  1. 1. Stereotactic imaging in functional neurosurgery

    University dissertation from Umeå : Umeå University

    Author : Hidehiro Hirabayashi; Patric Blomstedt; Takaomi Taira; [2012]
    Keywords : 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

    University dissertation from Umeå : Umeå University

    Author : Ulrika Sandvik; Patric Blomstedt; Lars-Owe Koskinen; Stig Rehncrona; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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 Lesional surgery has largely been replaced by deep brain stimulation (DBS).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

    University dissertation from Institutionen för medicinsk teknik

    Author : Johannes Johansson; Karin Wårdel; Stefan Andersson-Engels; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosurgery; Radiofrequency ablation; Finite element method; Blood perfusion; Cerebrospinal fluid; Free convection; MEDICINE Surgery Surgical research Neurosurgery; MEDICIN Kirurgi Kirurgisk forskning 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. Energy Balance out of Balance after Severe Traumatic Brain Injury
