Abstract
OBJECTIVE Reported rates of failures of internal cerebrospinal fluid shunt (ICSFS) vary greatly from less than 5% to more than 50% and no meta-analysis to assess the overall prevalence has been performed. We estimated the failure rate after ICSFS insertion and searched for associated factors. METHODS Six databases were searched from January 1990 to February 2022. Only original articles reporting the rate of adult shunt failure were included. Random-effects meta-analysis with a generalized linear mixed model method and logit transformation was used to compute the overall failure prevalence. Subgroup analysis and meta-regression were implemented to search for associated factors. RESULTS Of 1763 identified articles, 46 were selected, comprising 70,859 ICSFS implantations and 13,603 shunt failures, suggesting an accumulated incidence of 19.2%. However, the calculated pooled prevalence value and its 95% confidence interval (CI) were 22.7% (95% CI, 19.8-5.8). The CI of the different estimates did not overlap, indicating a strong heterogeneity confirmed by a high I2 of 97.5% (95% CI, 97.1-97.8; P < 0.001; τ2 = 0.3). Ninety-five percent prediction interval of shunt failure prevalence ranged from 8.75% to 47.36%. A meta-regression of prevalence of publication found a barely significant decreasing failure rate of about 2% per year (-2.11; 95% CI, -4.02 to -0.2; P = 0.031). CONCLUSIONS Despite being a simple neurosurgical procedure, ICSFS insertion has one of the highest risk of complications, with failure prevalence involving more than 1 patient of 5. Nonetheless, all efforts to lower this high level of shunt failure seem to be effective.

Abstract
AbstractBACKGROUNDHydrocephalus after nontraumatic subarachnoid hemorrhage (SAH) is a common sequela that may require the placement of ventriculoperitoneal shunts (VPS). Adjustable-pressure valves (APVs) are being widely used in this situation though more expensive than differential-pressure valves (DPVs).OBJECTIVETo compare outcomes between APV and DPV in SAH-induced hydrocephalus.METHODSWe performed a retrospective chart review of patients with nontraumatic SAH who underwent VPS placement for the treatment of hydrocephalus after SAH, between July 2007 and December 2016. Patients were classified according to the type of valve (APV vs DPV). We evaluated factors that could predict the type of valve used, outcomes in VPS revision/replacement rate, and complications.RESULTSA total of 66 patients underwent VPS placement who were equally distributed into the 2 groups of valves. VPS failure with the need for revision/replacement occurred in 13 (19.7%) cases. Ten (30.3%) patients with DPV had a VPS failure, while 3 (9.1%) patients with an APV had a similar failure with the need for revision/replacement (P = .03). VPS placement before discharge during the initial hospitalization (P = .02) was statistically significant associated with the use of a DPV, while the reason of external ventricular drain (EVD) failure (P = .03) was associated with the use of an APV.CONCLUSIONAPVs had a lower rate of surgical revisions compared to DPVs. Early placement of VPS was associated with the use of a DPV. The need for EVD replacement due to EVD infection or malfunction was associated with higher rates of APV use.

Abstract
OBJECTIVE To investigate malfunctioning of ventriculoperitoneal shunt (VPS) valves in patients with brain tumors compared with patients with VPS for nontumoral etiologies to identify risk factors for shunt malfunction. METHODS Medical charts of all adult patients who underwent VPS surgery for hydrocephalus between 2011 and 2016 were reviewed. Incidence and risk factors for revision surgery due to valve malfunction were identified in patients with brain tumors (group A) and patients without brain tumors (group B). RESULTS Group A comprised 89 patients, and group B comprised 164 patients. The median follow-up time was 17 months for the entire cohort (9.4 months for group A vs. 25 months for group B, P < 0.001). VPS revision was performed in 60 patients (23.7%); 11 revisions involved valve failures necessitating valve replacement. Valve failures were significantly more common in group A (10 group A patients vs. 1 group B patient, P < 0.001). The distal or proximal shunt revision rate for reasons other than the valve was similar for both groups. Group A patients had a significantly higher cerebrospinal fluid protein level (44.5 mg/dL vs. 27.79 mg/dL, P < 0.05), and patients with valve failure had a 3-fold higher cerebrospinal fluid protein level compared with group A patients who experienced any type of shunt failure (96.3 mg/dL vs. 30.6 mg/dL, P < 0.05). CONCLUSIONS Shunt malfunction occurred mainly in patients with brain tumors and high cerebrospinal fluid protein levels. These patients are at high risk of valve failure and should be closely observed for emergent valve revision.

Abstract
INTRODUCTION Hydrocephalus (HC) occurs due to multiple origins. Time course and dynamic of HC and its therapies differ between underlying pathologies. Different revision rates due to the type of HC are expected. Though hydrocephalus is known to be a life time condition, the lack of shunt malfunction years or decades after initial shunt insertion raises the hope of a superfluous shunt. METHODS We conducted a retrospective survey of our OR-database during a 10 year period. All newly inserted shunt systems and subsequent shunt revisions are recorded according to quantity and time point. All patients were subdivided according their aetiology of HC. RESULTS 260 patients were eligible with a follow-up of 4.5 years. Subgroups were: 90 patients with NPH, 76 patients with posthaemorrhagic and 16 patients had posttraumatic HC. 22 received a shunt as a consequence of a tumour, 41 were children and 15 for other causes. Overall revision rate was 39.5%. During the first 6 months 55.6%, 57.9% and 75% of patients with NPH, posthaemorrhagic and posttraumatic HC had revisions. In contrast only 38.1% of children and 20% of tumour cases required early revision. CONCLUSION Two different patterns of revision are evident: mainly early revisions in morphologically stable diseases such as posthaemorrhagic, posttraumatic and NPH and predominantly late revisions in changing organisms such as children and tumour patients. The conception HC may be transient because of a lack of late revisions cannot be supported by this data.

Abstract
Objective Meningioma is a common intracranial tumor that predisposes patients to hydrocephalus which may require a permanent cerebrospinal fluid (CSF) diversion procedure such as ventriculoperitoneal (VP) shunts. We reviewed our long-term experience with VP shunts for the management of hydrocephalus in patients with meningioma. Methods and Materials A total of 48 Patients with meningioma who underwent VP shunt insertion for hydrocephalus from 1990 to 2013 was included in our case series. The study population was evaluated clinically and radiographically after VP shunt placement. Results Overall shunt failure was seen in 13 (27%) patients. Single and multiple shunt revisions were required in eight (16.7%) and five (10.4%) patients, respectively. The overall shunt revision within 6 months, 1 , and 5 years was 19, 23, and 27%, respectively. Male patient was significantly associated with the longer survival after shunt placement. Revisions free survival after 3, 5, 10, and 15 years of VP shunt placement were 70, 46, 30, and 20%, respectively. Finally, in regression analysis, age greater than 65 years (p = 0.02, 95% confidence interval (CI) = 0.1-0.13), tumor in posterior fossa (p < 0.0001, 95% CI = 0.1-0.23), tumor size (> 5 cm) (p = 0.3, 95% CI = 0.01-0.19), and Simpson resection grades II to IV (p = 0.04, 95% CI = 0.07-0.2) were identified as positive predictors of requirement of CSF flow diversion Conclusion The findings of the present study reveal that VP shunting is an important treatment option for the management of hydrocephalus in patients with meningioma. Further studies using less invasive techniques are warranted to compare the benefits of VP shunt for the management of hydrocephalus.

Valved or valveless ventriculoperitoneal shunting in the treatment of post-haemorrhagic hydrocephalus: a population-based consecutive cohort study. Acta Neurochir (Wien) 2016; 158:261-70; discussion 270. [PMID: 26668079 DOI: 10.1007/s00701-015-2659-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2015] [Accepted: 12/02/2015] [Indexed: 10/22/2022]
Abstract
BACKGROUND Implant infection and obstruction are major complications for ventriculoperitoneal shunts in patients with post-haemorrhagic hydrocephalus. In an effort to (1) reduce the incidence of these complications, (2) reduce the rate of shunt failure and (3) shorten the duration of neurosurgical hospitalisation, we have implemented valveless ventriculoperitoneal shunts at our department for adult patients with post-haemorrhagic hydrocephalus and haemorrhagic cerebrospinal fluid at the time of shunt insertion. METHODS All adult patients (>18 years old) treated for post-haemorrhagic hydrocephalus with ventriculoperitoneal shunting at our institution from 1 January 2008 to 31 December 2014 were included in this retrospective population-based consecutive cohort study. Data were collected by retrospectively reviewing medical records. We compared two different shunt modalities (valveless vs valve-regulated), analysing frequencies of complications, shunt survival and duration of neurosurgical hospitalisation. RESULTS A total of 214 patients aged 22-86 (mean age, 60.5 ± 11.5 years) were included, comprising 137 valveless and 77 valve-regulated shunts. We found no difference in the rate of surgical shunt revision (p = 0.65) or differences in time interval from insertion to first surgical revision (p = 0.31) between the two shunt modalities. The duration of neurosurgical hospitalisation was shorter for patients receiving a valveless shunt (p = 0.004). Patients with valveless shunts had a lower rate of shunt infection (5.1 % vs 14.3 %, p = 0.02), but a higher rate of overdrainage (10.3 % vs 2.6 %, p = 0.04). CONCLUSION The use of a valveless shunting for patients with post-haemorrhagic hydrocephalus results in shorter duration of neurosurgical hospitalisation and lower rate of shunt infection, although these advantages should be held up against the risk of overdrainage. We propose valveless shunting to be used as first-line shunting strategy in this patient category, with careful follow-up ensuring that these are substituted by a valve-bearing system if necessary.

Abstract
Approximately 1-5% of patients with cerebral metastasis and ~40% of patients with primary brain tumors suffer from hydrocephalus. These patients often exhibit a poor prognosis. The aim of the present study was to reassess the validity of ventriculoperitoneal shunting (VPS) with the assistance of the general surgeon in oncological patients. A total of 59 patients underwent first-time VPS at the Beth Israel Deaconess Medical Center (Boston, USA) between 2004 and 2012; 40 patients had hydrocephalus from brain metastasis and 19 from primary tumors. The analyzed independent variables included demographics, body mass index, past medical history, clinical presentation, indication for surgery, Karnofsky performance status (KPS) score and surgical technique; the dependent variables were postoperative symptoms and occurrence, cause and time of shunt failure. The outcomes were analyzed with the t-test and Kaplan-Meier estimates for shunt survival. The mean age of the patients was 57.2 years and the mean operative time was 50.4 min. Symptomatic palliation was achieved in 93% of the cases; patients with severe symptoms, such as debilitating headaches, nausea and vomiting, benefited significantly from VPS. The mean follow-up time was 6.3 months; complications occurred in only 7 patients (11.8%) during follow-up: 2 in the proximal shunt (1 infection and 1 obstruction), both requiring revision, 1 infection in the distal catheter requiring shunt removal, 2 cases of intracerebral bleeding that were monitored with computed tomography scans, 1 wound infection treated with antibiotics and 1 valve complication that required temporary revision. The initial and 3-month KPS scores were 65±16.4 and 75±16.0, respectively. The mean overall shunt survival was 6.4 months (range, 1.0 day-76.0 months) from the placement of the VP shunt. At 3 months after VPS, 93.5% of the patients remained alive with functioning shunts and at 1 year 87% of the shunts were still functioning. In conclusion, VPS remains a valid option for cancer patients with low KPS, as it improves the quality of life in such patients, even in the setting of previous infection, hemorrhage, or leptomeningeal disease, since shunt patency outlasts the overall survival of nearly all patients.

Abstract
OBJECTIVES Acute hydrocephalus ensues from various intracranial processes and is usually treated using external ventricular drainage (EVD). After the acute phase, a clamp trial is usually performed to identify patients requiring permanent CSF shunting. The aim of our study was to identify simple and clinically accessible factors that can help predict the result of the EVD clamp trial. METHODS 86 patients were selected for this retrospective analysis. Average CSF drained volume over 3 days given a constant EVD pressure level of 15 cm H2O and other clinical and laboratory parameters were statistically compared with the result of an EVD clamp trial. RESULTS The univariate analysis identified significant differences between the groups of patients who failed or passed the EVD clamp trial for the mean daily drained volume over 3 days (Mann-Whitney U-test, p<0.01). In the multivariate logistic regression, the average daily CSF output over 3 days was also significant (p=0.02), no other significant factors could be identified. Using hierarchical clustering, the best threshold daily value for EVD clamp trial failure was found at 130 ml (mean daily drained CSF volume) with the sensitivity of 64.5% and specificity of 83.6% (chi-square 20.6, p<0.01). CONCLUSION We have identified a simple, clinically available factor for identifying patients who are likely to fail the EVD clamp trial.

Abstract
Background: Between 2005 and 2010, we treated patients with hydrocephalus related to cerebral metastases, who were not good candidates for surgical resection by either endoscopic third ventriculostomy (ETV) or ventriculoperitoneal shunting (VPS). Patients were excluded from ETV if they had a clinical history suggestive of non-obstructive hydrocephalus, including: (1) history of infection or ventricular hemorrhage and (2) leptomeningeal carcinomatosis. The rest of the patients were treated with VPS. Methods: We analyzed the clinical outcome of these patient cohorts, to determine whether the efficacy of VPS was compromised due to a history of infection, ventricular hemorrhage, or leptomeningeal carcinomatosis, and compared these results to those patients who underwent ETV. Results: Sixteen patients were treated with ETV and 36 patients were treated with VPS. The overall efficacy of symptomatic palliation was comparable in the ETV and VPS patients (ETV = 69%, VPS = 75%). In both groups, patients with more severe hydrocephalic symptoms such as nausea, vomiting, and lethargy were more likely to benefit from the procedure. The overall complication rate for the two groups was comparable (ETV = 12.6%, VPS = 19.4%), although the spectrum of complications differed. The overall survival, initial Karnofsky performance status (KPS), and three-month KPS, were similarly comparable (median survival: ETV 3 months, VPS 5.5 months; initial KPS: ETV = 66 ± 7, VPS = 69 ± 12; 3 months KPS: ETV = 86 ± 7, KPS = 84 ± 12). Conclusion: VPS remains a reasonable option for poor RPA grade metastasis patients with hydrocephalus, even in the setting of a previous infection, hemorrhage, or in those with leptomeningeal disease. Optimal treatment of this population will involve the judicious consideration of the relative merits of VPS and ETV.

Abstract
OBJECTIVE Ventriculoperitoneal shunt surgery remains the most widely accepted neurosurgical procedure for the management of hydrocephalus. However, shunt failure and complications are common and may require multiple surgical procedures during a patient's lifetime. The purpose of this study is to evaluate the ventriculoperitoneal shunt surgery and the incidence of shunt revision in adult patients with hemorrhage-related hydrocephalus. METHODS Adult patients who underwent ventriculoperitoneal shunt placement for hemorrhage-related hydrocephalus from October 1990 to October 2009 were included in this study. Medical charts, operative reports, imaging studies, and clinical follow-up evaluations were reviewed and analyzed retrospectively. RESULTS A total of 133 adult patients with the median age of 54.5 years were included. Among patients, 41% were males, and 62% Caucasians. The overall shunt revision rate was 51.9%. The shunt revision rate within the first 6 months after the initial placement of ventriculoperitoneal shunts was 45.1%. The median time to first shunt revision was 0.50 (95% CI, 0.24-9.2) months. No significant association was observed between perioperative variables (gender, ethnicity, hydrocephalus type, or hemorrhage type) and the shunt revision rate in these patients. Major causes of shunt revision include infection (3.6%), overdrainage (7.6%), obstruction (4.8%), proximal shunt complication (7.6%), distal shunt complication (3.6%), old shunt dysfunction (6.8%), valve malfunction (10.0%), externalization (3.6%), shunt complication (12.0%), shunt adjustment/replacement (24.0%) and other (16.4%). CONCLUSION Although ventriculoperitoneal shunting remains to be the treatment of choice for adult patients with post hemorrhage-related hydrocephalus, a thorough understanding of predisposing factors related to the shunt failure is necessary to improve treatment outcomes.

Abstract
BACKGROUND Few studies have compared the incidence of ventricular shunt placement for hydrocephalus after clipping versus coiling of cerebral aneurysms. OBJECTIVE The Nationwide Inpatient Sample (NIS) database was used to compare, on a national level, the incidence of ventricular shunt placement after clipping versus coiling of ruptured and unruptured aneurysms. METHODS Hospitalizations for clipping and coiling of ruptured and unruptured aneurysms from 2002 to 2007 were collected from the NIS by cross-matching International Classification of Diseases-9 codes for diagnoses of subarachnoid hemorrhage or unruptured cerebral aneurysm with procedure codes for clipping or coiling. The incidence of ventricular shunt placement for hydrocephalus after clipping and coiling was compared using generalized linear models with generalized estimating equations (GEE) to adjust for patient- and hospital-specific factors and correlation between admissions. RESULTS Of 10,899 ruptured aneurysm patients (6593 clipping, 4306 coiling), clipping had a similar incidence of ventricular shunt placement (9.3%) compared to coiling (10.5%) (odds ratio = 0.984; 95% confidence interval = 0.85, -1.14; P value = 0.833 after adjustment for patient-specific and hospital-specific factors). Likewise, of 9686 unruptured aneurysm patients (4483 clipping, 5203 coiling), clipping had similar incidence of ventricular shunt placement (0.4%) compared to coiling (0.5%) (odds ratio = 0.763; 95% confidence interval = 0.37, -1.58; P value = 0.465 after adjustment for patient-specific and hospital-specific factors). Predictors of shunt placement in ruptured aneurysm patients were age, comorbidity score, admission type, payer, and hospital aneurysm volume. Predictors of shunt placement in unruptured aneurysm patients were comorbidity score and admission type. CONCLUSIONS In an observational study, clipping and coiling of ruptured and unruptured cerebral aneurysms are associated with similar incidences of ventricular shunt placement for hydrocephalus.

Abstract
BACKGROUND Endoscopic third ventriculostomy (ETV) is increasingly used in the treatment of obstructive hydrocephalus. The literature supporting its use in the setting of metastatic disease, however, remains limited. METHODS Between 2005 and 2010, 16 patients underwent ETV for treatment of obstructive hydrocephalus secondary to cerebral metastasis. Efficacy of symptomatic palliation and associated complications were reviewed. The results were compared to reported data for ventriculoperitoneal shunt placement in adult brain tumor patients. Patient selection criteria for ETV are reviewed. RESULTS Eleven of the 16 patients experienced symptomatic improvement after ETV (69%). Patients who presented with headache associated with nausea, vomiting, or lethargy were more likely to respond to treatment relative to patients presenting with headache alone. Of the 16 ETV patients, one suffered a wound infection and another underwent external ventricular drainage for assessment of intracranial pressure, yielding an overall complication rate of 12.5%. CONCLUSIONS In select patients with obstructive hydrocephalus related to cerebral metastasis, ETV constitutes a minimally invasive palliative option. The efficacy of ETV in this population is comparable to those reported for obstructive hydrocephalus secondary to primary cerebral neoplasm or other non-neoplastic causes. Patients receiving chemotherapy close to the time of ETV may be at increased risk for infection.
