OBJECTIVES: Shunt implantation is an option in the treatment of hydrocephalus. However, the benefits and adverse effects of programmable shunt valves have not been well assessed. MATERIALS AND METHODS: Randomized controlled trials (RCTs) and observational studies assessing the efficacy and safety of programmable valves (PV) treatment for hydrocephalus were identified from electronic databases (PubMed, EMBASE, and Cochrane library). The meta-analysis was performed with the fixed-effect model or random-effect model according to heterogeneity...

Achondroplasia is the most common genetic form of human dwarfism, characterized by midfacial hypoplasia resulting in occlusal abnormality and foramen magnum stenosis, leading to serious neurologic complications and hydrocephalus. Currently, surgery is the only way to manage jaw deformity, neurologic complications, and hydrocephalus in patients with achondroplasia. We previously showed that C-type natriuretic peptide (CNP) is a potent stimulator of endochondral bone growth of long bones and vertebrae and is also a potent stimulator in the craniofacial region, which is crucial for midfacial skeletogenesis...

Yosef Laviv, Sergio Neto, Ekkehard M Kasper
Quadrigeminal arachnoid cysts (QAC) are usually accompanied by a symptomatic obstructive hydrocephalus. Several endoscopic and surgical treatments exist; however, the critical location of these cysts further complicates treatment and usually more than one procedure is required. In this report, a 31 year old female with QAC and associated obstructive hydrocephalus was successfully treated with stereotactic placement of a permanent ventricular - cystic stent (intraventricualr - cystic catheterization) in single - session...

Meningiomas are rare in the pediatric age group, more so in the intraventricular location. They arise in the lateral ventricles from the arachnoid cells contained within the choroid plexus, in the third ventricle from the velum interpositum and in the fourth ventricle from the choroids. These tumors are usually large and have an aggressive behaviour. Surgical management of intra-ventricular meningiomas is challenging because of their deep location, large size at presentation and increased vascularity. The authors report two such cases who presented with symptoms of raised intra cranial pressure and on evaluation were found to have associated hydrocephalus...

Receptors for advanced glycation end-products (RAGE) mediate the inflammatory reaction that follows aneurysmal subarachnoid haemorrhage. Soluble RAGE (sRAGE) may function as a decoy receptor. The significance of this endogenous anti-inflammatory mechanism in subarachnoid haemorrhage (SAH) remains unknown. The present study aims to analyse sRAGE levels in the cerebrospinal fluid (CSF) of SAH patients. sRAGE levels were assayed by ELISA kit in 47 CSF samples collected on post-SAH days 0-3, 5-7, and 10-14 from 27 SAH patients with acute hydrocephalus...

OBJECTIVE Posttraumatic hydrocephalus (PTH) affects 11.9%-36% of patients undergoing decompressive craniectomy (DC) and is an important cause of morbidity after traumatic brain injury (TBI). Early diagnosis and treatment of PTH can prevent further neurological compromise in patients who are recovering from TBI. There is limited data on predictors of shunting for PTH after DC for TBI. METHODS Prospectively collected data from the erythropoietin severe TBI randomized controlled trial were studied. Demographic, clinical, and imaging data were analyzed for enrolled patients who underwent a DC...

BACKGROUND: Cavum septum pellucidum (CSP) and cavum vergae are actually fluid-filled, generally communicating midline cavities located between the third ventricle and corpus callosum. There have been various reports of their association with many behavioral and psychiatric disorders. Infrequently, they have been associated with an obstructive hydrocephalus-like picture. Although the structure and management of CSP has long been known, it has been an enigma as far as functional significance and management indications are concerned...

BACKGROUND: Giant intracranial aneurysms (GIAs) can be approached via microsurgical and endovascular techniques. Utilization of flow diversion devices (FDDs) has yielded favorable outcomes, and indications for cerebral revascularization have dramatically decreased. OBJECTIVE: To evaluate the safety and validity of using internal maxillary artery (IMA) bypass with an interposed graft to treat GIAs. METHODS: During a 6-year period, high-flow IMA bypass procedures were performed in 32 patients with GIAs at our institute...

BACKGROUND: Choroid plexus tumors (CPT) in the pediatric population are usually discovered in symptomatic patients often with symptoms of increased intracranial pressure, with hydrocephalus as the most common presentation, along with seizures, subarachnoid hemorrhage, or focal neurological deficit. Most CPTs are found to be benign choroid plexus papillomas (CPP), whereas a small number are intermediate and malignant choroid plexus carcinomas (CPC). Total surgical resection is the established definitive treatment for symptomatic CPP...

Intra-ventricular hemorrhage (IVH) is a critical condition with high rate of morbidity and mortality due to acute hydrocephalus and secondary brain injury. Mechanisms underlining the clinical deterioration are not only related to the appearance of an acute hydrocephalus but also to blood- clot mass effect and the inflammatory effects of blood break-down products which impede local blood flow and exert a direct toxic effect on the peri-ventricular structures leading to chronic hydrocephalus. An effective treatment strategy should aim at IVH fast removal and reduction of blood-clot mass effect...

Background: Tuberculous meningitis (TBM) leads to death or disability in half the affected individuals. Tools to assess severity and predict outcome are lacking. Neuro-specific biomarkers could serve as markers of the severity and evolution of brain injury, but have not been widely explored in TBM. We examined biomarkers of neurological injury (neuromarkers) and inflammation in pediatric TBM and their association with outcome. Methods: Blood and cerebrospinal fluid (CSF) of children with TBM and hydrocephalus taken on admission and over 3 weeks were analysed for neuromarkers S100B, neuron-specific enolase (NSE) and glial fibrillary acidic protein (GFAP), and multiple inflammatory markers...

Myelomeningocele (MMC) is a costly lifetime disease with many comorbidities, including sensory and motor lower limb disability, bladder/bowel dysfunction, scoliosis, club foot, and hydrocephalus. MMC treatment options have changed over time because routine use of fetal ultrasonography and MRI has provided prenatal diagnosis and the potential for fetal surgery. There is still no consensus on how to treat the MMC diagnoses prenatally, mainly related to the infrastructure required to operate on pregnant patients...

OBJECTIVE The endoscopic third ventriculostomy (ETV) is an established and effective treatment for obstructive hydrocephalus. In its most common application, surgeons plan their entry point and the endoscope trajectory for the procedure based on anatomical landmarks, then control the endoscope freehand. Recent studies report an incidence of neural injuries as high as 16.6% of all ETVs performed in North America. The authors have introduced the ROSA system to their ETV procedure to stereotactically optimize endoscope trajectories, to reduce risk of traction on neural structures by the endoscope, and to provide a stable mechanical holder of the endoscope...

INTRODUCTION: The standard treatment for hydranencephaly and maximal hydrocephalus consists of inserting shunts, although complications frequently occur. Choroid plexus cauterization (CPC) is an alternative, but its long-term efficacy and the factors associated with the success and failure of controlling head circumference (HC) are not well defined. OBJECTIVE: This study aims to evaluate the long-term efficacy and factors related to the success rate of CPC in the treatment of hydranencephaly and maximal hydrocephalus...

INTRODUCTION: The precise incidence of hydrocephalus in patients with mucopolysaccharidoses (MPS) is hard to determine, because the condition lacks a formal, consensus-based definition. The diagnosis of hydrocephalus depends on symptom profile, presence of neuroimaging features, and the outcome of diagnostic tests. Although numerous techniques are used to identify MPS patients who are most likely to have hydrocephalus and respond to treatment, no definitive method exists to prove diagnosis...
