  2. 1. Stereotactic imaging in functional neurosurgery

    Author : Hidehiro Hirabayashi; Patric Blomstedt; Takaomi Taira; Umeå universitet; []
    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

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

    Author : Ulrika Sandvik; Patric Blomstedt; Lars-Owe Koskinen; Stig Rehncrona; Umeå universitet; []
    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 Lesional surgery has largely been replaced by deep brain stimulation (DBS).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

  5. 3. On optical methods for intracerebral measurements during stereotactic and functional neurosurgery : Experimental studies

    Author : Johan Antonsson; Karin Wårdell; Lars-Erik Augustinsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser Doppler perfusion monitoring; Diffuse reflectance spectroscopy; Functional and stereotactic neurosurgery; Medical engineering; Medicinsk teknik;

    Abstract : Radio frequency (RF) lesioning and deep brain stimulation (DBS) are the two prevailing surgical treatments for movement disorders within the field of stereotactic and functional neurosurgery. For RF-lesioning, a small volume of brain tissue is coagulated and knowledge of the lesion size and growth is of great importance for the safety and outcome of the procedure. READ MORE

  6. 4. Stereotactic microdialysis for metabolic assessment and experimental treatment of malignant glioma

    Author : Pedram Tabatabaei; A. Tommy Bergenheim; Mikael Johansson; Maria Zetterling; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain microdialysis; Glioblastoma multiforme; Malignant glioma; Retrograde microdialysis; Glucose metabolism; Radiotherapy; Chemotherapy; Cytokine.; neurokirurgi; Neurosurgery;

    Abstract : Glioblastoma multiforme, the most common primary brain tumor, has a dire prognosis despite multimodal treatments that include surgery and radio-chemotherapy. To improve the outcome of this destructive disease, we need to improve our understanding of its tumor biology. READ MORE

  7. 5. Characterisation of brain electrodes for ablative neurosurgery

    Author : Ola Eriksson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Stereotactic ablative neurosurgery with radio frequency current is regularly performed on patients with movement disorders, for instance Parkinson's disease. Even though the technique has been used for ablation in the brain for almost 50 years, nobody has suggested a standardised way of testing the electrodes used for ablative surgery. READ MORE
