From: Spontaneous dissection of celiacomesenteric trunk with isolated extension and thrombosis in the superior mesenteric artery: a case report and literature review

Fig. 5

Schematic diagram showing normal embryology and anatomy of the mesenteric vasculature and variant celiac-SMA common trunk. Normally, the 10th and 13th vitelline arteries persist to individually form the celiac trunk and SMA, whereas the rest of the segments regress before birth. If the 10th to 12th vitelline arteries regress with abnormal persistence of ventral anastomosis, a celiacomesenteric trunk is formed. [CA—celiac  axis, SMA—superior mesenteric artery, HA—hepatic artery, SA—splenic artery, LGA—left gastric artery] (Note: Figure adapted from Alam et al. [18])
