  2. 16. Treatment of abdominal and thoracic aortic aneurysms :  Aspects on epidemiology and surgical outcome

    Author : Kim Gunnarsson; Kevin Mani; Jonas Eiberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic aneurysm. Ruptured aortic aneurysm; Endovascular aneurysm repair; Open aortic repair; Aneurysm; Outcome; Surgery; Kirurgi;

    Abstract : Aortic Aneurysm (AA) is a life-threatening condition when ruptured (RAA), requiring immediate repair for survival. Since the 50´s, open repair, replacing the diseased vessel with a prosthetic (synthetic) graft, has been the gold standard. READ MORE

  4. 17. Abdominal compartment syndrome and colonic ischaemia after abdominal aortic aneurysm repair in the endovascular era

    Author : Samuel Ersryd; Anders Wanhainen; Martin Björck; Khatereh Djavani; Anders Albäck; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic aneurysm-abdominal; Intra-abdominal pressure; Intra-abdominal hypertension; Abdominal compartment syndrome; Rupture; Open ab-domen treatment; Colonic ischaemia; Endovascular aneurysm repair; Surgery; Kirurgi;

    Abstract : Abdominal Compartment Syndrome (ACS) and colonic ischaemia (CI) are serious and potentially lethal complications after open (OSR) and endovascular repair (EVAR) of ruptured (rAAA) and intact (iAAA) abdominal aortic aneurysms. The aims of this thesis were to investigate the incidence, outcome, and risk factors associated with ACS (Papers I-III) and to evaluate extraluminal colonic tonometry for postoperative surveillance of colonic perfusion (Paper IV).

  5. 18. Copula-based Portfolio Optimization

    Author : Maziar Sahamkhadam; Andreas Stephan; Håkan Locking; Ranadeva Jayasekera; Linnéuniversitetet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Copula; portfolio optimization; conditional Value-at-Risk; vine copulas; asymmetric tail dependence; Black-Litterman approach; expectile Value-at-Risk; multiobjective portfolios; Business administration; Företagsekonomi;

    Abstract : This thesis studies and develops copula-based portfolio optimization. The overall purpose is to clarify the effects of copula modeling for portfolio allocation andsuggest novel approaches for copula-based optimization. The thesis is a compilation of five papers. READ MORE

  6. 19. Tomographic methods in endovascular aortoiliac treatment

    Author : Per Törnqvist; Vaskulära sjukdomar - kliniska studier; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Endovascular treatment had developed rapidly and the procedures have increased in complexity. The demand of imaging excellence is imperative to perform these interventions. However both pre and postoperative investigations are performed by the use of advanced three-dimensional imaging, while the treatment itself relies on two-dimensional imaging. READ MORE

  7. 20. Juxtarenal aortic aneurysm - Endovascular treatment and imaging techniques

    Author : Thorarinn Kristmundsson; Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Abdominal aortic aneurysm; juxtarenal aneurysm; endovascular repair; fenestrated endovascular repair; imaging; computed tomography; ultrasound.;

    Abstract : Treatment of abdominal aortic aneurysms has shifted rapidly from open surgery to minimally invasive endovascular aneurysm repair (EVAR). However, anatomical limitations such as short or absent proximal sealing neck and poor access vessels exclude up to 50% of patients. READ MORE
