Abstract
PURPOSE Placement of an external ventricular drainage (EVD) is one of the most frequent procedures in neurosurgery, but it has specific challenges and risks in the pediatric population. We here investigate the indications, management, and shunt conversion rates of an EVD. METHODS We retrospectively analyzed the data of a consecutive series of pediatric patients who had an EVD placement in the Department of Neurosurgery at Hannover Medical School over a 12-year period. A bundle approach was introduced to reduce infections. Patients were categorized according to the underlying pathology in three groups: tumor, hemorrhage, and infection. RESULTS A total of 126 patients were included in this study. Seventy-two were male, and 54 were female. The mean age at the time of EVD placement was 5.2 ± 5.0 years (range 0-17 years). The largest subgroup was the tumor group (n = 54, 42.9%), followed by the infection group (n = 47, 37.3%), including shunt infection (n = 36), infected Rickham reservoir (n = 4), and bacterial or viral cerebral infection (n = 7), and the hemorrhage group (n = 25, 19.8%). The overall complication rate was 19.8% (n = 25/126), and the total number of complications was 30. Complications during EVD placement were noted in 5/126 (4%) instances. Complications during drainage time were infection in 9.5% (12 patients), dysfunction in 7.1% (9 patients), and EVD dislocation in 3.2% (4 patients). The highest rate of complications was seen in the hemorrhage group. There were no long-term complications. Conversion rates into a permanent shunt system were 100% in previously shunt-dependent patients. Conversion rates were comparable in the tumor group (27.7%) and in the hemorrhage group (32.0%). CONCLUSION EVD placement in children is an overall safe and effective option in children. In order to make further progress, carefully planned prospective and if possible randomized studies are needed controlling for multivariable aspects.

Postprocedural Complications of External Ventricular Drains: A Meta-Analysis Evaluating the Absolute Risk of Hemorrhages, Infections, and Revisions. World Neurosurg 2023; 171:41-64.

Abstract
BACKGROUND External ventricular drain (EVD) insertion is often a lifesaving procedure frequently used in neurosurgical emergencies. It is routinely done at the bedside in the neurocritical care unit or in the emergency room. However, there are infectious and noninfectious complications associated with this procedure. This meta-analysis sought to evaluate the absolute risk associated with EVD hemorrhages, infections, and revisions. The secondary purpose was to identify and characterize risk factors for EVD complications. METHODS We searched the MEDLINE (PubMed) database for "external ventricular drain," "external ventricular drain" + "complications" or "Hemorrhage" or "Infection" or "Revision" irrespective of publication year. Estimates from individual studies were combined using a random effects model, and 95% confidence intervals (CIs) were calculated with maximum likelihood specification. To investigate heterogeneity, the t2 and I2 tests were utilized. To evaluate for publication bias, a funnel plot was developed. RESULTS There were 260 total studies screened from our PubMed literature database search, with 176 studies selected for full-text review, and all of these 176 studies were included in the meta-analysis as they met the inclusion criteria. A total of 132,128 EVD insertions were reported, with a total of 130,609 participants having at least one EVD inserted. The pooled absolute risk (risk difference) and percentage of the total variability due to true heterogeneity (I2) for hemorrhagic complication was 1236/10,203 (risk difference: -0.63; 95% CI: -0.66 to -0.60; I2: 97.8%), infectious complication was 7278/125,909 (risk difference: -0.65; 95% CI: -0.67 to -0.64; I2: 99.7%), and EVD revision was 674/4416 (risk difference: -0.58; 95% CI: -0.65 to -0.51; I2: 98.5%). On funnel plot analysis, we had a variety of symmetrical plots, and asymmetrical plots, suggesting no bias in larger studies, and the lack of positive effects/methodological quality in smaller studies. CONCLUSIONS In conclusion, these findings provide valuable information regarding the safety of one of the most important and most common neurosurgical procedures, EVD insertion. Implementing best-practice standards is recommended in order to reduce EVD-related complications. There is a need for more in-depth research into the independent risk factors associated with these complications, as well as confirmation of these findings by well-structured prospective studies.

Childs Nerv Syst 2022; 38:239-252. [PMID: 35022855 DOI: 10.1007/s00381-021-05400-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2021] [Accepted: 10/19/2021] [Indexed: 11/03/2022]
Abstract
INTRODUCTION Premature neonates have a high risk of intraventricular hemorrhage (IVH) at birth, the blood products of which activate inflammatory cascades that can cause hydrocephalus and long-term neurological morbidities and sequelae. However, there is no consensus for one treatment strategy. While the mainstay of treatment involves CSF diversion to reduce intracranial pressure, a number of interventions focus on blood product removal at various stages including extraventricular drains (EVD), intra-ventricular thrombolytics, drainage-irrigation-fibrinolytic therapy (DRIFT), and neuroendoscopic lavage (NEL). METHODS We performed a systematic review and meta-analysis to compare the risks and benefits commonly associated with active blood product removal treatment strategies. We searched MEDLINE, Embase, Scopus, Cochrane Library, and CINAHL databases through Dec 2020 for articles reporting on outcomes of EVDs, thrombolytics, DRIFT, and NEL. Outcomes of interest were rate of conversion to ventriculoperitoneal shunt (VPS), infection, mortality, secondary hemorrhage, and cognitive disability. RESULTS Of the 10,398 articles identified in the search, 23 full-text articles representing 22 cohorts and 530 patients were included for meta-analysis. These articles included retrospective, prospective, and randomized controlled studies on the use of EVDs (n = 7), thrombolytics (n = 8), DRIFT therapy (n = 3), and NEL (n = 5). Pooled rates of reported outcomes for EVD, thrombolytics, DRIFT, and NEL for ventriculoperitoneal shunt (VPS) placement were 51.1%, 43.3%, 34.3%, and 54.8%; for infection, 15.4%, 12.5%, 4.7%, and 11.0%; for mortality, 20.0%, 11.6%, 6.0%, and 4.9%; for secondary hemorrhage, 5.8%, 7.8%, 20.0%, and 6.9%; for cognitive impairment, 52.6%, 50.0%, 53.7%, and 50.9%. Meta-regression using type of treatment as a categorical covariate showed no effect of treatment modality on rate of VPS conversion or cognitive disability. CONCLUSION There was a significant effect of treatment modality on secondary hemorrhage and mortality; however, mortality was no longer significant after adjusting for year of publication. Re-hemorrhage rate was significantly higher for DRIFT (p < 0.001) but did not differ among the other modalities. NEL also had lower mortality relative to EVD (p < 0.001) and thrombolytics (p = 0.013), which was no longer significant after adjusting for year of publication. Thus, NEL appears to be safer than DRIFT in terms of risk of hemorrhage, and not different than other blood-product removal strategies in terms of mortality. Outcomes-in terms of shunting and cognitive impairment-did not differ. Later year of publication was predictive of lower rates of mortality, but not the other outcome variables. Further prospective and randomized studies will be necessary to directly compare NEL with other temporizing procedures.

[PMID: 34973652 DOI: 10.1016/j.clineuro.2021.107100] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 10/10/2021] [Accepted: 12/15/2021] [Indexed: 11/03/2022]
Abstract
BACKGROUND Since external ventricular drainage (EVD) related infections are usually due to skin flora, an extradural intra/extra-cranial accessory device, developed for pediatric patients under three years of age undergoing EVD positioning, is described. The aim of this paper is to provide technical description of this device, underlining the possibility to reduce infective risk and to prevent EVD dislocation. METHODS Patients undergoing A-D device EVD placement between 1990 and 2017 at authors' institution were retrospectively considered. The device was made of a fully MRI-compatible inert material (Ketron-Peek-1000), composed of two pieces securely fixable to the skull, bridging the catheter directly from the epidural space to the extracranial space without letting it come in contact with the skin. RESULTS A total number of 350 patients were considered. The mean age was 1.4 years, being the youngest patient a newborn of 25 weeks of gestational age. Mean time of EVD maintenance was 45 days, ranging from 21 to 81 days. 2 cases (0.6%) of EVD related infections were reported, while, pull-out of the ventricular catheter occurred in 3 cases (0.9%). No cases of bone fractures related to the clamp effect provided by A-D device were reported in the series CONCLUSIONS: This device could represent a safe and feasible option to reduce EVD related infections and catheter pull-out in pediatric patients. The encouraging results could strength the aim of the device to allow safer and longer length of CSF drainage. Moreover, the fully MRI-compatible nature and its non-magnetic properties allow to use it with neuronavigation systems.

Abstract
The management of post-infective hydrocephalus in infants remains a challenging task for the pediatric neurosurgeon. The decision-making curve is often complex in that appropriate temporizing measures need to be implemented to properly clear any infection within the CSF before any decision can be made regarding a permanent solution. The etiology differs at varying stages of neonatal development, and the weight of the child, skin fragility, and relevant surgical treatment options are often important limiting factors. Deciding on the optimal treatment option involves assessing the etiology, age, and clinical and radiological features of the individual case and selecting the most appropriate surgical option.

External ventricular drainage for posthemorrhagic ventricular dilatation in preterm infants: insights on efficacy and failure. J Neurosurg Pediatr 2021; 28:563-571.

Abstract
OBJECTIVE The objective of this study was to describe the clinical and neuroradiological characteristics of a cohort of preterm infants who had undergone external ventricular drain insertion as a temporary measure to treat posthemorrhagic ventricular dilatation. In addition, the authors investigated the factors predicting permanent shunt dependency. METHODS The authors retrospectively reviewed the medical records of a cohort of preterm infants who had undergone external ventricular drain insertion at Gaslini Children's Hospital (Genoa, Italy) between March 2012 and February 2018. They also analyzed clinical characteristics and magnetic resonance imaging data, including diffusion- and susceptibility-weighted imaging studies, which were obtained before both catheter insertion and removal. RESULTS Twenty-eight infants were included in the study. The mean gestational age was 28.2 ± 2.7 weeks, and the mean birth weight was 1209 ± 476 g. A permanent ventriculoperitoneal shunt was inserted in 15/28 (53.6%) infants because of the failure of external ventricular drainage as a temporary treatment option. Compared with the shunt-free group, the shunt-dependent group had a significantly lower gestational age (29.3 ± 2.3 vs 27.2 ± 2.7 weeks, p = 0.035) and tended toward a lower birth weight (p = 0.056). None of the clinical and neuroradiological characteristics significantly differed between the shunt-free and shunt-dependent groups at the time of catheter insertion. As expected, ventricular parameters as well as the intraventricular extension of intracerebral hemorrhage, as assessed using the intraventricular hemorrhage score, were reportedly higher in the shunt-dependent group than in the shunt-free group before catheter removal. CONCLUSIONS External ventricular drainage is a reliable first-line treatment for posthemorrhagic hydrocephalus. However, predicting its efficacy as a unique treatment remains challenging. A lower gestational age is associated with a higher risk of posthemorrhagic hydrocephalus progression, suggesting that the more undeveloped the mechanisms for the clearance of blood degradation products, the greater the risk of requiring permanent cerebrospinal fluid diversion, although sophisticated MRI investigations are currently unable to corroborate this hypothesis.

Timing of Temporizing Neurosurgical Treatment in Relation to Shunting and Neurodevelopmental Outcomes in Posthemorrhagic Ventricular Dilatation of Prematurity: A Meta-analysis. J Pediatr 2021; 234:54-64.e20.

Abstract
OBJECTIVE To determine the relationship between timing of initiation of temporizing neurosurgical treatment and rates of ventriculoperitoneal shunt (VPS) and neurodevelopmental impairment in premature infants with post-hemorrhagic ventricular dilatation (PHVD). STUDY DESIGN We searched MEDLINE, EMBASE, CINAHL, Web of Science, the Cochrane Database of Systematic Reviews, and the Cochrane Center Register of Controlled Trials for studies that reported on premature infants with PHVD who underwent a temporizing neurosurgical procedure. The timing of the temporizing neurosurgical procedure, gestational age, birth weight, outcomes of conversion to VPS, moderate-to-severe neurodevelopmental impairment, infection, temporizing neurosurgical procedure revision, and death at discharge were extracted. RESULTS Sixty-two full-length articles and 6 conference abstracts (n = 2533 patients) published through November 2020 were included. Pooled rate for conversion to VPS was 60.5% (95% CI, 54.9-65.8), moderate-severe neurodevelopmental impairment 34.8% (95% CI, 27.4-42.9), infection 8.2% (95% CI, 6.7-10.1), revision 14.6% (95% CI, 10.4-20.1), and death 12.9% (95% CI, 10.2-16.4). The average age at temporizing neurosurgical procedure was 24.2 ± 11.3 days. On meta-regression, older age at temporizing neurosurgical procedure was a predictor of conversion to VPS (P < .001) and neurodevelopmental impairment (P < .01). Later year of publication predicted increased survival (P < .01) and external ventricular drains were associated with more revisions (P = .001). Tests for heterogeneity reached significance for all outcomes and a qualitative review showed heterogeneity in the study inclusion and diagnosis criteria for PHVD and initiation of temporizing neurosurgical procedure. CONCLUSIONS Later timing of temporizing neurosurgical procedure predicted higher rates of conversion to VPS and moderate-severe neurodevelopmental impairment. Outcomes were often reported relative to the number of patients who underwent a temporizing neurosurgical procedure and the criteria for study inclusion and the initiation of temporizing neurosurgical procedure varied across institutions. There is need for more comprehensive outcome reporting that includes all infants with PHVD regardless of treatment.

Abstract
OBJECTIVE The role of tunneling an external ventricular drain (EVD) more than the standard 5 cm for controlling device-related infections remains controversial. METHODS This is a randomized, double-blind, 3-arm controlled trial done in the Children's Medical Center in Tehran, Iran. Pediatric patients (< 18 years old) with temporary hydrocephalus requiring an EVD and no evidence of CSF infection or prior EVD insertion were enrolled. Patients were randomly assigned (1:1:1) into the following arms: 5-cm (standard; group A); 10-cm (group B); or 15-cm (group C) EVD tunnel lengths. The investigators, parents, and person performing the analysis were masked. The surgeon was informed of the length of the EVD by the monitoring board just before operation. Patients were followed until the EVD's fate was established. Infection rate and other complications related to EVDs were assessed. RESULTS A total of 105 patients were enrolled in three random groups (group A = 36, group B = 35, and group C = 34). The EVD was removed because there was no further need in most cases (67.6%), followed by conversion to a new EVD or ventriculoperitoneal shunt (15.2%), infection (11.4%), and spontaneous discharge without further CSF diversion requirement (5.7%). No statistical difference was found in infection rate (p = 0.47) or EVD duration (p = 0.81) between the three groups. No group reached the efficacy point sooner than the standard group (group B: hazard ratio 1.21, 95% CI 0.75-1.94, p = 0.429; group C: hazard ratio 1.03, 95% CI 0.64-1.65, p = 0.91). CONCLUSIONS EVD tunnel lengths of 5 cm and longer did not show a difference in the infection rate in pediatric patients. Indeed, tunneling lengths of 5 cm and greater seem to be equally effective in preventing EVD infection. Clinical trial registration no.: IRCT20160430027680N2 (IRCT.ir).

Abstract
BACKGROUND Intraventricular hemorrhage (IVH) is a rare cause of intracranial bleeding across all age groups, with dismal sequelae in most of the affected population. The reported data on IVH are numerous, with multiple levels of evidence. We performed a citation-based analysis to identify the most-cited reports on IVH. METHODS A thorough search of the Scopus database was conducted using "intraventricular hemorrhage" as the search keyword. The 100 most cited studies were stratified in descending order. The reports were reviewed in-depth and categorized accordingly. Bibliometric parameters of interest were obtained for analysis. RESULTS The most-cited studies had been published between 1927 and 2017. Most (n = 60) had been published between 1980 and 2000. The most-cited studies had received a total of 16,512 citations, with an average of 174 citations per report. Studies on pathogenesis were the most prolific, with 23 articles included. A total of 13 randomized controlled trials were identified. The top contributing country was the United States, with 67 reports. The leading institution was the Washington University School of Medicine in St. Louis, Missouri, with 11 studies. Pediatrics was the most active journal, with 20 studies. CONCLUSION The present collection of highly cited studies can aid in the understanding of chronological trends and could serve as an efficient guide to delineate the reports involved in the evidence-based practice of the management of IVH.

Abstract
Perinatal intraventricular hemorrhage (IVH) with or without development of posthemorrhagic hydrocephalus (PHH) in premature neonates may lead to severe neurological disability. Although the percentage of preterm infants developing IVH has been greatly reduced in the last three decades, increased survival of these very immature infants has meant that large IVH with subsequent PHH is still a serious unsolved problem. Early cerebrospinal fluid diversion as a temporizing measure or a permanent shunt is the treatment of choice. This review summarizes the surgical modalities, techniques, and their complications in the management of IVH and PHH in premature infants. Though there is no level-one evidence to support the superiority of any of the currently available managements in the initial treatment of PHH over others, this review aims to provide pediatric neurosurgeons a comprehensive understanding of the pros and cons of various surgical treatment modalities, focusing on the temporizing measures before the infants is heavy enough to undergo ventriculoperitoneal shunt insertion. Based on the patient's condition, the facility and man power of the institution with minimal complication rate, the pediatric neurosurgeons may choose the best initial approach for the management of IVH and PHH in premature infants.

Abstract
PURPOSE In this study, we investigate the occurrence rate of early shunt infection and malfunction in pediatric patients after converting an external ventricular drainage (EVD) to a ventriculo-peritoneal shunt (VPS) without replacing the ventricular catheter. METHODS Data was retrospectively reviewed for 17 pediatric patients (11 male (64.7%), mean age 7.5 years, range 0.25-15 years) who underwent 18 consecutive direct conversions of tunneled EVD to VPS without replacing the ventricular catheter between 2008 and 2017. In each case, the EVD was inserted in sterile fashion within the operating room and tunneled subcutaneously 5-7 cm away from the insertion site. Primary outcome measure was the occurrence of early (within 30 days) VPS infection or malfunction. The mean follow-up time was 56.8 months (±35.7 months). RESULTS The mean period of EVD before VPS placement was 9.0 days (±3.6 days, range 2-18 days). Five patients had shunt infections/malfunctions. One patient (5.6%) had an early shunt infection after 30 days. One patient had a late shunt infection after 9 months. One patient had an early shunt malfunction after 9 days. Two patients (11.1%) had late shunt malfunctions after 6.5 months and 9 years. There were no other incidents of shunt-related complications or shunt-related mortality. CONCLUSION In the pediatric population, the conversion of a tunneled EVD to a VPS without replacing the ventricular catheter can be safely done. Cranial entry is spared, while the rates of shunt infection and malfunction do not increase significantly.

Abstract
OBJECT External ventricular drains (EVDs) are regularly used in pediatric neurosurgery for diagnostic and therapeutic purposes. Hemorrhage caused by placing an EVD is a common complication noted in the adult literature. In the pediatric literature, on the other hand, only a few articles have assessed the risk of hemorrhage with placement, and none have reported the occurrence of hemorrhage with removal of an EVD. The authors investigated the incidence of hemorrhage with both placement and removal of the EVD in a pediatric population. METHODS After obtaining institutional review board approval, a comprehensive database was created to include all pediatric patients who required EVD placement between March 2008 and June 2014 at the authors' institution. A retrospective chart review was completed, and all imaging was reviewed for evidence of hemorrhage with placement and removal of the EVD. RESULTS During the designated time period, 73 EVDs were placed in 63 patients (ages 2 weeks-17 years). Indications for EVD placement were as follows: shunt infection/malfunction (21), tumor (12), hydrocephalus (18), hemorrhage (12), edema (4), trauma (1), and other (5). Hemorrhage with placement was noted in 5 of the 50 patients who underwent imaging, with a volume ranging from 0.48 cm3 to 7.7 cm3. Thirty-two patients had imaging after EVD removal, and 7 of these patients were noted to have hemorrhage (volume range 0.012 cm3 to 81.5 cm3). CONCLUSIONS The authors found the incidence of hemorrhage at EVD placement to be 10%, and the incidence of hemorrhage on EVD removal to be 21.9% in those patients who underwent imaging after each event. Although none of the hemorrhages were of obvious clinical significance, these data can be useful in decision making, and in discussing the risks of EVDs with the patient's family.

Abstract
BACKGROUND Post-haemorrhagic hydrocephalus (PHH), a potential consequence of grade II-IV germinal matrix haemorrhage, remains a significant problem in premature infants with long-term neurodevelopmental disabilities and high mortality rates. Early ventriculoperitoneal shunt (VPS) insertion is associated with a high failure rate and many complications; hence, temporising measures are always instituted until the infant is mature (age and/or weight) enough. METHODS We have reviewed the recently available literature on the usefulness and complications of the initial measures used in the treatment of PHH; particularly, focusing on serial cerebrospinal fluid (CSF) tapping, external ventricular drainage (EVD), ventriculosubgaleal shunts (VSG), ventricular access devices (VADs), endoscopic third ventriculostomy (ETV) with and without coagulation of the choroid plexus. RESULTS Randomised controlled trials (RCTs) have failed to demonstrate a significant effect of serial lumbar punctures on the rates of morbidity, mortality or conversion to permanent VPS in the treatment of PHH. Retrospective studies, mostly with small patients' numbers, provide not only a considerable controversy regarding EVD, VSG, VADs and ETV usefulness in the management of PHH but also variable rates on their complications. None of these variables have, however, been tested using RCTs. CONCLUSION There is no level-one evidence to support the superiority of any of the currently available temporising measures in the initial treatment of PHH over others. The need for such rigorous studies remains largely unmet. We feel that a UK multi-centre-RCT is paramount to provide neurosurgeons with the evidence needed to choose the best initial approach for PPH treatment, yet with minimal complications' rate.

Abstract
OBJECT The objective of this systematic review and analysis was to answer the following question: What are the optimal treatment strategies for posthemorrhagic hydrocephalus (PHH) in premature infants? METHODS Both the US National Library of Medicine and the Cochrane Database of Systematic Reviews were queried using MeSH headings and key words relevant to PHH. Two hundred thirteen abstracts were reviewed, after which 98 full-text publications that met inclusion criteria that had been determined a priori were selected and reviewed. RESULTS Following a review process and an evidentiary analysis, 68 full-text articles were accepted for the evidentiary table and 30 publications were rejected. The evidentiary table was assembled linking recommendations to strength of evidence (Classes I-III). CONCLUSIONS There are 7 recommendations for the management of PHH in infants. Three recommendations reached Level I strength, which represents the highest degree of clinical certainty. There were two Level II and two Level III recommendations for the management of PHH. Recommendation Concerning Surgical Temporizing Measures: I. Ventricular access devices (VADs), external ventricular drains (EVDs), ventriculosubgaleal (VSG) shunts, or lumbar punctures (LPs) are treatment options in the management of PHH. Clinical judgment is required. STRENGTH OF RECOMMENDATION Level II, moderate degree of clinical certainty. Recommendation Concerning Surgical Temporizing Measures: II. The evidence demonstrates that VSG shunts reduce the need for daily CSF aspiration compared with VADs. STRENGTH OF RECOMMENDATION Level II, moderate degree of clinical certainty. Recommendation Concerning Routine Use of Serial Lumbar Puncture: The routine use of serial lumbar puncture is not recommended to reduce the need for shunt placement or to avoid the progression of hydrocephalus in premature infants. STRENGTH OF RECOMMENDATION Level I, high clinical certainty. Recommendation Concerning Nonsurgical Temporizing Agents: I. Intraventricular thrombolytic agents including tissue plasminogen activator (tPA), urokinase, or streptokinase are not recommended as methods to reduce the need for shunt placement in premature infants with PHH. STRENGTH OF RECOMMENDATION Level I, high clinical certainty. Recommendation Concerning Nonsurgical Temporizing Agents. II. Acetazolamide and furosemide are not recommended as methods to reduce the need for shunt placement in premature infants with PHH. STRENGTH OF RECOMMENDATION Level I, high clinical certainty. Recommendation Concerning Timing of Shunt Placement: There is insufficient evidence to recommend a specific weight or CSF parameter to direct the timing of shunt placement in premature infants with PHH. Clinical judgment is required. STRENGTH OF RECOMMENDATION Level III, unclear clinical certainty. Recommendation Concerning Endoscopic Third Ventriculostomy: There is insufficient evidence to recommend the use of endoscopic third ventriculostomy (ETV) in premature infants with posthemorrhagic hydrocephalus. STRENGTH OF RECOMMENDATION Level III, unclear clinical certainty.

Abstract
OBJECTIVES Dysnatremia is common in critically ill children due to disruption of hormonal homeostasis. Children with brain injury are at risk for syndrome of inappropriate antidiuretic hormone, cerebral salt wasting, and sodium losses due to externalized ventricular drain placement. We hypothesized that among PICU patients managed with an externalized ventricular drain, hyponatremia is common, hyponatremia is associated with seizures and in-hospital mortality, and greater sodium fluctuations are associated with in-hospital mortality. DESIGN Retrospective observational study. SETTING Tertiary care PICU. PATIENTS All pediatric patients treated in the PICU with an externalized ventricular drain from January 2005 to December 2009. Patients were identified by searching the physician order entry database for externalized ventricular drain orders. Hyponatremia was defined as the minimum sodium during patients' externalized ventricular drain time and was categorized as mild (131-134 mEq/L) or moderate to severe (≤ 130 mEq/L). Magnitude of sodium fluctuation was defined as the difference between a patient's highest and lowest sodium during the time in which an externalized ventricular drain was in use (up to 14 d). Seizure was defined as a clinically evident convulsion during externalized ventricular drain presence. A priori confounders were age, history of epilepsy, and externalized ventricular drain indication. Multivariable regression was performed to test the association between sodium derangements and outcomes. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Three hundred eighty patients were eligible. One hundred nine (29%) had mild hyponatremia, and 30 (8%) had moderate to severe hyponatremia. Twenty-eight patients (7%) had a seizure while hospitalized. Eighteen patients died (5%) prior to discharge. Survivors had a median daily sodium fluctuation of 1 mEq/L [0-5] vs non-survivors 9 mEq/L [6-11] (p < 0.001) and a median sodium fluctuation of 5 mEq/L [2-8] vs non-survivors 15 mEq/L [9-24] (p < 0.001) during externalized ventricular drain management. After controlling for a priori covariates and potential confounders, hyponatremia was not associated with an increased odds of seizures or in-hospital mortality. However, greater fluctuations in daily sodium (odds ratio, 1.38; 95% CI, 1.06-1.8) and greater fluctuations in sodium during externalized ventricular drain management were associated with increased odds of in-hospital mortality (odds ratio, 1.59; 95% CI, 1.2-2.11). CONCLUSIONS Hyponatremia was common in PICU patients treated with externalized ventricular drains but not associated with seizures or in-hospital mortality. Greater sodium fluctuations during externalized ventricular drain management were independently associated with increased odds of in-hospital mortality.

Abstract
PURPOSE The aim of this study is to report the efficacy of long subcutaneous tunnelling of external ventricular drains in reducing rates of infection and catheter displacement in a paediatric population. METHODS In children requiring external ventricular drainage, a long-tunnelled drain was placed and managed according to a locally agreed guideline. End points were novel CSF infection incurred during the time of drainage and re-operation to re-site displaced catheters. Data were compared to other published series. RESULTS One hundred eighty-one long-tunnelled external ventricular drains (LTEVDs) were inserted. The mean age was 6.6 years (range 0-15.5 years). Reasons for insertion included intraventricular haemorrhage (47 %), infection (27 %), tumour-related hydrocephalus (7.2 %), as a temporising measure (17 %) and trauma (2.2 %). The overall new infection rate for LTEVD was 2.76 %. If the 48 cases where LTEVDs were inserted to treat an existing infection are excluded, the infection rate was 3.8 % (5/133). The mean duration of insertion was 10 days (range 0-42 days). Four LTEVDs (2.2 %) were inadvertently dislodged, requiring reinsertion. Thirteen patients required removal of EVD alone. There was a significant difference (p < 0.05) when comparing our infection rate to 14 publications of infection rates in short-tunnelled EVDs; however, there was no difference when comparing our data to three publications using LTEVDs. CONCLUSION The use of an antibiotic-impregnated LTEVD, managed according to a predefined guideline, is associated with significantly reduced infection and displacement rates when compared with contemporary series. It is suggested that this reduction is of both clinical and economic benefits.

Abstract
Intraventricular hemorrhage of prematurity (IVH) is a diagnosis that has become more frequent in recent years. Advances in medical care have led to survival of increasingly premature infants, as well as infants with more complex medical conditions. Treatment with a ventricular access device (VAD) was reported almost 3 decades ago; however, it is unclear how effective this treatment is in the current population of premature infants. At our institution (from 2004 to present), we treat posthemorrhagic hydrocephalus (PHH) with a VAD. In order to look at safety and efficacy, we retrospectively combed the medical records of premature children, admitted to Lucile Packard Children's Hospital from January 2005 to December 2009, and identified 310 premature children with IVH. Of these, 28 children required treatment for PHH with a VAD. There were no infections associated with placement of these devices and a very low rate of other complications, such as need for repositioning (7.41%) or replacement (3.75%). Our data show that treatment with a VAD is very safe, with few complications and can be used to treat PHH in this very complex infant population.

Abstract
Posthaemorrhagic hydrocephalus (PHH) is a major problem for premature infants, generally requiring lifelong care. It results from small blood clots inducing scarring within CSF channels impeding CSF circulation. Transforming growth factor – beta is released into CSF and cytokines stimulate deposition of extracellular matrix proteins which potentially obstruct CSF pathways. Prolonged raised pressures and free radical damage incur poor neurodevelopmental outcomes. The most common treatment involves permanent ventricular shunting with all its risks and consequences. This is a review of the current evidence for the treatment and prevention of PHH and shunt dependency. The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library) and PubMed (from 1966 to August 2008) were searched. Trials using random or quasi-random patient allocation for any intervention were considered in infants less than 12 months old with PHH. Thirteen trials were identified although speculative interventions were also evaluated. The literature confirms that lumbar punctures, diuretic drugs and intraventricular fibrinolytic therapy can have significant adverse effects and fail to prevent shunt dependence, death or disability. There is no evidence that postnatal phenobarbital administration prevents intraventricular haemorrhage (IVH). Subcutaneous reservoirs and external drains have not been tested in randomized controlled trials, but can be useful as a temporising measure. Drainage, irrigation and fibrinolytic therapy as a way of removing blood to inhibit progressive deposition of matrix proteins, permanent hydrocephalus and shunt dependency, are invasive and experimental. Studies of ventriculo-subgaleal shunts show potential as a temporary method of CSF diversion, but have high infection rates. At present no clinical intervention has been shown to reduce shunt surgery in these infants. A ventricular shunt is not advisable in the early phase after PHH. Evidence exists that pre-delivery corticosteroid therapy reduces mortality and IVH and there may be trends towards reduced disability in the short term. There is also evidence that postnatal indomethacin reduces IVH but with no effect on mortality or disability. Overall, there is still no definitive algorithm for the treatment of PHH or prevention of shunt dependence. New therapeutic approaches in neonatal care, including those aimed at pre-empting PHH, offer the best hope of improving neurodevelopmental outcomes.

Abstract
External ventricular drains (EVDs), like any surgically-implanted foreign body, are at risk of infection. We present the results of a completed audit loop following introduction of an evidence-based protocol for their insertion and management. There were two phases over a 2-year period. Phase 1 was a retrospective audit of our EVD infection rate. Phase 2 was a prospective audit of the infection rate subsequent to the introduction of a protocol for the insertion and management of EVDs. In phase 1, the infection rate was 27%. In phase 2, the infection rate was 12%. This was a statistically significant reduction (p < 0.05, Chi-squared test). EVD infection is unfortunately a common clinical problem and associated with potential morbidity and mortality. This study demonstrates that adherence to an evidence-based protocol for their insertion and management is associated with a significant reduction in the infection rate.

Abstract
OBJECTIVE The aim of this study is to retrospectively evaluate a series of consecutive patients affected by post-hemorrhagic hydrocephalus in prematurity, treated with an implant of an Ommaya reservoir followed by ventriculo-peritoneal (VP) shunt and/or endoscopic third ventriculostomy (ETV) to evaluate the safety and efficacy of these treatment options in the management of the condition. METHODS Between 2002 and 2005, 18 consecutive premature patients affected by intra-ventricular haemorrhage (IVH) grades II to IV, presenting with progressive ventricular dilatation, were operated for implant of an intra-ventricular catheter connected to a sub-cutaneous Ommaya reservoir. Cerebrospinal fluid was intermittently aspirated percutaneously by the reservoir according with the clinical requirements and the echographic follow-up. The patients who presented a progression of the ventricular dilatation were finally operated for VP shunt implant or ETV according with the MRI findings. RESULTS One patient had grade II, 5 had grade III, and 12 had grade IV IVH. The mean age at IVH diagnosis was 5.2 days; the mean age at reservoir implant was 17.3 days. The Ommaya reservoir was punctured on an average basis of 11.4 times per patient (range 2-25), and the mean interval between aspirations was 2.7 days. The mean CSF volume per tap was 20 ml. One patient died for pulmonary complications during the study period. Out of the 17 survivors, 3 did not develop progressive ventricular dilatation, and their reservoir was removed; 14 developed progressive hydrocephalus, 5 of whom were implanted with a VP shunt and 9 received an ETV. Amongst the five shunted patients, two were re-admitted for shunt malfunction and had their shunt removed after ETV after 6.1 and 20.5 months, respectively. Amongst the nine patients who received an ETV, five had to be re-operated for VP shunt implant at an average interval of 2.17 months (range 9-172 days) because of increasing ventricular dilatation. Two of them had a redo third ventriculostomy with shunt removal at 11 and 25.1 months, respectively, after insertion. The first was reimplanted with a VP shunt 4 days later; the second remains shunt free. Therefore, at the end of the follow-up period, 10 out of 17 children affected by post-hemorrhagic hydrocephalus in prematurity were shunt free (59%). CONCLUSIONS The combination of Ommaya reservoir, VP shunt, and the aggressive use of ETV as a primary treatment or as an alternative to shunt revision allowed for a significant reduction of shunt dependency in a traditionally shunt-dependent population. Further studies are warranted to optimise the algorithm of treatment in these patients.

Abstract
CASE REPORT We report a complicated extremely low-birth-weight (ELBW) infant with posthemorrhagic hydrocephalus after intraventricular hemorrhage and preceding stoma creation after bowel perforation who was treated with staged operations, including shunting and external ventricular drainage. The first operation was a temporary valveless ventriculoperitoneal (VP) shunt placement until the time of the stoma closure. The stoma was successfully closed 3 months after the first operation when the peritoneal tube was drawn out from the chest wall and the VP shunt system was temporarily used as an external drainage with a long subcutaneous tunnel. One month after the second operation, final VP shunt placement was performed after good healing of bowel anastomosis was surely confirmed. The previous peritoneal shunt tube was cut behind the ear, removed, and replaced with a valve-regulated VP shunt system. CONCLUSION This staged strategy is a safe and feasible option for complicated ELBW infants with preceding stoma and hydrocephalus.

Abstract
OBJECTIVE The early management of posthemorrhagic hydrocephalus in premature infants is challenging and controversial. These infants need a temporary cerebrospinal fluid (CSF) diversion procedure until they gain adequate weight, and the blood and protein levels in CSF are reasonably low before permanent shunt can be placed. Various options are available with their associated advantages and disadvantages. Ventriculosubgaleal shunts have been recommended as a more physiologic and less invasive means of achieving this goal. We have performed this procedure in 6 premature infants to evaluate their effectiveness and complications. METHODS Six consecutive premature infants with posthemorrhagic hydrocephalus underwent placement of ventriculosubgaleal shunts over a 1-year period of time. We reviewed their clinical and imaging progress to assess the ability of the shunt to control hydrocephalus and the complication rates. RESULTS In all 6 patients, the ventriculosubgaleal shunt controlled the progression of hydrocephalus as assessed by clinical and imaging parameters. A permanent shunt was avoided in 1 patient (16.6%). However, 4 patients developed shunt infections, 1 involving the ventriculosubgaleal shunt itself, and 3 immediately after conversion to ventriculoperitoneal shunt. The total infection rate of the series was 66.6%. All infections were caused by staphylococcus species. There was only a 1% shunt infection rate in our institution for all nonventriculosubgaleal shunts during the same period of time. CONCLUSION Placement of ventriculosubgaleal shunts for interim CSF diversion in neonates with posthemorrhagic hydrocephalus is effective as a temporary method of CSF diversion. However, our experience has shown that it is associated with a unacceptably high CSF infection rate. A potential cause for infection is CSF stasis just beneath the extremely thin skin of the premature infants, promoting colonization by skin flora. CSF sampling before conversion to a permanent shunt and replacement of the proximal hardware, which has been in situ for a prolonged period, may decrease the infection rates. At present, the procedure is no longer performed at our institution.

Abstract
Germinal matrix-intraventricular hemorrhage (GMH-IVH) in the premature newborn results from rupture of fragile capillaries in the germinal matrix. Its pathogenesis is multifactorial and relates principally to a pressure-passive cerebral circulation, fluctuations in cerebral blood flow, and derangements of coagulation and fragility of the germinal matrix microvasculature. Several interventions have beneficial effects for prevention of GMH-IVH. Outcome after GMH-IVH relates largely to the severity of hemorrhage, the extent of hemorrhagic and ischemic parenchymal involvement, and complications (e.g., posthemorrhagic hydrocephalus). Even in the absence of neuroimaging abnormalities, VLBW infants have a high incidence of academic and behavioral problems which persist into adolescence and early adulthood.
