Abstract
The survival rate of preterm infants is increasing as a result of technological advances. The incidence of intraventricular hemorrhages (IVH) in preterm infants ranges from 25% to 30%, of which 30% to 50% are severe IVH (Volpe III-IV, Volpe III is defined as intraventricular bleeding occupying more than 50% of the ventricular width and acute lateral ventricle dilatation, Volpe IV is defined as intraventricular hemorrhage combined with venous infarction) and probably lead to posthemorrhagic ventricular dilatation (PHVD). Severe IVH and subsequent PHVD have become the leading causes of brain injury and neurodevelopmental dysplasia in preterm infants. This review aims to review the literature on the diagnosis and therapeutic strategies for PHVD and provide some recommendations for management to improve the neurological outcomes.

Abstract
Treatment for pediatric hydrocephalus aims not only to shrink the enlarged ventricle morphologically but also to create an intracranial environment that provides the best neurocognitive development and to deal with various treatment-related problems over a long period of time. Although the primary diseases that cause hydrocephalus are diverse, the ventricular peritoneal shunt has been introduced as the standard treatment for several decades. Nevertheless, complications such as shunt infection and shunt malfunction are unavoidable; the prognosis of neurological function is severely affected by such factors, especially in newborns and infants. In recent years, treatment concepts have been attempted to avoid shunting, mainly in the context of pediatric cases. In this review, the current role of neuroendoscopic third ventriculostomy for noncommunicating hydrocephalus is discussed and a new therapeutic concept for post intraventricular hemorrhagic hydrocephalus in preterm infants is documented. To avoid shunt placement and achieve good neurodevelopmental outcomes for pediatric hydrocephalus, treatment modalities must be developed.

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.

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
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 Posthaemorrhagic ventricular dilatation in preterm infants is primarily treated using temporising measures, of which the placement of a ventricular access device (VAD) is one option. Permanent shunt dependency rates are high, though vary widely. In order to improve the treatment burden and lower shunt dependency rates, we implemented several changes over the years. One of these changes involves the setting of the surgery from general anaesthesia in the OR to local anaesthesia in bed at the neonatal intensive care unit (NICU), which may seem counterintuitive to many. In this article, we describe our surgical technique and present the results of this regimen and compare it to our previous techniques. METHODS Retrospective study of a consecutive series of 37 neonates with posthaemorrhagic ventricular dilatation (PHVD) treated using a VAD, with a cohort I (n = 13) treated from 2004 to 2008 under general anaesthesia in the OR, cohort II (n = 11) treated from 2009 to 2013 under general anaesthesia in the NICU and cohort III (n = 13) treated from December 2013 to December 2017 under local anaesthesia on the NICU. RESULTS The overall infection rate was 14%; the VAD revision rate was 22% and did not differ significantly between the cohorts. Procedures under local anaesthesia never required conversion to general anaesthesia and were well tolerated. After an average of 33 tapping days, 38% of the neonates received a permanent ventriculoperitoneal (VP) shunt. The permanent VP shunt rate was 9% with VAD placement under local anaesthesia and 52% when performed under general anaesthesia (p = 0.02). CONCLUSION Bedside placement of VADs for PHVD under local anaesthesia in neonates is a low-risk, well-tolerated procedure that results in at least equal results to surgery performed under general anaesthesia and/or performed in an OR.

Abstract
For decades, intracerebroventricular (ICV), or intraventricular, devices have been used in the treatment of a broad range of pediatric and adult central nervous system (CNS) disorders. Due to the limited permeability of the blood brain barrier, diseases with CNS involvement may require direct administration of drugs into the brain to achieve full therapeutic effect. A recent comprehensive literature review on the clinical use and complications of ICV drug delivery revealed that device-associated complication rates are variable, and may be as high as 33% for non-infectious complications and 27% for infectious complications. The variability in reported safety outcomes may be driven by a lack of consensus on best practices of device use. Numerous studies have demonstrated that employing strict aseptic techniques and following stringent protocols can dramatically reduce complications. Key practices to be considered in facilitating the safe, long-term use of these devices are presented.

Abstract
OBJECTIVE Previous Hydrocephalus Clinical Research Network (HCRN) retrospective studies have shown a 15% difference in rates of conversion to permanent shunts with the use of ventriculosubgaleal shunts (VSGSs) versus ventricular reservoirs (VRs) as temporization procedures in the treatment of hydrocephalus due to high-grade intraventricular hemorrhage (IVH) of prematurity. Further research in the same study line revealed a strong influence of center-specific decision-making on shunt outcomes. The primary goal of this prospective study was to standardize decision-making across centers to determine true procedural superiority, if any, of VSGS versus VR as a temporization procedure in high-grade IVH of prematurity. METHODS The HCRN conducted a prospective cohort study across 6 centers with an approximate 1.5- to 3-year accrual period (depending on center) followed by 6 months of follow-up. Infants with premature birth, who weighed less than 1500 g, had Grade 3 or 4 IVH of prematurity, and had more than 72 hours of life expectancy were included in the study. Based on a priori consensus, decisions were standardized regarding the timing of initial surgical treatment, upfront shunt versus temporization procedure (VR or VSGS), and when to convert a VR or VSGS to a permanent shunt. Physical examination assessment and surgical technique were also standardized. The primary outcome was the proportion of infants who underwent conversion to a permanent shunt. The major secondary outcomes of interest included infection and other complication rates. RESULTS One hundred forty-five premature infants were enrolled and met criteria for analysis. Using the standardized decision rubrics, 28 infants never reached the threshold for treatment, 11 initially received permanent shunts, 4 were initially treated with endoscopic third ventriculostomy (ETV), and 102 underwent a temporization procedure (36 with VSGSs and 66 with VRs). The 2 temporization cohorts were similar in terms of sex, race, IVH grade, head (orbitofrontal) circumference, and ventricular size at temporization. There were statistically significant differences noted between groups in gestational age, birth weight, and bilaterality of clot burden that were controlled for in post hoc analysis. By Kaplan-Meier analysis, the 180-day rates of conversion to permanent shunts were 63.5% for VSGS and 74.0% for VR (p = 0.36, log-rank test). The infection rate for VSGS was 14% (5/36) and for VR was 17% (11/66; p = 0.71). The overall compliance rate with the standardized decision rubrics was noted to be 90% for all surgeons. CONCLUSIONS A standardized protocol was instituted across all centers of the HCRN. Compliance was high. Choice of temporization techniques in premature infants with IVH does not appear to influence rates of conversion to permanent ventricular CSF diversion. Once management decisions and surgical techniques are standardized across HCRN sites, thus minimizing center effect, the observed difference in conversion rates between VSGSs and VRs is mitigated.

Abstract
Intrathecal delivery methods have been used for many decades to treat a broad range of central nervous system disorders. A literature review demonstrated that intracerebroventricular route is an established and well-tolerated method for prolonged central nervous system drug delivery in pediatric and adult populations. Intracerebroventricular devices were present in patients from one to 7156 days. The number of punctures per device ranged from 2 to 280. Noninfectious complication rates per patient (range, 1.0% to 33.0%) were similar to infectious complication rates (0.0% to 27.0%). Clinician experience and training and the use of strict aseptic techniques have been shown to reduce the frequency of complications.

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
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
PURPOSE Intraventricular hemorrhage is the most common cause of infantile acquired hydrocephalus. Our objective is to determine if the implantation of ventriculoperitoneal shunt in posthemorrhagic hydrocephalus as a primary and definitive neurosurgical treatment, with no previous temporary procedures, would decrease complication rates with good functional outcomes. METHODS Two hundred seventy-one patients with germinal matrix hemorrhage were diagnosed at the Carlos Haya Hospital between 2003 and 2010. Forty-seven patients underwent ventriculoperitoneal shunt after developing symptomatic hydrocephalus. The minimum weight required for shunt implantation was 1,500 g. We recorded complications related to the surgical procedure and analyzed functional state with a self-developed four-grade scale. RESULTS One hundred thirty-nine (51.3 %) patients with intraventricular hemorrhage developed ventricular dilatation, but only 47 patients (17.34 %) needed shunting. In seven cases, temporary neurosurgical procedures were performed, but in all of them, this was followed by ventriculoperitoneal shunt implantation. The infection rate was 4.25 %, and shunt obstruction rate was 4.25 %. More than 80 % of patients were classified as good or excellent functional state. Mean follow-up period was 38.75 months (SD, 27.09; range, 1-102 months). CONCLUSIONS Ventriculoperitoneal shunting as a primary neurosurgical treatment in posthemorrhagic hydrocephalus would decrease surgical morbidity with good functional outcome.

Abstract
OBJECTIVE To delineate the impact of early (≤ 25 days of life) versus late (> 25 days) external ventricular drainage (EVD) on the neurodevelopmental outcome of preterm infants with posthemorrhagic hydrocephalus (PHH) following intraventricular hemorrhage (IVH). METHODS We retrospectively categorized 32 premature infants with PHH into two groups according to whether they underwent early (n = 10) or late (n = 22) EVD. We administered the Battelle Developmental Inventory II and a neuromotor examination (median age, 73 months, range: 29-100). RESULTS In adjusted comparisons, early EVD was associated with better scores than late EVD in adaptive (79 ± 22.6 vs. 58.8 ± 8.1, P = .01), personal social (90.7 ± 26 vs. 67.3 ± 15.9, P = .02), communication (95.4 ± 27.5 vs. 69.6 ± 20.5, P = .04) and cognitive (78.9 ± 24.4 vs. 60.7 ± 11.5, P = .055) functions. Three (30%) early EVD infants had severe (<2.5 standard deviation) cognitive disability compared to 18 (82%) late EVD infants (P = .03). The incidences of cerebral palsy and neurosurgical complications were equal for the two groups. Subgroup analyses suggested that early EVD was beneficial in infants with original grade III IVH (n = 15, P < 0.05), but that it had no beneficial effects in infants with prior parenchymal injury (n = 17, P = NS). CONCLUSION In this small retrospective series, early EVD is associated with lower rates of cognitive, communication and social disabilities than later EVD in infants with PHH without prior parenchymal injury. A randomized prospective trial is warranted.

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
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
OBJECTIVE Controlled removal of cerebrospinal fluid (CSF) by serial tapping of ventricular reservoir, such as the McComb reservoir, is an effective way to decompress the ventricular system in preterm infants with rapidly progressing post-hemorrhagic ventricular dilatation (PHVD) while awaiting optimal conditions for permanent CSF drainage through a ventriculo-peritoneal shunt. However, the data regarding the risk of infection from repeated invasive tapping of a ventricular reservoir over a prolonged period are scarce. The aim of this study is to determine the incidence of ventricular reservoir infection from repeated tapping and to evaluate how often reservoir infection accompanies blood culture-proven sepsis in preterm infants with PHVD. STUDY DESIGN We reviewed the medical records of all infants with PHVD receiving serial reservoir tap at the University of Michigan from January 2000 through June 2007. Serial reservoir taps were carried out by the neonatology team using aseptic technique. Surveillance CSF cultures were sent on a weekly basis as per unit practice or when clinical sepsis was suspected. Reservoir-tapping-related infection was present if a reservoir became infected during serial tapping 7 days or more after surgical placement of the reservoir. RESULT During the study period, ventricular reservoirs were placed in 35 infants for management of hydrocephalus. Six infants (17%) received ventricular reservoirs secondary to post-meningitic hydrocephalus or congenital brain malformations and were excluded. In the remaining 29 infants (birth weight: 1070+/-639 g (range 525 to 3204); gestational age: 26.9+/-4.1 weeks (range 23 to 40)) with PHVD, serial tapping of the ventricular reservoir was performed on 681 occasions (average number of taps per infant: 24 (range 2 to 82)). There were no cases of CSF culture-proven reservoir infection related to repeated taps. Thirteen of the 29 (45%) infants with PHVD developed blood culture-proven late onset sepsis with the following organisms: coagulase-negative Staphylococcus (9), Candida albicans (2), Escherichia coli (1), and Staphylococcus aureus (1), but all of the accompanying CSF cultures from the reservoir were negative. CONCLUSION Ventricular reservoir infection from serial taps neither occurred in this consecutive series of preterm infants with PHVD, nor did ventricular reservoir infection accompany blood culture-proven sepsis. Concern of reservoir infection from repeated tapping should not be a limiting factor against placement of reservoirs.

Abstract
BACKGROUND The management of hydrocephalus secondary to intraventricular haemorrhage in neonates can be controversial. Temporary diversion of cerebrospinal fluid (CSF) is often required due to the low birth weight and high risks of shunting in these patients. Ventriculosubgaleal (VSG) CSF diversion is an effective way of achieving this goal whilst minimising the risks of complications. It is a well-described technique but is rarely used in contemporary neurosurgical practice. METHODS Nine neonates treated with VSG shunting for post-haemorrhagic hydrocephalus were assessed. Gestational age, birth weight, duration of treatment efficacy, requirement for permanent shunting and complications were recorded. RESULTS In all 9 patients, the VSG shunt controlled the progression of hydrocephalus. A permanent shunt was avoided in 2 patients. One patient required revision of the subgaleal shunt to extend the interval to the insertion of a permanent shunt. None of the patients developed any CSF infection or leak. CONCLUSION VSG CSF diversion offers a simple, effective and relatively safe means of treating hydrocephalus in the neonate, with a low risk of complications and the possibility of avoiding permanent shunting.

Abstract
OBJECTIVE It is well known that 10-15% of hydrocephalus cases at childhood and 40-50% in premature infants, occur following Germinal matrix hemorrhage (GMH). Such hemorrhages are reported to arise due to the rupture of germinal matrix (GM) vessels as a result of cerebral blood flow changes among infants with <1500 g birth weight and <32 weeks old. Intraventricular hemorrhage (IVH) associated with GMH leads to a disruption in the cerebrospinal fluid (CSF) and ventricular dilatation. Ventriculosubgaleal shunt (VSGS) is preferred in those hydrocephalus cases because it is a simple and rapid method, precludes the need for repetitive aspiration for evacuation of CSF, establishes a permanent decompression without causing electrolyte and nutritional losses, and aims to protect the cerebral development of newborns with GMH. MATERIAL AND METHOD The present study comprises 25 premature cases, subjected to VSGS and diagnosed with post-hemorrhagic hydrocephalus (PHH) arising from IVH associated with GM, and low birth weight (LBW) in the Neurosurgery Department of the Medical Faculty of Erciyes University between July 2002 and September 2006. VSGS surgery was performed on those cases, and their clinical and radiological prognoses were monitored with regard to several parameters. RESULTS Mortality and morbidity results were found to be lower than those in PPH treatment methods. While prognosis of grade 4 GMHs was poor, grades 2 and 3 GMHs displayed a much better prognosis after VSGS along with complete recovery in some hydrocephalus cases.

Abstract
OBJECT The purpose of this study was to define the incidence of permanent shunt placement and infection in patients who have undergone the 2 most commonly performed temporizing procedures for posthemorrhagic hydrocephalus (PHH) of prematurity: ventriculosubgaleal (VSG) shunt placement and ventricular reservoir placement for intermittent tapping. METHODS The 4 centers of the Hydrocephalus Clinical Research Network participated in a retrospective chart review of infants with PHH who underwent treatment at each institution between 2001 and 2006. Patients were included if they had received a diagnosis of Grade 3 or 4 intraventricular hemorrhage, weighed < 1500 g at birth, and had received surgical intervention. The authors determined the incidence of conversion from a temporizing device to a permanent shunt, the incidence of CSF infection during temporization, and the 6-month CSF infection rate after permanent shunt placement. RESULTS Thirty-one (86%) of 36 patients who received VSG shunts and 61 (69%) of 88 patients who received ventricular reservoirs received permanent CSF diversion with a shunt (p = 0.05). Five patients (14%) in the VSG shunt group had CSF infections during temporization, compared with 11 patients (13%) in the ventricular reservoir group (p = 0.83). The 6-month incidence of permanent shunt infection in the VSG shunt group was 16% (5 of 31), compared with 12% (7 of 61) in the reservoir placement group (p = 0.65). For the first 6 months after permanent shunt placement, infants with no preceding temporizing procedure had an infection rate of 5% (1 of 20 infants) and those who had undergone a temporizing procedure had an infection rate of 13% (12 of 92; p = 0.45). CONCLUSIONS The use of intermittent tapping of ventricular reservoirs in this population appears to lead to a lower incidence of permanent shunt placement than the use of VSG shunts. The incidence of infection during temporization and for the initial 6 months after conversion appears comparable for both groups. The apparent difference identified in this pilot study requires confirmation in a more rigorous study.

Abstract
AIM Progressive posthaemorrhagic ventricular dilatation (PHVD) may induce abnormal amplitude-integrated electroencephalographic (aEEG) activity prior to clinical deterioration or significant cerebral ultrasound changes. These abnormalities might be ameliorated with cerebrospinal fluid (CSF) drainage. The aims of this study were to investigate the occurrence of aEEG-abnormalities with progressive PHVD in relation to clinical and cerebral ultrasound changes and to evaluate whether CSF drainage results in aEEG improvement. METHODS aEEG and cerebral ultrasound scans were performed in 12 infants with PHVD, before and after CSF drainage, until normalization of aEEG occurred. RESULTS aEEG was abnormal with progressive PHVD in all patients. Concurrently, 60% of the patients were clinically stable without deterioration in ultrasonographic cerebral abnormalities. Post drainage, continuous pattern was restored in all but one patient, whereas the frequency of discontinuous pattern decreased in nine patients and burst-suppression pattern decreased in all but one patient. Low-voltage pattern was only observed in one patient who suffered severe grade IV IVH and died one week after EVD placement. Sleep-wake cycling matured in 75%. CONCLUSION These findings demonstrate the impact of CSF drainage on compromised aEEG-activity associated with PHVD. aEEG changes indicative of impaired cerebral function were apparent before clinical deterioration or major ultrasound changes. These changes were reversible with CSF drainage. aEEG should therefore be used in addition to clinical observation and ultrasound when monitoring PHVD.

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
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
BACKGROUND Since 1992, infants with progressive posthaemorrhagic ventricular dilatation (PHVD) have been treated in the Neonatal Intensive Care Unit, Wilhelmina Children's Hospital, Utrecht, The Netherlands, with a ventricular reservoir. OBJECTIVE To retrospectively study the incidence of infection using this invasive procedure. METHODS Between January 1992 and December 2003, 76 preterm infants were treated with a ventricular reservoir. Infants admitted during two subsequent periods were analysed: group 1 included infants admitted during 1992-7 (n = 26) and group 2 those admitted during 1998-2003 (n = 50). Clinical characteristics and number of reservoir punctures were evaluated. The incidence of complications over time was assessed, with a focus on the occurrence of infection of the reservoir. RESULTS The number of punctures did not change during both periods. Infection was significantly less common during the second period (4% (2/50) v 19.2% (5/26), p = 0.029). CONCLUSION The use of a ventricular reservoir is a safe treatment to ensure adequate removal of cerebrospinal fluid in preterm infants with PHVD. In experienced hands, the incidence of infection of the ventricular reservoir or major complications remains within acceptable limits.

Abstract
To determine the factors affecting the neurodevelopmental outcome in children with posthemorrhagic hydrocephalus, 78 children with intraventricular hemorrhage grade 3 or 4 were analyzed concerning the outcome in relation to the grade of intraventricular hemorrhage and intervention (surgical, medical, or no intervention) by means of a follow-up study. The mean age of the subjects at the last follow-up was 9.8 years. In children with intraventricular hemorrhage grade 4 with parenchymal hemorrhage, the outcomes in the group not requiring intervention were better than those in the groups requiring intervention, whereas in children with intraventricular hemorrhage grade 3 without parenchymal hemorrhage, there were no differences in the outcomes among the three groups with and without intervention. For the subjects who had undergone the same intervention, the outcomes in children with intraventricular hemorrhage grade 4 were worse than those in children with intraventricular hemorrhage grade 3. The outcomes in the children with surgical intervention only correlated with the grade of intraventricular hemorrhage. From these findings, we concluded that the outcomes in children with posthemorrhagic hydrocephalus were far more affected by the existence or extent of parenchymal hemorrhage than by the hydrocephalic process, which was suggested to be effectively controlled by the intervention.

Abstract
OBJECTIVE Currently, the timing and volume of cerebrospinal fluid (CSF) drainage are determined by subjective clinical findings in infants with posthemorrhagic hydrocephalus. The aim of this study was to determine whether measurement of the resistive index is useful for management of CSF drainage in these infants. METHODS We measured the resistive index in the anterior cerebral artery (RI-ACA) by using pulsed Doppler sonography before and after lumbar or subcutaneous ventricular catheter reservoir punctures in 7 infants with posthemorrhagic hydrocephalus. RESULTS The increased RI-ACA values (mean +/- SD, 0.86 +/- 0.04; range, 0.80-0.89) decreased significantly (0.76 +/- 0.05; 0.64-0.83) after removal of CSF at a rate of 5 to 10 mL/kg (P <.0001). CONCLUSIONS We suggest that measurement of the RI-ACA may be useful for evaluating the efficacy of CSF drainage and to determine how much CSF should be removed in hydrocephalic infants.

Abstract
OBJECT The object of this study is to demonstrate the delayed occurrence of aqueductal stenosis in preterm infants who have suffered from intraventricular hemorrhage (IVH) and to try to explain the mechanisms of this stenosis. METHOD From January 1996 to June 2002, 1,046 premature infants were admitted to our institution. Thirty-six neonates suffered from grade 3 or 4 intraventricular hemorrhage (Papile grading), of whom 16 died. Twenty patients survived and a ventriculoperitoneal shunt was inserted in 7 infants. Four patients underwent a neuroendoscopic third ventriculostomy. Follow-up was carried out, twice a month during the first 2 months and subsequently twice a year. CONCLUSION In 2 children NTV was an effective treatment for hydrocephalus with an average follow-up of 29 months. The specific pattern concerning these patients is the long delay before obstructive hydrocephalus and the visualization of de novo obstruction with MRI. The biological explanation must be investigated.
