2. 1. Cerebrospinal Fluid Shunts in Children : Technical Considerations and Treatment of Certain Complications

   Author : Kai Arnell; Tomas Wester; Jan Sjölin; Per Enblad; Hans C-son Silander; Uppsala universitet; []
   Keywords : Surgery; Hydrocephalus; papilloedema; abdominal cyst; cerebrospinal fluid shunt; shunt infection; intraventricular antibiotic instillation; intraventricular antibiotic concentrations; in-vitro testing; antisiphon device; Kirurgi;

   Abstract : Ventriculo-peritoneal shunting is the most commonly used method for the treatment of paediatric hydrocephalus. Despite improved shunts and surgical techniques there are still complications. This retrospective study focuses on diagnoses and treatment of shunt malfunction and infections. Cost/benefit of using an adjustable shunt was assessed. READ MORE

4. 2. Clinical evaluation of an adjustable cerebrospinal fluid shunt valve

   Author : Göran Zemack; Neurokirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Surgery; Cost analysis; Codman Hakim programmable valve; Pressure adjustable shunt valve; Cerebrospinal fluid shunt; Idiopathic intracranial hypertension; Hydrocephalus; Arachnoid cyst;

   Abstract : Introduction: Shunting systems are implanted for draining cerebrospinal fluid to treat hydrocephalus, intracranial cysts, and idiopathic intracranial hypertension. Most shunt systems include a valve which regulates drainage. A differential pressure valve opens when intracranial pressure exceeds the valve’s opening pressure. READ MORE

5. 3. The search for reversibility of Idiopathic normal pressure hydrocephalus : Aspects on intracranial pressure measurments and CSF volume alteration

   Author : Niklas Lenfeldt; Jan Malm; Anders Eklund; Katrine Riklund-Åhlström; John D. Pickard; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Idiopathic normal pressure hydrocephalus; intracranial pressure; subcortical ischemia; neuronal integrity; cortical activation.; infusion test; cerebrospinal fluid dynamics; outflow resistance; compliance; elastance; proton spectroscopy; functional MRI; external lumbar drainage; Neurology; Neurologi;

   Abstract : BACKGROUND: Idiopathic normal pressure hydrocephalus (INPH) is still a syndrome generating more questions than answers. Today, research focuses mainly on two areas: understanding the pathophysiology – especially how the malfunctioning CSF system affects the brain parenchyma – and finding better methods to select patients benefiting from a shunt operation.

6. 4. Cerebral blood flow and intracranial pulsatility studied with MRI : measurement, physiological and pathophysiological aspects

   Author : Anders Wåhlin; Anders Eklund; Jan Malm; Richard Birgander; William G Bradley; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arterial Pulsatility; cerebrospinal fluid; cerebral blood flow; venous flow; intracranial pressure; pulse pressure; dementia; hippocampus; multiple sclerosis; magnetic resonance imaging; radiofysik; radiation physics;

   Abstract : During each cardiac cycle pulsatile arterial blood inflates the vascular bed of the brain, forcing cerebrospinal fluid (CSF) and venous blood out of the cranium. Excessive arterial pulsatility may be part of a harmful mechanism causing cognitive decline among elderly. READ MORE
