Three-Dimensional Flow in an End-to-Side Vascular Anastomosis: Steady and Pulsatile Flow

End-to-Side 혈관문합에서의 삼차원유동: 정상유동 및 맥류유동

Three-dimensional steady and pulsatile flows in an end-to-side anastomosis were investigated using a finite difference method in order to understand the flow dynamics in the preferential development of distal anastomotic intimal hyperplasia or thrombosis. Steady flow results revealed that a double helical vortex was formed in the host artery and flow recirculations near tow and heel regions were limited due to the secondary flow. Oscillating wall shear stress with significant secondary flow might be the flow dynamic reason of developing intimal hyperplasia or thrombosis.
