 note = {Occlusion after reconstructive vascular surgery in the peripheral vessels is supposed to be caused by thrombus formation due to hemodynamic changes at anastomotic sites. Flow patterns which are changed at anastomotic sites due to alteration of vascular lumen or flow course are observed in this study. Since vascular anastomotic site easily fell into constriction, special attention was given to flow through stenotic orifices and through branched tubes for a study of bypass graft in this study. The mixture of glycerin and water was made to have approximately the same viscosity and specific gravity as the blood. Fine aluminum powder was added to this mixture in order to demonstrate flow lines. The solution was made to run in glass tubes which modify vascular stenosis and bypass graft. Slide projectors were used to pass the light through a slit properly focused upon the flow, the flow field could be visualized and flow patterns were observed. Eddy and stagnation zones were formed in the marginal areas of the poststenotic regions and at the junction of bifurcation in the main tube in which flow was not running. The glass models were attached extracorporeally to the canine abdominal aorta to observe the sites of thrombus formation. Thrombus was prominently attached in the areas of stagnation and eddy currents as observed above. The experiments brought about a result that vascular reconstruction should be made without stenosis and the space of non-flowing at bypass graft.},
