1. 1. Abdominal aortic aneurysm inception and evolution - A computational model

   Författare :Andrii Grytsan; T. Christian Gasser; Martin Kroon; Frans N. van de Vosse; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aorta; Aneurysm; AAA; Blood Flow; Wall Shear Stress; Growth and Remodeling; Mixture Model; Growth Kinematics; Fluid-Solid-Growth; Aorta; Aneurysm; AAA; Blodflöde; Vägg Skjuvspänning; Tillväxt och Strukturförändring; Blandning Modell; Tillväxt Kinematik; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Abdominal aortic aneurysm (AAA) is characterized by a bulge in the abdominal aorta. AAA development is mostly asymptomatic, but such a bulge may suddenly rupture, which is associated with a high mortality rate. Unfortunately, there is no medication that can prevent AAA from expanding or rupturing. LÄS MER

3. 2. Aspects on Imaging and Endovascular Treatment of Aortic Dissection and Aneurysm

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

   Sammanfattning : 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.

4. 3. Volume imaging of the abdomen : three-dimensional visualisation of tubular structures in the body with CT and MRI

   Författare :Anders Persson; Örjan Smedby; Håkan Ahlström; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The overwhelming amount of image-based information in modem medicine makes it crucial to develop methods to handle and analyze images and make them comprehensible for users. The aim of this thesis was to study the radiological practice of three-dimensional (3D) visualization of tubular structures in the body with CT and MRI. LÄS MER

5. 4. Assessment of predicting blood flow and atherosclerosis in the aorta and renal arteries

   Författare :Alexander Fuchs; Lisa Prahl Wittberg; Örjan Smedby; Chunliang Wang; Anders Persson; Elazer Edelman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blodflödessimulering; Åderförkalkning; Väggskjuvspänning; Blodrehologiska modeller; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Cardiovascular diseases (CVD) are the most common cause of death in large parts of the world. Atherosclerosis (AS) has a major part in most CVDs. AS is a slowly developingdisease which is dependent on multiple factors such as genetics and life style (food, smoking, and physical activities). LÄS MER

7. 5. Atherosclerosis of the ascending aorta as a risk factor for stroke after cardiac surgery : a study based on epiaortic ultrasound

   Författare :Per Bergman; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cardiac surgery; atherosclerosis; ascending aorta; stroke; epiaortic ultrasound; intra-aortic filter.;

   Sammanfattning : Postoperative stroke is a dreaded problem in cardiac surgery and atherosclerosis of the ascending aorta (AAA) is an important risk factor. The risk from calcified AAA, the extent and the topography of the disease in the development of stroke was evaluated. LÄS MER
