چکیده
Abstract OBJECTIVES The actual underlying mechanisms of acute type A aortic dissection (AAAD) are not well understood. present study aimed to elucidate the mechanism AAAD using computational fluid dynamics (CFD) analysis. METHODS We performed CFD analysis patient-specific computed tomography imaging in 3 healthy control cases and patients with AAAD. From images, we made a model or pre-dissection for Pulsatile cardiac flow during one cycle was simulated, three-dimensional streamline visualized evaluate velocity, wall shear stress oscillatory index (OSI). RESULTS In controls, transvalvular parallel ascending aorta. There no spotty high OSI area at patients, accelerated towards posterolateral vortex observed on side lesser curvature mid-systole expanded throughout entire aorta diastole. Systolic due blood greater On curvature, areas were around flow. all cases, close proximity primary entry site future CONCLUSIONS pre-onset is closely associated site. Therefore, can

Endovascular repair of type B aortic dissection: a study by computational fluid dynamics
Aortic dissection is a dangerous pathological condition where blood intrudes into the layers of the arterial walls, creating an artificial channel (false lumen). In the absence of thrombosis or surgical intervention, blood will enter the false lumen through the proximal tear, and join the true lumen again through a distal tear. Rupture of the weakened outer wall will result in extremely high mo...
متن کاملa simple emergency prediction tool for acute aortic dissection.
a simple emergency risk prediction tool should be developed for clinicians to quickly identify the prognosis of patients with acute aortic dissection.we enrolled 280 patients with acute aortic dissection admitted to emergency department between may 2010 and february 2013. multivariate logistic regression analysis was performed to identify independent predictors of in-hospital death.the in-hospi...
متن کاملInvestigation of handmade ferrofluids' motion in a ventilated cavity using computational fluid dynamics
In this research, some more applicable ferrofluids are produced and their mechanical specifications are measured, experimentally. Also, their treatments in the ventilated cavity geometry are assessed numerically. The magnetite nanoparticles are produced by a chemical combination of Fe2+ and Fe3+ with NH3. In order to solve the nanoparticles in the new mediums, a...
