RESUMO
Background: Stroke is the third leading cause of death in Malaysia. This study aims to evaluate the mortality risk factors of spontaneous intracerebral haemorrhage (ICH) in Hospital Kuala Lumpur, Malaysia. Methods: A single centre prospective cohort study was performed between 1 May 2017 and 30 April 2018 for patients above 18 years old with spontaneous ICH. Patients exhibiting haemorrhage due to tumours and ruptured arteriovenous malformations were excluded. The demographics, clinical parameters, radiology findings, surgical intervention, mortality at 30 days and outcome based on modified Rankin score (MRS) grading were recorded. Selected variables were incorporated into a binary logistic regression to determine the outcome predictors of mortality. Results: A total of 292 patients were recruited into the study. The findings showed that the mean age of ICH patients was 48.9 years old. Most of the lesions were located in the putamen (45.9%). More than half (61.0%) of the patients presented with a good outcome whereas 39.0% of the patients presented with a poor outcome. The mortality rate at 30 days was 29.1%. The important predictors for mortality were male (odds ratio [OR] = 0.343; P = 0.043), concomitant use of warfarin and aspirin (OR = 14.696; P = 0.007), ischaemic heart disease [IHD] (OR = 0.007; P = 0.003), brainstem bleed (OR = 0.001; P = 0.001), the presence of intraventricular haemorrhage [IVH] (OR = 0.198; P = 0.049) and surgery. Conclusion: Most diagnosed ICH patients in Malaysia were at a younger age (mean of 48.9 years old) with the significant mortality predictors were IVH, IHD, surgery and brainstem bleed.
RESUMO
OBJECTIVE: Oxidation contributes to secondary brain injury after spontaneous intracerebral haemorrhage (SIH). One study found lower levels of total antioxidant capacity (TAC) in the blood in patients with SIH than in healthy subjects. However, there are no data on blood TAC levels and survival in patients with SIH. Therefore, the objective of our study was to determine if an association exists between serum TAC levels and mortality in patients with SIH. METHODS: We included patients with severe supratentorial SIH. We considered severe when Glasgow Coma Scale (GCS) < 9. Patients from 6 Spanish hospitals were included in this observational and prospective study. Serum TAC levels at days 1, 4 and 8 of SIH were determined. Thirty-day mortality was our end-point study. RESULTS: Non-surviving patients compared with surviving patients showed higher serum TAC levels at day 1 (p < 0.001), 4 (p < 0.001) and 8 (p = 0.001). An area under the curve was found for the prediction of 30-day mortality by serum TAC levels of 0.92 (95% CI = 0.85-96%; p < 0.001). Multiple logistic regression analysis showed an association of serum TAC levels with 30-day mortality (odds ratio = 16.513; 95% CI = 2.548-107.015; p = 0.003) controlling for midline shift, glycemia, early evacuation of SIH, intracerebral haemorrhage (ICH) score, age and volume of SIH. CONCLUSIONS: The new findings of this study are that serum TAC levels are higher in non-surviving than in surviving patients, and that they are associated with mortality and could be used to predict mortality.

BACKGROUND: Although acute kidney injury (AKI) is a known risk factor for adverse clinical outcomes in patients with spontaneous intracerebral haemorrhage (SICH), little is known about the predisposing factors that contribute to renal failure and short-term prognosis in the setting of SICH already complicated by AKI. In this study, we aimed to identify the renal failure factors in SICH patents with AKI. METHODS: Five hundred forty-three patients with SICH complicated by differential severities of AKI who were admitted to the First Affiliated Hospital of Fujian Medical University from January 2016 to December 2018 were retrospectively studied. Logistic regression and receiver operator characteristic (ROC) curve analysis were performed to determine the best predictive and discriminative variables. Multivariate Cox regression analysis was performed to identify prognostic factors for renal recovery. RESULTS: In the multivariable adjusted model, we found that hypernatremia, metabolic acidosis, elevated serum creatine kinase, hyperuricaemia, proteinuria, and the use of colloids and diuretics were all independent risk factors for the occurrence of stage 3 AKI in SICH patients. The area under the curve analysis indicated that hypernatremia and hyperuricaemia were predictive factors for stage 3 AKI, and the combination of these two parameters increased their predictability for stage 3 AKI. Kaplan-Meier survival curves revealed that the renal recovery rate in SICH patients with stages 1 and 2 AKI was significantly higher than that in SICH patients with stage 3 AKI. Multivariate Cox regression analysis suggested that hypernatremia and the occurrence of stage 3 AKI are predictors for poor short-term renal recovery. CONCLUSIONS: These findings illustrate that hypernatremia and hyperuricaemia represent potential risk factors for the occurrence of stage 3 AKI in SICH patients. Those patients with hypernatremia and stage 3 AKI were associated with a poor short-term prognosis in renal recovery.

AIM AND CLINICAL RATIONALE FOR THE STUDY: Spontaneous intracerebral haemorrhage (sICH) is an acute life-threatening injury and constitutes 10-15% of first-ever stroke cases. The Surgical Trials in Intracerebral Haematoma studies (STICH and STICH II) represent the two foremost studies in the field, however, with arguable shortcomings. To find more accurate criteria, we aimed to correlate the preoperative neurological and neuroimaging findings with the clinical outcome of operated patients. MATERIALS AND METHODS: In this retrospective study, sICH patients were recruited from the Central Denmark Region from 2010 to 2016. We evaluated the patients' medical records regarding preoperative Glasgow Coma Scale (GCS) 6 months and one year after surgery, focal neurological defects, thrombolytic treatment, pupil status, and haemorrhage localization visualized by neuroimaging. The patients' clinical outcome was assessed using the Glasgow Outcome Scale (GOS). RESULTS: Based on logistic multiple linear analysis, age, basal ganglia haemorrhage and mass effect had significant effect on the mortality rate. Besides, age, basal ganglia haemorrhage, intra ventricular haemorrhage and pupil difference had significant correlation with good outcome (GOS>3). CONCLUSIONS AND CLINICAL IMPLICATIONS: Neurosurgical treatment of the sICH patients is indicated only if age and potentially improved morbidity is carefully evaluated considering the STICH and this study; otherwise, we will just increase the health care burden with a number of extremely care-dependent patients.

BACKGROUND: Haematoma expansion due to raised blood pressure in spontaneous intracerebral haemorrhage may determine outcome. The aim of this study was to determine safety and efficacy of lowering blood pressure in acute spontaneous intracerebral haemorrhage. METHODS: This open label, multicentric trial randomized patients ≥18 years with spontaneous intracerebral haemorrhage with no secondary cause within 72 h of onset to tight BP control arm where treatment was initiated if mean arterial pressure (MAP) was ≥115 mm of Hg and conventional BP control arm where treatment was initiated if MAP was ≥130 mm of Hg. The MAP was maintained in the respective arm for another 72 h after which both arms had MAP below 115 mm of Hg. Primary outcome was modified Rankin Scale at 90 days. RESULTS: 118 patients, 59 in each arm were included. Follow up was available for all. Baseline characteristics were similar. At 90 days there was no significant difference between median mRS between the two arms. Odds Ratio for "poor outcome" (mRS 3-6) in the tight control arm (safety of the intervention) against "good outcome" (mRS 0-2) was not significant (OR 0.70 [95% CI 0.34-1.47] p = 0.35). Efficacy of the intervention in the form of Odds Ratio for "good outcome" in the tight control arm was not significant (OR 1.43 [95% CI 0.68-2.99], p = 0.35). CONCLUSION: In patients with spontaneous intracerebral haemorrhage who present within 72 h of the onset of symptoms, MAP can be safely lowered if it crosses 115 mm of Hg but it does not improve clinical outcome.
RESUMO
BACKGROUND AND AIMS: Stroke is often accompanied by hyperglycaemia, and this has an important impact on prognosis. The aim of this study was to investigate the relationship between early hyperglycaemia and the outcome of spontaneous intracerebral haemorrhage (sICH). METHODS: A systematic literature search on PubMed, Embase, Cochran, WANFANG DATA, VIP and CNKI databases was conducted, and eight eligible studies were retrieved. Relative risks and 95% confidence interval (CI) in the hyperglycaemia group compared with the non-hyperglycaemia group were calculated and meta-analysed when possible. RESULTS: Eight controlled trials and cohort studies totalling 3756 patients addressing early hyperglycaemia and the outcome of sICH were compiled for this meta-analysis. Cut-off points for defining hyperglycaemia was 6.1-8.3 mmol/L, and the median cut-off value was 7.5 mmol/L. Studies were assigned to one of the two subgroups: the group A (for studies with the values of glucose concentrations above the median cut-off) and the group B (for studies with the values of glucose concentrations below the median cut-off). The RR for short-term death associated with hyperglycaemia was 3.65 (95% confidence interval (CI) (3.08, 4.33); P < 0.0001). In the subgroup analysis, the relative risk values were 3.46 (95% CI (1.66, 7.20); P = 0.0009) and 3.53 (95% CI (2.92, 4.26); P < 0.00001) for the groups A and B respectively. The publication bias showed that Egger's test (P > 0.1), Begg's test (P > 0.05) and Nfs0.05 exceeded included studies. CONCLUSIONS: Early hyperglycaemia can significantly increase the rate of early-term death in patients with sICH, independent of the cut-off points for hyperglycaemia.

Background: Acute spontaneous intracerebral haemorrhage is a devastating form of stroke. Prognostication after ICH may be influenced by clinicians' subjective opinions. Purpose: To evaluate subjective predictions of 6-month outcome by clinicians' for ICH patients in a neurocritical care using the modified Rankin Scale (mRS) and compare these to actual 6-month outcome. Method: We included clinicians' predictions of 6-month outcome in the first 48 h for 52 adults with ICH and compared to actual 6-month outcome using descriptive statistics and multilevel binomial logistic regression. Results: 35/52 patients (66%) had a poor 6-month outcome (mRS 4-6); 19/52 (36%) had died. 324 predictions were included. For good (mRS 0-3) versus poor (mRS 4-6), outcome, accuracy of predictions was 68% and exact agreement 29%. mRS 6 and mRS 4 received the most correct predictions. Comparing job roles, predictions of death were underestimated, by doctors (12%) and nurses (13%) compared with actual mortality (36%). Predictions of vital status showed no significant difference between doctors and nurses: OR = 1.24 {CI; 0.50-3.05}; (p = 0.64) or good versus poor outcome: OR = 1.65 {CI; 0.98-2.79}; (p = 0.06). When predicted and actual 6-month outcome were compared, job role did not significantly relate to correct predictions of good versus poor outcome: OR = 1.13 {CI;0.67-1.90}; (p = 0.65) or for vital status: OR = 1.11 {CI; 0.47-2.61}; p = 0.81). Conclusions: Early prognostication is challenging. Doctors and nurses were most likely to correctly predict poor outcome but tended to err on the side of optimism for mortality, suggesting an absence of clinical nihilism in relation to ICH.
RESUMO
Background and purpose: The role of surgery in the treatment of intracerebral haemorrhage (ICH) remains controversial. Whereas open surgery has failed to show any clinical benefit, recent studies have suggested that minimal invasive procedures can indeed be beneficial, especially when they are applied at an early time point. This retrospective study therefore evaluated the feasibility of a free-hand bedside catheter technique with subsequent local lysis for early haematoma evacuation in patients with spontaneous supratentorial ICH. Methods: Patients with spontaneous supratentorial haemorrhage of a volume of >30 mL who were treated with bedside catheter haematoma evacuation were identified from our institutional database. The entry point and evacuation trajectory of the catheter were based on a 3D-reconstructed CT scan. The catheter was inserted bedside into the core of the haematoma, and urokinase (5,000 IE) was administered every 6 h for a maximum of 4 days. Evolution of haematoma volume, perihaemorrhagic edema, midline-shift, adverse events and functional outcome were analyzed. Results: A total of 110 patients with a median initial haematoma volume of 60.6 mL were analyzed. Haematoma volume decreased to 46.1 mL immediately after catheter placement and initial aspiration (with a median time to treatment of 9 h after ictus), and to 21.0 mL at the end of urokinase treatment. Perihaemorrhagic edema decreased significantly from 45.0 mL to 38.9 mL and midline-shift from 6.0 mm to 2.0 mm. The median NIHSS score improved from 18 on admission to 10 at discharge, and the median mRS at discharge was 4; the latter was even lower in patients who reached a target volumeâ≤â15 mL at the end of local lysis. The in-hospital mortality rate was 8.2%, and catheter/local lysis-associated complications occurred in 5.5% of patients. Conclusion: Bedside catheter aspiration with subsequent urokinase irrigation is a safe and feasible procedure for treating spontaneous supratentorial ICH, and can immediately reduce the mass effects of haemorrhage. Additional controlled studies that assess the long-term outcome and generalizability of our findings are therefore warranted. Clinical trial registration: [www.drks.de], identifier [DRKS00007908].
RESUMO
We describe the case of a 70-year-old lady who presented to a district general hospital during an evening with fevers, feeling generally unwell. She was found to have weakness in her left upper limb and went on to have tonic-clonic seizures whilst in the Accident and Emergency Department. CT scan of the brain showed subarachnoid haemorrhage, in absence of headache, in the right frontal, superior parietal and left occipital regions. Her C-reactive protein level was elevated at 426 mg/L and her urine dip was normal. Chest radiograph showed small bilateral pleural effusions. In addition to the above-mentioned findings on clinical examination, she also had pansystolic murmur although did not have any other feature of infective endocarditis (IE). In view of the above findings, normal chest examination and no urinary symptoms, the decision was made to treat this as a case of IE empirically. She subsequently went into fast atrial fibrillation requiring direct current (DC) cardioversion and intensive care unit admission due to hypotension. The next day, echocardiography confirmed vegetations and blood cultures were positive for Staphylococcus aureus. Her MRI scan of the brain confirmed parenchymal haemorrhages and haemorrhagic infarcts. She completed a 6-week course of antibiotics and clinically improved. Despite being critically unwell, appropriate antibiotics were initiated within hours of her admission in view of clinical suspicion of underlying IE, which aided her recovery.
RESUMO
PURPOSE: Apoptotic changes in brain samples have been found in haematoma areas of patients with spontaneous intracerebral haemorrhage (SIH) undergoing surgical haematoma evacuation. However, circulating caspase-8 concentrations in SIH patients have not been described. Thus, we carried out this study with the aim to explore whether there is an association of circulating caspase-8 concentrations and mortality in patients with SIH. METHODS: We included patients with severe and supratentorial SIH. We established that the SIH was severe if Glasgow Coma Scale (GCS) was lower than 9. Intensive Care Units from 5 Spanish hospitals carried out the recruitment of patients of this observational and prospective study. We registered serum caspase-8 levels at moment of severe SIH diagnosis and 30-day mortality. RESULTS: Surviving (n = 41) in respect to non-surviving SIH patients (n = 38) showed lower serum caspase-8 levels (p < 0.001). The area under the curve to estimate 30-day mortality ability by serum caspase-8 levels was 0.75 (95% CI = 0.64-86; p < 0.001). Kaplan-Meier analysis found that patients with serum caspase-8 levels > 17.8 ng/mL showed higher death risk (Hazard ratio = 3.9; 95% CI = 1.99-7.63; p < 0.001). Multiple logistic regression analysis revealed the association of serum caspase-8 concentrations (controlling for intracerebral haemorrhage score, midline shift and early haematoma evacuation) with mortality at 30 days (Odds Ratio = 1.048; 95% CI = 1.018-1.079; p = 0.002). CONCLUSIONS: The association of serum caspase-8 concentrations with mortality of SIH patient mortality is the main of novel findings that have been revealed in our study.

INTRODUCTION: Spontaneous intracerebral haemorrhage (ICH) is associated with high mortality and high morbidity, including seizures. Seizure prophylaxis is "not recommended" by the American Stroke Association, but practice variation still exists due to inconclusive data. We performed a meta-analysis to assess the current relevant literature to determine the efficacy of seizure prophylaxis following ICH. METHODS: We performed searches of PubMed, Scopus, and Embase up to September 15, 2020. We included observational and randomized controlled studies reporting seizure prophylaxis and occurrence in adults with ICH. Outcomes were seizures, as defined by the authors, within 14 days of ICH and at the longest point of follow-up. We used random-effects models to estimate the odds ratios (ORs) for seizure prophylaxis and outcomes. The PROSPERO registration was CRD42019140493. RESULTS: We included 8 studies (2852 patients) in our analysis. The mean (± standard deviation) age of the pooled patients was 65 (±4) years; 39 % (± 5%) were female. Seizure prophylaxis did not prevent seizures at the longest follow-up time (OR 0.708, 95 % CI 0.438-1.143, pâ¯=â¯0.158, I2â¯=â¯34 %). This result was confirmed in subgroup analyses using categorical variables and in meta-regressions using continuous variables. Additionally, seizure prophylaxis was not associated with preventing early seizures, defined as < 14 days of ICH (OR 0.66, 95 % CI 0.21-2.08, pâ¯=â¯0.48, I2â¯=â¯35 %). CONCLUSION: Seizure prophylaxis following ICH was not associated with seizure prevention in adults. Most included studies were observational. Further randomized controlled trials examining the efficacy of seizure prophylaxis in high-risk patients and different types of antiepileptic drugs are needed.

OBJECTIVE: Decompressive hemicraniectomy (DH) effectively alleviates increased intracranial pressure (ICP) in patients with traumatic brain injury (TBI) and malignant middle cerebral artery (MCA) infarction. Its role in the management of spontaneous intracranial hemorrhage (SICH) however remains uncertain. This study aims to review the efficacy and safety of DH without clot evacuation in SICH. PATIENTS AND METHODS: A systematic literature search of PubMEd, EMBASE, Scopus and Cochrane Library Central Register of Control Trials was performed. Studies were reviewed independently for methodology, inclusion and exclusion criteria and end points. Primary endpoint was overall mortality. Secondary endpoint was functional outcome using modified Rankin scale (mRs) or Glasgow outcome scale (GOS). RESULTS: Nine studies with a total of 146 patients who underwent DH without clot evacuation include: 1 RCT, 3 cohort, 2 case series, and 3 case-control studies. Age range was 40-60 years, with majority of patients presenting with a relatively depressed preoperative sensorium (GCS 6-8), large hematoma volumes (>50â¯mL), and deep locations (basal ganglia and thalamus). Pooled analysis showed a favorable outcome in 53 %, a mortality rate of 26 % and a complication rate of 35.8 %. CONCLUSION: DH without clot evacuation may offer functional and mortality benefit in patients with spontaneous ICH, based on limited and heterogeneous studies.

BACKGROUND: There is uncertainty about the clinical benefit of admission to critical care after spontaneous intracerebral haemorrhage (ICH). PURPOSE: We investigated factors associated with critical care admission after spontaneous ICH and evaluated associations between critical care and 6-month functional outcome. METHODS: We included 825 patients with acute spontaneous non-traumatic ICH, recruited to a prospective multicenter observational study. We evaluated the characteristics associated with critical care admission and poor 6-month functional outcome (modified Rankin Scale, mRS > 3) using univariable (chi-square test and Wilcoxon rank-sum test, as appropriate) and multivariable analysis. RESULTS: 286 patients (38.2%) had poor 6-month functional outcome. Seventy-seven (9.3%) patients were admitted to critical care. Patients admitted to critical care were younger (p < 0.001), had lower GCS score (p < 0.001), larger ICH volume (p < 0.001), more often had intraventricular extension (p = 0.008) and underwent neurosurgery (p < 0.001). Critical care admission was associated with poor functional outcome at 6 months (39/77 [50.7%] vs 286/748 [38.2%]; p = 0.034); adjusted OR 2.43 [95%CI 1.36-4.35], p = 0.003), but not with death (OR 1.29 [95%CI 0.71-2.35; p = 0.4). In ordinal logistic regression, patients admitted to critical care showed an OR 1.47 (95% CI 0.98-2.20; p = 0.07) for a shift in the 6-month modified Rankin Scale. CONCLUSIONS: Admission to critical care is associated with poor 6-month functional outcome after spontaneous ICH but not with death. Patients admitted to critical care were a priori more severely affected. Although adjusted for main known predictors of poor outcome, our findings could still be confounded by unmeasured factors. Establishing the true effectiveness of critical care after ICH requires a randomised trial with clinical outcomes and quality of life assessments.

INTRODUCTION: Spontaneous intracerebral haemorrhage (sICH) is a severe stroke subtype. The effective therapies for patients with sICH are still unclear, and the role of surgical treatment in sICH management is still controversial. Although some large trials did not show that surgery could benefit patients with sICH, some other studies suggested that some specific surgical strategies can have potential benefits to these patients. For a better understanding of the surgical treatment in patients with sICH, it is necessary to conduct a network meta-analysis to compare the effects of medical treatment and different surgical methods comprehensively. METHODS AND ANALYSIS: This protocol has been reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Related studies until August 2018 will be searched in the following databases: PubMed, Embase, Scopus, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP and Wanfang. Randomised controlled trials and non-randomised prospective studies comparing at least two different interventions in patients with sICH will be included. Quality assessment will be conducted using Cochrane Collaboration's tool or Newcastle-Ottawa Scale based on their study designs. The primary outcome will be functional outcome and the secondary outcome will be mortality. Pairwise and network meta-analysis will be conducted using STATA V.14 (StataCorp, College Station, Texas, USA). Mean ranks and the surface under the cumulative ranking curve will be used to evaluate every intervention. Statistical inconsistency assessment, subgroup analysis, sensitivity analysis and publication bias assessment will be performed. ETHICS AND DISSEMINATION: Ethics approval is not necessary because this study will be based on publications. The results of this study will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42018112239.

BACKGROUND: Spontaneous intracerebral haemorrhage (SICH) is a common condition with high morbidity and mortality. Segmentation of haematoma and perihaematoma oedema on medical images provides quantitative outcome measures for clinical trials and may provide important markers of prognosis in people with SICH. METHODS: We take advantage of improved contrast seen on magnetic resonance (MR) images of patients with acute and early subacute SICH and introduce an automated algorithm for haematoma and oedema segmentation from these images. To our knowledge, there is no previously proposed segmentation technique for SICH that utilises MR images directly. The method is based on shape and intensity analysis for haematoma segmentation and voxel-wise dynamic thresholding of hyper-intensities for oedema segmentation. RESULTS: Using Dice scores to measure segmentation overlaps between labellings yielded by the proposed algorithm and five different expert raters on 18 patients, we observe that our technique achieves overlap scores that are very similar to those obtained by pairwise expert rater comparison. A further comparison between the proposed method and a state-of-the-art Deep Learning segmentation on a separate set of 32 manually annotated subjects confirms the proposed method can achieve comparable results with very mild computational burden and in a completely training-free and unsupervised way. CONCLUSION: Our technique can be a computationally light and effective way to automatically delineate haematoma and oedema extent directly from MR images. Thus, with increasing use of MR images clinically after intracerebral haemorrhage this technique has the potential to inform clinical practice in the future.

OBJECTIVES: Surgical treatment is widely used for haematoma removal in spontaneous intracerebral haemorrhage (ICH) patients, but there is controversy about the selection of surgical methods. The CT angiography (CTA) spot sign has been proven to be a promising factor predicting haematoma expansion and is recommended as an entry criterion for haemostatic therapy in patients with ICH. This trial was designed to evaluate the clinical efficacy of two surgical methods (haematoma removal by craniotomy and craniopuncture combined with urokinase infusion) for patients in the early stage (≤6h from symptom onset) of spontaneous ICH with a moderate haematoma volume (30â¯mlâ¯-â¯60â¯ml). PATIENTS AND METHODS: From January 2012 to July 2017, 196 eligible patients treated in our institution were enrolled according to the inclusion criteria. The patients were divided into the CTA spot sign positive type and CTA spot sign negative type according to the presence or absence of the CTA spot sign. For each type, the patients were randomly assigned to two groups, i.e., the craniotomy group, in which patients underwent craniotomy with haematoma removal, and the craniopuncture group, in which patients underwent minimally invasive craniopuncture combined with urokinase infusion therapy. Neurological function was evaluated with the Scandinavian Stroke Scale (SSS) at day 14. The disability level and the activities of daily living were assessed using a modified Rankin Scale (mRS) and Barthel Index (BI) at day 90. Case fatalities were recorded at day 14 and 90. Complications were recorded during hospitalization. RESULTS: For the CTA spot sign positive type, the craniotomy group had a higher SSS than that in the craniopuncture group (Pâ¯<â¯0.05) at day 14. The rebleeding rate was higher in the craniopuncture group than that in the craniotomy group (Pâ¯<â¯0.05) during hospitalization. The craniotomy group had a lower mRS than that in the craniopuncture group (Pâ¯<â¯0.01) and had a higher BI than that in the craniopuncture group (Pâ¯<â¯0.05) at day 90. There was no statistically significant difference in the fatality rate between the two groups. For the CTA spot sign negative type, there were no significant differences in the SSS, mRS, BI, fatality rate and complication rate between the two groups. CONCLUSION: ICH can be divided into the CTA spot sign positive and negative type according to the presence or absence of the CTA spot sign. For the CTA spot sign positive type, patients can benefit from craniotomy with haematoma removal, which can reduce the postoperative rebleeding rate and improve the prognosis. For the CTA spot sign negative type, both craniotomy and craniopuncture are applicable. Considering simple procedure and minor surgical injury, craniopuncture can be a more reasonable choice.

BACKGROUND: Management of spontaneous intracerebral haemorrhage (SICH) is still an enigma. The study was conducted to find out the most appropriate mode of treatment and other possible inclusion criteria's in addition to clot size. METHODS: Sixty consecutive patients of SICH excluding bleeds due to arteriovenous malformations/aneurysm were included in the study. Patients with moderate and large bleeds, progressive neurological deficit and glasgow coma scale (GCS) of more than five were included in the surgical group and rest treated conservatively. RESULT: Location of the bleed, other co-morbid conditions and GCS at presentations were more important guidelines than size of the bleed. Mortality was more in surgically treated group where cerebellar bleed fared well after evacuation. CONCLUSION: Surgery is preferred in superficially located bleeds and cerebellar bleeds. Intra cranial pressure monitoring will help in categorizing the mode of treatment better than mere clot size.
RESUMO
RATIONALE: Aside from blood pressure lowering, treatment options for intracerebral haemorrhage remain limited and a proportion of patients will undergo early haematoma expansion with resultant significant morbidity and mortality. Tranexamic acid (TXA), an anti-fibrinolytic drug, has been shown to significantly reduce mortality in patients, who are bleeding following trauma, when given rapidly. TICH-2 is testing whether TXA is effective at improving outcome in spontaneous intracerebral haemorrhage (SICH). METHODS AND DESIGN: TICH-2 is a pragmatic, phase III, prospective, double-blind, randomised placebo-controlled trial. Two thousand adult (aged ≥ 18 years) patients with an acute SICH, within 8 h of stroke onset, will be randomised to receive TXA or the placebo control. The primary outcome is ordinal shift of modified Rankin Scale score at day 90. Analyses will be performed using intention-to-treat. RESULTS: This paper and its attached appendices describe the statistical analysis plan (SAP) for the trial and were developed and published prior to database lock and unblinding to treatment allocation. The SAP includes details of analyses to be undertaken and unpopulated tables which will be reported in the primary and key secondary publications. The database will be locked in early 2018, ready for publication of the results later in the same year. DISCUSSION: The SAP details the analyses that will be done to avoid bias arising from prior knowledge of the study findings. The trial will determine whether TXA can improve outcome after SICH, which currently has no definitive therapy. TRIAL REGISTRATION: ISRCTN registry, ID: ISRCTN93732214 .

Spontaneous intracerebral haemorrhage (SICH) is a rare occurrence in children, with different aetiological factors, clinical characteristics and prognosis. A 14 year male child had sudden onset of headache associated with multiple vomiting. Magnetic resonance imaging showed deep seated intracerebral haematoma. Haematoma was evacuated successfully and child recovered without deficits. A high index of suspicion is necessary for the diagnosis of spontaneous intracerebral haemorrhage in children.
