| Abstract | ||
| The normal arterial vasculature of the descending colon of 15 native breed dogs was anatomically studied after injection with gum milk (Latex) and radioopaque substance. The left colic artery of the caudal mesenteric artery is distributed within the colon in superficial or deep manner. The colic twigs of the superficial branches are distributed under the serosa parallel to the longitudinal muscular layer while that of the deep colic branches are distributed under the muscular layer of the colon. Experimental resection of 4 cm and 6 cm from the descending colon was carried out on 20 native breed dogs in order to evaluate the influ ence of segmental colonic resection on the arterial vasculature of that part. After resection, the area of operation which lies cranial to the origin of caudal mesenteric artery is supplied by side branches from the left and middle colic arteries. The degree of anastomotic healing was assessed on radiological examination through angiography of the part of colon in addition to the barium enema. | ||
