  1. 1. Arterial mechanics : noninvasive identification of constitutive parameters and residual stress

    Författare :Jonas Stålhand; Gerhard A. Holzapfel; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis concerns the mechanical modelling of arteries, and particularly a method to identify parameters describing the mechanical properties using only clinically obtainable in vivo measurements. The artery is modelled as a fibre reinforced, incompressible, thick-walled cylinder subjected to large deformations and a residual stress field. LÄS MER

  3. 2. Ultrasonic Methods for 2D Arterial Wall Movement Measurements

    Författare :Magnus Cinthio; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue Doppler imaging; Cardiovascular system; Diagnostik; Diagnostics; Kardiovaskulära systemet; arteries; ultrasound; shear stress; axial movement; radial movement; Arterial distension; Arterial lumen diameter; PWV; Arterial longitudinal movement; pulse-wave velocity;

    Sammanfattning : Cardiovascular diseases constitute the major cause of morbidity and mortality in the Western World. To increase our knowledge of cardiovascular diseases, it is important to find methods, preferably non-invasive ones, to study very early manifestations of vascular disease. LÄS MER

  5. 4. The impact of duplex scanning in the management of chronic lower limb arterial disease

    Författare :Annika Boström Ardin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Duplex; Ultrasound; lower extremity; arterial; chronic ishemia; selection; surgery; PTA; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : In patients with chronic lower extremity ischemia in which endovascular or surgical intervention is considered non-invasive evaluation by duplex scanning provides important anatomical and hemodynamic information. The aim of this thesis was to evaluate the impact of duplex scanning in the selection of various therapeutic alternatives in limbs with lower extremity arterial insufficiency. LÄS MER

  7. 5. The inflammatory response to arterial injury

    Författare :Paul Dimayuga; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; neointima; arterial injury; inflammation; Kardiovaskulära systemet;

    Sammanfattning : Atherosclerosis as a disease is postulated to stem from a response to injury of the arterial wall by various stimuli. The inflammatory response is proposed to mediate intimal formation after injury. One pathway of cellular response to injury is through transcription factor NF-kB. LÄS MER
