Esophageal Reconstruction

The colon is supplied with arterial blood from two main sources: the superior mesenteric artery (arteria mesenterica superior) and the inferior mesenteric artery (arteria mesenterica inferior). The right colon is supplied from the superior mesenteric artery through the following arteries: ileocolic artery (arteria ileo-colica), right colic artery (arteria colica dextra) and middle colic artery (arteria colica media). The inferior mesenteric artery supplies arterial blood to the left colon through the left colic artery (arteria colica sinistra). The ascending branch of the left colic artery (ramus ascendens) is joined with the middle colic artery by the arc of Riolan, creating in this way a connection between branches of inferior and superior mesenteric artery ( Fig. 1, 2).
