Trauma and hemorrhage often require ligation of arteries supplying the tongue. The right common carotid artery was ligated in twenty-five rabbits. These animals were sacrificed at intervals and their vasculature perfused with a silicone latex material. Animals sacrificed one hour after ligation showed a greatly reduced blood flow to the right side of the tongue. Only a slightly reduced flow was observed in animals sacrificed at the six hour and twenty-four intervals. Animals in the one and two week groups displayed a microvascular perfusion pattern similar to that of the control animals which underwent no ligation. Author
