OBJECTIVE A Sylvian fissure arachnoid cyst (SAC) is a well-recognized location for an intracranial arachnoid cyst in the pediatric population. For those cysts, which can rupture and be accompanied by a subdural hygroma or hematoma, several treatment modalities have been reported. We report clinical and radiological outcome of fenestration of these cysts by(More)
Anti-siphon devices (ASDs) of various working principles were developed to overcome overdrainage-related complications associated with ventriculoperitoneal shunting. We aimed to provide comparative data on the pressure and flow characteristics of six different types of ASDs (gravity-assisted, membrane-controlled, and flow-regulated) in order to achieve a(More)
Myelomeningocele is one of the major congenital malformations involving the central nervous system. It is caused by a disruption of the neural tube closure, which is completed at 3–4 weeks of gestation. Multidisciplinary approach is necessary to treat and support this malformation which is a huge burden to the patient, family, and the society. This is a(More)
Anti-siphon devices and gravitational-assisted valves have been introduced to counteract the effects of overdrainage after implantation of a shunt system. The study examined the flow performance of two gravitational-assisted valves (shunt assistant – SA and programmable shunt assistant – proSA, Miethke & Co. KG, Potsdam, Germany) in an in vitro shunt(More)
We have diagnosed 35 cases of the supposedly rare condition metopic-sagittal synostosis in the past 20 years. Here, we introduce their clinical symptoms, neuroradiological findings, and surgical treatment methods, as well as discuss the relevant literature. Subjects included 35 patients (33 boys and 2 girls; mean age 4.2 years; range 1–8 years). Magnetic(More)
