Abstract
BACKGROUND Subarachnoid haemorrhage (SAH) and intraventricular haemorrhage (IVH) are associated with poor patient outcomes. Intraventricular fibrinolysis is effective in clearing IVH and improving patient survival and neurological outcome. By similar rationale, cisternal irrigation has been proposed as a potential method to accelerate haematoma clearance in SAH. We aimed to provide a comprehensive review and meta-analysis evaluating the effect of intraventricular and cisternal irrigation on clinical outcomes in patients with SAH and IVH. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed preparing this systematic review and study selection was performed by multiple investigators. We extracted ORs from the individual studies and aggregated these using a random effects model. The quality of evidence was evaluated using Grading of Recommendations, Assessment, Development and Evaluations assessment and ROBINS-I or RoB-2. RESULTS 24 articles were included. In SAH, we found that cisternal irrigation with fibrinolytic agents was associated with reduced mortality (OR: 0.68, 95% CI 0.46 to 1.00), higher probability of favourable functional outcome (OR: 1.80, 95% CI 1.30 to 2.51), and reduced risks of DCI (OR: 0.28, 95% CI 0.18 to 0.42) and cerebral vasospasm (OR: 0.28, 95% CI 0.18 to 0.42), compared with conventional therapy. Cisternal irrigation with vasodilatory agents was associated with lower mortality (OR: 0.32, 95% CI 0.13 to 0.79) and reduced risk of cerebral vasospasm (OR: 0.37, 95% CI 0.17 to 0.79). The evidence for irrigation therapy of IVH was sparse and insufficient to show any significant effect. CONCLUSION In this study, we found that cisternal irrigation could improve the prognosis in patients with SAH compared with conventional therapy. There is no evidence to support cisternal irrigation treatment of IVH.

Abstract
PURPOSE Intrathecal vasoactive drugs have been proposed in patients with aneurysmal subarachnoid hemorrhage (aSAH) to manage cerebral vasospasm (CV). We analyzed the efficacy of intracisternal nicardipine compared to intraventricular administration to a control group (CG) to determine its impact on delayed cerebral ischemia (DCI) and functional outcomes. Secondary outcomes included the need for intra-arterial angioplasties and the safety profile. METHODS We performed a retrospective analysis of prospectively collected data of all adult patients admitted for a high modified Fisher grade aSAH between January 2015 and April 2022. All patients with significant radiological CV were included. Three groups of patients were defined based on the CV management: cisternal nicardipine (CN), ventricular nicardipine (VN), and no intrathecal nicardipine (control group). RESULTS Seventy patients met the inclusion criteria. Eleven patients received intracisternal nicardipine, 18 intraventricular nicardipine, and 41 belonged to the control group. No cases of DCI were observed in the CN group (p = 0.02). Patients with intracisternal nicardipine had a reduced number of intra-arterial angioplasties when compared to the control group (p = 0.03). The safety profile analysis showed no difference in complications across the three groups. Intrathecal (ventricular or cisternal) nicardipine therapy improved functional outcomes at 6 months (p = 0.04) when compared to the control group. CONCLUSION Administration of intrathecal nicardipine for moderate to severe CV reduces the rate of DCI and improved long-term functional outcomes in patients with high modified Fisher grade aSAH. This study also showed a relative benefit of cisternal over intraventricular nicardipine, thereby reducing the number of angioplasties performed in the post-treatment phase. However, these preliminary results should be confirmed with future prospective studies.

The Local Intraarterial Administration of Nimodipine Might Positively Affect Clinical Outcome in Patients with Aneurysmal Subarachnoid Hemorrhage and Delayed Cerebral Ischemia. J Clin Med 2022; 11:jcm11072036. [PMID: 35407643 PMCID: PMC8999377 DOI: 10.3390/jcm11072036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 03/26/2022] [Accepted: 04/01/2022] [Indexed: 12/10/2022] Open
Abstract
The effect of the intraarterial administration of nimodipine as a rescue measure to treat delayed vasospasm after aSAH remains understudied; therefore, we evaluated its effect on short- and long-term functional and neuropsychological outcomes after aSAH. In this prospective observational study, a total of 107 consecutive patients treated for aSAH of WFNS grades I−V were recruited. At follow-up visits 3-, 12- and 24-months after the hemorrhage, functional outcome was assessed using the Extended Glasgow Outcome (GOSE) and modified Rankin (mRS) scales, while neurocognitive function was evaluated using the screening module of the Neuropsychological Assessment Battery (NAB-S). The outcome of patients, who had received rescue therapy according to the local standard treatment protocol (interventional group, n = 37), and those, who had been treated conservatively (conservative group, n = 70), were compared. Even though significantly more patients in the interventional treatment group suffered from high-grade aSAH (WFNS Grades IV and V, 54.1% vs. 31.4%, p = 0.04) and required continuous drainage of cerebrospinal fluid at discharge (67.7% vs. 37.7%, p = 0.02) compared to the control group, significant differences in functional outcome were present only at discharge and three months after the bleeding (GOSE > 4 in 8.1% vs. 41.4% and 28.6% vs. 72.7%, p < 0.001 and p = 0.01 for the interventional and control group, respectively). Thereafter, group differences were no longer significant. While significantly more patients in the intervention group had severe neuropsychological deficits (76.3% vs. 36.0% and 66.7% vs. 29.2%, p = 0.04 and 0.05, respectively) and were unable to work (5.9% vs. 38.1%, p = 0.03 at twelve months) at three and twelve months after the hemorrhage, no significant differences between the two groups could be detected at long-term follow-up. The presence of moderate neuropsychological impairments did not significantly differ between the groups at any timepoint. In conclusion, despite initially being significantly more impaired, patients treated with intraarterial administration of nimodipine reached the same functional and neuropsychological outcomes at medium- and long-term follow-up as conservatively treated patients suggesting a potential beneficial effect of intraarterial nimodipine treatment for delayed vasospasm after aSAH.

Abstract
Hemorrhage in the central nervous system (CNS), including intracerebral hemorrhage (ICH), intraventricular hemorrhage (IVH), and aneurysmal subarachnoid hemorrhage (aSAH), remains highly morbid. Trials of medical management for these conditions over recent decades have been largely unsuccessful in improving outcome and reducing mortality. Beyond its role in creating mass effect, the presence of extravasated blood in patients with CNS hemorrhage is generally overlooked. Since trials of surgical intervention to remove CNS hemorrhage have been generally unsuccessful, the potent neurotoxicity of blood is generally viewed as a basic scientific curiosity rather than a clinically meaningful factor. In this review, we evaluate the direct role of blood as a neurotoxin and its subsequent clinical relevance. We first describe the molecular mechanisms of blood neurotoxicity. We then evaluate the clinical literature that directly relates to the evacuation of CNS hemorrhage. We posit that the efficacy of clot removal is a critical factor in outcome following surgical intervention. Future interventions for CNS hemorrhage should be guided by the principle that blood is exquisitely toxic to the brain.

Abstract
BACKGROUND Delayed cerebral infarction (DCI) is a major cause of death and poor neurological outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). Direct intrathecal therapies with fibrinolytic and spasmolytic drugs have appeared promising in clinical trials. However, access to the subarachnoid space for intrathecal drug administration is an unsolved problem so far, especially in patients with endovascular aneurysm securing. We investigate a therapy protocol based on stereotactic catheter ventriculocisternostomy (STX-VCS), a new approach to overcome this problem. The primary objective of this study is to assess whether cisternal lavage with urokinase, nimodipine, and Ringer's solution administered via a stereotactically implanted catheter into the basal cisterns (= investigational treatment (IT)) is safe and improves neurological outcome in patients with aSAH. METHODS This is a randomized, controlled, parallel-group, open-label phase II trial. Fifty-four patients with severe aSAH (WFNS grade ≥ 3) will be enrolled at one academic tertiary care center in Southern Germany. Patients will be randomized at a ratio of 1:1 to receive either standard of care only or standard of care plus the IT. The primary endpoint is the proportion of subjects with a favorable outcome on the Modified Rankin Scale (defined as mRS 0-3) at 6 months after aSAH. Further clinical and surrogate outcome parameters are defined as secondary endpoints. DISCUSSION New approaches for the prevention and therapy of secondary brain injury in patients with aSAH are urgently needed. We propose this RCT to assess the clinical safety and efficacy of a novel therapy protocol for intrathecal administration of urokinase, nimodipine, and Ringer's solution.

Abstract
Background and Purpose- Delayed cerebral infarction (DCI) is an important cause of morbidity and mortality in patients with aneurysmal subarachnoid hemorrhage (aSAH). Stereotactic catheter ventriculocisternostomy (STX-VCS) and fibrinolytic/spasmolytic lavage is a new method for DCI prevention. Here, we assess the effects of implementing STX-VCS in an unselected aSAH patient population of a tertiary referral center. Methods- Retrospective cohort study of all consecutive aSAH patients admitted to a neurosurgical referral center during a 7-year period (April 2012 to April 2019). Midterm STX-VCS was introduced and offered to patients at high risk for DCI. We compared the incidence and burden of DCI, neurological outcome, and the use of induced hypertension and endovascular rescue therapy in this consecutive aSAH population 3.5 years before versus 3.5 years after STX-VCS became available. Results- Four hundred thirty-six consecutive patients were included: 222 BEFORE and 214 AFTER. Fifty-seven of 214 (27%) patients received STX-VCS. Stereotactic procedures resulted in one (2%) subdural hematoma. Favorable neurological outcome at 6 months occurred in 118 (53%) patients BEFORE and 139 (65%) patients AFTER (relative risk, 0.79 [95% CI, 0.66-0.95]). DCI occurred in 40 (18.0%) patients BEFORE and 17 (7.9%) patients AFTER (relative risk, 0.68 [95% CI, 0.57-0.86]), and total DCI volumes were 8933 (100%) and 3329 mL (36%), respectively. Induced hypertension was used in 97 (44%) and 30 (15%) patients, respectively (relative risk, 0.55 [95% CI, 0.46-0.65]). Thirty (13.5%) patients BEFORE versus 5 (2.3%) patients AFTER underwent endovascular rescue therapies (relative risk, 0.17 [95% CI, 0.07-0.42]). Conclusions- Selecting high-risk patients for STX-VCS reduced the DCI incidence, burden, and related mortality in a consecutive aSAH patient population. This was associated with an improved neurological outcome.

Abstract
Background and Purpose- The PILLAR (Extracorporeal Filtration of Subarachnoid Hemorrhage via Spinal Catheter) study is a first-in-human trial of cerebrospinal fluid (CSF) filtration in aneurysmal subarachnoid hemorrhage. The study evaluates the safety and feasibility of a novel filtration system to rapidly remove blood and blood breakdown products from CSF after securement of a ruptured aneurysm. Methods- Patients with aneurysmal subarachnoid hemorrhage had a dual-lumen lumbar, intrathecal catheter placed after aneurysm securement and received up to 24 hours of CSF filtration (neurapheresis therapy). The catheter aspirated blood-contaminated CSF from the lumbar cistern and returned filtered CSF to the thoracic subarachnoid space. Neuro checks were performed q2 hours, and CSF samples were collected for cell counts, total protein, and gram stain. Computed tomography scans were acquired at baseline and post-filtration. Clinical follow-up occurred at 2 weeks and 30 days. Results- Thirteen patients had a catheter placed (mean time 24:13 hours after ictus). The system processed 632.0 mL (180.6-1447.6 mL) CSF in 15:07 hours (5:32-24:00 hours) of filtration. The mean initial CSF red blood cell count, 2.78×105 cells/µL, reduced to 1.17×105 cells/µL after filtration (52.9% reduction), and total protein reduced 71%. Independent analysis of baseline and postfiltration computed tomographies found notable cisternal blood decrease, with 46.5% mean Hijdra Score reduction. Three mild, anticipated adverse events were reported. Conclusions- The initial safety and feasibility of Neurapheresis therapy in aneurysmal subarachnoid hemorrhage demonstrated the potential to safely filter CSF and remove blood and blood byproducts. Future studies are warranted. Clinical Trial Registration- URL: https://www.clinicaltrials.gov. Unique identifier: NCT0287263.

Abstract
Delayed cerebral infarction (DCI) contributes to the burden of morbidity and mortality acquired by patients with aneurysmal subarachnoid hemorrhage (SAH). Cisternal lavage may prevent DCI. Delivery of lavage therapy to the basal cisterns, however, is challenging. Here, we report a novel method for the delivery of cisternal lavage using a cisterno-ventricular catheter (CVC) inserted via the fenestrated lamina terminalis during aneurysm clipping. In two high-risk aSAH patients a CVC was inserted into the third ventricle through the fenestrated lamina terminalis during aneurysm clipping. Post-operatively, continuous cisternal lavage using Urokinase or Nimodipine was applied using an external ventricular drain (EVD) as inflow tract and the CVC as outflow tract. Neurological outcome at 6 months was assessed by modified Rankin scale. Catheter placement into the third ventricle through the fenestrated lamina terminalis was performed without complications. Application of a free-running electrolyte solution containing Urokinase or Nimodipine via the EVD and drainage via the CVC was feasible. Cisternal Nimodipine application normalized sonographic vasospasm in both cases. DCI did not occur. CVC placement for ventriculo-cisternal lavage may represent a useful method for DCI prevention. It can be considered in aSAH patients at risk for DCI if the chiasmatic region is accessed during aneurysm clipping.

Abstract
Delayed Cerebral Infarction (DCI) due to Cerebral Vasospasm (CVS) is an important contributor to poor outcome after aneurysmal subarachnoid haemorrhage (aSAH). Despite established risk factors CVS and DCI are unpredictable at the individual patient level. Efficient treatments are lacking. We report a novel rescue therapy for DCI: Access to the basal cisterns by stereotactic catheter ventriculocisternostomy (STX-VCS) and direct cisternal application of the spasmolytic agent Nimodipine. On the basis of individual treatment decisions three aSAH patients who developed CVS underwent STX-VCS. Continuous lavage with Nimodipine was performed. CVS was assessed by daily transcranial doppler ultrasonography. Neurological outcome at 3 months was assessed by modified Rankin scale. STX-VCS was performed without complications in all patients. CVS rapidly resolved upon cisternal application of Nimodipine. CVS recurred in two patients upon interruption of Nimodpine application and resolved upon restart of Nimodipine. DCI did not occur in all three cases. STX-VCS and cisternal Nimodipine application is a novel rescue therapy for CVS treatment and DCI-prevention in patients with aSAH.

Prognostic Model for Chronic Shunt-Dependent Hydrocephalus After Aneurysmal Subarachnoid Hemorrhage. World Neurosurg 2019; 124:e572-e579. [PMID: 30639492 DOI: 10.1016/j.wneu.2018.12.156] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2018] [Revised: 12/14/2018] [Accepted: 12/17/2018] [Indexed: 11/24/2022]
Abstract
BACKGROUND Patients with aneurysmal subarachnoid hemorrhage (aSAH) are at risk of the development of chronic shunt-dependent hydrocephalus. However, identification of shunt-dependent patients remains challenging. We sought to develop a prognostic model to identify patients with aSAH at risk of chronic shunt-dependent hydrocephalus. In addition to the well-known prognostic variables, blood clearance in the cerebrospinal fluid (CSF) spaces was considered. METHODS We retrospectively analyzed the data from 227 patients treated at our institution from January 2012 to January 2016. The outcome was ventriculoperitoneal shunt placement within 30 days after aSAH. The candidate prognostic variables were patient age, World Federation of Neurological Surgeons grade and Fisher grade, external ventricular drainage, ventricular and intracerebral hemorrhage, and interval to blood clearance in the peripheral/basal CSF spaces. Adjustment for multiple testing was performed. Multivariable logistic regression analysis was used for model development. Bootstrapping was applied for internal validation. The model performance measures included indexes for explained variance (R2), calibration (graphic plot, Hosmer-Lemeshow test), and discrimination (c-statistic). RESULTS Of the 227 patients, 90 (39.6%) required a ventriculoperitoneal shunt. The constructed prognostic model combined external ventricular drainage placement, the presence of ventricular blood, and the duration of blood clearance in the basal cisterns. The model performance was promising, with an R2 of 33% (20% after bootstrapping), the calibration plot was adequate, the Hosmer-Lemeshow test result was not significant, and the c-statistic was 0.85 (0.84 as assessed after bootstrapping) indicating a good discriminating prognostic model. CONCLUSIONS Our prognostic model could help identify patients requiring permanent CSF diversion after aSAH, although additional modification and external validation are needed. Interventions aimed at accelerating the clearance of blood in the basal cisterns might have the potential to prevent the development of chronic hydrocephalus after aSAH.

Feasibility of stereotactic catheter ventriculocisternostomy for cisternal lavage therapy in patients with subarachnoid hemorrhage. Clin Neurol Neurosurg 2017; 163:94-102. [PMID: 29096139 DOI: 10.1016/j.clineuro.2017.10.012] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2017] [Revised: 10/11/2017] [Accepted: 10/15/2017] [Indexed: 11/26/2022]
Abstract
OBJECTIVE Delayed cerebral infarction (DCI) confers considerable morbidity and mortality after aneurysmal subarachnoid hemorrhage (aSAH). Available prevention strategies are insufficient. Cisternal blood clearance by stereotactic catheter ventriculocisternostomy (STX-VCS) and cisternal lavage therapy is a novel concept for DCI prevention. Here, we assess the general feasibility, pitfalls and imaging requirements of STX-VCS after aSAH. PATIENTS AND METHODS 73 aSAH patients admitted between 2008 and 2015 with appropriate imaging for simulation of stereotactic procedures were included. Surgical feasibility of a transventricular trajectory to the basal cisterns was assessed. RESULTS Transventricular catheter access to the basal cisterns was feasible in 94% of cases. In 6% vascular obstacles precluded a transventricular approach and access to the basal cisterns could be simulated via a transparenchymal trajectory. CT-artifacts that interfered with stereotactic planning were observed in 58% after coiling and 5% after clipping. In these cases stereotactic planning was enabled by MRI. Logistic regression of aneurysm size and distance-to-target allowed for precise prediction whether MRI was required for stereotactic planning of STX-VCS after coiling. CONCLUSIONS Stereotactic catheter access to the basal cisterns after aSAH appears to be generally feasible. Coil artifacts compromising CT-based planning can be precisely anticipated and planning enabled by MRI.
