Ventriculoperitoneal shunt infection rate and other associated complications of VP shunt insertion in Abuja, Nigeria. World Neurosurg X 2024; 23:100332. [PMID: 38533233 PMCID: PMC10963310 DOI: 10.1016/j.wnsx.2024.100332] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 01/19/2024] [Accepted: 01/21/2024] [Indexed: 03/28/2024] Open
Abstract
Background Complications associated with ventriculoperitoneal shunt insertion constitute a significant cause of morbidity and mortality among hydrocephalus patients. Despite this, VP shunt placement has remained the mainstay of treatment for hydrocephalus. The aim of this study is to evaluate the complications of VP shunt surgery in our environment and to identify the risk factors associated with it. Methodology Patients who had VP shunt surgery over a period of two years (Jan 2015-December 2016) were evaluated retrospectively by reviewing their hospital records. The patients' demography, aetiology and clinical presentation of the hydrocephalus, and complications were analysed using SPSS version 26.0. Results were presented in tables and figures. Results A total of 69 patients who had VP shunt over the study period had complete medical records available for review. Their age ranged between 2days and 68years with a male to female ratio of 1.8:1. Overall complication rate was 30.4%. Shunt malfunction (11.5%) and shunt infection (7.2%) were the commonest complications recorded. Late presentation was the most important risk factor for shunt complications. Conclusion The rate of shunt complications seen in this study compares fairly with studies in other parts of the world.

[PMID: 38893666 PMCID: PMC11172121 DOI: 10.3390/diagnostics14111141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 05/24/2024] [Accepted: 05/29/2024] [Indexed: 06/21/2024] Open
Abstract
Two patients with CSF shunting systems exhibited symptoms of altered intracranial pressure. Initial neuroimaging led to misinterpretation, but integrating clinical history and follow-up imaging revealed the true diagnosis. In the first case, reduced ventricular size was mistaken for CSF overdrainage, while the actual problem was increased intracranial pressure, as seen in slit ventricle syndrome. In the second case, symptoms attributed to intracranial hypertension were due to CSF overdrainage causing tonsillar displacement and hydrocephalus. Adjusting the spinoperitoneal shunt pressure resolved symptoms and imaging abnormalities. These cases highlight the necessity of correlating clinical presentation with a deep understanding of CSF dynamics in shunt assessments.

Abstract
PURPOSE Hydrocephalus is a brain disease prevalent in the pediatric population that presents complex pathophysiology and multiple etiologies. The best treatment is still ventricular shunting. Mechanical obstruction is the most frequent complication, but the resulting pathological effects are still unknown. OBJECTIVE Evaluation and comparison of clinical, histopathological, and immunohistochemical aspects in the acute phase of experimental hydrocephalus induced by kaolin, after treatment with adapted shunt, and after shunt obstruction and posterior disobstruction. METHODS Wistar rats aged 7 days were used and divided into 4 groups: control group without kaolin injection (n = 6), untreated hydrocephalic group (n = 5), hydrocephalic group treated with ventriculosubcutaneous shunt (DVSC) (n = 7), and hydrocephalic group treated with shunt, posteriorly obstructed and disobstructed (n = 5). The animals were submitted to memory and spatial learning evaluation through the Morris water maze test. The rats were sacrificed at 28 days of age and histological analysis of the brains was performed with luxol fast blue, in addition to immunohistochemical analysis in order to evaluate reactive astrocytosis, inflammation, neuronal labeling, and apoptotic activity. RESULTS The group with shunt obstruction had worse performance in memory tests. Reactive astrocytosis was more evident in this group, as was the inflammatory response. CONCLUSIONS Obstruction of the shunt results in impaired performance of behavioral tests and causes irreversible histopathological changes when compared to findings in the group with treated hydrocephalus, even after unblocking the system. The developed model is feasible and efficient in simulating the clinical context of shunt dysfunction.

Abstract
BACKGROUND At Red Cross War Memorial Children's Hospital (RCCH), it is the preferred practice to use non-ventriculoperitoneal (non-VP) shunts when the peritoneum is ineffective or contraindicated for cerebrospinal fluid (CSF) diversion and when endoscopy is not an option. The objective of this study is to evaluate the clinical course of patients having undergone these procedures. METHOD A single-centre retrospective review at RCCH wherein 43 children with a total of 59 episodes of non-VP shunt placement over a 12-year period were identified for inclusion. RESULTS Twenty-five ventriculoatrial (VA) and 32 ventriculopleural (VPL) shunts were analysed with a median age at insertion of 2.9 (0.3-14.9) and 5.3 years (0.5-13.4), respectively. The median number of previous shunt procedures prior to VA or VPL shunt insertion was 6.0 (2-28) versus 4.5 (2-17), respectively. Three VA (12.0%) and three VPL (9.4%) shunt patients were lost to follow-up. Of those remaining, 10 VA shunts (45.5%) compared to 19 (65,5%) VPL shunts required revision. One ventriculovesical shunt and one ventriculocholecystic shunt were placed in the same patient after 21 and 25 shunt-related procedures, respectively, and both were revised within 3 weeks of insertion. Median shunt survival was 8 months longer for the VA compared to the VPL shunts, being 13.5 (0-67) and 5 months (0-118), respectively. Complications for VA shunts were low, with the overall shunt sepsis rate in the VA group at 4% (n = 1) compared to 15.6% (n = 5) in the VPL group. CONCLUSION Our findings support that VA and VPL shunts are acceptable second-line options in an already compromised group of patients where safe treatment options are limited, provided attention is paid to the technical details specific to their placement.

Abstract
PURPOSE CSF diversion is a recognised intervention in idiopathic intracranial hypertension (IIH), particularly in the presence of vision-threatening papilledema. Although ventriculo-atrial (VA) shunt insertion is a routine neurosurgical procedure, ventriculoperitoneal and lumboperitoneal shunts have been mostly used in this particular indication. This study aims to look at a single centre's experience with VA shunts in idiopathic intracranial hypertension (IIH). METHODS Retrospective case series with a review of electronic records over a 10-year period; exclusion criteria were duplication of same shunt insertion, no VA shunt insertion, paediatric patients and indication other than IIH. Notes were reviewed for demographics, shunt survival (defined by time prior to revision) and reasons for revision. RESULTS Eight VA shunt procedures were identified in 6 patients (mean age at insertion 34 ± 10 years) with a mean follow-up of 58 ± 25 months. All shunts were secondary procedures; 2 revisions from lumbo-pleural, 2 from ventriculopleural, 2 from ventriculoatrial and one each from ventriculoperitoneal and combined lumbo-/ventriculoperitoneal. At 50 months, 75% of VA shunts had survived, compared to only 58.3% of VPleural shunts in patients with IIH. Revisions were required due to acute intracranial bleed (1 case)-revised at day 1, and thrombus at distal site (1 case)-revised at day 57. Both shunts were later reinserted. From the latest clinic letters, all patients had their treatment optimised with this procedure, although only two patients had documented resolved papilloedema post-procedure. CONCLUSIONS Ventriculo-atrial shunts are a safe and efficacious alternative option for CSF diversion in IIH. In this series, only 1 shunt was revised for a VA shunt-specific complication.

Abstract
Intracardiac migration is a rare complication of ventriculoperitoneal shunt insertion. Only 15 cases have been reported, 7 of which were paediatric cases, treated with techniques including interventional radiography, open thoracotomies and direct extraction through the initial shunt incision. The authors report the youngest case of intracardiac shunt migration complicated by significant coiling and knotting within the cardiac chambers and pulmonary vasculature. Migration likely began when the SVC was pierced during initial shunt placement and progressed due to negative intrathoracic pressure. Extrusion was achieved combining thoracoscopic endoscopy, interventional fluoroscopy screening and a posterolateral neck incision with uncoiling of the shunt via a Seldinger guide wire. This offered a minimally invasive solution with rapid post-operative recovery.

Abstract
BACKGROUND Ventricular shunts are one of the most frequent techniques used for the management of hydrocephalus. The ventriculoperitoneal shunt (VPS) is the most commonly performed procedure, and the ventriculoatrial shunt (VAS) is the second option in most medical centers. The main objective of this study is to introduce and describe a surgical approach for VAS outlining our experience and comparing it with traditional shunting techniques. METHODS In this retrospective cohort comparison study, we included patients with hydrocephalus treated with a surgical procedure between January 2010 and February 2021 at a single academic institution. We categorized the procedures into two groups: patients with VPS and conventional VAS grouped together into the conventional technique (CT) group, and the second group was patients with whom we performed VAS with complete internal jugular vein occlusion (IJVOT). We compared the surgical time, postoperative complications, and occurrence of shunt failure among the groups by performing univariate analysis using the Fisher exact test. RESULTS Out of the 106 patients included in the analysis, IJVOT was performed in 66 patients, and CT in 40 patients. The median surgical time was 60 min (IQR 60-90) for IJVOT versus 100 min (IQR 60-120) for CT (p < 0.01). In the follow-up a month after the procedure, 83.3% of patients with IJVOT and 62.5% of patients with CT did not require shunt removal or shunt revision (p < 0.01). Shunt revision rates were 12.5% and 1.5% for CT while 1.5% and 2.5% for IJVOT at 1 and 6 months after the procedure. CONCLUSION Our findings demonstrate that VAS with IJVOT is a safe method that exhibited shorter surgical times and outcomes comparable to CT. However, since the present study represents the first cohort evaluating IJVOT, it is imperative to conduct larger prospective studies, along with clinical trials, to fully explore and establish efficacy, long-term outcomes, and an in-depth comparison among shunting techniques.

Abstract
BACKGROUND AND OBJECTIVES Ventriculoperitoneal shunt (VPS) is usually the primary choice for cerebrospinal fluid shunting for most neurosurgeons, while ventriculoatrial shunt (VAS) is a second-line procedure because of historical complications. Remarkably, there is no robust evidence claiming the superiority of VPS over VAS. Thus, we aimed to compare both procedures through a meta-analysis. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, the authors systematically searched the literature for articles comparing VAS with VPS. The included articles had to detail one of the following outcomes: revisions, infections, shunt-related mortality, or complications. In addition, the cohort for each shunt model had to encompass more than 4 patients. RESULTS Of 1872 articles, 16 met our criteria, involving 4304 patients, with 1619 undergoing VAS and 2685 receiving VPS placement. Analysis of revision surgeries showed no significant difference between VAS and VPS (risk ratio [RR] = 1.10, 95% CI: 0.9-1.34; I2 = 84%, random effects). Regarding infections, the analysis also found no significant difference between the groups (RR = 0.67, 95% CI: 0.36-1.25; I2 = 74%, random effects). There was no statistically significant disparity between both methods concerning shunt-related deaths (RR = 2.11, 95% CI: 0.68-6.60; I2 = 56%, random effects). Included studies after 2000 showed no VAS led to cardiopulmonary complications, and only 1 shunt-related death could be identified. CONCLUSION Both methods show no significant differences in procedure revisions, infections, and shunt-related mortality. The literature is outdated, research in adults is lacking, and future randomized studies are crucial to understand the profile of VAS when comparing it with VPS. The final decision on which distal site for cerebrospinal shunting to use should be based on the patient's characteristics and the surgeon's expertise.

Abstract
PURPOSE Cerebrospinal fluid (CSF) shunt failures in children are devastating. The primary aims of this study are to, firstly, review our institutional series of ventriculoperitoneal shunt (VPS) insertions and identify factors associated with shunt failure. METHODS This is a single-institution, retrospective study conducted over a 12-year period. All patients under 18 years old with VPS inserted were included. Variables of interest such as patient characteristics, hydrocephalus aetiology, shunt implant details, and outcomes were subjected to statistical analyses. RESULTS A total of 214 VPS patients were selected for this study. The mean age at VPS insertion was 6 months with a mean follow-up duration of 44 months. The most common type of hydrocephalus was obstructive (n = 142, 66.4%), and the most frequent aetiology was tumour-related (n = 66, 30.8%). The 30-day shunt failure rate was 9.3%: 9 infections (4.2%), 7 occlusions (3.3%), and 4 others (1.9%). After multivariable analysis, only recent central nervous system (CNS) infection prior to VPS insertion remained significant (OR 15.4 (1.3-175), p = 0.028). CONCLUSION This is the first, large-scale local study focused on the shunt failure in Singaporean children. Significant findings in our study demonstrate that recently treated CNS infection is a factor associated with 30-day shunt failure while the values of CSF constituents were not contributory.

Abstract
Optic pathway gliomas (OPGs) are benign tumors that can stop growing or even shrink. In recent years, surgical resection has not been considered the first-line treatment because of its high risk of complications. Chemotherapy is the mainstay of treatment for growing OPGs. Surgical treatment for OPGs with obstructive hydrocephalus is required. Ventriculoperitoneal shunting is effective for all types of hydrocephalus. However, long-term management is required, especially in pediatric cases, and there is a risk of shunt-related complications over a long lifespan. Debulking surgery for OPGs allows us to avoid shunt placement by creating a waterway and releasing the hydrocephalus. To reduce the surgical risk and invasiveness, we used an endoscopic canalization technique with a small-diameter cylinder. In this article, we present a case of endoscopic canalization of an obstructive hydrocephalus caused by OPGs in a 14-year-old female to illustrate our surgical technique.(Trial registration Registry name and number: Efficacy and safety of the neuro-endoscopic treatment for brain tumors (2019-0254)).

Abstract
A one-step modification of biomedical silicone tubing with N,N-dimethyltetradecylamine, C14, results in a composition designated WinGard-1 (WG-1, 1.1 wt % C14). A surface-active silicon-amine phase (SAP) is proposed to account for increased wettability and increased surface charge. To understand the mechanism of antimicrobial effectiveness, several procedures were employed to detect whether C14 leaching occurred. An immersion-growth (IG) test was developed that required knowing the bacterial Minimum Inhibitory Concentrations (MICs) and Minimum Biocidal Concentrations (MBCs). The C14 MIC and MBC for Gm- uropathogenic E. coli (UPEC), commonly associated with catheter-associated urinary tract infections (CAUTI), were 10 and 20 μg/mL, respectively. After prior immersion of WG-1 silicone segments in a growth medium from 1 to 28 d, the IG test for the medium showed normal growth for UPEC over 24 h, indicating that the concentration of C14 must be less than the MIC, 10 μg/mL. GC-MS and studies of the medium inside and outside a dialysis bag containing WG-1 silicone segments supported de minimis leaching. Consequently, a 5 log UPEC reduction (99.999% kill) in 24 h using the shake flask test (ASTM E2149) cannot be due to leaching and is ascribed to contact kill. Interestingly, although the MBC was greater than 100 μg/mL for Pseudomonas aeruginosa, WG-1 silicone affected an 80% reduction via a 24 h shake flask test. For other bacteria and Candida albicans, greater than 99.9% shake flask kill may be understood by proposing increased wettability and concentration of charge illustrated in the TOC. De minimis leaching places WG-1 silicone at an advantage over conventional anti-infectives that rely on leaching of an antibiotic or heavy metals such as silver. The facile process for preparation of WG-1 silicone combined with biocidal effectiveness comprises progress toward the goals of device designation from the FDA for WG-1 and clearance.

Abstract
BACKGROUND We aimed to characterize the caregiver experience in the detection and evaluation of pediatric cerebrospinal shunt malfunction. METHODS In this descriptive qualitative study, we recruited English-speaking caregivers of children aged five years or less in collaboration with a stakeholder organization. Semistructured interviews were completed; content targeted the caregiver experience of shunt malfunction. Interviews were audio-recorded, transcribed, and deidentified. Qualitative data were analyzed using a conventional content analysis approach. RESULTS We enrolled 20 caregivers (n = 20 mothers). The median child age at the time of the interview was 2.8 years; about half (n = 11) were born prematurely and the majority (n = 15) had shunts placed at age less than six months. Caregiver experiences of shunt malfunction were grouped into three major themes: (1) my error could be life or death: the high stakes of shunt malfunction and the ambiguity of malfunction symptoms exacerbated baseline caregiver vigilance; (2) finding and engaging people who can help: hurdles during malfunction evaluation included locating trusted clinicians and advocating for parental intuition; and (3) how the shunt defines our family: caregivers described evolving expertise and modifications made to everyday life due to the threat of malfunction. CONCLUSIONS In this study, caregivers highlighted the challenges associated with recognizing shunt malfunction, accessing necessary treatment, and the impact of their child's shunt on family life. Future work should leverage these findings to inform counseling about shunt malfunction, develop interventions to better support families in shunt malfunction identification, and educate medical providers.

Abstract
PURPOSE Pediatric hydrocephalus is a common and challenging condition. To date, the ventriculoperitoneal shunt (VPS) is still the main lifesaving treatment option. Nonetheless, it remains imperfect and is associated with multiple short- and long-term complications. This paper is a reflective review of the current state of the VPS, our knowledge gaps, and the future state of shunts in neurosurgical practice. METHODS AND RESULTS The authors' reflections are based on a review of shunts and shunt-related literature. CONCLUSION Overall, there is still an urgent need for the neurosurgical community to actively improve current strategies for shunt failures and shunt-related morbidity. The authors emphasize the role of collaborative efforts amongst like-minded clinicians to establish pragmatic approaches to avoid shunt complications.

Abstract
BACKGROUND Ventriculoatrial shunt (VAS) is considered the second option for treating hydrocephalus, but there remains a lack of robust evidence regarding its complications profile. PURPOSE Evaluate the complications associated with VAS. METHODS Adhering to PRISMA guidelines, the authors searched Embase, PubMed, and Web of Science databases to identify articles reporting on the complications of VAS. Eligible articles were required to report whether complications occurred in a cohort of at least four patients. The extraction process focused on various outcome measures, including overall complications, pulmonary complications, cardiac complications, mortality, shunt revisions, glomerulonephritis, intracranial hemorrhage, and hygroma. Complications were defined as any adverse events related to the procedure, including revisions. RESULTS After retrieving a total of 2828 articles, 53 studies met the predefined criteria, involving 2862 patients. The overall complication rate was estimated at 33 % (95 % CI: 25-42 %), while the long-term complications rate was found to be 49 % (95 % CI: 32-67 %). Among the pediatric population, the complication rate was calculated to be 53 % (95 % CI: 39-68 %). The overall revision rate was estimated at 32 % (95 % CI: 23-41 %), with an infection rate of 5 % (95 % CI: 3-7 %). Notably, in the pediatric group, the infection rate was 10 % (95 % CI: 6-13 %). The random analysis indicated an estimated risk of 0 % for glomerulonephritis, intracranial hemorrhage, hygroma, cardiac complications, pulmonary complications, and shunt-related mortality. CONCLUSION VAS is a safe alternative when ventriculoperitoneal shunting is not feasible. Risk of classic severe complications is minimal. Nevertheless, caution is required when shunting critical patients. Further randomized studies are warranted to establish the ideal shunt for different patients.

Abstract
OBJECTIVE The objective of this study was to determine the degree of progressive posthemorrhagic ventricular dilatation (PHVD) that is associated with a significant decrease in regional cerebral oxygen saturation (rScO2) in premature infants at risk for periventricular-intraventricular hemorrhage (PIVH). STUDY DESIGN Cranial ultrasound (US) and near-infrared spectroscopy (NIRS) measurements of rScO2 were performed on inborn infants with birth weights less than 1,250 g on admission and at 1, 4, and 8 weeks of age. Infants with severe PIVH were studied weekly. A 1-hour average of rScO2 was compared with the frontal-occipital horn ratio (FOHR) measured the same day. Generalized linear models were used to analyze the relationship between FOHR and rScO2, by severity of PIVH, and adjusted for gestational age. Cut-off points of 0.55 for FOHR and 45% for rScO2 were used to calculate odds ratios (OR) and 95% confidence intervals (CI). RESULTS The study cohort included 63 infants with normal US, 15 with grade-1 or -2 PIVH (mild group), and 21 with grade-3 or -4 PIVH (severe group). Increases in FOHR in the severe group were associated with decreases in rScO2 at 1 week (p = 0.036), 4 weeks (p = 0.013), and 8 weeks of life (p = 0.001) compared with the normal and mild groups. Infants with FOHR greater than 0.55 were 92% more likely to have rScO2 less than 45% when compared with infants with FOHR less than 0.55 (OR = 0.08, 95% CI: [0.04, 0.13], p < 0.001). CONCLUSION Progressive PHVD (FOHR > 0.55) is a strong predictor of compromised cerebral oxygenation. A combination of rScO2 and FOHR measurements may aid in identifying infants with PHVD that would benefit from early intervention. KEY POINTS · Earlier intervention in PHVD may improve outcomes.. · PHVD is diagnosed with US measurements of ventricular size.. · FOHR > 0.55 is associated with decreased cerebral perfusion..

Alternative Antimicrobial Irrigation Strategies for the Treatment of Infections in Children: A Review of the Existing Literature. Antibiotics (Basel) 2023; 12:1271. [PMID: 37627691 PMCID: PMC10451316 DOI: 10.3390/antibiotics12081271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 07/26/2023] [Accepted: 07/28/2023] [Indexed: 08/27/2023] Open
Abstract
As a synergistic treatment approach with systemic antimicrobial therapy or a systemic antibiotic-sparing strategy, the local administration of antimicrobial agents has been proposed as an alternative route for complicated infections. With the rationale of concentrating the active principle in the desired target site, avoiding potentially toxic systemic levels and bypassing anatomical and physiological barriers, local irrigation or infusion of antibiotics may effectively shorten the antimicrobial therapy course and reduce both infection-related and systemic therapy-related complications. Although evidence from the adult population supports its use in selected patients with an acceptable safety profile, data specifically focused on the pediatric population are limited. To provide a rapid and easily accessible tool for clinical practice, we synthesized the most relevant evidence on the use of local antimicrobial agents in common severe infections in children: meningitis, mediastinitis, pleural infections, recurrent urinary infections, and peritonitis. A literature search was performed using predefined combined keywords through an electronic research database (PubMed). Described molecules, dosages, routes, treated age groups, and related efficacy have been summarized for prompt application to clinical practice. It should, however, be noted that the evidence for the pediatric population remains limited, and the local administration of several molecules remains off-label. A careful multidisciplinary and patient-tailored evaluation, as well as a rational use of available guidelines, should always be the basis of clinical decision making in settings where local administration of antibiotics may be considered.

Abstract
Objective The aim of this study is to identify the factors predicting persistent hydrocephalus after periventricular tumor resection in children and assess the need and efficacy of perioperative cerebrospinal fluid (CSF) intervention. Methods We performed a retrospective analysis of pediatric patients who underwent resection surgery of a periventricular tumor between March 2012 and July 2021 at the Department of Neurosurgery in Zhujiang Hospital of South Medical University. Demographic, radiographic, perioperative, and dispositional data were analyzed using univariate and multivariate models. Results A total of 117 patients were enrolled in our study. Incidence of postoperative persistent hydrocephalus varied with tumor pathology (p = 0.041), tumor location (p = 0.046), surgical approach (p = 0.013), extension of resection (p = 0.043), tumor volume (p = 0.041), preoperative Evan's index (p = 0.002), and preoperative CSF diversion (p = 0.024). On logistic regression, posterior median approach (OR = 5.315), partial resection (OR = 20.984), volume > 90cm3 (OR = 5.768), and no preoperative CSF diversion (OR = 3.661) were independent predictors of postoperative persistent hydrocephalus. Preoperative Evan's index is significantly correlated with tumor volume (p = 0.019). Meanwhile, the need for preoperative CSF drainage in patients in this cohort was significantly correlated with tumor location (p = 0.019). Conclusion Tumor pathology, location, surgical approach, the extension of resection, tumor volume, preoperative Evan's index, and preoperative CSF diversion were considered to be predictive factors for postoperative persistent hydrocephalus. Notably, posterior median approach, partial resection, and tumor volume > 90cm3, without preoperative CSF diversion, were identified as independent risk factors for persistent postoperative hydrocephalus. Preoperative identification of children at risk of developing persistent postoperative hydrocephalus would avoid delays in planning the cerebrospinal fluid diversion. Active and effective preoperative hydrocephalus intervention in children with periventricular tumors is beneficial to reduce the incidence of persistent hydrocephalus and ventriculoperitoneal shunt surgery after resection.

Abstract
OBJECTIVE To characterize the microbiota of the cerebrospinal fluid (CSF) from children with hydrocephalus at the time of initial surgical intervention. STUDY DESIGN CSF was obtained at initial surgical intervention. One aliquot was stored in skim milk-tryptone-glucose-glycerol (STGG) medium and the second was unprocessed; both were then stored at -70°C. Bacterial growth for CSF samples stored in STGG were subsequently characterized using aerobic and anaerobic culture on blood agar and MALDI-TOF sequencing. All unprocessed CSF samples underwent 16S quantitative polymerase chain reaction (qPCR) sequencing, and a subset underwent standard clinical microbiological culture. CSF with culture growth (either after storage in STGG or standard clinical) were further analyzed using whole-genome amplification sequencing (WGAS). RESULTS 11/66 (17%) samples stored in STGG and 1/36 (3%) that underwent standard clinical microbiological culture demonstrated bacterial growth. Of the organisms present, 8 were common skin flora and 4 were potential pathogens; only 1 was also qPCR positive. WGAS findings and STGG culture findings were concordant for only 1 sample, identifying Staphylococcus epidermidis. No significant difference in time to second surgical intervention was observed between the STGG culture-positive and negative groups. CONCLUSION(S) Using high sensitivity methods, we detected the presence of bacteria in a subset of CSF samples at the time of first surgery. Therefore, the true presence of bacteria in CSF of children with hydrocephalus cannot be ruled out, though our findings may suggest these bacteria are contaminants or false positives of the detection methods. Regardless of origin, the detection of microbiota in the CSF of these children may not have any clinical significance.

Abstract
Ventriculoperitoneal (VP) shunts are a common neurosurgical procedure used to treat hydrocephalus. Despite their efficacy, many shunts fail and require revisions. The most common causes of shunt failure include obstruction, infection, migration, and perforation. Extraperitoneal migrations require urgent attention. We present a case of migration to the scrotum, a unique complication that may be present in young patients due to the presence of a patent processus vaginalis. Here, we discuss a case of a 16-month-old male patient with a VP shunt presenting with cerebrospinal fluid (CSF) drainage from his scrotum after an indirect hernia repair. This case represents an important reminder for physicians about the sequelae associated with VP shunt complications, particularly extraperitoneal migration, and brings awareness to the underlying factors that may increase this risk.

Pediatr Neurosurg 2023; 58:136-141. [PMID: 37231887 DOI: 10.1159/000530869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Accepted: 04/11/2023] [Indexed: 05/27/2023]
Abstract
INTRODUCTION Ventriculoperitoneal shunt (VPS) malfunction rates are as high as 40% in the first year with posthemorrhagic hydrocephalus (PHH) patients having the highest proximal occlusion risk. Debris, protein, and cellular ingrowth most commonly obstruct the proximal ventricular catheter and/or valve. Historically, no preventative methods have demonstrated efficacy. We present a technical note and case series describing the use of a retrograde proximal flushing device and prophylactic flushing protocol to maintain ventricular catheter patency and reduce proximal shunt occlusions. METHODS We present our 2.8-4-year follow-up data on the first 9 pediatric cases of ReFlow (Anuncia Inc, Scottsdale, AZ) device implantation combined with routine prophylactic flushing. Rationale for device implantation, patient selection, surgical procedure details, postoperative follow-up, and prophylactic flushing protocol are discussed as well as pre- and postimplantation ventricular catheter obstruction rates. We include a technical note on the device setup and prophylactic flushing protocol. RESULTS Patient average age was 5.6 years and all patients had PHH. Minimal follow-up was 2.8 years (range 2.8-4 years). Prophylactic flushing was initiated between 2 and 14 days after ReFlow implantation and has continued as of the last follow-up. In 7 patients, ReFlow implantation occurred during the revision of an existing shunt and in two, implantation was coincident with initial VPS placement. In the 2 years preceding ReFlow and prophylactic flushing, 14 proximal shunt failures occurred in the 7 patients with existing VPS. This was reduced to only one proximal shunt failure in all 9 patients during the full follow-up period after ReFlow and prophylactic flushing. CONCLUSION Pediatric VPS placement carries high rates of proximal catheter occlusion, often leading to emergency surgery, morbidity, or even death. The ReFlow device along with routine prophylactic flushing may reduce proximal obstruction and need for revision surgery. Higher patient numbers and longer follow-up periods are necessary to further elucidate the safety and effect of such a device on longer term shunt failures and revision surgery.

Abstract
PURPOSE The aim of this study is to analyze rates of ventriculopleural (VPL) shunt failure and complications among patients with pediatric hydrocephalus, and to analyze which factors may predict early (< 1 year) or late (> 1 year) VPL shunt failure in this sample. METHODS A retrospective chart review was conducted of all consecutive VPL shunt placements from 2000 to 2019 at our institution. Data was collected on patient characteristics, shunt history, and shunt type. Primary endpoints include rates of VPL shunt survival and rates of symptomatic pleural effusion. The Kaplan-Meier method was used to calculate shunt survival, and Fisher's exact test and t-test were used to compare differences between categorical variables and means, respectively (p < 0.05). RESULTS Thirty-one patients with pediatric hydrocephalus underwent VPL shunt placement (mean age 14.2 years). Of the 27 patients with long-term follow-up (mean 46 months), VPL shunt revision was required in 19, seven of which were due to pleural effusion. Overall shunt survival rates at 1, 3, 5, and 7 years were 76%, 62%, 55%, and 46%, respectively. Mean duration of shunt survival was 26.74 months. Overall pleural effusion rate was 26%. No patient-specific factors, including shunt valve type, were significantly associated with shunt survival, risk of early revision, or risk of pleural effusion. CONCLUSIONS Our results are comparable to those reported in the literature and represent one of the largest case series on the topic. VPL shunts are a viable second-line option when ventriculoperitoneal (VP) shunt placement is not possible or desirable, though there are high rates of shunt revision and pleural effusion.

Abstract
The purpose of this study was to outline the management of patients with appendicitis and ventriculoperitoneal shunt (VPS) in the largest pediatric surgery department in Germany. Patients with VPS presenting with an acute abdomen between 2012 and 2022 at a tertiary-care pediatric facility were the subject of a retrospective descriptive analysis. Patients were divided into two groups based on their diagnoses: group A (appendicitis) and group B (primary peritonitis). Medical records were analyzed to look at the diagnostics, operative approach, complications, peritoneal and liquor culture, and antibiotic treatment. A total of seventeen patients were examined: seven patients in group A and ten individuals in group B. In the present study patients in group A typically presented younger, sicker, and with more neurological symptoms than those in group B. All patients with appendicitis had their VPS exteriorized, and a new shunt system into the peritoneum was reimplanted 20 days later. Surgery should be aggressively administered to patients who present with an acute abdomen and a VPS. Change of the whole shunt system is suggested. Shunt infection and dysfunction should be ruled out in patients with abdominal symptoms, and surgical care should be started with a low threshold.

Abstract
Abstract
Background
Despite the high-frequency rate of cerebrospinal fluid shunt malfunction, radiological evaluation of CSF shunts has remained deficient, focusing mainly on demonstrating secondary signs of shunt failure rather than evaluating the shunt tube itself. We aimed to study the utility of different MR pulse sequences in evaluating the cranial and abdominal ends of CSF shunts in order to identify the potential cause of shunt failure and its impact on patient management.
Results
Twenty-five patients (18 males, 7 females, median age 2.5 years, IQR 0.75–15) were enrolled in the study, having 28 ventriculo-peritoneal shunts and single ventriculo-gallbladder shunt. The catheter lumen and fine intraventricular septae were only demonstrated in 3D-DRIVE sequences (p < 0.001). Except for three patients (having cranial end-related complications), all patients with cranial and/or abdominal end-related complications received surgery (p < 0.001, positive likelihood and negative likelihood ratios = 7.27, 0.3, respectively, sensitivity = 0.7 and specificity = 0.9). MRI findings (luminal occlusion, disconnection, CSF collection, or migration) were consistent with operative data. There is no significant difference between patients who underwent surgery and those with conservative management, or symptomatic and asymptomatic patients in terms of the prevalence of ventricular dilatation or white matter signal abnormality. The results of the abdomino-pelvic fat-suppressed T2-WI showed excellent agreement with ultrasound findings (Cohen’s Kappa 0.9). Quantitative PC could give insights into CSF dynamics, which depend on the site and cause of shunt malfunction.
Conclusions
MRI could be a one-stop destination for evaluating patients with suspected non-acute shunt malfunction. It was found to have clinical relevance in terms of accurately locating the exact site and possible cause of shunt-related complications.

Abstract
The use of invasive intracranial electroencephalogram (EEG) monitoring in the patient with a cerebrospinal fluid (CSF) diversionary shunt presents a conundrum -- the presence of a percutaneous electrode passing into the intracranial compartment presents a pathway for entry of pathogens to which a chronically implanted device like a shunt is especially susceptible to infection. In this case report, we describe the clinical and radiological features, medical and surgical management, and treatment outcomes of pediatric patients with shunted hydrocephalus who underwent invasive intracranial monitoring over an eight-year period. Three cases of children undergoing invasive intracranial monitoring were included in this study. Invasive monitoring for each patient occurred over three to six days. In each case, invasive intracranial monitoring was completed successfully, without resulting infection or shunt malfunction. While the second procedure was complicated by the formation of a pneumocephalus, there was no associated midline shift, and invasive intracranial monitoring was completed without incidence. Each patient received further surgery that successfully reduced seizure frequency. This study suggests that, while children with CSF diversionary shunts are at an inherently increased risk for infection and other complications, invasive intracranial monitoring is a relatively safe and feasible option in these patients. Future studies should explore the optimal duration for intracranial monitoring in pediatric patients with chronically implanted devices.

Abstract
OBJECTIVE Ventriculoperitoneal shunt (VPS) surgery is a common treatment for hydrocephalus in children and adults, making it one of the most common procedures in neurosurgery. Children being treated with a VPS often require several revisions during their lifetime with a lifetime revision rate of up to 80%. Several different techniques exist for inserting the distal catheter, while mini-laparotomy, trocar, or laparoscopy is traditionally used. As opposed to adults, only few studies exist, comparing the outcome of the different distal catheter placement techniques in children. This international survey aims to investigate the current daily practice concerning distal shunt placement techniques in children. MATERIAL AND METHODS An online questionnaire investigating the different techniques used to place the distal catheter in pediatric VPS surgery was distributed internationally. All results were analyzed using descriptive and comparative statistics. RESULTS A total of 139 responses were obtained. Mini-laparotomy was reported to be the most frequently used technique (n = 104, 74.8%) for distal shunt placement in children, while laparoscopic or trocar-assisted placements were only used by 3.6% (n = 5) and 21.6% (n = 30) of all respondents, respectively. Over half (n = 75, 54.0%) of all respondents do not believe that laparoscopic placement improves the outcome. CONCLUSION This international survey shows that mini-laparotomy is the most frequently used technique for distal VPS placement in children all over the world. Further randomized trials are needed to elucidate this matter.

Abstract
Congenital hydrocephalus (CH) is a common neurological disorder affecting many newborns. Imbalanced neurogenesis is a major cause of CH. Multiple CH-associated mutations are within the RNA-binding domain of Trim71, a conserved, stem cell-specific RNA-binding protein. How these mutations alter stem cell fate is unclear. Here, we show that the CH-associated mutations R595H and R783H in Trim71 accelerate differentiation and enhance neural lineage commitment in mouse embryonic stem cells (mESCs), and reduce binding to mRNAs targeted by wild-type Trim71, consistent with previous reports. Unexpectedly, however, each mutant binds an ectopic and distinct repertoire of target mRNAs. R595H-Trim71, but not R783H-Trim71 nor wild-type Trim71, binds the mRNA encoding β-catenin and represses its translation. Increasing β-catenin by overexpression or treatment with a Wnt agonist specifically restores differentiation of R595H-Trim71 mESCs. These results suggest that Trim71 mutations give rise to unique gain-of-function pathological mechanisms in CH. Further, our studies suggest that disruption of the Wnt/β-catenin signaling pathway can be used to stratify disease etiology and develop precision medicine approaches for CH.

Abstract
BACKGROUND Social risk factors have been shown to negatively affect health outcomes in children. However, this has not been characterized regarding pediatric shunted hydrocephalus. OBJECTIVE To explore the impact of social risk factors on outcomes in pediatric shunted hydrocephalus with the goal of identifying specific areas of intervention that might improve the outcomes of children undergoing cerebrospinal fluid (CSF) diversion. METHODS In an all-payer administrative database, records between January 2010 and October 2020 were analyzed to identify children undergoing CSF shunting procedures. Children with social risk factors were compared with those without regarding rates of infection, shunt-related interventions, and mortality within 5 years of their shunting procedure. RESULTS Among the 5420 children who underwent first-time shunting procedures, 263 (4.9%) were identified to have social risk factors. Children with identified social risk factors had increased odds of central nervous system infection (odds ratio [OR] 2.06, 95% CI 1.45-2.91), revision (OR 2.43, 95% I 1.89-3.12), and mortality (OR 2.86, 95% CI 1.23-5.72). The mean numbers of computed tomography studies (14.60 ± 17.78 vs 6.34 ± 6.10), MRI studies (18.76 ± 24.37 vs 7.88 ± 24.37), and shunt series X-rays (17.22 ± 19.04 vs 7.66 ± 8.54) were increased among children with social risk factors. CONCLUSION Children with social risk factors had increased rates of central nervous system infection, shunt-related interventions, and mortality within 5 years of CSF shunting. We underscore the importance of characterizing the impact of social risk factors in specific conditions, such as pediatric shunted hydrocephalus, and look to future directions aimed to mitigate these risk factors with coordination and direction of individualized resources, encouragement of advocacy, and community partnership.

Abstract
Objective: This study aimed to describe shunt malfunction symptoms in children ≤5 years old. Results: In a national survey of 228 caregivers, vomiting (23.1%), irritability (20.8%), and sleepiness (17.2%) were the most frequent symptoms of malfunction. These symptoms also occurred in over 1/3 of "false alarms" experienced by 75% of respondents. Compared with malfunctions, irritability (OR = 1.39, 95% CI [1.05, 1.85], p = 0.022) and fever (OR = 2.22, 95% CI [1.44, 3.44], p < 0.001) were more likely false alarms. Caregivers counseled about "most" symptoms were more confident detecting malfunctions than those informed of "some" (p = 0.036). The majority of caregivers (85%) first contacted a neurosurgeon with concerns about malfunction, followed by neurologists (22%) and family/friends (19%). Most (85%) struggled to differentiate malfunction from regular development. Conclusions: Vomiting, irritability, and sleepiness were the most common symptoms of shunt malfunction and false alarms for children ≤5 years. Most caregivers reported challenges differentiating malfunctions from their child's development.

Abstract
The leading cause of ventricular shunt failure in pediatric patients is proximal catheter occlusion. Here, we evaluate various types of shunt catheters to assess in vitro cellular adhesion and obstruction. The following four types of catheters were tested: (1) antibiotic- and barium-impregnated, (2) polyvinylpyrrolidone, (3) barium stripe, and (4) barium impregnated. Catheters were either seeded superficially with astrocyte cells to test cellular adhesion or inoculated with cultured astrocytes into the catheters to test catheter performance under obstruction conditions. Ventricular catheters were placed into a three-dimensional printed phantom ventricular replicating system through which artificial CSF was pumped. Differential pressure sensors were used to measure catheter performance. Polyvinylpyrrolidone catheters had the lowest median cell attachment compared to antibiotic-impregnated (18 cells), barium stripe (17 cells), and barium-impregnated (21.5 cells) catheters after culture (p < 0.01). In addition, polyvinylpyrrolidone catheters had significantly higher flow in the phantom ventricular system (0.12 mL/min) compared to the antibiotic coated (0.10 mL/min), barium stripe (0.02 mL/min) and barium-impregnated (0.08 mL/min; p < 0.01) catheters. Polyvinylpyrrolidone catheters showed less cellular adhesion and were least likely to be occluded by astrocyte cells. Our findings can help suggest patient-appropriate proximal ventricular catheters for clinical use.

Revision rates of flow- versus pressure-regulated ventricular shunt valves for the treatment of hydrocephalus in neonates following germinal matrix haemorrhage-a retrospective review. Childs Nerv Syst 2022; 39:943-952.

Abstract
PURPOSE Neonates with ventricular shunts inserted for hydrocephalus following germinal matrix haemorrhage (GMH) have high rates of shunt revision. The shunt valve plays a key role in regulating the function of the shunt. In this study, we aim to determine if the choice of flow-regulated or pressure-regulated valve used in the initial implantation of a shunt affects the rate of shunt revision. METHODS A retrospective cohort comparison study was performed on 34 neonates with hydrocephalus following GMH who underwent placement of a ventricular shunt at the Queensland Children's Hospital from November 2014 to June 2020. The primary outcome examined was the need for revision or replacement of the ventricular shunt after successful initial placement within 2 years of implantation. The secondary outcome examined was the survival time of the shunt. RESULTS 16 patients had placement of a flow-regulated valve, and 18 patients had placement of a pressure-regulated valve. 14 (87.5%) patients with flow-regulated valves required replacement during the follow-up period. 2 (18.18%) patients with a fixed pressure regulated underwent revision, while 2 (28.57%) programmable pressure-regulated shunts required revision. Patients that had a flow-regulated valve had a statistically significant higher rate of revision compared to those who had a pressure-regulated valve, (87.5% flow vs 22.22% pressure) with a P-value of < 0.001. Valve obstruction was also more common in patients with flow-regulated valves than pressure-regulated valves (4 vs 0) with a P-value of 0.010. Overall mean median survival time was 22.06 months, shunts with flow-regulated valves had a shorter median survival time of 3.19 months compared with over 24 months for pressure-regulated valves with a P-value of < 0.001. CONCLUSION Our study suggests that the initial implantation of flow-regulated valves may carry an increased total rate of shunt revision and valve obstruction within the first 2 years following implantation compared to pressure-regulated valves in patients with hydrocephalus following GMH.

Abstract
BACKGROUNDS Dandy-Walker syndrome (DWS) is a group of brain malformations which occasionally accompanied by psychotic symptoms. The co-occurrence of DWS and epilepsy in children is quite rare. CASE DESCRIPTION We reported a 14-year-old male who presented with a 8-month history of inconsistent upper limb tremor and accidental seizure. The MRI showed the typical alterations of DWS: cystic dilatation of the fourth ventricle, vermian hypoplasia, enlarged posterior fossa. He received the ventriculoperitoneal shunting (VPS) placement for hydrocephalus and had a symptom-free period for 8 days. Then he experienced a recurrence of involuntary upper limb tremor and behavior disturbance after decreasing the pressure of cerebrospinal fluid (CSF) from 150 to 130 mm Hg. After being treated with Olanzapine 10 mg/d, Clonazepam 3 mg/qn and Valproate acid (VPA) 500 mg/bid for nearly a month, his mental status and psychotic symptoms fluctuated. A search of Pub Med showed little report of hydrocephalus and DWS comorbidity with seizure and psychosis. Here we presented the whole process of a rare disease from the very beginning with all his symptoms, examinations and treatments. CONCLUSION VPS placement surgery at an earlier stage may be an effective way to avoid inevitable brain damage so as to improve the clinical outcomes for patients with DWS. Continued treatment with regard to DWS condition may include shunt placement, but it mainly focus on developmental concerns, with occupational and physical therapy along with ongoing supportive psychotherapy to improve the coping skills and quality of life.

CHILDREN (BASEL, SWITZERLAND) 2022; 9:1453.

Abstract
OBJECTIVE One of the major causes of cerebral ventricular shunt failure is proximal catheter occlusion. We describe a novel ventricular cerebrospinal fluid (CSF) flow replicating system that assesses pressure and flow responses to varying degrees of catheter occlusion. METHODS Ventricular catheter performance was assessed during conditions of partial and complete occlusion. The catheters were placed into a three-dimensionally-printed phantom ventricular replicating system. Artificial CSF was pumped through the ventricular system at a constant rate of 1 mL/min to mimic CSF flow, with the proximal end of the catheter in the phantom ventricle. Pressure transducer and flow rate sensors were used to measure intra-phantom pressure, outflow pressure, and CSF flow rates. The catheters were also inserted into silicone tubing and pressure was measured in the same manner for comparison with the phantom. RESULTS Pressure measured in the ventricle phantom did not change when the outflow of the ventricular catheter was partially occluded. However, the intraventricular phantom pressure significantly increased when the outflow catheter was 100% occluded. The flow through the catheter showed no significant difference in rate with any degree of partial occlusion of the catheter. At the distal end of the partially occluded catheters, there was less pressure compared with the nonoccluded catheters. This difference in pressure in partially occluded catheters correlated with the percentage of catheter hole occlusion. CONCLUSIONS Our model mimics the physiological dynamics of the CSF flow in partially and completely obstructed ventricular catheters. We found that partial occlusion of the catheter had no effect on the CSF flow rate, but did reduce outflow pressure from the catheter.

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
Infection of a cerebrospinal fluid system is a serious medical complication. We performed a retrospective monocentric analysis on temporary and permanent cerebrospinal fluid devices in children with and without cancer, covering a period of over 14 years. Between 2004 and 2017, 275 children with a cerebrospinal fluid system were seen at our institution. Thirty-eight children suffered from 51 microbiologically proven infectious episodes of the cerebrospinal fluid system (12 children with cancer and 26 children without cancer). Independently of the cerebrospinal fluid system used, the incidence of infection did not significantly differ between children with and without cancer and was the highest in children younger than one year. Infection occurred earlier in external ventricular drain (EVD) than ventriculoperitoneal (VP) shunt, and in EVD significantly earlier in children with cancer compared with patients without cancer. The pathogens isolated were mainly Gram-positive bacteria, in particular Staphylococcus spp., which should be taken into account for empirical antimicrobial therapy.

Abstract
BACKGROUND AND IMPORTANCE Abdominal pseudocyst (APC) is an uncommon but well-recognised complication of ventriculo-peritoneal (VP) shunt. Diagnosis is based on clinical features of shunt malfunction, including headaches, vomiting and drowsiness, and abdominal swelling. APCs can grow to large sizes resulting in compression of abdominal viscera; however, inferior vena cava (IVC) compression is extremely rare, and only one other case associated with VP shunt had been reported. CLINICAL PRESENTATION We report a case of a 12-year-old girl with a background of open myelomeningocoele repair, kyphoscoliosis and right-sided VP shunt in situ who presented with bilateral lower limb swelling and abdominal distension. She exhibited no features of raised intracranial pressure but had bilateral pitting oedema up to the groin. Abdominal ultrasound and CT scan showed a massive septated pseudocyst (20 × 18 × 8 cm) compressing the IVC. The APC was drained, and the shunt was externalised, with conversion to a ventriculo-atrial (VA) shunt 1 week later after cultures of the cystic fluid, cerebrospinal fluid and shunt tube came back sterile. The patient remained well with no recurrence of the abdominal fluid and no VA shunt complication at 36-month follow-up. CONCLUSION This patient had specific risk factors for development of a massive APC and the subsequent IVC compression, including prior surgeries, spinal deformity, abnormal abdominal anatomy and poor abdominal muscle tone and sensation. Early recognition of this complication and prompt alleviation of the mass effect of IVC compression can prevent long-term neurological and vascular sequalae.

Abstract
Fourteen months after the implantation of a ventriculoperitoneal shunt catheter, a six-year-old boy developed recurrent, severe headaches and vomiting every three weeks. The attacks were of such severity that hospitalizations for analgesic and antiemetic therapies and intravenous rehydration and electrolyte substitution were repeatedly required. The patient was asymptomatic between the attacks. After an extensive diagnostic workup-including repeated magnetic resonance imaging (MRI) and neurosurgical examinations-common differential diagnoses, including shunt overdrainage, were ruled out. The patient was transferred to a specialized pediatric pain clinic with suspected cyclic vomiting syndrome (CVS). Despite intensive and in part experimental prophylactic and abortive pharmacological treatment, there was no improvement in his symptoms. Consecutive MRI studies reinvestigating the initially excluded shunt overdrainage indicated an overdrainage syndrome. Subsequently, the symptoms disappeared after disconnecting the shunt catheter. This case report shows that even if a patient meets CVS case definitions, other differential diagnoses must be carefully reconsidered to avoid fixation error.

The utility of congenital cardiac status to predict endoscopic third ventriculostomy and ventriculoperitoneal shunt failure in hydrocephalic infants. J Neurosurg Pediatr 2022; 29:528-535.

Abstract
OBJECTIVE The effect of congenital cardiac status on endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS) failure in hydrocephalic infants is unknown. Because cardiac status in infants can impact central venous pressure (CVP), it is possible that congenital heart disease (CHD) and congenital cardiac anomalies may render these cerebrospinal fluid diversion interventions more susceptible to failure. Correspondingly, the aim of this study was to determine how CHD and congenital cardiac anomalies may impact the failure of these initial interventions. METHODS A retrospective review of the Nationwide Inpatient Sample (NIS) database was conducted. Infants (aged < 1 year) with known congenital cardiac status managed with either ETV or VPS were included. Quantitative data were compared using either parametric or nonparametric methods, and failure rates were modeled using univariable and multivariable regression analyses. RESULTS A total of 18,763 infants treated with ETV or VPS for hydrocephalus were identified in our search, with ETV used to treat 7657 (41%) patients and VPS used to treat 11,106 (59%). There were 6722 (36%) patients who presented with CHD at admission, and a total of 25 unique congenital cardiac anomalies were detected across the cohort. Overall, the most common anomaly was patent ductus arteriosus (PDA) in 4990 (27%) patients, followed by atrial septal defect (ASD) in 2437 (13%) patients and pulmonary hypertension in 810 (4%) patients. With respect to initial intervention failure, 3869 (21%) patients required repeat surgical intervention during admission. This was significantly more common in the ETV group than the VPS group (36% vs 10%, p < 0.01). In both the ETV and VPS groups, CHD (p < 0.01), including all congenital cardiac anomalies, was an independent and significant predictor of failure. ASD (p < 0.01) and PDA (p < 0.01) both significantly predicted ETV failure, and PDA (p < 0.01) and pulmonary hypertension (p = 0.02) both significantly predicted VPS failure. CONCLUSIONS These results indicate that congenital cardiac status predicts ETV and VPS failure in patients with infantile hydrocephalus. The authors hypothesized that this finding was primarily due to changes in CVP; however, this may not be completely universal across both interventions and all congenital cardiac anomalies. Future studies about optimization of congenital cardiac status with ETV and VPS are required to understand the practical significance of these findings.

Abstract
Hydrocephalus is the most common neurosurgical disorder in children, and cerebrospinal fluid (CSF) diversion with shunt placement is the most commonly performed pediatric neurosurgical procedure. CT is frequently used to evaluate children with suspected CSF shunt malfunction to assess change in ventricular size. Moreover, careful review of the CT images is important to confirm the integrity of the imaged portions of the shunt system. Subtle shunt disruptions can be missed on multiplanar two-dimensional (2-D) CT images, especially when the disruption lies in the plane of imaging. The use of volume-rendered CT images enables radiologists to view the extracranial shunt tubing within the field of view as a three-dimensional (3-D) object. This allows for a rapid and intuitive method of assessing the integrity of the extracranial shunt tubing. The purpose of this pictorial essay is to discuss how volume-rendered CT images can be generated to evaluate CSF shunts in the pediatric population and to provide several examples of their utility in diagnosing shunt disruption. We also address the potential pitfalls of this technique and ways to avoid them.

Abstract
This case report provides an account of transcutaneous ventriculo-peritoneal (VP) shunt extrusion with silent bowel perforation occurring 2 years post digestive surgery. A 22-year-old man treated since childhood for post-infectious hydrocephalus was referred to our neurosurgery department for an inflammatory wound to the right hypochondrium caused by an abandoned calcified VP shunt. This VP shunt was surgically removed without complications. The perforated bowel required no direct repair. Progress is favorable at 1 year follow-up.

Abstract
A 14-year-old boy with a history of shunted congenital hydrocephalus began having headaches with nausea and vomiting after transcontinental flights. He gradually developed horizontal diplopia indicative of mild bilateral sixth nerve palsy, without papilledema or ventriculomegaly. Intracranial pressure monitoring showed no signs of elevation. After he subsequently developed papilledema, surgical exploration showed shunt malfunction, and shunt replacement produced rapid resolution of symptoms. This case demonstrates the importance of relying on clinical history and neuro-ophthalmologic examination in patients with hydrocephalus and suspected shunt failure, even when objective confirmatory evidence of intracranial pressure elevation is lacking.

Abstract
BACKGROUND: Shunt infection is one of the dreaded and serious complications following ventriculoperitoneal shunt (VP shunt) insertion, especially in a pediatric population. Numerous risk factors have been identified, particularly in developing countries, indicating that age may play an essential element in the pathogenesis of shunt infection, typically in patients <1-year-old. However, a few research demonstrate the inverse result.
AIM: The purpose of this was to determine the relationship between age and shunt infection so that it can be taken into consideration when performing VP shunt insertion.
METHODS: From January 2017 to December 2019, 98 pediatric patients with hydrocephalus who underwent VP shunt insertion were retrospectively reviewed to determine the relationship between age and shunt infection. We evaluated the microbiology results and management of shunt infection in patients with shunt infection.
RESULTS: Fifteen (15.15%) of 98 patients developed shunt infection. Patients aged >3–6 months had a significantly increased risk of shunt infection (p = 0.04; RR = 4.15; CI 95% = 1.19–14.45). Staphylococcus aureus was the most frequently encountered pathogen in pediatric patients with shunt infection (53.3%), and the most common management for shunt infection was complete removal of the shunt and systemic antibiotics followed by re-insertion of the shunt after the cerebrospinal fluid was sterile (46.6%).
CONCLUSION: We conclude that age, especially those aged >3–6 months, has a significantly higher risk of shunt infection in pediatric patients.

Abstract
Multiple alternative sites for distal ventriculoperitoneal shunts have been described including pleural, atrial, ureteral, fallopian, and gallbladder placement. In medically complex patients the sites for cerebrospinal fluid (CSF) diversion can be exhausted. We present a case where open retroperitoneal inferior vena cava cannulation was used for successful atrial catheter placement in a 17-month-old female. The patient had a complex abdominal, pulmonary, and vascular history precluding placement of the distal catheter in other sites or atrial placement through more peripheral venous cannulation. The patient underwent uncomplicated open retroperitoneal exposure of her inferior vena cava (IVC) with cannulation and placement of atrial catheter under fluoroscopic guidance. At the follow-up one year after surgery, the patient did not require revision with appropriate placement of the distal atrial catheter.

Abstract
Severe meningitis, especially basilar meningitis, can lead to hydrocephalus requiring external ventricular drain (EVD) placement. There are differences in cerebrospinal fluid (CSF) obtained from an EVD compared to a lumbar puncture (LP). Hence, it becomes difficult to compare LP and EVD samples for diagnosis and monitoring of meningitis. Recognizing these differences is important to properly treat and discontinue antibiotics. We report a case series of 6 patients with meningitis comparing EVD and LP CSF study analysis. In all 6 patients, CSF from LP was obtained before EVD placement by 1.7 days on average. Although corrected white blood cell (WBC) counts were elevated in CSF obtained from LP and EVD, the counts were significantly higher in LP CSF. Protein concentration in LP CSF was also significantly higher than EVD CSF. Glucose and red blood cells varied in both LP and EVD samples. Even though EVD CSF was obtained later in the clinical course than LP, slower circulation of CSF in lumbar space as compared to ventricles is likely the reason for a more sterile appearance of EVD CSF for the diagnosis of meningitis. It is important to recognize these differences as EVD CSF analysis for diagnosis of meningitis may lead to a missed diagnosis and false perception of significant improvement when monitoring response to treatment. One can consider repeating LP prior to discontinuation of antibiotics to properly determine the extent of improvement given EVD CSF sample appears more sterile in comparison. Larger studies are needed to confirm the above findings.

Abstract
BACKGROUND AND AIM Shunt dysfunction is a common event, especially in children who have this intervention performed early in life. The consequences of chronic shunt overdrainage can be multiple since the cerebral hydrodynamics is altered. A thrombotic event with consequent symptoms of intracranial hypertension is discussed in this article. MATERIAL AND METHODS We performed a detailed review of cerebral hydrodynamics and intracranial pressure compensation mechanisms and how this can alter cerebral venous circulation. Next, we report the case of a 4-year-old child with such a clinical presentation that was conducted by our team. RESULTS A child with a history of hydrocephalus treated with a ventriculo-peritoneal (VP) shunt in his early childhood presented with symptoms of intracranial hypertension, initial computed tomography (CT) demonstrating reduced-sized ventricles. Complementary investigation showed bilateral papilledema, cranial suture closure, changes compatible with Chiari type I, and venous sinus thrombosis (transverse and sigmoid, bilaterally). The case was managed conservatively with full anticoagulation with enoxaparin. Four months after the onset of symptoms, there was an improvement in the clinical and imaging status. CONCLUSION A condition of severe headache in a patient with an apparently functioning shunt and small ventricles on initial CT should open up a range of diagnostic possibilities, with pseudotumor cerebri syndrome and cerebral venous sinus thrombosis being suggested. The therapeutic approach in these cases must be individualized.
