Background: Idiopathic intracranial hypertension (IIH) remains a poorly understood condition with no standardized treatment. Treatment is therefore generally individualized. Recent isolated reports have begun to describe the use of third ventriculostomy (open or closed) for the treatment of IIH. This review aims to communicate the current evidence for the use of third ventriculostomy in IIH.
Methods: A systemic review, using PubMed, was performed of studies describing the use of third ventriculostomy, either open or closed, for the treatment of idiopathic intracranial hypertension.
Results: Only 3 studies for a total of 3 patients were found in which a third ventriculostomy was performed for the treatment of IIH.
Conclusion: Despite very plausible proposed mechanisms of action, there is currently a paucity of both studies and, therefore, evidence for the use of either endoscopic or open third ventriculostomy for the treatment of IIH. The studies done to date do strongly suggest that further consideration is warranted.

Success Rate of Endoscopic Third Ventriculostomy in Children Younger Than 1 Year With Idiopathic Congenital Aqueductal Stenosis and Long-term Follow-up.

Introduction: The indication for endoscopic third ventriculostomy is often contested in children younger than 1 year. This study aims to establish the benefits of this modality in children with idiopathic congenital aqueductal stenosis.
Methods: Retrospective analysis was performed on patients <1 year old with idiopathic congenital aqueductal stenosis undergoing endoscopic third ventriculostomy between 2004 and 2020.

Objective: The current neurosurgical treatment for intraventricular hemorrhage (IVH) of prematurity resulting in posthemorrhagic hydrocephalus (PHH) seeks to reduce intracranial pressure with temporary and then permanent CSF diversion. In contrast, neuroendoscopic lavage (NEL) directly addresses the intraventricular blood that is hypothesized to damage the ependyma and parenchyma, leading to ventricular dilation and hydrocephalus. The authors sought to determine the feasibility of NEL in PHH.

A 54-year-old man presented with gait disturbances, urinary incontinence, and headache for 6 months. Head computed tomography indicated several high-density mass lesions in the quadrigeminal cistern, causing occlusive hydrocephalus. Digital subtraction angiography confirmed tentorial dural arteriovenous fistulae (AVF).

Postoperative fever following neuroendoscopic procedures has been well-documented, yet specific differentiation based on the nature and site of the procedure remains lacking. Given the anatomical involvement of the hypothalamus in temperature regulation, we propose that endoscopic third ventriculostomy (ETV) may have a distinct impact on postoperative fever. This study aims to investigate this phenomenon.

The widening of the vestibular dimension of lateral ventricles > 10 mm should be considered a symptom rather than a definitive diagnosis. In fact, fetal ventriculomegaly (VM) is a defect with 'multifaceted' clinical consequences in the child's further neurodevelopment. Isolated fetal ventriculomegaly can cause neurological defects ranging from mild neurodevelopmental delay to severe complications in the form of ongoing palliative care to the death of patients at various developmental periods.
