This is the case of two adult patients who presented with a low rectal carcinoma. A low anterior resection was performed laparoscopically. In both cases, the procedure was begun with a mobilization of the splenic flexure to ensure sufficient length on the proximal colonic segment to facilitate a tension-free low colorectal anastomosis. In the first case, a small aberrant artery, and during the second case, an aberrant artery of greater caliber can be appreciated. Anatomical studies report an extra central arterial connection between the superior and inferior mesenteric arterial systems in addition to the marginal artery of Drummond in 10 to 30% of cases. In such cases, there is an extra connection from the ascending branch of the left colic artery to the middle colic artery or the marginal artery of Drummond. Different names have been given to these connections, such as for example the meandering mesenteric artery, the artery of Moskovitch and Riolan’s arch.
