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.

Increased intracellular or extracellular fluid in brain tissue. 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).

Cerebral arterial lesions resulting from inflammatory emboli. (1/277)

In order to study the effects of septic embolism on the brain, silicone rubber emboli of various types were injected into the carotid arteries of 35 dogs. Pathologic and angiographic studies were performed to assess the resultant arterial and parenchymal lesions. Pure silicone rubber emboli (14 dogs) produced occasional intra-arterial thrombosis but no arteritis. Sterile and bacterially contaminated emboli containing a lead-chromate pigment (similar to those used in previous studies of septic embolism) (11 dogs) and pure silicone rubber emboli with transversely oriented canals (10 dogs), after brief placement in a bacterial suspension, were associated with intense inflammatory arteritis. This was accompanied by focal meningitis, subarachnoid hemorrhage, thrombosis, and cerebritis of the underlying cortex. The findings resembled those found in mycotic aneurysm. Aneurysmal dilatation was observed in one postmortem angiogram. In previous models of mycotic aneurysm, the inflammation attributed to bacterial contamination was probably due to the lead-chromate pigment used.  (+info)

Epilepsy after two different neurosurgical approaches to the treatment of ruptured intracranial aneurysm. (2/277)

One-hundred-and-fifty-two patients who underwent surgery for intracranial aneurysm were studied to determine the incidence of postoperative epilepsy in relation to the site of the aneurysm and the type of surgical approach. The overall incidence of epilepsy was 22%. Of the 116 patients treated by the intracranial approach 27.5% developed epilepsy, in contrast with only 5% of the 36 patients who had carotid artery ligation in the neck. Epilepsy occurred most frequently (35%) with middle cerebral artery aneurysms, especially if moderate or severe operative trauma was sustained and there was postoperative dysphasia.  (+info)

Arterial spasm and recovery from subarachnoid haemorrhage. (3/277)

In a series of 120 cases of subarachnoid haemorrhage due to ruptured intracranial aneurysm the occurrence of preoperative arterial spasm was found to have no effect upon the clinical outcome. After surgery, generalised arterial spasm was found to lead to an increased probability of fatality, and to an increased probability of psychological impariment among the survivors. The occurrence of spasm only in the vessels immediately adjacent to the haemorrhage did not constitute a risk to survival. However, the presence of generalised or localised spasm led to an increased risk of neurological impairment. It is suggested that the mechanisms by which postoperative arterial spasm is responsible for fatalities and for neurological impairment are distinct.  (+info)

Upregulation of MAP1B and MAP2 in the rat brain after middle cerebral artery occlusion: effect of age. (4/277)

Although stroke in humans usually afflicts the elderly, most experimental studies on the nature of cerebral ischemia have used young animals. This is especially important when studying restorative processes that are age dependent. To explore the potential of older animals to initiate regenerative processes after cerebral ischemia, the authors studied the expression of the juvenile-specific cytoskeletal protein, microtubule-associated protein (MAP) 1B, and the adult-specific protein, MAP2, in male Sprague-Dawley rats at 3 months and 20 months of age. The levels of MAP1B and MAP2 transcripts and the corresponding proteins declined with increasing age in the hippocampus. In the cortex, the levels of the transcripts did not change significantly with age, but the morphologic features of immunostained fibers were clearly affected by age; that is, cortical MAP1B fibers became thicker, and MAP2 fibers, more diffuse, in aged rats. Focal cerebral ischemia, produced by reversible occlusion of the right middle cerebral artery, resulted in a large decrease in the expression of both MAP1B and MAP2 in the infarct core at the messenger ribonucleic acid and protein levels. However, at 1 week after the stroke, there was vigorous expression of MAP1B and its messenger ribonucleic acid, as well as MAP2 protein, in the border zone adjacent to the infarct of 3-month-old and 20 month-old male Sprague-Dawley rats. The upregulation of these key cytologic elements generally was diminished in aged rats compared with young animals, although the morphologic features of fibers in the infarct border zone were similar in both age groups. These results suggest that the regenerative potential of the aged rat brain appears to be competent, although attenuated, at least with respect to MAP1B and MAP2 expression up to 20 months of age.  (+info)

Transluminal angioplasty for middle cerebral artery stenosis in patients with acute ischemic stroke. (5/277)

BACKGROUND AND PURPOSE: Precutaneous transluminal angioplasty (PTA) is currently performed to treat supraaortic atherosclerotic lesions. Our purpose was to evaluate the safety and efficacy of PTA for middle cerebral artery (MCA) stenosis in patients with acute ischemic stroke. METHODS: We performed PTA with the use of a microballoon (2-2.5 mm in diameter and 10-13 mm in length) in 10 consecutive patients (mean age, 48 years) who met the following criteria: high-grade M1 stenosis (> 70%) and mild neurologic deficits (NIH stroke scale < 4) and/or recurrent transient ischemic attacks (TIAs) resistant to anticoagulation, or a large area of hypoperfusion in the MCA territory on brain perfusion SPECT scans. During follow-up, we administered antiplatelet agents and evaluated the status of restenosis by angiography (n = 2), brain perfusion SPECT (n = 4), and/or transcranial Doppler sonography (TCD) (n = 7). RESULTS: Stenotic arteries were successfully dilated in nine of 10 patients. Angioplasty failed in one patient because the balloon could not pass through the tortuous cavernous internal carotid artery. None of the patients experienced either peri- or postangioplasty complications. Residual stenosis was less than 50%, and clinical improvement, including elimination of TIAs in four patients who had suffered resistant TIAs, was observed in all patients; improvement of the cerebral perfusion was also noted in two patients with a large hypoperfusion area in the MCA territory. The average follow-up period was 11 months (range, 2 to 36 months). None experienced recurrent stroke during the follow-up period. TCD revealed decreased flow velocity of the MCA after angioplasty in seven patients. CONCLUSION: PTA of the proximal portion of the MCA seems to be a safe and effective therapeutic technique for the prevention of secondary ischemic stroke.  (+info)

Various patterns of perfusion-weighted MR imaging and MR angiographic findings in hyperacute ischemic stroke. (6/277)

BACKGROUND AND PURPOSE: Various clinical subtypes of patients presenting with sudden-onset ischemic stroke have been recognized, but classification of those types is not simple. We identified various patterns of perfusion-weighted MR imaging and MR angiographic findings in hyperacute ischemic stroke with relation to clinical outcomes. METHODS: Twelve patients with symptoms of acute ischemic stroke due to middle cerebral artery occlusion underwent perfusion-weighted MR imaging and MR angiography within 6 hours after the onset of symptoms. Perfusion-weighted imaging was performed with a conventional dynamic contrast-enhanced T2*-weighted sequence, and cerebral blood volume (CBV) maps were then created. CBV maps and MR angiographic findings were compared with 99mTc-HMPAO brain SPECT scans, short-term outcomes, and follow-up imaging findings. RESULTS: The combined CBV and MR angiographic findings were classified into three patterns: arterial occlusion and decreased CBV (n = 8), arterial occlusion and increased CBV (n = 2), and no arterial occlusion and normal CBV (n = 2). These three patterns were strongly related to SPECT findings, short-term outcomes, and follow-up imaging findings. Perfusion on SPECT decreased markedly in the affected regions in all patients with the first pattern, decreased slightly in the second pattern, and was normal in the third pattern. Symptoms were not significantly changed at 24 hours after onset in any of the patients with the first pattern, but resolved completely in all patients with the latter two patterns. Follow-up imaging showed large infarctions in all patients with the first pattern. Initially, no infarction was seen in the second pattern, but watershed infarction developed later in one of these patients. CONCLUSION: Hyperacute ischemic stroke may be differentiated into three imaging patterns with different clinical outcomes. The combined use of perfusion-weighted MR imaging and MR angiography may play a substantial role in guiding the choice of treatment of this disease.  (+info)

Carotid artery tandem lesions: frequency of angiographic detection and consequences for endarterectomy. (7/277)

BACKGROUND AND PURPOSE: Several prospective trials have shown that ischemic stroke can be prevented by performing an endarterectomy in patients with high-grade carotid stenosis. Our purpose was to ascertain the frequency of carotid artery tandem lesions and to determine whether their presence alters the surgeon's decision to perform an endarterectomy. METHODS: We retrospectively reviewed the cerebral angiograms obtained between January 1994 and June 1996 in 853 patients with carotid occlusive disease. Studies were analyzed for the presence of internal carotid artery (ICA) stenosis as well as for tandem lesions (defined as > or = 50% diameter stenosis) within the common carotid artery, carotid siphon, or proximal intracranial arteries. The frequency of intracranial saccular aneurysms was determined. RESULTS: Six hundred seventy-two of the 853 patients had a carotid bifurcation stenosis of 70% or greater or underwent an endarterectomy. Of these, a carotid siphon stenosis of 50% or greater was noted in 65 patients (9.7%) and was ipsilateral to an ICA stenosis in 37 patients (5.5%). A common carotid stenosis was present in 29 patients (4.3%), ipsilateral to an ICA stenosis in 14 patients (2.1%). A stenosis of 50% or greater within the proximal intracranial circulation was present in 28 patients (4.2%), ipsilateral to an ICA stenosis in 15 patients (2.2 %). Four patients had tandem stenoses at more than one site. Tandem stenoses in the siphon or intracranial segments were noted in 13.5% with a bifurcation stenosis and in 8.8% of those with no bifurcation stenosis. Endarterectomy was performed in 48 of the 66 patients with tandem stenotic lesions. CONCLUSION: The presence of a tandem lesion infrequently alters the surgeon's decision to perform an endarterectomy. However, the importance of detecting tandem stenoses cannot be underestimated, since they may have important implications for long-term medical management in symptomatic patients.  (+info)

Cerebral hemodynamics in relation to patterns of collateral flow. (8/277)

BACKGROUND AND PURPOSE: We sought to investigate the relation between collateral flow via different pathways and hemodynamic parameters measured by dynamic susceptibility contrast-enhanced MRI in patients with severe carotid artery disease. METHODS: Dynamic susceptibility contrast-enhanced MRI was performed in 66 patients and 33 control subjects. Patients had severe stenosis (>70%, n=12), unilateral occlusion (n=38), or bilateral occlusion (n=16) of the internal carotid artery (ICA). Cerebripetal flow and collateral flow via the circle of Willis were investigated with MR angiography. Collateral flow via the ophthalmic artery was investigated with transcranial Doppler sonography. RESULTS: Patients with ICA stenosis had well-preserved cerebral perfusion and were in general not dependent on collateral supply. Patients with unilateral ICA occlusion had impaired cerebral perfusion. However, appearance time, peak time, and mean transit time in white matter were less increased in patients with than in patients without collateral flow via the circle of Willis (P<0.05). Furthermore, patients with collateral flow via both anterior and posterior communicating arteries had less increased regional cerebral blood volume than patients with collateral flow via the posterior communicating artery only (P<0.05). Patients with bilateral ICA occlusion had severely compromised hemodynamic status despite recruitment of collateral supply. CONCLUSIONS: In patients with unilateral ICA occlusion, the pattern of collateral supply has significant influence on hemodynamic status. Collateral flow via the anterior communicating artery is a sign of well-preserved hemodynamic status, whereas no collateral flow via the circle of Willis or flow via only the posterior communicating artery is a sign of deteriorated cerebral perfusion.  (+info)

Until recently, cerebral arteriopathy due to heterozygous mutations of the ACTA2 gene was considered a variant of moyamoya disease. However, radiographic analysis of patients with these mutations reveals a distinctive angiographic appearance from that seen in moyamoya disease. Several heterozygous missense ACTA2 mutations have been implicated in the development of this distinct cerebrovascular entity; however, the penetrance and systemic manifestations of these mutations vary based on the location of the amino acid replacement within the α-smooth muscle actin protein. The severity of the phenotype may also differ among patients within a single mutation type. There is limited literature on the safety and efficacy of revascularization procedures for ACTA2 arteriopathy, which have been limited to those patients with known Arg179His mutations. The authors provide a review of the breadth of mutations within the ACTA2 literature and report a case of two siblings with de novo ACTA2 Arg258Cys mutations ...
Radiation therapy can cause cerebral arteriopahty, resulting in ischemic stroke. We document late-delayed cerebral arteriopathy by high-resolution magnetic resonance imaging (HR-MRI) in a middle aged man who had cranial irradiation 19 years earlier. A 45-year-old man was diagnosed with frontal lobe glioma 19 years ago and was treated with radiation after surgical resection. He was admitted to our hospital with an acute cerebral infarction in November 8, 2017. Traditional MRI examination and HR-MRI (sagittal, reconstruction of coronal and axial) were performed at admission. He was treated with prednisone (30 mg/day) and clinical symptoms disappeared after 3 months by telephone follow-up. Our patient complained of dizziness and blurred vision and traditional MRI examination indicated acute ischemic stroke in temporal lobe and occipital lobe and microbleeds. In order to define the exact mechanism of stroke, blood tests, auto-immune screening and thrombophilia were performed and results were normal.

The instability of carotid and coronary plaques has been reported to be associated with acute coronary syndrome, strokes and other cerebrovascular events. Therefore, recognition of the tissue characteristics of carotid and coronary plaques is important to understand and prevent coronary and cerebral artery disease. Recently, an ultrasound integrated backscatter (IB) technique has been developed. The ultrasound IB power ratio is a function of the difference in acoustic characteristic impedance between the medium and target tissue, and the acoustic characteristic impedance is determined by the density of tissue multiplied by the speed of sound. This concept allows for tissue characterization of carotid and coronary plaques for risk stratification of patients with coronary and cerebral artery disease. Two- and three-dimensional IB color-coded maps for the evaluation of tissue components consist of four major components: fibrous, dense fibrosis, lipid pool and calcification. Although several ultrasound

Metabolomics is a large-scale approach to monitoring as many as possible of the compounds involved in cellular processes in a single assay to derive metabolic profiles. Compared with genomics or proteomics, metabolomics reflects changes in phenotype and therefore function. Collection of exhaled breath condensate (EBC) is a newly developed, noninvasive method that may allow clinicians and researchers to assess biochemical profiles in the alveolar lining fluid. The aims of this study are: (1)Collecting and metabolomic profiling of the EBCs from patients with COPD/bronchiectasis; (2) Comparing the profiles of these patients obtained during stable and acute exacerbation periods; (3) Comparing the profiles of these patients with and without Pseudomonas colonization/infection; (4) Correlation of EBC metabolomic profiles with clinical phenotypes, severity and outcomes of these patients ...
This is the first case report of a CADASIL patient with MCA stenosis who underwent STA-MCA bypass to increase cerebral perfusion in the localized ischemic area. In CADASIL, reductions in both CBF and CVR occur in white matter showing T2-hyperintensity. It has been suggested that the degeneration of vascular smooth muscle cells causes arteriopathy, which leads to cerebral hypoperfusion and impaired autoregulation (Chabriat et al. 2000; Huang et al. 2010; Singhal and Markus 2005; van den Boom et al. 2003). Interestingly, the white-matter hyperintensity in the temporal lobe was found predominant in the left side in this case. This asymmetry of white-matter hyperintensity is very unusual rare in CADASIL, since it would suggest that these lesions do not originate from ischemia, but edema instead. The lower extent observed in the most hypoperfused temporal lobe further support that these lesions are not related to ischemia but mat actually result from edema with blood brain barrier dysfunction. ...
There are many reports about the association of coronary artery disease (CAD) and cerebral artery stenosis (CAS), which had been proved to induce stroke and cognition decline after the revascularization including coronary bypass surgery (CABG) or percutaneous coronary intervention. Perfusion defect on nuclear brain scan is also noted to correlate with these neurological complications. On the other hand, the perioperative arrhythmia and following cerebral embolism was also attributed to be one factor inducing such neurological hazards.. In the patients with coexistent CAD and CAS (1st group), and also the patients scheduled for CABG or percutaneous coronary intervention (PCI) (2nd group), we, the researchers at Far Eastern Memorial Hospital, attempted to integrate all the parameters mention above, including angiography of coronary and cerebral system, quantitative analysis of nuclear brain scan, biochemical profile, and signals of a new ambulatory device which could record the electrocardiograph ...

Reversible cerebral vasoconstriction syndrome (RCVS) is a fairly recently described constellation of clinical and radiological features: sudden, severe (thunderclap) headache; transient, multifocal, segmental vasoconstriction of cerebral arteries lasting several weeks to months; and focal neurological symptoms, sometimes with stroke. The features of what is now called RCVS have been repeatedly recognized, especially since an influential early report by Drs Call and Fleming et al1 published in 1988. A similar syndrome has attracted many different names, depending on whether patients present to specialists in headache, obstetrics, or neurology. These include thunderclap headache with vasospasm, migrainous vasospasm (or crash migraine), migrainous angiitis, drug-induced angiitis, postpartum angiopathy, and benign angiopathy of the central nervous system. The label RCVS is an attempt to unify these various descriptions of a distinct clinico-radiological pattern. Nevertheless, there remains ...
BACKGROUND AND AIM OF THE STUDY: Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by severe thunderclap headache, with or without associated neurological symptoms and neuroimaging findings of reversible vasoconstriction of cerebral arteries. Puerperium is a recognized precipitant, but the incidence of puerperal RCVS is unknown. We conducted a prospective study to assess incidence, risk factors and clinical features of RCVS. MATERIAL AND METHOD: Nine-hundred consecutive puerperae were prospectively enrolled within three days of delivery. Past medical history, basal demographic, anthropometric and biological variables were recorded. Transcranial Colour Coded Sonography (TCCS) was performed to assess early signs of vasospasm in brain vessels. A structured telephone interview was planned in all subjects one month postdelivery. RESULTS: Thunderclap headache was recorded in 8 subjects (0.9%) on the first visit. At the one month follow-up interview 27 more patients reported having had at

Reversible cerebral vasoconstriction syndrome (RCVS, sometimes called Call-Fleming syndrome) is a disease characterized by a weeks-long course of thunderclap headaches, sometimes focal neurologic signs, and occasionally seizures. Symptoms are thought to arise from transient abnormalities in the blood vessels of the brain. In some cases, it may be associated with childbirth, vasoactive or illicit drug use, or complications of pregnancy. For the vast majority of patients, all symptoms disappear on their own within three weeks. Deficits persist in a small minority of patients, with severe complications or death being very rare. Because symptoms resemble a variety of life-threatening conditions, differential diagnosis is necessary. The key symptom of RCVS is recurrent thunderclap headaches, which over 95% of patients experience. In two-thirds of cases, it is the only symptom. These headaches are typically bilateral, very severe and peak in intensity within a minute. They may last from minutes to ...

RCVS is a cerebrovascular disorder that can be occur as late as 3 weeks after an uncomplicated pregnancy, characteristic neuroimaging finding accompanied by severe and acute headache are important key features to consider RCVS diagnosis.. Here were present a 39-year-old woman, presented with headache and subsequent right hemiparesis 3 weeks after abortion. First brain CT scan was unremarkable. Brain CT angiography showed multiple segmental stenosis and at later scans, she developed sub arachnid hemorrhage (SAH) which is a pathognomonic feature of RCVS. She was treated with calcium channel blocker and headache relieved and hemiparesis was improved. Final diagnosis was made based on normal trans-cranial Doppler (TCD) study after 4 weeks of symptoms onset.. ...
Background and purpose: Atherosclerotic stenosis of major intracranial arteries accounts for 5 to 10% of all causes of stroke. The Warfarin versus Aspirin Symptomatic Intracranial Disease (WASID) Study has demonstrated stroke onset in 5 among 100 patients with asymptomatic intracranial arterial stenosis (AIAS) during the follow-up period of 1.8 years. However, there are no prospective studies of intracranial stenosis in healthy subjects with a longer follow-up period. We conducted a 7-years longitudinal study in healthy subjects with AIAS to examine its risk factors and prognosis.. Methods: We performed a prospective study on 3,155 neurologically normal subjects without history of stroke (1724 men, 1431 woman, mean age of 59). They were followed up with the mean interval of 83 months to obtain information about their stroke event with a questionnaire by mail or telephone interview and inquiry to the relevant medical facilities. AIAS were assessed on MRA at the time of first visit for all ...

Specific patterns of white matter hyperintensities in the brain may guide diagnosis of reversible cerebral vasoconstriction syndrome, a disorder predominantly characterized by severe thunderclap headaches.
Strong correlations between plasma lipoprotein concentrations and the risk of stroke have never been clearly established. Unlike coronary heart disease, there is no significant direct relation between an increased risk of stroke and increased plasma total cholesterol or low density lipoprotein (LDL) cholesterol; nor is there an inverse relation with high density lipoprotein (HDL) cholesterol.1 Indeed, an inverse relation exists between total cholesterol concentrations and cerebral haemorrhage.2. The reasons for this weak or absent relation are several. The most compelling is that virtually all coronary heart disease can be ascribed to coronary atheroma, whereas less than half the incidence of stroke is due to large vessel atheroma. Non-atheromatous causes such as cardiac arrhythmias, small cerebral artery disease, and cortical degeneration are responsible for most of the rest. Another is that, in general, coronary deaths occur at a younger age than strokes, so the population with raised plasma ...

Neuroborreliosis affects the nervous system after systemic infection with the spirochete Borrelia burgdorferi. Previously, cerebral vasculitis has been regarded as an extremely rare complication of neuroborreliosis. The data on the long-term outcome in patients with cerebral vasculitis due to neuroborreliosis are limited. The objective of this study was to perform a longitudinal analysis of cases of neuroborreliosis-associated cerebral vasculitis. We recruited all patients (n = 11) diagnosed with neuroborreliosis-associated in three neurological departments in an East German region. Inclusion criteria were sudden neurological deficits, magnetic resonance (MR) imaging findings that conform to cerebral ischemia or brain infarction, intrathecal synthesis of borrelia-specific antibodies, and non-atherosclerotic pathology of brain supplying arteries. Vasculitic changes were detected by digital subtraction angiography, MR angiography and/or transcranial Doppler ultrasound. Outcomes were measured by ...

© Cambridge University Press 2014. Introduction: Cerebral ischemia is thought to be an important disease mechanism in cerebral small vessel disease (SVD). It has been hypothesized that acute ischemia in the territory of the perforating artery results in lacunar stroke, while chronic ischemia occurring in the distal territories of the perforating arteries results in changes to cerebral white-matter, known as leukoaraiosis. The spatial pattern of leukoaraiosis, with changes first occurring in the brain regions furthest from the origin of the perforating arteries, would be consistent with disease occurring due to hypoperfusion. This has led to the suggestion that cerebral blood flow (CBF) is reduced in SVD, and many studies have been performed to investigate this issue. In addition, cerebral arteriopathy underlying SVD may also impair the ability of small cerebral vessels to vasodilate, leading to problems maintaining perfusion in response to drops in blood pressure and perfusion pressure. Impairments of
The purpose of the study was to highlight the acute motor reflex adaptation and to deepen functional deficits following a middle cerebral artery occlusion-reperfusion (MCAO-r). Thirty-six Sprague-Dawley rats were included in this study. The middle cerebral artery occlusion (MCAO; 120 min) was performed on 16 rats studied at 1 and 7 days, respectively (MCAO-D1 and MCAO-D7, n = 8 for each group). The other animals were divided into 3 groups: SHAM-D1 (n = 6), SHAM-D7 (n = 6) and Control (n = 8). Rats performed 4 behavioral tests (the elevated body swing test, the beam balance test, the ladder-climbing test and the forelimb grip force) before the surgery and daily after MCAO-r. H-reflex on triceps brachii was measured before and after isometric exercise. Infarction size and cerebral edema were respectively assessed by histological (Cresyl violet) and MRI measurements at the same time points than H-reflex recordings. Animals with cerebral ischemia showed persistent functional deficits during the ...
Reversible Cerebral Vasoconstriction Syndromes (RCVS) comprises a group of diverse conditions, all characterized by spasm of the brain vessels. The main symptom of RCVS is sudden, severe headaches. Strokes or bleeding into the brain may or may not be present. RCVS was previously named benign angiopathy of the central nervous system (BACNS) but the term was recently changed to include other similar disorders.. RCVS is a major mimic of central nervous system vasculitis and should be distinguished from it given the difference in the treatment and the outlook between the two disorders.. Abnormality in the control of brain blood vessel pressure is believed to be the critical element in the pathophysiology of RCVS. The alteration in vascular tone may be spontaneous or evoked by various exogenous or endogenous factors. There is no evidence of vasculitic changes in the brain tissue in RCVS.. It is essential for clinicians evaluating patients for CNS vasculitis to be aware of RCVS and to distinguish it ...
BACKGROUND AND PURPOSE: Elevated OEF is a surrogate for misery perfusion. Our aim was to detect misery perfusion in patients with unilateral steno-occlusive disease of the ICA or MCA by using T2*-based MR imaging and to determine the relationship between brain ischemia and OEF.. MATERIALS AND METHODS: Twenty-three patients with unilateral steno-occlusive disease of the ICA or MCA and 8 healthy volunteers were included in this study. Hemodynamic information was obtained in all subjects by MR imaging. Three regions of interest were placed in the anterior, middle, and posterior parts of the brain bilaterally to measure the OEF and CBF values, The OEFs of the regions of interest in the hemispheres ipsilateral and contralateral to the vascular lesions were compared. Brain regions with OEF greater than that in controls were determined as misery perfusion in patients. The association of vascular lesions, rCBF, and the presence of territory infarction with elevated OEF was investigated.. RESULTS: There ...

Female gender, which is abolished following ovariectomy and reproductive senescence, is associated with improved outcome following cerebral stroke. Estrogen replacement partially restores this benefit of the female gender but the effect of progesterone in hormone-deficient animals is currently unknown. We evaluated various outcomes following middle cerebral artery occlusion (MCAO) in ovariectomised female mice, with a physiologically relevant restoration of progesterone levels. Ovariectomised female mice had significantly elevated plasma (P=,0.05) and brain progesterone levels (P=,0.01) following implantation of a 21-day release pellet (50mg) compared with mice that received placebo implants 7 days prior to undergoing 60 min MCAO. Assessment of well-being (body weight recovery) and neurological score at 24h and 48h post-MCAO indicated that MCAO significantly worsened outcome compared with sham-operated mice but progesterone had no effect. MCAO resulted in a substantial lesion formation and a ...
A recent large series7 found specific vasculopathies in 18% of pediatric ischemic strokes. We identified recognizable vasculopathies in almost 25% of our patients with arterial ischemic stroke. This percentage may underestimate their prevalence because not all patients in our series underwent vascular imaging. These findings underline the importance of vascular investigation in all arterial ischemic strokes in children. Moyamoya was the most frequent recognizable vasculopathy in our cases of ischemic stroke. Although the exact pathophysiologic mechanism of moyamoya remains unknown, it has been associated with many conditions, including trisomy 21 and congenital heart disease.15,16 The association of moyamoya with lupus anticoagulant17 or with a significantly elevated blood level of IgG aCLA18,19 also has been reported, albeit rarely. We report here two more cases of moyamoya associated with aCLA and arterial ischemic stroke. Surprisingly, in our series, aCLA was found in 2 of 6 patients with ...
When blood flow to part of the brain is blocked or reduced, the brain tissue is impacted and brain cells begin to die. This is known as a stroke. When an infant or child under the age of 18 has a stroke, it is known as a pediatric stroke.
