Abstract
BACKGROUND AND OBJECTIVE Ventriculosubgaleal shunt (VSGS) was first described in 1896 by Von Mickulicz. It allows CSF to flow from the dilated ventricle to the subgaleal pouch developed in the scalp through a small silicon tube. The possibility that the hydrocephalic state in infants caused by hemorrhage/ + infection will only last a short while prompts the search for temporary management options, which must be a closed system in order to be more physiological given that these infants are frequently preterm (LBW) and immunologically immature. VSGS is one such option. To the best of our knowledge, most of the studies done on VSGS are retrospective, and there are very few prospective studies (none on Indian subjects till now). We aim to study the efficacy of VSGS in preventing the placement of VP Shunt in infants with post-hemorrhagic/post-infectious hydrocephalus. METHOD Our study (prospective observational) comprises 30 infants in whom VSGS was inserted at Sir Gangaram Hospital between August 2017 and October 2020 and who were followed up for 6 months after VSGS insertion. RESULT Most of the infants had a birth weight between 1501 and 2000 g with a mean gestational age of 31.2 weeks. Thirteen out of 30 patients did not require the placement of VP shunt. The rates were higher in the post-infectious group (50%) in contrary to the post hemorrhagic group where it was 38.8%. Complications encountered with VSGS include CSF leak (13.3%) and wound dehiscence (6.6%). None had VSGS blockage, migration, and infection. CONCLUSION We conclude that VSGS is a reliable, safe, easy to perform, and temporary treatment option in infants with post-hemorrhagic and post-infectious hydrocephalus and helps in avoiding VP shunt dependency in nearly half of them.

Abstract
OBJECTIVES To investigate the variability in diagnostic and therapeutic approaches to posthemorrhagic ventricular dilatation (PHVD) among Canadian neonatal centers, and secondary exploration of differences in approaches between Canadian and European practices. METHODS We conducted a survey among Canadian tertiary neonatal centers on their local practices for managing very preterm infants with PHVD. The survey covered questions on the diagnostic criteria, timing and type of interventions and resources utilization (transfer to neurosurgical sites and neurodevelopmental follow-up). In a secondary exploration, Canadian responses were compared with responses to the same survey from European centers. RESULTS 23/30 Canadian centers (77%) completed the survey. There was no consensus among Canadian centers on the criteria used for diagnosing PHVD or to initiate intervention. The therapeutic interventions also vary, both for temporizing procedures or permanent shunting. Compared to European practices, the Canadian approach relied less on the sole use of ultrasound criteria for diagnosing PHVD (43 vs 94%, p < 0.0001) or timing intervention (26 vs 63%, p = 0.007). Majority of European centers intervened early in the development of PHVD based on ultrasound parameters, whereas Canadian centers intervened based on clinical hydrocephalus, with fewer centers performing serial lumbar punctures prior to neurosurgical procedures (40 vs 81%, p = 0.003). CONCLUSION Considerable variability exists in diagnosis and management of PHVD in preterm infants among Canadian tertiary centers and between Canadian and European practices. Given the potential implications of the inter-center practice variability on the short- and long-term outcomes of preterm infants with PHVD, efforts towards evidence-based Canada-wide practice standardization are underway.

Abstract
INTRODUCTION Ventriculosubgaleal shunts (VSGSs) require fewer cerebrospinal (CSF) aspirations than ventricular access devices (VADs) for temporization of posthemorrhagic ventricular dilatation (PHVD) in preterm infants. Cost of postoperative CSF aspiration has not been quantified. METHODS We reviewed CSF aspiration and laboratory studies obtained in preterm infants with PHVD and VAD at our institution between 2009 and 2020. Cost per aspiration was calculated for materials, labs, and Medicare fee schedule for ventricular puncture through implanted reservoir. We searched PubMed, Cochrane Library, Embase, CINAHL, and Web of Science for meta-analysis of pooled mean number of CSF aspirations and proportion of patients requiring aspiration. RESULTS Thirty-five preterm infants with PHVD had VAD placed with 22.2 ± 18.4 aspirations per patient. Labs were obtained after every aspiration per local protocol. Cost per aspiration at our institution was USD 935.51. Of 269 published studies, 77 reported on VAD, 29 VSGS, and 13 both. Five studies on VAD (including the current study) had a pooled mean of 25.8 aspirations per patient (95% CI: 16.7-34.8). One study on VSGS reported a mean of 1.6 ± 1.7 aspirations. Three studies on VAD (including the current study) had a pooled proportion of 97.4% of patients requiring aspirations (95% CI: 87.9-99.5). Four studies on VSGS had a pooled proportion of 36.5% requiring aspirations (95% CI: 26.9-47.2). Frequency of lab draws ranged from weekly to daily. Based on costs at our institution, mean number of aspirations, and proportion of patients requiring aspirations, cost difference ranged between USD 4,243 and 23,235 per patient and USD 500,903 and 2.36 million per 100 patients depending on frequency of taps and Medicare locality. DISCUSSION/CONCLUSION Lower number of CSF aspirations using VSGS can be associated with considerably lower cost compared to VAD.

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
Germinal matrix-intraventricular hemorrhage (GM-IVH) is a common intracranial complication in preterm infants, especially those born before 32 weeks of gestation and very-low-birth-weight infants. Hemorrhage originates in the fragile capillary network of the subependymal germinal matrix of the developing brain and may disrupt the ependymal lining and progress into the lateral cerebral ventricle. GM-IVH is associated with increased mortality and abnormal neurodevelopmental outcomes such as posthemorrhagic hydrocephalus, cerebral palsy, epilepsy, severe cognitive impairment, and visual and hearing impairment. Most affected neonates are asymptomatic, and thus, diagnosis is usually made using real-time transfontanellar ultrasound. The present review provides a synopsis of the pathogenesis, grading, incidence, risk factors, and diagnosis of GM-IVH in preterm neonates. We explore brief literature related to outcomes, management interventions, and pharmacological and nonpharmacological prevention strategies for GM-IVH and posthemorrhagic hydrocephalus.

Abstract
ABSTRACT INTRODUCTION: Posthemorrhagic hydrocephalus (PHH) is a common disease process encountered in neonates. Management often includes cerebrospinal fluid (CSF) aspiration through ventricular access devices (VADs). However, a common concern surrounding serial access of implanted subcutaneous reservoirs includes introduction of infection. In addition, there is great variability in aseptic technique. Therefore, the authors sought to evaluate the incidence of VAD access-associated infections in the literature and compare them with the rate of infection found at our institution. We also highlight the use of a preassembled VAD access kit and standardized access protocol, as well as the role of provider education, in maintaining safety and sterility during serial VAD access. METHODS: A single-institution retrospective review was performed for PHH patients younger than 1 year old undergoing serial CSF aspirations via implanted VADs (2009-2019). Patients were excluded if they had a ventriculoperitoneal shunt placed as primary intervention. MEDLINE search for reports of serial VAD access in PHH was also performed. Reports were excluded if they did not include full-text articles in the English literature. RESULTS: At our institution, subcutaneous reservoirs were placed in 37 neonates with PHH for serial CSF aspiration. No infections occurred after a total of 630 taps (average, 17 taps per reservoir; range, 0-83) and 10 420 collective reservoir days (average, 282 per patient; range, 6-3700). Only 2 reservoirs required revision for malfunction. Serial VAD taps for PHH were described in 14 articles in the medical literature, with 7.9% (n = 47/592) of patients reported with tap-related infectious complications. CONCLUSION: A standardized VAD access kit, along with stringent adherence to access protocol, can significantly minimize risk of infection associated with serial VAD access. These principles can be generalized to percutaneous aspiration of CSF from subcutaneous reservoirs placed for other indications to promote safety and sterility of this common procedure.

Abstract
BACKGROUND Preterm infants with post-hemorrhagic hydrocephalus (PHH) are often treated with temporizing measures such as ventricular access devices (VADs) in order to drain cerebrospinal fluid (CSF) prior to permanent diversion with ventriculoperitoneal shunt (VPS) placement. LOCAL PROBLEM There is little consensus on the timing and management of VADs and VPSs. This leads to marked practice variations among treating services that can adversely affect patient outcomes. METHODS This is a quality improvement study evaluating practices from February 2011 to September 2017 including infants with PHH in a single level IV NICU. INTERVENTIONS A multidisciplinary team created a local clinical pathway modified from the Hydrocephalus Clinical Research Network's Shunting Outcomes in Post-Hemorrhagic Hydrocephalus protocol to manage infants with PHH. Methods of CSF diversion and shunt timing were based on weight. Neonatal care providers performed VAD aspiration; timing was guided by imaging and clinical exam criteria. Surgical procedures were performed in the NICU. RESULTS There were 78 patients eligible for the study. Prior to pathway implementation, infections occurred in 4% of VAD and 3% of VPS patients. There have been no infections since inception of the pathway. With pathway implementation, treatment compliance improved from 55 to 86% while conversion compliance rate improved from 89 to 100%. CONCLUSIONS Standardization of care for PHH infants leads to improvement in patient outcomes such as a decrease in time to VAD placement. Reservoir aspirations by the neonatology team did not result in an increase in infection rate.

Abstract
Purpose: Increasing evidence suggests that circulating biomarkers may serve diagnostic and longitudinal monitoring purposes in pediatric neuro-oncology. Mutant tumor DNA is detectable in the cerebrospinal fluid (CSF) of pediatric diffuse midline glioma (DMG) patients and quantity can reflect disease burden. CSF sampling ("liquid biopsy") via a CSF access device could therefore play a role in DMG management. Therefore, we set to evaluate the incidence of hydrocephalus (HCP) in DMG patients, and to characterize ventricular reservoir placement and access practices. Methods: A single institution retrospective review of DMG patients ≤21-years-old was performed (1984-2019). MEDLINE searches for reports of ventricular reservoir or shunt placement in DMG, and reservoir access for intraventricular chemotherapy (IVC) were performed. Results: At our institution, 62.6% of DMG patients (67/108) required intervention for HCP: 19.4% provided transient CSF access (ETV alone n = 3, EVD n = 8, unspecified n = 2), and 80.6% permanent CSF access (ETV + reservoir n = 13, shunt n = 41). Further, 22/34 patients with initially transient CSF devices required conversion to a permanent device. Five devices were revised for malfunction, one for infection. Seventeen articles cited HCP in 22 to 100% of DMG patients. IVC administration was described in 632 patients (seven articles), with 42 infectious and 63 non-infectious complications. Conclusions: Management of HCP is often necessary in children with DMG. Given the low rate of clinical risk associated with VAD placement and access, and the potential utility of longitudinal disease monitoring via CSF analysis, VAD placement could be considered in future clinical trials to guide DMG treatment.

Abstract
INTRODUCTION Among children with hydrocephalus, neonates with intraventricular hemorrhage (IVH) and posthemorrhagic hydrocephalus (PH) are considered a group with one of the highest complication rates of treatment. Despite continued progress in neonatal care, a standardized and reliable guideline for surgical management is missing for this challenging condition. Thus, further research is warranted to compare common methods of surgical treatment. The introduction of neuroendoscopic lavage has precipitated the establishment of an international registry aimed at elaborating key elements of a standardized surgical treatment. METHODS The registry is designed as a multicenter, international, prospective data collection for neonates aged 41 weeks gestation, with an indication for surgical treatment for IVH with ventricular dilatation and progressive hydrocephalus. The following initial temporizing surgical interventions, each used as standard treatment at participating centers, will be compared: external ventricular drainage (EVD), ventricular access device (VAD), ventricular subgaleal shunt (VSGS), and neuroendoscopic lavage (NEL). Type of surgery, perioperative data including complications and mortality, subsequent shunt surgeries, ventricular size, and neurological outcome will be recorded at 6, 12, 36, and 60 months. RESULTS An online, password-protected website will be used to collect the prospective data in a synchronized manner. As a prospective registry, data collection will be ongoing, with no prespecified endpoint. A prespecified analysis will take place after a total of 100 patients in the NEL group have been entered. Analyses will be performed for safety (6 months), shunt dependency (12, 24 months), and neurological outcome (60 months). CONCLUSION The design and online platform of the TROPHY registry will enable the collection of prospective data on different surgical procedures for investigation of safety, efficacy, and neurodevelopmental outcome of neonates with IVH and hydrocephalus. The long-term goal is to provide valid data on NEL that is prospective, international, and multicenter. With the comparison of different surgical treatment modalities, we hope to develop better therapy guidelines for this complex neurosurgical condition.

Abstract
OBJECTIVE To compare neurodevelopmental outcomes of preterm infants with and without intervention for posthemorrhagic ventricular dilatation (PHVD) managed with an "early approach" (EA), based on ventricular measurements exceeding normal (ventricular index [VI] <+2 SD/anterior horn width <6 mm) with initial temporizing procedures, followed, if needed, by permanent shunt placement, and a "late approach" (LA), based on signs of increased intracranial pressure with mostly immediate permanent intervention. METHODS Observational cohort study of 127 preterm infants (gestation <30 weeks) with PHVD managed with EA (n = 78) or LA (n = 49). Ventricular size was measured on cranial ultrasound. Outcome was assessed at 18-24 months. RESULTS Forty-nine of 78 (63%) EA and 24 of 49 (49%) LA infants received intervention. LA infants were slightly younger at birth, but did not differ from EA infants for other clinical measures. Initial intervention in the EA group occurred at younger age (29.4/33.1 week postmenstrual age; p < 0.001) with smaller ventricles (VI 2.4/14 mm >+2 SD; p < 0.01), and consisted predominantly of lumbar punctures or reservoir taps. Maximum VI in infants with/without intervention was similar in EA (3/1.5 mm >+2 SD; p = 0.3) but differed in the LA group (14/2.1 mm >+2 SD; p < 0.001). Shunt rate (20/92%; p < 0.001) and complications were lower in EA than LA group. Most EA infants had normal outcomes (>-1 SD), despite intervention. LA infants with intervention had poorer outcomes than those without (p < 0.003), with scores <-2 SD in 81%. CONCLUSION In preterm infants with PHVD, those with early intervention, even when eventually requiring a shunt, had outcomes indistinguishable from those without intervention, all being within the normal range. In contrast, in infants managed with LA, need for intervention predicted worse outcomes. Benefits of EA appear to outweigh potential risks. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that for preterm infants with PHVD, an EA to management results in better neurodevelopmental outcomes than a LA.

Abstract
OBJECT Posthemorrhagic hydrocephalus (PHH) in the preterm infant remains a major neurological complication of prematurity. The authors first described insertion of a specially designed low-profile subcutaneous ventricular catheter reservoir for temporary management of hydrocephalus in 1983. This report presents the follow-up experience with the surgical management of PHH in this population and describes outcomes both in infants who were stable for permanent shunt insertion and those initially temporized with a ventricular reservoir (VR) prior to permanent ventriculoperitoneal (VP)/ventriculoatrial (VA) shunt placement. METHODS A retrospective review was undertaken of the medical records of all premature infants surgically treated for posthemorrhagic hydrocephalus (PHH) between 1997 and 2012 at Children's Hospital Los Angeles. RESULTS Over 14 years, 91 preterm infants with PHH were identified. Fifty neonates received temporizing measures via a VR that was serially tapped for varying time periods. For the remaining 41 premature infants, VP/VA shunt placement was the first procedure. Patients with a temporizing measure as their initial procedure had undergone CSF diversion significantly earlier in life than those who had permanent shunting as the initial procedure (29 vs 56 days after birth, p < 0.01). Of the infants with a VR as their initial procedure, 5/50 (10%) did not undergo subsequent VP/VA shunt placement. The number of shunt revisions and the rates of loculated hydrocephalus and shunt infection did not statistically differ between the 2 groups. CONCLUSIONS Patients with initial VR insertion as a temporizing measure received a CSF diversion procedure significantly earlier than those who received a permanent shunt as their initial procedure. Otherwise, the outcomes with regard to shunt revisions, loculated hydrocephalus, and shunt infection were not different for the 2 groups.

Abstract
Germinal matrix hemorrhage (GMH) is defined as the rupture of immature blood vessels in the subependymal zone of premature infants with significant mortality and morbidity. Considering the notable social and ecological stress brought by GMH-induced brain injury and sequelae, safe and efficient pharmacological preventions are badly needed. Currently, several appropriate animal models are available to mimic the clinical outcomes of GMH in human patients. In the long run, hemorrhagic strokes are the research target. Previously, we found that minocycline was efficient to alleviate GMH-induced brain edema and posthemorrhagic hydrocephalus (PHH) in rats, which may be closely related to the activation of cannabinoid receptor 2 (CB2R). However, how the two molecules correlate and the underlined molecular pathway remain unknown. To extensively understand current experimental GMH treatment, this literature review critically evaluates existing therapeutic strategies, potential treatments, and potentially involved molecular mechanisms. Each strategy has its own advantages and disadvantages. Some of the mechanisms are still controversial, requiring an increasing number of animal experiments before the therapeutic strategy would be widely accepted.

Abstract
OBJECT The optimal clinical management of intraventricular hemorrhage (IVH) and posthemorrhagic ventricular dilation (PHVD)/posthemorrhagic hydrocephalus (PHH) in premature infants remains unclear. A common approach involves temporary treatment of hydrocephalus in these patients with a ventriculosubgaleal shunt (VSGS), ventricular access device (VAD), or external ventricular drain (EVD) until it becomes evident that the patient needs and can tolerate permanent CSF diversion (i.e., ventriculoperitoneal shunt). The present systematic review and meta-analysis aimed to provide a robust and comprehensive summary of the published literature regarding the clinical outcomes and complications of these 3 techniques as temporizing measures in the management of prematurity-related PHVD/PHH. METHODS The authors searched MEDLINE, EMBASE, CINAHL, Google Scholar, and the Cochrane Library for studies published through December 2013 on the use of VSGSs, VADs, and/or EVDs as temporizing devices for the treatment of hydrocephalus following IVH in the premature neonate. Data pertaining to patient demographic data, study methods, interventions, and outcomes were extracted from eligible articles. For each of the 3 types of temporizing device, the authors performed meta-analyses examining 6 outcomes of interest, which were rates of 1) obstruction; 2) infection; 3) arrest of hydrocephalus (i.e., permanent shunt independence); 4) mortality; 5) good neurodevelopmental outcome; and 6) revision. RESULTS Thirty-nine studies, representing 1502 patients, met eligibility criteria. All of the included articles were observational studies; 36 were retrospective and 3 were prospective designs. Nine studies (n = 295) examined VSGSs, 24 (n = 962) VADs, and 9 (n = 245) EVDs. Pooled rates of outcome for VSGS, VAD, and EVD, respectively, were 9.6%, 7.3%, and 6.8% for obstruction; 9.2%, 9.5%, and 6.7% for infection; 12.2%, 10.8%, and 47.3% for revision; 13.9%, 17.5%, and 31.8% for arrest of hydrocephalus; 12.1%, 15.3%, and 19.1% for death; and 58.7%, 50.1%, and 56.1% for good neurodevelopmental outcome. CONCLUSIONS This study provides robust estimates of outcomes for the most common temporizing treatments for IVH in premature infants. With few exceptions, the range of outcomes was similar for VSGS, VAD, and EVD.

Abstract
OBJECT Intraventricular hemorrhage in premature infants often leads to progressive ventricular dilation and the need for ventricular reservoir placement. Unfortunately, these reservoirs have a higher rate of infection than ventriculoperitoneal shunts in premature babies. The authors analyzed the risk factors for infection in this population and studied whether the implementation of an institutional protocol for shunt placement had a corollary effect on ventricular access device (VAD) infection rates in premature neonates with intraventricular hemorrhage. METHODS The authors conducted a retrospective cohort review of consecutive premature neonates in whom VADs were inserted in the operating room at Primary Children's Hospital between June 2003 and June 2011 to identify risk factors for infection. Medical records were reviewed for information on infection (culture proven or eroded hardware at 90 days), gestational age at birth, weight, gestational age at surgery, intrathecal antibiotics, hemorrhage, death, and surgeon. The institution used a pilot protocol for shunt infection reduction in 2006-2007, and then the full Hydrocephalus Clinical Research Network protocol from June 2007 to 2011, and the rates of infection during these periods were analyzed. Confounding factors such as sepsis, necrotizing enterocolitis, and a history of meningitis were also analyzed. RESULTS The overall infection rate was 10.5% (11 patients) in the 105 patients identified. Gestational age at procedure was a significant risk factor for infection (p=0.05). Meningitis was significantly associated with infection, with 63% of the infected group having had prior meningitis compared with 7% for the noninfected group (p<0.001). Concurrent with the implementation of the protocol to reduce shunt infection, the VAD infection rate decreased from 14.7% to 5.4% (p=0.2). CONCLUSIONS Gestational age at procedure and previous meningitis were significant risk factors for VAD infections. In addition, the implementation of an institutional standardized shunt protocol for ventriculoperitoneal shunts may have altered the operating room team's behavior, indicated by a nonmandated use of intrathecal antibiotics in VAD surgeries, contributing to a reduced VAD infection rate. Although the observed difference was not statistically significant with the small sample size, the authors believe that these findings deserve further study.

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
OBJECT The most common neurosurgical condition observed in preterm infants is intraventricular hemorrhage (IVH), which often results in posthemorrhagic hydrocephalus (PHH). These conditions portend an unfavorable prognosis; therefore, the potential for poor neurodevelopmental outcomes necessitates a better understanding of the comparative effectiveness of 2 temporary devices commonly used before the permanent insertion of a ventriculoperitoneal (VP) shunt: the ventricular reservoir and the ventriculosubgaleal shunt (VSGS). METHODS The authors analyzed retrospectively collected information for 90 patients with IVH and PHH who were treated with insertion of a ventricular reservoir (n = 44) or VSGS (n = 46) at their institution over a 14-year period. RESULTS The mean gestational age and weight at device insertion were lower for VSGS patients (30.1 ± 1.9 weeks, 1.12 ± 0.31 kg) than for reservoir patients (31.8 ± 2.9 weeks, 1.33 ± 0.37 kg; p = 0.002 and p = 0.004, respectively). Ventricular reservoir insertion was predictive of more CSF taps prior to VP shunt placement compared with VSGS placement (10 ± 8.7 taps vs 1.6 ± 1.7 taps, p < 0.001). VSGS patients experienced a longer time interval prior to VP shunt placement than reservoir patients (80.8 ± 67.5 days vs 48.8 ± 26.4 days, p = 0.012), which corresponded to VSGS patients gaining more weight by the time of shunt placement than reservoir patients (3.31 ± 2.0 kg vs 2.42 ± 0.63 kg, p = 0.016). Reservoir patients demonstrated a trend toward more positive CSF cultures compared with VSGS patients (n = 9 [20.5%] vs n = 5 [10.9%], p = 0.21). There were no significant differences in the rates of overt device infection requiring removal (reservoir, 6.8%; VSGS, 6.5%), VP shunt insertion (reservoir, 77.3%; VSGS, 76.1%), or early VP shunt infection (reservoir, 11.4%; VSGS, 13.0%) between the 2 cohorts. CONCLUSIONS Although the rates of VP shunt requirement and device infection were similar between patients treated with the reservoir versus the VSGS, VSGS patients were significantly older and had achieved greater weights at the time of VP shunt insertion. The authors' results suggest that the VSGS requires less labor-intensive management by ventricular tapping; the VSGS patients also attained higher weights and more optimal surgical candidacy at the time of VP shunt insertion. The potential differences in long-term developmental and neurological outcomes between VSGS and reservoir placement warrant further study.

Abstract
OBJECT Most CSF-diverting shunt systems have an access port that can be percutaneously tapped. Tapping the shunt can yield valuable information as to its function and whether an infection is present. The fear of causing a shunt infection by tapping may limit the physician's willingness to do so. The authors of this study investigate the risk of infecting a shunt secondary to percutaneous tapping. METHODS Following institutional review board approval, CSF specimens obtained from tapping an indwelling CSF-diverting shunt during the 2011 and 2012 calendar years were identified and matched with clinical information. A culture-positive CSF sample was defined as an infection. If results were equivocal, such as a broth-only-positive culture, a repeat CSF specimen was examined. The CSF was obtained by tapping the shunt access port with a 25-gauge butterfly needle after prepping the unshaven skin with chlorhexidine. RESULTS During the study period, 266 children underwent 542 shunt taps. With 541 taps, no clinical evidence of a subsequent shunt infection was found. One child's CSF went from sterile to infected 11 days later; however, this patient had redness along the shunt tract at the time of the initial sterile tap. CONCLUSIONS The risk of infection from tapping a shunt is remote if the procedure is done correctly.

Abstract
PURPOSE Ventricular access devices (VAD) are often used for treatment of posthemorrhagic hydrocephalus (PHH) in preterm infants. The reported rates of infection have varied and range from 0 to 22 %. The objective of our study is to present our VAD associated infection at our institution. METHODS The charts for patients that had VADs inserted between May 1, 2009 and October 31, 2013 at a single institution (Children's Healthcare of Atlanta) were retrospectively reviewed. The number of VAD infections, defined as either cerebrospinal fluid (CSF)-positive cultures or wound complication, was recorded. Of patients that survived, the number of VAD to shunt conversions was also examined. The data from 15 previously published studies were pooled to determine overall VAD infection and VAD to shunt conversion rates. RESULTS A total of 142 VADs were placed. There were 13 infections (9.2 %), 11 of which had CSF-positive cultures (7.7 %). There were two wound complications with negative CSF cultures. Six patients died after VAD placement for reasons unrelated to their VAD surgeries (4.2 %). In the remaining patients, there were 113 VAD to shunt conversions (83.1 %). Fifteen studies that reported VAD infections were analyzed; an overall infection rate of 7.0 % and VAD to shunt conversion rate of 79 % were calculated. CONCLUSIONS While VAD is a valuable tool to treat PHH, it remains a procedure with an infection rate between 7.0 and 8.0 %. Close follow-up is needed to capture these adverse events as early as possible. Approximately 80 % of patients with PHH will require permanent CSF diversion.

Abstract
Background: Between 2005 and 2010, we treated patients with hydrocephalus related to cerebral metastases, who were not good candidates for surgical resection by either endoscopic third ventriculostomy (ETV) or ventriculoperitoneal shunting (VPS). Patients were excluded from ETV if they had a clinical history suggestive of non-obstructive hydrocephalus, including: (1) history of infection or ventricular hemorrhage and (2) leptomeningeal carcinomatosis. The rest of the patients were treated with VPS. Methods: We analyzed the clinical outcome of these patient cohorts, to determine whether the efficacy of VPS was compromised due to a history of infection, ventricular hemorrhage, or leptomeningeal carcinomatosis, and compared these results to those patients who underwent ETV. Results: Sixteen patients were treated with ETV and 36 patients were treated with VPS. The overall efficacy of symptomatic palliation was comparable in the ETV and VPS patients (ETV = 69%, VPS = 75%). In both groups, patients with more severe hydrocephalic symptoms such as nausea, vomiting, and lethargy were more likely to benefit from the procedure. The overall complication rate for the two groups was comparable (ETV = 12.6%, VPS = 19.4%), although the spectrum of complications differed. The overall survival, initial Karnofsky performance status (KPS), and three-month KPS, were similarly comparable (median survival: ETV 3 months, VPS 5.5 months; initial KPS: ETV = 66 ± 7, VPS = 69 ± 12; 3 months KPS: ETV = 86 ± 7, KPS = 84 ± 12). Conclusion: VPS remains a reasonable option for poor RPA grade metastasis patients with hydrocephalus, even in the setting of a previous infection, hemorrhage, or in those with leptomeningeal disease. Optimal treatment of this population will involve the judicious consideration of the relative merits of VPS and ETV.

Abstract
OBJECT Preterm infants are at risk for perinatal complications, including germinal matrix-intraventricular hemorrhage (IVH) and subsequent posthemorrhagic hydrocephalus (PHH). This review summarizes the current understanding of the epidemiology, pathophysiology, management, and outcomes of IVH and PHH in preterm infants. METHODS The MEDLINE database was systematically searched using terms related to IVH, PHH, and relevant neurosurgical procedures to identify publications in the English medical literature. To complement information from the systematic search, pertinent articles were selected from the references of articles identified in the initial search. RESULTS This review summarizes the current knowledge regarding the epidemiology and pathophysiology of IVH and PHH, primarily using evidence-based studies. Advances in obstetrics and neonatology over the past few decades have contributed to a marked improvement in the survival of preterm infants, and neurological morbidity is also starting to decrease. The incidence of IVH is declining, and the incidence of PHH will likely follow. Currently, approximately 15% of preterm infants who suffer severe IVH will require permanent CSF diversion. The clinical presentation and surgical management of symptomatic PHH with temporary ventricular reservoirs (ventricular access devices) and ventriculosubgaleal shunts and permanent ventriculoperitoneal shunts are discussed. Preterm infants who develop PHH that requires surgical treatment remain at high risk for other related neurological problems, including cerebral palsy, epilepsy, and cognitive and behavioral delay. This review highlights numerous opportunities for further study to improve the care of these children. CONCLUSIONS A better grasp of the pathophysiology of IVH is beginning to impact the incidence of IVH and PHH. Neonatologists conduct rigorous Class I and II studies to advance the outcomes of preterm infants. The need for well-designed multicenter trials is essential because of the declining incidence of IVH and PHH, variations in referral patterns, and neonatal ICU and neurosurgical management. Well-designed multicenter trials will eventually produce evidence to enable neurosurgeons to provide their smallest, most vulnerable patients with the best practices to minimize perioperative complications and permanent shunt dependence, and most importantly, optimize long-term neurodevelopmental outcomes.

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
OBJECT Intraventricular hemorrhage (IVH) and progressive posthemorrhagic ventricular dilation (PPHVD) may result in significant neurological morbidity in preterm infants. At present, there is no consensus regarding the optimal timing or type of neurosurgical procedure to best treat PPHVD. Conflicting data exist regarding the relative risks and benefits of two commonly used temporizing neurosurgical procedures (TNPs), ventricular access devices ([VADs] or ventricular reservoirs) versus ventriculosubgaleal (VSG) shunts. This study was designed to address this issue. METHODS This is a single-center, 10-year retrospective review of all preterm infants admitted to the St. Louis Children's Hospital neonatal intensive care unit (NICU) with Papile Grade III-IV IVH. The development of PPHVD and the requirement for and type of TNP were recorded. Rates of TNP complication, ventriculoperitoneal (VP) shunt implantation, shunt infection, and mortality rates were used to compare the efficacy and limitations of each TNP type. RESULTS Over this 10-year interval, 325 preterm infants with Grade III-IV IVH were identified, with trends showing an increasing number of affected infants annually, and an increasing number of TNPs were required annually. Ninety-five (29.2%) of the 325 infants underwent a TNP for PPHVD (65 VADs, 30 VSG shunts). The rate of permanent VP shunt implantation for all TNPs was 72.6% (69 of 95 infants). Forty-nine (75.4%) of the 65 infants treated with VADs and 20 (66.7%) of the 30 treated with VSG shunts required VP shunts (p = 0.38). There was no statistical difference between VAD or VSG shunt with regard to TNP-related infection (p = 0.57), need for TNP revision (p = 0.16), subsequent shunt infection (p = 0.77), shunt revision rate (p = 0.58), or mortality rate (p = 0.24). CONCLUSIONS Rates of IVH and PPHVD observed at the authors' center have increased over time. In contrast to recent literature, the results from the current study did not demonstrate a difference in complication rate or requirement for permanent VP shunt placement between VADs and VSG shunts. Definitive conclusions will require a larger, prospective trial.
