Abstract
Objective This study aimed to examine potential risk factors associated with cerebrospinal fluid overdrainage after ventriculoperitoneal (VP) shunting. Materials and Methods We retrospectively examined the medical records of hydrocephalus patients who underwent VP shunting at a single institution between January 2011 and December 2017 and had a minimum 3-year follow-up. Variables studied included age, gender, hydrocephalus etiology, symptoms, shunt valve, ventricular catheter entry point, and neurosurgical history, including history of external ventricular drainage. Radiographic variables included Evans index, bicaudate index, callosal angle, measurements of frontal lobe thickness, and bifrontal-parietal ratio. Results Among the 182 study patients, 11 experienced overdrainage. Age, gender, etiology, symptoms, and surgical history did not significantly differ between patients who experienced overdrainage and those who did not. Evans index, bicaudate index, and callosal angle did not significantly differ between the groups. Measurements of frontal lobe thickness and bifrontal--parietal ratio were significantly lower in the overdrainage group. Conclusion Bifrontal-parietal ratio may be useful to predict overdrainage after VP shunt surgery.

Abstract
Objective This study aimed to evaluate the functional outcomes of lumboperitoneal (LP) shunt for the treatment of non-obstructive hydrocephalus. Methods We retrospectively studied the clinical surgical results of 172 adult patients with hydrocephalus who underwent LP shunt surgery between June 2014 and June 2019. Data regarding the following were collected: pre- and postoperative symptom status, third ventricle width changes, Evans index, and postoperative complications. Additionally, the baseline and follow-up Glasgow Coma Scale (GCS) score, Glasgow Outcome Scale (GOS), and Modified Rankin Scale (mRS) scores were investigated. All patients were followed up for ≥12 months using clinical interview and braining imaging using computed tomography (CT) scan or magnetic resonance imaging (MRI). Results Majority of patients presented with normal pressure hydrocephalus as the etiology of their disease (48.8%), followed by cardiovascular accident (28.5%), trauma (19.7%), and brain tumor (3%). The mean GCS, GOS, and mRS improved postoperatively. The average period from symptomatic onset to surgery was 402 days. The average width of the third ventricle on CT scan or MRI was 11.43 mm preoperatively and 10.8 mm postoperatively (P<0.001). The Evans index improved from 0.258 to 0.222 after operation. The symptomatic improvement score was 7.0, with a complication rate of 7%. Conclusion Significant improvement was observed in the functional score and brain image after LP shunt placement. Moreover, the satisfaction with symptomatic improvement after surgery remains high. LP shunt operation is a viable alternative in the treatment of non-obstructive hydrocephalus due to the low complication rate, fast recovery, and high satisfaction.

Association of Preoperative Cerebrospinal Fluids Parameters With Early Shunt Obstruction in Patients With Post-hemorrhagic Hydrocephalus Treated by Lumboperitoneal Shunt. Front Neurol 2021; 12:693554. [PMID: 34526955 PMCID: PMC8435900 DOI: 10.3389/fneur.2021.693554] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 08/04/2021] [Indexed: 02/05/2023] Open
Abstract
Background: Early shunt obstruction (SO) remains the most common cause of lumboperitoneal shunt (LPS) failure. Although there is anecdotal evidence that the level of cerebrospinal fluid (CSF) parameters might affect shunt performance, its association with early LPS obstruction in adults with post-hemorrhagic hydrocephalus (PHH) is unclear. Methods: The retrospective study was performed by reviewing the adults with PHH treated by LPS from years 2014 to 2018. We included patients with CSF samples analyzed within 1 week prior to shunt insertion or at the time of shunt insertion. Baseline characteristics of each patient were collected. The primary outcomes were the incidence rate and associated factors of SO occurring within 3 months of shunt placement. The secondary outcomes included scores on the National Institute of Health Stroke Scale (NIHSS) and Evans Index at discharge. Results: A total of 76 eligible patients were analyzed, of whom 61 were obstruction-free and 15 were early SO. The overall rate of early SO was 15.6%. The RBCs count and nucleated cells count in preoperative CSF were actually higher in patients with early SO, compared to patients in the control group. Multivariate analysis identified RBC elevation (>0 × 106/L; OR: 10.629, 95% CI: 1.238–91.224, p = 0.031) as a dependent risk factor for early SO. NIHSS dramatically decreased at discharge while the alteration of ventricular size was not observed. Conclusions: This study suggested that the presence of RBCs in preoperative CSF was associated with early SO in patients with PHH treated by LPS.

Abstract
INTRODUCTION Ventriculoperitoneal shunt (VPS) remains the most widely used methods to treat communicating hydrocephalus. More recently, lumboperitoneal shunt (LPS) has been suggested as a reasonable option in some studies. However, there is lack of high-quality studies comparing these two techniques in order to certain the benefits and harms to use one of these two methods. The purpose of the current study is to determine the effectiveness and safety of the LPS versus the VPS in patients with communicating hydrocephalus. METHODS AND ANALYSIS All eligible patients aged 18-90 years with communicating hydrocephalus will be recruited and then randomly allocated into LPS or VPS group in a ratio of 1:1. All patients will be analysed before shunt insertion, at the time of discharge, 1 month, 6 months, 12 months and 24 months postoperatively. The primary outcome measure is the rate of shunt failure at a 2-year follow-up term. The secondary outcomes include Keifer's Hydrocephalus Scale, National Institute of Health Stroke Scale, Glasgow Outcome Scale Extended, Evans index, safety endpoints and cost-effectiveness of hospital stay. ETHICS AND DISSEMINATION The study will be performed in compliance with the Declaration of Helsinki (2002) of the World Medical Association. The study was approved by Institutional Review Board of West China Hospital. All patients will be fully informed the potential benefits, potential risks and responsibilities, those who will sign the informed consents once they are included. Preliminary and final results will be published in peer-reviewed journals and presented at national and international congresses. TRIAL REGISTRATION NUMBER ChiCTR2100043839.

Abstract
BACKGROUND The best treatment option for patients with post-hemorrhagic hydrocephalus (PHH) remains controversial. The objective of the current meta-analysis is to systematically evaluate the long-term outcomes of patients with PHH treated by ventriculoperitoneal shunt (VPS) and lumboperitoneal shunt (LPS). METHODS We search literatures through PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), the Chinese Science and Technology Periodical Database (VIP) and Wan fang databases, and Chinese Biomedical Literature Database (CBM) from its beginning to June 15, 2020. Randomized controlled trials (RCTs) and non-RCTs in English or Chinese studies will be considered. The primary outcome is the rate of shunt failure after shunt implantationThe secondary outcome is the rate of complications that are associated with shunt surgery. RESULTS AND CONCLUSION The study will compare the 2 types of shunt surgery in the treatment of PHH, providing evidence for the treatment option for the patients with PHH. STUDY REGISTRATION NUMBER The study is priorly registered through International Platform of Registered Systematic Review and Meta-analysis Protocols on June 17, 2020 (INPLASY202060063).

Abstract
BACKGROUND Ventriculoperitoneal shunt (VPS) surgery remains the most widely accepted and used option method to treat post-hemorrhagic hydrocephalus (PHH) worldwide while lumboperitoneal shunt (LPS) serves as an effectively alternative treatment. However, the outcomes of VPS and LPS in the treatment of PHH have not been compared in a prospective trial. METHODS AND DESIGN In this monocentric, assessor-blinded, non-randomized controlled trial, 75 eligible patients with PHH for each group will be recruited to compare the outcomes of VPS cohort with that of LPS cohort. Each participant is evaluated before surgery, at the time of discharge, 3, and 6 months after surgery by experienced and practiced assessors. The primary outcome is the rate of shunt failure 6 months after shunt surgery. The secondary measure of efficacy is National Institute of Health stroke scale, together along with Glasgow coma scale, modified Rankin Scale, and Evans index at the evaluation point. A favorable outcome is defined as shunt success with an improvement of more than 1 point in the National Institute of Health stroke scale. Complication events occurring within 6 months after surgery are investigated. A serious adverse events throughout the study are recorded regarding the safety of shunts. DISCUSSION The results of this trial will provide evidence for the treatment options for patients with PHH.
