Abstract
Intraventricular hemorrhage (IVH) is a complication of a spontaneous intracerebral hemorrhage. Standard treatment is with external ventricular drain (EVD). Intraventricular thrombolysis may improve mortality but does not improve functional outcomes. We present our initial experience with a novel irrigating EVD (IRRAflow) that automates continuous irrigation with thrombolysis.Single-center case-control study including patients with IVH treated with EVD compared to IRRAflow. We compared standard demographics, treatment, and outcome parameters between groups. We developed a brain phantom injected with a human clot and assessed clot clearance using EVD/IRRAflow approaches with CT imaging.Twenty-one patients were treated with standard EVD and 9 patients with IRRAflow. Demographics were similar between groups. Thirty-three percent of patients with EVD also had at least one dose of t-PA and 89% of patients with IRRAflow received irrigation with t-PA (p = 0.01). Mean drain days were 8.8 for EVD versus 4.1 for IRRAflow (p = 0.02). Days-to-clearance of ventricular outflow was 5.8 for EVD versus 2.5 for IRRAflow (p = 0.02). Overall clearance was not different. Thirty-seven percent of EVD patients achieved good outcome (mRS ≥ 3) at 90 days versus 86% of IRRAflow patients (p = 0.03). Assessing only t-PA, reduction in mean days-to-clearance (p = 0.0004) and ICU days (p = 0.04) was observed. In the benchtop model, the clot treated with IRRAflow and t-PA showed a significant reduction of volume compared to control.Irrigation with IRRAflow and t-PA is feasible and safe for patients with IVH. Improving clot clearance with IRRAflow may result in improved clinical outcomes and should be incorporated into randomized trials.

Abstract
BACKGROUND Intraventricular hemorrhage (IVH) is a type of ventricular bleeding that results in significant morbidity and mortality. Multiple studies have investigated the use of urokinase in IVH treatment. The use of urokinase may lead to higher rates of hematoma resolution and lower mortality rates. However, further studies are required to determine efficacy of urokinase administration. This study examined the association between urokinase use, IVH volume reduction, and clinical outcomes. METHODS In total, 94 adult patients with hypertensive intracerebral hemorrhage with ventricular extension or primary IVH were enrolled between 2015 and 2021. Participants were categorized into two groups: "EVD combined with fibrinolysis" and "EVD only." The primary objective was to assess the reduction of IVH severity. Additionally, the study evaluated the functional outcomes and shunt dependency rate as secondary outcomes. Non-contrast computed tomography scans were obtained to measure the severity of IVH using the mGRAEB score. The main outcomes were the association among urokinase administration, reduced IVH severity, and functional outcomes. RESULTS There were no significant differences in the reduction rate of mGRAEB scores within a 7-day period (-50.0 [-64.4 to -32.5] % vs -44.2 [-59.3 to -7.9] %; p = 0.489). In addition, investigation of the third and fourth ventricles showed similar findings between the two groups. Urokinase treatment was not associated with significant differences in the modified Rankin Scale (5.0 (4.0-5.0) vs. 4.5 (4.0-5.0), p = 0.674) or shunt dependency rate (33.3% vs 39.3%, p = 0.58). CONCLUSION This study found that intraventricular urokinase use in patients with IVH was not associated with reduced IVH severity. In addition, urokinase use was not associated with better functional outcomes or minor shunt dependency rates.

Abstract
BACKGROUND In patients with intracerebral hemorrhage (ICH), the presence of intraventricular hemorrhage constitutes a promising therapeutic target. Intraventricular fibrinolysis (IVF) reduces mortality, yet impact on functional disability remains unclear. Thus, we aimed to determine the influence of IVF on functional outcomes. METHODS This individual participant data meta-analysis pooled 1501 patients from 2 randomized trials and 7 observational studies enrolled during 2004 to 2015. We compared IVF versus standard of care (including placebo) in patients treated with external ventricular drainage due to acute hydrocephalus caused by ICH with intraventricular hemorrhage. The primary outcome was functional disability evaluated by the modified Rankin Scale (mRS; range: 0-6, lower scores indicating less disability) at 6 months, dichotomized into mRS score: 0 to 3 versus mRS: 4 to 6. Secondary outcomes included ordinal-shift analysis, all-cause mortality, and intracranial adverse events. Confounding and bias were adjusted by random effects and doubly robust models to calculate odds ratios and absolute treatment effects (ATE). RESULTS Comparing treatment of 596 with IVF to 905 with standard of care resulted in an ATE to achieve the primary outcome of 9.3% (95% CI, 4.4-14.1). IVF treatment showed a significant shift towards improved outcome across the entire range of mRS estimates, common odds ratio, 1.75 (95% CI, 1.39-2.17), reduced mortality, odds ratio, 0.47 (95% CI, 0.35-0.64), without increased adverse events, absolute difference, 1.0% (95% CI, -2.7 to 4.8). Exploratory analyses provided that early IVF treatment (≤48 hours) after symptom onset was associated with an ATE, 15.2% (95% CI, 8.6-21.8) to achieve the primary outcome. CONCLUSIONS As compared to standard of care, the administration of IVF in patients with acute hydrocephalus caused by intracerebral and intraventricular hemorrhage was significantly associated with improved functional outcome at 6 months. The treatment effect was linked to an early time window <48 hours, specifying a target population for future trials.

Abstract
Spontaneous intracerebral hemorrhage (ICH), especially related to intraventricular hemorrhage (IVH), is the most devastating type of stroke and is associated with high mortality and morbidity. Optimal management of ICH remains one of the most controversial areas of neurosurgery and no effective treatment exists for ICH. Studies comparing conventional surgical interventions with optimal medical management failed to show significant benefit. Recent exploration of minimally invasive surgery for ICH and IVH including catheter- and mechanical-based approaches has shown great promise. Early phase clinical trials have confirmed the safety and preliminary treatment effect of minimally invasive surgery for ICH and IVH. Pending efficacy data from phase III trials dealing with diverse minimally invasive techniques are likely to shape the treatment of ICH.

Abstract
BACKGROUND We compare the effect of urokinase (urokinase-type plasminogen activator [uPA]) versus alteplase (recombinant tissue plasminogen activator [rt-PA]) for intraventricular fibrinolysis (IVF) in patients with intraventricular hemorrhage (IVH) on ventriculoperitoneal shunt (VPS) dependence, functional outcome, and complications in the management of IVH. METHODS We retrospectively reviewed the patients admitted with IVH or intracerebral hemorrhage (ICH) with IVH within 7 years in three different departments and found 102 patients who met the inclusion criteria. The primary end points were VPS dependence and Glasgow outcome score (GOS) at 3 months. Secondary end points were rate of rebleeding under IVF and incidence of treatment-related complications. Patients were divided into three groups: group I comprised patients treated with external ventricular drain (EVD) and IVF with uPA; group II comprised patients treated with EVD and IVF with rt-PA; and group III comprised patients treated with EVD alone. RESULTS In all, 9.8% patients needed VPS: 12.2% in group I and 15.0% in group II, with no statistically significant difference. VPS patients had higher values of the modified Graeb score (mGS), IVH score, and IVH volume. We saw a trend for a better outcome in group II, with six patients achieving a GOS of 4 or 5 after 3 months. The mortality rate was higher in groups I and III. We found no statistical difference in the complication rate between groups I and II. Logistic regression analysis revealed that higher mGS and age predicted worse prognosis concerning mortality. The risk for death rose by 7.8% for each year of age. Any additional mGS point increased the chances of death by 9.7%. CONCLUSION Our data suggest that both uPA and rt-PA are safe and comparable regarding incidence of communicating hydrocephalus, and age and mGS are predictive for mortality.

Abstract
Intraventricular hemorrhage is a serious intracerebral hemorrhagic disease with high mortality and poor prognosis. This retrospective study designed to investigate the therapeutic effect of transcortical approach surgery versus extraventricular drainage (EVD) on patients with intraventricular hemorrhage.Patients with intraventricular hemorrhage in Zhongshan City People's Hospital from January 01, 2014 to June 01, 2019 were retrospectively examined. They were divided into transcortical approach surgery groups and EVD groups to analyze the clinical characteristics and prognosis.A total of 96 patients were enrolled in the study (24 in the transcortical approach surgery group and 72 in the EVD group). The efficiency of postoperative operation was 15/19 in the transcortical approach surgery group and 24/48 in the EVD group (P = .012). The Glasgow Outcome Scale was 3.63 ± 1.27 in the transcortical approach surgery group and 2.80 ± 1.87 in the EVD group (P = .049). The postoperative residual blood volume was 9.62 ± 3.64 mL in the transcortical approach surgery group and 33.60 ± 3.53 mL in the EVD group (P < .001). The incidence of hydrocephalus after the operation was 1/23 in the transcortical approach surgery group and 19/53 in the EVD group. The 30-day postoperative mortality was 16/56 in the EVD group and 1/23 in the transcortical approach surgery group. The transcortical approach surgery group was significantly better compared with the EVD group.This study showed that the transcortical approach for ventricular hemorrhage compared with EVD improved the hematoma clearance rate, shortened catheterization time, reduced the incidence of postoperative hydrocephalus, decreased patient mortality, led to a better prognosis, and reduced complications of hydrocephalus.

Abstract
OBJECTIVE To explore which intraventricular fibrinolytic agent - urokinase (UK) or recombinant tissue plasminogen activator (rt-PA) - combined with extraventricular drainage (EVD) is most suitable for patients with spontaneous intraventricular hemorrhage (IVH). PATIENTS AND METHODS We searched PubMed, MEDLINE, OVID, Embase, and Cochrane Library databases for relevant articles and assessed their quality and extracted statistical analyses using Stata 13.0 and Revman 5.3 software. RESULTS Compared with EVD alone, EVD combined with an agent causing intraventricular fibrinolysis (IVF) improved the survival and prognosis of patients with IVH. Regarding the patients' survival rates and prognoses, the treatments, from best to worst results were EVD + UK, EVD + rt-PA, EVD alone. The proportion of patients with serious disability also increased with these treatments, however, with the highest to lowest proportions being EVD + rt-PA, EVD + UK, EVD alone. In addition, EVD + IVF was associated with a higher risk of intracranial rebleeding (from lowest to highest incidence: EVD alone, EVD + rt-PA, EVD + UK). Finally, EVD + UK is associated with an increased risk of potential intracranial infection (from lowest to highest incidence: EVD + rt-PA, EVD alone, EVD + UK). CONCLUSIONS EVD + UK may be the best approach to improving patients' survival rate and prognosis. However, it also presents the highest risk of intracranial infection and rebleeding. EVD + IVF increased the proportion of patients with serious disability.

Abstract
Intraventricular hemorrhage (IVH) is an independent poor prognostic factor in subarachnoid and intra-parenchymal hemorrhage. The use of intraventricular fibrinolytics (IVF) has long been debated, and its exact effects on outcomes are unknown. A systematic review and meta-analysis were performed in accordance with the PRISMA guidelines to assess the impact of IVF after non-traumatic IVH on mortality, functional outcome, intracranial bleeding, ventriculitis, time until clearance of third and fourth ventricles, obstruction of external ventricular drains (EVD), and shunt dependency. Nineteen studies were included in the meta-analysis, totaling 1020 patients. IVF was associated with lower mortality (relative risk [RR] 0.58; 95% confidence interval [CI] 0.47-0.72), fewer EVD obstructions (RR 0.41; 95% CI 0.22-0.74), and a shorter time until clearance of the ventricles (median difference [MD] - 4.05 days; 95% CI - 5.52 to - 2.57). There was no difference in good functional outcome, RR 1.41 (95% CI 0.98-2.03), or shunt dependency, RR 0.93 (95% CI 0.70-1.22). Correction for publication bias predicted an increased risk of intracranial bleeding, RR 1.67 (95% CI 1.01-2.74) and a lower risk of ventriculitis, RR 0.68 (95% CI 0.45-1.03) in IVH patients treated with IVF. IVF was associated with improved survival, faster clearance of blood from the ventricles and fewer drain obstructions, but further research is warranted to elucidate the effects on ventriculitis, long-term functional outcomes, and re-hemorrhage.

Abstract
OBJECTIVE To explore whether endoscopy surgery (ES) and extraventricular drainage (EVD) combined with intraventricular fibrinolytic (IVF) are superior to EVD alone in patients with intraventricular hemorrhage (IVH) and to determine which procedure is more suitable in such patients. METHODS We searched the following databases: PubMed, MEDLINE, Ovid, Embase, and Cochrane Library. Randomized controlled trials and nonrandomized studies comparing ≥2 different interventions in patients with IVH were included. The quality of the included studies was assessed. Pairwise and network meta-analysis were performed using software Stata 13.0 and Revman 5.3. RESULTS Compared with the EVD-alone intervention, the ES regimen, EVD combined with urokinase (UK), and EVD combined with recombinant tissue plasminogen activator (rt-PA) regimens all resulted in better survival and prognosis in patients with IVH. For both survival rate and prognosis, the order from best to worst was ES, EVD combined with UK, EVD combined with rt-PA, and EVD-alone. However, EVD combined with IVF had a high risk of intracranial rebleeding; the order of intracranial rebleeding risk from lowest to highest was ES, EVD-alone, EVD combined with rt-PA, and EVD combined with UK. The risk of intracranial infection in EVD combined with rt-PA was lower than that of EVD-alone, but EVD combined with UK also had a higher risk than did EVD-alone. The risk of intracranial infection from lowest to the highest was ES, EVD combined with rt-PA, EVD-alone, and EVD combined with UK. CONCLUSIONS Our analysis showed that ES is more suitable for patients with IVH. ES not only improved the survival and prognosis but also had the lowest risk of ventriculoperitoneal shunt and intracranial rebleeding or infection.

Abstract
Background Intraventricular hemorrhage is a significant cause of mortality and morbidity worldwide. Treating intraventricular hemorrhage with intraventricular fibrinolytic therapy via a catheter is becoming an increasingly utilized intervention. Aims This meta-analysis aimed to investigate the role of intraventricular fibrinolytic treatment in hypertensive intraventricular hemorrhage patients and evaluate the effect sizes for survival as well as level of function at differing time points. Summary of review PubMed, CNKI, VIP, and Wanfang were searched using the terms "IVH" and "IVH and ICH" for human studies with adult patients published between January 1950 and July 2016. Seventeen publications were selected. Data analysis showed lower rates of mortality in the treatment group at 30 days ( P < 0.001), 180 days ( P = 0.001), 365 days ( P = 0.40), and overall ( P < 0.001). Pooling modified Rankin Scale and Glasgow outcome scale data, the treatment group had more good functional outcomes at 30 days ( P = 0.38), 90 days ( P = 0.04), 180 days ( P = 0.31), 365 days ( P = 0.76), and overall ( P = 0.02). Good functional outcome was defined as modified Rankin Scale score of 0 to 3 or a Glasgow outcome scale score of 3 to 5. Conclusions Intraventricular fibrinolytic for treatment of hypertensive intraventricular hemorrhage reduces mortality and potentially leads to an increased number of good functional outcomes. Different functional outcome scales (modified Rankin Scale or Glasgow outcome scale) produce different effect sizes. Intraventricular fibrinolytic treatment may offer intraventricular hemorrhage patients a targeted therapy that produces meaningful mortality benefit and possible functional outcome benefits.

Efficacy and safety of combined intraventricular fibrinolysis with lumbar drainage for prevention of permanent shunt dependency after intracerebral hemorrhage with severe ventricular involvement: A randomized trial and individual patient data meta-analysis. Ann Neurol 2017; 81:93-103. [PMID: 27888608 DOI: 10.1002/ana.24834] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2016] [Revised: 11/24/2016] [Accepted: 11/25/2016] [Indexed: 01/06/2023]
Abstract
OBJECTIVE Intraventricular hemorrhage (IVH) is a negative prognostic factor in intracerebral hemorrhage (ICH) and is associated with permanent shunt dependency in a substantial proportion of patients post-ICH. IVH treatment by intraventricular fibrinolysis (IVF) was recently linked to reduced mortality rates in the CLEAR III study and IVF represents a safe and effective strategy to hasten clot resolution that may reduce shunt rates. Additionally, promising results from observational studies reported reductions in shunt dependency for a combined treatment approach of IVF plus lumbar drains (LDs). The present randomized, controlled trial investigated efficacy and safety of a combined strategy-IVF plus LD versus IVF alone-on shunt dependency in patients with ICH and severe IVH. METHODS This randomized, open-label, parallel-group study included patients aged 18 to 85 years, prehospital modified Rankin Scale ≤3, ICH volume < 60ml, Glasgow Coma Scale of <9, and severe IVH with tamponade of the third and fourth ventricles requiring placement of external ventricular drainage (EVD). Over a 3-year recruitment period, patients were allocated to either standard treatment (control group receiving IVF consisting of 1mg of recombinant human tissue plasminogen activator every 8 hours until clot clearance of third and fourth ventricles) or a combined treatment approach of IVF and-upon clot clearance of third and fourth ventricles-subsequent placement of an LD for drainage of cerebrospinal fluid (CSF; intervention group). The primary endpoint consisted of permanent shunt placement indicated after a total of three unsuccessful EVD clamping attempts or need for CSF drainage longer than 14 days in both groups. Secondary endpoints included IVF- and LD-related safety, such as bleeding or infections, and functional outcome at 90 and 180 days. Conducted endpoint analyses used individual patient data meta-analyses. The study was registered at clinicaltrials.gov (NCT01041950). RESULTS The trial was stopped upon predefined interim analysis after 30 patients because of significant efficacy of tested intervention. The primary endpoint was analyzed without dropouts and was reached in 43% (7 of 16) of the control group versus 0% (0 of 14) of the intervention group (p = 0.007). Meta-analyses were based on overall 97 patients, 45 patients receiving IVF plus LD versus 42 with IVF only. Meta-analyses on shunt dependency showed an absolute risk reduction of 24% for the intervention (LD, 2.2% [1 of 45] vs no-LD, 26.2% [11 of 42]; odds ratio [OR] = 0.062; confidence interval [CI], 0.011-0.361; p = 0.002). Secondary endpoints did not show significant differences for CSF infections (OR = 0.869;CI, 0.445-1.695; p = 0.680) and functional outcome at 90 days (OR = 0.478; CI, 0.190-1.201; p = 0.116), yet bleeding complications were significantly reduced in favor of the intervention (OR = 0.401; CI, 0.302-0.532; p < 0.001). INTERPRETATION The present trial and individual patient data meta-analyses provide evidence that, in patients with severe IVH, as compared to IVF alone, a combined approach of IVF plus LD treatment is feasible and safe and significantly reduces rates of permanent shunt dependency for aresorptive hydrocephalus post-ICH.

Abstract
OBJECTIVE A voxel-based statistical approach on computer tomographic data in patients with intracerebral hemorrhage (ICH) and acute intraventricular hemorrhage (IVH) was used to evaluate spatial and temporal patterns of intraventricular blood in patients treated with intraventricular fibrinolysis (IVF) or without. METHODS IVH shapes were systematically assessed three dimensionally in patients with supratentorial ICH at three intervals of time (day of admission, day 4 ± 1, day 7+). The boundaries of the intraventricular blood clot were delineated on computed tomography (CT) scans using dedicated software. The CT scan and the IVH shape were transferred into stereotaxic space. In a second step, voxel-based statistics on group level were used to correlate the distribution of intraventricular blood with the interval and the treatment group. RESULTS Altogether 45 patients, 29 with IVF therapy and 16 without, were eligible to be included into this study. We found significant (false discovery rate [FDR] correction, q < .05) reduction of the intraventricular blood between day of admission and day 7 + for the third and fourth ventricle and parts of both lateral ventricles. In addition, we were able to show a significant difference between the IVF therapy and the conventionally treated group at day 4 ± 1 for the third ventricle. CONCLUSIONS The data indicate that voxel-based analysis on group level can be used to compare the time course and the distribution of intraventricular hemorrhage. This technique could be an interesting tool for future research on ICH with IVH.

Abstract
BACKGROUND Intraventricular fibrinolysis (IVF) in subarachnoid hemorrhage (SAH) is an emerging strategy aiming to hasten clot lysis, treat hydrocephalus, and reduce permanent shunt rates. Because of clinical heterogeneity of investigated patient effects of IVF on permanent shunt incidence and functional outcome are widely debated. The present study is the first to investigate solely endovascular-treated SAH patients. METHODS Overall, 88 consecutive patients with aneurysmal SAH requiring external ventricular drain placement and endovascular aneurysm closure were included. Functional outcome and shunt dependency were assessed 90 days after event. A matched controlled sub-analysis was carried out to investigate the effects of IVF treatment (n = 14; matching criteria: age, neuro-status and imaging). Multivariate modeling was performed to identify independent predictors for permanent shunt dependency. RESULTS In IVF-patients neurological status was significantly poorer [Hunt&Hess: IVF = 4(3-5) vs. non-IVF = 3(1-5); p = 0.035] and the extent of ventricular hemorrhage was increased [Graeb Score: IVF = 7(6-8) vs. non-IVF = 3(1-4); p ≤ 0.001]. Consecutive matched controlled sub-analysis revealed no significant therapeutic effect of IVF with respect to shunt dependency rate and functional outcome. Multivariate analysis revealed Graeb score [OR = 1.34(1.02-1.76); p = 0.035] and sepsis [OR = 11.23(2.28-55.27); p = 0.003] as independent predictors for shunt dependency, whereas IVF did not exert significant effects (p = 0.820). CONCLUSIONS In endovascular-treated SAH patients IVF neither reduced permanent shunt dependency nor influenced functional outcome. Despite established effects on intraventricular clot resolution IVF appears less powerful in SAH as compared to ICH. Given the reported positive effects of lumbar drainage (LD) in SAH, a prospective analysis of a combined treatment approach of IVF and subsequent lumbar drain sOeems warranted aiming to reduce permanent shunting and improve functional outcome.

Abstract
Optimal management of spontaneous intracerebral hemorrhage (ICH) remains one of the highly debated areas in the field of neurosurgery. Earlier studies comparing open surgical intervention with best medical management failed to show a clear benefit. More recent experience with minimally invasive techniques has shown greater promise. Well-designed phase II trials have confirmed the safety and preliminary treatment effect of thrombolytic aspiration and clearance of spontaneous ICH and associated intraventricular obstructive hemorrhage. Those trials are reviewed, including respective protocols and technical nuances, and lessons learned regarding patient selection, the concept of hemorrhage stabilization, optimization of the surgical procedure, and thrombolytic dosing decisions. These concepts have been incorporated in the design of ongoing definite phase III randomized trials (MISTIE and CLEAR) funded by the National Institutes of Health. These are presented including the role of surgical leadership in the training and monitoring of the surgical task and quality assurance. The impact of these techniques on neurosurgical practice is discussed.

Abstract
INTRODUCTION In severe spontaneous intraventricular hemorrhage (IVH), intraventricular (IVR) administration of tissue plasminogen activator (rtPA) clears blood from the ventricles more rapidly than with external ventricular drainage (EVD) alone. However, experimental studies suggest tPA may be neurotoxic in compromised brain tissue and may exacerbate perihematomal edema. METHODS We used computerized volumetrics to assess change in intracerebral hemorrhage (ICH), IVH, ventricular, and perihematomal edema (PHE) volumes at 2-4 (T1) and 5-9 (T2) days following diagnostic CT scans (T0) of 24 patients (12 tPA-treated; 12 controls) with IVH requiring EVD. Controls from a hospital registry were matched by IVH and ICH volume to tPA-treated patients who came from a multicenter trial involving 52 patients with IVH. RESULTS There were no significant differences between matched pairs in admission ICH and IVH volumes. IVR tPA resulted in more rapid clearance of IVH as determined by T2-T0 decrease in median IVH volume (tPA: -18.7 cc, iqr 14.9; control:-6.9 cc, iqr 6.4; P = 0.002). Median ratios of PHE to ICH volume were not significantly different in control versus tPA-treated patients at T1 and T2 [control:tPA = 0.55:0.56 (T1); P = 0.84 and 0.81:0.71 (T2); P = 1.00]. Total ventricular volume was significantly larger in the control group at T2 (mean: 57.57 ± 10.32 vs. tPA: 24.80 ± 2.67 cc; P = 0.01). Bacterial ventriculitis was more frequent in the control group (5 vs. 1 episodes; P = 0.06) as was shunt dependence (4 vs. 0 cases; P = 0.03). CONCLUSIONS For case matched large IVH with small ICH volume, IVR tPA enhances lysis of intraventricular blood clots and has no significant impact on PHE.

Abstract
PURPOSE OF REVIEW Bloody cerebrospinal fluid (CSF) is a major cause of morbidity and mortality in intraventricular hemorrhage (IVH) and subarachnoid hemorrhage (SAH). Different treatment strategies aiming at faster clearance of bloody CSF have emerged. The present review focuses on recent developments in the investigation of those treatments. RECENT FINDINGS Intraventricular fibrinolysis (IVF) for accelerated IVH-resolution has been clinically tested since the early 1990s. The lately summarized evidence from smaller studies indicates that IVF may result in a benefit in mortality and outcome. Recent investigations have elucidated different aspects of IVF, mainly related to safety. Neuroendoscopy has also emerged as a minimally invasive technique allowing fast removal of IVH. The capability of lumbar drainage to reduce vasospasm after SAH has been tested in a large trial. SUMMARY IVF is relatively well tolerated and accelerates clot clearance after IVH. The effect of IVF on clinical outcome and mortality is currently being investigated in a large-scale phase III clinical trial. Neuroendoscopy is feasible for the treatment of IVH, however, larger trials are lacking. Lumbar drainage reduces the incidence of vasospasm after SAH. An ongoing phase III trial has been designed to test its influence on outcome. Lumbar drainage may also reduce shunt-dependency after IVH.

Abstract
BACKGROUND In adults, intraventricular thrombolytic therapy with recombinant tissue plasminogen activator (rtPA) facilitates resolution of intraventricular haemorrhage (IVH), reduces intracranial pressure, decreases duration of cerebrospinal fluid diversion, and may ameliorate direct neural injury. We hypothesize that patients with small parenchymal haematoma volumes (<30 cc) and relatively large IVH causing acute obstructive hydrocephalus would have improved clinical outcomes when given injections of low-dose rtPA to accelerate lysis and evacuation of IVH compared with placebo. METHODS The Clot Lysis Evaluation of Accelerated Resolution of Intraventricular Hemorrhage III trial is an investigator-initiated, phase III, randomized, multicenter, double-blind, placebo-controlled study comparing the use of external ventricular drainage (EVD) combined with intraventricular injection of rtPA to EVD plus intraventricular injection of normal saline (placebo) for the treatment of IVH. Patients with known symptom onset within 24 h of the computed tomography scan confirmed IVH and third or fourth ventricle obstruction, with or without supratentorial intracerebral haemorrhage volume <30 cc, who require EVD are screened with a computed tomography scan at least six hours after EVD placement and, if necessary, at consecutive 12-h intervals until stabilization of any intracranial bleeding has been established. Patients who meet clinical and imaging criteria (no ongoing coagulopathy and no suspicion of aneurysm, arteriovenous malformation, or any other vascular anomaly) will be randomized to either intraventricular rtPA or placebo. RESULTS The primary outcome measure is dichotomized modified Rankin Scale 0-3 vs. 4-6 at 180 days. Clinical secondary outcomes include additional modified Rankin Scale dichotomizations at 180 days (0-4 vs. 5-6), ordinal modified Rankin Scale (0-6), mortality and safety events at 30 days, mortality at 180 days, functional status measures, type and intensity of intensive care unit management, rate and extent of ventricular blood clot removal, and quality of life measures.

Abstract
Intracranial hemorrhage (ICH) accounts for 10-15 % of all strokes, however it causes 30-50 % of stroke related mortality, disability and cost. The prevalence increases with age with only two cases/100,000/year for age less than 40 years to almost 350 cases/100,000/year for age more than 80 years. Several trials of open surgical evacuation of ICH have failed to show clear benefit over medical management. However, some small trials of minimal invasive hematoma evacuation in combination with thrombolytics have shown encouraging results. Based on these findings larger clinical trials are being undertaken to optimize and define therapeutic benefit of minimally invasive surgery in combination with thrombolytic clearance of hematoma. In this article we will review some of the background of minimally invasive surgery and the use of thrombolytics in the setting of ICH and intraventricular hemorrhage (IVH) and will highlight the early findings of MISTIE and CLEAR trials for these two entities respectively.

Abstract
OBJECT Massive intraventricular hemorrhages (IVHs) require aggressive and rapid management to decrease intracranial hypertension, because the amount of intraventricular blood is a strong negative prognostic predictor on outcome. Neuroendoscopy may offer some advantages over more traditional surgical approaches on outcome and may decrease the number of shunt procedures that need to be performed. METHODS The authors retrospectively reviewed the clinical and radiological data in 96 patients treated for massive IVH who were admitted between January 1996 and June 2008 to the neurosurgery unit after undergoing emergency CT scanning. Forty-eight patients (Group A) were treated with endoscopic aspiration surgery using a flexible endoscope with a "freehand" technique. A historical group of 48 patients (Group B) treated using external ventricular drain (EVD) placement alone was used as a comparison. The authors compared the radiological results with the clinical outcomes at 1 year according to the modified Rankin Scale and the need for internal CSF shunt treatment in the 2 groups. RESULTS Endoscopic aspiration did not significantly affect the outcome at 1 year as determined using the modified Rankin Scale. Patients who underwent endoscopy had an EVD in place for 0.18 days fewer than patients treated with an EVD alone. Patients undergoing external ventricular drainage alone had a 5 times greater chance of requiring a shunting procedure than those treated using neuroendoscopy and external ventricular drainage. Neuroendoscopy plus external drainage reduces shunting rates by 34% when compared with external drainage alone. CONCLUSIONS The reduction in internal shunt surgery encourages the adoption of neuroendoscopic aspiration of severe IVH as a therapeutic tool to decrease shunt dependency.

Abstract
Hemorrhagic stroke accounts for only 10% to 15% of all strokes; however, it is associated with devastating outcomes. Extension of intracranial hemorrhage (ICH) into the ventricles or intraventricular hemorrhage (IVH) has been consistently demonstrated as an independent predictor of poor outcome. In most circumstances the increased intracranial pressure and acute hydrocephalus caused by ICH is managed by placement of an external ventricular drain (EVD). We present a systematic review of the literature on the topic of EVD in the setting of IVH hemorrhage, articulating the scope of the problem and prognostic factors, clinical indications, surgical adjuncts, and other management issues.

Abstract
The presence of additional intraventricular hemorrhage (IVH) in patients with intracerebral hemorrhage (ICH) is associated with a much higher mortality and worse functional outcome. Although evidence-based specific treatment options for this entity are still lacking, knowledge about the pathophysiology of IVH has grown in recent decades, leading to the development of promising treatment strategies. Intraventricular fibrinolysis (IVF) accelerates IVH resolution and removal from the ventricular system. The additional usage of lumbar drains probably reduces the incidence of permanent posthemorrhagic hydrocephalus. The influence of these treatment modalities on functional outcome is currently being investigated in ongoing studies. The present article gives an overview of pathophysiological and clinical aspects of IVH, emphasizing novel treatment options.

Abstract
OBJECTIVES Massive intracerebral and intraventricular hemorrhages require aggressive and rapid management to decrease intracranial hypertension. The amount of intraventricular blood is a strong prognostic predictor, and its fast removal is a priority. Neuroendoscopy may offer some advantages over more traditional surgical approaches. METHODS All relevant data described in our experience and in publications about minimally invasive treatment of intraventricular and intracerebral hemorrhage found through MEDLINE searches and related references are reviewed. RESULTS We described the technical details of neuroendoscopic management, highlighting the potential pitfalls and advantages of the techniques. CONCLUSION Early neuroendoscopic surgery is a feasible approach, allowing, in most instances, rapid clinical and radiological improvement.

Abstract
Intracerebral haemorrhage (ICH) is the most devastating type of stroke and is a leading cause of disability and mortality. By contrast with advances in ischaemic stroke treatment, few evidence-based targeted treatments exist for ICH. Management of ICH is largely supportive, with strategies aimed at the limitation of further brain injury and the prevention of associated complications, which add further detrimental effects to an already lethal disease and jeopardise clinical outcomes. Complications of ICH include haematoma expansion, perihaematomal oedema with increased intracranial pressure, intraventricular extension of haemorrhage with hydrocephalus, seizures, venous thrombotic events, hyperglycaemia, increased blood pressure, fever, and infections. In view of the restricted number of therapeutic options for patients with ICH, improved surveillance is needed for the prevention of these complications, or, when this is not possible, early detection and optimum management, which could be effective in the reduction of adverse effects early in the course of stroke and in the improvement of prognosis. Further studies are needed to enhance the evidence-based recommendations for the management of this important clinical problem.

Abstract
Intraventricular hemorrhage (IVH) has been associated with poor prognosis in patients with spontaneous intracerebral hemorrhage. Several factors contribute to the deleterious effects of IVH, including direct mass effects of the ventricular blood clot on ependymal and subependymal brain structures, mechanical and inflammatory impairment of the Pacchioni granulations by blood and its breakdown products, and disturbance of physiological cerebrospinal fluid (CSF) circulation. Acute obstructive hydrocephalus represents a major life-threatening complication of IVH and is usually treated with an external ventricular drainage (EVD). However, treatment with EVD alone is frequently not sufficiently effective due to obstruction of the catheter by blood. In the past two decades, intraventricular fibrinolysis (IVF) has been increasingly used for maintenance of EVD functionality and acceleration of ventricular clot resolution in such patients. Unfortunately, there is no prospective, randomized controlled trial addressing the effect of IVF on clinical outcome. The available data on IVF consist of small retrospective case series, case reports, and a few prospective case-control studies, which are the subject of the present review article. All these studies, when considered in their entirety, suggest that IVF has a positive impact on mortality and functional outcome, and could be considered as a treatment option for selected patients.

Abstract
OBJECTIVES To evaluate safety, clinical feasibility, and outcome of intraventricular (IVen) administration of recombinant tissue plasminogen activator (rt-PA) in patients with intraventricular hemorrhage (IVH). MATERIALS AND METHODS Forty-eight patients with IVH who received IVen rt-PA were compared with 49 age-, sex-, Glasgow Coma Scale score-, and Intracerebral Hemorrhage score-matched control patients. Patients with IVH of aneurysmal or arteriovenous malformation origin were excluded. External ventricular drainage was inserted as soon as baseline CT was performed and rt-PA was administered within 12 ± 1 h after the ictal onset. RESULTS The outcome after 3 months was evaluated using the modified Rankin Scale (mRS). In addition, Glasgow Outcome Scale (GOS) and mortality were assessed. A good outcome, defined as mRS 0-3, was detected in 27% of patients from the control group vs 58% of patients in the IVen group; P = 0.003. GOS as other outcome scale yielded a significant difference between groups: 20% in the control group, vs 54% in the IVen group; P = 0.001. A statistically significant decrease in mortality was observed in the IVen group: 30% in the control vs 10% in IVen group; P = 0.003. No one patient died because of a complication which could be directly attributed to the IVen thrombolytic therapy. CONCLUSIONS IVen administration of rt-PA seems to be safe in cases of IVH. This pilot study shows that it may be associated with better outcomes. Further studies and clinical randomized trials are needed to establish indications and IVen administration protocols.

Abstract
Intracerebral hemorrhage (ICH) remains a common and deadly form of stroke, with virtually no greatly effective treatments aside from supportive and stroke unit care. Several surgical and medical therapies have been studied, but nothing has yet been found that greatly changes the pathophysiology. To achieve this, there will need to be substantial changes in treatment strategies. This article will focus on refinements to existing strategies and consider new approaches to the management of ICH. It will draw parallels with ischemic stroke treatments, and define the idea of ‘interventional therapy’ for ICH. It is suggested that reducing hematoma expansion could be compared with salvage of the ischemic penumbra, as a potential target for interventional ICH treatments. The concept of different time windows for the application of therapies according to the pathophysiology will be discussed. Finally, some novel treatment strategies are proposed, including an endovascular approach and ‘external, stereotactic cautery’, as future possibilities.

Abstract
BACKGROUND AND PURPOSE The purpose of this study was to analyze the effect of intraventricular fibrinolysis (IVF) compared with external ventricular drainage alone on mortality and functional outcome in the management of intraventricular hemorrhage secondary to spontaneous supratentorial intracerebral hemorrhage. METHODS The authors conducted a systematic review and performed a meta-analysis. They reviewed the PubMed, Cochrane Library, and Liliacs databases. In addition, they conducted a manual review of article bibliographies. RESULTS Using a prespecified search strategy, 4 randomized and 8 observational studies were included in a meta-analysis. These studies involved a total of 316 patients with intraventricular hemorrhage at baseline, of whom 167 had IVF (52.8%). Pooled odds ratios of the impact of IVF on patient mortality, functional outcomes, and complications were calculated. The overall mortality risk decreased from 46.7% in the external ventricular drainage alone group to 22.7% in the external ventricular drainage+IVF group, corresponding to an overall pooled Peto OR of 0.32 (95% CI, 0.19 to 0.52). This result was highly significant with urokinase, not with recombinant tissue-type plasminogen activator. IVF was also associated with an increase in good functional outcome. There was no difference between the 2 groups in terms of shunt dependence and complications. CONCLUSIONS The combination of IVF and external ventricular drainage in the management of severe intraventricular hemorrhage secondary to small intracerebral hemorrhage in young patients was associated with better survival and functional outcome results. Urokinase and recombinant tissue-type plasminogen activator could not have the same therapeutic effects. Well-designed randomized trials with special considerations to the fibrinolytic agents are needed.

Abstract
Intracerebral haemorrhage is the most devastating subtype of stroke. It affects approximately two million patients worldwide every year and is a major cause of morbidity and mortality. After decades of research, we still face the fact that there is no evidence-based treatment strategy for this disease. However, research has contributed to a better understanding of the pathophysiology of intracerebral haemorrhage and also to the identification of new treatment targets. Several novel aspects of treatment of spontaneous intracerebral haemorrhage are reviewed in the present article.

Abstract
Controversy still exists on surgical management of acute stroke. Even if surgical therapy represents often a life-saving measure, the issue of acceptable outcome remains open. Persuasive evidence for outcome benefit is limited. For large ischaemic strokes, recent convincing data suggest that decompressive surgery significantly reduces mortality and improves outcome quality. On the other hand, despite the long tradition in surgical removal of intracranial haematomas, the recent evidence has not been sufficient to resolve the basic argument whether to operate or not. Most recently, hopeful preliminary data have emerged on new approaches in the treatment of intraventricular haemorrhage. In this article, we review the current neurosurgical options in acute ischaemic and haemorrhagic stroke.

Abstract
Introduction There are only limited data on the long-term outcome of patients receiving specialized neurocritical care. In this study we analyzed survival, long-term mortality and functional outcome after neurocritical care and determined predictors for good functional outcome. Methods We retrospectively investigated 796 consecutive patients admitted to a non-surgical neurologic intensive care unit over a period of two years (2006 and 2007). Demographic and clinical parameters were analyzed. Depending on the diagnosis, we grouped patients according to their diseases (cerebral ischemia, intracranial hemorrhage (ICH), subarachnoid hemorrhage (SAH), meningitis/encephalitis, epilepsy, Guillain-Barré syndrome (GBS) and myasthenia gravis (MG), neurodegenerative diseases and encephalopathy, cerebral neoplasm and intoxication). Clinical parameters, mortality and functional outcome of all treated patients were analyzed. Functional outcome (using the modified Rankin Scale, mRS) one year after discharge was assessed by a mailed questionnaire or telephone interview. Outcome was dichotomized into good (mRS ≤ 2) and poor (mRS ≥ 3). Logistic regression analyses were calculated to determine independent predictors for good functional outcome. Results Overall in-hospital mortality amounted to 22.5% of all patients, and a good long-term functional outcome was achieved in 28.4%. The parameters age, length of ventilation (LOV), admission diagnosis of ICH, GBS/MG, and inoperable cerebral neoplasm as well as Therapeutic Intervention Scoring System (TISS)-28 on Day 1 were independently associated with functional outcome after one year. Conclusions This investigation revealed that age, LOV and TISS-28 on Day 1 were strongly predictive for the outcome. The diagnoses of hemorrhagic stroke and cerebral neoplasm leading to neurocritical care predispose for functional dependence or death, whereas patients with GBS and MG are more likely to recover after neurocritical care.

Abstract
BACKGROUND AND PURPOSE Both intraventricular fibrinolysis (IVF) and lumbar drainage (LD) may reduce the need for exchange of external ventricular drainage (EVD) and shunt surgery in patients with intracerebral hemorrhage and severe intraventricular hemorrhage. We investigated the feasibility and safety of IVF followed by early LD for the treatment of posthemorrhagic hydrocephalus. METHODS This prospective study included patients with spontaneous ganglionic intracerebral hemorrhage and severe intraventricular hemorrhage with acute obstructive posthemorrhagic hydrocephalus who received an EVD (n=32). The treatment algorithm started with IVF (4 mg recombinant tissue plasminogen activator every 12 hours) until clearance of the third and fourth ventricles from blood. Thereupon, EVD was clamped and if clamping was unsuccessful, communicating posthemorrhagic hydrocephalus was assumed and LD placed. EVD was removed if there was neither an increase of intracranial pressure nor ventricle enlargement on CT. A ventriculoperitoneal shunt was indicated if "LD weaning" was unsuccessful for >10 days. Outcome was assessed at 90 and 180 days using the modified Rankin Scale. RESULTS IVF resulted in fast clearance of the third and fourth ventricles (73+/-50 hours). However, early EVD removal was only possible in 4 patients. The remaining 28 patients developed communicating posthemorrhagic hydrocephalus. In all of these patients, early LD was capable to replace EVD. EVD exchange was not necessary and EVD duration was 105+/-59 hours. Only one patient required a ventriculoperitoneal shunt. At 180 days, 20 (62.5%) patients had a good (modified Rankin Scale 0 to 3) outcome and 5 (15.6%) patients had died. One patient had asymptomatic ventricular rebleeding. CONCLUSIONS In patients with secondary intraventricular hemorrhage and posthemorrhagic hydrocephalus, the combined treatment approach of IVF and early LD is safe and feasible, avoids EVD exchange, and may markedly reduce the need for shunt surgery.

Abstract
Intracerebral haemorrhage is an important public health problem leading to high rates of death and disability in adults. Although the number of hospital admissions for intracerebral haemorrhage has increased worldwide in the past 10 years, mortality has not fallen. Results of clinical trials and observational studies suggest that coordinated primary and specialty care is associated with lower mortality than is typical community practice. Development of treatment goals for critical care, and new sequences of care and specialty practice can improve outcome after intracerebral haemorrhage. Specific treatment approaches include early diagnosis and haemostasis, aggressive management of blood pressure, open surgical and minimally invasive surgical techniques to remove clot, techniques to remove intraventricular blood, and management of intracranial pressure. These approaches improve clinical management of patients with intracerebral haemorrhage and promise to reduce mortality and increase functional survival.

Abstract
OBJECTIVE To review the literature concerning intraventricular administration of fibrinolytic agents to treat patients with intraventricular hemorrhage (IVH). DATA SOURCES An extensive literature search (MEDLINE, EMBASE, Conference Proceedings) was conducted to identify articles in English published between 1966 and May 2000 pertaining to the pathophysiology of IVH and its treatment by intraventricular administration of recombinant tissue plasminogen activator (alteplase) or urokinase (u-PA). The bibliographies of selected identified articles were also screened for publications not found in the computerized search. STUDY SELECTION All pertinent publications were reviewed and considered. Those describing the intraventricular administration of fibrinolytic agents to patients with IVH were included. DATA SYNTHESIS IVH has a poor prognosis, partly due to the mass effect of blood clots on the ventricular walls. The cerebrospinal fluid has a limited fibrinolytic system. Therefore, clots may remain in the ventricles for months after a hemorrhage. The management of IVH is primarily directed at controlling intracranial pressure through an external ventricular drain, but this catheter often becomes occluded by coagulated blood. To overcome this problem, and to dissolve the residual blood clot, investigators have administered alteplase or u-PA directly into the ventricles of patients with IVH. Complications of this therapy include infection and possible rebleeding. Clinical studies of fibrinolytic therapy for IVH have found a 30-35% reduction in mortality with treatment, but to date, have not clearly documented improved neurologic outcome of the survivors. CONCLUSIONS Fibrinolytic therapy with alteplase or u-PA may be life-saving in severe cases of IVH. Yet many technical issues remain to be resolved, such as the optimal dose, frequency, method, timing, and duration of administration of the agent. Additional randomized, double-blind, placebo-controlled studies need to be performed so that the true value of this therapy can be assessed.
