An experimental study of ischemia following subcutaneous heterotopic intestinal graft: influence of arterial or venous occlusion.
A subcutaneously transferred intestinal model was prepared in the rat and experimental observations were conducted of serial histologic changes in the intestine and of acceptance rates, when the artery or vein in the pedicle was ligated at various times after transfer. Results showed 50 percent take in the artery-ligated group and 12.5 percent in the vein-ligated group, when performed 5 days after transfer; 87.5 percent take in the artery-ligated group and 50 percent in the vein-ligated group, when performed 7 days after transfer; and 100 percent take for both groups, when ligation was performed 14 days after transfer. Consequently, it was concluded that venous occlusion constitutes a greater danger to successful transfer of intestine than arterial occlusion.
