  1. 11. Endovascular Repair of Abdominal Aortic Aneurysms. Aspects on a Novel Technique

    Författare :Martin Malina; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; migration.; endoleak; stent; stentgraft; endovascular repair; Aneurysm; therapy; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : A new concept of treating abdominal aortic aneurysms was studied during a three-year period. Instead of open repair, graft insertion was accomplished endovascularly from the groins. The graft was attached by expandable stents to the non-dilated infrarenal aorta, i.e. LÄS MER

  3. 12. Anterior cruciate ligament reconstruction : patellar tendon, Gore-Tex, Kennedy LAD and tibia tunnel ingrowth

    Författare :Olle Muren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Prospective studies; randomized controlled trials; anterior cruciate ligament; treatment outcome; osteoarthritis; knee; prostheses and implant; radiology; reconstructive surgical procedures.;

    Sammanfattning : Anterior cruciate ligament injury can induce permanent functional impairment in the physically active individual. Different methods to repair or replace the tom ligament have been tried and investigated. This thesis investigates three principally different grafts used in ACL reconstruction; autogenous tendon, stent/augmentation and prosthetic. LÄS MER

  4. 13. Size Characterisation of Water-Soluble Polymers Using Asymmetrical Flow Field-Flow Fractionation

    Författare :Bengt Wittgren; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multi-angle light scattering; molar mass distribution; aggregation; size characterisation; Asymmetrical flow FFF; water-soluble polymers; polysaccharides; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Size, as expressed by molar mass, radius of gyration or hydrodynamic radius, for example, is a fundamental parameter of polymers in solution. Thus, there is a strong need for the characterisation of both the size and shape of polymers, particularly of those utilised in various industrial applications. LÄS MER

  5. 14. Popliteal Artery Aneurysms : - epidemiology, treatment and results

    Författare :Anne Cervin; Martin Björck; Mårten Falkenberg; Hans Ravn; Michelle Antonello; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Popliteal artery aneurysms; Endovascular; Open surgery; Outcome; Occlusion; Screening; Prevalence; Rupture; Surgery; Kirurgi;

    Sammanfattning : Popliteal aneurysms (PA) are limb threatening, since the aneurysm thrombose and emboli from the aneurysm sac occlude the distal vessels, resulting in chronic or acute limb ischaemia. Open surgical repair (OSR) has been challenged by endovascular repair (ER), a minimal invasive technique. LÄS MER

  7. 15. On tissue reactions to dentin as a bone substitute material

    Författare :Payam Farzad; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Grafted dentin; tissue reaction; bone blocks; dental implants; experimental study;

    Sammanfattning : Background Reconstruction of the jaws due to resorption of the alveolar crest may require bone augmentation prior to installation of endosseous implants. Active research on new bone graft materials with bone regeneration ability equivalent to autogenous bone but without the limitations of allogenic, xenogenic and synthetic bone are constantly ongoing.
