Abstract
In our study, we made realistic model of aneurysm and analyzed precise flow profile in patients' aneurysms. A clear acrylic internal calotid artery (ICA) lateral aneurysm model was made by using 3D CT angiogram and flow profile during one cardiac cycle in aneurysm was analyzed. Flow profile within the aneurysm model were obtained from velocity measurements by using laser Doppler velocimetry and Particle Image velocimetry. The flow from the parent artery was divided into the daughter artery and the aneurysm along proximal side of the neck. The inflow zoon changed dynamically in cross section of the neck. The highest shear stress was marked at the neck of the aneurysm. The result can show that the characteristic flow change gives controversy relating to coiling.
