[PMID: 36960505 PMCID: PMC10209765 DOI: 10.4103/ajps.ajps_68_21] [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: 05/01/2021] [Revised: 06/09/2022] [Accepted: 06/22/2022] [Indexed: 01/06/2023] Open
Abstract
Objectives The primary objective of this study was to analyse the demographics of the children who presented with ventriculoperitoneal shunt (VPS) complications. The secondary objectives were to review the clinical characteristics, surgical procedures performed for the management of VPS complications and the final outcome. Materials and Methods This is a single-institution observational study that included children below 12 years of age who required VPS revisions during the study period. Results During the study period of 10 years, n = 336 VPS catheters were implanted for the treatment of hydrocephalus in children. Forty (11.90%) children developed various VPS complications and required VPS revisions in the follow-up period. A total of n = 30 (8.92%) children (n = 21 boys and n = 9 girls) were selected/recruited for the present study, and they required n = 34 revision procedures. The mean interval from VPS insertion to the diagnosis of the complication was 7.29 months. VPS complications that required revisions occurred in the following order of frequency: (1) VPS catheter, cerebrospinal fluid (CSF) or shunt tract infection n = 8 (2.38%); (2) malfunction of distal VPS catheter n = 7 (2.08%); (3) coiling of distal VPS catheter at abdominal area n = 6 (1.78%); (4) extrusion of VPS catheter n = 5 (1.48%); (5) CSF leak from abdominal wound site/umbilicus n = 4 (1.19%); (6) malfunction of ventricular catheter n = 3 (0.89%) and (7) CSF pseudocyst peritoneal cavity n = 1 (0.29%). Surgical procedures were performed for the treatment of abovementioned complications in the following order of frequency: (1) revision of distal VPS catheter n = 14 (4.16%), (2) removal of entire VPS catheter ± external ventricular drainage (EVD) n = 7 (2.08%), (3) distal VPS catheter converted as EVD n = 6 (1.78%), (4) revision of proximal VPS catheter n = 3 (0.89%), (5) revision of entire VPS catheter n = 3 (0.89%) and (6) CSF pseudocyst excision n = 1 (0.29%). This study also documented n = 2 (6.6%) deaths during the post-operative period. Conclusion VPS insertion done for the treatment of hydrocephalus in infants and children was associated with various complications. Seventy per cent of the complications occurred within the first 6 months after the VPS insertion. Two-thirds of the complications were related to the distal VPS catheter.

Abstract
Background Hydrocephalus is a common problem in neurosurgery with shunt placement remains the mainstay of the management. However, shunt placement generally requires following surgical procedures, including shunt revision. Despite the recent developments, the incidence of shunt failure remains high, approximately 30-51% in the 1st year following the shunt placement. Methods An observational retrospective study of pediatric neurosurgery patients whom underwent CSF shunting procedure, both primary and repeated VPS, VAS, CPS, and subdural-peritoneal shunt procedures between January 2018 and May 2019. The patients were observed for 12 months for potential complication requiring shunt revision following the shunt placement. Results A total of 142 patients underwent shunt placement. The shunt revision within 12 months was found in 26 patients (18.3%), 25 cases were VPS (96.2%) and one case was CPS (3.8%). The mean period of time between shunt placement to shunt revision was 3.96 months. Age of under 6 months old during the shunt placement showed significantly higher risk for shunt revision (RR 2.32 CI 1.13-4.74, P = 0.018). The most common diagnosis requiring shunt revision was congenital anomaly (16 cases, 61.5%). The most common cause of revision was shunt malfunction, with 21 cases (80.8%) followed by infected shunt with 5 cases (19.2%). Conclusion The 1st year observation showed relatively high rate for shunt revision. The patient underwent shunt procedure should be regularly followed up in long period for better evaluation of the outcome. The application of shunt registry in some countries appears to be efficient and beneficial for sustainable follow-up in patients underwent shunt placement.

Abstract
BACKGROUND Hydrocephalus is managed by surgically implanting flow-diversion technologies such as differential pressure valves and antisiphoning devices; however, such hardware is prone to failure. Extensive research has tested them in flow-controlled settings using saline or de-aerated water, yet little has been done to validate their performance in a setting recreating physiologically relevant parameters, including intracranial pressures, cerebrospinal fluid (CSF) protein content, and body position. OBJECTIVE To more accurately chart the episodic drainage characteristics of flow-diversion technology. A gravity-driven benchtop model of flow was designed and tested continuously during weeks-long trials. METHODS Using a hydrostatic pressure gradient as the sole driving force, interval flow rates of 6 valves were examined in parallel with various fluids. Daily trials in the upright and supine positions were run with fluid output collected from distal catheters placed at alternating heights for extended intervals. RESULTS Significant variability in flow rates was observed, both within specific individual valves across different trials and among multiple valves of the same type. These intervalve and intravalve variabilities were greatest during supine trials and with increased protein. None of the valves showed evidence of overt obstruction during 30 d of exposure to CSF containing 5 g/L protein. CONCLUSION Day-to-day variability of ball-in-cone differential pressure shunt valves may increase overdrainage risk. Narrow-lumen high-resistance flow control devices as tested here under similar conditions appear to achieve more consistent flow rates, suggesting their use may be advantageous, and did not demonstrate any blockage or trend of decreasing flow over the 3 wk of chronic use.

Abstract
PURPOSE This retrospective cohort study aimed to investigate the surgical and neurodevelopmental outcomes (NDO) of infant hydrocephalus. We also sought to determine whether these outcomes are disproportionately poorer in post-haemorrhagic hydrocephalus (PHH) compared to other causes of infant hydrocephalus. METHODS A review of all infants with hydrocephalus who had ventriculoperitoneal (VP) shunts inserted at Great Ormond Street Hospital (GOSH) from 2008 to 2018 was performed. Demographic, surgical, neurodevelopmental, and other clinical data extracted from electronic patient notes were analysed by aetiology. Shunt survival, NDO, cerebral palsy (CP), epilepsy, speech delay, education, behavioural disorders, endocrine dysfunction, and mortality were evaluated. RESULTS A total of 323 infants with median gestational age of 37.0 (23.29-42.14) weeks and birthweight of 2640 g (525-4684 g) were evaluated. PHH was the most common aetiology (31.9%) and was associated with significantly higher 5-year shunt revision rates, revisions beyond a year, and median number of revisions than congenital or "other" hydrocephalus (all p < 0.02). Cox regression demonstrated poorest shunt survival in PHH, related to gestational age at birth and corrected age at shunt insertion. PHH also had the highest rate of severe disabilities, increasing with age to 65.0% at 10 years, as well as the highest CP rate; only genetic hydrocephalus had significantly higher endocrine dysfunction (p = 0.01) and mortality rates (p = 0.04). CONCLUSIONS Infants with PHH have poorer surgical and NDO compared to all other aetiologies, except genetic hydrocephalus. Research into measures of reducing neurodisability following PHH is urgently required. Long-term follow-up is essential to optimise support and outcomes.

Abstract
ABSTRACT
BACKGROUND
The Congress of Neurological Surgeons reviews its guidelines according to the Institute of Medicine's recommended best practice of reviewing guidelines every 5 yrs. The authors performed a planned 5-yr review of the medical literature used to develop the “Pediatric hydrocephalus: systematic literature review and evidence-based guidelines” and determined the need for an update to the original guideline based on new available evidence.
OBJECTIVE
To perform an update to include the current medical literature for the “Pediatric hydrocephalus: systematic literature review and evidence-based guidelines”, originally published in 2014.
METHODS
The Guidelines Task Force used the search terms and strategies consistent with the original guidelines to search PubMed and Cochrane Central for relevant literature published between March 2012 and November 2019. The same inclusion/exclusion criteria were also used to screen abstracts and to perform the full-text review. Full text articles were then reviewed and when appropriate, included as evidence and recommendations were added or changed accordingly.
RESULTS
A total of 41 studies yielded by the updated search met inclusion criteria and were included in this update.
CONCLUSION
New literature resulting from the update yielded a new recommendation in Part 2, which states that neuro-endoscopic lavage is a feasible and safe option for the removal of intraventricular clots and may lower the rate of shunt placement (Level III). Additionally a recommendation in part 7 of the guideline now states that antibiotic-impregnated shunt tubing reduces the risk of shunt infection compared with conventional silicone hardware and should be used for children who require placement of a shunt (Level I). <https://www.cns.org/guidelines/browse-guidelines-detail/pediatric-hydrocephalus-guideline>

Abstract
Objective: Ventriculoperitoneal (VP) shunt surgery is one of the commonly performed neurosurgical procedures. Complications due to shunt failure are associated with high morbidity and mortality. We report an analysis of risk factors for shunt failure in pediatric patients from a single institution in Nepal. Materials and Methods: A retrospective analytical study with prospective data was designed. All children younger than 15 years, with first time VP shunting, at a tertiary government hospital in Kathmandu during 2014-2017 were followed up. Association of independent variables with the primary outcome variable (complication of VP shunt) was analyzed using Chi-square test. Bivariate logistic regression was performed to identify unadjusted odds ratio (OR) with 95% confidence interval (CI). Multivariate logistic regression model was designed to calculate adjusted OR with 95% CI. Results: Of 120 patients, more than half (55.8%) of the patients were male. Mean age was 62.97 months. Maximum duration of follow-up was 30 months. Most common cause of hydrocephalus was congenital aqueductal stenosis (40.8%) followed by tumors (29.2%). Overall shunt complication was found in 26.7% (95% CI 19.0%–35.5%). Shunt infection was seen in 5% while malfunction without infection was found in 21.7%. Bivariate logistic regression showed duration of surgery more than 1 h (OR 2.67, 95% CI 1.11–6.42, P = 0.028) compared to 1 h or less, experienced surgeon (OR 0.37, 95% CI 0.16–0.89, P = 0.026) compared to residents, and emergency surgery (OR 3.97, 95% CI 1.69–9.29, P = 0.001) compared to elective surgery as significant risk factors, while emergency surgery was the only significant variable for shunt failure on multivariate regression analysis (OR 3.3, 95% CI 1.16–9.35, P = 0.025). Conclusion: Longer duration of surgery, less experience of the surgeon, and the priority of the case (emergency) were independent risk factors for shunt complications.

Abstract
PURPOSE To determine the outcome of ventriculo-peritoneal shunts as a treatment for idiopathic intracranial hypertension (IIH) Materials and Methods: Retrospective case series of 28 patients with IIH and evidence of raised intracranial pressure (ICP) who underwent shunt insertion. Patients were identified from a prospectively updated operative database. A case-notes review was performed and data on type of shunt, pre- and post-operative symptoms, ophthalmological findings and post-operative complications were recorded. RESULTS All patients had symptoms of IIH that had failed medical management. Twelve patients had previous lumbo-peritoneal shunts and 2 patients had previous venous sinus stents. All patients had evidence of raised ICP as papilloedema and raised CSF pressure on lumbar puncture. Twenty-seven patients received a ventriculo-peritoneal shunt and 1 patient a ventriculo-atrial shunt. Twenty-six patients received Orbis Sigma Valves and 2 patients Strata valves. At follow-up all patients (100%) had improvement/resolution of papilloedema, 93% had improved visual acuity and 84% had improved headaches. Mean time to last follow-up was 15 (range 4-96) months. Complications occurred in 3 patients (11%): 2 patients required revision of their peritoneal catheters and 1 patient had an anti-siphon device inserted. CONCLUSIONS Previous literature reported a ventricular shunt revision rate of 22-42% in the management of IIH. We demonstrate ventriculo-peritoneal shunts to be an effective treatment with a revision rate of 11% compared to the previously reported 22-42%.

Abstract
OBJECTIVE Placing of a ventriculoperitoneal shunt (VPS) is one of the most common procedures performed by neurosurgeons. Surgical revision of VPS is a significant cause of patient morbidity and mortality. This study was aimed to provide an analysis of factors related to VPS failures in the first 30 postoperative days in a pediatric cohort. METHODS This was a retrospective cohort study of 83 pediatric patients (<18 years old), shunted for the first time at a referral care center, between January 2012 and December 2016. Univariate analysis was used to detect potential predictors of VPS failures within the first 30 postoperative days and in the first 6 months of follow-up. Kaplan-Meier survival curves were used to examine the occurrence of VPS failures over time. RESULTS During the first 30 postoperative days, VPS failures occurred in 21 patients (25.3%). Intraventricular hemorrhage (IVH) (odds ratio [OR], 4.41; 95% confidence interval [CI], 1.44-13.48), cerebrospinal fluid (CSF) alterations (OR, 5.11; 95% CI, 1.37-19.1), and previous external ventricular drain (EVD) (OR, 7.05; 95% CI, 1.18-41.8) were significantly associated with shunt failure during the first postoperative month. Kaplan-Meier survival analysis showed decreased shunt survival for patients with IVH, both during the first 30 days after surgery (P = 0.005, log-rank), and during the 6 months after surgery (P = 0.005, log-rank). CONCLUSIONS In this study, we found that in pediatric patients, IVH was associated with VPS failure within the first 30 postoperative days and decreased shunt survival over time. Further larger prospective randomized studies are needed to better understand these results.

Abstract
OBJECTIVE To revalidate the craniometric dimensions of classic posterior burr holes for ventricular catheter insertion in hydrocephalic patients, based on ideal catheter position on a 3-dimensional simulated computed tomography (CT) reconstruction model of the ventricles. METHODS Fifteen patients with hydrocephaly underwent multislice, thin-cut CT to geometrically determine the Cartesian coordinates of a new point for optimal posterior ventricular catheterization. The success rate for ventricular puncture and the thickness of brain traversed by the catheter with 3 approaches (Frazier, Keen, and the suggested point) were compared. RESULTS The suggested burr hole point for posterior ventricular catheterization is 51 and 57 mm posterior and 58 and 60 mm above the external auditory meatus parallel to the orbitomeatal plane on the right and left sides, respectively, significantly different from the classical Frazier and Keen points. The success rate was 100% for approaches using the suggested point and the Frazier point, compared with 83% using the Keen point. This 17% difference was marginally significant (P = 0.052). The parenchymal mantle for the Frazier point was thicker than that of the suggested point on both sides, although the difference was statistically significant only on the right side (P = 0.006). The parenchymal mantle was thinner in the Keen approach compared with the suggested approach, but the difference was not statistically significant. CONCLUSIONS The use of a suggested burr hole point for posterior ventricular catheterization may decrease the amount of parenchymal mantle of the brain transgressed by the catheter, and may marginally improve the chance of successful posterior ventricular catheterization.

Abstract
OBJECTIVE Experience has led us to suspect an association between shunt malfunction and recent abdominal surgery, yet information about this potential relationship has not been explored in the literature. The authors compared shunt survival in patients who underwent abdominal surgery to shunt survival in our general pediatric shunt population to determine whether such a relationship exists. METHODS The authors performed a retrospective review of all cases in which pediatric patients underwent ventriculoperitoneal shunt operations at their institution during a 7-year period. Survival time in shunt operations that followed abdominal surgery was compared with survival time of shunt operations in patients with no history of abdominal surgery. Univariate and multivariate analyses were used to identify factors associated with failure. RESULTS A total of 141 patients who underwent 468 shunt operations during the period of study were included; 107 of these 141 patients had no history of abdominal surgery and 34 had undergone a shunt operation after abdominal surgery. Shunt surgery performed more than 2 weeks after abdominal surgery was not associated with time to shunt failure (p = 0.86). Shunt surgery performed within 2 weeks after abdominal surgery was associated with time to failure (adjusted HR 3.6, 95% CI 1.3-9.6). CONCLUSIONS Undergoing shunt surgery shortly after abdominal surgery appears to be associated with shorter shunt survival. When possible, some patients may benefit from shunt placement utilizing alternative termini.

Abstract
Although cerebrospinal fluid (CSF) shunt placement is the most common procedure performed by pediatric neurosurgeons, shunts remain among the most failure-prone life-sustaining medical devices implanted in modern medical practice. This article provides an overview of the mechanisms of CSF shunt failure for the 3 most commonly employed definitive CSF shunts in the practice of pediatric neurosurgery: ventriculoperitoneal, ventriculopleural, and ventriculoatrial. The text has been partitioned into the broad modes of shunt failure: obstruction, infection, mechanical shunt failure, overdrainage, and distal catheter site-specific failures. Clinical management strategies for the various modes of shunt failure are discussed as are research efforts directed towards reducing shunt complication rates. As it is unlikely that CSF shunting will become an obsolete procedure in the foreseeable future, it is incumbent on the pediatric neurosurgery community to maintain focused efforts to improve our understanding of and management strategies for shunt failure and shunt-related morbidity.
