Abstract
Objective This work focused on investigating if robot-assisted minimally invasive surgery improved middle term vital outcome for primary brainstem hemorrhage (PBSH). Methods This work obtained clinical data from patients with PBSH admitted from July 2019 to August 2021. All cases were classified as surgical or conservative treatment group. The general information, Glasgow coma scale (GCS) score, Glasgow outcome score (GOS), along with survival time in patients 60 days after robot-assisted surgery were recorded and analyzed. Results A prospective analysis was performed on 82 cases meeting eligibility criteria, including 36 from surgical group whereas 46 from the conservative group. Sixty days after onset, the death rate was found to be 19.44% and 50.00% of surgical and conservative groups, separately (cases versus controls, P < 0.05). Furthermore, postoperative GOS and GCS scores of surgical group were significantly higher, and hydrocephalus was lower compared with conservative group. Central fever incidence did not exhibit any significant difference between two groups. Conclusion Robot-assisted PBSH drainage may improve survivorship and reduce the occurrence of hydrocephalus.

Abstract
Objective Spontaneous hypertensive brainstem hemorrhage (HBSH) is characterized by sudden onset, rapid progression and poor prognosis. There has been a growing tendency of surgical treatment for HBSH. This study aimed to investigate outcomes and potential factors associated with the prognosis of robot-assisted drainage surgery for HBSH treatment. Methods Patients with HBSH from July 2016 to March 2023 at a single neurosurgery center were included and divided into conservative group and surgical groups. Baseline and clinical data, radiographic characteristics, complications, and outcome evaluations were recorded and analyzed. Results A total of 125 patients, with 74 in the conservative group and 51 in the surgical group, were enrolled in the study. Mortality at 6 months was 59/74 (79.7%) in the conservative group and 9/51 (17.6%) in the surgical group. Twenty-four patients (47.1%) achieved favorable outcomes in the surgical group, whereas this rate in the conservative group was only 5.4% (4/74). There was a significant difference in NIHSS, GCS, and mRS at 6 months between surviving patients in the conservative and surgical groups. In prognostic analysis in the surgical subgroup, initial GCS score [5 (IQR 4-7) vs. 3 (IQR 3-4), p < 0.001], NIHSS [36 (IQR 32-38) vs. 40 (IQR 38-40), p < 0.001], smoking history [45.8% (11/24) vs. 74.1% (20/27), p = 0.039], hematoma volume [6.9 (IQR 6.2-7.6) vs. 9.6 (IQR 7.3-11.4), p = 0.001], and hemorrhage location (p = 0.001) were potential risk factors for poor 6-month prognosis after robot-assisted surgery for HBSH. Conclusion Based on the results of this study, robot-assisted minimally invasive drainage of brain stem hematoma may significantly reduce mortality and improve prognosis. Surgery should be conducted for selected patients.

Abstract
OBJECTIVE To explore the effect of stereotactic aspiration surgery and conventional treatment for primary brainstem haemorrhage. METHODS The clinical data of 137 patients with primary brain stem haemorrhage (haematoma volume > 3 ml) from August 2014 to August 2022 at the First Hospital of Hebei Medical University were reviewed. Sixty-five patients were treated with stereotactic haematoma aspiration, and 72 patients were treated with conventional therapy. We followed up on patient survival after 30 days and the recovery of neurological function after 90 days. The recovery of neurological function was evaluated by the modified Rankin Scale (mRS) 90 days after treatment. The mortality and neurological recovery rates of the two treatments were compared and analysed. RESULTS There was a significant difference in the 30-day mortality rate between the two treatment groups (p < 0.05). There was a significant difference in neurological function improvement after 90 days between the two treatment groups (P < 0.05). There was no significant difference between stereotactic aspiration and routine treatment in the prognosis of primary brainstem haemorrhage patients at 90 days after treatment (P > 0.05). CONCLUSION Stereotactic aspiration surgery for primary brain stem haemorrhage can significantly reduce mortality and improve the neurological function of some patients.

Abstract
Purpose Spontaneous intracerebral hemorrhage (ICH) cases caused by hypertension often have poor prognoses. The use of dehydrant agents, such as mannitol, is common to reduce intracranial pressure and alleviate cerebral edema, but they may also pose a risk of worsening kidney function. This study aimed to investigate the impact of impaired kidney function on the outcomes of surgically treated hypertensive ICH patients. Methods We conducted a retrospective analysis of a consecutive cohort of patients who underwent surgical intervention due to hypertension-related ICH at our institute between December 1, 2017, and January 31, 2022. Demographic, clinical, radiological, and prognostic data were collected. Patients were categorized into two groups based on 90-day mortality: group A [overall survival (OS) ≤3 months] and group B (OS >3 months). Survival analysis was performed to identify factors associated with poor outcomes. Results Among the 232 eligible patients, group A exhibited significantly impaired kidney function, as indicated by mean estimated glomerular filtration rate (eGFR) at admission, postoperative, 3-day postoperative, and 7-day postoperative time points (91.9, 82.5, 73.5, 75.2 ml/min/1.73 m²). In contrast, group B did not show significant changes in kidney function (mean eGFR for the corresponding time points: 108.1, 106.5, 111.5, 109.6 ml/min/1.73 m²). The 3-day postoperative eGFR showed the strongest predictive ability for assessing prognosis [areas under the curve (AUC): 0.617, 0.675, 0.737, 0.730]. Univariate and multivariate analyses identified low Glasgow Coma Scale (GCS) score (3-8), ventricle intrusion of hematomas, cardiac failure, larger hematoma volume, infection, and lower 3-day postoperative eGFR as adverse factors for survival. Conclusions Preserving kidney function is crucial for achieving favorable outcomes in hypertensive ICH cases. Impaired 3-day postoperative eGFR emerged as an independent risk factor for overall survival. Patients with cardiac failure, infection, and larger hematoma volume should receive careful management to improve outcomes.

Abstract
Objective The purpose of this study is to investigate the effect of hematoma volume on the 30-Day Mortality Rate of patients with Primary Hypertensive Brainstem Hemorrhage (PHBH). Methods Retrospective analysis was done on the clinical information of 74 patients who underwent treatment for primary hypertensive brainstem hemorrhage at the Department of Neurosurgery of the 908th Hospital of the Joint Logistic Support Force of the Chinese People's Liberation Army between January 2018 and December 2021. Both univariate and multivariate logistic regression were used to assess clinical signs and risk factors that affect 30-day mortality. Results In the 74 patients with primary hypertensive brainstem hemorrhage included in this investigation, 46 patients died and 28 patients survived. The mortality rate at 30 days was 62.16%. A statistically significant difference was seen (P < 0.001) in the results of the univariate analysis, which suggested that hematoma volume may be a factor affecting the prognosis of patients with hypertensive brainstem hemorrhage. Hematoma volume was further demonstrated to be a risk factor and an independent factor impacting death in patients with brainstem hemorrhage (P < 0.001) by multivariate logistic regression analysis (OR: 2.6, 95% CI: 1.7-3.9, P < 0.001 Crude Model, OR: 3.6, 95% CI: 1.7-7.7, P < 0.001 Multivariate-Adjusted Model). After adjusting for confounding variables such as age, body mass index, sex, history of diabetes mellitus, history of hypertension, admission GCS score, stereotactic aspiration, combined hydrocephalus, admission systolic and diastolic blood pressure, the hematoma volume was revealed to be an independent predictor of 30-day death in patients with brainstem hemorrhage. We discovered by smooth curve fitting that hematoma volume increased in a non-linear manner with 30-day mortality. The 30-day mortality rate did not alter significantly when the hematoma volume was less than 4 ml. When the hematoma volume was greater than 4 ml, the 30-day mortality rate increased rapidly, and when the hematoma volume was 10 ml, the 30-day mortality rate reached the maximum. Conclusions Hematoma volume is an independent factor affecting 30-day mortality in patients with primary hypertensive brainstem hemorrhage. The severe and extensive neurological damage caused by primary hypertensive brainstem hemorrhage is highly unlikely to be fundamentally altered by a single protocol, and new avenues need to be explored scientifically and continuously.

Abstract
Cerebral cavernous malformations (CCMs) arise when capillaries within the brain enlarge abnormally, causing the blood-brain barrier (BBB) to break down. The BBB serves as a sophisticated interface that controls molecular interactions between the bloodstream and the central nervous system. The neurovascular unit (NVU) is a complex structure made up of neurons, astrocytes, endothelial cells (ECs), pericytes, microglia, and basement membranes, which work together to maintain blood-brain barrier (BBB) permeability. Within the NVU, tight junctions (TJs) and adherens junctions (AJs) between endothelial cells play a critical role in regulating the permeability of the BBB. Disruptions to these junctions can compromise the BBB, potentially leading to a hemorrhagic stroke. Understanding the molecular signaling cascades that regulate BBB permeability through EC junctions is, therefore, essential. New research has demonstrated that steroids, including estrogens (ESTs), glucocorticoids (GCs), and metabolites/derivatives of progesterone (PRGs), have multifaceted effects on blood-brain barrier (BBB) permeability by regulating the expression of tight junctions (TJs) and adherens junctions (AJs). They also have anti-inflammatory effects on blood vessels. PRGs, in particular, have been found to play a significant role in maintaining BBB integrity. PRGs act through a combination of its classic and non-classic PRG receptors (nPR/mPR), which are part of a signaling network known as the CCM signaling complex (CSC). This network couples both nPR and mPR in the CmPn/CmP pathway in endothelial cells (ECs).

Abstract
ObjectiveRecently, short-term spinal cord stimulation (st-SCS) has been used in neurorehabilitation and consciousness recovery. However, little is known about its effects on primary brainstem hemorrhage (PBSH)-induced disorders of consciousness (DOC). In this study, we examined the therapeutic effects of st-SCS in patients with PBSH-induced DOC.MethodsFourteen patients received a 2-week st-SCS therapy. Each patient's state of consciousness was evaluated using the Coma Recovery Scale-Revised (CRS-R). CRS-R evaluation scores were recorded at the baseline (before SCS implantation) and 14 days later.ResultsOver 70% (10/14) of the patients (CRS-R score increased to ≥2 points) responded to the SCS stimulation after 14 days of st-SCS treatment. All items included in the CRS-R exhibited a significant increase post-treatment compared with pretreatment. After 2 weeks of st-SCS treatment, seven patients showed diagnostic improvement, resulting in a 50% (7/14) overall effective rate. Approximately 75% (3/4) of patients with minimally conscious state plus (MCS+) improved to emergence from MCS (eMCS), and 50% (1/2) of patients with vegetative state or unresponsive wakefulness syndrome (VS/UWS) improved to MCS+.ConclusionIn PBSH-induced DOC, st-SCS is a safe and effective treatment. The clinical behavior of the patients improved significantly following the st-SCS intervention, and their CRS-R scores markedly increased. This was most effective for MCS+.

Abstract
BACKGROUND Whether primary brainstem hemorrhage (PBH) should be treated with a conservative treatment or with surgical intervention (such as craniotomy, puncture, and drainage) is still controversial. The aim of this study was to assess the feasibility and safety of puncture and drainage for PBH with the assistance of a surgical robot. PATIENTS AND METHODS A total of 53 patients diagnosed with PBH were included in this study. They were divided into surgical and nonsurgical groups. All patients in the surgical group underwent puncture and drainage of PBH assisted with surgical robots at Beijing Jingmei General Hospital from June 2017 to January 2021. We evaluated this technology with radiographic and clinical results. RESULTS Postoperative computed tomography showed that all the drainage catheters had been pushed to the target point, which had been designated before the operation. After the operation, the hematoma was reduced by an average of 3.7 mL. None of the patients experienced serious surgery-related complications. Clinical follow-up revealed that 2 patients could not be followed-up, 8 died, and the rest were in disability or in a vegetative state. CONCLUSIONS It may be safe, feasible, and effective to complete the puncture and drainage of PBH with the assistance of a surgical robot. This technique has fewer complications than the traditional puncture method and has high accuracy. It may be more suitable for patients with a hematoma volume of 5 to 10 mL in PBH. The amount of hematoma volume >10 mL may be associated with poor postoperative prognosis. However, high-quality cohorts or case-control studies are needed to verify the effect in this study.

Abstract
PurposeBrainstem hemorrhage is usually treated conservatively with medication and has high mortality and morbidity rates. Stereotactic aspiration can directly and microinvasively draw out the hemorrhage within a narrow space in the brainstem, thus promoting quick recovery and potentially saving the life of the patient. This study was conducted to investigate the effect of stereotactic aspiration on patients with brainstem hemorrhage in a case series.Materials and methodsA total of 42 patients with brainstem hemorrhage were enrolled for stereotactic aspiration of the brain hemorrhage, and another 30 patients with brainstem hemorrhage were enrolled for conservative treatment. The clinical and imaging data were analyzed and compared.ResultsStereotactic aspiration was successful in all patients (100%), with immediate elimination of hematoma in the brainstem. In five patients with the hemorrhage extending to the fourth ventricle (n = 1) and basal ganglia (n = 4), the hemorrhage was eliminated, resulting in good outcomes. However, four patients died of multiple organ failure after aspiration, resulting in a mortality rate of 9.5%. One week after surgery, the Glasgow Coma Scale (GCS) score ranged from 3 to 11 (mean 5.9 ± 2.3). At 1-month follow-up, 4 patients died, and 36 patients survived, with the GCS score ranging between 3 and 15 (mean 8.6 ± 2.1), which was significantly (P < 0.01) higher than that before surgery. The Modified Rankin Scale (mRS) score was 5 before treatment, 5 (4.4, 6) at 1 week after surgery, and 5 (4, 6) at 1 month. In the conservative group, 16 (53.3%) patients died during hospitalization. The GCS score was 0–6 (mean 2.3 ± 1.1), which was significantly (P < 0.05) worse than at admission or of that in the aspiration group at 1 month. The mRS score at 1 month was 6 (5, 6), which was significantly (P < 0.05) worse than that in the aspiration group.ConclusionStereotactic aspiration for brainstem hemorrhage as an approach of microinvasiveness may be effective in evacuating brainstem hemorrhage and may promote quick recovery of the patient, resulting in better clinical outcomes.

Abstract
Objectives It is unclear whether surgical hematoma evacuation should be performed in cases of primary brainstem hemorrhages (PBH). Here, we analyzed 15 cases with severe primary midbrain and upper pons hemorrhages to assess the associations between the subtemporal tentorial approach and patient functional outcomes and mortality.
Design A total of 15 patients diagnosed with severe primary midbrain and upper pons hemorrhages who had previously received the subtemporal tentorial approach at our facility from January 2018 and March 2019 were analyzed. All surviving cases received a follow-up at 6 months after surgery. The Glasgow Coma Scale and Glasgow Outcome Scale (GOS) scores were analyzed 1 and 6 months after surgery, respectively. Demographic data, lesion characteristics, and follow-up data were retrospectively collected.
Results All patients successfully underwent surgical evacuation for hematomas using the subtemporal tentorial approach. The overall survival rate for these cases was 66.7% (10/15). At the last follow-up, 26.7% of patients (4/15) exhibited healthy function (GOS score: 4), 20.0% (3/15) showed disability (GOS score: 3) and 20.0% (3/15) were in a vegetative state (GOS score: 2).
Conclusions Based on the results uncovered in this study, the subtemporal tentorial approach was found to be both safe and feasible and may be beneficial for the treatment of severe primary midbrain and upper pons hemorrhages, but a more comprehensive and comparative study is required to further confirm these results.

Abstract
Symptomatic hemorrhagic transformation (HT) is one of the complications most likely to lead to death in patients with acute ischemic stroke. HT after acute ischemic stroke is diagnosed when certain areas of cerebral infarction appear as cerebral hemorrhage on radiological images. Its mechanisms are usually explained by disruption of the blood-brain barrier and reperfusion injury that causes leakage of peripheral blood cells. In ischemic infarction, HT may be a natural progression of acute ischemic stroke and can be facilitated or enhanced by reperfusion therapy. Therefore, to balance risks and benefits, HT occurrence in acute stroke settings is an important factor to be considered by physicians to determine whether recanalization therapy should be performed. This review aims to illustrate the pathophysiological mechanisms of HT, outline most HT-related factors after reperfusion therapy, and describe prevention strategies for the occurrence and enlargement of HT, such as blood pressure control. Finally, we propose a promising therapeutic approach based on biological research studies that would help clinicians treat such catastrophic complications.

Abstract
Intracerebral hemorrhage (ICH) is a devastating disease with high mortality and morbidity. Soluble epoxide hydrolase (sEH) is the key enzyme in the epoxyeicosatrienoic acids (EETs) signaling. sEH inhibition has been demonstrated to have neuroprotective effects against multiple brain injuries. However, its role in the secondary injuries after ICH has not been fully elucidated. Here we tested the hypothesis that 1-Trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl)urea (TPPU), a potent and highly selective sEH inhibitor, suppresses inflammation and the secondary injuries after ICH. Adult male C57BL/6 mice were subjected to a collagenase-induced ICH model. TPPU alleviated blood-brain barrier damage, inhibited inflammatory response, increased M2 polarization of microglial cells, reduced the infiltration of peripheral neutrophils. In addition, TPPU attenuated neuronal injury and promoted functional recovery. The results suggest that sEH may represent a potential therapeutic target for the treatment of ICH.

Abstract
Primary brainstem hemorrhage (PBSH) is the most fatal subtype of intracerebral hemorrhage and is invariably associated with poor prognosis. Several prognostic factors are involved, of which the two most predominant and consistent are the initial level of consciousness and hemorrhage size. Other predictors, such as age, hyperthermia, and hydrocephalus, are generally not dependable indicators for making prognoses. Scoring systems have now been developed that can predict mortality and functional outcomes in patients suffering from PBSH, which can thus guide treatment decision-making. A novel grading scale, entitled “the new primary pontine hemorrhage (PPH) score,” represents the latest approach in scoring systems. In this system, patients with a score of 2–3 points appear to benefit from surgical management, although this claim requires further verification. The four main surgical options for the treatment of PBSH are craniotomy, stereotactic hematoma puncture and drainage, endoscopic hematoma removal, and external ventricular drainage. Nevertheless, the management of PBSH still primarily involves conservative treatment methods and surgery is generally not recommended, according to current practice. However, the ongoing clinical trial, entitled Safety and Efficacy of Surgical Treatment in Severe Primary Pontine Hemorrhage Evacuation (STIPE), should provide additional evidence to support the surgical treatment of PBSH. Therefore, we advocate the update of epidemiological data and re-evaluation of PBSH treatment in a contemporary context.

Abstract
Primary brainstem haemorrhage (PBH) is characterized by acute onset, rapid deterioration, many complications, and poor prognosis. Its treatment has been controversial. This study aimed to explore the clinical risk factors of postoperative survival and neurological function recovery of stereotactic aspiration in the treatment of PBH. The clinical data of 65 patients with severe brainstem haemorrhage from February 2019 to February 2020 in the First Hospital of Hebei Medical University were reviewed. All patients were treated with stereotactic haematoma aspiration. We determined the survival status of patients at 30 days after the operation and the recovery of neurological function at 90 days. The modified Rankin Scale score (mRS) was used to assess the survival status. The 30-day mortality rate was 23.1% (15 patients). The proportion of patients with good neurological recovery at 90 days after the operation was 32.3% (21 patients). According to the multivariate logistic regression analysis, the haematoma classification was an independent risk factor for postoperative survival (OR = 0.197, 95% CI: 0.016-0.385, p = 0.046) and recovery of neurological function 90 days after surgery (OR = 0.019, 95% CI: 0.001-0.267, p = 0.003). The haematoma classification is an independent risk factor for 30-day mortality and recovery of neurological function 90 days after surgery. Massive and basal-tegmental haematomas were associated with higher mortality. The prognosis of patients with unilateral and bilateral tegmental haematoma was better than that of patients with other haematoma types.

Abstract
INTRODUCTION Management of spontaneous intracerebral hemorrhage (ICH) remains controversial despite efforts to produce high level evidence in the past few years. We systematically examined the pooled literature data on the natural history and surgical management of ICH. EVIDENCE ACQUISITION A systematic review was performed using the PubMed and Embase databases, encompassing English, full-text articles, reporting treatment outcomes for the conservative and surgical management of ICH. EVIDENCE SYNTHESIS A total of 91 studies met the eligibility criteria (total of 16,411 ICH cases). The most common locations for an ICH were the basal ganglia for both the conservative (68.7%) and surgical cohorts (58.4%). Patients in the non-operative group (40.5%) were older (mean age 62.9 years; range 12.0-94.0), had a higher Glasgow Coma Scale (GCS) score at presentation (mean GCS 10.2; range 3-15) and lower ICH volume (mean 36.9 mL). When managed non-operatively, a favorable functional outcome was encountered in 25.7% (95% CI 16.9-34.5) of patients, with a 22.2% (95% CI 16.6-27.8) mortality rate. Patients who underwent surgery (59.5%) were younger (mean age 58.8 years; range 12.0-94.0), had a lower GCS at presentation (mean GCS 8.2; range 3-15) and larger ICH volume (mean 58.3 mL; range 8.2-140.0). Craniotomy with hematoma evacuation was the preferred surgical technique (38.6%). A favorable functional outcome was encountered in 29.8% (95% CI 23.8-35.8) of operated patients, with a 21.3% (95% CI 16.3-26.3) mortality rate. CONCLUSIONS For many ICH cases, the reviewed literature allows to define surgical and conservative candidates. However, there are still some ICH-cases where management remains controversial.

Abstract
OBJECTIVE This study aims to investigate the effect of minimal invasive microsurgery in treating primary hypertensive brainstem hemorrhage (PHBH). METHODS 52 patients of PHBH (≥3.5 ml) who have taken the minimal invasive microsurgery with neuronavigation guidance were included between Jan. 2011 and Dec. 2018. The volume/location/type of hematoma, preoperative Glasgow Coma Scale (GCS), postoperative Glasgow Outcome Scale (GOS) and hemorrhagic dilatation of the fourth ventricle were analyzed during the follow-up period ranged from 3 to 57 months. RESULTS Among all the patients, 18 achieved complete hematoma evacuation (≥95%), 31 achieved subtotal evacuation (≥90%), 3 achieved premodinantly evacuation (>75%). No rebleeding during or after surgery within 24 h were found. 45 patients survived after 3 months, the mean preoperative hematoma volume decreased from 7.1 ± 2.6 ml-0.9 ml (p < 0.05), 19 patients got GOS Grade V/Ⅳ. It is shown the volume less than 10 ml always led to better outcome while massive and bilateral hematoma were related with poor prognosis. CONCLUSION The microsurgical hematoma evacuation under neuronavigation assistance is a rapid, effective, and safe technique for the removal of PHBH, especially for the volume less than 10 ml.

Abstract
AbstractIntracerebral hemorrhage (ICH) accounts for 10% to 20% of strokes worldwide and is associated with high morbidity and mortality rates. Neuroimaging is indispensable for rapid diagnosis of ICH and identification of the underlying etiology, thus facilitating triage and appropriate treatment of patients. The most common neuroimaging modalities include noncontrast computed tomography (CT), CT angiography (CTA), digital subtraction angiography, and magnetic resonance imaging (MRI). The strengths and disadvantages of each modality will be reviewed. Novel technologies such as dual-energy CT/CTA, rapid MRI techniques, near-infrared spectroscopy, and automated ICH detection hold promise for faster pre- and in-hospital ICH diagnosis that may impact patient management.

Abstract
Rehabilitation therapy combined with nursing intervention in postoperative recovery of patients with hypertensive intracerebral hemorrhage was investigated. Retrospective analysis was carried out in 78 patients with severe HICH hematoma evacuation after treatment in Xuzhou No. 1 People's Hospital, Xuzhou Municipal Hospital Affiliated to Xuzhou Medical University from March 2014 to July 2017. The 28 patients who received routine treatment and nursing care were regarded as the control group, the 27 patients who underwent rehabilitation training based with routine treatment and nursing care were the rehabilitation training group. Moreover, the 23 patients who underwent rehabilitation training and nursing intervention based on routine treatment were regarded as the nursing intervention group. Systolic blood pressure, diastolic blood pressure, and Fugl-Meyer scores were compared immediately after surgery (T1), 4 weeks after treatment (T2) and 12 weeks after treatment (T3). During the period of T3, the total effective rate and adverse reactions were compared among the three groups of patients. The systolic blood pressure and diastolic blood pressure at T3 among the three groups were significantly lower than both T2 and T1, and the systolic and diastolic blood pressure of T2 was lower than T1 (P<0.05). Among the three groups of patients, the Fugl-Meyer score at T3 was significantly higher than both the T2 and T1, and the Fugl-Meyer score at T2 was higher than T1 (P<0.050). In the control group, the number of patients with shoulder-hand syndrome, hemorrhoids, and depression was significantly higher than both the rehabilitation training group and the nursing intervention group (P<0.050). The number of people with depression in the rehabilitation training group was significantly higher than the nursing intervention group (P<0.050). Rehabilitation therapy and nursing intervention are better than routine treatment and nursing for postoperative recovery of HICH patients, and has a lower adverse reaction rates after surgery, it is worthy of promotion clinically.

Abstract
Mitochondria autophagy, termed as mitophagy, is a mechanism of specific autophagic elimination of mitochondria. Mitophagy controls the quality and the number of mitochondria, eliminating dysfunctional or excessive mitochondria that can generate reactive oxygen species (ROS) and cause cell death. Mitochondria are centrally implicated in neuron and tissue injury after stroke, due to the function of supplying adenosine triphosphate (ATP) to the tissue, regulating oxidative metabolism during the pathologic process, and contribution to apoptotic cell death after stroke. As a catabolic mechanism, mitophagy links numbers of a complex network of mitochondria, and affects mitochondrial dynamic process, fusion and fission, reducing mitochondrial production of ROS, mediated by the mitochondrial permeability transition pore (MPTP). The precise nature of mitophagy’s involvement in stroke, and its underlying molecular mechanisms, have yet to be fully clarified. This review aims to provide a comprehensive overview of the integration of mitochondria with mitophagy, also to introduce and discuss recent advances in the understanding of the potential role, and possible signaling pathway, of mitophagy in the pathological processes of both hemorrhagic and ischemic stroke. The author also provides evidence to explain the dual role of mitophagy in stroke.

Abstract
Purpose—
Symptomatic intracranial hemorrhage (sICH) is the most feared complication of intravenous thrombolytic therapy in acute ischemic stroke. Treatment of sICH is based on expert opinion and small case series, with the efficacy of such treatments not well established. This document aims to provide an overview of sICH with a focus on pathophysiology and treatment.
Methods—
A literature review was performed for randomized trials, prospective and retrospective studies, opinion papers, case series, and case reports on the definitions, epidemiology, risk factors, pathophysiology, treatment, and outcome of sICH. The document sections were divided among writing group members who performed the literature review, summarized the literature, and provided suggestions on the diagnosis and treatment of patients with sICH caused by systemic thrombolysis with alteplase. Several drafts were circulated among writing group members until a consensus was achieved.
Results—
sICH is an uncommon but severe complication of systemic thrombolysis in acute ischemic stroke. Prompt diagnosis and early correction of the coagulopathy after alteplase have remained the mainstay of treatment. Further research is required to establish treatments aimed at maintaining integrity of the blood-brain barrier in acute ischemic stroke based on inhibition of the underlying biochemical processes.

Abstract
Background
To compare the in-hospital mortality and institutional morbidity from medical therapy (MT), external ventricular drainage (EVD) and suboccipital decompressive craniectomy (SDC) following an acute hemorrhagic posterior cranial fossa stroke (PCFH) in patients admitted to the neurosciences critical care unit (NCCU). Retrospective observational single-center cohort study in a tertiary care center. All consecutive patients (n = 104) admitted with PCFH from January 1st 2005–December 31st 2011 were included in the study. Methods
All patients with a PCFH were identified and confirmed by reviewing computed tomography of the brain reported by a specialist neuroradiologist. Management decisions (MT, EVD, and SDC) were identified from operative notes and electronic patient records. Results Following a PCFH, 47.8 % (n = 11) patients died after EVD placement without decompression, 45.7 % (n = 16) died following MT alone, and 17.4 % (n = 8) died following SDC. SDC was associated with lower mortality compared to MT with or without EVD (χ2 test p = 0.006, p = 0.008). Age, ICNARC score, brain stem involvement, and hematoma volume did not differ significantly between the groups. There was a statistically significant increase in hydrocephalus and intraventricular bleeds in patients treated with EVD placement and SDC (χ2 test p = 0.02). Median admission Glasgow Coma Scale scores for the MT only, MT with EVD, and SDC groups were 8, 6, and 7, respectively (ranges 3–15, 3–11 and 3–13) and did not differ significantly (Friedman test: p = 0.89). SDC resulted in a longer NCCU stay (mean of 17.4 days, standard deviation = 15.4, p < 0.001) and increased incidence of tracheostomy (50 vs. 17.2 %, p = 0.0004) compared to MT with or without EVD. Conclusions SDC following PCFH was associated with a reduction in mortality compared to expectant MT with or without EVD insertion. A high-quality multicenter randomized control trial is required to evaluate the superiority of SDC for PCFH.

Abstract
Hematoma lysis with recombinant tissue plasminogen activator (rtPA) has emerged as an alternative therapy for spontaneous intracerebral hemorrhage (ICH). Optimal dose and schedule are still unclear. The aim of this study was to create a reliable in vitro blood clot model for investigation of optimal drug dose and timing. An in vitro clot model was established, using 25 mL and 50 mL of human blood. Catheters were placed into the clots and three groups, using intraclot application of rtPA, placebo, and catheter alone, were analyzed. Dose-response relationship, repetition, and duration of rtPA treatment and its effectiveness in aged clots were investigated. A significant relative end weight difference was found in rtPA treated clots compared to catheter alone (p = 0.002) and placebo treated clots (p < 0.001). Dose-response analysis revealed 95% effective dose around 1 mg rtPA in 25 and 50 mL clots. Approximately 80% of relative clot lysis could be achieved after 15 min incubation. Lysis of aged clots was less effective. A new clot model for in vitro investigation was established. Our data suggest that current protocols for rtPA based ICH therapy may be optimized by using less rtPA at shorter incubation times.

Abstract
Intracerebral hemorrhage (ICH) is the second most common subtype of stroke and a critical disease usually leading to severe disability or death. ICH is more common in Asians, advanced age, male sex, and low- and middle-income countries. The case fatality rate of ICH is high (40% at 1 month and 54% at 1 year), and only 12% to 39% of survivors can achieve long-term functional independence. Risk factors of ICH are hypertension, current smoking, excessive alcohol consumption, hypocholesterolemia, and drugs. Old age, male sex, Asian ethnicity, chronic kidney disease, cerebral amyloid angiopathy (CAA), and cerebral microbleeds (CMBs) increase the risk of ICH. Clinical presentation varies according to the size and location of hematoma, and intraventricular extension of hemorrhage. Patients with CAA-related ICH frequently have concomitant cognitive impairment. Anticoagulation related ICH is increasing recently as the elderly population who have atrial fibrillation is increasing. As non-vitamin K antagonist oral anticoagulants (NOACs) are currently replacing warfarin, management of NOAC-associated ICH has become an emerging issue.

Abstract
Spontaneous non-traumatic intracerebral hemorrhage (ICH) remains a significant cause of mortality and morbidity throughout the world. To improve the devastating course of ICH, various clinical trials for medical and surgical interventions have been conducted in the last 10 years. Recent large-scale clinical trials have reported that early intensive blood pressure reduction can be a safe and feasible strategy for ICH, and have suggested a safe target range for systolic blood pressure. While new medical therapies associated with warfarin and non-vitamin K antagonist oral anticoagulants have been developed to treat ICH, recent trials have not been able to demonstrate the overall beneficial effects of surgical intervention on mortality and functional outcomes. However, some patients with ICH may benefit from surgical management in specific clinical contexts and/or at specific times. Furthermore, clinical trials for minimally invasive surgical evacuation methods are ongoing and may provide positive evidence. Upon understanding the current guidelines for the management of ICH, clinicians can administer appropriate treatment and attempt to improve the clinical outcome of ICH. The purpose of this review is to help in the decision-making of the medical and surgical management of ICH.

Abstract
Intracerebral hemorrhage (ICH) is a very complex pathology, with many different not fully elucidated etiologies and prognostics. It is the most severe subtype of stroke, with high mortality and morbidity rates. Unfortunately, despite the numerous promising preclinical assays including neuroprotective, anti-hypertensive, and anti-inflammatory drugs, to this moment only symptomatic treatments are available, motivating the search for new alternatives. In this context, stem cell therapy emerged as a promising tool. However, more than a decade has passed, and there is still much to be learned not only about stem cells, but also about ICH itself, and how these two pieces come together. To date, rats have been the most widely used animal model in this research field, and there is much more to be learned from and about them. In this review, we first summarize ICH epidemiology, risk factors, and pathophysiology. We then present different methods utilized to induce ICH in rats, and examine how accurately they represent the human disease. Next, we discuss the different types of stem cells used in previous ICH studies, also taking into account the tested transplantation sites. Finally, we summarize what has been achieved in assays with stem cells in rat models of ICH, and point out some relevant issues where attention must be given in future efforts.

Abstract
Background: Hypertension damages small vessels, resulting in both lacunar infarction and subcortical intracerebral hemorrhage (ICH). Substance abuse has also been linked to small vessel pathology. This study explores whether the use of specific substances (e.g., cocaine, tobacco) is associated with subcortical ICH over ischemia in hypertensive individuals. Methods: Patients with hypertension, admitted with lacunar infarcts (measuring <2.0 cm) or subcortical ICH, were included in analysis. Brain MRIs and head CTs were retrospectively reviewed along with medical records. Demographic information and history of substance use (illicit/controlled: cocaine, heroin, marijuana, benzodiazepines, and methadone; alcohol; and tobacco) was obtained. “Current use” and “history of use” were determined from patient history or a positive toxicology screen. “Heavy use” was defined as: smoking- ≥0.5 packs per day or 10 pack-years; alcohol- average of >1 drink per day (women), >2 drinks per day (men). Logistic regression was performed with ICH as the dependent variable comparing those presenting with ICH to those presenting with ischemia. Results: Of the 580 patients included in analysis, 217 (37%) presented with ICH. The average age was similar between the two groups (64.7 versus 66.3 years). Illicit/controlled drug use was associated with a significantly increased risk of ICH over stroke in unadjusted models (25 versus 15%, p = 0.02), with the largest effect seen in users ≥65 years old (not statistically significant). Smoking was associated with ischemia over ICH in a dose-dependent manner: any history of smoking OR 1.84, CI 1.19–2.84; current use OR 2.23, CI 1.37–3.62; heavy use OR 2.48, CI 1.50–4.13. Alcohol use was not preferentially associated with either outcome (p = 0.29). Conclusion: In hypertensive patients, tobacco use is associated with an increased risk of subcortical ischemia compared to ICH, while use of illicit/controlled substances appears to be predictive of hemorrhage.

Abstract
OBJECTIVE To compare two different methods for measuring intracerebral hemorrhage (ICH) volume: the ellipse volume (called ABC/2), and the software-aided planimetric. METHODS Four observers evaluated 20 brain computed tomography (CT) scans with spontaneous ICH. Each professional measured the volume using the ABC/2 and the planimetric methods. The average volumes were obtained, and the intra- and inter-rater variability was determined. RESULTS There is an absolute 2.24 cm3 average difference between both methodologies. Volumes yielded by the ABC/2 method were as much as 14.9% smaller than by the planimetric one. An intra-observer variability rate of 0.46% was found for the planimetric method and 0.18% for the ABC/2. The inter-observer rates were 1.69 and 1.11% respectively. CONCLUSIONS Both methods are reproducible. The ABC/2 yielded hemorrhage volumes as much as 14.9% smaller than those measured using the planimetric methodology.

Abstract
Intracerebral hemorrhage (ICH) is a significant cause of morbidity and mortality. With the aging population, increased use of anticoagulants, and changing racial and ethnic landscape of the United States, the incidence of ICH will increase over the next decade. Improvements in preventative strategies to treat hypertension and atrial fibrillation are necessary to change the trajectory of this increase. Advances in the understanding of ICH at the vascular and molecular level may pave the way to new treatment options. This article discusses the epidemiology, pathophysiology, and current treatment options for patients with ICH. Differences in outcome and treatment between patients taking and not taking anticoagulant therapies are considered.

Abstract
Elevated intracranial pressure can be caused by a variety of underlying conditions. Several physiologic and pharmacologic factors have a significant impact on intracranial hypertension, mostly caused by changes on cerebral blood volume, flow, and oxygenation. There are many therapies that can be used to decrease intracranial pressure ranging from pharmacologic to the surgical decompressive removal of the calvarium. Special consideration is made for the anesthetic management of these patients perioperatively.

Abstract
PURPOSE OF REVIEW This article provides an update on the latest diagnostic and therapeutic trials relating to the management of intracerebral hemorrhage (ICH). RECENT FINDINGS Early hematoma expansion and worsening cerebral edema may account for delayed neurologic deterioration after ICH. SUMMARY Despite advances in other areas of stroke, there has been no significant improvement in the morbidity and mortality after ICH. The cause of ICH has been shifting from chronic hypertension to other etiologies. Current understanding of the pathophysiologic processes involved with hematoma expansion and the development of secondary injury after ICH has focused the treatment strategies on prevention of these potential complications. Care for the patient after ICH includes basic medical care, prevention of hematoma expansion, and treatment of potential secondary complications. Trials are underway to evaluate the effect of acute blood pressure control on hematoma expansion and the development of cerebral edema. Similarly, new surgical techniques are being explored for clot removal, and medical therapies are being developed to prevent secondary neurotoxic damage.

Abstract
Hematoma puncture and subsequent clot lysis with recombinant tissue plasminogen activator (rtPA) emerged as an alternative therapy for spontaneous intracerebral hemorrhage (ICH) and is associated with delayed edema possibly counteracting the beneficial effects of hematoma volume reduction. We hypothesized that immediate reversal of rtPA activity after clot lysis and hematoma drainage diminishes edema formation. To test this hypothesis, we administered plasminogen activator inhibitor (PAI)-1 after rtPA lysis of experimentally induced ICH. A right frontal ICH was placed through a twist drill burr hole and autologous blood injection. Following creation of the frontal ICH, pigs received no further treatment (n = 5), lysis with rtPA (n = 7), or lysis with rtPA followed by administration of PAI-1 (n = 6). Hematoma and edema volumes were assessed with magnetic resonance imaging on days 0, 4, and 10. The rtPA significantly reduced hematoma volume and contributed to edema on day 10 after experimentally induced ICH. Administration of PAI-1 attenuated the rtPA-induced edema volume on day 10, but the hematoma volume reduction was less pronounced. In conclusion, PAI-1 attenuated delayed cerebral edema after rtPA lysis of experimental ICH but also reduced the lytic activity of rtPA. The combination of rtPA clot lysis with PAI-1 might have the potential to further improve the effect of the lytic therapy of ICH, but additional studies to define the optimum time point for PAI-1 administration are required.

[PMID: 22484068 DOI: 10.1016/j.wneu.2012.03.026] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2011] [Revised: 02/18/2012] [Accepted: 03/30/2012] [Indexed: 11/22/2022]
Abstract
BACKGROUND The aim of this study was to determine and compare 30-day mortalities and 90-day functional recoveries after first and recurrent primary intracerebral hemorrhage (PICH) attacks. The investigators sought to identify factors predisposing 30-day mortality and functional recovery and to compare patients after first and recurrent PICH attacks. METHODS The medical records of 1856 PICH patients treated in Samsung Changwon Hospital and Dong-A University Medical Center from January 2000 to December 2010 were retrospectively evaluated. RESULTS Of these 1856 patients, 1499 were included. Mean patient age was 66.4 ± 16.3 years, and there were 742 male patients (49.5%). Recurrent PICH occurred in 142 (9.5%) patients. Thirty-day mortality was 13.6% for first PICH patients and 14.1% for recurrent PICH patients (P = 0.824). Good functional recovery at 90 days after ictus was achieved by 52.2% of first PICH patients and by 31.0% of recurrent patients (P = 0.003). In both groups, multivariate analysis showed that unconsciousness, pupillary abnormality, surgery, and underlying disease were associated with high mortality, and that consciousness, a lobal location, a small hemorrhagic volume, and conservative treatment were associated with good functional recovery. After excluding recurrent patients with a previous moderate to severe disability due to the sequelae of PICH, no difference was found between the first (25.1%) and recurrent groups (19.0%) in terms of functional recovery (P = 0.083). CONCLUSIONS The factors found to predispose clinical outcome were similar in the two groups. This study shows that given optimal treatment, recurrent PICH patients can achieve the same clinical outcomes as first PICH patients.

Abstract
Intracerebral hemorrhage (ICH) is a neurologic emergency associated with regular, early, ongoing hemorrhage, progressive clinical deterioration, severe deficits, and high mortality. Hence, it requires prompt recognition, diagnosis, and management. Initial monitoring and management of patients with ICH should occur in an intensive care unit. The overall approach to treatment mandates using therapies to stop or slow the initial bleeding acutely, removing blood from the parenchyma or ventricles (in eligible patients) to prevent secondary brain injury, addressing raised intracranial pressure, and providing good, comprehensive supportive care, including management of airways, oxygenation, blood pressure, circulation, glucose level, fever, and nutrition, as well as deep venous thrombosis prophylaxis.

Abstract
The factors related to death and functional recovery after primary pontine hemorrhage (PPH) in Koreans has not been well defined. The authors sought to identify independent predictors of death and functional recovery after PPH using data obtained at a single institute. Data were collected retrospectively on 281 patients with PPH admitted to the Stroke Unit at our hospital between January 1, 2000 and December 31, 2009. Multivariate logistic regression analysis was used to evaluate the associations between selected variables and 30-day mortality and 90-day functional recovery after PPH. One-hundred and ten patients (39.1%) died within 30 days of PPH and 27 patients (9.6%) achieved functional recovery within 90 days. By multivariate analysis, unconsciousness, dilated pupils, abnormal respiration, systolic blood pressure < 100 mmHg, hydrocephalus, and conservative treatment were found to be predictors of 30-day mortality, whereas consciousness, intact motor function, no history of hypertension or diabetes mellitus, intact eye movement, a hematoma volume of < 5 mL, no ventricular hemorrhage, and normally sized ventricle were found to be predictors of 90-day functional recovery. The present findings suggest that systolic hypotension of less than 100 mmHg may predict 30-day mortality and a history of underlying hypertension and diabetes mellitus may predict 90-day functional recovery.

Abstract
BACKGROUND AND PURPOSE Recombinant Factor VIIa decreases hematoma growth after spontaneous intracerebral hemorrhage (ICH) and rapidly decreases international normalized ratios in patients on warfarin but is also associated with an increased risk for thromboembolic complications. In this study, we assessed the risk of thromboembolic events in patients receiving recombinant Factor VIIa after ICH associated with warfarin treatment. METHODS We reviewed the medical charts, laboratory data, and radiological findings of consecutive patients with anticoagulation-related hemorrhages of the central nervous system who received recombinant Factor VIIa at Mayo Clinic Rochester and Mayo Clinic Florida between 2002 and 2009. The primary end point was the frequency of new thromboembolic events, including myocardial infarction, deep vein thrombosis, ischemic stroke, and pulmonary embolism. RESULTS We identified 101 patients; 54% had ICH and 30% subdural hematomas. The most common indications for anticoagulation were atrial fibrillation, deep vein thrombosis, and prosthetic valve. Thirteen patients (12.8%) had new thromboembolic events (10 deep vein thromboses and 3 ischemic strokes) within 90 days after recombinant Factor VIIa administration. Eight of these adverse events occurred within 2 weeks of treatment. In patients with ICH, the rate of thromboembolic complications was 5% and all events were venous. CONCLUSIONS The risk of thromboembolic events in patients who received recombinant Factor VIIa for anticoagulation-associated ICH was not higher than that seen in patients treated for spontaneous ICH in the Factor Seven for Acute Hemorrhagic Stroke (FAST) trial. Spontaneous deep vein thrombosis was the most common complication in our series.

Abstract
BACKGROUND AND PURPOSE Risk-stratification models based on patient and disease characteristics are useful for aiding clinical decisions and for comparing the quality of care between different physicians or hospitals. In addition, prediction of mortality is beneficial for optimizing resource utilization. We evaluated the accuracy and discriminating power of the random forest (RF) to predict 30-day mortality of spontaneous intracerebral hemorrhage (SICH). METHODS We retrospectively studied 423 patients admitted to the Taichung Veterans General Hospital who were diagnosed with spontaneous SICH within 24 h of stroke onset. The initial evaluation data of the patients were used to train the RF model. Areas under the receiver operating characteristic curves (AUC) were used to quantify the predictive performance. The performance of the RF model was compared to that of an artificial neural network (ANN), support vector machine (SVM), logistic regression model, and the ICH score. RESULTS The RF had an overall accuracy of 78.5% for predicting the mortality of patients with SICH. The sensitivity was 79.0%, and the specificity was 78.4%. The AUCs were as follows: RF, 0.87 (0.84-0.90); ANN, 0.81 (0.77-0.85); SVM, 0.79 (0.75-0.83); logistic regression, 0.78 (0.74-0.82); and ICH score, 0.72 (0.68-0.76). The discriminatory power of RF was superior to that of the other prediction models. CONCLUSIONS The RF provided the best predictive performance amongst all of the tested models. We believe that the RF is a suitable tool for clinicians to use in predicting the 30-day mortality of patients after SICH.

Abstract
OBJECTIVE The aim of this study was to develop a grading scale for predicting the 30-day mortality of spontaneous intracerebral hemorrhage (ICH) using initial evaluation data. DESIGN Univariate and multivariate logistic regression models were used to identify independent risk factors and to construct a grading scale for predicting the outcome of ICH. SETTING The Taichung Veterans General Hospital in Taichung, Taiwan. PARTICIPANTS Two hundred and ninety-three patients were diagnosed with spontaneous ICH between 1 January 2006 and 31 December 2007. INTERVENTION Development of the simplified ICH score (sICH score) for predicting the 30-day mortality of ICH. MAIN OUTCOME MEASURES The discrimination of the prediction model was determined by measuring the accuracy, sensitivity, specificity and the area under the receiver operating characteristic curves (AUC). RESULTS The accuracy of the sICH score was 80.5%, the sensitivity was 82.5% and the specificity was 80.2%. The AUCs are as follows: sICH score, 0.89 (0.84-0.94); ICH score, 0.74 (0.65-0.83) and ICH-GS, 0.74 (0.65-0.83). CONCLUSIONS The sICH score showed best discrimination among tested models. Also, it was easier for physicians without special training in neurology or radiology to use this scale. With statistical power and ease of use, the sICH score is a very suitable model for risk stratification of spontaneous ICH.

Abstract
OBJECTIVE The purpose of this study was to identify independent predictors of mortality and functional recovery in patients with primary intracerebral hemorrhage (PICH) and to improve functional outcome in these patients. METHODS Data were collected retrospectively on 585 patients with supratentorial PICH admitted to the Stroke Unit at our hospital between 1st January 2004 and the 31st July 2008. Using multivariate logistic regression analysis, the associations between all selected variables and 30-day mortality and 90-day functional recoveries after PICH was evaluated. RESULTS Ninety-day functional recovery was achieved in 29.1% of the 585 patients and 30-day mortality in 15.9%. Age (OR=7.384, p=0.000), limb weakness (OR=6.927, p=0.000), and hematoma volume (OR=5.293, p=0.000) were found to be powerful predictors of 90-day functional recovery. Furthermore, initial consciousness (OR=3.013, p=0.014) hematoma location (lobar, OR=2.653, p=0.003), ventricular extension of blood (OR=2.077, p=0.013), leukocytosis (OR=2.048, p=0.008), alcohol intake (drinker, OR=1.927, p=0.023), and increased serum aminotransferase (OR=1.892, p=0.035) were found to be independent predictors of 90-day functional recovery after PICH. On the other hand, a pupillary abnormality (OR=4.532, p=0.000) and initial unconsciousness (OR=3.362, p=0.000) were found to be independent predictors of 30-day mortality after PICH. CONCLUSION The predictors of mortality and functional recovery after PICH identified during this analysis may assist during clinical decision-making, when advising patients or family members about the prognosis of PICH and when planning intervention trials.
