  1. 21. Large cerebral artery occlusion and recanalisation in stroke patients treated with intravenous thrombolysis : clinical and radiological markers and their clinical relevance

    Författare :Tatiana Kharitonova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Large cerebral artery occlusion accounts for 40-46% of ischemic strokes. These strokes are characterized by extensive neurological deficit, poor functional outcome, and increased mortality (up to 40-80% in the most severe clinical syndromes). LÄS MER

  3. 22. Intravenous contrast media optimization at computed tomography

    Författare :Anders Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The administration of intravenous contrast media (IV CM) is essential for detecting lesions at most computed tomography (CT) examinations. The overall aim of this thesis is to investigate different aspects of IV CM administration that may affect the quality of the CT examination. LÄS MER

  4. 23. Aspects on Imaging and Endovascular Treatment of Aortic Dissection and Aneurysm

    Författare :Mats-Ola Eriksson; Rickard Nyman; Anders Wanhainen; Johnny Steuer; Mårten Falkenberg; Uppsala universitet; []
    Nyckelord :Aneurysms; aorta; stents; ultrasound; colour Doppler; vascular; interventional; aortic dissection; complicated; TEVAR; EVAR; re-intervention; survival; thrombosis; false lumen; aortic remodelling; Radiology; Radiologi;

    Sammanfattning : Aortic aneurysm and dissections are potentially life threatening conditions. The advent of endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR) has reduced perioperative mortality and morbidity and are now established therapy methods for treatment of aortic disease.

  5. 24. Three-dimensional guidance for Endovascular Aortic Repair

    Författare :Giasemi Koutouzi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anatomy deformation; CBCT; EVAR; image fusion; image guidance; image registration;

    Sammanfattning : Image fusion (IF) of preoperative computed tomography (CT) with intraoperative cone-beam CT (CBCT) is a potentially powerful tool for guidance during endovascular aortic repair (EVAR). It may improve intraoperative anatomic visualization and reduce doses of radiation and contrast medium. LÄS MER

  7. 25. Biomechanics of abdominal aortic aneurysm:Experimental evidence and multiscale constitutive modeling

    Författare :Giampaolo Martufi; T. Christian Gasser; Tim McGloughlinm; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The reliable assessment of Abdominal Aortic Aneurysm (AAA) rupture risk is critically important in reducing related mortality without unnecessarily increasing the rate of elective repair. A multi-disciplinary approach including vascular biomechanics and constitutive modeling is needed to better understand and more effectively treat these diseases. LÄS MER
