  2. 11. 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

  4. 12. 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

  5. 13. Pathogenesis of infections related to foreign devices within the cerebral ventricles

    Author : Fredrik Lundberg; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; Microbiology; CSF-shunt; complement activation; vitronectin; hydrocephalus; coagulase-negative staphylococci; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Coagulase-negative staphyloccoci (CoNS) are the most frequently isolated micro-organisms from infected cerebrospinal fluid (CSF) shunts and temporary ventricular drainage catheters, used in modern neurosurgery. CoNS originate from the skinflora of the patient or the surgeon and gain access to the surface of the implant at the insertion, but the infection can erupt up to a year later or more. READ MORE

  6. 14. On the pathophysiology of idiopathic adult hydrosephalus syndrome : energy metabolism, protein patterns, and intracranial pressure

    Author : Aina Ågren Wilsson; Per Enblad; Umeå universitet; []
    Keywords : hydrocephalus; biochemical markers; microdialysis; cerebrospinal fluid; B waves; brain tissue oxygen tension; Neurology; neurologi;

    Abstract : The symptoms in Idiopathic Adult Hydrocephalus Syndrome (IAHS) – gait disturbance, incontinence, and cognitive deficit – correlate anatomically to neuronal dysfunction in periventricular white matter. The pathophysiology is considered to include a cerebrospinal fluid (CSF) hydrodynamic disturbance, including pressure oscillations (“B waves”), in combination with cerebrovascular disease. READ MORE
