Carotid Artery, Common
The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (CAROTID ARTERY, EXTERNAL) and internal (CAROTID ARTERY, INTERNAL) carotid arteries.
Carotid Stenosis
Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX).

Carotid Body
A small cluster of chemoreceptive and supporting cells located near the bifurcation of the internal carotid artery. The carotid body, which is richly supplied with fenestrated capillaries, senses the pH, carbon dioxide, and oxygen concentrations in the blood and plays a crucial role in their homeostatic control.

Arteriosclerosis
Receptors, Fibrinogen
Receptors that bind FIBRINOGEN through distinct adhesive sequences on the fibrinogen molecule. Although MACROPHAGE-1 ANTIGEN is considered an important signaling molecule for fibrinogen interaction, a variety of INTEGRINS from all three major families, (beta1, beta2, and beta3) have been shown to bind fibrinogen.
Platelet Glycoprotein GPIIb-IIIa Complex
Platelet membrane glycoprotein complex important for platelet adhesion and aggregation. It is an integrin complex containing INTEGRIN ALPHAIIB and INTEGRIN BETA3 which recognizes the arginine-glycine-aspartic acid (RGD) sequence present on several adhesive proteins. As such, it is a receptor for FIBRINOGEN; VON WILLEBRAND FACTOR; FIBRONECTIN; VITRONECTIN; and THROMBOSPONDINS. A deficiency of GPIIb-IIIa results in GLANZMANN THROMBASTHENIA.
Receptor, PAR-1
Receptors, Thrombin
A family of proteinase-activated receptors that are specific for THROMBIN. They are found primarily on PLATELETS and on ENDOTHELIAL CELLS. Activation of thrombin receptors occurs through the proteolytic action of THROMBIN, which cleaves the N-terminal peptide from the receptor to reveal a new N-terminal peptide that is a cryptic ligand for the receptor. The receptors signal through HETEROTRIMERIC GTP-BINDING PROTEINS. Small synthetic peptides that contain the unmasked N-terminal peptide sequence can also activate the receptor in the absence of proteolytic activity.
Receptor, PAR-2
A G-protein-coupled, proteinase-activated receptor that is expressed in a variety of tissues including ENDOTHELIUM; LEUKOCYTES; and the GASTROINTESTINAL TRACT. The receptor is activated by TRYPSIN, which cleaves off the N-terminal peptide from the receptor. The new N-terminal peptide is a cryptic ligand for the receptor. The uncleaved receptor can also be activated by the N-terminal peptide present on the activated THROMBIN RECEPTOR and by small synthetic peptides that contain the unmasked N-terminal sequence.

Cerebral Infarction
The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction).
Subarachnoid Hemorrhage
Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.
Cerebral Hemorrhage
Infarction
Stroke
A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature. (From Adams et al., Principles of Neurology, 6th ed, pp777-810)
Vitronectin inhibits the thrombotic response to arterial injury in mice. (1/264)
Vitronectin (VN) binds to plasminogen activator inhibitor-1 (PAI-1) and integrins and may play an important role in the vascular response to injury by regulating fibrinolysis and cell migration. However, the role of VN in the earliest response to vascular injury, thrombosis, is not well characterized. The purpose of this study was to test the hypothesis that variation in vitronectin expression alters the thrombotic response to arterial injury in mice. Ferric chloride (FeCl3) injury was used to induce platelet-rich thrombi in mouse carotid arteries. Wild-type (VN +/+, n = 14) and VN-deficient (VN -/-, n = 15) mice, matched for age and gender, were studied. Time to occlusion after FeCl3 injury was determined by application of a Doppler flowprobe to the carotid artery. Occlusion times of VN -/- mice were significantly shorter than those of VN +/+ mice (6.0 +/- 1.2 minutes v 17.8 +/- 2.3 minutes, respectively, P < .001). Histologic analysis of injured arterial segments showed that thrombi from VN +/+ and VN -/- mice consisted of dense platelet aggregates. In vitro studies of murine VN +/+ and VN -/- platelets showed no significant differences in ADP-induced aggregation, but a trend towards increased thrombin-induced aggregation in VN -/- platelets. Purified, denatured VN inhibited thrombin-induced platelet aggregation, whereas native VN did not. Thrombin times of plasma from VN -/- mice (20.5 +/- 2.1 seconds, n = 4) were significantly shorter than those of VN +/+ mice (34.2 +/- 6.7 seconds, n = 4, P < .01), and the addition of purified VN to VN -/- plasma prolonged the thrombin time into the normal range, suggesting that VN inhibits thrombin-fibrinogen interactions. PAI-1-deficient mice (n = 6) did not demonstrate significantly enhanced arterial thrombosis compared with wild-type mice (n = 6), excluding a potential indirect antithrombin function of VN mediated by interactions with PAI-1 as an explanation for the accelerated thrombosis observed in VN -/- mice. These results suggest that vitronectin plays a previously unappreciated antithrombotic role at sites of arterial injury and that this activity may be mediated, at least in part, by inhibiting platelet-platelet interactions and/or thrombin procoagulant activity. (+info)Transcranial Doppler directed dextran therapy in the prevention of carotid thrombosis: three hour monitoring is as effective as six hours. (2/264)
BACKGROUND: Six hours' monitoring by transcranial Doppler (TCD) has been successful in directing Dextran therapy in patients at high risk of thrombotic stroke after carotid endarterectomy (CEA). OBJECTIVES: Is 3 h of routine monitoring as effective as 6 h in the prevention of early postoperative thrombotic stroke? DESIGN: Prospective, consecutive study in all patients with an accessible cranial window. METHODS: One hundred and sixty-six patients undergoing CEA underwent 3 h of postoperative monitoring by TCD. Any patient with > 25 emboli detected in any 10 min period or those with emboli that distorted the arterial waveform were commenced on an incremental infusion of dextran 40. RESULTS: The majority of patients destined to embolise will do so within the first 2 postoperative hours. Dextran therapy was instituted in nine patients (5%) and rapidly controlled this phase of embolisation although the dose had to be increased in three (33%). No patient suffered a postoperative carotid thrombosis but one suffered a minor stroke on day 5 and was found to have profuse embolisation on TCD; high dose dextran therapy was again instituted, the embolus count rate fell rapidly and he made a good recovery thereafter. Overall, the death and disabling stroke rate was 1.2% and the death/any stroke rate was 2.4%. CONCLUSION: Three hours of postoperative TCD monitoring is as effective as 6 h in the prevention of postoperative carotid thrombosis. (+info)Inhibitory effects of nimodipine on platelet aggregation and thrombosis. (3/264)
AIM: To study the inhibitory effects of nimodipine (Nim) on rat platelet aggregation and arterial thrombosis in vivo. METHODS: The aggregation rate of platelets induced by ADP and inhibition rate of Nim were measured by the change of light transmission. Effect of Nim on arterial occlusion time was measured by electric stimulation. Effect of Nim on the contents of 6-keto-PGF1 alpha and TXB2 in serum was measured by radioimmunoassay. RESULTS: Nim 4.5, 9, 18, and 36 mg.kg-1.d-1 ig for 4 d restrained the platelet aggregation. The IC50 (95% confidence limits) was 26 (9-44) mg.kg-1. Nim 4.5, 9, and 18 mg.kg-1.d-1 ig for 4 d markedly prolonged the time of thrombotic occlusion in carotid artery induced by electric stimulation. Nim 9 and 18 mg.kg-1.d-1 improved the imbalance of 6-keto-PGF1 alpha/TXB2 in serum after thrombosis. CONCLUSION: Nim was a potent inhibitor of platelet aggregation, which was partially concerned with the improved balance of 6-keto-PGF1 alpha/TXB2. (+info)Recently occluded intracranial and extracranial carotid arteries. Relevance of the unstable atherosclerotic plaque. (4/264)
BACKGROUND AND PURPOSE: It is now widely accepted that thrombotic coronary artery occlusion usually follows rupture of an unstable atherosclerotic plaque. The significance of such instability in arteries supplying the brain is less well appreciated. We therefore describe the clinical and pathological features of recent, symptomatic internal carotid artery occlusion to examine the pathogenetic role of plaque instability at both extracranial and intracranial sites. METHODS: Cases were selected from a consecutive series of 188 adult neuropathology autopsies. In 90 of these, the principal neuropathological abnormality was cerebral infarction, in 14 cases due to recent occlusion of 1 or more segments of the internal carotid artery. In each case, a full systemic, cardiovascular, and neuropathological autopsy was performed. Plaque instability was assessed by the presence or absence of a large, necrotic, lipid core; a thin, fibrous cap; and superficial inflammation. RESULTS: Of the 14 cases, 3 showed extracranial (carotid sinus), 7 intracranial, and 4 both extracranial and intracranial carotid artery occlusion. In 6 of the 7 occluded carotid sinuses, thrombus overlay an ulcerated, unstable, atherosclerotic plaque. In 1 extracranial and all 11 intracranial occlusions, there was either no atheroma or a mildly stenotic, stable, fibrous plaque, and in these cases, the cause of occlusion was embolism (8 cases), giant-cell arteritis (1 case), and unknown (3 cases). CONCLUSIONS: Coronary-type rupture of an unstable atherosclerotic plaque is the usual cause of fatal occlusion of the carotid sinus, but other causes usually underlie intracranial carotid occlusion. The nature and consequences of intracranial atherosclerosis require further study. (+info)Asymptomatic embolization predicts stroke and TIA risk in patients with carotid artery stenosis. (5/264)
BACKGROUND AND PURPOSE: Improved methods of identifying patients at high risk of thromboembolism would allow improved targeting of therapy. One such situation is carotid artery stenosis. This is associated with an increased risk of stroke, which can be reduced by carotid endarterectomy. However, the risk-benefit ratio is low in patients with tight asymptomatic stenosis and moderate symptomatic stenosis. Most stroke in patients with carotid stenosis is believed to be embolic. Therefore, the detection of asymptomatic cerebral emboli using Doppler ultrasound may allow identification of a high-risk group. METHODS: Transcranial Doppler ultrasound was used to record for 1 hour the ipsilateral middle cerebral artery in 111 patients with >60% carotid artery stenosis (69 symptomatic, 42 asymptomatic). The Doppler audio signal was recorded onto digital audio tape for later analysis for embolic signals (ES) by an individual blinded to clinical details. In 67 subjects the relationship between ES and angiographically determined plaque ulceration was investigated. All subjects were followed up prospectively, and the relationship between ES and risk of future ipsilateral carotid artery territory ischemic events (TIA and stroke) was determined. RESULTS: ES were detected in 41(36.9%) subjects. In symptomatic patients there was a significant inverse relationship between the number of ES per hour and time elapsed since last symptoms (Spearman's rho=-0.2558, P=0.034). ES were more common in subjects with plaque ulceration, with a relative risk of 4. 94 (95% CI, 1.23 to 19.84; P=0.025) after controlling for both symptomatic status and degree of stenosis. The presence of ES at entry was predictive of TIA and stroke risk during follow up in both symptomatic (P=0.02) and asymptomatic patients (P=0.007). Considering all 111 patients, the presence of asymptomatic embolization was predictive of a further ischemic event, with an adjusted OR of 8.10 (95% CI, 1.58 to 41.57; P=0.01) after controlling for other cardiovascular risk factors, degree of stenosis, symptomatic status, and aspirin or warfarin use. CONCLUSIONS: Asymptomatic embolization in patients with carotid artery stenosis correlates with known markers of increased stroke risk and is an independent predictor of future stroke risk in patients with both symptomatic and asymptomatic carotid stenosis. It may allow identification of a high-risk group of patients who will particularly benefit from carotid endarterectomy. A large multicenter study is now required to confirm these findings. (+info)Effects of citicoline combined with thrombolytic therapy in a rat embolic stroke model. (6/264)
BACKGROUND AND PURPOSE: We sought to evaluate the effects of the combination of cytidine-5'-diphosphocholine (citicoline) and thrombolysis on infarct size, clinical outcome, and mortality in a rat embolic stroke model. METHODS: Eighty-three Sprague-Dawley rats were embolized in the carotid territory with a single fibrin embolus and randomly assigned to the following treatment groups: (1) control (saline), (2) citicoline 250 mg/kg, (3) citicoline 500 mg/kg, (4) recombinant tissue plasminogen activator (rtPA) 5 mg/kg, (5) rtPA 5 mg/kg plus citicoline 250 mg/kg, and (6) rtPA 5 mg/kg plus citicoline 500 mg/kg. rtPA was administered as a continuous intravenous infusion over 45 minutes starting 45 minutes after embolization; citicoline was given intraperitoneally 30 minutes and 24, 48, and 72 hours after embolization. At 96 hours, the brains were fixed and stained by hematoxylin-eosin, and infarct volumes were measured. Neurological scores were determined daily. RESULTS: The median infarct size, measured as percentage of the affected hemisphere, in the control group was 37% (interquartile range, 26% to 69%) compared with 22% (5% to 52%; P=NS) in group 2, 11% (5% to 34%; P=NS) in group 3, 24% (12% to 31%; P=NS) in group 4, 11% (3% to 22%; P=0.02) in the combined group 5, and 19% (9% to 51%; P=NS) in group 6. The infarct size was significantly reduced in the combined citicoline+rtPA-treated groups to a median of 13% (5% to 30%; P<0.01). Citicoline 500 mg/kg and citicoline combined with rtPA also promoted functional recovery. CONCLUSIONS: These results demonstrate that the combination of low-dose citicoline and rtPA significantly reduced infarct size in this focal ischemia model. (+info)Delayed hypovolemic hypotension exacerbates the hemodynamic and histopathologic consequences of thromboembolic stroke in rats. (7/264)
Abnormalities in cerebrovascular reactivity or hemodynamic reserve are risk factors for stroke. The authors determined whether hemodynamic reserve is reduced in an experimental model of thromboembolic stroke. Nonocclusive common carotid artery thrombosis (CCAT) was produced in rats by a rose bengal-mediated photochemical insult, and moderate hypotension (60 mm Hg/30 min) was induced 1 hour later by hemorrhage. Alterations in local cerebral blood flow (ICBF) were assessed immediately after the hypotensive period by 14C-iodoantipyrine autoradiography, and histopathologic outcome was determined 3 days after CCAT. Compared to normotensive CCAT rats (n = 5), induced hypotension after CCAT (n = 7) led to enlarged regions of severe ischemia (i.e., mean ICBF < 0.24 mL/g/min) in the ipsilateral hemisphere. For example, induced hypotension increased the volume of severely ischemic sites from 16 +/- 4 mm3 (mean +/- SD) to 126 +/- 99 mm3 (P < 0.05). Histopathologic data also showed a larger volume of ischemic damage with secondary hypotension (n = 7) compared to normotension (22 +/- 15 mm3 versus 5 +/- 5 mm3, P < .05). Both hypotension-induced decreases in ICBF and ischemic pathology were commonly detected within cortical anterior and posterior borderzone areas and within the ipsilateral striatum and hippocampus. In contrast to CCAT, mechanical ligation of the common carotid artery plus hypotension (n = 8) did not produce significant histopathologic damage. Nonocclusive CCAT with secondary hypotension therefore predisposes the post-thrombotic brain to hemodynamic stress and structural damage. (+info)Brief myocardial ischemia attenuates platelet thrombosis in remote, damaged, and stenotic carotid arteries. (8/264)
BACKGROUND: Brief antecedent periods of coronary artery occlusion improve subsequent vessel patency in damaged and stenotic coronary arteries via release of adenosine from ischemic/reperfused myocardium and resultant adenosine receptor stimulation. However, the site of receptor stimulation-circulating blood-borne elements (ie, platelets) versus vessel-wall components of the culprit artery-remains unclear. If platelet adenosine receptors are involved, then the benefits of brief coronary occlusion (1) should be manifested systemically and improve patency at a remote site and (2) should be inhibited by an antagonist of adenosine A(2) receptors, whereas, in contrast, (3) brief vascular occlusion not associated with appreciable adenosine release should be ineffective in improving vessel patency. METHODS AND RESULTS: In Protocol 1, anesthetized rabbits received 5 minutes of transient coronary occlusion, 5 minutes of transient bilateral carotid occlusion (purported to cause negligible adenosine release from the brain), or no intervention. All rabbits then underwent injury plus stenosis of the left carotid artery, resulting in repeated cyclic variations in carotid blood flow (CFVs). Carotid patency during the initial 2 hours after stenosis (assessed by quantifying the nadir of the CFVs and area of the flow-time profile) was significantly enhanced with antecedent coronary-but not carotid-occlusion versus controls. In Protocol 2, improvement in carotid patency after brief coronary occlusion was corroborated in anesthetized dogs. However, the benefits of brief coronary occlusion were abrogated by the A(2)/A(1) antagonist CGS 15943. CONCLUSIONS: Brief antecedent coronary artery occlusion enhanced vessel patency in remote, damaged, and stenotic carotid arteries, largely due to adenosine receptor stimulation on circulating elements.
