Abstract
Background The effect of Ommaya reservoirs on the clinical outcomes of patients with intraventricular hemorrhage (IVH) remains unclear. Objective We aimed to determine the effect of combining the Ommaya reservoir and external ventricular drainage (EVD) therapy on IVH and explore better clinical indicators for Ommaya implantation. Methods A retrospective analysis was conducted on patients diagnosed with IVH who received EVD-Ommaya drainage between January 2013 and March 2021. The patient population was divided into two groups: the Ommaya-used group, comprising patients in whom the Ommaya drainage system was activated post-surgery, and the Ommaya-unused group, comprising patients in whom the system was not activated. The study analyzed clinical, imaging, and outcome data of the patient population. Results A total of 123 patients with IVH were included: 75 patients in the Ommaya-used group and 48 patients in the Ommaya-unused group. The patients in the Ommaya-used group showed a lower 3-month GOS than those in the Ommaya-unused group (p<0.0001). The modified Graeb scale (mGS) in the Ommaya-unused group was significantly lower than that in the Ommaya-used group before the operation (p<0.01) but not after surgery (p>0.05). The GCS in the Ommaya-unused group was significantly lower than that in the other group, and there was a close correlation between the GCS and 3-month GOS (p<0.0001). The GCS score showed significance in predicting the use of Ommaya (p<0.001). Conclusion The study demonstrated that combining EVD and Ommaya drainage was a safe and feasible treatment for IVH. Additionally, preoperative GCS was found to predict the use of Ommaya drainage in subsequent treatment, providing valuable information for pre-surgery decision-making.

Abstract
Intraventricular hemorrhage (IVH) is a clinical challenge observed among 40-45% of intracerebral hemorrhage (ICH) cases. IVH can be classified according to the source of the hemorrhage into primary and secondary IVH. Primary intraventricular hemorrhage (PIVH), unlike secondary IVH, involves only the ventricles with no hemorrhagic parenchymal source. Several risk factors of PIVH were reported which include hypertension, smoking, age, and excessive alcohol consumption. IVH is associated with high mortality and morbidity and several prognostic factors were identified such as IVH volume, number of ventricles with blood, involvement of fourth ventricle, baseline Glasgow Coma Scale score, and hydrocephalus. Prompt management of patients with IVH is required to stabilize the clinical status of patients upon admission. Nevertheless, further advanced management is crucial to reduce the morbidity and mortality associated with intraventricular bleeding. Recent treatments showed promising outcomes in the management of IVH patients such as intraventricular anti-inflammatory drugs, lumbar drainage, and endoscopic evacuation of IVH, however, their safety and efficacy are still in question. This literature review presents the epidemiology, physiopathology, risk factors, and outcomes of IVH in adults with an emphasis on recent treatment options.

Abstract
BACKGROUND Intraventricular hemorrhage (IVH) is a severe and devastating stroke. Research on existing treatment options has been controversial. Therefore, we aimed to evaluate the safety and efficacy of minimally implanted stereotactic puncture combined with urokinase (uPA) in the treatment of IVH. METHODS The clinical data of 122 IVH patients admitted to our department from 2018 to 2022 were retrospectively analyzed. According to the modified RanKin score (mRS) after 30 days, the patients were divided into good prognosis (mRS 0-3) and poor prognosis (mRS 4-6), and the factors affecting the prognosis were screened by univariate and multivariate analysis, and then the tendency Score matching and paired patient screening were performed for comparative analysis between uPA and non-uPA groups. RESULTS Patients' age, uPA usage, initial Glasgow Coma Scale and primary blood volume all could affect the mRS score of patients. One hundred patients were finally included, including 50 cases in the uPA group and 50 cases in the non-uPA group. The analysis showed that at follow-up after 30 days, 46.0% of the patients in the uPA group and 28.0% in the non-uPA group had an mRS score of 0-3; however, they were not statistically significantly different. The postoperative hematoma clearance rate in the uPA group was significantly higher than that in the non-uPA group (P < 0.001), and the incidence of postoperative complications was not increased (P > 0.05). CONCIUSIONS uPA treatment can improve the treatment efficiency. However, its effect in improving patient outcomes does not appear to be significant.

Abstract
BACKGROUND Intraventricular fibrinolysis (IVF) and endoscopic surgery (ES) are the new promising treatment strategies to enhance the rate of hematoma clearance, which might improve functional outcome. This study investigated and compared the outcomes among these interventions. METHODS A randomized (1:1) double-blinded trial was carried out between August 2018 and December 2021. The intervention and control groups comprised patients receiving IVF and/or ES and external ventricular drainage (EVD), respectively. All participants had experienced primary or secondary intraventricular hemorrhage (IVH) from spontaneous intracerebral hemorrhage with obstructive hydrocephalus complications. The primary outcome was modified Rankin Scale score 180 days post treatment. Interim assessments were planned for every 50 participants enrolled to ensure safety and efficacy. RESULTS After enrollment of 110 participants (55 participants in each group), there was a difference in 30-day mortality (2 [3.6%] vs. 13 [32.7%] in the EVD group, P = 0.002), reaching the predetermined boundaries for termination of the trial. We demonstrated a better favorable outcome (modified Rankin Scale score 0-3) at 180 days in the intervention group, compared with the control group (35 [63.6%] vs. 24 [43.6%], P = 0.04). Participants in the intervention group experienced a higher IVH removal rate (91% [9.0] vs. 69.5% [38.0], P < 0.01) and had lower shunt conversion (1 [1.8%] vs. 16 [29.3%], P < 0.01). Treatment complications were comparable between the two groups. CONCLUSIONS This study demonstrated that combined ES and IVF is safe and effective for the treatment of IVH. In addition, it concluded that aggressive but safe procedures used to remove IVH could improve clinical outcome in patients with IVH.

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.

Historical aspects of the problem of surgical treatment of hemorrhagic stroke. The role of intracranial pressure in the choice of treatment tactics (review of literature). ACTA BIOMEDICA SCIENTIFICA 2021.

Abstract
This article provides a literature review of the past 60 years, conducted using keywords through the PubMed Internet resource, dedicated to the methods of surgical treatment of hemorrhagic stroke. The existing published results of clinical studies do not allow us to draw unambiguous conclusions about the superiority of conservative or neurosurgical treatment in relation to the functional recovery of patients. There is a statistical significance of the advantages of surgery based on the prevention of dislocation syndrome, control of intracranial hypertension, and prevention or at least reduction of the effect of blood and its degradation products on the surrounding healthy tissue. However, large randomized controlled trials have failed to demonstrate this benefit in terms of mortality or functional outcome.There are two main areas of hemorrhagic stroke surgery – open surgery and minimally invasive methods. The practice of open surgery is associated with high trauma rates, as well as with certain risks and complications. However, craniotomy is a lifesaving measure in critical situations with signs of persistent increased intracranial pressure leading to neurological impairment. The ability to control intracranial pressure provides a chance for the choice of more optimal tactics of surgical treatment.Today, the gold standard for intracranial pressure monitoring is the installation of invasive intraventricular or intraparenchymal transducers. The method is appreciated for its accuracy, however, there are a number of disadvantages in the form of the possibility of hemorrhagic and infectious complications, as well as the high cost of the sensor itself, which limits its routine use. The inability to measure intracranial pressure before surgery causes an unreasonable expansion of indications for choosing an open method of surgery, which reduces the possibility of a better functional outcome.All of these points make it urgent to search for a non-invasive method for measuring intracranial pressure, which would contribute to the timely choice of a surgical method without the danger of worsening the clinical outcome.

Abstract
OBJECTIVE This study discusses the therapeutic effect of high-dose urokinase treatment for hypertension ventricular hemorrhage. METHODS A total of 60 patients with hypertension ventricular hemorrhage were randomly assigned to two groups: treatment group (n=30) and control group (n=30). Both groups received bilateral external ventricular drain. The treatment group was injected with 50,000IU urokinase to the lateral ventricle every day; the total injection volume per day was 100,000IU. The control group was injected with 20,000IU urokinase to the lateral ventricle every day with a total injection volume per day of 40,000IU. Lumbar puncture was performed in both groups after the later ventricular drain was removed to release cerebrospinal fluid (CSF). Head Computed tomography(CT) examination was performed regularly to observe changes in the ventricular hematoma as well as the occurrence of complications such as intracranial infection and hydrocephalus. Patient prognosis 6 weeks after surgery was compared between the two groups. RESULTS In the treatment group, the intraventricular hemorrhage clearance time and the number of instances of urokinase treatment were significantly less than those of the control group (P<0.05). The total urokinase dosage of the treatment group was significantly higher than that of the control group (P<0.05). With respect to post-surgery complications, in the treatment group, there were three cases of hydrocephalus and one case of intracranial infection. In the control group, there were four cases of hydrocephalus and three cases of intracranial infection. Intraventricular re-hemorrhage was not observed in either group. Intracranial infection was relieved after strengthened anti-infective therapy and continuous drainage. There was a statistically significant difference in the occurrence of complications between the treatment group and the control group (P<0.05). The rate of good prognosis in the treatment group was higher than that of the control group (P<0.05), and the inefficiency rate was lower (P<0.05). CONCLUSIONS High-dose urokinase treatment produces a significant therapeutic effect in hypertension ventricular hemorrhage. This treatment can quickly eliminate intraventricular hemorrhage, shorten the ventricular drain tube indwelling time, decrease the occurrence of intracranial infection, and increase the likelihood of a good prognosis.

Abstract
Objective Rapid dissolution of blood clots reduces vasospasm and hydrocephalus after subarachnoid hemorrhage (SAH), and locally administered fibrinolytic drugs (LAFDs) could facilitate the dissolution. However, the efficacy of LAFDs remains controversial. The aim of this meta-analysis was to determine the efficacy of LAFDs for vasospasm and hydrocephalus and in clinical outcomes.
Methods From PubMed, EMBASE, and Cochrane database, data were extracted by two authors. Meta-analysis was performed using a random effect model. Inclusion criteria were patients who had LAFDs with urokinase-type or recombinant tissue-plasminogen activator after SAH in comparison with medically untreated patients with fibrinolytic drugs. We only included randomized controlled trials (RCTs) in this analysis. The outcomes of interest were vasospasm, hydrocephalus, mortality, and 90-day unfavorable functional outcome.
Results Data from eight RCTs with 550 patients were included. Pooled-analysis revealed that the LAFDs were significantly associated with lower rates of vasospasm (LAFDs group vs. control group, 26.5% vs. 39.2%; odds ratio [OR], 0.48; 95% confidence interval [CI], 0.32–0.73); hydrocephalus (LAFDs group vs. control group, 26.0% vs. 31.6%; OR, 0.54; 95% CI, 0.32–0.91); and mortality (LAFDs group vs. control group, 10.5% vs. 15.7%; OR, 0.58; 95% CI, 0.34–0.99). The proportion of 90-day unfavorable outcomes was lower in the LAFDs group (LAFDs group vs. control group, 32.7% vs. 43.5%; OR, 0.55; 95% CI, 0.37–0.80).
Conclusion This meta-analysis with eight RCTs indicated that LAFDs were significantly associated with lower rates of vasospasm and hydrocephalus after SAH. Thus, LAFDs could consequently reduce mortality and improve clinical outcome after SAH.

Abstract
BACKGROUND This study aimed to compare the characteristics of patients with spontaneous thalamic hemorrhage (STH) accompanied by intraventricular hemorrhage (IVH) with those of patients without IVH. METHODS The medical records of consecutive patients with STH admitted to our institute between January 2000 and December 2018 were reviewed retrospectively. The laboratory and radiological results, mortality, and functional recovery were compared between the STH patients with IVH and those without IVH. RESULTS Among 2,389 patients with spontaneous intracerebral hemorrhage, 233 (9.8%) patients were included in this study. Concurrent IVH was detected in 159 (68.2%) patients with STH, and more frequently in those with body mass index ≥ 25, Glasgow Coma Scale score of 3-8, underlying disease, family history of stoke, posterior/medial/global location of hematoma, ventriculomegaly, large volume of hemorrhage, and midline shift ≥ 5 mm. The 3-month mortality was 25.8% and 8.1% (P = 0.039), the rate of good functional recovery at 6 months was 52.2% and 31.0% (P = 0.040), and incidence of delayed normal pressure hydrocephalus (NPH) at 12 months was 10.8% and 24.5% (P = 0.062) in the STH patients with IVH and those without IVH, respectively. At 12 months, delayed NPH developed in 28 of 47 (59.6%) patients who received external ventricular drainage (EVD)-based treatment, 5 of 45 (11.1%) patients who underwent endoscopic evacuation-based treatment, and 8 of 45 (17.8%) patients who underwent other surgeries. CONCLUSION Concurrent IVH is strongly associated with mortality in patients with STH. Delayed NPH may develop more frequently in STH patients with IVH who were treated with EVD.

Evaluation of Volumetric Change of Intracerebral Hemorrhage in Patients Treated with Thrombolysis for Intraventricular Hemorrhage. Neurocrit Care 2020; 34:529-536. [PMID: 32737761 PMCID: PMC8128818 DOI: 10.1007/s12028-020-01054-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2020] [Accepted: 07/09/2020] [Indexed: 11/19/2022]
Abstract
Background Intraventricular hemorrhage (IVH) is often caused by irruption of intracerebral hemorrhage (ICH) of basal ganglia or thalamus into the ventricular system. Instillation of recombinant tissue plasminogen activator (rtPA) via an external ventricular drainage (EVD) has been shown to effectively decrease IVH volumes while the impact of rtPA instillation on ICH volumes remains unclear. In this series, we analyzed volumetric changes of ICH in patients with and without intrathecal lysis therapy. Methods Between 01/2013 and 01/2019, 36 patients with IVH caused by hemorrhage of basal ganglia, thalamus or brain stem were treated with rtPA via an EVD (Group A). Initial volumes were determined in the first available computed tomography (CT) scan, final volumes in the last CT scan before discharge. During the same period, 41 patients with ICH without relevant IVH were treated without intrathecal lysis therapy at our neurocritical care unit (Group B). Serial CT scans were evaluated separately for changes in ICH volumes for both cohorts using OsiriX DICOM viewer. The Wilcoxon signed-rank test was performed for statistical analysis in not normally distributed variables. Results Median initial volume of ICH for treatment Group A was 6.5 ml and was reduced to 5.0 ml after first instillation of rtPA (p < 0.01). Twenty-six patients received a second treatment with rtPA (ICH volume reduction 4.5 to 3.3 ml, p < 0.01) and of this cohort further 16 patients underwent a third treatment (ICH volume reduction 3.0 ml to 1.5 ml, p < 0.01). Comparison of first and last CT scan in Group A confirmed an overall median percentage reduction of 91.7% (n = 36, p < 0.01) of ICH volumes and hematoma resolution in Group A was significantly more effective compared to non-rtPA group, Group B (percentage reduction = 68%) independent of initial hematoma volume in the regression analysis (p = 0.07, mean 11.1, 95%CI 7.7–14.5). There were no adverse events in Group A related to rtPA instillation. Conclusion Intrathecal lysis therapy leads to a significant reduction in the intraparenchymal hematoma volume with faster clot resolution compared to the spontaneous hematoma resorption. Furthermore, intrathecal rtPA application had no adverse effect on ICH volume.

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
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
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.

Endoscope-assisted microsurgical evacuation versus external ventricular drainage for the treatment of cast intraventricular hemorrhage: results of a comparative series. Neurosurg Rev 2019; 43:695-708.

Abstract
Cast intraventricular hemorrhage (IVH) is associated to high morbidity/mortality rates. External ventricular drainage (EVD), the most common treatment adopted in these patients, may be unsuccessful due to short-term drain obstruction and requires weeks for cerebrospinal fluid (CSF) clearing, increasing the risks of ventriculits. Administration of intraventricular fibrinolytic agents and endoscopic evacuation have been proposed as alternative treatments, but with equally poor results. We present a retrospective analysis of two groups of patients who respectively underwent endoscope-assisted microsurgical evacuation versus EVD for the treatment of cast IVH. In a 10-year time, 25 patients with cast IVH underwent microsurgical, endoscope-assisted evacuation. Twenty-seven were instead treated by EVD. The two groups were compared in terms of hematoma evacuation, CSF clearing time, infection rates, need for permanent shunting, short/long-term survival, and functional outcome. In endoscope-assisted surgeries, full CSF clearance required 14 ± 3 days in 20 patients and 21 ± 3 days in 5; in the EVD group, 21 ± 3 days were needed in 12 patients, 28 ± 3 days in 11, and 35 ± 3 days in 4. Permanent shunting was inserted respectively in 19 endoscopic and 23 EVD patients. Final mRs score was 0-3 in 13 endoscopic cases, 4-5 in the remaining 12. In the EVD group, 7 subjects scored mRs 0-3, 16 scored 4-5; 4 died. In our experience, endoscope-assisted evacuation of cast IVH reduced ICU staying and CSF clearance times. It also seemed to improve neurological outcome, but without affecting the need for permanent shunt. On the counterside, it increases the number of severely disabled survivors.
