  1. 1. Stereotactic imaging in functional neurosurgery

    Author : Hidehiro Hirabayashi; Patric Blomstedt; Takaomi Taira; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Deep brain stimulation; pallidotomy; thalamotomy; Parkinson s disease; essential tremor; CT; MRI; neurokirurgi; Neurosurgery;

    Abstract : Background: The birth of stereotactic functional neurosurgery in 1947 was to a great extent dependent on the development of ventriculography. The last decades have witnessed a renaissance of functional stereotactic neurosurgery in the treatment of patients with movement disorders. READ MORE

  2. 2. Stereotactic functional procedures in the treatment of essential tremor

    Author : Ulrika Sandvik; Patric Blomstedt; Lars-Owe Koskinen; Stig Rehncrona; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Essential Tremor; Stereotactic Functional Neurosurgery; Deep Brain Stimulation; Posterior Subthalamic Area; Thalamotomy; Zona incerta; caudal Zona incerta; Quality of Life; Vim; neurokirurgi; Neurosurgery;

    Abstract : Background: Essential tremor (ET) is the most common movement disorder. In cases resistant to pharmacological treatment, functional stereotactic neurosurgery can be an alternative. Lesional surgery has largely been replaced by deep brain stimulation (DBS). The current target of choice is the ventrolateral thalamus (Vim). READ MORE

  3. 3. Thermocoagulation in Deep Brain Structures : Modelling, simulation and experimental study of radio-frequency lesioning

    Author : Johannes Johansson; Karin Wårdel; Stefan Andersson-Engels; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosurgery; Radiofrequency ablation; Finite element method; Blood perfusion; Cerebrospinal fluid; Free convection; Neurosurgery; Neurokirurgi;

    Abstract : Radio-frequency (RF) lesioning is a method utilising high frequency currents for thermal coagulation of pathological tissue or signal pathways. The current is delivered from an electrode with a temperature sensor, permitting control of the current at a desired target temperature. In the brain RF-lesioning can e.g. READ MORE

  4. 4. Pressure autoregulation of cerebral blood flow in traumatic brain injury and aneurysmal subarachnoid hemorrhage

    Author : Ulf Johnson; Per Enblad; Lars-Owe Koskinen; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral blood flow; autoregulation; traumatic brain injury; subarachnoid hemorrhage; Neurosurgery; Neurokirurgi;

    Abstract : The ability of the brain to keep a stable and adequate cerebral blood flow (CBF) independently of fluctuations in systemic blood pressure is referred to as cerebral pressure autoregulation (CPA). When the brain is injured by trauma or hemorrhage, this ability may be impaired, leaving the brain vulnerable to events of high or low blood pressure. READ MORE

  5. 5. Population-based studies of brain tumor surgery: surgical outcome and prognostic factors

    Author : Alba Corell; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosurgery; Glioma; Meningioma; Population-based;

    Abstract : Neurosurgery is the cornerstone in the treatment of a majority of brain tumors. Surgery can sometimes cure or delay tumor progression. However, surgery is associated with risks, and adequate information about the anticipated peri- and postoperative course is important for informed consent. READ MORE
