The Role of Third Ventriculostomy in the Management of Obstructive Hydrocephalus

2003

Objective: Endoscopic third ventriculostomy (ETV) is an effective treatment for occlusive hydrocephalus caused by an obstruction of the CSF flow in the aqueduct or the posterior fossa. We evaluated the factors age, pathology and surgical technique on the results of the ETV. Methods: Between November 1992 and October 2000 171 ETV have been performed in 159 patients. The follow-up was evaluated in 150 patients. The age ranged from 10 days to 77 years (mean age 35 years). The hydrocephalus was caused by benign aqueductal stenosis in 77 patients, space-occupying lesions in 59, by intraventricular hemorrhages in 11, and by other causes in 3 patients. The trajectory was planned in 31 patients by …

A novel L1CAM mutation in a fetus detected by prenatal diagnosis

2010

X-linked hydrocephalus is due to mutations in the L1 neuronal cell adhesion molecule (L1CAM) gene. L1 protein plays a key role in neurite outgrowth, axonal guidance, and pathfinding during the development of the nervous system. We report on a familial case diagnosed by prenatal ultrasonographic examination, with cerebellar hypoplasia, agenesis of the corpus callosum, and the bilateral overlapping of the second and third fingers of the hand. Sequencing of the L1CAM gene showed a novel missense mutation in exon 14: transition of a guanine to cytosine at position 1777 (c.1777G > C), which led to an amino acid change of alanine to proline at position 593 (Ala593Pro) in the sixth immunoglobulin …

A Rare Case of Docetaxel-Induced Hydrocephalus Presenting with Gait Disturbances Mimicking and Coexisting with Taxane-Associated Polyneuropathy: The …

2017

Docetaxel constitutes a widely used chemotherapeutic agent as a first-line treatment for several neoplastic diseases. One of the most common side effects induced by this drug is polyneuropathy, which among other symptoms can cause gait disbalance. However, in exceptional cases gait disturbances could be related to docetaxel-induced hydrocephalus, a rare event that up to the present has been overseen throughout the medical literature and should be meticulously differentiated from polyneuropathy, since its clinical features, treatment, and prognosis differ drastically. We present the case of a woman with a progressive gait disturbance that started immediately after having been treated with do…

Cerebrospinal Fluid Dynamics Following Ventriculoperitoneal Shunt in Hydrocephalus: Do Technological Advancements Avoid Complications?

Intraoperative monitoring of cerebral blood flow during ventricular shunting in hydrocephalic pediatric patients.

1995

Several studies have demonstrated lowered cerebral blood flow (CBF) in patients with hydrocephalus and symptoms of raised intracranial pressure. Ventricular shunting in such cases permits a sudden increase in CBF. The pathophysiology of functional brain deficit secondary to hydrocephalus is little understood. Improvement of the patient's clinical status after drainage of CSF suggests that cerebral dysfunction is not necessarily due to permanent brain damage. In fact, it improves rapidly after ventricular taps. In view of this it would be helpful to monitor cerebral perfusion. The transcranial Doppler (TCD) ultrasonography technique allows real-time monitoring of the intracranial circulation…

Long-Term Follow-Up of Repeat Endoscopic Third Ventriculostomy in Obstructive Hydrocephalus.

2017

Endoscopic third ventriculostomy (ETV) is a safe and less-invasive treatment strategy for patients with obstructive hydrocephalus and provides excellent outcome. Nevertheless, repeat ETV in cases of ETV failure is a controversial issue.Between 1993 and 1999, 113 patients underwent a total of 126 ETVs at the Department of Neurosurgery, Mainz University Hospital. Obstructive hydrocephalus was the causative pathology in all cases. A very long-term follow-up of up to 16 years could be achieved. All medical reports of patients who received ETV were reviewed and analyzed with focus on ETV failure with following repeat ETV and its initial as well as very long-term success.Thirty-one events of ETV …

Long-Term Efficacy of Shunt Therapy in Idiopathic Normal Pressure Hydrocephalus.

2019

Background: Idiopathic normal pressure hydrocephalus (iNPH) is one of the very few treatable types of dementia. Shunt therapy has been shown to be effective in improving symptoms. However, the long-term results of cerebrospinal fluid diversion are variable. The aim of this retrospective study was to investigate long-term outcomes of patients with idiopathic normal pressure hydrocephalus treated with ventriculoperitoneal shunt by using programmable valves. Methods: Symptoms before treatment were recorded. Clinical symptoms and outcome after ventriculoperitoneal shunt were assessed based on changes in gait, urinary incontinence, and cognitive dysfunction at yearly follow-up spanning at least …

Cognitive, biochemical, and imaging profile of patients suffering from idiopathic normal pressure hydrocephalus

2011

Abstract Introduction It has still not been clearly established whether the cognitive deficits of idiopathic normal pressure hydrocephalus (iNPH) are caused by a disturbance in cerebrospinal fluid (CSF) dynamics or an underlying metabolic disturbance. Objective To identify the possible associations between biochemical markers, the neuroimaging characteristics, and cognitive deficits of patients undergoing investigations for possible iNPH. Methods A CSF sample obtained during a lumbar puncture from 10 patients with iNPH was analyzed for several biochemical markers (lactate, 8-isoprostane, vascular endothelial growth factor [VEGF], neurofilament heavy protein, glial fibrillary acidic protein,…

Chronic Adult Hydrocephalus

1974

Knowledge of Wallerian degeneration began in 1852 and, following experimental research on degeneration and regeneration of interrupted nerves, surgeons realized that reinnervation of end organs depended on growth of axons through the interrupted area of nerve. Therefore surgeons tried to reanastomose the stumps. Failures of reinnervation could not be blamed on lack of axoplasma metabolism and flow from cell body to suture line because the clinical observation of amputation neuromas and their constant recurrence demonstrated the unfailing delivery of axoplasma by the nerve cell body; at times to the deep concern of the surgeon, and the constant pain of the patient. The electron microscope sh…
