Figure 3: Embryology of normal vascular anatomy and variant celiac-SMA trunk. In the primitive vasculature, (a) the 10th to 13th vitelline arteries connect the aorta with a ventral longitudinal anastomosis. In a normal anatomy, (b) the 10th and 13th persist to invidually form the celiac axis and superior mesenteric artery; the remaining segments regress before birth. If the 10th to 12th vitelline arteries regress but there is abnormal persistence of ventral anastomosis, a celiacomesenteric trunk occurs (c).
