Primary vascular repair was performed in many cases. As to alleviate vascular occlusion, an interposition vein graft or venous bypass grafting were applied. However, one or more the internal diameters of applied vein graft are blocked or severely norrowed due to the kinking failure on saphenous vein graft. The objective of this study is to investigate the blood flow influence on vein graft with kinking failure. The 3-D computational fluid dynamic method was employed to determine velocity, pressure gradient, resistance of blood flow and wall shear stress on the kinked vein graft. We expect that velocity, pressure gradient, resistance of blood flow and wall shear stress on kinked vein graft to behave non-hydraulically compared to an ideal straight graft. Furthermore, a longitudinal impedence modulus (ZL) is expected to be insufficient due to kinking failure on vein graft. 2014-04-24T02:37:33Z 2014-04-24T02:37:33Z 2012 Article Procedia Engineering, vol. 41, 2012, pages 694-699 http://dspace.unimap.edu.my:80/dspace/handle/123456789/34005 http://dx.doi.org/10.1016/j.proeng.2012.07.231 http://www.sciencedirect.com/science/article/pii/S1877705812026318 en Elsevier Ltd. |
