  1. 1. Biomechanics of AAA surveillance patients

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Murtaza Rafi; [2019]
    Keywords : ;

    Abstract : Abdominal aortic aneurysms (AAA) occurs due to local enlargement of the abdominal aorta and affects about 1-2 % of the elderly Swedish population. At admission, AAA patients receive a Computed Tomography-Angiography (CT-A) scanning, and later they are followed-up by 2D ultrasound examinations. READ MORE

  3. 2. Multimaterial 3D Printing of a mechanically representative aortic model for the testing of novel biomedical implants

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sudhanshu Kuthe; [2019]
    Keywords : 3D printing; Aortic model; Composite design; Stiffness; Bio-material;

    Abstract : Aortic stenosis is a serious cardiovascular disease that requires urgent attention and surgical intervention. If not treated, aortic stenosis can result in heart attack or cardiac arrest. Transcatheter Aortic Valve Replacement is a surgical technique that is used to treat aortic stenosis. READ MORE

  4. 3. Influence of inflow conditions on simulations of arterial blood flow

    University essay from KTH/Mekanik

    Author : Marcus Strimell Flodkvist; [2018]
    Keywords : ;

    Abstract : The blood is responsible for the oxygenation of the body and to carry nutrients to the different parts of the body and waste products away from the major organs like the liver, kidneys but also the walls of the arteries. Blood is composed of red blood cells that are on average 45% of the total volume, the rest of the blood is made up of blood plasma platelets, white blood cells, minerals and nutrients. READ MORE

  5. 4. Visualization and Quantification of Helical Flow in the Aorta using 4D Flow MRI

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Filippa Gustafsson; [2016]
    Keywords : Helical flow; Helicity density; LNH; 4D Flow MRI; geometry of the aorta;

    Abstract : Due to the complex anatomy of the heart, heart valves and aorta, blood flow in the aorta is known to be complex and can exhibit a swirling, or helical, flow pattern. The purpose of this thesis is to implement methods to quantify and visualize both the speed of helicity, referred to as the helicity density, and the direction of helicity, which is measured by the localized normalized helicity.

  6. 5. Optimizing numerical Aneurism growth predications.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Gustav Thorén; [2015]
    Keywords : ;

    Abstract : Abdominal Aortic aneurysm (AAA) is a localized dilation of the abdominal aorta exceeding the normal diameter by more than 50 %. A common complication is rupture of the vessel wall, which in most cases is life-threatening. READ MORE
