  1. 16. Medin amyloid - a matter close to the heart : Studies on medin amyloid formation and involvement in aortic pathology

    Författare :Annika Larsson; Per Westermark; Sari Kiuru-Enari; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AA amyloidosis; aging; amyloid; aneurysm; arterial media; dissection; elastin; medin amyloid; lactadherin; thoracic aorta; Pathology; Patologi;

    Sammanfattning : Amyloidoses are a group of protein misfolding diseases characterized by deposits of insoluble fibrillar protein aggregates. Medin amyloid, which is the focus of this thesis, appears in the media of the thoracic aorta in nearly all individuals over 50 years. LÄS MER

  3. 17. Familial thoracic aortic aneurysms and dissections : studies on genotype and phenotype

    Författare :Matias Hannuksela; Bo Carlberg; Bengt Johansson; Eva-Lena Stattin; Anders Gottsäter; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thoracic aorta; familial aortic aneurysm; familial aortic dissection; genetics; aortic stiffness;

    Sammanfattning : Background: Thoracic aortic aneurysms and dissections (TAAD) have a genetic component with an estimated 20-25% of the patients having a positive family history. An aneurysm often precedes a dissection. Acute aortic dissections are associated with high mortality and morbidity, even when operated on. LÄS MER

  4. 18. Estimating patient specific wall shear stress in the human aorta : geometrical and post-processing considerations

    Författare :Johan Renner; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis describes a workflow to perform in-vivo wall shear stress (WSS) estimations in the human aorta using computational fluid dynamics (CFD) methods. An abnormal WSS distribution is believed to influence the development of many cardiovascular diseases, e.g. atherosclerosis. LÄS MER

  5. 19. Aspects of subaneurysmal aortas in a screening setting

    Författare :Knut Thorbjørnsen; Anders Wanhainen; Sverker Svensjö; Khatereh Djavani Gidlund; Håkan Pärsson; Uppsala universitet; []
    Nyckelord :Abdominal aortic aneurysm; subaneurysmal aorta; screening; health related quality of life; health utility; quality adjusted life years; Kirurgi; Surgery;

    Sammanfattning : With the introduction of screening programmes for abdominal aortic aneurysm (AAA) more individuals are being identified with a subaneurymal aorta (SAA; diameter 25-29mm). More recent data indicate that these aortas may not be as harmless as previously thought, but there is, however, no general agreement on how SAA should be managed. LÄS MER

  7. 20. Modeling of Intraluminal Surfaces of Thoracic Aortas

    Författare :Johan Bondesson; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aneurysm; TEVAR; bird-beaking; cardiac pulsatility; geometric modeling; surface curvature; endograft; stereolithographic surface; dissection; Thoracic aorta;

    Sammanfattning : Vascular diseases are getting more and more common as a result of modern-day lifestyle and the fact that the population is getting older. One of the newest treatments for vascular diseases such as aneurysms and dissections is endovascular repair with endografting. LÄS MER
