Anterior Cerebral Artery: Artery formed by the bifurcation of the internal carotid artery (CAROTID ARTERY, INTERNAL). Branches of the anterior cerebral artery supply the CAUDATE NUCLEUS; INTERNAL CAPSULE; PUTAMEN; SEPTAL NUCLEI; GYRUS CINGULI; and surfaces of the FRONTAL LOBE and PARIETAL LOBE.Infarction, Anterior Cerebral Artery: NECROSIS occurring in the ANTERIOR CEREBRAL ARTERY system, including branches such as Heubner's artery. These arteries supply blood to the medial and superior parts of the CEREBRAL HEMISPHERE, Infarction in the anterior cerebral artery usually results in sensory and motor impairment in the lower body.Cerebral Arteries: The arterial blood vessels supplying the CEREBRUM.Cerebral Angiography: Radiography of the vascular system of the brain after injection of a contrast medium.Intracranial Aneurysm: Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)Middle Cerebral Artery: The largest of the cerebral arteries. It trifurcates into temporal, frontal, and parietal branches supplying blood to most of the parenchyma of these lobes in the CEREBRAL CORTEX. These are the areas involved in motor, sensory, and speech activities.Circle of Willis: A polygonal anastomosis at the base of the brain formed by the internal carotid (CAROTID ARTERY, INTERNAL), proximal parts of the anterior, middle, and posterior cerebral arteries (ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; POSTERIOR CEREBRAL ARTERY), the anterior communicating artery and the posterior communicating arteries.Cerebral Arterial Diseases: Pathological conditions of intracranial ARTERIES supplying the CEREBRUM. These diseases often are due to abnormalities or pathological processes in the ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; and POSTERIOR CEREBRAL ARTERY.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).Infarction, Middle Cerebral Artery: NECROSIS occurring in the MIDDLE CEREBRAL ARTERY distribution system which brings blood to the entire lateral aspects of each CEREBRAL HEMISPHERE. Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the 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.Aneurysm, Ruptured: The tearing or bursting of the weakened wall of the aneurysmal sac, usually heralded by sudden worsening pain. The great danger of a ruptured aneurysm is the large amount of blood spilling into the surrounding tissues and cavities, causing HEMORRHAGIC SHOCK.Cerebrovascular Circulation: The circulation of blood through the BLOOD VESSELS of the BRAIN.Tomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Carotid Artery, Internal: Branch of the common carotid artery which supplies the anterior part of the brain, the eye and its appendages, the forehead and nose.Ultrasonography, Doppler, Transcranial: A non-invasive technique using ultrasound for the measurement of cerebrovascular hemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum.Basilar Artery: The artery formed by the union of the right and left vertebral arteries; it runs from the lower to the upper border of the pons, where it bifurcates into the two posterior cerebral arteries.Magnetic Resonance Angiography: Non-invasive method of vascular imaging and determination of internal anatomy without injection of contrast media or radiation exposure. The technique is used especially in CEREBRAL ANGIOGRAPHY as well as for studies of other vascular structures.Brain Ischemia: Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.Blood Flow Velocity: A value equal to the total volume flow divided by the cross-sectional area of the vascular bed.Cerebral Revascularization: Microsurgical revascularization to improve intracranial circulation. It usually involves joining the extracranial circulation to the intracranial circulation but may include extracranial revascularization (e.g., subclavian-vertebral artery bypass, subclavian-external carotid artery bypass). It is performed by joining two arteries (direct anastomosis or use of graft) or by free autologous transplantation of highly vascularized tissue to the surface of the brain.Echoencephalography: Use of reflected ultrasound in the diagnosis of intracranial pathologic processes.Intracranial Embolism and Thrombosis: Embolism or thrombosis involving blood vessels which supply intracranial structures. Emboli may originate from extracranial or intracranial sources. Thrombosis may occur in arterial or venous structures.Arteries: The vessels carrying blood away from the heart.Vasospasm, Intracranial: Constriction of arteries in the SKULL due to sudden, sharp, and often persistent smooth muscle contraction in blood vessels. Intracranial vasospasm results in reduced vessel lumen caliber, restricted blood flow to the brain, and BRAIN ISCHEMIA that may lead to hypoxic-ischemic brain injury (HYPOXIA-ISCHEMIA, BRAIN).Ischemic Attack, Transient: Brief reversible episodes of focal, nonconvulsive ischemic dysfunction of the brain having a duration of less than 24 hours, and usually less than one hour, caused by transient thrombotic or embolic blood vessel occlusion or stenosis. Events may be classified by arterial distribution, temporal pattern, or etiology (e.g., embolic vs. thrombotic). (From Adams et al., Principles of Neurology, 6th ed, pp814-6)Carotid Arteries: Either of the two principal arteries on both sides of the neck that supply blood to the head and neck; each divides into two branches, the internal carotid artery and the external carotid artery.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Angiography, Digital Subtraction: A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.Neurosurgical Procedures: Surgery performed on the nervous system or its parts.Arterial Occlusive Diseases: Pathological processes which result in the partial or complete obstruction of ARTERIES. They are characterized by greatly reduced or absence of blood flow through these vessels. They are also known as arterial insufficiency.Intracranial Arteriovenous Malformations: Congenital vascular anomalies in the brain characterized by direct communication between an artery and a vein without passing through the CAPILLARIES. The locations and size of the shunts determine the symptoms including HEADACHES; SEIZURES; STROKE; INTRACRANIAL HEMORRHAGES; mass effect; and vascular steal effect.Brain Hemorrhage, Traumatic: Bleeding within the brain as a result of penetrating and nonpenetrating CRANIOCEREBRAL TRAUMA. Traumatically induced hemorrhages may occur in any area of the brain, including the CEREBRUM; BRAIN STEM (see BRAIN STEM HEMORRHAGE, TRAUMATIC); and CEREBELLUM.Embolization, Therapeutic: A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.Vertebral Artery: The first branch of the SUBCLAVIAN ARTERY with distribution to muscles of the NECK; VERTEBRAE; SPINAL CORD; CEREBELLUM; and interior of the CEREBRUM.Posterior Cerebral Artery: Artery formed by the bifurcation of the BASILAR ARTERY.

(Dorland, 28th ed)Akinetic Mutism: A syndrome characterized by a silent and inert state without voluntary motor activity despite preserved sensorimotor pathways and vigilance. Bilateral FRONTAL LOBE dysfunction involving the anterior cingulate gyrus and related brain injuries are associated with this condition. This may result in impaired abilities to communicate and initiate motor activities. (From Adams et al., Principles of Neurology, 6th ed, p348; Fortschr Neurol Psychiatr 1995 Feb;63(2):59-67)Intracranial Arteriosclerosis: Vascular diseases characterized by thickening and hardening of the walls of ARTERIES inside the SKULL. There are three subtypes: (1) atherosclerosis with fatty deposits in the ARTERIAL INTIMA; (2) Monckeberg's sclerosis with calcium deposits in the media and (3) arteriolosclerosis involving the small caliber arteries. Clinical signs include HEADACHE; CONFUSION; transient blindness (AMAUROSIS FUGAX); speech impairment; and HEMIPARESIS.Cerebrovascular Disorders: A spectrum of pathological conditions of impaired blood flow in the brain. They can involve vessels (ARTERIES or VEINS) in the CEREBRUM, the CEREBELLUM, and the BRAIN STEM. Major categories include INTRACRANIAL ARTERIOVENOUS MALFORMATIONS; BRAIN ISCHEMIA; CEREBRAL HEMORRHAGE; and others.Moyamoya Disease: A noninflammatory, progressive occlusion of the intracranial CAROTID ARTERIES and the formation of netlike collateral arteries arising from the CIRCLE OF WILLIS. Cerebral angiogram shows the puff-of-smoke (moyamoya) collaterals at the base of the brain. It is characterized by endothelial HYPERPLASIA and FIBROSIS with thickening of arterial walls. This disease primarily affects children but can also occur in adults.Cerebral Hemorrhage: Bleeding into one or both CEREBRAL HEMISPHERES including the BASAL GANGLIA and the CEREBRAL CORTEX. It is often associated with HYPERTENSION and CRANIOCEREBRAL TRAUMA.Magnetic Resonance Imaging: Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.Aneurysm, Dissecting: Aneurysm caused by a tear in the TUNICA INTIMA of a blood vessel leading to interstitial HEMORRHAGE, and splitting (dissecting) of the vessel wall, often involving the AORTA. Dissection between the intima and media causes luminal occlusion. Dissection at the media, or between the media and the outer adventitia causes aneurismal dilation.Surgical Instruments: Hand-held tools or implements used by health professionals for the performance of surgical tasks.Ultrasonography, Doppler: Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow. (Stedman, 25th ed)Collateral Circulation: Maintenance of blood flow to an organ despite obstruction of a principal vessel. Blood flow is maintained through small vessels.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)Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.Regional Blood Flow: The flow of BLOOD through or around an organ or region of the body.Hematoma: A collection of blood outside the BLOOD VESSELS. Hematoma can be localized in an organ, space, or tissue.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). (From Adams et al., Principles of Neurology, 6th ed, pp 822-3)Pulmonary Artery: The short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs.Ultrasonography: The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.Frontal Lobe: The part of the cerebral hemisphere anterior to the central sulcus, and anterior and superior to the lateral sulcus.Cerebral Palsy: A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)Carotid Artery Diseases: Pathological conditions involving the CAROTID ARTERIES, including the common, internal, and external carotid arteries. ATHEROSCLEROSIS and TRAUMA are relatively frequent causes of carotid artery pathology.Mesenteric Arteries: Arteries which arise from the abdominal aorta and distribute to most of the intestines.Renal Artery: A branch of the abdominal aorta which supplies the kidneys, adrenal glands and ureters.Femoral Artery: The main artery of the thigh, a continuation of the external iliac artery.Retrospective Studies: Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.Hematoma, Subdural: Accumulation of blood in the SUBDURAL SPACE between the DURA MATER and the arachnoidal layer of the MENINGES. This condition primarily occurs over the surface of a CEREBRAL HEMISPHERE, but may develop in the spinal canal (HEMATOMA, SUBDURAL, SPINAL). Subdural hematoma can be classified as the acute or the chronic form, with immediate or delayed symptom onset, respectively. Symptoms may include loss of consciousness, severe HEADACHE, and deteriorating mental status.Postoperative Complications: Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.Intracranial Embolism: Blocking of a blood vessel in the SKULL by an EMBOLUS which can be a blood clot (THROMBUS) or other undissolved material in the blood stream.

Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS).

Larger anastomoses in angiotensinogen-knockout mice attenuate early metabolic disturbances after middle cerebral artery occlusion. (1/108)

Abnormalities in the homeostasis of the renin-angiotensin system have been implicated in the pathogenesis of vascular disorders, including stroke. The authors investigated whether angiotensinogen (AGN) knockout mice exhibit differences in brain susceptibility to focal ischemia, and whether such differences can be related to special features of the collateral circulation. Wild-type and AGN-knockout mice were submitted to permanent suture occlusion of the middle cerebral artery (MCA). The collateral vascular system was visualized by systemic latex infusion, and the ischemic lesions were identified by cresyl-violet staining. The core and penumbra of the evolving infarct were differentiated by bioluminescence and autoradiographic imaging of ATP and protein biosynthesis, respectively. In wild-type mice, mean arterial blood pressure was 95.0 +/- 8.6 mm Hg, and the diameter of fully relaxed anastomotic vessels between the peripheral branches of the anterior and middle cerebral arteries 26.6 +/- 4.0 microm. In AGN knockouts, mean arterial blood pressure was significantly lower, 71.5 +/- 8.5 mm Hg (P < .01), and the anastomotic vessels were significantly larger, 29.4 +/- 4.6 microm (P < .01). One hour after MCA occlusion, AGN-knockout mice exhibited a smaller ischemic core (defined as the region of ATP depletion) but a larger penumbra (the area of disturbed protein synthesis with preserved ATP). At 24 hours after MCA occlusion, this difference disappeared, and histologically visible lesions were of similar size in both strains. The observations show that in AGN-knockout mice the more efficient collateral blood supply delays ischemic injury despite the lower blood pressure. Pharmacologic suppression of angiotensin formation may prolong the therapeutic window for treatment of infarcts.  (+info)

Flow dynamics in a lethal anterior communicating artery aneurysm. (2/108)

We describe and analyze the flow dynamics in replicas of a human anterior communicating artery aneurysm. The replicas were placed in a circuit of pulsating non-Newtonian fluid, and flows were adjusted to replicate human physiologic parameters. Individual slipstreams were opacified with isobaric dyes, and images were recorded on film and by CT/MR angiography. When flow in the afferent (internal carotid) and efferent (anterior and middle cerebral) arteries was bilaterally equal, slipstreams rarely entered the aneurysm. When flow in either the afferent or efferent vessels was not symmetrical, however, slipstreams entered the aneurysm neck, impinged upon the aneurysm dome, and swirled within the aneurysm. Unequal flow in carotid or cerebral systems may be necessary to direct pathologic, fluid slipstreams into an aneurysm.  (+info)

Hemodynamic changes around cerebral arteriovenous malformation before and after embolization measured with PET. (3/108)

To estimate the changes in regional cerebral blood flow (rCBF) around cerebral arteriovenous malformation (AVM) before and after embolization, 6 patients with AVM were sequentially examined with positron emission tomography (PET). PET depicted the remodeling of rCBF in the ipsilateral hemisphere of AVM after embolization. Decrease of rCBF in the ipsilateral hemisphere was also detected in patients with focal symptoms before embolization, and improvement of clinical symptoms after embolization corresponded to disappearance of rCBF decrease. PET can detect hemodynamic changes after embolization, and has a possibility to estimate the effect of embolization in patients with AVM.  (+info)

Neuropsychological changes after surgery for anterior communicating artery aneurysm. (4/108)

Neuropsychological disturbances following surgery for anterior communicating artery aneurysms were analyzed in 26 patients (11 males, 15 females) using the Hasegawa dementia scale-revised (HDS-R) over a 3-year period. The patients were aged from 34 to 76 years (mean 54.1 years). Lesions in the frontal lobe were evaluated using computed tomography (CT). Twenty-three patients had symptoms over the course. Four patients had basal forebrain lesion, five had ventral frontal lesion, and 12 had no lesion. Patients with basal forebrain lesion and no lesion tended to show disorientation. The mean HDS-R score was 10.2 points in the patients with ventral frontal lesion, and 13.5 points in the patients with no lesion. These scores are within the range for dementia. The mean HDS-R score in patients with basal forebrain and striate lesions was over 25 points and beyond the range for dementia. Significant differences were observed in the HDS-R score between patients with ventral frontal lesion and basal forebrain lesion, and between patients with no lesion and basal forebrain lesion (p < 0.05). Recovery from neuropsychological disturbances was poorer in patients with ventral frontal lesion and no lesion compared to those with basal forebrain and striate lesions, and their symptoms tended to persist.  (+info)

Prolapsing gyrus rectus as a cause of progressive optic neuropathy. (5/108)

The pathogenesis of optic neuropathy caused by neurovascular compression or by similar mechanisms is unclear. Thin-slice magnetic resonance (MR) imaging was performed in 69 patients with optic neuropathy without demonstrable ophthalmological lesions (57.0 +/- 17.1 years of age) and 102 normal subjects (57.7 +/- 13.9 years of age). The MR imaging features were classified into "no compression" by the internal carotid artery (ICA), "compression" by the ICA, "no contact" with the anterior cerebral artery (ACA) or the gyrus rectus, "contact" with either or both, "compression" by the ACA, and "compression" by the gyrus rectus. The Spearman correlation coefficients were calculated between patients or controls, the MR classification, and the age, and the number of patients in each MR classification were evaluated by the chi 2 test. Five of the 69 patients with rapidly progressive symptoms were operated on via the frontotemporal approach. The MR imaging feature of "compression" by the gyrus rectus was the best predictor of optic neuropathy (Spearman correlation coefficients rho = -0.23646, p < 0.0018). This MR imaging feature was observed in 38 of 69 patients and in 32 of 102 controls (p = 0.002). Compression of the nerve by the gyrus rectus or the ACA was confirmed in all five operated cases. Decompression of the nerve was fully achieved in four of the five patients, and their symptoms have not progressed since then. Optic neuropathies due to compression by the prolapsing gyrus rectus are not well understood. Such neuropathies may be detected by MR imaging.  (+info)

Ruptured aneurysm at the origin of the median artery of the corpus callosum associated with accessory middle cerebral artery--case report. (6/108)

A 62-year-old male presented with ruptured anterior communicating artery (ACoA) aneurysm manifesting as severe headache associated with the rare combination of median artery of the corpus callosum (MACC) and accessory middle cerebral artery (MCA). Computed tomography demonstrated diffuse subarachnoid hemorrhage. Left carotid angiography demonstrated an anomalous vessel originating from the ACoA complex and passing forward in the interhemispheric fissure between the two companion A2 segments. This vessel was identified as the MACC. Another anomalous vessel originated from the left A1-A2 segment and passed into the sylvian fissure. This vessel was identified as the accessory MCA. Left frontotemporal craniotomy was performed to clip the neck of the aneurysm. After identifying both A1 and A2 segments, accessory MCA, and the MACC, the aneurysm neck was occluded successfully. The ACoA complex is one of the most frequent sites of vascular anomalies. Preoperative and intraoperative care is required to identify the presence of anomalies of the ACoA complex prior to clip placement, to avoid accidental damage or clipping, which may result in severe neurological deficits.  (+info)

Histomorphometrical study of the elastic fiber system in the anterior cerebral artery of man. (7/108)

The aim of the present study was to quantify the distribution of the elastic fiber system within the wall of the anterior cerebral artery. The study is based on the works of Glynn (1940) and Stehbens (1989) concerning the incidence and origin of brain aneurysms and recent studies of the elastic fibers. The anterior cerebral artery was divided into three segments, S1, S2 and S3: S1 corresponds to the origin of the anterior cerebral artery, S2 is located at the junction of the anterior cerebral artery with the anterior communicating artery, and S3 at the junction of the rostrum and genu of the corpus callosum,which were submitted to routine histological procedures. A histomorphometrical study was undertaken using an estimation of the linear density (Ld) of the components of the fibrous elastic system which evaluates their full length in each segment. Data were analyzed using first order linear regression methods. The results show a decreasing quantity of elastic fibers in the three segments (S1>S2>S3). Study of the elastic fiber system may originate new concepts regarding the genesis of cerebral artery aneurysm.  (+info)

A modified transorbital baboon model of reperfused stroke. (8/108)

BACKGROUND AND PURPOSE: Although pathophysiological studies of focal cerebral ischemia in nonhuman primates can provide important information not obtainable in rodent models, primate experimentation is limited by considerations of cost, availability, effort, and ethics. A reproducible and quantitative model that minimizes the number of animals necessary to detect differences between treatment groups is therefore crucial. METHODS: Eight male baboons (weight, 22+/-2 kg) underwent left transorbital craniectomy followed by 1 hour of temporary ipsilateral internal carotid artery occlusion at the level of the anterior choroidal artery together with bilateral temporary occlusion of both anterior cerebral arteries (A1) proximal to the anterior communicating artery. A tightly controlled nitrous oxide-narcotic anesthetic allowed for intraoperative motor evoked potential confirmation of middle cerebral artery (MCA) territory ischemia. Animals survived to 72 hours or 10 days if successfully self-caring. Outcomes were assessed with a 100-point neurological grading system, and infarct volume was quantified by planimetric analysis of both MRI and triphenyltetrazolium chloride-stained sections. RESULTS: Infarction volumes (on T2-weighted images) were 32+/-7% (mean+/-SEM) of the ipsilateral hemisphere, and neurological scores averaged 29+/-9. All animals demonstrated evidence of hemispheric infarction, with damage evident in both cortical and subcortical regions in the MCA vascular territory. Histologically determined infarction volumes differed by <3% and correlated with absolute neurological scores (r=0.9, P:=0.003). CONCLUSIONS: Transorbital temporary occlusion of the entire anterior cerebral circulation with strict control of physiological parameters can reliably produce reperfused MCA territory infarction. The magnitude of the resultant infarct with little interanimal variability diminishes the potential number of animals required to distinguish between 2 treatment regimens. The anatomic distribution of the infarct and associated functional deficits offer comparability to human hemispheric strokes.  (+info)

The anterior ulnar recurrent artery is an artery in the forearm. It is one of two recurrent arteries that arises from the ulnar artery, the other being the posterior ulnar recurrent artery. It arises from the ulnar artery immediately below the elbow-joint, runs upward between the brachialis and pronator teres muscle and supplies twigs to those muscles. In front of the medial epicondyle it anastomoses with the superior and Inferior ulnar collateral arteries.

RESULTS: A total of 24 RAHs were recognised in 20 patients: 7 arose from the A1, 5 from the anterior cerebral artery (ACA)-anterior communicating artery (Acom), 11 from the A2, whereas in 1 case, the segment of origin from the ACA could not be identified. Seventeen arteries arose from the lateral wall of the ACA and seven from the superior wall of the A1 segment of the ACA. The RAH was bilaterally seen in 3 patients and unilaterally in 17 with one double RAH. Five RAHs were visible only after contrast injection in the contralateral internal carotid artery. A horizontal segment was visible in 7 arteries, a horizontal followed by a vertical segment without visible intraparenchymal branching pattern was seen in 6 and a horizontal and vertical segment with visible intraparenchymal branching pattern was seen in 11. In five, the artery made a half loop with an inferior-convex curve just before the vertical segment, and in two cases, a full loop was observed ...

Translated literally as "hazy puff of smoke" in Japanese, Moya moya is a chronic cerebrovascular occlusive disease involving the Circle of Willis. The pathologic findings of Moya moya include intimal thickening and internal elastic lamina disruption of the arteries of the Circle of Willis and collateral vessels. The angiographic features of the disease include bilateral stenosis or occlusion of the supraclinoid portion of the internal carotid artery that extends to the proximal portions of the anterior cerebral artery and middle cerebral artery, as well as the presence of parenchymal, leptomeningeal, or transdural collateral vessels that supply the ischemic brain. These collateral vessels are typified by a meshwork appearance. Aneurysm formation is quite common, most often affecting the anterior communicating and anterior cerebral arteries with unilateral Moya moya, and basilar artery with bilateral Moya moya. Extracranial involvement of Moya moya has been described in the literature, most ...

Researchers monitored the volunteers blood flow through their brains with an ultrasound. They found that increased blood flow through the anterior cerebral artery, located in the middle of the brain behind the eyes, caused it to swell up suddenly as the temperature dropped. This causes the pain we know as brain freeze.. The scientists described this act as a defensive mechanism for the brain. Since the temperature drops and the brain requires warmth to work, this widening of the artery provides a way to move the coldness along quicker and return the artery to its normal temperature. So the next time you get a blindly headache after downing a milkshake, know thats just your brains way of protecting itself. ...
Ischemic lesions within the territory of the anterior cerebral artery present with a variety of clinical signs and symptoms. Among these, frontal alien hand syndrome is rare and easily overlooked in the acute clinical setting, but significantly impacts on functional activities of daily life. Given its rareness, very little is known about its long-term outcome. To shade some more light onto this issue, clinical presentation, course of rehabilitation and outcome of two illustrative cases of frontal alien hand syndrome following anterior cerebral artery stroke are presented. Within seven and nine months from symptom onset, respectively, the clinical symptoms of frontal alien hand had resolved completely in both cases. We conclude that frontal alien hand syndrome has a favourable long-term outcome.

Results 23 cerebral aneurysms in 22 patients were treated with the Pipeline device at our institution during our studys time period. 18 patients were female (81.8%) and four male (18.2%), with a mean age of 59.5 years (median 63 years, range 31-81 years). 22 aneurysms were unruptured (95.3%) and one was ruptured (4.3%). Aneurysm locations were: seven in the internal carotid artery (ICA) below the ophthalmic artery (30.4%), six in the periophthalmic ICA (26.1%), five in the supraclinoid ICA (21.7%), two in the middle cerebral artery (8.7%), one in the anterior cerebral artery (4.3%), one in the vertebral artery (4.3%), and one in the basilar artery (4.3%). Mean maximum aneurysm sac dimension was 11.4 mm (median 10 mm, range 2.1-27 mm) and mean aneurysm neck size was 5.6 mm (median 4.8 mm, range 1.4-17 mm). Mean number of Pipeline devices deployed was 1.3 (median 1, range 1-5). Dyna-CTA was performed in 15 cases (65.2%) and balloon angioplasty of the Pipeline construct to achieve adequate wall ...
From February 2002 to October 2003, we performed MRA of coiled intracranial aneurysms for long-term follow-up or as a baseline for follow-up after coil placement in patients who gave informed consent. MRA as a baseline was scheduled in an early period after coil placement and in a period around follow-up DSA in the chronic phase. Seventy patients with 70 coiled aneurysms uneventfully and successfully underwent 98 MRA studies. Included in this study were MRA images obtained within 3 days after coil placement (early phase, n = 24), and MRA within 7 days of follow-up DSA 5-41 (9 ± 7) months after coil placement (chronic phase, n = 27). Consequently, 51 MRA studies of 39 coiled aneurysms (two ruptured) of 39 patients were compared with the corresponding DSA studies. The mean age ± SD of the patients was 59 years ± 9; nine patients were male. Aneurysms were located in internal carotid artery (n = 27), anterior cerebral artery (n = 1), basilar artery (n = 10), and vertebral artery (n = 1). Maximum ...
The patients with subarachnoid haemorrhage in this study were selected because they showed secondary cererebral hypoxia/ischaemia of varying severity. Thus case 1 had a long lasting episode of secondary ischaemia leading to cerebral infarction in the microdialyisis probe area, cases 2 and 3 temporary secondary hypoxia/ischaemia without infarction in the probe area, and case 4 minor disturbances of energy metabolism and no structural changes in the frontal lobe harbouring the microdialyisis probe.The ischaemic event in case 1 was associated with a pronounced increase of D-glycerol. This probably reflected profound ischaemia with energy failure as the D-L/P ratio rise was large and accompanied by an undetectable D-glucose concentration and increased D-hypoxanthine and D-glutamate.15 This was supported by the occlusion of the right anterior cerebral artery diagnosed by a second angiography and the infarct development in the microdialyisis probe area according to CT and PET.15 In view of these ...

Aneurysms located in the distal intracranial vessels are rare. Distal aneurysms represent approximately 7% to 9% of anterior cerebral artery aneurysms, 2% to 7% of middle cerebral artery aneurysms, and 5% of posterior cerebral artery aneurysms (6). Aneurysms of the distal superior cerebellar artery (SCA) and PICA are rare. Locksley et al (1), in a series of 2349 intracranial aneurysms, found six aneurysms of the SCA (0.3%) and 11 of the PICA (0.5%). Gacs et al (2), in a surgical series of 910 vertebrobasilar aneurysms, reported six distal aneurysms of the SCA (0.7%) and eight aneurysms of the PICA (0.9%).. The poor prognosis in patients with ruptured intracranial aneurysms of the posterior circulation was documented in 1995 by Schievink et al (6). In their series, the 48-hour survival rate was 32% for aneurysms of the posterior circulation and 77% for aneurysms of the anterior circulation. The 30-day survival rate was 11% and 53%, respectively.. Outcome after surgery, depending on the location ...
To elucidate the role of the internal elastic lamina in the development of cerebral aneurysm, the bifurcation of the anterior cerebral artery and olfactory artery was histologically studied in control and experimental rats treated with unilateral carotid ligation and renal hypertension. Various stages of aneurysm formation were compared, and it was found that early aneurysmal changes were always present just distal to the apical intimal pad on the anterior cerebral artery side. The internal elastic lamina was thinned and fragmented just distal to the pad even in the very early stage of aneurysm formation when the medial layer was still present. In control rats, the internal elastic lamina had a tendency to thin and fragment at the site where aneurysms would develop in experimental rats. Our study shows that changes of the internal elastic lamina were present just distal to the pad even in control rats, which never develop cerebral aneurysms. Under hemodynamic stress augmented by experimental ...
The ultrastructural distribution of the autonomic nerves of brain arteries was investigated in renal (one-kidney, one clip) hypertensive and normotensive Wistar-Kyoto rats. Sympathetic and nonsympathetic nerve terminals were found only in the adventitial layer of brain arteries of renal hypertensive and normotensive rats. In both normotensive and renal hypertensive rats the total nerve endings were dense in anterior cerebral artery, moderately dense in middle cerebral artery, and sparse in basilar artery. In normotensive rats, nonsympathetic nerves outnumbered sympathetic nerves in anterior cerebral, middle cerebral, and basilar arteries. In renal hypertensive rats these two types of nerve terminals in close apposition to smooth muscle decreased in anterior cerebral and basilar arteries, while those in middle cerebral arteries remained unchanged. These results suggest that the potential neurogenic control of cerebral blood vessels as well as the trophic effect of sympathetic nerves on brain ...
BACKGROUND The aim of the present study was to evaluate the technical viability of the unilateral pterional approach to simultaneously treat symmetrical bilateral aneurysm (mirror image) of the middle cerebral arteries (SBAMCA) and to determine the morbidity and mortality rates of this approach. METHODS Forty-six patients with SBAMCA underwent unilateral pterional craniotomy within a period of 9 years. Most patients were women (24, 80.0%) and mean age was 40.7 years. RESULTS Obliteration of the contralateral aneurysm was not possible in 16 patients (34.8%) because of brain edema in 8 patients operated on during the acute phase, lateral projection of the aneurysm in 3, a very long contralateral M1 segment in 4, and the presence of atheromatous plaques at the MCA bifurcation and aneurysm neck in 1. The remaining 30 patients (65.2%) were submitted to the proposed treatment. Final evaluation showed that 26 patients (86.7%) were Glasgow Outcome Scale (GOS) V, 1 patient (3.3%) was GOS IV, 2 patients (6.6%
The Circle of Willis or the Circulus Arteriosus is the main arterial anastomatic trunk of the brain. According to Bhatnagar and Andy, 1995, anastomosis occurs when blood vessels bring blood to one spot from which it is then redistributed. The Circle of Willis is a point where the blood carried by the two internal carotids and the basilar system comes together and then is redistributed by the anterior, middle, and posterior cerebral arteries. The anterior cerebral arteries of the two hemispheres are joined together by the anterior communicating artery. The middle cerebral arteries are linked to the posterior cerebral arteries by the posterior communicating arteries. This anastamosis or communication between arteries make collateral circulation which Love and Webb, 1995, define as "the flow of blood through an alternate route" (p. 40) possible. This is a safety mechanism, allowing brain areas to continue receiving adequate blood supply even when there is a blockage somewhere in an arterial system. ...
Variations of the Circle of Willis at the End of the Human Embryonic Period[4] "Variations of the circle of Willis (CW) influence blood supply to the brain and adjacent structures in adults. We examined the formation of the CW in 20 human embryo samples at the end of the embryonic period using 3-D reconstructions of serial histological sections. The CW was closed in all samples, and did not form in a single plane, but was composed of multiple stair-like planes. The artery acutely curved at the caudal part of the CW, namely, at the inlet of the basilar artery and bifurcation of the P1 segment of the posterior cerebral artery (PCA), reflecting flexure of the mesencephalon and diencephalon at this stage. Variations were observed in 17 of 20 samples-only anterior parts (anterior communicating artery [Acom] and anterior cerebral artery [ACA]) in 10 samples, only posterior parts (posterior communicating artery [Pcom]) in one sample, and both anterior and posterior parts in six samples. Variations ...

A patient developed weakness of the right leg and homolateral ataxia of the arm, caused by a subcortical infarct in the area supplied by the anterior cerebral artery in the left paracentral region, demonstrated by CT and MRI. Cerebral blood flow studied by technetium-labelled hexamethyl-propylene-amine oxime using single photon emission computed tomography showed decreased blood flow in the left lateral frontal cortex and in the right cerebellar hemisphere ("crossed cerebral-cerebellar diaschisis"). The homolateral ataxia of the arm may be caused by decreased function of the right cerebellar hemisphere, because of a lesion of the corticopontine-cerebellar tracts, whereas crural hemiparesis is caused by a lesion of the upper part of the corona radiata.. ...

BACKGROUND AND PURPOSE: Current knowledge of the collateral circulation remains sparse, and a noninvasive method to better characterize the role of collaterals is desirable. The aim of our study was to investigate the presence and distal flow of collaterals by using a new MR perfusion territory imaging, vessel-encoded arterial spin-labeling (VE-ASL). MATERIALS AND METHODS: Fifty-six patients with internal carotid artery (ICA) or middle cerebral artery (MCA) stenosis were identified by sonography, VE-ASL was performed to assess the presence and function of collateral flow. The perfusion information was combined with VE maps into high signal-intensity-to-noise-ratio 3-colored maps of the left carotid, right carotid, and posterior circulation territories. The presence of the anterior and posterior collateral flow was demonstrated by the color of the standard anterior cerebral artery/MCA flow territory. The distal function of collateral flow was categorized as adequate (cerebral blood flow [CBF] >= ...
It starts at the carotid sinus at bifurcation of CCA at the level of the upper border of the thyroid cartilage at the level of the fourth cervical vertebra. It ascends just behind and lateral to the hypopharynx where it can be palpated (Hollinshead 1982). It passes up the neck without any branches to the base of the skull where it enters the carotid canal of the petrous bone. It then runs through the cavernous sinus in an S-shaped curve (the carotid siphon), then it pierces the dura (beginning its subarachnoid course) and exits just medial to the anterior clinoid process and then ascends to bifurcate into anterior cerebral artery and the larger middle cerebral artery. ...

APOBEC proteins have evolved in mice and humans as potent innate defences against retroviral infections. APOBEC3G (hA3G) in humans and mouse APOBEC3 (mA3) deaminate cytidine in single-stranded DNA which ultimately results in hypermutation of newly synthesized proviral DNA. Other deaminase-independent mechanisms of inhibition have been identified, such as directly inhibiting reverse transcription. Both HIV and murine leukemia viruses (MuLVs) have evolved mechanisms to evade the action of the APOBEC proteins. HIV encodes the Vif protein which binds to hA3G and facilitates its rapid degradation through the proteasome. The mechanism(s) by which exogenous MuLVs evade mA3 inhibitory activity is unknown. Exogenous MuLVs encode a glycosylated gag protein (gGag) originating from an alternate CUG start site upstream of the AUG start site of the Gag structural polyproteins. gGag is synthesized to similar amounts as the structural Gag polyprotein in MuLV infected cells but is glycosylated in the endoplasmic
In human anatomy, the radial artery is the main artery of the lateral aspect of the forearm. The radial artery arises from the bifurcation of the brachial artery in the antecubital fossa. It runs distally on the anterior part of the forearm. There, it serves as a landmark for the division between the anterior and posterior compartments of the forearm, with the posterior compartment beginning just lateral to the artery. The artery winds laterally around the wrist, passing through the anatomical snuff box and between the heads of the first dorsal interosseous muscle. It passes anteriorly between the heads of the adductor pollicis, and becomes the deep palmar arch, which joins with the deep branch of the ulnar artery. Along its course, it is accompanied by a similarly named vein, the radial vein. The named branches of the radial artery may be divided into three groups, corresponding with the three regions in which the vessel is situated. Radial recurrent artery - arises just after the radial artery ...
Although variable, the level of the branching of the brachial artery usually occurs in the cubital fossa. Clean and identify the two large terminal branches of the brachial artery [held by forceps]. They are the radial artery that passes superficial and toward the radial side of the forearm, and the ulnar artery that passes deep to the pronator teres muscle and the flexor muscles of the forearm. As the radial artery is cleaned, attempt to identify the radial recurrent artery [held by upper forceps] which passes laterally and superiorly deep to the extensor muscles. This artery participates in the collateral circulation about the elbow. The radial and ulnar arteries also give a number of muscular branches which supply the tissues of the forearm..

Carotid atherosclerosis is a pathological thickening of the common or internal carotid intima, typically into focal areas known as plaques (or atheromata). Although atheromata can remain stable for many years, surface rupture of unstable (vulnerable) plaques leads to local thrombus formation, with subsequent embolisation to the ipsilateral ophthalmic, middle cerebral, or anterior cerebral artery territories. The resultant symptoms are ipsilateral amaurosis fugax or retinal infarction and contralateral body transient ischaemic attack (TIA) or stroke. This review discusses the risk factors, clinical presentation, investigations, and treatment options for symptomatic and asymptomatic carotid atherosclerosis.

J Neurosurg 126:1598-1605, 2017. The pathophysiological mechanisms responsible for the formation of intracranial aneurysms (IAs) remain only partially elucidated. However, current evidence suggests a genetic component. The purpose of this study was to investigate the specific anatomical variations in the arterial complex that are associated with the presence of anterior communicating artery (ACoA) aneurysms in the familial forms of IAs.. METHODS This multicenter study investigated bifurcation IAs in patients who had a sporadic ACoA IA without a family history of IA (SACAA group), in patients who had an ACoA IA with a family history of IA (FACAA group), and in their healthy first-degree relatives (HFDRs). Through the use of MR angiography (MRA) reconstructions, the symmetry of the A1 segments and the angle between the A1 and A2 segments were analyzed on 3D models for each group. These measurements were then compared among the 3 groups.. RESULTS Twenty-four patients with SACAA, 24 patients with ...

A few weeks back when I was unlucky enough to come across his show..ok I was channel surfing and I heard someone mentioning L-arginine and my biochemical ears became pointy and my fingers immediately came off the channel up button and there it was...the Dr Oz show. He was talking about L-arginine and how it can help increase the pituitarys production & secretion of Growth Hormone, which, by the way, it cannot and this was shown in studies performed years ago. I then wondered why anyone would even mention the L in front of arginine as the only arginine our bodies can utilize is the L version so its superfluous to even say L-arginine. It only suggests to me that that person just wants to look clever in the eyes of others. (As an aside the letter L is a designation of the chirality of particles, that is, bio molecules can have mirror images of one another referred to as enantiomers, the mirror image of the L is the D molecule go do an Internet search to learn more if you wish ...

Dissociated horizontal deviation after traumatic brain injury.. Korean J Ophthalmol. 2010 Dec;24(6):377-9. Authors: Lee TE, Cha DS, Koh SB, Kim SH. A 4-year-old boy visited the hospital with exotropia after brain hemorrhage caused by trauma. He had undergone decompressive craniectomy and cranioplasty 18 months prior to presentation at our hospital. An alternate prism cover test showed more than 50 prism diopters (PD) of left exotropia when he was fixing with the right eye and 30 PD of right exotropia when he was fixing with the left eye at near and far distance. On the Hirschberg test, 60 PD of left exotropia was noted in the primary position. Brain computerized tomography imaging performed 18 months prior showed hypodense changes in the right middle cerebral artery and anterior cerebral artery territories. Subfalcian herniation was also noted secondary to swelling of the right hemisphere. The patient underwent a left lateral rectus muscle recession of 7.0 mm and a left medial rectus muscle ...
The isolated cat cerebral arteries (basilar, middle cerebral, anterior cerebral, and internal carotid) were studied in vitro. ACh at low concentration (3 x 10(-8) to 3 x 10(-6) M) induced relaxation, and at high concentration (10(-5) to 3 x 10(-3) M) induced constriction of the arteries with endothelial cells. In contrast, concentration of any magnitude (10(-6) to 3 x 10(-3) M) induced constriction exclusively in arteries without endothelium. Atropine (3 x 10(-6) to 3 x 10(-5) M) blocked and physostigmine (3 x 10(-6) M) potentiated both ACh-induced relaxation and constriction. These results suggest that the relaxation induced by exogenous ACh is solely dependent on the endothelial cells and that the primary effect of the direct action of ACh on the smooth muscle cells is constriction. Transmural nerve stimulation (TNS) induced a frequency-dependent relaxation in the arteries with or without endothelium. Neither atropine nor physostigmine affected the TNS-induced dilator response in either ...

Guidelines are welcome, but have some gaps-such as perinatal stroke. Stroke care for adults has been revolutionised in recent years, possibly in association with the publication of national clinical guidelines for stroke.1 In consequence, rehabilitative care after stroke for adults is now considered the norm. Stroke is less common in children, and clinical experience and anecdotal evidence indicate that children may receive a variable quality of care. A welcome development therefore has been the publication last year of guidelines by the UK Royal College of Physicians paediatric stroke working group.2. The guidelines deal mainly with the diagnosis, investigation, and management of acute arterial ischaemic stroke in children beyond the neonatal period, covering acute presentation, management, rehabilitation, and longer term care. … ...

Doppler ultrasound was used to measure blood flow velocity in the anterior cerebral artery of six premature infants with posthaemorrhagic hydrocephalus, before and after intermittent cerebrospinal fluid (CSF) drainage, on 23 occasions. There was a significant increase in mean blood flow velocity after the drainage procedures (+5.6 cm/s, 95% confidence interval +2.9 to +8.3 cm/s), which was accompanied by a decrease in velocity waveform pulsatility. CSF pressure also fell significantly. In patients with posthaemorrhagic hydrocephalus, intermittent CSF drainage was associated with acute changes in cerebral haemodynamics.. ...
They included subjects less than 28 days old at time of diagnosis, and included both arterial and venous infarcts.

Some molecules may occur with identical atoms in the same sequence but with different spatial arrangements. These are referred to as stereoisomers. A stereoisomer that is nonsuperimposable on its mirror image is chiral, and an atom with 4 different substituents is a chiral center; the 2 mirror images are enantiomers. An equal mixture of the 2 enantiomers is racemic. Generally only 1 enantiomer is biologically active, as in the case of ibuprofen. In some cases, one enantiomer may be biologically beneficial while the other enantiomer is harmful. For example, one enantiomer of thalidomide is a beneficial drug whereas the other

Chiral molecules, however, transmit RCPL: and LCPL differently; nR (index of refraction for RCPL) is not the same as nL and one is slowed down with respect to the other; this is a result of the fact that chiral molecules have their electrons distributed in an asymmetric way so that they interact differently with RCPL than with LCPL. Furthermore, the two forms of chiral molecules (which are mirror images of one another) interact with RCPL and LCPL in opposite ways. For example, if nR , nL ==, RCPL is retarded with respect to LCPL and the plane of polarization (the orientation of E for the sum of RCPL and LCPL) will be rotated to the left. The chiral molecule with opposite hand of the one described in this example will have nR , nL and will rotate plane polarized light to the right ...

Retromastoid Craniotomy for Acoustic Tumor General Considerations As in the case with the pterional craniotomy for supratentorial parasellar lesions, the retromastoid craniotomy is the workhorse of infratentorial approaches for reaching the cerebellopontine (CP) angle and ventrolateral brainstem. Based on the definition of the extended pterional approach, lateral sphenoid wing is resected to the level of the superior orbital fissure and the roof of the orbit is flattened to provide an unobstructed operative corridor toward the subfrontal and parasellar area. Similarly, I define the extended retromastoid approach as a modification of the standard retromastoid craniotomy that includes partial removal of the bone over the sigmoid sinus. This "untethering" of the sigmoid sinus allows its lateral mobilization using retraction sutures after dural opening. This maneuver expands the lateral operative trajectory toward the CP angle while reducing the retraction on the cerebellar hemisp.... ...

In an embolic stroke, a piece of material (or embolus) travels from a distant location and lodges in the blood vessel, occluding it. The most common type of embolus is a blood clot. Because the blockage arrives from another location, the onset of embolic strokes is usually quicker than that of thrombotic strokes. As well, because of this, treatment of the stroke must also include determining the source of the embolus so as to prevent further emboli. Because a blood clot is the most common type of embolus, all of the risk factors listed above for thrombotic stroke (Virchow Triad) also apply to embolic strokes ...
