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).

Intracranial arteriovenous malformations. Observations after experience with computerised tomography. (1/3145)

Thirty-six patients with angiographically confirmed intracranial arteriovenous malformations have had computerised tomographic scans performed as part of their investigation. This study demonstrates the incidence of haematoma formation after haemorrhage, the frequency of calcification not visible on plain radiographs, and describes the possible causes for a complicating hydrocephalus.

Intracerebral hemorrhage in young people: analysis of risk factors, location, causes, and prognosis. (2/3145)

BACKGROUND AND PURPOSE: The frequency of intracerebral hemorrhages (ICHs) in people aged 31 years (odds ratio, 3.48), and those with ICH that resulted from arteriovenous malformations were aged <20 years (odds ratio, 2.80). The final outcome was considered favorable in 60%. CONCLUSIONS: ICHs in young people are mainly lobar in location and result from vascular malformation. Hypertension causes most cases in which the ICH is located in the basal ganglia. Mortality and morbidity in the acute phase are low and are related to hypertension as the cause of ICH.  (+info)

Increased platelet activation in the chronic phase after cerebral ischemia and intracerebral hemorrhage. (3/3145)

BACKGROUND AND PURPOSE: Enhanced thromboxane (TX) biosynthesis has previously been reported in the acute phase after ischemic stroke. We investigated whether enhanced urinary excretion of 11-dehydro-TXB2, a noninvasive index of platelet activation, was present in the chronic phase after a transient ischemic attack (TIA) or stroke, including intracerebral hemorrhage. METHODS: We obtained a single urinary sample from 92 patients between 3 and 9 months after onset of stroke or TIA. The urinary excretion of the major enzymatic metabolite of TXA2, 11-dehydro-TXB2, was measured by a previously validated radioimmunoassay. The excretion rates were compared with those of 20 control patients with nonvascular neurological diseases. RESULTS: Urinary 11-dehydro-TXB2 averaged 294+/-139, 413+/-419, and 557+/-432 pmol/mmol creatinine for patients with TIA, ischemic stroke, and intracerebral hemorrhage, respectively; the values were higher in all subgroups (P<0.01) than that in control patients (119+/-66 pmol/mmol). Increased 11-dehydro-TXB2 excretion was present in 59% of all patients, in 60% (P<0.001) of patients with TIA, in 56% (P<0.001) of patients with ischemic stroke, and in 73% (P<0.001) of patients with intracerebral hemorrhage. Atrial fibrillation, no aspirin use, and severity of symptoms at follow-up contributed independently to the level of 11-dehydro-TXB2 excretion in a multiple linear regression analysis. CONCLUSIONS: Platelet activation is often present in patients in the chronic phase after stroke, including those with intracerebral hemorrhage. Persistent platelet activation, which is associated with atrial fibrillation and poor stroke outcome, can be substantially suppressed by aspirin treatment.  (+info)

Intensive care management of stroke patients. (4/3145)

Two hundred eighty patients were admitted to an intensive care stroke unit over a one-year period. Subsequent investigation indicated that only 199 of these patients actually had cerebral ischemic or hemorrhagic lesions, 10 had other cerebrovascular lesions, and the remaining 71 patients had unrelated diseases, predominantly seizures. Detailed analysis of 103 stroke patients revealed an overall incidence of 59% hypertension, and 72% had hypertensive, ischemic or valvular heart disease. Fifty percent of the patients had various cardiac arrhythmias, some of which were responsible for the acute cerebrovascular lesion. Fourteen patients died during the acute phase, 11 from apparently irreversible cerebral selling, mainly due to cerebral hemorrhage. Secondary complications such as pneumonia, pulmonary embolism, pressure sores and urinary infection were almost nonexistent, but beneficial effects on the primary cerebral lesions were more difficult to demonstrate.  (+info)

A prospective study of cerebrovascular disease in Japanese rural communities, Akabane and Asahi. Part 1: evaluation of risk factors in the occurrence of cerebral hemorrhage and thrombosis. (5/3145)

An epidemiological study of cerebrovascular disease in Akabane and Asahi, Japan, was made. (These cities are located near Nagoy, Japan.) The study population included 4,737 men and women aged 40 to 79 at the time of entry into the study. There were 4,186 persons who were examined and, of these, 264 cases of cerebrovascular attacks were observed between 1964 and 1970. The incidence rate of stroke in those persons not responding to the survey was 15.9 times higher than in those persons examined according to person-year observation in Akabane. The risk factors for cerebral hemorrhage and thrombosis were evaluated by age-adjusted and sex-adjusted relative risks. The predisposing factors to cerebral hemorrhage appeared to be high blood pressure, high left R wave, ST depression, T abnormality, capillary fragility counts, previous medical history of stroke and albuminuria. For cerebral thrombosis, the predisposing factors appeared to be high blood pressure, ST depression and funduscopic sclerotic findings, and those factors assumed to be significant were glycosuria and smoking habits. Ocular funduscopic abnormality was the most prominent risk factor for cerebral thrombosis, while high blood pressure and ECG abnormalities were highly related to cerebral hemorrhage. It was suggested that those subjects with a relatively higher blood pressure may have a higher relative risk of cerebral hemorrhage than those with a lower (normal range) blood pressure. A previous or family history of stroke also appeared significantly related to cerebral hemorrhage.  (+info)

Primary non-traumatic intracranial hemorrhage. A municipal emergency hospital viewpoint. (6/3145)

The devastating natural history of 138 consecutive admissions for non-traumatic intracranial hemorrhage to a major emergency care municipal hospital is reviewed. Sixty-four percent of the patients had demonstrable intracranial hematomas while 36% had mainly subarachnoid hemorrhage. Hypertension was a related condition in 43% of the parenchymal hematoma patients, while proved aneurysms accounted for 74% of the subarachnoid hemorrhage patients. There was only a 14% survivorship for patients requiring emergent surgery. All operated hematoma patients survived delayed surgery with improved level of responsiveness. The overall mortality was 74% for intracranial hematoma patients and 58% for aneurysm-caused subarachnoid hemorrhage patients.  (+info)

Angiographical extravasation of contrast medium in hemorrhagic infarction. Case report. (7/3145)

Leakage of the contrast medium was noted on angiograms of a patient whose autopsied brain disclosed typical pathological findings of hemorrhagic infarction. The case was a 63-year old woman with mitral valve failure, who suddenly had loss of consciousness and right-sided hemiplegia. The left carotid angiography performed six hours after onset demonstrated middle cerebral arterial axis occlusion, and the second angiography performed three days after onset displayed recanalization of the initially occluded artery as well as extravasation of the contrast medium. Fourteen days after onset the patient died and an autopsy was performed. The brain demonstrated perivascular punctate hemorrhages in the area supplied by the middle cerebral artery, and neither hematoma nor microaneurysm was disclosed pathologically. A short discussion is given on the possible relationship between recanalization and hemorrhagic infarction. The clinical assessment of hemorrhagic infarction has not been established successfully.  (+info)

Pure apraxic agraphia with abnormal writing stroke sequences: report of a Japanese patient with a left superior parietal haemorrhage. (8/3145)

A 67 year old Japanese male patient had pure agraphia after a haemorrhage in the left superior parietal lobule. He developed difficulty in letter formation but showed no linguistic errors, consistent with the criteria of apraxic agraphia. He manifested a selective disorder of sequencing writing strokes, although he was able to orally state the correct sequences. The patient's complete recovery after 1 month, without new learning, showed that he had manifested a selective disorder of writing stroke sequences. These findings indicate that the final stage of the execution of writing according to acquired sequential memory shown as a stroke sequence can be selectively disturbed, and should be considered to be distinct from the ability of character imagery and the knowledge of the writing stroke sequence itself. This case also indicates that the left superior parietal lobule plays an important part in the execution of writing.  (+info)

Abstract Background Neuroendocrine changes have been reported after ischemic stroke, subarachnoid hemorrhage, and brain trauma. As there are no corresponding data in patients with intracerebral hemorrhage (ICH) we analyzed various neuroendocrine parameters to investigate possible alterations in hormone profiles of patients with ICH.. Methods Twenty patients with ICH were prospectively enrolled in the study. Patients were a priori parted into two groups: Ten non-ventilated patients treated on the stroke-unit (hemorrhage volumes ,20 ml, small ICH), and 10 ventilated patients treated on the neurocritical care unit (hematoma volumes ,20 ml with possible additional ventricular involvement (large ICH). Neuroendocrine parameters were compared between both groups referring to reference values. The following parameters were obtained over a period of 9 days in 20 patients with spontaneous supratentorial ICH: thyrotropin, free thiiodothyronine and thyroxine, human growth hormone, insulin-like growth ...

Methods Clinical and demographic data were extracted from the charts of 182 consecutive black Americans admitted for SICH diagnosed by clinical criteria and initial CT scan. Hemorrhage volumes were calculated from admission CT scans by a computerized method. Univariate and multiple logistic regression analyses were performed to determine independent predictors of early deterioration ...
Background: Current American Heart Association guidelines for targeted blood pressure management in spontaneous intracerebral hemorrhage (ICH), published in 2010, suggest a target mean arterial pressure of less than 110 or a blood pressure of less than 160/90 in patients without elevated intracranial pressure. These guidelines acknowledge that these recommendations have been based on incomplete efficacy evidence. A lower level recommendation was given for reducing target blood pressure to a systolic of 140, based on the INTERACT trial published in 2008. The INTERACT2 trial, published in May 2013, has been interpreted to establish the safety of rapid blood pressure lowering to 140 systolic.. Purpose: To determine the current level of adoption by stroke centers of lower targets for blood pressure in patients with spontaneous intracerebral hemorrhage, and whether these targets have changed in 2013.. Methods: We developed a web-based survey that was distributed via email and professional groups to ...

TY - JOUR. T1 - Platelet Count and Function in Spontaneous Intracerebral Hemorrhage. AU - Ziai, Wendy C.. AU - Torbey, Michel T.. AU - Kickler, Thomas S.. AU - Oh, Sangjin. AU - Bhardwaj, Anish. AU - Wityk, Robert J.. PY - 2003/7. Y1 - 2003/7. N2 - Impaired platelet function has been associated with an increased propensity for intracerebral hemorrhage (ICH). The role of platelet count and dysfunction in spontaneous ICH (SICH) is poorly understood. We tested the hypotheses that patients with SICH have subtle platelet dysfunction associated with ICH progression and larger ICH size. In a retrospective case series, we compared platelet counts in patients with SICH with age-matched controls with neuromuscular disorders admitted to a Neurosciences Critical Care Unit (NCCU). In a subset of patients, platelet function was measured within one week of ICH. Computerized tomography (CT) scans were performed within 24 hours of the event and ICH volume determined by the ABC/2 method. Comparison of 43 patients ...
Background and rationale Acute intracerebral haemorrhage (ICH) results from rupture of cerebral vasculature leading to bleeding into the cerebral parenchyma. ICH represents 10-50% of stroke, depending on the population studied, is associated with significant morbidity and mortality, and has limited treatment options. The INTERACT2 trial was designed to assess the role of blood pressure lowering therapy in intracerebral haemorrhage. Guideline therapy (target systolic blood pressure [SBP] ,180 mmHg) was compared against intensive lowering (SBP ,140 mmHg). The outcomes assessed in this trial were death or major disability (according to the modified Rankin scale at 90 days) following ICH. Hyperglycaemia has been widely studied in acute illnesses as myocardial infarction, ischaemic stroke, traumatic brain injury and ICH, and is associated with adverse outcomes. The incidence of hyperglycaemia in the acute phase is due to a combination of factors: diabetic pathophysiology and stress hyperglycaemia. ...
Background and Purpose-Recently COL4A1, a gene encoding the type IV collagen a1 chain, has been found to be involved in families with autosomal-dominant porencephaly and infantile hemiparesis. In addition to neonatal stroke, some family members had experienced, during adulthood, spontaneous intracerebral hemorrhages (ICHs) and leukoencephalopathy, suggestive of underlying small-vessel disease of the brain. We now report a patient with sporadic, recurrent ICHs and a novel COL4A1 mutation.
BACKGROUND AND OBJECTIVE: Acute hypertensive response, defined as systolic blood pressure (SBP) 140 mmHg or more within 24 h of onset, is frequently observed in hemorrhagic stroke patients. Although catecholamine surge is pivotal in its pathogenesis, few studies have evaluated the relationship between admission SBP and plasma catecholamine levels.. PATIENTS AND METHODS: A prospective observational study was carried out to investigate potential differences in the acute hypertensive reaction between subarachnoid hemorrhage (SAH) and spontaneous intracerebral hemorrhage (SICH) by analyzing 200 SAH and 200 SICH patients. In each category, patients were quadrichotomized on the basis of their SBPs in emergency department: less than 140 mmHg, 140-184 mmHg, 185-219 mmHg, and 220 mmHg or more. The plasma catecholamine levels were compared among the four groups. Furthermore, multivariate regression analyses were carried out to identify variables correlated with hypertensive emergency (SBP≥185 ...
Twenty-two patients who had evidence of spontaneous intracerebral hemorrhage in brain computerized tomographic(CT) scan specially with small vascular malformations who were angiographically verified and unknown causes, were reviewed. The majority of patients were in first and second decades of life. The duration of symptoms from onset to admission showed relatively short in verified cases and even distributed from 1 day to 1 month in unknown cases. The most common presenting symptoms and signs were headache and papilledema in unknown cases. In brain CT scan, variable findings were seen as hematoma with surrounding eidence of vascular anomaly, hematoma only and blood-fluid level in verified cases, and tumor-like findings in unknown cases. The most common site of hematoma were parietal and occipital lobes in verified cases and were parietal and infratentorial area in unknown cases. The results achieved with excision of these cases were good. These small vascular malformations require special ...
Background: Intracerebral hemorrhage (ICH) is the most fatal subtype of stroke. Despite limited effective therapy, there is no accepted clinical grading scale to predict in- hospital mortality, especially in developing nations. The purpose of this study was to assess the predictors of in- hospital mortality among a sample of Iranian patients with spontaneous ICH for use at the time of the first evaluation.Methods: This prospective study was carried from January 2010 to the end of January 2011. Demographic, clinical, and laboratory data of ICH patients were collected. Hematoma volume and perihematoma edema (PHE) were measured on brain computed tomography scan using ABC/2 formula. Logistic regression analysis was performed to determine independent variables contributing to in- hospital mortality.Results: Of a total 167 consecutive ICH patients, 98 patients met inclusion criteria. Mean ± standard deviation age of patients was 70.16 ± 12.52.

N2 - Acute hypertensive response is the elevation of blood pressure above normal and premorbid values that initially occurs within the first 24 hours of symptom onset in patients with intracerebral hemorrhage (ICH). We reviewed the existing data pertinent to acute hypertensive response derived from scientific guidelines, randomized trials, non-randomized controlled studies, and selected observational studies. Chronic hypertension and intracerebral hemorrhage Incidence of intracerebral hemorrhage and hypertension Spontaneous, non-traumatic ICH from intraparenchymal blood vessels makes up approximately 8-15% of all strokes. Approximately 80-85% are primary spontaneous ICH which are either secondary to arterial hypertension or cerebral amyloid angiopathy. It is estimated that 70% of the primary spontaneous ICH cases are ...

Introduction Measuring magnetic induction phase shift (MIPS) changes as a function of cerebral hemorrhage volume has the potential for being a simple method for primary and non-contact detection of the occurrence and progress of cerebral hemorrhage. Our previous MIPS study showed that the intracranial pressure (ICP) was used as a contrast index and found the primary correlation between MIPS and ICP. Materials and Methods In this study,we theoretically deduced the approximate relationship between MIPS and ICP and carried out a comparison study between MIPS and ICP on cerebral hemorrhage in rabbits in this study. Acute cerebral hemorrhage was induced by injecting autologous blood (3 to 6mL) into the brain of rabbits in the experimental group (n=7). Results The animal experiment results showed that the MIPS decreased significantly as a function of injection volume in the experimental group and the changes of ICP and MIPS of rabbits from experimental group presented a negative correlation. We also found

Computed tomography (CT) is the most common imaging method used to investigate stroke. It demonstrates haemorrhage accurately immediately after the stroke1 but as the haematoma is broken down, the characteristic hyperdensity on CT disappears, becoming indistinguishable from infarction. This has been reported to occur by 14 days for moderately sized lesions,2 and possibly sooner for smaller haemorrhages.3. Primary intracerebral haemorrhage is thought to cause more severe stroke symptoms than an infarct of the same size,4,5 and so primary intracerebral haemorrhage is considered to be a less frequent cause of mild than severe stroke. However, it is possible that this apparently low incidence is an artefact caused by the misclassification of mild stroke resulting from primary intracerebral haemorrhage as ischaemic stroke because of delay in CT scanning in epidemiological studies.6 The actual proportion of primary intracerebral haemorrhages among mild strokes is unknown. Thus there is no information ...

Background: Intracerebral hemorrhage (ICH) is an irreversible phenomenon inside the brain parenchyma resulting in mild to severe neurological deficit. Based on etiology it is broadly divided into primary and secondary. Primary ICH is usually due to the rupture of Charcot-Bouchard aneurysm and chronic hypertension. Charcot - Bouchard aneurysms are supposed to get formed due to lipohyalinosis. With the aim to evaluate the outcome of primary ICH admitted to our institute this study is performed.. Materials and methods: This is a prospective analytical study, where all the consecutive patients of the primary ICH were collected. Quantitative variables like age, the volume of hematoma, midline shift, GCS, and systolic blood pressure (SBP) were presented as mean and standard deviation (S.D). Whereas, qualitative variables like gender, site, and side of hematoma, type of treatment, best motor response were presented in frequency and percentage. The outcome of the patient was measured using the Glasgow ...
Varol and Ozaydin1 raise an important question about the effects of antihypertensive drugs and statins on arterial stiffness. In fact, antihypertensive drugs reduce large arterial stiffness, partly independently of blood pressure reduction, suggesting specific pharmacological effects on arterial remodeling.2 Furthermore, statins and other cholesterol-reducing agents have been shown to have beneficial effects on wave reflection and aortic stiffness reduction in several patient groups.3 In our study,4 25 out of 39 hypertensive patients with deep intracerebral hemorrhage (ICH) and 11 out of 15 hypertensive patients with lobar ICH received antihypertensive drugs, whereas 4 patients with deep ICH and 3 with lobar ICH received statins (Table 1). Fisher test showed no significant differences between the two groups with regard to patients treated with antihypertensive drugs (P=1, not significant) and with statins (P=0.41, not significant), confirming our hypothesis that arterial stiffness may play a key ...

OBJECTIVE: To determine whether there is an association between severe intraventricular hemorrhage and early extubation in preterm infants born before 29 weeks of gestational age and intubated at birth. METHODS: This study included 1587 preterm infants from a nationwide French population cohort (EPIPAGE-2). Secondary data on intubated preterm infants were analyzed. After gestational age and propensity score matching (1:1) we built two comparable groups: an early extubation group and a delayed extubation group. Each neonate in one group was paired with a neonate in the other group having the same propensity score and gestational age. Early extubation was defined as extubation within 48 hours of life. Severe intraventricular hemorrhages were defined as grade III or IV hemorrhages according to the Papile classification. RESULTS: After matching, there were 398 neonates in each group. Using a generalized estimating equation model, we found that intraventricular hemorrhage was not associated with early
The epinephrine (E) and norepinephrine (NE) urinary excretion before and after a mild emotional stimulus (ES) was determined in 22 patients with cerebral infarction and 30 patients with cerebral hemorrhage, as well as in 18 normotensive and 18 hypertensive controls. In patients with cerebral infarction, the majority normotensive, the emotional stimulus induced a significant increase in NE excretion, but non-significant alterations in E excretion. Similar changes were noted in normotensive controls. In patients with cerebral hemorrhage, almost all hypertensive, and in hypertensive controls, ES brought about a consistent rise in E excretion without influencing significantly the NE excretion. The presence of a constant increase in E excretion after a mild emotion not only in patients with cerebral hemorrhage but also in subjects with uncomplicated essential hypertension, suggests that the E release found in patients with cerebral hemorrhage is related to the hypertensive state pre-existing the ...

Intracerebral hemorrhage (ICH) induces potently oxidative stress responses and inflammatory processes. Isoliquiritigenin (ILG) is a flavonoid with a chalcone structure and can activate nuclear factor erythroid-2 related factor 2 (Nrf2)-mediated antioxidant system, negatively regulate nuclear factor-κB (NF-κB) and nod-like receptor family, pyrin domain-containing 3 (NLRP3) inflammasome pathways, but its role and potential molecular mechanisms in the pathology following ICH remain unclear. The present study aimed to explore the effects of ILG after ICH and underlying mechanisms. ICH model was induced by collagenase IV (0.2 U in 1 μl sterile normal saline) in male Sprague-Dawley rats weighing 280-320 g. Different doses of ILG (10, 20, or 40 mg/kg) was administrated intraperitoneally at 30 min, 12 h, 24 h, and 48 h after modeling, respectively. Rats were intracerebroventricularly administrated with control scramble small interfering RNA (siRNA) or Nrf2 siRNA at 24 h before ICH induction, and after 24 h,
Title: Cerebral Hemorrhage Produced by Thrombolytic and Anti-Thrombotic Agents: A Review. VOLUME: 2 ISSUE: 4. Author(s): Y. Suzuki, B. Q. Zhao and K. Umemura. Affiliation:Pharmacology, Hamamatsu University School of Medicine, 1-20-1 Handayama, Hamamatsu 431-3192, Japan.. Abstract: Although tissue-type plasminogen activator (t-PA) is believed to be beneficial in the treatment of acute strokes, t-PA treatment increases the risk of symptomatic cerebral hemorrhage. Therefore, the possibility of a fatal complication of cerebral hemorrhage may limit the potential benefits of anti-thrombotic and thrombolytic agents. The potential mechanisms of hemorrhage may be activated by an increase of plasmin activity that produces systemic hemostatic defects. Furthermore, plasmin activates matrix metalloproteinases (MMPs), which degrade extracellular matrix components including laminin and fibronectin. The impairment of vascular integrity and the production of hemorrhage then follow. It has been reported that MMP ...
Objective. We sought to evaluate the short- and long-term resource use and costs associated with intracerebral hemorrhage (ICH) taken from an entire population. We in addition sought to evaluate the association of oral anticoagulation (OAC) and health care costs.. Methods. This was a retrospective cohort study of adult patients (≥18 years) with ICH in the entire population of Ontario, Canada (2009-2017). We captured outcomes through linkage to health administrative databases. We used generalized linear models to identify factors associated with total cost. Analysis of OAC use was limited to patients ≥66 years of age. The primary outcome was total 1-year direct health care costs in 2020 US dollars.. Results. Among 16,248 individuals with ICH (mean age 71.2 years, male 52.3%), 1-year mortality was 46.0%, and 24.2% required mechanical ventilation. The median total 1-year cost was $26,886 (interquartile range [IQR] $9,641-$62,907) with costs for those who died in hospital of $7,268 (IQR ...
Background and purpose The pathogenesis of brain injury after intracerebral hemorrhage is thought to be due to mechanical damage followed by ischemic, cytotoxic, and inflammatory changes in the underlying and surrounding tissue. In recent years, there has been a greater research interest into the various inflammatory biomarkers and growth factors that are secreted during intracerebral hemorrhage. The biomarkers investigated in this study are tumor necrosis factor alpha (TNF alpha), C-reactive protein (CRP), homocysteine (Hcy), and vascular endothelial growth factor (VEGF). The aim of this study was to further investigate the effects of these biomarkers in predicting the acute severity outcome of intracerebral hemorrhage (ICH). Methods We conducted a retrospective chart review of patients with spontaneous ICH with TNF alpha, CRP, VEGF, and Hcy levels drawn on admission. Forty-two patients with spontaneous ICH with at least one of the above labs were included in the study. Primary outcomes
To illustrate a minimally invasive neurosurgical procedure using stereotactic catheter aspiration and clearance of supratentorial intracerebral hemorrhage (ICH), a morbid and disabling type of stroke. This cover shows a frontal trajectory placement of a Minimally Invasive Surgery plus Thrombolysis for Intracerebral Hemorrhage Evacuation (MISTIE) catheter, allowing evacuation of the ICH through a very small craniotomy.. Image guided aspiration is conducted via a rigid cannula, followed by placement of a soft drainage catheter (shown) in the epicenter of the hematoma. The catheter is secured to the scalp with several interrupted sutures. Recombinant Tissue Plasminogen Activator is administered through the catheter to dissolve the clot. The subsequent shrinking clot volume is depicted.. This study, a first to define thresholds for ICH blood volume reduction, showed an average of 70% evacuation was consistent for survival benefit with good functional outcome after 1 year. ...
Intraparenchymal hemorrhage (IPH) is one form of intracerebral bleeding in which there is bleeding within brain parenchyma. The other form is intraventricular hemorrhage (IVH). Intraparenchymal hemorrhage accounts for approx. 8-13% of all strokes and results from a wide spectrum of disorders. It is more likely to result in death or major disability than ischemic stroke or subarachnoid hemorrhage, and therefore constitutes an immediate medical emergency. Intracerebral hemorrhages and accompanying edema may disrupt or compress adjacent brain tissue, leading to neurological dysfunction. Substantial displacement of brain parenchyma may cause elevation of intracranial pressure (ICP) and potentially fatal herniation syndromes. Clinical manifestations of intraparenchymal hemorrhage are determined by the size and location of hemorrhage, but may include the following: Hypertension, fever, or cardiac arrhythmias Nuchal rigidity Subhyaloid retinal hemorrhages Altered level of consciousness Anisocoria, ...
TY - JOUR. T1 - Thermo-sensitive assembly of the biomaterial REP reduces hematoma volume following collagenase-induced intracerebral hemorrhage in rats. AU - Park, Joohyun. AU - Kim, Jong Youl. AU - Choi, Seong Kyoon. AU - Kim, Jae Young. AU - Kim, Jae Hwan. AU - Jeon, Won Bae. AU - Lee, Jong Eun. PY - 2017/8. Y1 - 2017/8. N2 - Intracerebral hemorrhage (ICH) frequently results in severe disabilities and high mortality. RGD-containing elastin-like polypeptide (REP), a modified elastin-like polypeptide (ELP), is a thermally responsive biopolymer. REP has high affinity for cells and is known to show non-immunotoxicity, -cytotoxicity, and -inflammatory responses. Here we found that administration of REP in the acute phase of the ICH rat model reduced the hematoma volume, decreased the number of activated microglia, attenuated the expression of von Willebrand Factor (vWF), and prevented the leakage of immunoglobulin G (IgG) into the cerebral parenchyma without any occlusion of intact microvessels. ...
A 4-year-old previously healthy boy presented with a non-traumatic right parietal hemorrhage. A second life-threatening left cerebral hemorrhage occurred three weeks later and was decompressed with a craniotomy. Transthoracic echocardiography revealed a hypermobile elongated tumor of the mitral valve. The cardiac tumor was successfully resected three weeks after the craniotomy. Histological examination of the cardiac tumor revealed a papillary lesion of spindle cells with smooth muscle cell differentiation. In view of the histological findings and the clinical symptoms, a cellular myofibroblastic tumor was considered the most likely diagnosis in our patient. Although a cardiac tumor is a rare cause of a cerebral hemorrhage, a cardiac evaluation is recommended in pediatric patients with a cerebral hemorrhage of unknown etiology ...
Authors: Beslow LA, Abend NS, Gindville MC, Bastian RA, Licht DJ, Smith SE, Hillis AE, Ichord RN, Jordan LC.. IMPORTANCE Seizures are believed to be common presenting symptoms in neonates and children with spontaneous intracerebral hemorrhage (ICH). However, few data are available on the epidemiology of acute symptomatic seizures or the risk for later epilepsy. OBJECTIVE To define the incidence of and explore risk factors for seizures and epilepsy in children with spontaneous ICH. Our a priori hypotheses were that younger age at presentation, cortical involvement of ICH, acute symptomatic seizures after presentation, ICH due to vascular malformation, and elevated intracranial pressure requiring urgent intervention would predict remote symptomatic seizures and epilepsy. DESIGN Prospective cohort study conducted between March 1, 2007, and January 1, 2012. SETTING Three tertiary care pediatric hospitals. PARTICIPANTS Seventy-three pediatric subjects with spontaneous ICH including 20 perinatal ...

A number of studies have cited immune cell infiltration as a mechanism for secondary injury following intracerebral hemorrhage. However, the role of monocytes remains poorly understood. We hypothesized that monocytes are a beneficial cell type that help remove extravasated blood and other pathogenic substances that enter brain parenchymal tissue during a hemorrhagic stroke. Using macrophage Fas-induced apoptosis (MAFIA) mice, this study documents a time course of monocyte infiltration into brain tissue. We then systemically knocked down monocytes prior to initiating an intracerebral hemorrhage, and studied the motor and cognitive outcomes relative to a vehicle treated group. The genetic alteration present in MAFIA mice causes the co-expression of green fluorescent protein and a suicide protein, exclusively in monocytes and dendritic cells. We established a time course of monocyte infiltration by counting cells expressing green fluorescent protein in brain parenchymal tissue at four time points ...
The use of Minimally Invasive Parafascicular Surgery (MIPS) techniques for removal of traumatic hematoma is encouraging, innovative and promising. Those are the insights from Julian Bailes, MD, Chair of the Joint Section on Neurotrauma and Critical Care for the American Association of Neurological Surgeons (AANS) and Congress of Neurological Surgeons (CNS), following the evidence highlighted in two abstracts on the subject at the recent AANS Annual Scientific Meeting.. Results from the 10-patient multi-center study, led by Jefferson Chen, MD, PhD, from the University of California Irvine, concluded that techniques using Minimally Invasive Parafascicular Surgery (MIPS) may be used effectively and safely to remove deep subcortical hemorrhages and may improve the patients hospital course and ultimate neurological outcome. Technologies used in the MIPS approach include the NICO BrainPathâ for subcortical access and Myriadâ for hemorrhage evacuation.. This is the first multi-center experience ...
Background: Antiplatelet treatment remains the first choice for primary and secondary prevention of vascular diseases; even so, expected benefits may be offset by risk of bleeding, particularly cerebral hemorrhage. The aim of this study was to assess the influence of antiplatelet treatment on clinical outcome at hospital discharge. Materials and Methods: Consecutive patients with first-ever stroke due to a primary intraparenchymal hemorrhage were prospectively identified over a 4-year period (2000â€2003). Data on hemorrhage location, vascular risk factors, and antiplatelet and anticoagulant treatment were collected. At discharge, outcome was measured using the modified Rankin Scale (disabling stroke ≥3). Patients treated with anticoagulant therapy were excluded from the study. Results: Of 457 consecutive patients with cerebral hemorrhage, 94 (20.5%) had been taking antiplatelet agents. The treated patients (mean age for antiplatelet group 78.9 ± 9.0 years) were older than the ...
The germinal matrix is the site of proliferating neuronal and glial precursors in the developing brain, which is located above the caudate nucleus, in the floor of the lateral ventricle, and caudothalamic groove. The germinal matrix contains a rich network of fragile thin-walled blood vessels. Hence the microcirculation in this particular area is extremely sensitive to hypoxia and changes in perfusion pressure. It is most frequent before 35 weeks gestation and is typically seen in very low birth-weight (,1500g) premature infants, because they lack the ability for auto regulation of cerebral blood flow. Consequently, increased arterial blood pressure in these blood vessels leads to rupture and hemorrhage into germinal matrix.[2]. ...
Background There is much uncertainty about the effects of early lowering of elevated blood pressure (BP) after acute intracerebral haemorrhage (ICH). Our aim was to assess the safety and efficiency of this treatment, as a run-in phase to a larger trial.. Methods Patients who had acute spontaneous ICH diagnosed by CT within 6 h of onset, elevated systolic BP (150-220 mm Hg), and no definite indication or contraindication to treatment were randomly assigned to early intensive lowering of BP (target systolic BP 140 mm Hg; n=203) or standard guideline-based management of BP (target systolic BP 180 mm Hg; n=201). The primary efficacy endpoint was proportional change in haematoma volume at 24 h; secondary efficacy outcomes included other measurements of haematoma volume. Safety and clinical outcomes were assessed for up to 90 days. Analysis was by intention to treat. This trial is registered with, number NCT00226096.. Findings Baseline characteristics of patients were similar ...

Therefore, the impact of BP changes and course on HG and clinical outcome in patients with acute ICH was determined. Methods: In total, 117 consecutive patients with acute (,6 h) supratentorial ICH underwent baseline and 24-h CT scans, CT angiography for the detection of the spot sign and non-invasive BP monitoring at 15-min intervals over the first 24 h. Maximum and minimum BP, maximum BP ...
Seventy cases of intracerebral hematomas were analysed, forty-six of spontaneous origin and remainder of traumatic one, which had been experienced in Seoul National University Hospital between March, 1970 and June, 1975. The results were as follows: A. Among forth-six cases of spontaneous intracerebral hematomas, twenty-six cases(52%) were primary intracerebral hematomas, normotensive or hypertensive, seven aneurismal ruptures(15%), seven arteriovenous malformations(15%), two cerebral rete mirabilies, one tumor bleeding, one leukemia, one idiopathic thrombocytopenic and one due to other blood dyscrasia. 1. Among twenty-six cases of primary intracerebral hematomas, angiography was performed in all and fourteen cases were operated. The sites of hemorrhage were as follows: a. Putaminal hemorrhage:17 cases(65%)(two cases associated with intraventricular hematoma). b. Thalamic hemorrhage:5 cases(19%)(two cases associated with intraventricular hematoma). c. Subcortical hemorrhage:4 cases(16%). 2. ...
BACKGROUND:Angiopoietin-like 4 (ANGPTL4) is neuroprotective when administered acutely for the treatment of cerebral ischemia. The aim of the present study was to evaluate the preventive effects of ANGPTL4 on the formation of brain edema and to determine whether it promotes the recovery of neurological function following intracerebral hemorrhage (ICH). MATERIAL AND METHODS:Recombinant human ANGPTL4 (rhANGPTL4; 40 µg/kg) or a vehicle was administered intraperitoneally 5 min prior to bacterial collagenase-induced ICH in male C57/B6J mice. Behavioral tests were performed prior to ICH and at days 1, 3, 7, 14, 21, and 28 after ICH. Brain edema and hematoma volume were examined separately using the wet weight/dry weight method and hematoxylin-eosin staining. The integrity of the tight and adherens junctions was quantified via immunofluorescence. The ultrastructure of the blood-brain barrier (BBB) was examined using transmission electron microscopy.

TY - JOUR. T1 - Early elective surgical exploration of spontaneous intracerebral hematomas of unknown origin. T2 - Clinical article. AU - Elhammady, Mohamed. AU - Baskaya, Mustafa K.. AU - Heros, Roberto. PY - 2008/12/1. Y1 - 2008/12/1. N2 - Object. The management of non-life threatening spontaneous intraparenchymal hemorrhage with no obvious medical etiology in patients and the lack of findings on images has not been clearly defined. In general, the current practice is to treat these patients conservatively and repeat studies to rule out a treatable cause 6 weeks to 3 months later; more often than not these repeated studies fail to reveal any findings, and the patient is treated conservatively. For years, the senior author (R.C.H.) has treated these patients with early surgical exploration. This study was undertaken prospectively to ascertain the frequency of positive findings during surgical exploration. Methods. Between 2000 and 2007, the authors prospectively collected data from 9 cases (4 ...
The study population comprised 288 consecutive patients with aSAH. The mean total hemorrhage volume was 74.9 ml. Thirty-eight patients (13.2%) developed seizures. The mean hemorrhage volume in patients who developed seizures was significantly higher than that in patients with no seizures (mean difference 17.3 ml, p = 0.01). In multivariate analysis, larger hemorrhage volume on initial CT scan and hemorrhage volume , 50 ml (OR 2.81, p = 0.047, 95% CI 1.03-7.80) were predictive of seizures. Forty-eight patients (17%) developed shunt-dependent hydrocephalus. The mean hemorrhage volume in patients who developed shunt-dependent hydrocephalus was significantly higher than that in patients who did not (mean difference 17.2 ml, p = 0.006). Larger hemorrhage volume and hemorrhage volume , 50 ml (OR 2.45, p = 0.03, 95% CI 1.08-5.54) were predictive of shunt-dependent hydrocephalus. Hemorrhage volume had adequate discrimination for the development of seizures (AUC 0.635) and shunted hydrocephalus (AUC ...
The main pathophysiological factors of ICH include hematoma size and edema [38]. The formation of edema, which is mainly caused by disruption of the BBB following ICH, is associated with patient outcome. The BBB is composed of endothelial cells, tight junction proteins, astrocyte end-feet, and pericytes, which have the function of maintaining homeostasis of the neuro-parenchymal microenvironment [6]. Loss of BBB integrity is an important pathophysiological change that contributes to initiation of the inflammatory cascade, edema formation, and ultimately poor outcome [39]. In this study, the effect of MSCs on BBB leakage in ICH rats and relevant mechanisms were investigated after intravenous transplantation of MSCs.. Besides endothelial cell activation, vascular ONOO−, which is formed by NO and superoxide anion, is closely related to BBB leakage [37]. Studies have already shown that ONOO− alone is sufficient to induce BBB leakage, endothelial dysfunction, and neurodegeneration [40,41]. ...

Abstract BACKGROUND: Identification of lobar spontaneous intracerebral haemorrhage associated with cerebral amyloid angiopathy (CAA) is important because it is associated…
Cerebral amyloid angiopathy (CAA) has been associated with atypical dementia and a variety of other neurological disorders. Intracerebral hemorrhage is the most striking manifestation of CAA. A 63-year-old patient is described who sustained four intracerebral hemorrhages although he had no predisposing factors other than CAA. The neurological and pathological features of CAA are reviewed, with particular emphasis on the problem of CAA-associated intracerebral hemorrhage. On the basis of the experience with this case, it is recommended that adjacent brain parenchyma be biopsied in all patients undergoing evacuation of intracerebral hematomas of unclear etiology. ...
Post-admission hematoma expansion in patients with intracerebral hemorrhage (ICH) comprises a simultaneous major clinical problem and a possible target for medical intervention. In any case, the ability to predict and observe hematoma expansion is of great clinical importance. We review radiological concepts in predicting and observing post-admission hematoma expansion. Hematoma expansion can be observed within the first 24 h after symptom onset, but predominantly occurs in the early hours. Thus capturing markers of on-going bleeding on imaging techniques could predict hematoma expansion. The spot sign observed on computed tomography angiography is believed to represent on-going bleeding and is to date the most well investigated and reliable radiological predictor of hematoma expansion as well as functional outcome and mortality. On non-contrast CT, the presence of foci of hypoattenuation within the hematoma along with the hematoma-size is reported to be predictive of hematoma expansion and ...

PY - 2002/5/14. Y1 - 2002/5/14. N2 - Background: Supratentorial intracerebral hematomas often are evacuated in rapidly deteriorating patients. Surgery may prevent death but not necessarily disability. The authors studied the outcome of emergent clot evacuation in patients with worsening massive intracerebral hemorrhage. Methods: The authors reviewed data on 26 consecutive, acutely worsening patients with nontraumatic intracerebral hemorrhage who had surgery for clot evacuation. All patients had clinical (stupor or coma, loss of pontomesencephalic brainstem reflexes, extensor posturing) or radiologic (midline shift of septum pellucidum ≥1 cm downward or obliteration of the ambient and suprasellar cisterns caused by displacement of the temporal uncus) signs of herniation. Outcome was defined using ...
Intracerebral hemorrhage (ICH) often produces severe neurological deficits in survivors, which is closely related with secondary corticospinal tract (CST) injury. Rodent models of ICH have greatly promoted the understanding of histopathology underlying brain injury and were employed widely for exploring therapeutic strategies. This study investigated WD in pyramidal tract, as part of CST, after experimental ICH using diffusion tensor imaging (DTI) and T2-weighted imaging as well as with histological correlations. The results demonstrated DTI as a valuable tool for detecting WD in early phase and for longitudinal monitoring of its progress at different stages with more accuracy than T2-weighted imaging ...

We searched our electronic database for all patients aged 18 years or above who developed first ICH in the presence of anticoagulation with warfarin for non-valvular AF (ICH-W group) from the three hospitals, and matched them with a comparison group (ICH-C group) without taking warfarin at a 1:1 ratio for age (±1 year), gender, and admission year. The comparison group comprised patients from the medical unit of PMH (principal study centre) who had a first episode of ICH without anticoagulation, regardless of any AF. Patients with isolated subdural, subarachnoid, or intraventricular haemorrhage were excluded. We retrieved and compared the data regarding neurological impairment and investigation findings, estimated the ICH volume on CT through the ABC/2 method, and calculated the ICH score.3 4 Hospital mortality and 6-month modified Rankin Scale score (mRS, 0-6) were selected as primary and secondary outcomes, respectively. We used independent sample t test and Mann-Whitney U test for univariate ...
Authors: Beslow LA, Abend NS, Gindville MC, Bastian RA, Licht DJ, Smith SE, Hillis AE, Ichord RN, Jordan LC.. IMPORTANCE Seizures are believed to be common presenting symptoms in neonates and children with spontaneous intracerebral hemorrhage (ICH). However, few data are available on the epidemiology of acute symptomatic seizures or the risk for later epilepsy. OBJECTIVE To define the incidence of and explore risk factors for seizures and epilepsy in children with spontaneous ICH. Our a priori hypotheses were that younger age at presentation, cortical involvement of ICH, acute symptomatic seizures after presentation, ICH due to vascular malformation, and elevated intracranial pressure requiring urgent intervention would predict remote symptomatic seizures and epilepsy. DESIGN Prospective cohort study conducted between March 1, 2007, and January 1, 2012. SETTING Three tertiary care pediatric hospitals. PARTICIPANTS Seventy-three pediatric subjects with spontaneous ICH including 20 perinatal ...

Keywords:Cerebral hemorrhage, death, recurrent stroke, myocardial infarction, outcome, south carolina, Caucasian, ICH, myocardial, Intracerebral hemorrhage, stroke belt, CAs, MI, hypertension, hyperlipidemia, racial disparity. Abstract: The aim of this study was to assess short- and long-term outcomes of patients hospitalized with intracerebral hemorrhage (ICH) in South Carolina. Patients with a primary diagnosis of ICH (ICD-9-CM code 431) discharged during 2002 were identified in the South Carolina hospital discharge database. Kaplan-Meier estimates of recurrent stroke, myocardial infarct, vascular death, all-cause death, and composite events were calculated at 1 month, 6 months, and 1, 2, 3, and 4 years. Age- and ...
We examined the potential role of the extra-cellular matrix-degrading enzyme, matrix metalloproteinase-9 (MMP-9), in the pathogenesis of cerebral amyloid angiopathy (CAA)-induced spontaneous hemorrhage. The amyloid-beta peptide (Abeta) induced the synthesis, release and activation of MMP-9 in murine cerebral endothelial cells, resulting in increased extracellular matrix degradation. Furthermore, extensive MMP-9 immunoreactivity was observed in CAA-vessels with evidence of microhemorrhage in aged APPsw transgenic mice, but not detected in aged wild type or young APPsw mice. These results suggest that increased vascular MMP-9 expression, stimulated by Abeta, may play a role in the pathogenesis of spontaneous intracerebral hemorrhage in patients with CAA.. ...

OBJECTIVE: Early hematoma expansion is a known cause of morbidity and mortality in patients with intracerebral hemorrhage (ICH). The goal of this study was to identify clinical predictors of ICH growth in the acute stage.. MATERIALS AND METHODS: We studied 201 patients with acute (,6h) deep ganglionic ICH. Patients underwent CT scan at baseline and hematoma expansion (,33% or ,12.5ml increase) was determined on the second scan performed within 24h. Fourteen clinical and neuroimaging variables (age, gender, GCS at admission, hypertension, diabetes mellitus, kidney disease, stroke, hemorrhagic, antiplatelet use, anticoagulant use, hematoma density heterogeneity, hematoma shape irregularity, hematoma volume and presence of IVH) were registered. Additionally, blood pressure was registered at initial systolic BP (i-SBP) and systolic BP 1.5h after admission (1.5h-SBP). The discriminant value of the hematoma volume and 1.5h-SBP for hematoma expansion were determined by the receiver operating ...

Brain vascular malformations, including arteriovenous malformations (AVM), cavernous malformations (CVM) and aneurysms, are a source of life-threatening risk of intracranial hemorrhage. The etiology and pathogenesis are unknown. There is no medical therapy presently available. Prevention of spontaneous intracerebral hemorrhage (ICH) is the primary reason to treat brain vascular malformations. The goal of this study is to: begin pilot studies to lay the groundwork for future clinical trials to develop medical therapy to decrease ICH risk.. Matrix metalloproteinases (MMPs) regulate the extracellular matrix in association with various hemorrhagic brain disorders. MMP-9 has been most consistently associated with vascular wall instability and hemorrhagic brain disorders. Doxycycline, a non-specific MMP inhibitor, may enhance vascular stability, thus reducing the risk of spontaneous hemorrhage in brain vascular malformations by decreasing MMP-9 activity. ...

AU - Kim, Byung Moon. PY - 2009. Y1 - 2009. N2 - Objective: It has been suggested that elevated cardiac troponin T (cTnT) level is a marker of increased risk of mortality in acute ischemic stroke and subarachnoid hemorrhage (SAH). However, the association of serum cTnT level and prognosis of intracerebral hemorrhage (ICH) has been sparsely investigated. The aim of this study was to identify the relationship between cTnT level and the outcome in patients with spontaneous ICH. Methods: We retrospectively investigated 253 patients identified by a database search from records of patients admitted in our department for ICH between January 1, 2003 and December 31, 2007. The patients were divided into 2 groups; the patients in group 1 (n=225) with serum cTnT values of 0.01 ng/mL or less, and those in group 2 ...
BACKGROUND: Tranexamic acid reduces death due to bleeding after trauma and postpartum haemorrhage. OBJECTIVE: The aim of the study was to assess if tranexamic acid is safe, reduces haematoma expansion and improves outcomes in adults with spontaneous intracerebral haemorrhage (ICH).

N2 - Intracerebral hemorrhage (ICH) is a common and serious type of stroke. Recent studies have shown that inherited factors that affect the development of the vessel wall can increase the risk of ICH. We studied endoglin as a candidate gene in patients with sporadic ICH, since mutations in this gene can cause telangiectasia formation. One hundred three patients with sporadic ICH and 202 controls were studied. The polymerase chain reaction and single- strand conformational polymorphism analysis were used to screen for mutations in exon 7 of the endoglin gene. No coding mutations in exon 7 were identified in the ICH patients or controls. A 6-base intronic insertion was found 26 ...
Expert data generally recommends permissive hypertension (220/120mm Hg) if not treated with thrombolytics for the first 24 hours. Acute hemorrhagic stroke presents a particularly difficult situation. Blood pressures tend to run high in these patients and this has been found to be an independent predictor of poor prognosis. The Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT) enrolled 404 patients after acute intracerebral hemorrhage to either an intensive blood pressure lowering arm (≤140mmHg in one hour maintained for seven days) or guideline based therapy (goal systolic of 180mmHg). The first phase of this study published in 2008 found intensive lowering of blood pressure was feasible and associated with a decreased relative risk of hematoma growth. The primary outcome in the final analysis (INTERACT2) was death or major disability using the modified Rankin score (mRS). There was a significantly lower mRS in patients undergoing intensive therapy with no ...

AU - Holtzman, David M.. AU - Hsu, Chung Y.. AU - Xu, Jian. PY - 2005/3/15. Y1 - 2005/3/15. N2 - Spontaneous intracerebral hemorrhage (ICH) is one of the most recognized complications of cerebral amyloid angiopathy (CAA), but little is known about the molecular pathogenesis of this life-threatening complication. In this review, we present preliminary evidence which suggests that the extracellular-matrix-degrading protease, matrix metalloproteinase-9 (MMP-9), may play a role in the development of spontaneous ICH resulting from CAA. The amyloid-beta peptide (Aβ) induced the synthesis, cellular release, and activation of MMP-9 in murine cerebral endothelial cells (CECs), resulting in increased extracellular matrix (ECM) degradation. Furthermore, in a mouse model of CAA (APPsw transgenic mice), MMP-9 ...

N2 - RNA expression profiles in rat brain were examined 24 h after ischemic stroke, intracerebral haemorrhage, kainate-induced seizures, insulin-induced hypoglycemia, and hypoxia and compared to sham- or untouched controls. Rat oligonucleotide microarrays were used to compare expression of over 8000 transcripts from three subjects in each group (n = 27). Of the somewhat less than 4000 transcripts called present in normal or treated cortex, 5-10% of these were up-regulated 24 h after ischemia (415), haemorrhage (205), kainate (187), and hypoglycemia (302) with relatively few genes induced by 6 h of moderate (8% oxygen) hypoxia (15). Of the genes induced 24 h after ischemia, haemorrhage, and hypoglycemia, approximately half were unique ...
OBJECTIVE: To perform a systematic review and pooled meta-analysis of published studies to assess whether the presence of leukoaraiosis on neuroimaging before treatment with thrombolysis (IV or intra-arterial) is associated with an increased risk of symptomatic intracerebral hemorrhage (sICH) or poor functional outcome. METHODS: We included studies of patients with acute ischemic stroke, treated with IV or intra-arterial thrombolysis, which assessed functional outcome (3-month modified Rankin Scale [mRS]) or sICH in relation to leukoaraiosis on pretreatment neuroimaging (CT or MRI). We used random-effects models to calculate pooled relative risks (RR) of sICH and poor functional outcome (mRS ≥ 2) for any vs no leukoaraiosis (using any rating scale) and for no to mild vs moderate to severe leukoaraiosis (using the Van Swieten or Fazekas Schmidt scale). RESULTS: We identified 15 studies (total n = 6,967). For sICH outcome, the RR was 1.65 (n = 5,551; 95% confidence interval [CI] 1.26-2.16, p = 0.001)
NLRP6 inflammasome, one of the important intracellular innate immune sensors, has been shown to regulate immune responses. However, its roles in the intracerebral hemorrhage (ICH) are completely not clear. In the present study, we investigated the expression profile and biological roles of NLRP6 inflammasome in perihematomal brain tissues of mice subjected to ICH. In this study, we investigated the expression profile of NLRP6 inflammasome in the perihematomal brain tissues and explored the biological role of NLRP6 inflammasome upon acute brain injury in mice subjected to ICH. Increased expression of NLRP6 inflammasome was found in perihematomal brain tissues ranging from 6 h to 3 days, with a peak level at 1 day after ICH. Immunohistochemistry staining also showed that NLRP6 inflammasome was significantly increased in the perihematomal brain tissues at 1 day after ICH. Moreover, immunofluorescence staining showed that NLRP6 inflammasome was mainly colocalized in glial fibrillary acidic protein ...

N2 - The value of surgery for patients with intracerebral hemorrhage (ICH) remains a topic of debate. Although several studies have been unable to prove the benefit of surgical intervention of ICH, there is available evidence to suggest that some patients may experience favorable outcome with surgery. Identifying optimal candidates and the timing of surgery for the treatment of ICH are crucial issues. Studies have explored the value of early and ultra-early surgical intervention, as well as the role of stereotactic hematoma evacuation.

The artificial heart valve can cause some emboli and high blood pressure. Furthermore, she was in blood thinner that can make this hemorrhage worse. The brain hemorrhage occurred in the dominant side of the brain, the left side in the back where people understand, talk and read. She had difficulty in reading, writing, understanding and getting sleepy. She could not be off blood thinner for long. The brain hemorrhage can also be related to tumor. She was urgently taken to surgery; the hematoma was evacuated through the craniotomy and was sent for pathology. The bleeding was controlled and the patient went to intensive care unit and CT scan showed no more hemorrhage. Pathology showed no tumors. She required extensive speech therapy for one year to learn how to talk. Furthermore, when therapist and doctors told her ...
