Abstract
There are few studies regarding imaging markers for predicting postoperative rebleeding after stereotactic minimally invasive surgery (MIS) for hypertensive intracerebral haemorrhage (ICH), and little is known about the relationship between satellite sign on computed tomography (CT) scans and postoperative rebleeding after MIS. This study aimed to determine the value of the CT satellite sign in predicting postoperative rebleeding in patients with hypertensive ICH who undergo stereotactic MIS. We retrospectively examined and analysed 105 patients with hypertensive ICH who underwent standard stereotactic MIS for hematoma evacuation within 72 h following admission. Postoperative rebleeding occurred in 14 of 65 (21.5%) patients with the satellite sign on baseline CT, and in 5 of the 40 (12.5%) patients without the satellite sign. This difference was statistically significant. Positive and negative values of the satellite sign for predicting postoperative rebleeding were 21.5% and 87.5%, respectively. Multivariate logistic regression analysis verified that baseline ICH volume and intraventricular rupture were independent predictors of postoperative rebleeding. In conclusion, the satellite sign on baseline CT scans may not predict postoperative rebleeding following stereotactic MIS for hypertensive ICH.

Abstract
Spontaneous intracerebral hemorrhage (ICH) is a devastating form of stroke, with a high rate of mortality and morbidity. Even with the best current medical or surgical interventions, outcomes remain poor. The location and initial hematoma volume are strong predictors of mortality. Hematoma expansion (HE) is a further marker of poor prognosis that may be at least partly preventable. Several risk factors for HE have been identified, including baseline ICH volume, anticoagulation, and computed tomography angiography spot signs. Recent studies have shown the correlation of serum calcium (Ca++) levels on admission with HE. Low serum Ca++ level has been associated with larger hematoma volume at the time of presentation, HE, and worse outcome. Although the causal and mechanistic links between low serum Ca++ level and HE are not well understood, several mechanisms have been proposed including coagulopathy, platelet dysfunction, and higher blood pressure (BP) in the context of low serum Ca++ level. However, low serum Ca++ level might be only a biomarker of the adaptive response due to acute inflammatory response following acute ICH. The purpose of the current review is to discuss the evidence regarding the possible role of low serum Ca++ level on HE in acute ICH.

Abstract
Background Tight blood pressure control is critical in neurosurgical patients. Systolic blood pressure (SBP) must be low enough to avoid injury and minimize intraparenchymal hemorrhage (IPH) but high enough to maintain cerebral perfusion. American Heart Association (AHA) guidelines recommend SBP <140 in intracerebral hemorrhage. This paper sought to elucidate the effect of early control of SBP on IPH expansion. Methods 134 patients with spontaneous IPH between 2011 and 2015 were analyzed utilizing chart review. Initial versus follow-up bleed size, presentation and discharge condition, discharge disposition, and blood pressure control adequacy were analyzed using the generalized linear model. Results Altered mental status was the most common presenting complaint (78%). Presenting GCS failed to demonstrate a significant main effect. Age, initial IPH volume, presenting SBP, and one-hour SBP significantly affected IPH percent expansion (p=0.002, =0.002, <0.0005, and =0.026). Several two-way interactions affected IPH percent change implying synergistic effects of the predictor variables. Conclusion Patients aged 60-70 years had the largest percent IPH expansion followed by patients aged 20-30 years. Initial IPH volume of 65.23-78.26 ml showed the largest expansion. Initial IPH volume of 52.18-65.22 ml demonstrated the least percentage of IPH expansion. One-hour control of SBP to binned groups of 111-121 mmHg or 121-132 mmHg portends relative minima in bleed expansion corresponding with AHA recommendations for IPH patients. This study suggests that this degree of early and aggressive control of SBP is achievable, safe, and may minimize IPH expansion. Future studies are needed to elucidate the role of co-morbidities and to confirm these findings in broader populations.

Abstract
BACKGROUND Hematoma expansion after acute spontaneous intracerebral hemorrhage (ICH) is well established to result in poor prognosis. Recent studies have demonstrated that the ABO blood type system has potential implications on hemostatic properties. The purpose of this study was to explore the potential association of blood type O with hematoma expansion in patients with ICH and validate the usefulness in predicting early hematoma expansion. METHODS We retrospectively enrolled consecutive patients with ICH who underwent baseline computed tomographic (CT) scan within 6 hours after onset of symptoms. The follow-up CT scan was available within 48 hours after the baseline CT scan. Hematoma expansion was defined as total volume increase more than 33% or more than 6 mL. We performed univariate and multivariate logistic regression analyses to investigate the relationship between the different types of blood (type O versus other types) and hematoma expansion. RESULTS A total of 210 patients were included in the study. Among them, 72 patients (34.3%) carried blood type O. Hematoma expansion was more common in patients with blood type O (41.7%) than those with other blood types (18.1%; P < .001). Furthermore, the time to baseline CT scan, blood type O, and admission Glasgow Coma Scale score were demonstrated to be independent predictors of hematoma expansion in multivariate logistic regression analysis model. The sensitivity, specificity, positive, and negative predictive values of blood type O for predicting hematoma expansion were 54.5%, 72.9%, 41.6%, and 81.9%, respectively. CONCLUSIONS Our findings suggest that blood type O represents an independent predictor of hematoma expansion after ICH. Hemostasis seems to be involved in expansion and may represent an important treatment target.

Computed Tomographic Black Hole Sign Predicts Postoperative Rehemorrhage in Patients with Spontaneous Intracranial Hemorrhage Following Stereotactic Minimally Invasive Surgery. World Neurosurg 2018; 120:e153-e160.

Abstract
OBJECTIVES Determining the value of the computed tomographic black hole sign in predicting postoperative rehemorrhage in patients with intracranial hemorrhage (ICH) underwent minimally invasive surgery (MIS). METHODS Two hundred ninety-five patients with spontaneous ICH underwent stereotactic MIS within 24 hours after admission. Ninety-eight patients (33%) demonstrated a black hole sign on initial computed tomography (CT). Postoperative rehemorrhage occurred in 68 patients (named the rehemorrhage group, including patients with and without black hole sign) and the other 227 patients (non-rehemorrhage group) did not show rehemorrhage. Multivariable logistic regression analyses were performed to assess the values of the black hole sign. RESULTS Postoperative rehemorrhage occurred in 57 of the 98 (58.2%) patients with the black hole sign, and in 11 of the 197 (5.58%) patients without the black hole sign. In the rehemorrhage group, 39 patients (57.4%) were found to have the black hole sign. However, only 59 patients (25.99%) from the non-rehemorrhage group showed the black hole sign. The sensitivity, specificity, and positive and negative predictive values of the black hole sign for predicting postoperative rehemorrhage were 57.4%, 74%, 39.8%, and 85.3%, respectively. The odd ratio for the black hole sign, the hematoma irregularity, and the CT value for predicting the postoperative rehemorrhage were 10.501, 9.631, and 4.750, respectively. CONCLUSIONS The black hole sign on initial CT could predict the postoperative rehemorrhage following the minimally invasive procedures.

Abstract
The optimal target of blood pressure (BP) in the acute phase of intracranial haemorrhage (ICH) is still controversial. Our aim was to evaluate safety and efficacy of intensive BP lowering compared to standard BP treatment in ICH. We conducted a systematic review and meta-analysis of all available randomized controlled trials recruiting patients with elevated BP in acute spontaneous ICH to intensive or standard BP-lowering treatment. Our primary outcomes were 3-month mortality, disability (modified Rankin Scale 3-5) and combined death or disability. Secondary outcomes were early neurological deterioration at 24 h, substantial haematoma enlargement within 24-72 h and 3-month non-fatal serious adverse events. We included six studies for a total of 4385 patients (mean age 62 years, 62.3% men). No differences were detected between the two treatment groups in 3-month mortality (RR = 0.99, 95% CI 0.83-1.17), disability (RR = 0.96, 95% CI 0.89-1.03) and combined death and disability (RR = 0.97, 95% CI 0.90-1.03). The rate of patients with early neurological deterioration, substantial haematoma enlargement and non-fatal serious adverse events was similar in the two treatment groups (RR = 1.03, 95% CI 0.88-1.19, RR = 0.85, 95% CI 0.70-1.03, RR = 1.07, 95% CI 0.90-1.28, respectively). An intensive BP control in the acute phase of ICH is not beneficial and should not be recommended. Therefore, the systolic BP target of less than 140 mmHg that is now suggested by guidelines needs to be reconsidered.

Abstract
Stroke is a leading cause of morbidity and mortality worldwide, and consists of two types, ischemic and hemorrhagic. Currently, there is no effective treatment to increase the survival rate or improve the quality of life after ischemic and hemorrhagic stroke in the subacute to chronic phases. Therefore, it is necessary to establish therapeutic strategies to facilitate functional recovery in patients with stroke during both phases. Cell-based therapies, using microglia and monocytes/macrophages preconditioned by optimal stimuli and/or any therapies targeting these cells, might be an ideal therapeutic strategy for managing stroke. Microglia and monocytes/macrophages polarize to the classic pro-inflammatory type (M1-like) or alternative protective type (M2-like) by optimal condition. Cell-based therapies using M2-like microglia and monocytes/macrophages might be protective therapeutic strategies against stroke for three reasons. First, M2-like microglia and monocytes/monocytes secrete protective remodeling factors, thus prompting neuronal network recovery via tissue (including neuronal) and vascular remodeling. Second, these cells could migrate to the injured hemisphere through the blood–brain barrier or choroid–plexus. Third, these cells could mitigate the extent of inflammation-induced injuries by suitable timing of therapeutic intervention. Although future translational studies are required, M2-like microglia and monocytes/macrophages therapies are attractive for managing stroke based on their protective functions.

Abstract
BACKGROUNDS Intracranial post-operative re-haemorrhage is an important complication in patients with hypertensive intracerebral haemorrhage (ICH). The purpose of the present study was to determine the value of the computed tomography (CT) blend sign in predicting post-operative re-haemorrhage in patients with ICH. METHODS A total of 126 patients with ICH were included in the present study. All the patients underwent standard stereotactic minimally invasive surgery(MIS) to remove the ICH within 24 h following admission. There were 41 patients with a blend sign on initial CT and 85 patients without a blend sign on the initial CT. Multivariable logistic regression analyses were performed to assess the relationship between the presence of the blend sign on the non-enhanced admission CT scan and post-operative re-haemorrhage. RESULTS Post-operative re-haemorrhage occurred in 24 of the 41 patients with the blend sign, and in 9 of the 85 patients without the blend sign. The incidence of re-haemorrhage was significantly different between the groups. The multivariate logistic regression analysis demonstrated that the initial Glasgow coma scale score (p = 0.002) and blend sign (P < 0.00) on the initial CT scan are independent predictors of post-operative re-haemorrhage. The sensitivity, specificity, and positive and negative predictive values of the blend sign for predicting post-operative re-haemorrhage were 72.7, 81.7, 58.5 and 89.4%, respectively. CONCLUSIONS The presence of the blend sign on the initial CT scan is closely associated with post-operative re-haemorrhage in patients with ICH who undergo stereotactic MIS.

Abstract
As one of the most lethal stroke subtypes, intracerebral hemorrhage (ICH) is acknowledged as a serious clinical problem lacking effective treatment. Available evidence from preclinical and clinical studies suggests that inflammatory mechanisms are involved in the progression of ICH-induced secondary brain injury. High mobility group box-1 (HMGB1) is a ubiquitous and abundant nonhistone DNA-binding protein, and is also an important proinflammatory molecule once released into the extracellular space from the nuclei. Here, we show that treatment with neutralizing anti-HMGB1 mAb (1 mg/kg, i.v. twice) remarkably ameliorated ICH-injury induced by local injection of collagenase IV in the striatum of rats. Administration of anti-HMGB1 mAb inhibited the release of HMGB1 into the extracellular space in the peri-hematomal region, reduced serum HMGB1 levels and decreased brain edema by protecting blood-brain barrier integrity, in association with decreased activated microglia and the expression of inflammation-related factors at 24 h after ICH. Consequently, anti-HMGB1 mAb reduced the oxidative stress and improved the behavioral performance of rats. These results strongly indicate that HMGB1 plays a critical role in the development of ICH-induced secondary injury through the amplification of plural inflammatory responses. Intravenous injection of neutralizing anti-HMGB1 mAb has potential as a novel therapeutic strategy for ICH.
