Summary:The present study aims to clarify the blood flow in a blood vessel perfused from a cannula during cardiac surgery with extracorporeal circulation. Figure shows the calculations of velocity profile in an aortic arch by STAR-CD. The three-dimensional calculation model of an aortic arch was made by Mimics using several hundred CT images. After the flow perfused from a cannula firstly impinges on the lesser curvature wall of an aortic arch, it flows along the wall. Then the flow leaves the lesser curvature wall and impinges on the greater curvature wall. The flow separates into right and left directions and generates vortices right and left sides of the impingement point.
