supply blood to the face and brain.
Related QuestionsWhat are the carotid arteries?
Heart CenterThe main supply of blood to the brain is carried by the carotid arteries. The carotid arteries branch off from the aorta (the largest artery in the body) a short distance from the heart, and extend upward through the neck carrying oxygen-rich blood to the brain. There are four carotid arteries: the right and left internal carotid arteries and the right and left external carotid arteries. One pair (external and internal) is located on each side of the neck.
Related QuestionsWhy are the carotid arteries important?
Heart CenterBecause the carotid arteries deliver blood to the brain, carotid artery disease can have serious implications by reducing the flow of oxygen and nutrients to the brain. The brain needs a constant supply of oxygen and nutrients in order to function. Even a brief interruption in blood supply can cause problems. Brain cells begin to die after just a few minutes without blood or oxygen.
Related QuestionsHow do you find out if the carotid artery is blocked?
Health ServicesTwo tests are available to CREST physicians to pinpoint exactly how much narrowing has occurred in your carotid artery: Ultrasound, or carotid Doppler uses sound waves to measure the rate of blood flow through the artery. (You may have already had this test.) Cerebral angiography uses a contrast material injected into an artery (usually in the groin) to make the vessels in the head and neck visible in x-rays. Pictures are then taken and the amount of narrowing is measured.
Related QuestionsHow is the intimal thickening of the carotid arteries measured ?
FAQTake a high resolution (> 7 mHz) ultrasound linear probe and visualize the intima before the carotid bulb for a length of 1.0-2.0 cm. Using the trace function, measure the area of the intima, that is clearly visible. Divide this area by the length of the area to obtain the mean intimal thickness. Perform measurements on both sides. Use the side with the higher value. Store all images and calculations on a back up media.
Related QuestionsHow can you tell if my arteries are blocked?
Advanced Screening, LLCAnswer: Advanced Screening uses some of the most advanced Duplex Ultrasound Imaging Equipment available on the market today. Combined with the skill level of our technologist, the equipment can both image and yield an audible signal of the blood flowing through the arteries. What the technologist visualizes is plaque or grayish-white matter that is clinging to the arterial walls. What the technologist evaluates is the frequency of blood flowing through the arteries.
Related QuestionsWhat other arteries in the abdomen can become blocked?
Several of the main arteries within the abdomen can become narrowed by atherosclerosis. When this affects the arteries to the kidneys, the patient can develop severe hypertension, or high blood pressure, and ultimately kidney failure. Although this problem occurs in less than 10% of people with high blood pressure, it is important to recognize because the patient's high blood pressure can be completely cured, or dramatically improved, by restoring circulation to the kidneys.
Related QuestionsHow might EDTA chelation therapy work to clear blocked arteries?
Questions and Answers: The NIH Trial of EDTA Chelation Thera...Several theories have been suggested by those who recommend this form of treatment. One theory suggests that EDTA chelation might work by directly removing calcium found in fatty plaques that block the arteries, causing the plaques to break up. Another is that the process of chelation may stimulate the release of a hormone that in turn causes calcium to be removed from the plaques or causes a lowering of cholesterol levels.
Related QuestionsCan a calcium scan tell me how blocked my arteries are?
FAQ on EBTA plaque detector or coronary calcium scan will be able to tell you whether you have heart disease. It can detect heart disease at its very early stage, even before any cardiac symptoms are noticeable and even before your stress test indicate any abnormality.
Related QuestionsIs the carotid artery scanned, or simply the arteries around the heart?
AAMC: Ask An AAMC ExpertThe full body scan does include the cardiac scan as well as the carotid arteries in the neck. The full body includes the head, neck, chest, abdomen, pelvis, heart, lungs and spine. It will, therefore, detect any plaquing or calcifications in the carotid arteries in the neck as well as the iliac arteries in the groin area.

Cardio Health Intervention Procedures for... - Hair Loss Adv...The standard choices are the veins in the legs and the mammary arteries in the chest. Studies have shown that the mammary artery lasts considerably longer than the best leg (saphenous) veins. Overall, the veins used as bypass arteries will last approximately 5 to 10 years; the mammary arteries, 10 years or more.
Related QuestionsWhat is carotid artery disease?
NewswiseCarotid artery disease occurs when plaque builds up on the artery wall. This condition is called stenosis and is the leading cause of thrombolotic stroke. Early warning signs of stenosis can be detected by a primary care physician during a regular physical exam and include the presence of a carotid bruit or a difference in blood pressure in the right and left arms.
Related QuestionsCan a drink or two each day help my arteries?
LifeHeart.comNew studies hint that modest alcohol drinking may slow artery stiffening that happens with age. But doctors aren't yet giving the thumbs-up to drinking for heart health because of the risk of addiction, liver damage, and accidental injury or death. Ask your doctor for advice, and if you decide to drink, limit yourself to no more than one alcoholic drink per day if you're a woman, and no more than two per day if you're a man.

Related QuestionsHow is the amount of calcium in my coronary arteries determined?
FAQ'sThis involves a simple CT scan of your heart connected to an EKG device. No injection is needed and the examination takes minutes. After the study is complete, the data is transferred to a sophisticated computer workstation, there the location and amount of calcium in your coronary vessels is determined. Finally, you are assigned a score which reflects the amount of calcification present; the higher the score the more calcium detected.

DenyHosts Frequently Asked QuestionsIf your versions and configuration of sshd and tcp_wrappers sometimes/always log hostnames rather than IP addresses then you can have DenyHosts attempt to resolve each IP address in the allowed-hosts file in order to determine the corresponding hostname. In doing so, any host that matches either this resolved IP address or the hostname will not be blocked. Note: Depending on the number of entries in your allowed-hosts file, this operation can be network intensive but only at DenyHosts startup.

Related QuestionsHow does endovascular stenting differ from a carotid endarterectomy?
NewswiseA carotid endarterectomy is a surgical procedure in which the carotid artery is exposed and plaque is removed, thereby reducing the risk of a thrombus breaking off and interrupting blood flow to the brain. Patients are often hospitalized for 48 hours after the procedure. Complication rates for carotid endarterectomy are approximately 3 percent.
Related QuestionsWhat is Carotid Stenting?
Dr. Fayaz ShawlCarotid Stenting basically involves the same technique as for coronary angioplasty. Initially, we dilate the lesion with balloon angioplasty and then place a stent across the blockage. The whole procedure takes only half an hour to 45 minutes and the risks are considerably less than carotid surgery, even though carotid stenting is just evolving. Further refinement in equipment and technique greatly reduces the risks.

Frequently Asked QuestionsYes. Reclosure (restenosis) is also a problem with the stent procedure. In recent years doctors have used new types of stents called drug-eluting stents. These are coated with drugs that are slowly released and help keep the blood vessel from reclosing. These new stents have shown some promise for improving the long-term success of this procedure.
