Objective: Leptomeningeal metastasis (LM) is associated with altered CSF flow dynamics in 50%-70% of patients. Approximately 1%-5% of patients develop symptomatic LM-associated hydrocephalus (LM-H), which adversely impacts quality of life (QOL), functional status, and overall survival (OS). There is equipoise for CSF diversion procedures in LM-H. This systematic review and meta-analysis aimed to assess the effect of CSF diversion on OS and QOL in this context.
Methods: This systematic review was conducted according to the PRISMA guidelines. PubMed/Medline, Embase, Web of Science, and Scopus were searched for articles that evaluated the role of CSF diversion for LM-H due to systemic cancer in adult patients. A meta-analysis was conducted using random effects models, with mean differences and 95% CIs reported. Bias was assessed using the Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) tool.
Results: Ten eligible studies with a total of 494 patients were included. Two studies reported multivariate HRs for median OS, suggesting no significant effect of shunting on OS (pooled HR 0.42, 95% CI 0.09-1.94, p = 0.27). A difference between preoperative and postoperative Karnofsky Performance Status of mean 17.6 points (95% CI 10.44-24.68, p < 0.0001) was calculated from 4 studies. Across all studies, a symptomatic improvement rate of 67%-100% was observed, with high rates of improvement for headaches and nausea and lower rates for cranial nerve palsies. Complication rates across 9 studies ranged from 0% to 21.1%.
Conclusions: Based on the present findings, shunting does not improve OS but does relieve symptoms, suggesting that individuals who exhibit certain symptoms should be considered for CSF diversion. The present findings prompt the generation of a standardized decision-making tool and a critical analysis of the individual patient risk-benefit ratio. Implementation of these will optimize surgical management of LM-H patients.

Background: Aneurysmal subarachnoid hemorrhage (aSAH) carries a high economic cost and clinical morbidity in the United States. Beyond prolonged admissions and poor post-injury functional status, there is an additional cost of chronic shunt-dependent hydrocephalus for many aSAH patients. Adjuvant lumbar drain (LD) placement has been hypothesized to promote clearance of subarachnoid blood from the cisternal space, with an ultimate effect of decreasing shunt placement rates.

Introduction: Diffuse intrinsic pontine glioma (DIPG) in children comprises 80% of brainstem gliomas. In 2021, 5th edition of WHO CNS tumor classification defined H3K27M altered diffuse midline gliomas (DMGs) which replaced this entity. Lesion location precludes resection and the only current option available is radiotherapy.

Background: Post-hemorrhagic hydrocephalus (PHH) is a severe complication in premature infants following intraventricular hemorrhage (IVH). It is characterized by abnormal cerebrospinal fluid (CSF) accumulation, disrupted CSF dynamics, and elevated intracranial pressure (ICP), leading to significant neurological impairments.
Objective: This review provides an overview of recent molecular insights into the pathophysiology of PHH and evaluates emerging therapeutic approaches aimed at addressing its underlying mechanisms.

Purpose: Pediatric hydrocephalus imposes a significant clinical and financial burden in developing countries. Traditional treatment by ventricular shunting in this setting suffers a high rate of shunt infection and malfunction. This study aims at assessing the efficacy and safety of endoscopic third ventriculostomy (ETV), either alone or combined with choroid plexus cauterization (CPC), for preventing shunt dependence in pediatric hydrocephalus within a healthcare setting of a tertiary hospital in Egypt.

A syrinx involves cystic dilation of the central canal of the spinal cord due to the accumulation of cerebrospinal fluid and often results in a neurological deficit. While treatment options vary, surgical management is often utilized and requires an open durotomy.
