Stroke Secondary To Carotid Stenosis - Health Centers Stroke secondary to carotid stenosis is a group of brain disorders involving loss of brain function. Carotid stenosis means hardening of the neck arteries. Surgery to remove the plaque from the carotid (neck) arteries may be needed, especially if?more than 70% of the carotid artery is blocked. www.channel3000.com /encyclopedia/6860685/detail.html   (499 words)

Carotid Artery Stenosis and Stroke Stenosis is a narrowing or blockage of a passageway. Carotid artery stenosis is one of the causes of stroke. Carotid artery stenosis can also cause transient ischemic attacks (TIAs), also called “mini strokes.” With a TIA, small pieces of the fatty materials in the arteries break away and lodge in the small blood vessels leading to the vein. www.hmc.psu.edu /healthinfo/c/cartoidartery.htm   (919 words)

Johns Hopkins Cerebrovascular Neurosurgery - Carotid Stenosis Carotid stenosis is the narrowing of the carotid artery in the neck. Currently, we can diagnose carotid stenosis by one of three tests: (1) Duplex sonogram of the neck, (2) MRI and MRA scan of the neck, or (3) angiogram or arteriogram of the carotid arteries. During microsurgical carotid endarterectomy, we remove the plaque from the inside of the carotid artery and re-establish uninterrupted flow to the brain. www.neuro.jhmi.edu /cerebro/cs.html   (413 words)

eMedicine - Carotid Artery, Stenosis : Article by Lennard A Nadalo, MD   (Site not responding. Last check: 2007-10-18) Embolization to the anterior cerebral artery or critical stenosis of carotid artery may affect the major branches of the anterior cerebral artery (medial striate artery, recurrent artery of Heubner, orbitofrontal artery, frontopolar artery, anterior internal frontal artery, middle internal frontal artery, posterior internal frontal artery, callosomarginal artery, pericallosal artery, and parieto-occipital artery). Stenosis of the proximal origin of the CCA or the innominate artery may result in clinical cerebral ischemia and must be differentiated from carotid stenosis because the surgical approach is entirely different. High-grade stenosis of the proximal carotid artery may occur in the absence of calcifications, and dense carotid calcification may be seen in the absence of a high-grade carotid stenosis. www.emedicine.com /radio/topic133.htm   (9017 words)

Clinical Alert: Clinical Advisory on Carotid Endarterectomy for Patients WithAsymptomatic Internal Carotid Artery ... The investigators of the Asymptomatic Carotid Atherosclerosis Study (ACAS) are reporting the interim results of a randomized controlled clinical trial of carotid endarterectomy in patients who have asymptomatic carotid stenosis of greater than 60 percent reduction in diameter. Carotid endarterectomy is beneficial with a statistically significant absolute reduction of 5.8 percent in the risk of the primary end point of stroke within 5 years and a relative risk reduction of 55 percent. Carotid endarterectomy, performed in medical centers with documented combined perioperative morbidity and mortality for asymptomatic endarterectomy of less than 3 percent, and on carefully selected patients who continue to have aggressive modifiable risk factor management is beneficial for patients who meet eligibility criteria of asymptomatic carotid stenosis exceeding 60 percent diameter reduction confirmed by arteriography. www.nlm.nih.gov /databases/alerts/carotid.html   (1138 words)

[Clinical Preventive Services] Screening for Asymptomatic Carotid Artery Stenosis   (Site not responding. Last check: 2007-10-18) The prevalence of hemodynamically significant carotid stenosis varies with age and other risk factors: population-based studies estimate that 0.5% of persons in their 50s and about 10% of those over age 80 have carotid stenosis greater than 50%.11 The proportion of all strokes attributable to previously asymptomatic carotid stenosis seems to be small, however. Although auscultation of the carotid arteries is widely considered a routine component of the physical examination, the Canadian Task Force on the Periodic Health Examination53 recommended against screening for bruits in asymptomatic persons, based on the poor sensitivity and specificity of cervical bruits as an indicator of significant carotid stenosis.

NeurosurgeryToday.org | What is Neurosurgery | Patient Education Materials | carotid endarterectomy Carotid endarterectomy is a common vascular surgical procedure which may help prevent your risk of having a stroke. Carotid arteries are located on each side of your neck and extend from your aorta in your chest to the base of your skull. Carotid stenting is a procedure in which a tiny, slender metal-mesh tube is fitted inside your carotid artery to increase the flow of blood blocked by plaques. www.neurosurgerytoday.org /what/patient_e/carotid.asp   (1357 words)

DUPLEX SCANNING VERSUS ANGIOGRAPHY IN THE ASSESSMENT OF CAROTID ARTERY STENOSIS The aim of this study was to determine the degree of agreement between Duplex and angiography in the assessment of carotid artery stenosis by analysing the symptomatic and asymptomatic arteries separately. The symptomatic artery was the carotid artery responsible for the patients symptoms, and the opposite artery the asymptomatic side. Combining results from both carotid arteries did improve the agreement rate, but is invalid because the distribution of disease is significantly different in the symptomatic and asymptomatic internal carotid arteries (as shown in tables 2, 3 and 4). www.vascular.co.nz /duplex_paper.htm   (2545 words)

Postgraduate Medicine: Carotid endarterectomy Carotid endarterectomy is appropriate treatment to reduce the risk of ipsilateral stroke in all patients with symptomatic carotid artery stenosis of 50% to 69% who have had a recent nondisabling hemispheric stroke. When a patient has a TIA or nondisabling stroke and is found to have carotid stenosis of 50% or greater on the side corresponding to the ocular or cerebral event, carotid endarterectomy affords an appropriate significant opportunity to prevent a subsequent stroke. Carotid angioplasty with or without stenting is still being evaluated in clinical trials to determine its role in reducing the risk of stroke in patients with carotid artery stenosis. www.postgradmed.com /issues/2000/05_00/ingall_dodick.htm   (3921 words)

Carotid Artery Stenosis The carotid arteries in the front of the neck are major vessels through which blood travels to the brain. The diagnosis of carotid artery stenosis is made noninvasively, beginning with a physical examination and then using either ultrasound or magnetic resonance angiogram. An incision is made along the side of the neck, the carotid artery is opened, plaque is removed, and the artery is closed with a synthetic fabric patch. www.med.nyu.edu /cvinstitute/patients/carotid.html   (225 words)

Carotid stenosis is a marker of generalized atherosclerosis...   (Site not responding. Last check: 2007-10-18) Carotid stenosis is a marker of generalized atherosclerosis and thereby serves as a good predictor of future cerebrovascular, coronary and other vascular events. So, when carotid stenosis is suspected in a symptomatic or asymptomatic case, a comprehensive team approach including internists, neurologists, radiologists, neurosurgeons and vascular surgeons is required for an optimum therapy tailored to the patient. Carotid bruits may be due to stenosis of external carotid arteries transmitted cardiac murmurs, hyperdynamic states, venous hum, arterial kinks or coils. www.indegene.com /Neu/FeatArt/indNeuFeatArt5.html   (2987 words)

Carotid Atherosclerosis Once the diagnosis of significant carotid stenosis is made, the most appropriate therapy is vascular surgery. While carotid endarterectomy has been proven to reduce the risk of stroke, the most common complication associated with surgery is, in fact, stroke, itself. We have published extensively in the area of carotid artery disease, and these papers may be seen in the "Curriculum Vitae" of our surgeons. www.med.nyu.edu /fgpvascular/conditions/carotid.html   (671 words)

Carotid endarterectomy - Wikipedia, the free encyclopedia Carotid endarterectomy is a surgical procedure used to correct carotid stenosis (narrowing of the carotid artery lumen by atheroma), used particularly when this causes medical problems, such as transient ischemic attacks (TIAs) or cerebrovascular accidents (CVAs, strokes). The internal, common and external carotid arteries are clamped, the lumen of the internal carotid artery is opened, and the atheromatous plaque substance removed. Carotid stenosis is diagnosed with ultrasound doppler studies of the neck arteries or magnetic resonance arteriography (MRA). en.wikipedia.org /wiki/Carotid_endarterectomy   (469 words)

CTF Full Text Review: Asymptomatic carotid disease The role of prophylactic carotid endarterectomy or medical intervention such as antiplatelet drugs for asymptomatic patients is still undefined, whatever the degree of stenosis or clinical circumstance (incidental finding or preoperative assessment). The presence and severity of extracranial carotid disease and stenosis increases with age, hypertension and peripheral and coronary vascular disease. Asymptomatic carotid stenosis is generally associated with systemic atherosclerosis and its known complications such as myocardial infarction, stroke and peripheral vascular disease. www.ctfphc.org /Full_Text/Ch57full.htm   (2660 words)

Dotter Interventional Institute | Carotid Stenting Of the more than 100 patients treated by stent placement in the cervical carotid artery, 8 patients were treated for severe carotid dissection, 2 patients for Fibromuscular Dysplasia, and 5 for malignant involvement of the artery. The remainder have been treated for carotid artery stenosis, judged to be at high risk for the conventional surgical approach. The apparent curvilinear density seen overlying the proximal 1/3 of the stent is a subtraction artifact. www.ohsu.edu /dotter/carotid_stenting.htm   (611 words)

Carotid Artery Stenosis Carotid artery stenosis is the narrowing of the carotid arteries. Carotid artery stenosis, also called carotid artery disease, is a major risk factor for ischemic stroke. The stenosis can be easily detected with an ultrasound probe placed on the side of the neck near the carotid arteries. www.americanheart.org /presenter.jhtml?identifier=4497   (348 words)

Stroke secondary to carotid stenosis Stroke secondary to carotid stenosis occurs when blood flow to the brain is blocked. This is usually related to hardening of the arteries (atherosclerosis), particularly those arteries in the neck. A blood clot may occur at the site of the plaque. If a piece of plaque breaks off and travels to an artery in the brain, it can cause a blockage or even a stroke. The risks for stroke secondary to carotid stenosis are the same as atherosclerosis. Often times, patients with stroke secondary to carotid stenosis have atherosclerotic heart disease or diabetes. www.pennhealth.com /ency/article/000751.htm   (455 words)

Carotid stenosis & Coronary artery diease Patients with carotid stenosis frequently have coronary disease.

Carotid.com - Carotid Artery Disease Information for Patients The carotid arteries are the two large blood vessels on either side of the neck. Carotid artery disease occurs when one or both arteries become narrowed or blocked by a buildup of plaque. Once carotid artery disease has been diagnosed, the goal is to reduce the risk of a stroke. www.carotid.com /patients_family.html   (164 words)

Dr. Koop - Stroke secondary to carotid stenosis Stroke secondary to carotid stenosis is a group of brain disorders involving loss of brain function due to the obstruction of blood flow to the brain. Stroke secondary to carotid stenosis occurs when a major portion of one or both carotid arteries (the arteries in the neck that supply blood to the brain) is narrowed or blocked. Stroke secondary to carotid stenosis is most common in older people, and often, there is underlying atherosclerotic heart disease or diabetes mellitus. www.drkoop.com /ency/93/000751.html   (473 words)

Carotid artery stenosis - Wikipedia, the free encyclopedia Carotid arterial stenosis is a narrowing of the lumen of the carotid artery, usually by atheroma (a fatty lump or plaque causing atherosclerosis). If asymptomatic (causing no medical problems), carotid stenosis is generally monitored. If it leads to problems, carotid endarterectomy (surgical removal of the atheroma) may be performed. en.wikipedia.org /wiki/Carotid_stenosis   (129 words)
