Background and Aims: The insertion of ventriculoperitoneal (VP) and ventriculoatrial (VA) shunts is the first-line treatment of patients with hydrocephalus and normal-pressure hydrocephalus. The provision of a safety profile for shunting in the treatment of hydrocephalus patients is very important. This study aimed to determine the success rates and complications of VP and VA shunting in patien...
We consider the situation of rearranging freight trains in a shunting yard with a hump and several tracks. Here, an elementary shunting operation is to push a all cars of one track over the hump. On the way back to the tracks the cars can be guided individually to an arbitrary track. The goal is to create one or several trains that have their cars in a particular order. We measure the efficienc...
treatment of hydrocephalus in posterior fossa tumors in children is still a matter of controversy and different centers have their own routines. in this regard, hospital records of all children with posterior fossa tumors treated in our center during the interval of 1985-1995 were reviewed. patients’ demographic and diagnostic data were analyzed and the frequencies of shunting procedures were d...
Hydrocephalus is an abnormal increase in the volume of cerebrospinal fluid (CSF), and sometimes increased intracerebral pressure also leads to hydrocephalus. Endoscopic Third Ventriculostomy (ETV) treatment is a new method for hydrocephaly treatment. In this method, in addition to the fact that the patient does not need an implant, the risk of infection is low and in the long term the result is...
BACKGROUND Temporary interruption of cerebral blood flow during carotid endarterectomy can be avoided by using a shunt across the clamped section of the carotid artery. This may improve outcome. This is an update of a Cochrane Review originally published in 1996 and previously updated in 2001. OBJECTIVES To assess the effect of routine versus selective, or never, shunting during carotid endar...
Background and purpose: Seizure in children with hydrocephalus is a common neurosurgical problem that may occur after shunting. This study aimed at comparing the preventive effect of phenytoin and levetiracetam in children with shunted hydrocephalus in a referral hospital. Materials and methods: All patients younger than 15 years of age who underwent ventriculoperitoneal (VP) shunt surgery for...
PURPOSE To evaluate magnetic resonance (MR) imaging-based quantitative phase-contrast cerebrospinal fluid (CSF) velocity imaging for prediction of successful shunting in patients with normal-pressure hydrocephalus (NPH). MATERIALS AND METHODS Eighteen patients (mean age, 73 years) with NPH underwent routine MR imaging and CSF velocity MR imaging before ventriculoperitoneal (VP) shunting. The ...
objective: the aim of this study was to find out the prevalence of protein energy malnutrition(pem) by anthropometric measurements in preschool children of tribal community of chhattisgarh. material and methods: a total of 449 children [237 boys and 212 girls] from 286 families were selected randomly. anthropometric measurements were done as per standard protocol. the level of underweight, stun...
