   Sammanfattning : The pain-system is a central mechanism in our life. Chronic pain is one of the major causes of impaired health-related quality of life according to the World Health Organization’s “Global Burden of Disease”-studies. Zygapophysial joint pain has been shown to account for the pain in 30% - 50% of patients with chronic pain. LÄS MER

3. 2. Catheter Ablation of Atrial Fibrillation and Atrial Flutter : A Comparison of Cryo and Radiofrequency Techniques

   Författare :Helena Malmborg; Carina Blomström-Lundqvist; Stefan Lönnerholm; Pekka Raatikainen; Uppsala universitet; []
   Nyckelord :;

   Sammanfattning : Atrial fibrillation (AF) and atrial flutter (AFl) are two of the most common arrhythmias encountered in the population. Catheter ablation has emerged as a useful tool in the treatment of these arrhythmias. Although radiofrequency (RF) is the most commonly used energy source for ablation, cryoenergy may have some advantageous properties. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

5. 4. Stereotactic imaging in functional neurosurgery

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

   Sammanfattning : 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. LÄS MER
