Introduction: based on embryology right and left colon can be distinguished according to whether it’s vascularized by the superior or inferior mesenteric artery respectively. In its classic description, middle colic artery arises from the superior mesenteric artery, and supplies the transverse colon. Left superior colic artery usually originates from the inferior mesenteric artery. Case report: we describe an anatomical variation in which middle colic artery directly irrigates de left colon. It was found during the dissection of a female cadaver fixed in formalin solution, in the Medicine Faculty of the University of the Republic. Middle colic artery was identified from its usual origin, and had a variation of its course, descending at the left flank of the abdominal aorta, and giving rise to the left colic artery. Distally it participated in the rectum supply. Discussion: anatomical variations of the left colon vascularization has been said to be less frequent than those of the right colon. In this case a branch of the superior mesenteric artery supply the left colon. These can not only implicate possible complications during colon surgery, but also sets an interrogant whether which would be the best oncologic solution in such cases for a left colon tumor. Importance of anatomical knowledge of left colon vascularization and its variations, remains important and has implicances in surgical practice.
