Abstract
- The hemodynamic characteristics of the cuff end-to-side anastomosis model are investigated using by the finite volume predictions. The flow rates and the impedance indices through of the cuff anastomosis model are compared with those of the anastomosis model without the cuff. Blood flow increased through the cuff anastomosis model than the standard anastomosis model. The impedance index decreased with the increase of flow rate. The impedance index at a given flow rate is reduced by the increase of anastomosis angle and further reduced by the addition of the cuff. The results suggest that the cuff anastomosis model should be applied for the low Reynolds number flow and/or the small artery anastomosis model.
