J Ultrasound 2024:10.1007/s40477-024-00943-3. [PMID: 39102104 DOI: 10.1007/s40477-024-00943-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 06/30/2024] [Indexed: 08/06/2024] Open
Abstract
Intracerebral hemorrhage (ICH) is a common neurosurgical emergency that is associated with high morbidity and mortality. Minimally invasive or endoscopic hematoma evacuation has emerged in recent years as a viable alternative to conventional large craniotomies. However, accurate trajectory planning and placement of the tubular retractor remains a challenge. We describe a novel technique for handheld portable ultrasound-guided minimally invasive endoscopic evacuation of supratentorial hematomas. A 64-year-old male diagnosed right hematoma (48.5 mL) at the basal ganglia was treated with emergent ultrasound-guided endoscopic transtubular evacuation through a small craniotomy. Ultrasound-guidance facilitated optimal placement of the tubular retractor into the long axis of the hematoma, and allowed for near-total evacuation, reducing iatrogenic tissue damage by mitigating the need for wanding or repositioning of the retractor. The emergence of a new generation of small portable phased array ultrasound probes with improved resolution and clarity has broadened ultrasound's clinical applications.

Abstract
Stroke is a medical condition that results from a decreased or completely diminished supply of blood to the brain, and it is considered one of the major causes of morbidity and mortality globally. Stroke is categorized as ischemic and hemorrhagic stroke, both of which demand prompt and particular timely intervention. This extensive review is done to investigate the precise management of acute and chronic manifestations of stroke in relation to neurosurgical interventions, ultimately providing a thorough analysis regarding indications, procedures, outcomes, and complications that are associated with it. In this regard, a pervasive review of literature was carried out, which was primarily sourced from literature databases such as PubMed. This paper particularly outlines a sound relative analysis of anticipating the competence of each neurosurgical technique in use. Endovascular clot retrieval (ECR) has been particularly highlighted, as its effectiveness has been profoundly observed when selected as a treatment option within a time period of 6-24 hours following an ischemic stroke. In less than a time frame of 48 hours, decompressive hemicraniectomy (DH) is usually considered the most suitable treatment for cases of intracranial hypertension resulting from middle cerebral artery (MCA) infarction. Hemorrhages that occur due to ruptured aneurysms are most commonly dealt with clipping and neuroendovascular techniques. Additionally, considering that revascularization surgery is time-sensitive, the results can ultimately vary. Competent results have been linked with stereotactic surgery, which includes deep brain stimulation (DBS) and focused ultrasound ablation (FUSA), which are also famous for being minimally invasive in nature. However, the broader application of these techniques is hindered by the absence of established protocols. This review highlights the importance of timely interventions, advanced equipment, and precise medical protocols to optimize treatment outcomes.

Application of Robotic Stereotactic Assistance (ROSA) for spontaneous intracerebral hematoma aspiration and thrombolytic catheter placement. J Formos Med Assoc 2024:S0929-6646(24)00254-7. [PMID: 38866694 DOI: 10.1016/j.jfma.2024.05.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 05/22/2024] [Accepted: 05/27/2024] [Indexed: 06/14/2024] Open
Abstract
BACKGROUND Spontaneous intracerebral hemorrhage (ICH) accounts for up to 20% of all strokes and results in 40% mortality at 30 days. Although conservative medical management is still the standard treatment for ICH patients with small hematoma, patients with residual hematoma ≤15 mL after surgery are associated with better functional outcomes and survival rates. This study reported our clinical experience with using Robotic Stereotactic Assistance (ROSA) as a safe and effective approach for stereotactic ICH aspiration and intra-clot catheter placement. METHODS A retrospective analysis was conducted of patients with spontaneous ICH who underwent ROSA-guided ICH aspiration surgery. ROSA-guided ICH surgical techniques, an aspiration and intra-clot catheter placement protocol, and a specific operative workflow (pre-operative protocol, intraoperative procedure and postoperative management) were employed to aspirate ICH using the ROSA One Brain, and appropriate follow-up care was provided. RESULTS From September 14, 2021 to May 4, 2022, a total of 7 patients were included in the study. Based on our workflow design, ROSA-guided stereotactic ICH aspiration effectively aspirated more than 50% of hematoma volume (or more than 30 mL for massive hematomas), thereby reducing the residual hematoma to less than 15 mL. The mean operative time of entire surgical procedure was 1.3 ± 0.3 h, with very little perioperative blood loss and no perioperative complications. No patients required catheter replacement and all patients' functional status improved. CONCLUSIONS Within our clinical practice ROSA-guided ICH aspiration, using our established protocol and workflow, was safe and effective for reducing hematoma volume, with positive functional outcomes.

Comparison of the Efficacy of Subosseous Window Neuro-Endoscopy and Minimally Invasive Craniotomy in the Treatment of Basal Ganglia Hypertensive Intracerebral Hemorrhage. J Craniofac Surg 2023; 34:e724-e728. [PMID: 37271862 PMCID: PMC10597438 DOI: 10.1097/scs.0000000000009461] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Accepted: 04/17/2023] [Indexed: 06/06/2023] Open
Abstract
OBJECTIVE To compare the perioperative indexes and long-term effects of craniotomy and neuro-endoscopic hematoma removal in patients with hypertensive intracerebral hemorrhage (HICH) in the basal ganglia region. METHODS This study involved 128 patients with HICH in the basal ganglia region who were admitted to our hospital from February 2020 to June 2022. They were divided into 2 groups according to the random number table method. The craniotomy group (n = 70) underwent microsurgery with small bone window craniotomy with a side cleft, and the neuro-endoscopy group (n = 58) underwent small bone window neuro-endoscopic surgery. A 3-dimensional Slicer was used to calculate the hematoma volume and clearance rate and the postoperative brain tissue edema volume. The operation time, intraoperative blood loss, postoperative intracranial pressure, complications, mortality, and improvement in the modified Rankin scale score at 6 months postoperatively were compared between the two groups. RESULTS The clearance rate was significantly higher in the neuro-endoscopy group than in the craniotomy group (94.16% ± 1.86% versus 90.87% ± 1.89%, P < 0.0001). The operation time was significantly lower in the neuro-endoscopy group than in the craniotomy group (89.9 ± 11.7 versus 203.7 ± 57.6 min, P < 0.0001). Intraoperative blood loss was significantly higher in the craniotomy group (248.31 ± 94.65 versus 78.66 ± 28.96 mL, P < 0.0001). The postoperative length of stay in the intensive care unit was 12.6 days in the neuro-endoscopy group and 14.0 days in the craniotomy group with no significant difference ( P = 0.196). Intracranial pressure monitoring showed no significant difference between the two groups on postoperative days 1 and 7. Intracranial pressure was significantly higher in the craniotomy group than in the neuro-endoscopy group on postoperative day 3 (15.1 ± 6.8 versus 12.5 ± 6.8 mm Hg, P = 0.029). There was no significant difference in the mortality or outcome rate at 6 months postoperatively between the two groups. CONCLUSIONS In patients with HICH in the basal ganglia region, neuro-endoscopy can significantly improve the hematoma clearance rate, reduce intraoperative hemorrhage and postoperative cerebral tissue edema, and improve surgical efficiency. However, the long-term prognosis of patients who undergo craniotomy through the lateral fissure is similar to that of patients who undergo neuro-endoscopic surgery.

Abstract
BACKGROUND Minimally invasive surgery is effective and recommended for treatment of intracerebral hemorrhage; however, neurosurgeons in grass-root hospitals in underdeveloped countries lack effective and precise minimally invasive surgery techniques. The aim of this study was to present a technique of computed tomography angiography-based three-dimensional-printed navigation mold-guided stereotactic aspiration and demonstrate its clinical application using a hard needle in a series of patients. METHODS The novel stereotactic aspiration technique was performed in 18 patients with spontaneous intracerebral hemorrhage at our center, and clinical outcomes were reported. We compared the volume of hematoma measured by 3 different methods: ABC/2 formula, manual segmentation with OsiriX, and manual segmentation with 3D Slicer. RESULTS The surgery was completed safely within an average operative time of 15.11 minutes, achieving the goal of <15 mL residual clot volume or >70% clot removal in all patients. No intracranial rebleeding or infection was observed postoperatively. At the end of the 6-month follow-up, 61.11% (11/18) of patients achieved a modified Rankin Scale score <3. There was overall better agreement of hematoma measurement using segmentation with 3D Slicer rather than ABC/2 measurement or hematoma measurement using segmentation with OsiriX. CONCLUSIONS Our novel method of stereotactic aspiration benefited patients in this study with good percent clot removal, few surgery-related complications, and a favorable prognosis. Manual segmentation with 3D Slicer could be used to provide the neurosurgeon with dependable information about hematoma volume. This cheap and convenient technique may be applied in grass-root hospitals in underdeveloped countries. Assessment in multicenter prospective clinical trials is needed.

Abstract
BACKGROUND AND IMPORTANCE Intraparenchymal hemorrhage (IPH) is a debilitating and highly morbid type of stroke with limited effective treatment modalities. Minimally invasive evacuation with tissue plasminogen activator (rt-PA) has demonstrated promise for mortality/functional improvements with adequate clot volume reduction. In this study, we report 2 cases of continuous rt-PA infusion using a closed circuit, dual lumen catheter, and irrigation system (IRRAflow) for IPH treatment. CLINICAL PRESENTATION A 55-year-old man was admitted for acute onset left hemiparesis; he was found to have right basal ganglia IPH. He was treated with continuous rt-PA irrigation using the IRRAflow device, at a rate of 30 mL/h for 119 hours, with a total volume reduction of 87.8 mL and post-treatment volume of 1.2 mL. At 3-month follow-up, he exhibited a modified Rankin score of 4 and improved hemiparesis. A 39-year-old woman was admitted for acute onset left facial droop, left hemianopsia, and left hemiparesis; she was diagnosed with a right basal ganglia IPH. She was treated with drainage and continuous rt-PA irrigation at 30 mL/h for 24 hours, with a total hematoma volume reduction of 41 mL and with a final post-treatment volume of 9.1 mL. At 3-month follow-up, she exhibited a modified Rankin score of 3 with some improvement in left hemiparesis. CONCLUSION Continuous rt-PA infusion using a minimally invasive catheter with saline irrigation was feasible and resulted in successful volume reduction in 2 patients with IPH. This technique is similar to the Minimally Invasive Surgery Plus rt-PA for Intracerebral Hemorrhage Evacuation (MISTIE) approach but offers the potential advantages of less breaks in the sterile circuit, continuous intracranial pressure monitoring, and may provide more efficient clot lysis compared with intermittent bolusing.

Abstract
Intracerebral hemorrhage (ICH) is a devastating form of stroke with high rates of morbidity, mortality, and disability. It induces cell death that is responsible for the secondary brain injury (SBI). The underlying mechanism of SBI after ICH is still unclear, and whether it is related to iron overload is worthy to be discussed. Ferroptosis is an iron-dependent non-apoptotic modes of cell death and plays a particularly important role in the occurrence and progression of ICH. Many ICH-induced regulators and signalling pathways of ferroptosis have been reported as promising targets for treating ICH. In this article, we review the definition, characteristics, and inhibition methods of neuronal ferroptosis caused by iron deposition after ICH, and review the biomarkers for ferroptosis.

Abstract
OBJECTIVE To compare outcomes in neuroendoscopic-assisted vs mini-open craniotomy for hypertensive intracerebral hemorrhage (HICH), so as to provide reasonable surgical treatment. METHODS Clinical data of 184 patients with HICH in the hospital from January 2019 to May 2021 were analyzed retrospectively. The patients were divided into mini-open craniotomy group and neuroendoscopic-assisted group. The operation time, hematoma clearance rate, intraoperative blood loss, neurological function recovery, and postoperative mortality of the two groups were compared by retrospective analysis. RESULTS The operation time and intraoperative blood loss in the mini-open craniotomy group were more than those in the neuroendoscopic-assisted group, but there was no significant difference between the two groups. There was no significant difference in hematoma clearance rate between the two groups, but for the rugby hematoma, the hematoma clearance rate in the neuroendoscopic-assisted group was higher than in the mini-open craniotomy group, the difference was statistically significant. Within 1 month after the operation, there was no significant difference in mortality between the two groups. 6 months after the operation, there was no significant difference in the recovery of neurological function between the two groups. CONCLUSION Neuroendoscopic-assisted and mini-open craniotomy for the treatment of HICH has the advantages of minimal trauma with good effects, and its main reason for short operation time, reduced bleeding, and high hematoma clearance rate. Although the two surgical methods can improve the survival rate of patients, they do not change the prognosis of patients. Therefore, the choice of surgical methods should be adopted based on the patient's clinical manifestations, hematoma volume, hematoma type, and the experience of the surgeon.

Abstract
Background and PurposeMinimally invasive surgery (MIS) is performed to treat patients with intracerebral hemorrhage (ICH) with favorable results. However, postoperative rehemorrhage is a significant risk. The present study retrospectively analyzed the association of irregular-shaped hematoma with postoperative rehemorrhage following stereotactic MIS (sMIS).MethodsWe enrolled 548 patients with spontaneous ICH who underwent sMIS. Based on the hematoma shape, the patients were assigned to the regular-shaped hematoma group (RSH group; 300 patients) or irregular-shaped hematoma group (ISH group; 248 patients). Logistic regression analysis was performed to identify the predictors of postoperative rehemorrhage after sMIS for ICH evacuation. The functional outcome was assessed using the modified ranking scale (mRS) score at discharge. A receiver operating characteristic (ROC) curve was used to confirm the results.ResultsAmong 548 patients with ICH who underwent sMIS, 116 developed postoperative rehemorrhage. Postoperative rehemorrhage occurred in 30.65% of patients with ISH and 13.30% with RSH (P < 0.01), with a significant difference between the ISH and RSH groups. Among 116 patients with postoperative rehemorrhage, 76 (65.52%) showed ISH on CT scan. In 432 patients without postoperative rehemorrhage, only 39.81% displayed ISH. The logistic regression analysis demonstrated that ISH could independently predict postoperative rehemorrhage. The sensitivity, specificity, positive predictive value, and negative predicative value were 0.655, 0.398, 0.655, and 0.602, respectively. The ROC analysis confirmed the value of ISH in predicting postoperative rehemorrhage with an area under the curve of 0.629.ConclusionsIrregular-shaped hematoma was an independent predictor of postoperative rehemorrhage after sMIS.

Abstract
Postoperative neurological disorders, including postoperative delirium (POD), postoperative cognitive dysfunction (POCD), postoperative covert ischemic stroke, and hemorrhagic stroke, are challenging clinical problems in the emerging aged surgical population. These disorders can deteriorate functional outcomes and long‐term quality of life after surgery, resulting in a substantial social and financial burden to the family and society. Understanding predisposing and precipitating factors may promote individualized preventive treatment for each disorder, as several risk factors are modifiable. Besides prevention, timely identification and treatment of etiologies and symptoms can contribute to better recovery from postoperative neurological disorders and lower risk of long‐term cognitive impairment, disability, and even death. Herein, we summarize the diagnosis, risk factors, prevention, and treatment of these postoperative complications, with emphasis on recent advances and perspectives.

Abstract
Objective The surgical method for treating spontaneous intracranial hemorrhage (ICH) is not well established despite ICH's high prevalence and poor prognosis. Minimally invasive surgery has recently received attention; however, literature on this method is scarce. In particular, the appropriate location of the catheter in the hematoma has not been described. We examined whether the catheter position affects the hematoma reduction in a hematoma >50 cc. Methods We investigated the prognoses of 36 patients with ICH who underwent stereotactic aspiration and hematoma drainage using urokinase from January 2010 to December 2018 and the hematoma reduction rates according to the tube position. Two methods evaluated the position of the catheter. In the first method, the hematoma was an imaginary sphere. The center point was set as the operation target. We evaluated the catheter position by determining whether it was in the deep part or the outer part of the half point from that location to the hematoma margin. In the second method, we evaluated whether the catheter was located 1 cm inside the hematoma margin. Results In both the first and second evaluations, there were no differences in age, midline shift, intraventricular hemorrhage status, hematoma volume on admission, Glasgow Coma Scale score on admission, time to operation after symptom onset, and systolic blood pressure. The rates of decrease in bleeding and the prognoses were also not significantly different. Conclusions If the catheter is in the hematoma, the rate of hematoma reduction at any position is similar.

Abstract
OBJECTIVE Tissue plasminogen activator (tPA) fibrinolysis did not improve functional outcomes of patients with intraventricular hemorrhage (IVH), largely because of the unsatisfactory clot clearance. The presence of neutrophil extracellular traps (NETs) within the clot has been confirmed to impair tPA fibrinolysis, but the mechanism has been unclear. The authors hypothesized that cell-free DNA (cfDNA), the main framework of NETs, might be the important reason for the fibrinolysis resistance, and they validated the hypothesis, hoping to provide a new target to promote intraventricular fibrinolysis. METHODS First, cfDNA was detected in IVH clots by immunofluorescence staining in a rat model of IVH. Second, after blood (with or without exogenous cfDNA) intraventricular injection, IVH rats were given intraventricular infusion of 2 μl of saline, tPA, or tPA + DNase1 randomly. Then, the ventricular volume, animal behavior, and reactive astrocyte proliferation were assessed. Third, the IVH clots were collected for fibrinolysis assay in vitro. Finally, the effects of exogenous cfDNA in IVH were evaluated. RESULTS The presence of cfDNA in clots was observed as early as 1 hour after IVH. Compared with the whole-blood model, blood + cfDNA caused more severe ventricular dilation (day 7: blood 32.47 ± 2.096 mm3 vs blood + DNA 40.09 ± 2.787 mm3, p < 0.05), increased fibrinolysis resistance to tPA (day 7: tPA + DNA 26.04 ± 1.318 mm3 vs tPA 22.15 ± 1.706 mm3, p < 0.05), and further deteriorated the functional defects in rats (blood vs blood + DNA, p < 0.05). Degradation of cfDNA by DNase1 further enhanced the fibrinolysis effects on relieving the ventricular dilation (day 7: tPA + DNase1 11.67 ± 2.023 mm3 vs tPA, p < 0.05), improving the functional outcome (tPA vs tPA + DNase1, p < 0.05) and reducing periventricular astrocyte proliferation. CONCLUSIONS cfDNA impaired tPA fibrinolysis for IVH, and degradation of cfDNA may be a new target to improve this condition.

Clinical and radiographic factors involved in achieving a hematoma evacuation rate of more than 70% through minimally invasive catheter drainage for spontaneous intracerebral hemorrhage. J Clin Neurosci 2021; 92:103-109. [PMID: 34509234 DOI: 10.1016/j.jocn.2021.07.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 07/23/2021] [Accepted: 07/24/2021] [Indexed: 11/29/2022]
Abstract
Although stereotactic or neuronavigation-guided hematoma drainage for spontaneous intracerebral hemorrhage (ICH) is widely used, its clinical efficacy and factors for predictive results remain to be fully elucidated. This study sought to determine the efficacy of hematoma evacuation for spontaneous ICH, in addition to the factors affecting it. We retrospectively reviewed patients who underwent stereotactic or neuronavigation-guided catheter insertion for spontaneous ICH at our institute between April 2010 and December 2019. We identified and compared the clinical and radiographic factors between groups according to the hematoma evacuation rate of 70%. Logistic regression analyses were performed to identify factors affecting hematoma evacuation. We investigated whether the hematoma evacuation rate was associated with patient survival. A total of 95 patients who underwent stereotactic or neuronavigation-guided catheter insertion and hematoma drainage for spontaneous ICH were included. A multivariate analysis indicated that a hematoma volume of 30-60 cm3 (odds ratio [OR] = 8.064, 95% confidence interval [CI] = 2.285-28.468, P = 0.001), blend sign (OR = 6.790, 95% CI = 1.239-37.210, P = 0.027), diabetes (OR = 0.188, 95% CI = 0.041-0.870, P = 0.032), and leukocytosis (OR = 3.061, 95% CI = 1.094-8.563, P = 0.033) were significantly associated with a higher hematoma evacuation. The mean hematoma evacuation rate in patients with 1-month mortality was lower than that in survivors (P = 0.051). Our study revealed that a hematoma volume of 30-60 cm3, the presence of a blend sign and leukocytosis, and the absence of diabetes are independent predictors that affect more than 70% of hematoma evacuations.

Abstract
INTRODUCTION The intracerebral hemorrhage (ICH) score provides an estimate of 30-day mortality for patients with intracerebral hemorrhage in order to guide research protocols and clinical decision making. Several variations of such scoring systems have attempted to optimize its prognostic value. More recently, minimally invasive surgical techniques are increasingly being used with promising results. As more patients become candidates for surgical intervention, there is a need to re-discuss the best methods for predicting outcomes with or without surgical intervention. METHODS We systematically performed a scoping review with a comprehensive literature search by two independent reviewers using the PubMed and Cochrane databases for articles pertaining to the "intracerebral hemorrhage score." Relevant articles were selected for analysis and discussion of potential modifications to account for increasing surgical indications. RESULTS A total of 64 articles were reviewed in depth and identified 37 clinical grading scales for prognostication of spontaneous intracerebral hemorrhage. The original ICH score remains the most widely used and validated. Various authors proposed modifications for improved prognostic accuracy, though no single scale showed consistent superiority. Most recently, scales to account for advances in surgical techniques have been developed but lack external validation. CONCLUSION We provide the most comprehensive review to date of prognostic grading scales for patients with intracerebral hemorrhage. Current prognostic tools for patients with intracerebral hemorrhage remain limited and may overestimate risk of a poor outcome. As minimally invasive surgical techniques are developed, prognostic scales should account for surgical candidacy and outcomes.

Abstract
The efficacy and safety of surgical treatment for intracerebral hemorrhage (ICH) have long been subjects of investigation and debate. The recent results of the minimally invasive surgery plus alteplase for intracerebral hemorrhage evacuation (MISTIE) III trial demonstrated the safety of the procedure and a reduction in mortality compared to medical treatment. Although no improvement in functional outcomes was shown, the trial elucidated that benefits of intervention depend on surgical performance: a greater ICH reduction, defined as ≤ 15 mL end of treatment ICH volume or ≥70% volume reduction, correlated with significant functional improvement. Recent meta-analyses suggested the benefits of neurosurgical hematoma evacuation, especially when performed earlier and done using minimally invasive procedures. In MISTIE III, to confirm hemostasis and reduce the risk of rebleeding, the mean time from onset to surgery and treatment completion took 47 and 123 h, respectively. Theoretically, the earlier the hematoma is removed, the better the outcome. Therefore, a higher rate of hematoma reduction within an earlier time course may be beneficial. Neuroendoscopic surgery enables less invasive removal of ICH under direct visualization. Minimally invasive procedures have continued to evolve with the support of advanced guidance systems and devices in favor of better surgical performance. Ongoing randomized controlled trials utilizing emerging minimally invasive techniques, such as the Early Minimally Invasive Removal of Intra Cerebral Hemorrhage (ENRICH) trial, Minimally Invasive Endoscopic Surgical Treatment with Apollo/Artemis in Patients with Brain Hemorrhage (INVEST) trial, and the Dutch Intracerebral Hemorrhage Surgery Trial (DIST), may provide significant information on the optimal treatment for ICH.

Abstract
BACKGROUND Multiple surgical techniques to perform minimally invasive intracerebral hemorrhage (ICH) evacuation are currently under investigation. The use of an adjunctive aspiration device permits controlled suction through an endoscope, minimizing collateral damage from the access tract. As with increased experience with any new procedure, performance of endoscopic minimally invasive ICH evacuation requires development of a unique set of operative tenets and techniques. OBJECTIVE To describe operative nuances of endoscopic minimally invasive ICH evacuation developed at a single center over an experience of 80 procedures. METHODS Endoscopic minimally invasive ICH evacuation was performed on 79 consecutive eligible patients who presented a single Health System between March 2016 and May 2018. We summarize 4 core operative tenets and 4 main techniques used in 80 procedures. RESULTS A total of 80 endoscopic minimally invasive ICH evacuations were performed utilizing the described surgical techniques. The average preoperative and postoperative volumes were 49.5 mL (standard deviation [SD] 31.1 mL, interquartile range [IQR] 30.2) and 5.4 mL (SD 9.6, mL IQR 5.1), respectively, with an average evacuation rate of 88.7%. All cause 30-d mortality was 8.9%. CONCLUSION As experience builds with endoscopic minimally invasive ICH evacuation, academic discussion of specific surgical techniques will be critical to maximizing its safety and efficacy.

Abstract
BACKGROUND Minimally invasive intracerebral hemorrhage (ICH) evacuation has gained popularity with success in early-phase clinical trials. This procedure, however, is performed in very different ways around the world. OBJECTIVE To provide a technical description of these strategies that facilitates comparison and aids decisions in which surgery to perform, and to inform further improvements in minimally invasive ICH evacuation. METHODS Major authors of clinical trials evaluating each of the main techniques were contacted and asked to supply a case example and technical description of their respective surgeries. RESULTS Five major techniques are presented including stereotactic thrombolysis, craniopuncture, endoscopic, endoscope-assisted, and endoport-mediated. Techniques differ in numerous ways including the size of the cranial access, the size of the access corridor through the brain to the hematoma, and the evacuation strategy. Regarding cranial access, a burr hole is created in stereotactic thrombolysis and craniopuncture, a small craniectomy in endoscopic, and a small craniotomy in the other 2. Access corridors through the parenchyma range from 3 mm in craniopuncture to 13.5 mm in the endoport-mediated evacuation. Regarding evacuation strategies, stereotactic thrombolysis and craniopuncture rely on passive drainage from a catheter placed during surgery that remains in place for multiple days, while the other 3 techniques rely on active evacuation with suction and bipolar cautery. CONCLUSION Future comparative clinical trials may identify the advantageous components of each strategy and contribute to improved outcomes in this patient population.

Abstract
BACKGROUND Many surgical procedures, such as placement of intracranial drains, are currently being performed blindly, relying on anatomical landmarks. As a result, accuracy results still have room for improvement. Neuronavigation could address this issue, but its application in an urgent setting is often impractical. Augmented reality (AR) provided through a head-worn device has the potential to tackle this problem, but its implementation should meet physicians' needs. METHODS The Surgical Augmented Reality Assistance (SARA) project aims to develop an AR solution that is suitable for preoperative planning, intraoperative visualisation and navigational support in an everyday clinical setting, using a Microsoft HoloLens. RESULTS Proprietary hardware and software adaptations and dedicated navigation algorithms are applied to the Microsoft HoloLens to optimise it specifically for neurosurgical navigation. This includes a pipeline with an additional set of advanced, semi-automated algorithms responsible for image processing, hologram-to-patient registration and intraoperative tracking using infrared depth-sensing. A smooth and efficient workflow while maintaining high accuracy is prioritised. The AR solution provides a fully integrated and completely mobile navigation setup. Initial preclinical and clinical validation tests applying the solution to intracranial drain placement are described. CONCLUSION AR has the potential to vastly increase accuracy of everyday procedures that are frequently performed without image guidance, but could still benefit from navigational support, such as intracranial drain placements. Technical development should go hand in hand with preclinical and clinical validation in order to demonstrate improvements in accuracy and clinical outcomes.

Abstract
BACKGROUND/OBJECTIVE Demonstrating a benefit of acute treatment to patients with intracerebral hemorrhage (ICH) requires identifying which patients have a potentially modifiable outcome, where treatment could favorably shift a patient's expected outcome. A decision rule for which patients have a modifiable outcome could improve the targeting of treatments. We sought to determine which patients with ICH have a modifiable outcome. METHODS Patients with ICH were prospectively identified at two institutions. Data on hematoma volumes, medication histories, and other variables of interest were collected. ICH outcomes were evaluated using the modified Rankin Scale (mRS), assessed at 14 days and 3 months after ICH, with "good outcome" defined as 0-3 (independence or better) and "poor outcome" defined as 4-6 (dependence or worse). Supervised machine learning models identified the best predictors of good versus poor outcomes at Institution 1. Models were validated using repeated fivefold cross-validation as well as testing on the entirely independent sample at Institution 2. Model fit was assessed with area under the ROC curve (AUC). RESULTS Model performance at Institution 1 was strong for both 14-day (AUC of 0.79 [0.77, 0.81] for decision tree, 0.85 [0.84, 0.87] for random forest) and 3 month (AUC of 0.75 [0.73, 0.77] for decision tree, 0.82 [0.80, 0.84] for random forest) outcomes. Independent predictors of functional outcome selected by the algorithms as important included hematoma volume at hospital admission, hematoma expansion, intraventricular hemorrhage, overall ICH Score, and Glasgow Coma Scale. Hematoma expansion was the only potentially modifiable independent predictor of outcome and was compatible with "good" or "poor" outcome in a subset of patients with low hematoma volumes, good Glasgow Coma scale and premorbid modified Rankin Scale scores. Models trained on harmonized data also predicted patient outcomes well at Institution 2 using decision tree (AUC 0.69 [0.63, 0.75]) and random forests (AUC 0.78 [0.72, 0.84]). CONCLUSIONS Patient outcomes are predictable to a high level in patients with ICH, and hematoma expansion is the sole-modifiable predictor of these outcomes across two outcome types and modeling approaches. According to decision tree analyses predicting outcome at 3 months, patients with a high Glasgow Coma Scale score, less than 44.5 mL hematoma volume at admission, and relatively low premorbid modified Rankin Score in particular have a modifiable outcome and appear to be candidates for future interventions to improve outcomes after ICH.

The Latest View on the Mechanism of Ferroptosis and Its Research Progress in Spinal Cord Injury. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:6375938. [PMID: 32908634 PMCID: PMC7474794 DOI: 10.1155/2020/6375938] [Citation(s) in RCA: 46] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Accepted: 07/27/2020] [Indexed: 01/08/2023]
Abstract
Ferroptosis is a recently identified nonapoptotic form of cell death whose major markers are iron dependence and accumulation of lipid reactive oxygen species, accompanied by morphological changes such as shrunken mitochondria and increased membrane density. It appears to contribute to the death of tumors, ischemia-reperfusion, acute renal failure, and nervous system diseases, among others. The generative mechanism of ferroptosis includes iron overloading, lipid peroxidation, and downstream execution, while the regulatory mechanism involves the glutathione/glutathione peroxidase 4 pathway, as well as the mevalonate pathway and the transsulfuration pathway. In-depth research has continuously developed and enriched knowledge on the mechanism by which ferroptosis occurs. In recent years, reports of the noninterchangeable role played by selenium in glutathione peroxidase 4 and its function in suppressing ferroptosis and the discovery of ferroptosis suppressor protein 1, identified as a ferroptosis resistance factor parallel to the glutathione peroxidase 4 pathway, have expanded and deepened our understanding of the mechanism by which ferroptosis works. Ferroptosis has been reported in spinal cord injury animal model experiments, and the inhibition of ferroptosis could promote the recovery of neurological function. Here, we review the latest studies on mechanism by which ferroptosis occurs, focusing on the ferroptosis execution and the contents related to selenium and ferroptosis suppressor protein 1. In addition, we summarize the current research status of ferroptosis in spinal cord injury. The aim of this review is to better understand the mechanisms by which ferroptosis occurs and its role in the pathophysiological process of spinal cord injury, so as to provide a new idea and frame of reference for further exploration.

Abstract
BACKGROUND Minimally invasive surgery procedures, including stereotactic catheter aspiration and clearance of intracerebral hemorrhage (ICH) with recombinant tissue plasminogen activator hold a promise to improve outcome of supratentorial brain hemorrhage, a morbid and disabling type of stroke. A recently completed Phase III randomized trial showed improved mortality but was neutral on the primary outcome (modified Rankin scale score 0 to 3 at 1 yr). OBJECTIVE To assess surgical performance and its impact on the extent of ICH evacuation and functional outcomes. METHODS Univariate and multivariate models were used to assess the extent of hematoma evacuation efficacy in relation to mRS 0 to 3 outcome and postulated factors related to patient, disease, and protocol adherence in the surgical arm (n = 242) of the MISTIE trial. RESULTS Greater ICH reduction has a higher likelihood of achieving mRS of 0 to 3 with a minimum evacuation threshold of ≤15 mL end of treatment ICH volume or ≥70% volume reduction when controlling for disease severity factors. Mortality benefit was achieved at ≤30 mL end of treatment ICH volume, or >53% volume reduction. Initial hematoma volume, history of hypertension, irregular-shaped hematoma, number of alteplase doses given, surgical protocol deviations, and catheter manipulation problems were significant factors in failing to achieve ≤15 mL goal evacuation. Greater surgeon/site experiences were associated with avoiding poor hematoma evacuation. CONCLUSION This is the first surgical trial reporting thresholds for reduction of ICH volume correlating with improved mortality and functional outcomes. To realize the benefit of surgery, protocol objectives, surgeon education, technical enhancements, and case selection should be focused on this goal.

[PMID: 32080781 DOI: 10.1007/s10143-020-01252-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2019] [Revised: 12/18/2019] [Accepted: 01/23/2020] [Indexed: 11/29/2022]
Abstract
Stereotactic removal of intracerebral hematoma is a routine procedure for treating hypertensive intracerebral hemorrhage, but the complex sequence of operations limits its adoption. We explored the application of a novel surgical technique for the removal of spontaneous intracerebral hematomas. The surgical technique based on computed tomography (CT) images was used in hematoma projection and surgical planning. Markers placed on the scalp based on an Android smartphone app allowed the installation of a stereotactic head frame to facilitate the selection of the best trajectory to the hematoma center for removing the hematoma. Forty-two patients with spontaneous intracerebral hemorrhage were included in the study, including 33 cases of supratentorial hemorrhage, 5 cases of cerebellum hemorrhage, and 4 cases of brain stem hemorrhage. The surgical technique combined with the stereotactic head frame helped the tip of the drainage tube achieve the desired position. The median surgical time was 45 (range 25-75) min. The actual head frame operating time was 10 (range 5-15) min. Target alignment performed by the surgical technique was accurate to ≤ 10.0 mm in all 42 cases. No patient experienced postoperative rebleeding. In 33 cases of supratentorial intracerebral hemorrhage, an average evacuation rate of 77.5% was achieved at postoperative 3.1 ± 1.4 days, and 29 (87.9%) cases had a residual hematoma of < 15 ml. The novel surgical technique helped to quickly and effortlessly localize hematomas and achieve satisfactory hematoma removal. Clinical application of the stereotactic head frame was feasible for intracerebral hemorrhage in various locations.

Abstract
Spontaneous intracerebral hemorrhage is a devastating disease, accounting for 10 to 15% of all types of stroke; however, it is associated with disproportionally higher rates of mortality and disability. Despite significant progress in the acute management of these patients, the ideal surgical management is still to be determined. Surgical hematoma drainage has many theoretical benefits, such as the prevention of mass effect and cerebral herniation, reduction in intracranial pressure, and the decrease of excitotoxicity and neurotoxicity of blood products. Several surgical techniques have been considered, such as open craniotomy, decompressive craniectomy, neuroendoscopy, and minimally invasive catheter evacuation followed by thrombolysis. Open craniotomy is the most studied approach in this clinical scenario, the first randomized controlled trial dating from the early 1960s. Since then, a large number of studies have been published, which included two large, well-designed, well-powered, multicenter, multinational, randomized clinical trials. These studies, The International Surgical Trial in Intracerebral Hemorrhage (STICH), and the STICH II have shown no clinical benefit for early surgical evacuation of intraparenchymal hematoma in patients with spontaneous supratentorial hemorrhage when compared with best medical management plus delayed surgery if necessary. However, the results of STICH trials may not be generalizable, because of the high rates of patients’ crossover from medical management to the surgical group. Without these high crossover percentages, the rates of unfavorable outcome and death with conservative management would have been higher. Additionally, comatose patients and patients at risk of cerebral herniation were not included. In these cases, surgery may be lifesaving, which prevented those patients of being enrolled in such trials. This article reviews the clinical evidence of surgical hematoma evacuation, and its role to decrease mortality and improve long-term functional outcome after spontaneous intracerebral hemorrhage.

Abstract
Intracerebral hemorrhage in combination with intraventricular hemorrhage (IVH) is a severe type of stroke frequently leading to prolonged clinical care, continuous disability, shunt dependency, and high mortality. The molecular mechanisms induced by IVH are complex and not fully understood. Moreover, the treatment options for IVH are limited. Intraventricular recombinant tissue plasminogen activator (rt-PA) dissolves the blood clot in the ventricular system; however, whether the clinical outcome is thereby positively affected is still being debated. The mechanistic cascade induced by intraventricular rt-PA therapy may cure and harm in parallel. Despite the fact that intraventricular blood clots are thereby dissolved, blood derivatives enter the parenchyma and may still adversely affect functional structures of the brain: Smaller blood clots may obstruct the perivascular (Virchow-Robin) space and thereby the glymphatic system with detrimental consequences for cerebrospinal fluid (CSF)/interstitial fluid (ISF) flow. These clots, blood cells but also blood derivatives in the perivascular space, destabilize the blood-brain barrier from the brain parenchyma side, thereby also functionally weakening the neurovascular unit. This may lead to further accommodation of serum proteins in the ISF and particularly in the perivascular space further contributing to the adverse effects on the neuronal microenvironment. Finally, the arterial (Pacchionian) granulations have to cope with ISF containing this "blood, cell, and protein cocktail," resulting in obstruction and insufficient function of the arterial granulations, followed by a malresorptive hydrocephalus. Particularly in light of currently improved knowledge on the physiologic and pathophysiologic clearance of cerebrospinal fluid and interstitial fluid, a critical discussion and reevaluation of our current therapeutic strategies to treat intraventricular hemorrhages are needed to successfully treat patients suffering from this severe type of stroke. In this review, we therefore summarize and discuss recent clinical trials and future directions for the field of IVH with respect to the currently increased understanding of the glymphatic system and the neurovascular unit pathophysiology.

Abstract
OBJECTIVES Decision making for surgical therapy in patients with intracerebral hemorrhage is still controversial among neurologists and neurosurgeons. Whereas neurologists may favor conservative treatments, surgeons may opt for operations. This might lead to different therapy decisions. PATIENTS AND METHODS Between 2017 and 2018, we conducted a survey among the neurological and neurosurgical societies in Germany. An online questionnaire consisting of 10 fictive patients with spontaneous supratentorial intracerebral hemorrhage (including CT scans and brief case descriptions) was administered to the members of the societies. The participants were asked to decide whether conservative or surgical treatment would be preferred. Furthermore, the results from the neurosurgeons were compared to the results of our previous surveys in 1999 and 2009. RESULTS A total of 157 answers were collected (response rate of 16.2%). Nineteen had to be excluded, leaving 138 for analysis (84 neurosurgeons and 54 neurologists). There were no significant differences in therapy decisions between neurologists and neurosurgeons in all ten cases. Comparing the answers from neurosurgeons with our previous results, there were no significant differences between the results from 1999, 2009 and 2017. CONCLUSIONS Against common prejudices, the process of decision making for or against surgery in patients with spontaneous intracerebral hemorrhage is comparable among conservative physicians (neurologists) and neurosurgeons in Germany. This might be the result of joint efforts in spontaneous intracerebral hemorrhage (ICH) therapy, such as joint guidelines or a society of neurointensive care medicine.

Targeting neutrophil extracellular traps enhanced tPA fibrinolysis for experimental intracerebral hemorrhage. Transl Res 2019; 211:139-146.

Abstract
The minimally invasive surgery plus fibrinolysis has been identified as a promising treatment for spontaneous intracerebral hemorrhage (ICH). However, the fibrinolytic efficacy is not satisfactory. Neutrophil extracellular traps (NETs) have been demonstrated to impair fibrinolysis in sepsis and acute ischemic stroke. Therefore, we decided to explore the presence and potential effect of NETs in ICH fibrinolysis. Intracerebral hemorrhage was induced by autologous arterial blood injection into the basal ganglia in rats. First, at 0.5 hour, 1 hour, and 1.5 hours after blood injection, the brains were collected for NETs detection by immune-staining. Second, ICH rats were given intrahematoma fibrinolysis: rats were randomized to receive the equal amount of saline, DNAse 1, tissue-plasminogen activator (tPA), and tPA + DNAse 1 at 1 hour after hematoma placement. On day 3, animals were sacrificed for terminal deoxynucleotidyl transferase-mediated dUTP Nick-end labeling staining following MRI and behavioral tests. Third, on day 3 after ICH, the hematoma within brain were collected for ex vivo fibrinolysis assay to further evaluate the effect of NETs in ICH fibrinolysis. Co-staining of DAPI, H3, and MPO confirmed the presence of NETs in ICH. Disintegration of NETs using DNAse 1 enhanced tPA-induced hematoma fibrinolysis, relieved brain swelling, reduced cell death, and improved the functional outcome in ICH rats. Therefore, we concluded that NETs impaired the efficacy of tPA for ICH fibrinolysis in rats. Targeting NETs may be a new alternative to improve the fibrinolytic therapy following ICH.

Abstract
Ferroptosis, a non-apoptotic form of programmed cell death, is triggered by oxidative stress in cancer, heat stress in plants, and hemorrhagic stroke. A homeostatic transcriptional response to ferroptotic stimuli is unknown. We show that neurons respond to ferroptotic stimuli by induction of selenoproteins, including antioxidant glutathione peroxidase 4 (GPX4). Pharmacological selenium (Se) augments GPX4 and other genes in this transcriptional program, the selenome, via coordinated activation of the transcription factors TFAP2c and Sp1 to protect neurons. Remarkably, a single dose of Se delivered into the brain drives antioxidant GPX4 expression, protects neurons, and improves behavior in a hemorrhagic stroke model. Altogether, we show that pharmacological Se supplementation effectively inhibits GPX4-dependent ferroptotic death as well as cell death induced by excitotoxicity or ER stress, which are GPX4 independent. Systemic administration of a brain-penetrant selenopeptide activates homeostatic transcription to inhibit cell death and improves function when delivered after hemorrhagic or ischemic stroke.

Abstract
BACKGROUND Acute stroke due to supratentorial intracerebral haemorrhage is associated with high morbidity and mortality. Open craniotomy haematoma evacuation has not been found to have any benefit in large randomised trials. We assessed whether minimally invasive catheter evacuation followed by thrombolysis (MISTIE), with the aim of decreasing clot size to 15 mL or less, would improve functional outcome in patients with intracerebral haemorrhage. METHODS MISTIE III was an open-label, blinded endpoint, phase 3 trial done at 78 hospitals in the USA, Canada, Europe, Australia, and Asia. We enrolled patients aged 18 years or older with spontaneous, non-traumatic, supratentorial intracerebral haemorrhage of 30 mL or more. We used a computer-generated number sequence with a block size of four or six to centrally randomise patients to image-guided MISTIE treatment (1·0 mg alteplase every 8 h for up to nine doses) or standard medical care. Primary outcome was good functional outcome, defined as the proportion of patients who achieved a modified Rankin Scale (mRS) score of 0-3 at 365 days, adjusted for group differences in prespecified baseline covariates (stability intracerebral haemorrhage size, age, Glasgow Coma Scale, stability intraventricular haemorrhage size, and clot location). Analysis of the primary efficacy outcome was done in the modified intention-to-treat (mITT) population, which included all eligible, randomly assigned patients who were exposed to treatment. All randomly assigned patients were included in the safety analysis. This study is registered with ClinicalTrials.gov, number NCT01827046. FINDINGS Between Dec 30, 2013, and Aug 15, 2017, 506 patients were randomly allocated: 255 (50%) to the MISTIE group and 251 (50%) to standard medical care. 499 patients (n=250 in the MISTIE group; n=249 in the standard medical care group) received treatment and were included in the mITT analysis set. The mITT primary adjusted efficacy analysis estimated that 45% of patients in the MISTIE group and 41% patients in the standard medical care group had achieved an mRS score of 0-3 at 365 days (adjusted risk difference 4% [95% CI -4 to 12]; p=0·33). Sensitivity analyses of 365-day mRS using generalised ordered logistic regression models adjusted for baseline variables showed that the estimated odds ratios comparing MISTIE with standard medical care for mRS scores higher than 5 versus 5 or less, higher than 4 versus 4 or less, higher than 3 versus 3 or less, and higher than 2 versus 2 or less were 0·60 (p=0·03), 0·84 (p=0·42), 0·87 (p=0·49), and 0·82 (p=0·44), respectively. At 7 days, two (1%) of 255 patients in the MISTIE group and ten (4%) of 251 patients in the standard medical care group had died (p=0·02) and at 30 days, 24 (9%) patients in the MISTIE group and 37 (15%) patients in the standard medical care group had died (p=0·07). The number of patients with symptomatic bleeding and brain bacterial infections was similar between the MISTIE and standard medical care groups (six [2%] of 255 patients vs three [1%] of 251 patients; p=0·33 for symptomatic bleeding; two [1%] of 255 patients vs 0 [0%] of 251 patients; p=0·16 for brain bacterial infections). At 30 days, 76 (30%) of 255 patients in the MISTIE group and 84 (33%) of 251 patients in the standard medical care group had one or more serious adverse event, and the difference in number of serious adverse events between the groups was statistically significant (p=0·012). INTERPRETATION For moderate to large intracerebral haemorrhage, MISTIE did not improve the proportion of patients who achieved a good response 365 days after intracerebral haemorrhage. The procedure was safely adopted by our sample of surgeons. FUNDING National Institute of Neurological Disorders and Stroke and Genentech.

Stroke aetiological classification reliability and effect on trial sample size: systematic review, meta-analysis and statistical modelling. Trials 2019; 20:107.

Abstract
Background Inter-observer variability in stroke aetiological classification may have an effect on trial power and estimation of treatment effect. We modelled the effect of misclassification on required sample size in a hypothetical cardioembolic (CE) stroke trial. Methods We performed a systematic review to quantify the reliability (inter-observer variability) of various stroke aetiological classification systems. We then modelled the effect of this misclassification in a hypothetical trial of anticoagulant in CE stroke contaminated by patients with non-cardioembolic (non-CE) stroke aetiology. Rates of misclassification were based on the summary reliability estimates from our systematic review. We randomly sampled data from previous acute trials in CE and non-CE participants, using the Virtual International Stroke Trials Archive. We used bootstrapping to model the effect of varying misclassification rates on sample size required to detect a between-group treatment effect across 5000 permutations. We described outcomes in terms of survival and stroke recurrence censored at 90 days. Results From 4655 titles, we found 14 articles describing three stroke classification systems. The inter-observer reliability of the classification systems varied from ‘fair’ to ‘very good’ and suggested misclassification rates of 5% and 20% for our modelling. The hypothetical trial, with 80% power and alpha 0.05, was able to show a difference in survival between anticoagulant and antiplatelet in CE with a sample size of 198 in both trial arms. Contamination of both arms with 5% misclassified participants inflated the required sample size to 237 and with 20% misclassification inflated the required sample size to 352, for equivalent trial power. For an outcome of stroke recurrence using the same data, base-case estimated sample size for 80% power and alpha 0.05 was n = 502 in each arm, increasing to 605 at 5% contamination and 973 at 20% contamination. Conclusions Stroke aetiological classification systems suffer from inter-observer variability, and the resulting misclassification may limit trial power.

Abstract
Stroke, either ischemic or hemorrhagic, accounts for significantly high morbidity and mortality rates around the globe effecting millions of lives annually. For the past few decades, ultrasound has been extensively investigated to promote clot lysis for the treatment of stroke, myocardial infarction, and acute peripheral arterial occlusions, with or without the use of tPA or contrast agents. In the age of modern minimal invasive techniques, magnetic resonance imaging-guided high-intensity focused ultrasound is a new emerging modality that seems to promise therapeutic utilities for both ischemic and hemorrhagic stroke. High-intensity focused ultrasound causes thermal heating as the tissue absorbs the mechanical energy transmitted by the ultrasonic waves leading to tissue denaturation and coagulation. Several in-vitro and in-vivo studies have demonstrated the viability of this technology for sonothrombolysis in both types of stroke and have warranted clinical trials. Apart from safety and efficacy, initiation of trials would further enable answers regarding its practical application in a clinical setup. Though this technology has been under study for treatment of various brain diseases for some decades now, relatively very few neurologists and even neurosurgeons seem to be acquainted with it. The aim of this review is to provide basic understanding of this powerful technology and discuss its clinical application and potential role as an emerging viable therapeutic option for the future management of stroke.

Abstract
INTRODUCTION Intracerebral hemorrhage (ICH) is associated with a high rate of morbidity and mortality. Minimally-invasive surgery (MIS) has been increasingly used in recent years. We systematically reviewed the role of MIS in the acute management of ICH using various techniques. EVIDENCE ACQUISITION A comprehensive electronic search for relevant articles was conducted on several relevant international databases, including PUBMED (Medline), EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL). EVIDENCE SYNTHESIS Our primary literature research resulted in 1134 articles. In total, 116 publications finally met the eligibility criteria to be included in our systematic review. Five major MIS categories for the evacuation of ICH were identified, respectively: minimally invasive direct aspiration with or without thrombolytics, endoscope assisted technique, sonothrombolysis, aspiration-irrigation device and endoport-assisted evacuation. CONCLUSIONS The role of minimally invasive techniques in the management of ICH remains under dispute. However, a mounting evidence in the literature demonstrates that MIS is associated with significantly improved outcomes when compared with conservative treatment and conventional surgical evacuation strategy.

Abstract
OBJECTIVE To investigate the association between ultraearly hematoma growth (uHG) and clinical outcome in patients with spontaneous intracerebral hemorrhage (sICH) receiving hematoma evacuation. METHODS Supratentorial sICH patients receiving hematoma evacuation within 24 hours after ictus were enrolled in this study. uHG was defined as baseline hematoma volume/onset-to-computed tomography (CT) time (mL/h). The outcome was assessed by the modified Rankin Scale (mRS) score at 3 months. Unfavorable outcome was defined as mRS >2. RESULTS A total of 93 patients were enrolled in this study. The mean uHG was 10.3 ± 5.5 mL/h. In 69 (74.2%) of patients, the outcome was unfavorable at 3 months. The uHG in patients with unfavorable outcome were significantly higher than in those with favorable outcome (11.0 ± 6.1 mL/h vs. 8.3 ± 2.5 mL/h, P = 0.003). The optimal cutoff of uHG for predicting unfavorable outcome was 8.7 mL/h. The sensitivity, specificity, positive predictive value, and negative predictive value of uHG >8.7 mL/h for predicting unfavorable outcome were 56.5%, 75.0%, 86.7%, and 37.5%, respectively. CONCLUSIONS uHG is a helpful predictor of unfavorable outcome in sICH patients treated with hematoma evacuation. The optimal cutoff of uHG to assist in predicting unfavorable outcome in sICH patients receiving hematoma evacuation is 8.7mL/h.
