RESUMO
OBJECTIVE: A trial comparing prenatal with postnatal open spina bifida (OSB) repair established that prenatal surgery was associated with better postnatal outcome. However, in the trial, fetal surgery was carried out through hysterotomy. Minimally invasive approaches are being developed to mitigate the risks of open maternal-fetal surgery. The objective of this study was to investigate the impact of a novel neurosurgical technique for percutaneous fetoscopic repair of fetal OSB, the skin-over-biocellulose for antenatal fetoscopic repair (SAFER) technique, on long-term postnatal outcome. METHODS: This study examined descriptive data for all patients undergoing fetoscopic OSB repair who had available 12- and 30-month follow-up data for assessment of need for cerebrospinal fluid (CSF) diversion and need for bladder catheterization and ambulation, respectively, from eight centers that perform prenatal OSB repair via percutaneous fetoscopy using a biocellulose patch between the neural placode and skin/myofascial flap, without suture of the dura mater (SAFER technique). Univariate and multivariate logistic regression analyses were used to examine the effect of different factors on need for CSF diversion at 12 months and ambulation and need for bladder catheterization at 30 months. Potential cofactors included gestational age at fetal surgery and delivery, preoperative ultrasound findings of anatomical level of the lesion, cerebral lateral ventricular diameter, lesion type and presence of bilateral talipes, as well as postnatal findings of CSF leakage at birth, motor level, presence of bilateral talipes and reversal of hindbrain herniation. RESULTS: A total of 170 consecutive patients with fetal OSB were treated prenatally using the SAFER technique. Among these, 103 babies had follow-up at 12 months of age and 59 had follow-up at 30 months of age. At 12 months of age, 53.4% (55/103) of babies did not require ventriculoperitoneal shunt or third ventriculostomy. At 30 months of age, 54.2% (32/59) of children were ambulating independently and 61.0% (36/59) did not require chronic intermittent catheterization of the bladder. Multivariate logistic regression analysis demonstrated that significant prediction of need for CSF diversion was provided by lateral ventricular size and type of lesion (myeloschisis). Significant predictors of ambulatory status were prenatal bilateral talipes and anatomical and functional motor levels of the lesion. There were no significant predictors of need for bladder catheterization. CONCLUSION: Children who underwent prenatal OSB repair via the percutaneous fetoscopic SAFER technique achieved long-term neurological outcomes similar to those reported in the literature after hysterotomy-assisted OSB repair. © 2021 The Authors.

BACKGROUND: The current study is an external validation of 4 scoring models proposed in the literature for predicting ventriculoperitoneal shunt insertion after aneurysmal subarachnoid hemorrhage (aSAH) using retrospective patient data from Sheffield Teaching Hospital (STH). METHODS: Data were collected on various demographics, and patients were individually scored using the 4 scoring models. Models were compared with each other using receiver-operator characteristic curves. The best model had the highest area under the curve. RESULTS: A total of 301 aSAH patients were referred to the neurosurgery department in STH between 1 January 2014 and 31 December 2017. Scoring model 4 also had the largest area under the curve of 0.853 (P < 0.001), and scoring model 3 had the lowest area under the curve of 0.654 (P = 0.036). CONCLUSIONS: Scoring model 4 was found to be the best scoring model out of the 4 scoring models externally validated to predict shunt dependency after an aSAH in STH patients. Scoring model 4 is less applicable in modern practice due to a higher proportion of coiling and use of the Hunt and Hess scale grade. A new scoring model is needed to predict shunt insertion in modern practice.

Aim The aim of this study is to outline the role of primary external ventricular drains (EVD) in the management of open myelomeningoceles in the neonatal setting in Ireland. Methods Retrospective cohort study involving all infants who underwent open myelomeningocele repair in a teritary centre in Ireland between January 2009 and April 2016. Medical charts and laboratory data was reviewed on all infants meeting the inclusion criteria. Results One hundred and forty-three neonates underwent open myelomeningocele repair in the 6.5 year period. EVD were inserted at the time of primary wound closure in 19 cases (13%). EVD were used to aid in wound closure and as a primary method of cerebrospinal fluid (CSF) diversion. They remained in place for a median of 8 days, ranging from 1-22 days. All EVD, apart from one, in our series were replaced by a ventricular-peritoneal (VP) shunt at some stage. Conclusion EVD were used in 13% of cases of open myelomeningocele repairs from Jan 2009-Apr 2016 as a primary measure to aid in management. Compared to the cohort in whom an EVD was not inserted at the time of surgery, there was a decrease in the rate of infections. However, there was an increased rate of wound dehiscence/leak and a later need for VP shunt insertion.

OBJECTIVE: At failure of endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC), the ETV ostomy may be found to be closed or open. Failure with a closed ostomy may indicate a population that could benefit from evolving techniques to keep the ostomy open and may be candidates for repeat ETV, whereas failure with an open ostomy may be due to persistently abnormal CSF dynamics. This study seeks to identify clinical and radiographic predictors of ostomy status at the time of ETV/CPC failure. METHODS: The authors conducted a multicenter, retrospective cohort study on all pediatric patients with hydrocephalus who failed initial ETV/CPC treatment between January 2013 and October 2016. Failure was defined as the need for repeat ETV or ventriculoperitoneal (VP) shunt placement. Clinical and radiographic data were collected, and ETV ostomy status was determined endoscopically at the subsequent hydrocephalus procedure. Statistical analysis included the Mann-Whitney U-test, Wilcoxon rank-sum test, t-test, and Pearson chi-square test where appropriate, as well as multivariate logistic regression. RESULTS: Of 72 ETV/CPC failures, 28 patients (39%) had open-ostomy failure and 44 (61%) had closed-ostomy failure. Patients with open-ostomy failure were older (median 5.1 weeks corrected age for gestation [interquartile range (IQR) 0.9-15.9 weeks]) than patients with closed-ostomy failure (median 0.2 weeks [IQR -1.3 to 4.5 weeks]), a significant difference by univariate and multivariate regression. Etiologies of hydrocephalus included intraventricular hemorrhage of prematurity (32%), myelomeningocele (29%), congenital communicating (11%), aqueductal stenosis (11%), cyst/tumor (4%), and other causes (12%). A wider baseline third ventricle was associated with open-ostomy failure (median 15.0 mm [IQR 10.3-18.5 mm]) compared to closed-ostomy failure (median 11.7 mm [IQR 8.9-16.5 mm], p = 0.048). Finally, at the time of failure, patients with closed-ostomy failure had enlargement of their ventricles (frontal and occipital horn ratio [FOHR], failure vs baseline, median 0.06 [IQR 0.00-0.11]), while patients with open-ostomy failure had no change in ventricle size (median 0.01 [IQR -0.04 to 0.05], p = 0.018). Previous CSF temporizing procedures, intraoperative bleeding, and time to failure were not associated with ostomy status at ETV/CPC failure. CONCLUSIONS: Older corrected age for gestation, larger baseline third ventricle width, and no change in FOHR were associated with open-ostomy ETV/CPC failure. Future studies are warranted to further define and confirm features that may be predictive of ostomy status at the time of ETV/CPC failure.

OBJECTIVE: We explored the external ventricular drain (EVD) practices in Thailand. METHODS: We performed a survey-based study to describe EVD insertion, maintenance, quality improvement (QI) practices, and incidence of EVD infection. RESULTS: The study included 58 of 101 hospitals contacted (57.4% response rate), with ≥600 beds (44.8%) and dedicated neurocritical care units (53%). The reasons for EVD placement included aneurysmal subarachnoid hemorrhage, traumatic brain injury, and ventriculoperitoneal shunt malfunction or infection; 75.9% of the hospitals cared for ≤100 EVDs annually. In Thailand, nonantimicrobial EVD catheters (98.3%) were used most often. Most hospitals (56.9%) did not routinely sample the cerebrospinal fluid. Prophylactic daily antibiotic use was prevalent (62.1%). Most hospitals (77.6%) did not measure the intracranial pressure during intrahospital transport. EVD infection was a commonly (69%) tracked QI measure; however, up to one third of the hospitals did not track any EVD QI measure. Most hospitals (94.8%) had no written EVD insertion and maintenance protocols. Most hospitals (79.3%) reported an EVD infection rate of ≤5% in the previous year. The low EVD infection rate, high cost, and/or the lack of equipment could account for the low usage of antimicrobial catheters and intracranial pressure monitoring. CONCLUSIONS: The results of the present study have identified QI opportunities in EVD management in Thailand. The development of an EVD-related QI process, reliable tracking of EVD infection rates, adaptation of U.S. guidelines to create standardized EVD protocols, and examination of the association between EVD practices and clinical outcomes in low-to middle-income countries are urgently needed.

OBJECTIVE/BACKGROUND: The natural history and the outlook of patients with hydrocephalus are dramatically affected using cerebrospinal fluid shunts. The several issues related with a long-standing shunt should suffice to justify all the possible attempts to free the patient from it. This study focused on the role of secondary endoscopic third ventriculostomy (ETV) in the achievement of shunt removal in cases of shunt malfunction, and to identify patients who could benefit most from the procedure. METHODS: In the period of 2006-2015, ETV was attempted in 47 patients >6 months old with ventriculoperitoneal shunt malfunction who presented with increased ventricle size compared with the previous neuroradiological examinations; simultaneously the shunt was removed or ligated. RESULTS: The overall success rate of secondary ETV was 74% (shunt-free patients with normalized intracranial pressure and absence of symptoms attributable to hydrocephalus) in patients with a long shunt duration (up to 30 years). The number of previous shunt revision procedures (P = 0.026) and lower age (P = 0.017) correlate with the likelihood of secondary ETV failure, a score of 80 as ETV success score (calculated for both pediatric and adult patients, even if the score was meant for the pediatric population) correlates with secondary ETV success (P = 0.014). CONCLUSIONS: Many patients with shunt malfunction can benefit from secondary ETV even after decades of shunting. Age at secondary ETV, the number of previous shunt revisions, and the ETV success score can help to better identify the best candidates for the procedure.

BACKGROUND/OBJECTIVE: Infection is the most common complication of external ventricular drain (EVD) placement. National trends in the annual incidence of meningitis among patients with traumatic brain injury (TBI) who have undergone EVD placement have not been reported. METHODS: The Nationwide Inpatient Sample was used to select adults with a primary diagnosis of TBI who underwent EVD placement between 2002 and 2011. Annual rates of meningitis among patients who underwent EVD placement were determined. We also calculated mortality rates and length of stay (LOS). Potential factors associated with meningitis were evaluated in a binary logistic regression analysis. RESULTS: Out of 1,571,927 adult discharges with a primary diagnosis of TBI between 2002 and 2011, 39,029 (2.5%) underwent EVD placement. Of these, 1544 (4.3%) patients developed meningitis. There was no significant trend in the annual incidence of meningitis (p = 0.88), mortality (p = 0.55), or mean LOS (p = 0.13) during the study period. Meningitis and mortality rates remained stable when stratifying patients by hospital volume. In the binary logistic regression, acquired immunodeficiency syndrome, sepsis, and cerebrospinal fluid leak were associated with meningitis. CONCLUSIONS: The incidence of meningitis in patients who underwent EVD placement remained stable between 2002 and 2011. Further prospective studies are needed to identify approaches for preventing these infections.

BACKGROUND/OBJECTIVE: Early mobilization of critically ill patients has been shown to improve functional outcomes. Neurosurgery patients with an external ventricular drain (EVD) due to increased intracranial pressure often remain on bed rest while EVD remains in place. The prevalence of mobilizing patients with EVD has not been described, and the literature regarding the safety and feasibility of mobilizing patients with EVDs is limited. The aim of our study was to describe the outcomes and adverse events of the first mobilization attempt in neurosurgery patients with EVD who participated in early functional mobilization with physical therapy or occupational therapy. METHODS: We performed a single-site, retrospective chart review of 153 patients who underwent placement of an EVD. Hemodynamically stable patients deemed appropriate for mobilization by physical or occupational therapy were included. Mobilization and activity details were recorded. RESULTS: The most common principal diagnoses were subarachnoid hemorrhage (61.4%) and intracerebral hemorrhage (17.0%) requiring EVD for symptomatic hydrocephalus. A total of 117 patients were mobilized (76.5%), and the median time to first mobilization after EVD placement in this group of 117 patients was 38 h. Decreased level of consciousness was the most common reason for lack of mobilization. The highest level of mobility on the patient's first attempt was ambulation (43.6%), followed by sitting on the side of the bed (30.8%), transferring to a bedside chair (17.1%), and standing up from the side of the bed (8.5%). No major safety events, such as EVD dislodgment, occurred in any patient. Transient adverse events with mobilization were infrequent at 6.9% and had no permanent neurological sequelae and were mostly headache, nausea, and transient diastolic blood pressure elevation. CONCLUSION: Early progressive mobilization of neurosurgical intensive care unit patients with external ventricular drains appears safe and feasible.

OBJECTIVEThe goal of this study was to clarify the long-term outcome of endoscopic third ventriculostomy (ETV) in pediatric hydrocephalus in light of the ETV Success Score (ETVSS), shunt dependency, and intellectual development.METHODSThe authors retrospectively analyzed pediatric patients with hydrocephalus who underwent ETV between 2002 and 2012 and who were followed for longer than 5 years as a single-center cohort. The data of the patients' pre- and postoperative status were collected. The relationships between ETVSS and the full-scale IQ as well as shunt dependency were analyzed. The usefulness of ETVSS for repeat ETV and the change of radiological parameters of ventricle size before and after ETV were also analyzed. The success of ETV was defined as no requirement for further CSF diversion procedures.RESULTSFifty ETVs were performed in 40 patients. The average ETVSS was 61 and the success rate at 6 months was 64%. The mean follow-up was 9.9 years (5.2-15.3 years), and the long-term success rate of ETV was 50%. The Kaplan-Meier survival curve continued to show a statistically significant difference among patients with a low, moderate, and high ETVSS, even after 6 months (p = 0.002). After 15 months from the initial ETV, no patients required additional CSF diversion surgery. There was no statistical significance between ETVSS and the long-term full-scale IQ or shunt dependency (p = 0.34 and 0.12, respectively). The radiological improvement in ventricle size was not associated with better future educational outcome.CONCLUSIONSThe ETVSS was correlated with the long-term success rate. After 15 months from the initial ETV, no patients required an additional CSF diversion procedure. The ETVSS was not considered to be correlated with long-term intellectual status.

OBJECTIVEAlthough endoscopic third ventriculostomy (ETV) for the treatment of hydrocephalus was introduced in 1923, the method was relegated to the sidelines in favor of extracranial techniques. Since the 1990s to the beginning of the current century, however, ETV has undergone a remarkable resurgence to become the first-line treatment for obstructive hydrocephalus, and for some groups, the procedure has been applied for communicating hydrocephalus as well. In the present study, the authors identified the top 50 cited ETV works. These articles represent works of significance that document current practices and provide guidance for future inquiry.METHODSThe top 50 cited articles pertaining to ETV were identified using bibliometric data obtained with the Harzing's Publish or Perish software search engine. These high-impact works were evaluated for publication properties including year, country of authorship, category, and journal.RESULTSThe top 50 works were cited an average of 141.02 times with a mean of 9.45 citations per year. Articles published in 2005 were the most numerous in the top 50 group. These top articles were most frequently published in the Journal of Neurosurgery: Pediatrics. Most of the articles were clinical studies reporting on patients in the pediatric age group. The country of most authorship was the US, although many other countries were among the top 50 works.CONCLUSIONSThe present report discusses the bibliometric analysis of the top 50 ETV articles. This list may be useful to those interested in the progress and current status of this procedure.

BACKGROUND: In the current dynamic health environment, increasing number of procedures are being completed by advanced practitioners (nurse practitioners and physician assistants). This is the first study to assess the clinical outcomes and safety of external ventricular drain (EVD) placements by specially trained advanced practitioners. OBJECTIVE: Compare the safety and outcomes of EVD placement by advanced practitioners in patients with subarachnoid hemorrhage (SAH). METHODS: A cohort comparison study was performed from an aneurysmal SAH database selecting patients treated with EVD from a single major academic institution in the USA between June 2007 and June 2017. Safety, accuracy, and complications of EVD placement were compared between advanced practitioners and neurosurgical physicians (attending neurosurgeon and subspecialty clinical fellow). Statistical analysis was performed using the Mann-Whitney test for continuous variables and χ2 test for categorical variables, with p values set at < 0.05 for significance. RESULTS: We identified 203 patients for this cohort with 238 EVD placements; eighty-seven (36.6%) placements were performed by advanced practitioners and 151 (63.4%) by neurosurgeons. Most of the ventriculostomies were placed in the emergency room (n = 114; 47.9%). Additional procedures performed concurrently with the EVD placements were significantly higher among the physicians' group (21.8 vs. 4.6%; p < 0.001). Bedside placement and usage of Ghajar guide were significantly higher among advanced practitioner's (58.3 vs. 98.9 and 9.9 vs. 64.4%, respectively, with a p < 0.001 for both). There were, however, no significant differences in terms of the number of attempts for insertion, intraprocedural complications, tract hemorrhages, accuracy, infection rates, catheter dislodgments, and need for repositioning/replacement of EVD. CONCLUSION: After appropriate training, EVD placement can be safely performed by advanced practitioners with an adequate accuracy of placement.

BACKGROUND: Pediatric hydrocephalus is a health burden for East African countries, with an estimated incidence of 6000 new cases per year. The objective of this study is to describe the epidemiology and surgical outcomes of patients treated for pediatric hydrocephalus in the single neurosurgical center of Zanzibar. METHODS: From December 2016 to December 2017, we prospectively collected data on all patients admitted with the diagnosis of hydrocephalus. Information was gathered regarding demographics, maternal health, preoperative imaging, surgical procedures, and postsurgical complications. RESULTS: We collected data on 63 patients. Average age was 203 days, and gender was 49.2% female and 50.8% male. All mothers of patients attended an antenatal clinic for routine screening during pregnancy. Folic acid prophylaxis was used by 9.5% of the mothers during pregnancy. At the first visit, 46.0% of patients presented with signs of infection, 20.6% with congenital abnormalities, and 20.6% with seizures. Regarding etiology of hydrocephalus, 22.2% of all cases were uncertain; 20.6% were associated with neural tube defects; 39.7% were postinfectious hydrocephalus; 3.2% were aqueduct stenosis; 4.8% were associated with brain tumor; and 9.6% were malformative. We performed 7 endoscopic third ventriculostomies and placed 40 ventriculoperitoneal shunts. The complication rate at follow-up was 12.5%. CONCLUSIONS: It seems that hydrocephalus in Zanzibar has similar causes, progression, and complication rates to previous reports from other African hospitals. Further studies of postinfectious hydrocephalus need to be conducted because recent findings suggest that it is a potentially preventable cause of the disease.

BACKGROUND: Ventriculostomy using the freehand pass method is subject to complications arising from misplacement of the catheter tip. This method may require multiple passes for successful catheterization. Methods of determining the burr-hole location (known as the Kocher point) were derived historically from European patients and may not be appropriate for other populations with different cranial shapes. This study examines the possibility that anatomic variation in interpopulation variation together with sexual dimorphism in cranial size and shape may contribute to this problem. METHODS: Sagittal and parasagittal measurements of the frontal bone were taken of 300 Thai (150 female, 150 male) crania and 300 American white (150 female, 150 male) crania. These measurements were compared to determine sexual dimorphism and interpopulation variation in size and shape. RESULTS: The measurements were statistically significantly larger in males than in females and on the right side than the left in both sexes in both Thai and American white samples. The frontal bone is significantly longer at the sagittal plane in Europeans of both sexes than in Thai, but in the parasagittal plane, there is no difference. This finding indicates a difference in frontal bone shape between the 2 populations and between males and females. CONCLUSIONS: The dimensions of the frontal bone vary between males and females and can vary among populations. The optimal location for the burr hole in freehand pass ventriculostomy may depend on both the gender and the ancestry of the patient.

BACKGROUND: Spontaneous intracerebral hemorrhage is a disease with high morbidity and mortality. Extension of the hemorrhage into the ventricles is associated with the development of acute hydrocephalus and a poor outcome. Although it can be managed by external ventricular drainage (EVD), a subset of these patients require placement of permanent ventricular shunts. This study aimed to examine the factors on admission that can predict shunt dependency after EVD management. METHODS: Seventy-two patients who underwent EVD were included in this study. Seventeen of these patients underwent placement of a ventriculoperitoneal shunt. Variables analyzed included age, intraventricular hemorrhage (IVH) score, bicaudate index, acute hydrocephalus, initial Glasgow Coma Scale scores, and blood volume in each ventricle. RESULTS: In univariate analysis, IVH score (p = 0.020), bicaudate index (p < 0.001), blood volume in lateral ventricles (p = 0.025), blood volume in the fourth ventricle (p = 0.038), and the ratio of blood volume in lateral ventricles to that in third and fourth ventricles (p = 0.003) were significantly associated with persistent hydrocephalus. The best multiple logistic regression model included blood volume parameters and bicaudate index as predictors with the area under a receiver operating characteristic curve of 0.849. The variance inflation factor (VIF) showed that collinearity was not found among predictors. Patients diagnosed with acute hydrocephalus had less blood volume in the lateral ventricles (OR = 0.910) and had more blood volume in the third ventricle (OR = 3.174) and fourth ventricle (OR = 2.126). CONCLUSIONS: These findings may promote more aggressive monitoring and earlier interventions for persistent hydrocephalus after intraventricular hemorrhage in patients at risk.

The aim of this study is to evaluate the clinical history and prognosis of children with early-onset hydrocephalus. The retrospective study's inclusion criteria were hydrocephalus diagnosis before the age of 5 years, independent of aetiology, and birth details, January 1, 2000 to December 31, 2014. Overall, 142 children were entered into the study, divided into 11 aetiological groups: premature-birth post-intraventricular haemorrhage (16%), brain tumours (16%), spina bifida (15%), aqueductal stenosis (8%), post-meningitis (8%), post-haemorrhage (8%), Dandy-Walker malformation (6%), unknown origin (6%), arachnoid cyst (5%), miscellaneous obstruction (4%), and various causes (8%). In total, 23 patients died, primarily from the tumour group. Ventriculostomy, performed 42 times, was successful in 20 patients. Overall, 226 internal shunts were placed in 99 children. Infectious complications affected 19% of children after shunt placement and 51% after mechanical complications. Mean follow-up was 4 years 10 months, with 61% of children progressing fairly well, especially those with aqueductal stenosis, cysts, and unknown or diverse obstructive causes. Post-meningitis hydrocephalus displayed the poorest outcome. Isolated obstructive hydrocephalus exhibited better prognosis, with most obstructive aetiologies effectively treated via ventriculostomy. Children treated by shunt placement were more at risk of complications. Aetiologies with associated abnormalities and neurological sequelae had poorer outcomes.

BACKGROUND: Incidence of catheter tract hemorrhage (CTH) after initial ventriculostomy placement ranges from 10 to 34%. We investigated CTH incidence in the Clot Lysis: Evaluation of Accelerated Resolution of Intraventricular Hemorrhage Phase III trial. METHODS: Prospective observational analysis of 1000 computer tomography (CT) scans from all 500 patients enrolled in the trial. All catheters were evaluated on first CT post-placement and on last CT prior to randomization for placement location and CTH size, location, and severity. Clinical variables were assessed for association with CTH with multivariable logistic regression. RESULTS: Of 563 catheters, CTH was detected in 14 and 21% of patients on first and last CT (median 3.7 and 43.4 h after catheter placement, respectively). All, but one were asymptomatic. Majority of CTH (86%) occurred within 24 h after placement, were located within 1 cm of the skull, and had at least one diameter > 5 mm. Most catheters (71%) terminated in the third or lateral ventricle ipsilateral to insertion site. Factors significantly associated with CTH were pre-admission use of antiplatelet drugs, accuracy of catheter placement, non-operating room catheter placement, Asian race, and intraventricular hemorrhage expansion. CONCLUSIONS: CTH incidence on initial catheter placement and during stabilization was relatively low, despite emergent placement in a high-risk population. Catheter placement accuracy was similar or better than convenience samples from the published literature. Decreasing risk of CTH may be achieved with attention to catheter placement accuracy and placement in the operating room. Antiplatelet agent use was an independent risk factor for CTH.

BACKGROUND: Endoscopic third ventriculostomy (ETV) has become one of the most common neuroendoscopic procedures. METHODS: In this article, we will review the major milestones in the history of ETV development from its early use by Walter Dandy to the techniques currently employed with advanced technology. CONCLUSIONS: ETV has become an important technique in the armamentarium of the neurosurgeon. From a meager beginning with few applications, our knowledge of long-term outcomes has evolved. ETV has a rich history and more recently, has had a renewed interest in its use. Our current understanding of its indications is growing and is based on a century of development through trial and error.

BACKGROUND: Patients with aneurysmal subarachnoid hemorrhage (SAH) often develop hydrocephalus requiring an external ventricular drain (EVD). The best available evidence suggests that a rapid EVD wean and intermittent CSF drainage is safe, reduces complications, and shortens ICU and hospital length of stay as compared to a gradual wean and continuous drainage. However, optimal EVD management remains controversial and the baseline practice among neurological ICUs is unclear. Therefore, we sought to determine current institutional practices of EVD management for patients with aneurysmal SAH. METHODS: An e-mail survey was sent to attending intensivists and neurosurgeons from 72 neurocritical care units that are registered with the Neurocritical Care Research Network or have been previously associated with the existing literature on the management of EVDs in critically ill patients. Only one response was counted per institution. RESULTS: There were 45 out of 72 institutional responses (63%). The majority of responding institutions (80%) had a single predominant EVD management approach. Of these, 78% favored a gradual EVD weaning strategy. For unsecured aneurysms, 81% kept the EVD continuously open and 19% used intermittent drainage. For secured aneurysms, 94% kept the EVD continuously open and 6% used intermittent drainage. Among continuously drained patients, the EVD was leveled at 18 (unsecured) and 11 cm H2O (secured) (p < 0.0001). When accounting for whether the EVD strategy was to enhance or minimize CSF drainage, there was a significant difference in the management of unsecured versus secured aneurysms with 42% using an enhance drainage approach in unsecured patients and 92% using an enhance drainage approach in secured patients (p < 0.0001). CONCLUSION: Most institutions utilize a single predominant EVD management approach, with a consensus toward a continuously open EVD to enhance CSF drainage in secured aneurysm patients coupled with a gradual weaning strategy. This finding is surprising given that the best available evidence suggests that the opposite approach is safe and can reduce ICU and hospital length of stay. We recommend a critical reassessment of the approach to the management of EVDs. Given the potential impact on patient outcomes and length of stay, more research needs to be done to reach a threshold for practice change, ideally via multicenter and randomized trials.

OBJECTIVE: To describe long-term outcomes of endoscopic third ventriculostomy (ETV) in adults with hydrocephalus. METHODS: Single-institution retrospective review of adults treated with ETV between 1998 and 2006. Patient demographic, treatment, and follow-up data were collected. The patients were divided into 2 groups: primary ETV for patients with previously untreated or newly diagnosed hydrocephalus and secondary ETV for patients with a previous shunt presenting with shunt malfunction. ETV outcome was deemed successful if the patient remained shunt-free after ETV. Multivariate analysis was performed using Cox regression. RESULTS: The study population comprised 190 patients, with a median age of 43 years (range, 16-79 years). The median duration of follow-up was 112 months (range, 1-190 months). The primary ETV group contained 129 patients; the secondary ETV group, 61 patients. Operative complications occurred in 11 patients (6%). A successful outcome was obtained in 139 patients (73%). ETV failure occurred in 51 patients, with a median time to failure of 2 months (range, 0-124 months). Although the majority (86%) of ETV failures occurred within 2 years postoperatively, failure was noted in 3 cases between 5 and 10 years after intervention, including in 1 patient at a 124-month follow-up. In multivariate analysis, only previous shunt was found to influence outcomes (P = 0.021), with shorter ETV survival noted in patients with a previous shunt. Age, indication, and ETV success did not influence outcome. CONCLUSIONS: ETV is a safe procedure with excellent rates of long-term efficacy; however, late failure can occur, and patients should be instructed to seek medical advice if symptoms recur. A previous shunt is associated with a higher ETV failure rate.

BACKGROUND: Severe traumatic brain injury is associated with a multi-systemic response and changes in metabolic demand. Patients requiring intracranial pressure monitoring or cerebrospinal fluid diversion, often signifies a greater severity of injury. For this group, the association between RBC transfusion, transfusion thresholds, and clinical recovery is unknown. In this study, we studied the association between transfusion and clinical recovery for severe traumatic brain injury patients requiring external ventricular drain or intracranial pressure monitor placement. METHODS: Eighty-nine patients with a primary diagnosis of traumatic brain injury requiring implantation of either an intracranial pressure monitor or external ventricular drainage device were identified. All patients were managed in a Level 1 Trauma facility by board-certified neuro-intensive care practitioners for the course of their intensive care unit duration. The correlation between transfusion and clinical recovery, defined by change in Glasgow Coma Scale was assessed. RESULTS: Thirty-four patients required surgical decompression, and 56.18 % of the cumulative cohort were transfused during admission. Overall, transfusion was not associated with significant clinical recovery (change in GCS > 3) for Hgb threshold of 7 mg/dL (<3, 29.03 vs. ≥3, 37.93 %; p = 0.49), nor for higher stratifications (8 mg/dL, p = 0.63; 9 mg/dL, p = 0.79, 10 mg/dL, p = 1). For patients who required transfusions at thresholds ≥8 mg/dL, there was a positive association with decreased length of hospitalization, [p = 0.01; <8 mg/dL: 22 (12-33), ≥8 mg/dL: 14 (7.75-20)] [median (IQR)]. Similarly, length of ICU stay was shorter for patients transfused at thresholds ≥9 mg/dL, (p = 0.02). CONCLUSIONS: From our studies, we demonstrate no significant clinical benefit associated with stratified transfusion goals; however, there was a decrease in length of hospitalization for patients with transfusion thresholds of Hgb ≥ 8 mg/dL. Larger, randomized controlled trials may be required to more accurately assess outcomes in this patient population. In patients admitted for primary severe traumatic brain injury, we demonstrate no significant clinical benefit associated with stratified transfusion goals; however, there was a noticeable decrease in length of hospitalization for patients with transfusion thresholds of Hgb ≥ 8 mg/dL. Larger, randomized controlled trials may be required to more accurately assess outcomes in this patient population.
