OBJECTIVE Shunt failure is common among patients undergoing ventriculoperitoneal shunting for treatment of hydrocephalus. The present study examined long-term shunt failure and associated risk factors in pediatric patients by using a national hospitalization database of Thailand. METHODS Patients 17 years or younger who had been admitted to 71 public hospitals in 2012–2017 for first-time ventriculoperitoneal shunting for diseases with known etiology and discharged alive were followed through 2019 to ascertain shunt failure. Shunt survivals were calculated using Kaplan-Meier estimates and time to failure was analyzed to identify risk factors for the first failure by using Cox proportional hazards regression. Differences in risks of subsequent failures with respect to place in the order of failures (i.e., first, second, third) were determined using a cumulative hazard function. RESULTS Over a median follow-up of 29.9 months, shunt failure occurred in 33.7% of 2072 patients (median age...
Factors associated with 30-day ventriculoperitoneal shunt failure in pediatric and adult patients
Journal of neurosurgery, 2018
OBJECTIVE The aim of this study was to provide a comprehensive benchmark of 30-day ventriculoperitoneal (VP) shunt failure rates for a single institution over a 5-year study period for both adult and pediatric patients, to compare this with the results in previously published literature, and to establish factors associated with shunt failure. METHODS A retrospective database search was undertaken to identify all VP shunt operations performed in a single, regional neurosurgical unit during a 5-year period. Data were collected regarding patient age, sex, origin of hydrocephalus, and whether the shunt was a primary or secondary shunt. Operative notes were used to ascertain the type of valve inserted, which components of the shunt were adjusted/replaced (in revision cases), level of seniority of the most senior surgeon who participated in the operation, and number of surgeons involved in the operation. Where appropriate and where available, postoperative imaging was assessed for grade o...
Late pediatric ventriculoperitoneal shunt failures: a Singapore tertiary institution's experience
Neurosurgical Focus, 2016
OBJECTIVE The introduction of ventriculoperitoneal shunts changed the way hydrocephalus was treated. Whereas much is known about the causes of shunt failure in the first few years, there is a paucity of data in the literature regarding the cause of late shunt failures. The authors conducted a study to find out the different causes of late shunt failures in their institution. METHODS A 10-year retrospective study of all the patients who were treated in the authors' hospital between 2006 and 2015 was conducted. Late shunt failures included those in patients who had to undergo shunt revision more than 5 years after their initial shunt insertion. The patient's notes and scans were reviewed to obtain the age and sex of the patient, the time it took for the shunt to fail, the reason for failure, and the patient's follow-up. RESULTS Forty-six patients in the authors' institution experienced 48 late shunt failures in the last 10 years. Their ages ranged from 7 to 26 years (1...
Analysis of factors affecting ventriculoperitoneal shunt survival in pediatric patients
Child's Nervous System, 2013
Purpose Management of hydrocephalus with insertion of ventriculoperitoneal (VP) shunt is associated with significant complications in both adult and pediatric patients. These may be more common in developing countries due to poor economic conditions and a dearth of available resources. We report a 6 years' experience with VP shunt insertion in pediatric patients from a developing country, focusing particularly on factors affecting shunt failure. Methods Patients aged below 15 years, who had undergone insertion of VP shunts for hydrocephalus during the years 2006 to 2011, were included. A retrospective analysis of shunt survival was performed using Kaplan-Meier curves and Logrank (Cox-Mantel) test. Results Among the total 113 patients, the most common etiologies of hydrocephalus were congenital hydrocephalus (19.5 %), brain tumors (14.2 %), and postcranial surgery (13.3 %). Overall shunt failure at a mean follow-up of 11 months was 23 % with the median time to first shunt failure being 68 days. Shunt survival was worse in patients with meningitis (p=0.024), aqueductal stenosis (p=0.008), postcranial surgery hydrocephalus (p=0.006), Caesarean mode of delivery (p=0.036), congenital abnormalities (p= 0.031), and a past history of surgical excision of mass lesion (p=0.044).Frequency of shunt failure was also significantly affected by the location of brain tumor (p=0.015) and prematurity (p=0.015). Conclusion Premature infants still have a higher rate of shunt failure. Patients with meningitis, aqueductal stenosis, postcranial surgery hydrocephalus, congenital abnormalities, and a past history of surgical excision of mass lesion may have early shunt failure. However, the frequency of shunt failure that we observed (23 %) was much lower than that quoted earlier in the literature and this may be a consequence of rigorous periodic evaluation of patients with VP shunt in situ.

Objectives Ventriculoperitoneal (VP) shunting is commonly used to treat pediatric hydrocephalus, but failure rates are high. VP shunt failure in children is mostly caused by infection and/or proximal/distal shunt obstruction. However, to our knowledge, no previous reviews have discussed this topic using only clinical studies when age-related data could be obtained. This systematic review aimed at reevaluating what is already known as the most common causes of shunt failure and to determine the incidence and causes of VP shunt failure during the first 2 years of life as a step to establish solid evidence-based guidelines to avoid VP shunt failure in infants. Methods We performed a search using the search terms “Cerebrospinal Fluid Shunts” (Medical Subject Headings [MeSH]) AND failure [All Fields] AND (“humans” [MeSH] AND English [lang] AND “infant” [MeSH]). Only articles that specifically discussed VP shunt complications in children < 2 years were included. Results We found that t...
Pediatric Ventriculoperitoneal Shunt: Outcome Analysis in a Tertiary Care Center in Nepal
2020
IntroductionVentriculoperitoneal (VP) shunt is a commonly performed neurosurgical procedure in pediatric surgical practice. It results in a dramatic improvement in patient survival and neurological function but is associated with several complications requiring multiple shunt revisions throughout a patient’s lifetime. The main aimof the study was to evaluate the outcome especially complications of shunt surgery at our center.MethodsA single-institutional, retrospective observational study was conducted in 60 operated cases of congenital hydrocephalus with a minimum follow-up for up to 6 months. Parameters for analysis included demographic data, etiology of hydrocephalus, surgery time, and type of complications.ResultsOut of 86 patients, 60 patients who fulfilled the inclusion criteria were enrolled in the study. The mean age of the patients at the time of VP shunt placement was 3 months, range from 8 days to 15 years with male preponderance. The majority of the patients belonged to ...
Comparison of Total versus Partial Revision of Initial Ventriculoperitoneal Shunt Failures
Pediatric Neurosurgery, 2002
Background: Optimal surgical management of patients presenting with shunt failure in the age of neuroendoscopy remains complex. The value of replacing the entire shunt system as opposed to a single shunt component has not been assessed. Methods: We reviewed the records of all pediatric patients who underwent their first shunt revision between January 1992 and December 1998. Patients with primary shunt failure attributed solely to proximal catheter obstruction or distal catheter obstruction were included for analysis. Shunt revisions were classified as total (entire shunt replaced) or partial (only malfunctioning component replaced). Kaplan-Meier (shunt survival curves) and log rank analysis were used to compare failure rates between partially and totally revised shunts according to the underlying diagnosis and failed shunt part. Significant differences in univariate analysis were confirmed with a multivariate proportional hazards regression model. Results: 301 pediatric patients und...

The major aims of this study were to estimate the infection rate and recognize the risk factor for ventriculoperitoneal (VP) shunt infections in children. To analyze shunt infection rate and identify risk factors, a retrospective cohort analysis of 333 consecutive VP shunt series was performed at Seoul National University Children's Hospital in Korea between January 2005 and February 2011. Overall, 35 shunts (10.5%) were infected, which represented an infection rate of 0.075 infection cases per shunt per year. VP shunt infection occurred at a median of 1 month (range, 6 days to 8 months) after insertion. An independent risk factor for shunt infection was undergoing an operation before the first year of life (relative risk 2.31; 95% confidence interval, 1.19-4.48). The most common causative microorganism was coagulase-negative staphylococci in 16 (45.7%) followed by Staphylococcus aureus in 8 (22.9%). Methicillin resistance rate was 83.3% among coagulase-negative staphylococci an...
