Effect of Early External Ventricular Drainage on Perihemorrhagic Edema and Functional Outcome in Patients with Intraventricular Hemorrhage. World Neurosurg 2023; 175:e1059-e1068. [PMID: 37087041 DOI: 10.1016/j.wneu.2023.04.069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 04/13/2023] [Accepted: 04/15/2023] [Indexed: 04/24/2023]
Abstract
OBJECTIVE External ventricular drainage (EVD) is the most common neurosurgical procedure that allows drainage of cerebrospinal fluid and intraventricular blood. A specific time threshold for insertion of an EVD catheter in patients with spontaneous intracerebral hemorrhage and intraventricular hemorrhage has not been established. This study aimed to evaluate the association of early EVD with functional outcome in patients with intracerebral hemorrhage and intraventricular hemorrhage. METHODS Propensity score matching was used to account for baseline imbalances. Modified Rankin Scale score at 3 and 6 months, mortality rates at 3 and 6 months, postoperative complications, time course of edema evolution, and peak perihemorrhagic edema (PHE) were compared in patients who received early EVD versus routine EVD. RESULTS The rate of favorable outcome at 3 months was higher in the early EVD group compared with the routine EVD group. There were no differences between groups in modified Rankin Scale score at 6 months or mortality rates at 3 and 6 months. Absolute peak PHE and relative PHE volumes were significantly less in the early EVD group compared with the routine EVD group. The incidence of postoperative infections was lower in the early EVD group compared with the routine EVD group. CONCLUSIONS Early EVD was associated with improved functional outcome at 3 months, reduced PHE, and lower rate of infection in intracerebral hemorrhage and intraventricular hemorrhage. However, survival at 3 and 6 months and functional outcome at 6 months were not improved.

Abstract
Intracerebral hemorrhage (ICH) and intraventricular hemorrhage (IVH) carry a very dismal prognosis. Several medical and surgical attempts have been made to reduce mortality and to improve neurological outcomes in survivors. Aggressive surgical treatment of ICH through craniotomy and microsurgical evacuation did not prove to be beneficial to these patients, compared to the best medical treatment. Similarly, the conventional treatment of IVH using an EVD is often effective in controlling ICP only initially, as it is very likely for the EVD to become obstructed by blood clots, requiring frequent replacements with a consequent increase of infection rates.Minimally invasive techniques have been proposed to manage these cases. Some are based on fibrinolytic agents that are infused in the hemorrhagic site through catheters with a single burr hole. Others are possible thanks to the development of neuroendoscopy. Endoscopic removal of ICH through a mini-craniotomy or a single burr hole, and via a parafascicular white matter trajectory, proved to reduce mortality in this population, and further randomized trials are expected to show whether also a better neurological outcome can be obtained in survivors. Moreover, endoscopy offers the opportunity to access the ventricular system to aspirate blood clots in patients with IVH. In such cases, the restoration of patency of the entire CSF pathway has the potential to improve outcome and reduce complications and now it is believed to decrease shunt-dependency.

Neuroprotective effect of magnesium supplementation on cerebral ischemic diseases. Life Sci 2021; 272:119257. [PMID: 33631176 DOI: 10.1016/j.lfs.2021.119257] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 01/31/2021] [Accepted: 02/19/2021] [Indexed: 02/07/2023]
Abstract
Ischemic encephalopathy is associated with a high mortality and rate of disability. The most common type of ischemic encephalopathy, ischemic stroke, is the second leading cause of death in the world. At present, the main treatment for ischemic stroke is to reopen blocked blood vessels. However, despite revascularization, many patients are not able to achieve good functional results. At the same time, the strict time window (<4.5 h) of thrombolytic therapy limits clinical application. Therefore, it is important to explore effective neuroprotective drugs for the treatment of ischemic stroke. Magnesium is a natural calcium antagonist, which exerts neuroprotective effects through various mechanisms. However, while most basic studies have shown that magnesium supplementation can help treat cerebral ischemia, intravenous magnesium supplementation in large clinical trials has failed to improve prognosis of ischemic patients. Therefore, we review the basic and clinical studies of magnesium supplementation for cerebral ischemia. According to the route of administration, treatment can be divided into intraperitoneal magnesium supplementation, intravenous magnesium supplementation, arterial magnesium supplementation and intracranial magnesium supplementation. We also summarized the potential influencing factors of magnesium ion intervention in cerebral ischemia injury. Finally, in combination with influencing factors derived from basic research, this article proposes three future research directions, including magnesium supplementation into the circulatory system combined with magnesium supplementation in the lateral ventricle, magnesium supplementation in the lateral ventricle combined with hypothermia therapy, and lateral ventricle magnesium supplementation combined with intracarotid magnesium supplementation combined with selective hypothermia.

Abstract
New evidence and increased use of intracranial devices have increased the frequency of intraventricular (IVT) medication administration in the neurologic intensive care unit. Significant benefits and risks are associated with administration of medications directly into the central nervous system. This review summarizes important literature, along with key information for clinicians regarding the administration, dosing, monitoring, and adverse effects related to IVT medication usage. Multiple medications have supporting literature for their use in critically ill patients including amphotericin B, aminoglycosides, colistimethate, daptomycin, quinupristin/dalfopristin, vancomycin, alteplase, and nicardipine. Sterile preparation and delivery, along with different types of devices that support medication administration, are also reviewed. One randomized, placebo-controlled trial of alteplase demonstrated decreased mortality but no change in good functional outcome. Other reports of IVT medication use are mainly limited to case reports and retrospective case series. There is a need for increased research on the topic; however, several practical barriers decrease the likelihood of a large, placebo-controlled, prospective study for most indications. Providers should consider implementing protocols to maximize safety of IVT medication delivery to ensure optimal patient outcomes.

Abstract
Objective Stroke is the fifth leading cause of death in the United States and the leading cause of disability. Hemorrhagic stroke has higher risks of mortality and neurologic deficit. Higher still, acute intraventricular hemorrhage (IVH) has mortality between 50% and 80% while complicating subarachnoid hemorrhage in 15% of cases and intracerebral hemorrhage in 40% of cases. We sought to demonstrate that early adjuvant intraventricular recombinant tissue plasminogen activating factor (rt-PA) improved outcomes. Methods Retrospective chart review was performed on patients aged 18-95 years with external ventricular drain (EVD) and intraventricular rt-PA for clot evacuation in IVH between 2005 and 2015. In total, 22 patients met the inclusion criteria. Generalized linear modeling was performed with factorial analysis using the Glasgow Coma Score (GCS) on arrival, GCS at EVD placement, EVD day of onset of rt-PA administration, GCS at onset of rt-PA administration, total duration of EVD, necessity of ventriculoperitoneal (VP) shunt, occurrence of ventriculitis, day of ventriculitis, GCS after rt-PA, length of stay (LOS) in the intensive care unit (ICU), and hospital disposition. Results Presenting GCS affected LOS significantly. Ventriculitis only significantly affected ICU LOS. GCS after rt-PA only significantly affected discharge GCS. EVD day of rt-PA protocol commencement demonstrated significant effects on EVD duration and cerebrospinal fluid (CSF) diversion requirement. Age affected ICU and hospital LOS. Conclusion These findings argue for larger prospective trials of EVD day two rt-PA protocol inception in acute IVH. Reported ventriculitis rates with EVDs are 8.8%, while we demonstrated a rate of 18% without significant effects except in ICU LOS. Transcatheter intraventricular rt-PA is safe and effective as an adjuvant in acute spontaneous intraventricular hemorrhage with the greatest benefit of rt-PA protocol at EVD day two.

Abstract
A 51-year-old woman with a history of idiopathic aqueduct stenosis, treated initially with insertion of a ventriculo peritoneal shunt, presented to our institution with shunt dysfunction. She had previously undergone multiple shunt revisions for shunt infection, shunt blockage and low-pressure symptoms, most recently with conversion to a ventriculo atrial (VA) shunt. Her VA shunt was again revised, with replacement of the ventricular catheter, however surgery was complicated by a large intraventricular haemorrhage (IVH) requiring placement of an external ventricular drain (EVD). Prior to eventual removal of her EVD it was determined that the VA shunt had blocked as a result of the IVH. Subsequently alteplase, a recombinant tissue plasminogen activator (tPA), was administered into the shunt reservoir, resulting in successful return of shunt function, therefore avoiding the need for further shunt revision. This is the first description of the use of tPA to unblock a shunt obstructed by blood.

Abstract
OBJECTIVE Frame-based stereotactic surgical planning systems (SSPSs) have been used for deep brain stimulation and radioneurosurgery. Here, we evaluated the feasibility, safety and efficacy of using a SSPS to aid spontaneous intracerebral haematoma (ICH) treatment. METHODS Patients with moderate spontaneous putamen haematomas were randomized into two groups: treatment (group A) and control (group B). In group B, the catheter for evacuating haematomas was inserted into a target point, located at the centre of the haematoma, using conventional frame-based stereotactics; urokinase thrombolysis was subsequently delivered through the catheter. In group A, this procedure was assisted by a SSPS, which designed both the target point and trajectory in the haematoma through virtual reality. Duration of evacuating haematomas and number of urokinase injections was compared between groups. RESULTS In total, 65 patients were recruited: in group A (n = 30), the duration of evacuating haematomas (35.27 ± 9.17 h) was shorter than in group B (n = 35; 67.77 ± 13.82 h). There were fewer urokinase injections in group A (3.63 ± 1.16) than in group B (6.40 ± 1.29). CONCLUSIONS The feasibility, efficacy and safety of spontaneous ICH treatment were optimized by the use of a frame-based SSPS.

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
BACKGROUND Little is known about the efficacy of single versus dual extraventricular drain (EVD) use in intraventricular hemorrhage (IVH), with and without thrombolytic therapy. METHODS Post-hoc analysis of seven patients with dual bilateral EVDs from two multicenter trials involving 100 patients with IVH, and spontaneous intracerebral hemorrhage (ICH) volume <30 ml requiring emergency external ventricular drainage. Seven "control" patients with single catheters were matched by IVH volume and distribution and treatment assignment. Head CT scans were obtained daily during intraventricular injections for quantitative determination of IVH volume. RESULTS Median [min-max] age of the 14 subjects was 56 [40-73] years. Median duration of EVD was 7.9 days (single catheter group) versus 12.2 days (dual catheter group) (P = 0.34). Baseline median IVH volume was not significantly different between groups (75.4 ml [22.4-105.1]--single EVD vs. 84.5 ml [42.0-132.0]--dual EVD; P = 0.28). Comparing the change in IVH volume on time-matched CT scans during dual EVD use, the median decrease in IVH volume in dual catheter patients was significantly larger (52.1 [31.7-81.1] ml) versus single catheter patients (34.5 [13.1-73.9] ml) (P = 0.004). There was a trend to greater decrease in IVH volume during dual EVD use in both rt-PA (P = 0.9) and placebo-treated (P = 0.11) subgroups. CONCLUSION The decision to place dual EVDs is generally reserved for large IVH (>40 ml) with casting and mass effect. The use of dual simultaneous catheters may increase clot resolution with or without adjunctive thrombolytic therapy.

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
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
OPINION STATEMENT Intracerebral hemorrhage is a medical emergency. It is the most deadly and disabling form of stroke, and no individual therapy has been demonstrated to improve outcome. However, it appears that aggressive medical care in general, and management by neuroscience specialists in particular, offers substantial benefit. Therefore, providing the best supportive care based on currently available evidence may well improve outcomes. Airway management and management of blood pressure aimed at maximizing cerebral perfusion while minimizing ongoing bleeding, as well as rapid reversal of anticoagulation, are likely to be important in the early phase. Additionally, efforts should be undertaken to provide careful glucose management and temperature management and to maximize cerebral perfusion pressure. Selected patients are likely to benefit from external ventricular drainage or even hematoma evacuation. Except in rare circumstances, most patients should be managed in a neuroscience intensive care unit during the acute phase. Some patients appear to have no reasonable likelihood of recovery and can be considered for limitations of care such as Do Not Resuscitate orders or Comfort Measures Only orders. However, it can be difficult to accurately predict long-term outcome in the acute phase; formal prognostic tools should be used to offer information to patients and their families. After the hemorrhage has stabilized, efforts to minimize complications include thromboembolism prophylaxis, physical therapy, and acute rehabilitation.

Abstract
Intraventricular hemorrhage (IVH) subsequent to intracerebral hemorrhage (ICH) or subarachnoid hemorrhage (SAH) is associated with high mortality and morbidity. The use of fibrinolytic agents to treat this condition has previously been reported in small clinical trials with limited numbers of patients. Variability regarding inclusion criteria, method of administration and outcome have made it difficult to draw firm conclusions regarding the efficacy of antifibrinolytic therapy. Nine patients with CT-diagnosed IVH were treated with Alteplase intrathecally for 3 to 5 days according to the CT-verified clearance of IVH. After the treatment period, a repeat CT scan was performed to evaluate treatment effect.In this safety study, we achieved rapid removal of IVH compared to retrospective controls, without incidents of re-bleeding, with only 33% permanent shunt placements and a neurological outcome of GOS of 4-5 in 44% of the patients. Based on the above results, the treatment protocol was considered safe and highly effective. A prospective randomized national multicenter trial has been initiated in order to evaluate the efficacy of this novel method also in terms of outcome and shunt dependency.

Abstract
Brain hemorrhage is the most fatal form of stroke and has the highest morbidity of any stroke subtype. Intraventricular extension of hemorrhage (IVH) is a particularly poor prognostic sign, with expected mortality between 50% and 80%. IVH is a significant and independent contributor to morbidity and mortality, yet therapy directed at ameliorating intraventricular clot has been limited. Conventional therapy centers on managing hypertension and intracranial pressure while correcting coagulopathy and avoiding complications such as rebleeding and hydrocephalus. Surgical therapy alone has not changed the natural history of the disease significantly. However, fibrinolysis in combination with extraventricular drainage shows promise as a technique to reduce intraventricular clot volume and to manage the concomitant complications of IVH.

Abstract
OBJECTIVE Intraventricular hemorrhage (IVH) is associated with a poor outcome. External ventricular drainage together with clot lysis through intrathecal tissue plasminogen activator (IT-tPA) has been proposed as a promising therapy. However, recent experimental work has implicated tissue plasminogen activator (tPA) in the pathogenesis of cerebral edema. METHODS We reviewed the records of all patients with IVH caused by primary supratentorial intracerebral hemorrhage who underwent external ventricular drainage without surgical evacuation between January 2001 and June 2008. Of these 30 patients, we identified 13 who received IT-tPA. The remaining 17 patients served as controls. Hemorrhage, edema volume, and IVH score were determined on admission and by follow-up computed tomographic scans for 96 hours after admission. Discharge outcome was evaluated using the modified Rankin Scale. RESULTS There were no significant differences between the treatment and controls in terms of age, Glasgow Coma Scale score, Graeb and LeRoux IVH scores, or intracerebral hemorrhage volume on admission. IT-tPA resulted in more rapid clearance of IVH as determined by the 96-hour decrease in both the Graeb IVH score (tPA, 3.00 +/- .55; control, 1.00 +/- 0.57; P = .05) and the LeRoux IVH score (tPA, 6.2 +/- 0.80; control, 2.25 +/- 1.32; P = .05). Patients treated with IT-tPA demonstrated significantly larger peak ratios of edema to intracerebral hemorrhage volume (1.24 +/- 0.14 vs 0.70 +/- 0.08 in controls; P = .002). Additionally, increased rates of sterile meningitis (46% vs 12%; P = .049) and a trend toward shunt dependence (38% vs 6%; P = .06) were observed in the tPA cohort. Nevertheless, no significant differences in outcome at discharge or length of hospital stay were observed between cohorts. CONCLUSION Although IT-tPA hastens the resolution of IVH, it may worsen perihematomal edema formation. Larger prospective studies are required to confirm these findings and to determine whether outcome is adversely affected by IT-tPA administration.

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
Most cases of intraventricular hemorrhage (IVH) occur secondary to spontaneous intracerebral or subarachnoid hemorrhage. The main concern is development of hydrocephalus, which is related to a poor prognosis. Over the last years, several treatment options for IVH have been introduced, but prospective data regarding the efficacy of those therapies (external ventricular drainage, intraventricular fibrinolysis, lumbar drainage, endoscopic hematoma evacuation) do not yet exist. This review focuses on combined therapy using an external ventricular drain and intraventricular fibrinolysis with r-TPA for IVH-associated initial occlusive hydrocephalus. Moreover, a continuing treatment strategy for persistent malresorptive communicating hydrocephalus using lumbar drainage is described.

Abstract
Intraventricular hemorrhage (IVH) after bleeding from a cerebral aneurysm or an arteriovenous malformation (AVM) results in a high mortality. A limited number of publications have shown that intraventricular thrombolysis with e.g. recombinant tissue plasminogen activator (rt-PA) can be a therapeutic option in IVH. However, this treatment is considered as an absolute contraindication prior to the treatment of the bleeding source. We report the successful use of low-dose intraventricular thrombolysis (rt-PA) in two cases of life-threatening intraventricular hemorrhage due to periventricular AVMs as rescue therapy, even prior to source control of the bleeding. Our observations, together with nine comparable published cases, illustrate that this treatment might be useful to clear the intraventricular blood and lower intracranial pressure. It might also improve neurological outcome and mortality in these selected patients. This suggests that hemorrhage from a periventricular AVM, even before surgical resection or endovascular embolization, is not necessarily an absolute contraindication for intraventricular thrombolysis in patients with massive IVH.

Abstract
Over the recent years, fibrinolytic agents have been tested for intraventricular clot fibrinolysis (IVF). Compared with patients who did not receive IVF, administration of rt-PA induces rapid resorption of intraventricular blood and normalization of cerebrospinal fluid (CSF) circulation resulting in a reduced 30-day mortality and beneficial short-term outcome after 3 months. Our objective was to analyze possible influences of IVF on the long-term outcome after 12 months. Based on a prospective data base, patients with ganglionic supratentorial hematoma with additional intraventricular hemorrhage and occlusive hydrocephalus (n = 135) were isolated. Twenty-seven patients received IVF. To design a case-control study, we carefully matched 22 controls without IVF with regard to hematoma volume, Graeb score, Glasgow Coma Scale on admission and age (five patients remained unmatchable). We determined clinical and imaging parameters by reviewing the medical records and CT scans of all included patients. Outcome after 12 months was evaluated using the modified Rankin scale (mRS). One multivariate regression analysis was performed to determine predisposing factors for outcome. IVF significantly reduced Graeb score during treatment (eight on admission, three after IVF, one prior to discharge in the treated group versus 8/6/2 in patients without IVF). In patients with IVF requirement, a second external ventricular drainage (EVD) and a ventriculoperitoneal (VP) shunt were reduced (P = 0.08) and the incidence of a lumbar drainage was significantly higher (P < 0.01), whilst the overall time of extra-corporal CSF drainage was comparable. EVD associated complications were equal in both groups. Overall long-term outcome was poor but no significant differences were found between patients with and without IVF (mRS 4-6: 12/22 (54%) in patients with and 13/22 (59%) in patients without IVF; P = 0.81). The five excluded patients with IVF were similar to the 22 included ones with respect to imaging findings and outcome. The multivariate analysis revealed age and baseline hematoma volume, but not IVF to significantly impact the outcome. In accordance with previous studies, IVF hastened clot lysis and reduced the need for repeated EVD exchanges and permanent shunting. However, despite these advantages, IVF did not influence long-term outcome after 12 months. The results of the prospective randomized trial (Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage) need to be awaited.

Abstract
OBJECT In this study the authors analyzed the relationship of intraventricular hemorrhage (IVH) to in-hospital complications and clinical outcome in a large population of patients with aneurysmal subarachnoid hemorrhage (SAH). METHODS Data from 3539 patients with aneurysmal SAH were evaluated, and these data were obtained from four prospective, randomized, double-blind, placebo-controlled trials of tirilazad that had been conducted between 1991 and 1997. Clinical characteristics, in-hospital complications, and outcome at 3 months post-SAH (Glasgow Outcome Scale score) were analyzed with regard to the presence or absence of IVH. RESULTS Patients with SAH and IVH differ in demographic and admission characteristics from those with SAH but without IVH and are more likely to suffer in-hospital complications and a worse outcome at 3 months post-SAH. CONCLUSIONS The presence of IVH in patients with SAH has an important predictive value with regard to these aspects.

Abstract
OBJECT Only limited data exist addressing the long-term outcome of patients with ganglionic hemorrhage complicated by intraventricular hemorrhage (IVH) and hydrocephalus that requires an external ventricular drain (EVD). The aim of this study was to compare the long-term outcome of patients with pure ganglionic hemorrhage and those requiring an EVD due to additional IVH and hydrocephalus. METHODS For this study, 116 patients with supratentorial ganglionic hemorrhage and occlusive hydrocephalus were screened. To avoid any bias the authors excluded all patients with nonprimary intracerebral hemorrhage as well as those who received no treatment. Forty patients with IVH and subsequent hydrocephalus were examined, and 40 more patients with pure ganglionic hematomas were matched with regard to age, sex, Glasgow Coma Scale score, need for mechanical ventilation, and, in particular, hematoma volume. Outcome analysis was performed using the Barthel Index and the modified Rankin Scale (mRS). The mean hematoma volume was 25.3 +/- 15.2 ml. The overall long-term outcome was unfavorable (mRS Score 4-6) in 59% of all patients. Good outcome (mRS score < 4) was observed in 25 (62.5%) of 40 patients with hematoma volumes less than 25 ml, compared with eight (20%) of 40 who had hematoma volumes greater than 25 ml (p < 0.05, chi-square test). The need for an EVD was not associated with a worse long-term outcome in patients with comparable hematoma volumes. In contrast, the duration of treatment in the intensive care unit was longer for patients with EVDs than for those who had pure ganglionic hematomas (16 [range 5-29] days compared with 8 [range 2-19] days; p < 0.05, Mann-Whitney U-test), regardless of hematoma volume. CONCLUSIONS The long-term outcome of treated patients with supratentorial ganglionic hemorrhage with ventricular involvement and occlusive hydrocephalus is comparable to that of patients with similar hematoma volumes but no IVH.

Abstract
Hydrocephalus is an excess accumulation of cerebrospinal fluid in or around the brain that can be produced by a broad spectrum of disorders. It can develop at any age and its incidence is increasing, both in infants and adults. Although the standard treatment of hydrocephalus is cerebrospinal fluid shunting, there are certain circumstances in which medical treatment, alone or in combination with shunting, has been suggested as an alternative. This review aims to present and discuss the indications for pharmacological treatment in the medical management of hydrocephalus, and the drugs most frequently used. Carbonic anhydrase inhibitors, loop diuretic agents, osmotic agents and fibrinolytic therapy are discussed. The most suitable drug seems to be acetazolamide, alone or in combination with furosemide. At present, osmotic agents are no longer used in the treatment of hydrocephalus. Fibrinolytic therapy administered directly into the ventricular system may not avoid the need for shunt placement, but may help in the management of hydrocephalus by preventing or reducing the rate of catheter obstruction and accelerating clot resolution.

Abstract
OBJECTIVE Intraventricular hemorrhage (IVH) represents a clinicopathologic entity with a dismal prognosis. The associated mortality rate has been reported as high as 80%; the morbidity is also quite high. The use of various fibrinolytic agents (streptokinase, urokinase, and recombinant tissue-type plasminogen activator [rt-PA]) has been reported in a small number of clinical series with a very limited number of participants, yielding significant variability regarding inclusion criteria, treatment protocol, and outcome analysis. METHODS In our prospective study, we report our experience using rt-PA in 21 patients with IVH. Patients with IVH of aneurysmal or arteriovenous malformation origin were excluded. Intraventricular administration of rt-PA was initiated within 24 hours after the ictal event (dose, 3 mg every 24 hours) through a ventricular catheter. The patients' intracranial and cerebral perfusion pressures, cerebrospinal fluid (CSF) cell count, and head CT scans with emphasis to frontal horn dimension and inner cranium diameter at the same level ratio were collected and analyzed. RESULTS Good outcome was observed in 47.5% of our patients, whereas 28.5% died and 24.0% survived with severe disability. The development of rt-PA-associated complications was as follows: new hemorrhage in 19%, infection in 14.3%, and CSF pleocytosis in 100% of patients. Permanent CSF shunt was required in 40%. The intermediate (3-month) follow up of our survivors showed no significant outcome changes compared with the immediate (1-month) follow up. CONCLUSIONS Intraventricular administration of rt-PA appears to be beneficial in cases of IVH even though it is occasionally associated with serious complications. Further multi-institutional studies are required for validating this treatment modality and standardizing its parameters.

Abstract
OBJECTIVE Intraventricular hemorrhage is associated with a very poor outcome. Simple external ventricular drainage alone has not resulted in a decline of mortality. The aim was to study the effect of direct intraventricular administration of recombinant tissue plasminogen activator (rtPA). PATIENTS AND METHODS A retrospective series of eighteen adult patients with severe intraventricular hemorrhage, admitted to our university hospital, was studied for the effect of direct intraventricular administration of recombinant tissue plasminogen activator (rtPA). rtPA was administered in a dosage of 2mg. The injection was repeated at 12h intervals until serial CT scans showed a substantial reduction of intraventricular blood. RESULTS The total of rtPA doses per patient ranged from 2 to 32mg. Seven out of 18 patients showed good neurological recovery, 4 died. Only one patient had a complication which could be directly attributed to the intraventricular thrombolytic therapy. CONCLUSION We conclude that the procedure of intraventricular administration of a thrombolytic agent, i.e. rtPA, seems effective in lysis of the intraventricular hematoma and may, therefore, improve outcome.

Abstract
BACKGROUND Spontaneous or secondary intraventricular hemorrhage is a marker of poor prognosis for hemorrhagic stroke. It can cause hydrocephalus and require ventricular shunt placement, result in permanent neurological deficits or death. Fibrinolytic agents injected into the ventricular system could dissolve blood clots, increase the clearance of blood from the ventricles and hence improve outcome. OBJECTIVES To assess the clinical efficacy and safety of thrombolytic agents administered intraventricularly in the management of intraventricular hemorrhage in adults. SEARCH STRATEGY We searched the Cochrane Stroke Group Trials Register (last searched February 2002). In addition, we searched the Cochrane Controlled Trials Register, MEDLINE, EMBASE, Current Contents, and International Pharmacy Abstracts to 2001. We handsearched several neurosurgery journals and the references list of articles identified. SELECTION CRITERIA Randomised unconfounded studies comparing intraventricular fibrinolytic therapy to placebo or open control for the management of intraventricular hemorrhage in adults. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed all identified trials. Clinically significant information related to patient population, efficacy and safety were extracted and summarized. MAIN RESULTS A total of ten studies were identified by our search strategy. Eight of them were excluded because of case series designs or retrospective control group. One quasi-randomised trial used alternate allocation and was excluded. Only one report met the review criteria for randomization. The randomised trial reported good outcome but has important design flaws resulting in a biased control group and therefore was excluded. REVIEWER'S CONCLUSIONS There is anecdotal evidence suggesting that the intraventricular administration of fibrinolytic agents in intraventricular hemorrhage maybe of therapeutic value and safe. Thus far, there are no randomised trials of sufficient size and quality to evaluate the safety and efficacy of this treatment modality.
