  1. 1. Evaluation of Intracranial Arteriovenous Malformations with Magnetic Resonance Imaging

    Författare :Maria Correia de Verdier; Johan Wikström; Elisabeth Ronne-Engström; Ljubisa Borota; Johan Wassélius; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arteriovenous malformation; brain; proton-radiation therapy; magnetic resonance imaging; phase-contrast MRI; Radiology; Radiologi;

    Sammanfattning : Intracranial arteriovenous malformations (AVMs) are characterized by feeding arteries, a tangle of abnormal vessels (nidus) and draining veins. Radiological evaluation methods are used in diagnosing AVMs, treatment planning, post-treatment evaluation and monitoring stability. LÄS MER

  3. 2. Gamma knife surgery of cerebral arteriovenous malformations

    Författare :Bengt Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Brain arteriovenous malformation; Radiosurgery; Natural course; Surgery; Risk; Complications; Prediction; Risk estimation formula; Radionecrosis;

    Sammanfattning : Aims of the study: to define and quantify parameters of importance for the treatment result in Gamma Knife (GK) surgery of arteriovenous malformations (AVM). To determine the natural course of AVM in order to calculate the impact of the GK treatment on the latency period between treatment and obliteration. LÄS MER

  4. 3. Surgically corrected univentricular hearts. Anatomical, haemodynamic and functional status at a long-term follow-up

    Författare :Eva Strömvall-Larsson; Göteborgs universitet; []
    Nyckelord :cavopulmonary connections; univentricular hearts; long-term follow-up; pulmonary; arteriovenous malformations; lung volumes; cardiac output; pulmonary gas exchange and maximal; exercise studies;

    Sammanfattning : The Fontan operation and its modifications are applied to a large spectrum of congenital heart defectswith univentricular physiology. The Fontan circulation is characterised by a reduced, non-pulsatilepulmonary blood flow and the elevated central venous pressure is the main driving force for thepulmonary blood flow. LÄS MER

  5. 4. Results and complications of endovascular neurointerventions in intracranial aneurysms and arteriovenous malformations, evaluated by conventional angiography and diffusion-perfusion MRI

    Författare :Mats Cronqvist; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endovascular treatment; medical instrumentation; tomography; radiology; Clinical physics; Medicin människa och djur ; Medicine human and vertebrates ; Diffusion and perfusion; Complications; Magnetic Resonance Imaging; Cerbrovascular malformations; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Aims - To describe and evaluate the efficacy and safety of intra-arterial fibrinolysis and the clinical outcome in SAH patients with thromboembolic complications during endovascular coiling of a ruptured aneurysm. (Paper I) - To describe the use and feasibility of magnetic resonance imaging (MRI), especially diffusion and perfusion imaging, in three patients treated endovascularly for various cerebrovascular disorders.

  7. 5. Hypofractionated conformal stereotactic radiotherapy in the treatment of AVMs and cerebral metastases

    Författare :Peter Lindvall; Hans Bolander; Umeå universitet; []
    Nyckelord :arteriovenous malformations; brain metastases; hypofractionation; stereotactic radiotherapy; LINAC; embolisation; Clinical Neurophysiology; klinisk neurofysiologi;

    Sammanfattning : Hypofractionated conformal stereotactic radiotherapy (HCSRT) has been used for the treatment of AVMs at the Umeå University Hospital since 1986. From this year and onwards an increasing number of patients with single or oligo brain metastases have also been treated using this technique. LÄS MER
