Abstract
OBJECTIVE To (1) describe differences in types and timing of interventions, (2) report short-term outcomes and (3) describe differences among centres from a large national cohort of preterm infants with post-haemorrhagic hydrocephalus (PHH). DESIGN Cohort study of the Children's Hospitals Neonatal Database from 2010 to 2022. SETTING 41 referral neonatal intensive care units (NICUs) in North America. PATIENTS Infants born before 32 weeks' gestation with PHH defined as acquired hydrocephalus with intraventricular haemorrhage. INTERVENTIONS (1) No intervention, (2) temporising device (TD) only, (3) initial permanent shunt (PS) and (4) TD followed by PS (TD-PS). MAIN OUTCOME MEASURES Mortality and meningitis. RESULTS Of 3883 infants with PHH from 41 centres, 36% had no surgical intervention, 16% had a TD only, 19% had a PS only and 30% had a TD-PS. Of the 46% of infants with TDs, 76% were reservoirs; 66% of infants with TDs required PS placement. The percent of infants with PHH receiving ventricular access device placement differed by centre, ranging from 4% to 79% (p<0.001). Median chronological and postmenstrual age at time of TD placement were similar between infants with only TD and those with TD-PS. Infants with TD-PS were older and larger than those with only PS at time of PS placement. Death before NICU discharge occurred in 12% of infants, usually due to redirection of care. Meningitis occurred in 11% of the cohort. CONCLUSIONS There was significant intercentre variation in rate of intervention, which may reflect variability in care or referral patterns. Rate of PS placement in infants with TDs was 66%.

Abstract
PURPOSE Intraventricular hemorrhage (IVH) of prematurity can lead to hydrocephalus, sometimes necessitating permanent cerebrospinal fluid (CSF) diversion. We sought to characterize the relationship between head circumference (HC) and ventricular size in IVH over time to evaluate the clinical utility of serial HC measurements as a metric in determining the need for CSF diversion. METHODS We included preterm infants with IVH born between January 2000 and May 2020. Three measures of ventricular size were obtained: ventricular index (VI), Evan's ratio (ER), and frontal occipital head ratio (FOHR). The Pearson correlations (r) between the initial (at birth) paired measurements of HC and ventricular size were reported. Multivariable longitudinal regression models were fit to examine the HC:ventricle size ratio, adjusting for the age of the infant, IVH grade (I/II vs. III/IV), need for CSF diversion, and sex. RESULTS A total of 639 patients with an average gestational age of 27.5 weeks were included. IVH grade I/II and grade III/IV patients had a positive correlation between initial HC and VI (r = 0.47, p < 0.001 and r = 0.48, p < 0.001, respectively). In our longitudinal models, patients with a low-grade IVH (I/II) had an HC:VI ratio 0.52 higher than those with a high-grade IVH (p-value < 0.001). Patients with low-grade IVH had an HC:ER ratio 12.94 higher than those with high-grade IVH (p-value < 0.001). Patients with low-grade IVH had a HC:FOHR ratio 12.91 higher than those with high-grade IVH (p-value < 0.001). Infants who did not require CSF diversion had an HC:VI ratio 0.47 higher than those who eventually did (p < 0.001). Infants without CSF diversion had an HC:ER ratio 16.53 higher than those who received CSF diversion (p < 0.001). Infants without CSF diversion had an HC:FOHR ratio 15.45 higher than those who received CSF diversion (95% CI (11.34, 19.56), p < 0.001). CONCLUSIONS There is a significant difference in the ratio of HC:VI, HC:ER, and HC:FOHR size between patients with high-grade IVH and low-grade IVH. Likewise, there is a significant difference in HC:VI, HC:ER, and HC:FOHR between those who did and did not have CSF diversion. The routine assessments of both head circumference and ventricle size by ultrasound are important clinical tools in infants with IVH of prematurity.

Abstract
OBJECTIVE To systematically assess white matter injury (WMI) in preterm infants with posthemorrhagic ventricular dilatation (PHVD) using a high-threshold intervention strategy. STUDY DESIGN This retrospective analysis included 85 preterm infants (≤34 weeks of gestation) with grade 2-3 germinal matrix-intraventricular hemorrhage. Cranial ultrasound (cUS) scans were assessed for WMI and ventricular width and shape. Forty-eight infants developed PHVD, 21 of whom (intervention group) underwent cerebrospinal fluid drainage according to a predefined threshold (ventricular index ≥p97+4 mm or anterior horn width >10 mm, and the presence of frontal horn ballooning). The other 27 infants underwent a conservative approach (non-intervention group). The two PHVD groups were compared regarding ventricular width at two stages: the worst cUS for the non-intervention group (scans showing the largest ventricular measurements) versus pre-intervention cUS in the intervention group, and at term equivalent age. WMI was classified as normal/mild, moderate and severe. RESULTS The intervention group showed significantly larger ventricular index, anterior horn width and thalamo-occipital diameter than the non-intervention group at the two timepoints. Moderate and severe WMI were more frequent in the infants with PHVD (p<0.001), regardless of management (intervention or conservative management). There was a linear relationship between the severity of PHVD and WMI (p<0.001). CONCLUSIONS Preterm infants with PHVD who undergo a high-threshold intervention strategy associate an increased risk of WMI.

Abstract
UNLABELLED To establish the cross-sectional reference values of cerebral ventricular size for the Chinese newborns by the most correlated explanatory variables. The anterior horn width (AHW), thalamo-occipital distance (TOD), and ventricular index (VI) were collected prospectively from 1- to 7-day neonates without potential neurological problems. All neonates were delivered or treated at the Hunan Provincial Maternal and Child Health Care Hospital or Second Xiangya Hospital of Central South University between February and August 2021. The most correlated explanatory variables were identified with the max-min normalization and multiple regression. The reference values were then established based on the above variables. Additionally, intraclass correlation coefficients (ICC) were applied to evaluate the reliability of the overall data collection process. This prospective study consisted of 1848 neonates. The AHW was most highly correlated with GA; the TOD and VI were most strongly correlated with birth weight. All the foregoing correlations were positive ones. Heteroscedasticity and influential points existed in both TOD and VI. The ICCAHW was the largest to a specific rater or between raters, the ICCTOD the second largest, and the ICCVI the smallest. CONCLUSIONS We recommend using the GA-based AHW reference values and birth weight-based TOD and VI ones. We also present a comparison of GA-based upper limits from all available reference intervals. Moreover, we determine that measurement errors are the primary cause of influential points and heteroscedasticity in TOD and VI studies and infer that the studies of TOD and VI are vulnerable to them. WHAT IS KNOWN • Reference values of infantile cerebral ventricles are vital in diagnosing and treating cerebral ventricular dilatation. • Precursors established gestational age-based reference values subjectively. WHAT IS NEW • We set cross-sectional reference values based on the most correlated variables for Chinese neonates and compared all available gestational age-based upper limits. • Influential points and heteroscedasticity mainly caused by measurement errors are common in TOD and VI studies.

Abstract
Neurosonography has become an essential tool for diagnosis and serial monitoring of preterm brain injury. Preterm infants are at significantly higher risk of hypoxic-ischemic injury, intraventricular hemorrhage, periventricular leukomalacia and post-hemorrhagic hydrocephalus. Neonatologists have become increasingly dependent on neurosonography to initiate medical and surgical interventions because it can be used at the bedside. While brain MRI is regarded as the gold standard for detecting preterm brain injury, neurosonography offers distinct advantages such as its cost-effectiveness, diagnostic utility and convenience. Neurosonographic signatures associated with poor long-term outcomes shape decisions regarding supportive care, medical or behavioral interventions, and family members' expectations. Within the last decade substantial progress has been made in neurosonography techniques, prompting an updated review of the topic. In addition to the up-to-date summary of neurosonography, this review discusses the potential roles of emerging neurosonography techniques that offer new functional insights into the brain, such as superb microvessel imaging, elastography, three-dimensional ventricular volume assessment, and contrast-enhanced US.

Abstract
OBJECTIVE Efforts directed at mitigating neurological disability in preterm infants with intraventricular hemorrhage (IVH) and post hemorrhagic hydrocephalus (PHH) are limited by a dearth of quantifiable metrics capable of predicting long-term outcome. The objective of this study was to examine the relationships between candidate cerebrospinal fluid (CSF) biomarkers of PHH and neurodevelopmental outcomes in infants undergoing neurosurgical treatment for PHH. STUDY DESIGN Preterm infants with PHH were enrolled across the Hydrocephalus Clinical Research Network. CSF samples were collected at the time of temporizing neurosurgical procedure (n = 98). Amyloid precursor protein (APP), L1CAM, NCAM-1, and total protein (TP) were compared in PHH versus control CSF. Fifty-four of these PHH subjects underwent Bayley Scales of Infant Development-III (Bayley-III) testing at 15-30 months corrected age. Controlling for false discovery rate (FDR) and adjusting for post-menstrual age (PMA) and IVH grade, Pearson's partial correlation coefficients were used to examine relationships between CSF proteins and Bayley-III composite cognitive, language, and motor scores. RESULTS CSF APP, L1CAM, NCAM-1, and TP were elevated in PHH over control at temporizing surgery. CSF NCAM-1 was associated with Bayley-III motor score (R = -0.422, p = 0.007, FDR Q = 0.089), with modest relationships noted with cognition (R = -0.335, p = 0.030, FDR Q = 0.182) and language (R = -0.314, p = 0.048, FDR Q = 0.194) scores. No relationships were observed between CSF APP, L1CAM, or TP and Bayley-III scores. FOHR at the time of temporization did not correlate with Bayley-III scores, though trends were observed with Bayley-III motor (p = 0.0647 and R = -0.2912) and cognitive scores (p = 0.0506 and R = -0.2966). CONCLUSION CSF NCAM-1 was associated with neurodevelopment in this multi-institutional PHH cohort. This is the first report relating a specific CSF protein, NCAM-1, to neurodevelopment in PHH. Future work will further investigate a possible role for NCAM-1 as a biomarker of PHH-associated neurological disability.

Abstract
Advances in medical care have led to more premature babies surviving the neonatal period. In these babies, germinal matrix haemorrhage (GMH), intraventricular haemorrhage (IVH) and posthaemorrhagic ventricular dilatation (PHVD) are the most important determinants of long-term cognitive and developmental outcomes. In this review, we discuss current neurosurgical management of IVH and PHVD, including the importance of early diagnosis of PHVD, thresholds for intervention, options for early management through the use of temporising measures and subsequent definitive CSF diversion. We also discuss treatment options for the evolving paradigm to manage intraventricular blood and its breakdown products. We review the evidence for techniques such as drainage, irrigation, fibrinolytic therapy (DRIFT) and neuroendoscopic lavage in the context of optimising cognitive, neurodevelopmental and quality of life outcomes in these premature infants.

Abstract
Germinal matrix-intraventricular-intraparenchymal hemorrhage (GMH-IVH-IPH) is a major complication of very preterm births before 32 weeks of gestation (WG). Despite progress in clinical management, its incidence remains high before 27 WG. In addition, severe complications may occur such as post-hemorrhagic hydrocephalus and/or periventricular intraparenchymal hemorrhage. IVH is strongly associated with subsequent neurodevelopmental disabilities. For this review, an automated literature search and a clustering approach were applied to allow efficient filtering as well as topic clusters identification. We used a programmatic literature search for research articles related to intraventricular hemorrhage in preterms that were published between January 1990 and February 2020. Two queries ((Intraventricular hemorrhage) AND (preterm)) were used in PubMed. This search resulted in 1093 articles. The data manual curation left 368 documents that formed 12 clusters. The presentation and discussion of the clusters provide a comprehensive overview of existing data on the pathogenesis, complications, neuroprotection and biomarkers of GMH-IVH-IPH in very preterm infants. Clinicians should consider that the GMH-IVH-IPH pathogenesis is mainly due to developmental immaturity of the germinal matrix and cerebral autoregulation impairment. New multiomics investigations of intraventricular hemorrhage could foster the development of predictive biomarkers for the benefit of very preterm newborns.

Abstract
BACKGROUND Post-haemorrhagic ventricular dilatation can be measured accurately by MRI. However, two-dimensional (2-D) cranial US can be used at the bedside on a daily basis. OBJECTIVE To assess whether the ventricular volume can be determined accurately using US. MATERIALS AND METHODS We included 31 preterm infants with germinal matrix intraventricular haemorrhage. Two-dimensional cranial US images were acquired and the ventricular index, anterior horn width and thalamo-occipital distance were measured. In addition, cranial MRI was performed. The ventricular volume on MRI was determined using a previously validated automatic segmentation algorithm. We obtained the correlation and created a linear model between MRI-derived ventricular volume and 2-D cranial US measurements. RESULTS The ventricular index, anterior horn width and thalamo-occipital distance as measured on 2-D cranial US were significantly associated with the volume of the ventricles as determined with MRI. A general linear model fitted the data best: ∛ventricular volume (ml) = 1.096 + 0.094 × anterior horn width (mm) + 0.020 × thalamo-occipital distance (mm) with R2 = 0.831. CONCLUSION The volume of the lateral ventricles of infants with germinal matrix intraventricular haemorrhage can be estimated using 2-D cranial US images by application of a model.

Abstract
PURPOSE Intraventricular hemorrhage is the most important adverse neurologic event for preterm and very low weight birth infants in the neonatal period. This pathology can lead to various delays in motor, language, and cognition development. The aim of this article is to give an overview of the knowledge in diagnosis, classification, and treatment options of this pathology. METHOD A systematic review has been made. RESULTS The cranial ultrasound can be used to identify the hemorrhage and grade it according to the modified Papile grading system. There is no standardized protocol of intervention as there are controversial results on which of the temporizing neurosurgical procedures is best and about the appropriate parameters to consider a conversion to ventriculoperitoneal shunt. However, it has been established that the most important prognosis factor is the involvement and damage of the white matter. CONCLUSION More evidence is required to create a standardized protocol that can ensure the best possible outcome for these patients.

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 a low versus a higher threshold for intervention in preterm infants with posthaemorrhagic ventricular dilatation. DESIGN Multicentre randomised controlled trial (ISRCTN43171322). SETTING 14 neonatal intensive care units in six countries. PATIENTS 126 preterm infants ≤34 weeks gestation with ventricular dilatation after grade III-IV haemorrhage were randomised to low threshold (LT) (ventricular index (VI) >p97 and anterior horn width (AHW) >6 mm) or higher threshold (HT) (VI>p97+4 mm and AHW >10 mm). INTERVENTION Cerebrospinal fluid tapping by lumbar punctures (LPs) (max 3), followed by taps from a ventricular reservoir, to reduce VI, and eventually a ventriculoperitoneal (VP) shunt if stabilisation of the VI below the p97+4 mm did not occur. COMPOSITE MAIN OUTCOME MEASURE VP shunt or death. RESULTS 19 of 64 (30%) LT infants and 23 of 62 (37%) HT infants were shunted or died (P=0.45). A VP shunt was inserted in 12/64 (19%) in the LT and 14/62 (23%) infants in the HT group. 7/12 (58%) LT infants and 1/14 (7%) HT infants required shunt revision (P<0.01). 62 of 64 (97%) LT infants and 36 of 62 (58%) HT infants had LPs (P<0.001). Reservoirs were inserted in 40 of 64 (62%) LT infants and 27 of 62 (43%) HT infants (P<0.05). CONCLUSIONS There was no significant difference in the primary composite outcome of VP shunt placement or death in infants with posthaemorrhagic ventricular dilatation who were treated at a lower versus a higher threshold for intervention. Infants treated at the lower threshold received more invasive procedures. Assessment of neurodevelopmental outcomes will provide further important information in assessing the risks and benefits of the two treatment approaches.

Abstract
BACKGROUND Intraventricular hemorrhage (IVH) is a frequent complication in extreme and very preterm births. Despite a high risk of death and impaired neurodevelopment, the precise prognosis of infants with IVH remains unclear. The objective of this study was to evaluate the rate and predictive factors of evolution to post hemorrhagic hydrocephalus (PHH) requiring a shunt, in newborns with IVH and to report their neurodevelopmental outcomes at 2 years of age. METHODS Among all preterm newborns admitted to the department of neonatalogy at Rouen University Hospital, France between January 2000 and December 2013, 122 had an IVH and were included in the study. Newborns with grade 1 IVH according to the Papile classification were excluded. RESULTS At 2-year, 18% (n = 22) of our IVH cohort required permanent cerebro spinal fluid (CSF) derivation. High IVH grade, low gestational age at birth and increased head circumference were risk factors for PHH. The rate of death of IVH was 36.9% (n = 45). The rate of cerebral palsy was 55.9% (n = 43) in the 77 surviving patients (49.4%). Risk factors for impaired neurodevelopment were high grade IVH and increased head circumference. CONCLUSION High IVH grade was strongly correlated with death and neurodevelopmental outcome. The impact of an increased head circumference highlights the need for early management. CSF biomarkers and new medical treatments such as antenatal magnesium sulfate have emerged and could predict and improve the prognosis of these newborns with PHH.

Abstract
The Hydrocephalus Association Posthemorrhagic Hydrocephalus Workshop was held on July 25 and 26, 2016 at the National Institutes of Health. The workshop brought together a diverse group of researchers including pediatric neurosurgeons, neurologists, and neuropsychologists with scientists in the fields of brain injury and development, cerebrospinal and interstitial fluid dynamics, and the blood-brain and blood-CSF barriers. The goals of the workshop were to identify areas of opportunity in posthemorrhagic hydrocephalus research and encourage scientific collaboration across a diverse set of fields. This report details the major themes discussed during the workshop and research opportunities identified for posthemorrhagic hydrocephalus. The primary areas include (1) preventing intraventricular hemorrhage, (2) stopping primary and secondary brain damage, (3) preventing hydrocephalus, (4) repairing brain damage, and (5) improving neurodevelopment outcomes in posthemorrhagic hydrocephalus.

Abstract
Intraventricular haemorrhage (IVH) is characterized by bleeding of the immature subependymal germinal matrix in preterm infants, but the pathogenesis is multifactorial. IVH and posthaemorrhagic hydrocephalus (PHH) are common causes of neonatal morbidity and mortality among preterm infants. We describe a preterm male infant who was born clinically stillbirth; became moderately severe encephalopathic. He had bilateral IVH (III right and IV left) with consequent PHH. His incredible outcome following a stormy perinatal period appears intriguing. Long-term follow-up is needed to evaluate the severity of deficits as he matures. Whether therapeutic cooling would have made a difference or not is debatable.

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
BACKGROUND Preterm birth (birth before 37 weeks of gestation) is a major problem in obstetrics and affects an estimated 15 million pregnancies worldwide annually. A history of previous preterm birth is the strongest risk factor for preterm birth, and recurrent spontaneous preterm birth affects more than 2.5 million pregnancies each year. A recent meta-analysis showed possible benefits of the use of low dose aspirin in the prevention of recurrent spontaneous preterm birth. We will assess the (cost-)effectiveness of low dose aspirin in comparison with placebo in the prevention of recurrent spontaneous preterm birth in a randomized clinical trial. METHODS/DESIGN Women with a singleton pregnancy and a history of spontaneous preterm birth in a singleton pregnancy (22-37 weeks of gestation) will be asked to participate in a multicenter, randomized, double blinded, placebo controlled trial. Women will be randomized to low dose aspirin (80 mg once daily) or placebo, initiated from 8 to 16 weeks up to maximal 36 weeks of gestation. The primary outcome measure will be preterm birth, defined as birth at a gestational age (GA) < 37 weeks. Secondary outcomes will be a composite of adverse neonatal outcome and maternal outcomes, including subgroups of prematurity, as well as intrauterine growth restriction (IUGR) and costs from a healthcare perspective. Preterm birth will be analyzed as a group, as well as separately for spontaneous or indicated onset. Analysis will be performed by intention to treat. In total, 406 pregnant women have to be randomized to show a reduction of 35% in preterm birth from 36 to 23%. If aspirin is effective in preventing preterm birth, we expect that there will be cost savings, because of the low costs of aspirin. To evaluate this, a cost-effectiveness analysis will be performed comparing preventive treatment with aspirin with placebo. DISCUSSION This trial will provide evidence as to whether or not low dose aspirin is (cost-) effective in reducing recurrence of spontaneous preterm birth. TRIAL REGISTRATION Clinical trial registration number of the Dutch Trial Register: NTR 5675 . EudraCT-registration number: 2015-003220-31.

Abstract
BACKGROUND Although in recent years the percentage of preterm infants who suffer intraventricular haemorrhage (IVH) has reduced, posthaemorrhagic hydrocephalus (PHH) remains a serious problem with a high rate of cerebral palsy and no evidence-based treatment. Survivors often have to undergo ventriculoperitoneal shunt (VPS) surgery, which makes the child permanently dependent on a valve and catheter system. This carries a significant risk of infection and the need for surgical revision of the shunt. Repeated removal of cerebrospinal fluid (CSF) by either lumbar puncture, ventricular puncture, or from a ventricular reservoir in preterm babies with IVH has been suggested as a treatment to reduce the risk of PHH development. OBJECTIVES To determine the effect of repeated cerebrospinal fluid (CSF) removal (by lumbar/ventricular puncture or removal from a ventricular reservoir) compared to conservative management, where removal is limited to when there are signs of raised intracranial pressure (ICP), on reduction in the risk of permanent shunt dependence, neurodevelopmental disability, and death in neonates with or at risk of developing posthaemorrhagic hydrocephalus (PHH). SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 3), MEDLINE via PubMed (1966 to 24 March 2016), Embase (1980 to 24 March 2016), and CINAHL (1982 to 24 March 2016). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-RCTs. SELECTION CRITERIA RCTs and quasi-RCTs that compared serial removal of CSF (via lumbar puncture, ventricular puncture, or from a ventricular reservoir) with conservative management (removing CSF only when there were symptoms of raised ICP). Trials also had to report on at least one of the specified outcomes of death, disability, or shunt insertion. DATA COLLECTION AND ANALYSIS We extracted details of the participant selection, participant allocation and the interventions. We assessed the following outcomes: VPS, death, death or shunt, disability, multiple disability, death or disability, and CSF infection. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS Four trials (five articles) met the inclusion criteria of this review; three were RCTs and one was a quasi-RCT; and included a total of 280 participants treated in neonatal intensive care units in the UK. The trials were published between 1980 and 1990. The studies were sufficiently similar regarding the research question they asked and the interventions that we could combine the trials to assess the effect of the intervention.Meta-analysis showed that the intervention produced no significant difference when compared to conservative management for the outcomes of: placement of hydrocephalus shunt (typical risk ratio (RR) 0.96, 95% confidence interval (CI) 0.73 to 1.26; 3 trials, 233 infants; I² statistic = 0%; moderate quality evidence), death (RR 0.88, 95% CI 0.53 to 1.44; 4 trials, 280 infants; I² statistic = 0%; low quality evidence), major disability in survivors (RR 0.98, 95% CI 0.81 to 1.18; 2 trials, 141 infants; I² statistic = 11%; high quality evidence), multiple disability in survivors (RR 0.9, 95% CI 0.66 to 1.24; 2 trials, 141 infants; I² statistic = 0%; high quality evidence), death or disability (RR 0.99, 95% CI 0.86 to 1.14; 2 trials, 180 infants; I² statistic = 0%; high quality evidence), death or shunt (RR 0.91, 95% CI 0.75 to 1.11; 3 trials, 233 infants; I² statistic = 0%; moderate quality evidence), and infection of CSF presurgery (RR 1.73, 95% CI 0.53 to 5.67; 2 trials, 195 infants; low quality evidence).We assessed the quality of the evidence as high for the outcomes of major disability, multiple disability, and disability or death. We rated the evidence for the outcomes of shunt insertion, and death or shunt insertion as of moderate quality as one included trial used an alternation method of randomisation. For the outcomes of death and infection of CSF presurgery, the quality of the evidence was low as one trial used an alternation method, the number of participants was too low to assess the objectives with sufficient precision, and there was inconsistency regarding the findings in the included trials regarding the outcome of infection of CSF presurgery. AUTHORS' CONCLUSIONS There was no evidence that repeated removal of CSF via lumbar puncture, ventricular puncture or from a ventricular reservoir produces any benefit over conservative management in neonates with or at risk for developing PHH in terms of reduction of disability, death, or need for placement of a permanent shunt.

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
Here, we aimed to evaluate the incidence and mortality of intraventricular hemorrhage (IVH) and post-hemorrhagic hydrocephalus (PHH) among very-low-birth-weight (VLBW) infants in Korea and assess the associated factors of PHH. This cohort study used prospectively collected data from the Korean Neonatal Network (KNN). Among 2,386 VLBW infants in the KNN database born between January 2013 and June 2014, 63 infants who died without brain ultrasonography results were excluded. Maternal demographics and neonatal clinical characteristics were assessed. The overall incidence of IVH in all the VLBW infants was 42.2% (987 of 2,323), while those of IVH grade 1, 2, 3, and 4 were 25.1%, 7.0%, 4.8%, and 5.5%, respectively. The incidence and severity of IVH showed a negatively correlating trend with gestational age and birth weight. PHH developed in 0%, 3.5%, 36.1%, and 63.8% of the surviving infants with IVH grades 1, 2, 3, and 4, respectively. Overall, in the VLBW infants, the IVH-associated mortality rate was 1.0% (24/2,323). Only IVH grade severity was proven to be an associated with PHH development in infants with IVH grades 3-4. This is the first Korean national report of IVH and PHH incidences in VLBW infants. Further risk factor analyses or quality improvement studies to reduce IVH are warranted.

Abstract
OBJECT Intraventicular hemorrhage (IVH) is a common complication of preterm birth, and the prognosis of IVH is incompletely characterized. The objective of this study was to describe the outcomes of IVH in a population-based cohort with minimal selection bias. METHODS All very preterm (≥ 30 completed weeks) patients born in the province of Nova Scotia were included in a comprehensive database. This database was screened for infants born to residents of Nova Scotia from January 1, 1993, to December 31, 2010. Among very preterm infants successfully resuscitated at birth, the numbers of infants who died, were disabled, developed cerebral palsy, developed hydrocephalus, were blind, were deaf, or had cognitive/language scores assessed were analyzed by IVH grade. The relative risk of each outcome was calculated (relative to the risk for infants without IVH). RESULTS Grades 2, 3, and 4 IVH were significantly associated with an increased overall mortality, primarily in the neonatal period, and the risk increased with increasing grade of IVH. Grade 4 IVH was significantly associated with an increased risk of disability (RR 2.00, p < 0.001), and the disability appeared to be primarily due to cerebral palsy (RR 6.07, p < 0.001) and cognitive impairment (difference in mean MDI scores between Grade 4 IVH and no IVH: -19.7, p < 0.001). No infants with Grade 1 or 2 IVH developed hydrocephalus, and hydrocephalus and CSF shunting were not associated with poorer outcomes when controlling for IVH grade. CONCLUSIONS Grades 1 and 2 IVH have much better outcomes than Grades 3 or 4, including a 0% risk of hydrocephalus in the Grade 1 and 2 IVH cohort. Given the low risk of selection bias, the results of this study may be helpful in discussing prognosis with families of very preterm infants diagnosed with IVH.

Abstract
OBJECT Intraventicular hemorrhage (IVH) and posthemorrhagic hydrocephalus (PHH) are common in premature newborns. The epidemiology of these conditions has been described, but selection bias remains a significant concern in many studies. The goal of this study was to review temporal trends in the incidence of IVH, PHH, and shunt surgery in a population-based cohort of very preterm infants with no selection bias. METHODS All very preterm infants (gestational age ≥ 20 and ≤ 30 weeks) born from 1993 onward to residents of Nova Scotia were evaluated by the IWK Health Centre's Perinatal Follow-Up Program, and were entered in a database. Infants born to residents of Nova Scotia from January 1, 1993, to December 31, 2012, were included in this study. The incidences of IVH, PHH, and shunt surgery were calculated, basic demographic information was described, and chi-square test for trends over time was determined. RESULTS Of 1334 successfully resuscitated very preterm infants who survived to their initial screening ultrasound, 407 (31%) had an IVH, and 149 (11%) had an IVH Grade 3 or 4. No patients with IVH Grade 1 or 2 developed PHH. The percentage of very preterm infants with IVH Grade 3 or 4 has significantly increased over time (p = 0.013), as have the incidence of PHH and shunt surgery (p = 0.001 and p = 0.011, respectively) in infants with Grade 3 or 4 IVH. The proportion of patients with PHH receiving a shunt has not changed over time (p = 0.813). CONCLUSIONS The increasing incidence of high-grade IVH-and PHH and shunt surgery in infants with high-grade IVH-over time is worrisome. This study identifies a number of associated factors, but further research to identify preventable and treatable causal factors is warranted.

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 Intraventricular hemorrhage (IVH) is the most common cause of hydrocephalus in the pediatric population and is particularly common in preterm infants. The decision to place a ventriculoperitoneal shunt or ventricular access device is based on physical examination findings and radiographic imaging. The authors undertook this study to determine if head circumference (HC) measurements correlated with the Evans ratio (ER) and if changes in ventricular size could be detected by HC measurements. METHODS All cranial ultrasound (CUS) reports at the authors' institution between 2008 and 2011 were queried for terms related to hydrocephalus and IVH, from which a patient cohort was determined. A review of radiology reports, HC measurements, operative interventions, and significant clinical events was performed for each patient in the study. Additional radiographic measurements, such as an ER, were calculated by the authors. Significance was set at a statistical threshold of p < 0.05 for this study. RESULTS One hundred forty-four patients were studied, of which 45 (31%) underwent CSF diversion. The mean gestational age and birth weight did not differ between patients who did and those who did not undergo CSF diversion. The CSF diversion procedures were reserved almost entirely for patients with IVH categorized as Grade III or IV. Both initial ER and HC were significantly larger for patients who underwent CSF diversion. The average ER and HC at presentation were 0.59 and 28.2 cm, respectively, for patients undergoing CSF diversion, and 0.34 and 25.2 cm for those who did not undergo CSF diversion. There was poor correlation between ER and HC measurements regardless of gestational age (r = 0.13). Additionally, increasing HC was not found to correlate with increasing ERs on consecutive CUSs (φ = -0.01, p = 0.90). Patients who underwent CSF diversion after being followed with multiple CUSs (10 of 45 patients) presented with smaller ERs and HC than those who underwent CSF diversion after a single CUS. Just prior to CSF diversion surgery, the patients who received multiple CUSs had ERs, but not HC measurements, that were similar to those in patients who underwent CSF diversion after a single CUS. CONCLUSIONS The HC measurement does not correlate with the ER or with changes in ER and therefore does not appear to be an adequate surrogate for serial CUSs. In patients who are followed for longer periods of time before CSF shunting procedures, the ER may play a larger role in the decision to proceed with surgery. Clinicians should be aware that the ER and HC are not surrogates for one another and may reflect different pathological processes. Future studies that take into account other physical examination findings and long-term clinical outcomes will aid in developing standardized protocols for evaluating preterm infants for ventriculoperitoneal shunt or ventricular access device placement.

Abstract
Object Neonatal intraventricular hemorrhage (IVH) may evolve into posthemorrhagic hydrocephalus and cause neurodevelopmental impairment. In this study, an endoscopic surgical approach directed toward the removal of intraventricular hematoma was evaluated for its safety and efficacy. Methods Between August 2010 and December 2012 (29 months), 19 neonates with posthemorrhagic hydrocephalus underwent neuro endoscopic lavage for removal of intraventricular blood remnants. During a similar length of time (29 months) from March 2008 to July 2010, 10 neonates were treated conventionally, initially using temporary CSF diversion via lumbar punctures, a ventricular access device, or an external ventricular drain. Complications and shunt dependency rates were evaluated retrospectively. Results The patient groups did not differ regarding gestational age and birth weight. In the endoscopy group, no relevant procedure-related complications were observed. After the endoscopic lavage, 11 (58%) of 19 patients required a later shunt insertion, as compared with 100% of infants treated conventionally (p < 0.05). Endoscopic lavage was associated with fewer numbers of overall necessary procedures (median 2 vs 3.5 per patient, respectively; p = 0.08), significantly fewer infections (2 vs 5 patients, respectively; p < 0.05), and supratentorial multiloculated hydrocephalus (0 vs 4 patients, respectively; p < 0.01) [corrected].Conclusions Within the presented setup the authors could demonstrate the feasibility and safety of neuro endoscopic lavage for the treatment of posthemorrhagic hydrocephalus in neonates with IVH. The nominally improved results warrant further verification in a multicenter, prospective study.

Abstract
OBJECT The aim of this study was to determine the role of endoscopic third ventriculostomy and choroid plexus cauterization (ETV/CPC) in the management of posthemorrhagic hydrocephalus of prematurity (PHHP) and to analyze which factors affect patient outcomes. METHODS This study retrospectively reviewed medical records of 27 premature infants with intraventricular hemorrhage (IVH) and hydrocephalus treated with ETV and CPC from 2008 to 2011. All patients were evaluated using MRI before the procedure to verify the anatomical feasibility of ETV/CPC. Endoscopic treatment included third ventriculostomy, septostomy, and bilateral CPC. After ETV/CPC, all patients underwent follow-up for a period of 6-40 months (mean 16.2 months). The procedure was considered a failure if the patient subsequently required a shunt. The following factors were analyzed to determine a relationship to patient outcomes: gestational age at birth, corrected age and weight at surgery, timing of surgery after birth, grade of IVH, the status of the prepontine cistern and cerebral aqueduct on MRI, need for a ventricular access device prior to the endoscopic procedure, and scarring of the prepontine cistern noted at surgery. RESULTS Seventeen (63%) of 27 patients required a shunt after ETV/CPC, and 10 patients did not require further CSF diversion. Several factors studied were associated with a higher rate of ETV/CPC failure: Grade IV hemorrhage, weight 3 kg or less and age younger than 3 months at the time of surgery, need for reservoir placement, and presence of a normal cerebral aqueduct. Two factors were found to be statistically significant: the patient's corrected gestational age of less than 0 weeks at surgery and a narrow prepontine cistern on MRI. The majority (83%) of ETV/CPC failures occurred in the first 3 months after the procedure. None of the patients had a complication directly related to the procedure. CONCLUSIONS Endoscopic third ventriculostomy/CPC is a safe initial procedure for hydrocephalus in premature infants with IVH and hydrocephalus, obviating the need for a shunt in selected patients. Even though the success rate is low (37%), the lower rate of complications in comparison with shunt treatment may justify this procedure in the initial management of hydrocephalus. As several of the studied factors have shown influence on the outcome, patient selection based on these observations might increase the success rate.

Abstract
Germinal matrix-intraventricular haemorrhage (GMH-IVH) remains a serious problem in the very and extremely preterm infant. This article reviews current methods of diagnosis, treatment and neurodevelopmental outcome in preterm infants with low-grade and severe GMH-IVH. We conclude that there is still no consensus on timing of intervention and treatment of infants with GMH-IVH, whether or not complicated by post-haemorrhagic ventricular dilatation. The discrepancies between the studies underline the need for international collaboration to define the optimal strategy for these infants.

Abstract
OBJECT The optimal management of neonatal intraventricular hemorrhage (IVH) and posthemorrhagic ventricular dilation is challenging. The importance of early treatment has been demonstrated in a recent randomized study, involving early ventricular irrigation and drainage, which showed significant cognitive improvement at 2 years. The objective of this study was to define the changes in CSF absorption capacity over time in a neonatal piglet model of IVH. METHODS Ten piglets (postnatal age 9-22 hours) underwent intraventricular injection of homologous blood. A ventricular access device was inserted 7-10 days later. Ventricular dilation was measured by ultrasonography. Serial constant flow infusion studies were performed through the access device from Week 2 to Week 8. RESULTS Seven piglets survived long term, 43-60 days, and developed ventricular dilation; this reached a maximum by Week 6. There was no significant difference in baseline intracranial pressure throughout this period. The resistance to CSF outflow, R(out), increased from 63.5 mm Hg/ml/min in Week 2 to 118 mm Hg/ml/min in Week 4. Although R(out) decreased after Week 5, the ventriculomegaly persisted. CONCLUSIONS In this neonatal piglet model, reduction in CSF absorptive capacity occurs early after IVH and accompanies progressive and irreversible ventriculomegaly. This suggests that early treatment of premature neonates with IVH is desirable.

Abstract
OBJECT Although survival for extremely low gestational age newborns (ELGANs) has improved in the past 3 decades, these infants remain prone to complications of prematurity, including intraventricular hemorrhage (IVH). The authors reviewed the outcomes for an entire cohort of ELGANs who suffered severe IVH at their institution during the past 12 years to gain a better understanding of the natural history of IVH and frequency of ventriculoperitoneal (VP) shunt placement in this population. METHODS Data from the neonatal ICU (NICU) database, neurosurgery operative log, and medical records were used to identify and follow up all ELGANs who suffered a severe IVH between 1997 and 2008. Trends between Period 1 (1997-2001) and Period 2 (2004-2008) were analyzed using the Pearson chi-square test. RESULTS Between 1997 and 2008, 1335 ELGANs were admitted to the NICU at the authors' institution within 3 days of birth, and 111 (8.3%) of these infants suffered a severe IVH. Survival to 2 years, incidence of severe IVH, neonatal risk factors (gestational age, birth weight, and incidence of necrotizing enterocolitis), ventriculomegaly on cranial ultrasonography, and use of serial lumbar punctures for symptomatic hydrocephalus were all stable. Infants from period 2 had a significantly lower incidence of bronchopulmonary dysplasia and sepsis than infants from Period 1 (both p < 0.001). All ELGANs with severe IVH and ventriculomegaly underwent long-term follow-up to identify shunt status at late follow-up. Twenty-two ELGANs (20%) with severe IVH required a temporary ventriculosubgaleal (VSG) shunt. Three infants with VSG shunts showed spontaneous hydrocephalus resolution, and 2 infants died of unrelated causes during the neonatal admission. The temporary VSG shunt complication rate was 20% (12% infection and 8% malfunction). Sixteen percent of all ELGANs (18 of 111) with severe IVH eventually required permanent ventricular shunt insertion. Six (35%) of 17 infants with a permanent VP shunt required at least 1 permanent shunt revision during the 1st year. The proportion of ELGANs with severe IVH who required a temporary VSG (35%) or permanent VP shunt (30%) during Period 1 decreased by more than 60% in Period 2 (10% [p = 0.005] and 8.3% [p = 0.009], respectively). CONCLUSIONS The authors report for the first time a marked reduction over the past 12 years in the proportion of ELGANs with severe IVH who required surgical intervention for hydrocephalus. Using the NICU database, the authors were able to identify and follow all ELGANs with severe IVH and ventriculomegaly. They speculate that the reduction in ventricular shunt rate results from improved neonatal medical care, including reduced infection, improved bronchopulmonary dysplasia, and postnatal steroid avoidance, which may aid innate repair mechanisms. Multicenter prospective trials and detailed analyses of NICU parameters of neonatal well-being are needed to understand how perinatal factors influence the propensity to require ventricular shunting.

Abstract
OBJECTIVE This study aims to evaluate effects and complications of the implantation of Ommaya reservoir in premature infants with posthemorrhagic hydrocephalus (PHH). METHODS The effects and complications of the implantation of Ommaya reservoir in seven premature infants with PHH were retrospectively analyzed. Intracapsular puncture of the reservoir was performed for draining cerebrospinal fluid. RESULTS Seven extremely low-weight premature infants with PHH (birthweight less than 1,000 g) were treated with the placement of an Ommaya reservoir. Ommaya reservoirs in five infants were removed, but were retained in two infants. Two premature infants had to undergo ventriculoperitoneal (VP) shunt. Postsurgical major complications (including skin dehiscence, cerebrospinal fluid (CSF) infection, ventricular hemorrhage, and CSF leak) occurred in 57% of all patients. Three infants of skin dehiscence and CSF leak occurred. Two infants of CSF infection occurred, as well as one clinically significant secondary hemorrhage. Six infants survived, and one died. CONCLUSION The implantation of Ommaya reservoir is a cautious option of treating low-weight premature infants with PHH because of a relatively high complication rate. However, VP shunt surgery may be avoided in some infants.

Abstract
OBJECT There is little consensus regarding the indications for surgical CSF diversion (either with implanted temporizing devices [reservoir or subgaleal shunt] or shunt alone) in preterm infants with posthemorrhagic hydrocephalus. The authors determined clinical and neuroimaging factors associated with the use of surgical CSF diversion among neonates with intraventricular hemorrhage (IVH), and describe variations in practice patterns across 4 large pediatric centers. METHODS The use of implanted temporizing devices and conversion to permanent shunts was examined in a consecutive sample of 110 neonates surgically treated for IVH related to prematurity from the 4 clinical centers of the Hydrocephalus Clinical Research Network (HCRN). Clinical, neuroimaging, and so-called processes of care factors were analyzed. RESULTS Seventy-three (66%) of the patients underwent temporization procedures, including 50 ventricular reservoir and 23 subgaleal shunt placements. Center (p < 0.001), increasing ventricular size (p = 0.04), and bradycardia (p = 0.07) were associated with the use of an implanted temporizing device, whereas apnea, occipitofrontal circumference (OFC), and fontanel assessments were not. Implanted temporizing devices were converted to permanent shunts in 65 (89%) of the 73 neonates. Only a full fontanel (p < 0.001) and increased ventricular size (p = 0.002) were associated with conversion of the temporizing devices to permanent shunts, whereas center, OFCs, and clot characteristics were not. CONCLUSIONS Considerable center variability exists in neurosurgical approaches to temporization of IVH in prematurity within the HCRN; however, variation between centers is not seen with permanent shunting. Increasing ventricular size-rather than classic clinical findings such as increasing OFCs-represents the threshold for either temporization or shunting of CSF.

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
PURPOSE The purpose of this study is to perform a population-based, very long-term follow-up of adults who had been shunt treated for hydrocephalus in infancy. METHODS The 72 children with hydrocephalus born in 1967-1978 in western Sweden, who had participated in a follow-up at school age, were re-examined at 30-43 years of age. The 29 with mental retardation were described in terms of developmental level and survival, whereas the remaining 43 were invited to take part in a follow-up and 28 accepted. The assessments included a semi-structured interview pertaining to medical issues, academic achievements and social function. RESULTS Six children had died, i.e. a mortality rate of 8%. Mental retardation was present in 29 (40%), severe (IQ <50) in 13 and mild (IQ 50-70) in 16. Four of the 28 (14%) had cerebral palsy and 8 (28%) had other motor problems. Five (18%) had epilepsy and nine (32%) had visual impairments. A total of 20 (71%) reported some kind of health problem. Repeated revisions of the shunt had been performed in 23 (82%). Many worried about their shunt and requested a systematic medical follow-up. Nineteen subjects (68%) lived with a partner and 16 (57%) were parents. The majority had completed secondary school and 9 (32%) had completed university studies, while 18 (64%) worked full time, equal to the general population. CONCLUSION In general, the group of normally gifted individuals with hydrocephalus, who had been shunt treated during infancy, was functioning well as adults and participated in society to the same extent as other people.

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
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 We aimed to evaluate neurodevelopmental and growth outcomes among extremely low birth weight infants who had severe intraventricular hemorrhage that required shunt insertion compared with infants without shunt insertion. METHODS Infants who were born in 1993-2002 with birth weights of 401 to 1000 g were enrolled in a very low birth weight registry at medical centers that participate in the National Institute of Child Health and Human Development Neonatal Research Network, and returned for follow-up at 18 to 22 months' corrected age were studied. Eighty-two percent of survivors completed follow-up, and 6161 children were classified into 5 groups: group 1, no intraventricular hemorrhage/no shunt (n = 5163); group 2, intraventricular hemorrhage grade 3/no shunt (n = 459); group 3, intraventricular hemorrhage grade 3/shunt (n = 103); group 4, intraventricular hemorrhage grade 4/no shunt (n = 311); and group 5, intraventricular hemorrhage grade 4/shunt (n = 125). Group comparisons were evaluated with chi(2) and Wilcoxon tests, and regression models were used to compare outcomes after adjustment for covariates. RESULTS Children with severe intraventricular hemorrhage and shunts had significantly lower scores on the Bayley Scales of Infant Development IIR compared with children with no intraventricular hemorrhage and with children with intraventricular hemorrhage of the same grade and no shunt. Infants with shunts were at increased risk for cerebral palsy and head circumference at the <10th percentile at 18 months' adjusted age. Greatest differences were observed between children with shunts and those with no intraventricular hemorrhage on these outcomes. CONCLUSIONS This large cohort study suggests that extremely low birth weight children with severe intraventricular hemorrhage that requires shunt insertion are at greatest risk for adverse neurodevelopmental and growth outcomes at 18 to 22 months compared with children with and without severe intraventricular hemorrhage and with no shunt. Long-term follow-up is needed to determine whether adverse outcomes persist or improve over time.

Abstract
OBJECTIVE The purpose of this study was to monitor incidence and outcome in children with hydrocephalus. MATERIALS AND METHODS This is a population-based prospective study of all the children with hydrocephalus born in western Sweden in 1999-2002. Etiological and clinical information was collected from records, neuroimaging and ophthalmological examinations. Comparisons with 208 children born in 1989-1998 were made. RESULTS The incidence was 0.66 per 1,000 live births, 0.48 for infantile hydrocephalus and 0.18 for hydrocephalus associated with myelomeningocele. The corresponding rates for 1989-1998 were 0.82, 0.49 and 0.33. Ventriculo-peritoneal shunt treatment was used in 42 of the 54 children and endoscopic third ventriculostomy in 12. Revisions were performed in 33 (61%). Neurological impairments were present in 63%, and they were more common in children born preterm than in those born at term. The radiological extent of parenchymal lesions correlated significantly with outcome. Ophthalmological abnormalities were found in 80%, including visual impairment in one third. CONCLUSION The incidence of post-haemorrhagic hydrocephalus in children born extremely preterm increased; a group running a high risk of neurological sequelae. Ophthalmological abnormalities were frequent and need to be assessed in all children with hydrocephalus. The high rate of morbidity and complications necessitates the further development of preventive and treatment methods.

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
BACKGROUND Severe intrauterine hypoxia-ischemia and acidemia may lead to a disturbed neurodevelopment. OBJECTIVES To study the effects of acidemia at birth on neurodevelopment in preterm and full-term neonates. SUBJECTS AND METHODS Short- and long-term outcome were studied retrospectively in 44 inborn preterms and 95 full-terms with severe acidemia at birth defined as a pH of the umbilical artery <7.00. Outcome was compared with 67 preterm and 90 full-term non-acidemic neonates (pH>7.15). Intraventricular hemorrhage (preterms) or seizures (both preterms and full-terms) were considered an adverse short-term outcome. Neonatal death, cerebral palsy or neurodevelopmental delay were considered an adverse long-term outcome. RESULTS Severe intraventricular hemorrhage (IVH) occurred in 5 of the 44 (11%) acidemic preterms and in none of the 67 (0%) non-acidemic preterms (p<0.01). Seizures were observed in 9 of the 44 (20%) and 11 of the 95 (12%) acidemic preterms and full-terms, respectively, and in none of the 67 (0%) and 1 of the 90 (1%) non-acidemic preterms and full-terms, respectively (p<0.001 for preterms, p<0.01 for full-terms). Nine preterms (6 acidemic, 3 non-acidemic) and 2 full-terms (both acidemic) died in the neonatal period. Adverse long-term outcome occurred in 32% of the acidemic preterms, in 21% of the non-acidemic preterms, in 7% of the acidemic full-terms and in 7% of the non-acidemic full-terms. CONCLUSIONS Acidemia at birth increased the occurrence of severe IVH in preterm neonates and seizures in both preterm and full-term neonates. However, no significant effect of acidemia on long-term outcome could be demonstrated.
