Extracranial carotid artery stenosis.
BACKGROUND Carotid endarterectomy is the most common surgical procedure used to treat stenosis of the extracranial precerebral carotid artery. Data from several randomized controlled trials are available to help guide its use in specific patient subgroups. Carotid angioplasty with stenting is also being performed, and clinical trials comparing this procedure with carotid endarterectomy are in p...
متن کاملObserver variability in evaluating extracranial carotid artery stenosis.
One hundred twenty eight cervical carotid arteriograms were twice viewed by three readers for the evaluation of atherosclerotic disease at the carotid bifurcation. Stenoses were estimated using calipers to the nearest 5% and lesions were qualitatively characterized as smooth, irregular, or ulcerated. The intraobserver correlation coefficient between estimates of percent stenosis was .94 overall...
متن کاملDynamic spin labeling angiography in extracranial carotid artery stenosis.
BACKGROUND AND PURPOSE Similar to digital subtraction angiography, dynamic spin labeling angiography (DSLA) provides time-resolved measurements of the influx of blood into the cerebral vascular tree. We determined whether DSLA may help in assessing the degree of stenosis and whether it provides information about intracerebral collateralization and allows us to monitor the hemodynamic effects of...
متن کاملAssociation between plasma homocysteine concentrations and extracranial carotid-artery stenosis.
BACKGROUND Epidemiologic studies have identified hyperhomocysteinemia as a possible risk factor for atherosclerosis. We determined the risk of carotid-artery atherosclerosis in relation to both plasma homocysteine concentrations and nutritional determinants of hyperhomocysteinemia. METHODS We performed a cross-sectional study of 1041 elderly subjects (418 men and 623 women; age range, 67 to 9...
متن کاملTransluminal angioplasty in postsurgical stenosis of the extracranial carotid artery.
Transluminal angioplasty of the common carotid artery was beneficial in a patient with postendarterectomy recurrent stenosis due to fibrous myointimal hyperplasia. This lesion is the major cause of restenosis within the first 24 postoperative months and has histologic characteristics quite favorable for angioplasty with minimal possibility for embolic complications. Since surgery is a proven pr...
