2. 6. Aortic infections : The Nadir of Vascular Surgery

   Author : Karl Sörelius; Anders Wanhainen; Kevin Mani; Björck Martin; Benjamin Ware Starnes; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mycotic; aortic; aneurysm; surgery; infection; endovascular repair; open abdomen; Kirurgi; Surgery;

   Abstract : Aortic infections are rare, life-threatening and constitute a major challenge in surgical management. This thesis aims to evaluate short – and long-term outcome of endovascular aortic repair (EVAR) for mycotic aortic aneurysms (MAA) and the subsequent risk of recurrent infections, changes in surgical practice over time for abdominal MAAs in Sweden and outcome for different treatment modalities, as well as the risk of secondary vascular infection after treatment with Open abdomen after aortic surgery.

4. 7. Engineering the shape of bacterial cellulose and its use as blood vessel replacement

   Author : Henrik Bäckdahl; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tissue engineering.; smooth muscle cells; bacterial cellulose; scaffold design; tubular fermentation; biocompatibility evaluation; Blood vessel; vascular graft;

   Abstract : Tissue loss and organ failure are major health problems that impose great costs on society. Cardiovascular diseases are responsible for 36% of mortalities and the disease burden among adults over the age of 60. The single largest cardiovascular disease is atherosclerosis in the coronary artery. READ MORE

5. 8. Aspects on Imaging and Endovascular Treatment of Aortic Dissection and Aneurysm

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

   Abstract : 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.

6. 9. Mechanisms and treatment options of chronic graft dysfunction : Experimental and clinical studies

   Author : Lilija Zezina; Uppsala universitet; []
   Keywords : Medical sciences; chronic graft dysfunction; kidney transplantation; aorta transplantation; lipid oxidation; LDL; TGF-beta; Smad2; angiotensin II receptor; treatment; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Abstract : Chronic graft dysfunction (CGD) is an important post-transplant complication. CGD can be considered as an impaired repair process, which ultimately leads to the loss of graft function.To study non-immunological factors contributing to the development of CGD in kidney grafts we used in vitro and in vivo models, and clinical studies.

7. 10. Decellularization as a method to generate a new generation of vascular grafts

   Author : Robin Simsa; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tissue engineering; vascular grafts; cardiovascular disease; decellularization;

   Abstract : Decellularization of blood vessels is a technique to remove cells from the extracellular matrix (ECM), which can be used as a vascular graft for peripheral or coronary blood vessel bypass surgery. This thesis focuses on the optimization of decellularization strategies for blood vessels such as porcine vena cava, to determine the optimal decellularization protocol (Paper I) and the ideal method of applying liquids during the decellularization process (Paper II).
