In this book, the authors present current research in the study of the risk factors, diagnosis, surgery and repair of aortic aneurysms. Topics discussed in this compilation are the genetic risk factors for abdominal aortic aneurysms (AAA); assessment of aortic aneurysm rupture risk and surgical repair; morphometric model of abdominal aortic aneurysm and the significance of the structural changes in the aortic wall for rupture risk assessment; the pathogenesis of abdominal aortic aneurysms; endovascular aneurysm repair in challenging anatomy; abdominal aortic aneurysm screening; aortic hemodynamics and their role in aneurysm location; decision-support system for diagnosis of abdominal aortic aneurysm after endovascular repair; and the clinical, hemodynamical and mechanical aspects of aortic aneurysms and endovascular repair.
