Abstract
For decades, anastomoses between unpaired branches of the abdominal aorta have attracted the attention of anatomists, surgeons and radiologists, due to their significance in many clinical procedures. This report presents a rare anastomosis between the common hepatic artery and the superior mesenteric artery, which gave off three branches to the jejunum. The diameter of the anastomosis measured at the point of its branching off the common hepatic artery and at the level of union with the superior mesenteric artery was 4.46 and 4.19 mm, respectively. Moreover, the anastomosis gave off the branch to the head of the pancreas. Both embryological background and potential clinical implications of this variation are discussed. Knowledge of these vascular connections may be important for diagnostic and surgical procedures.

Summary
Since the coeliac vascularization is complex, its anatomical variations should be known by hepatic surgeon during transplant procedure. The 10th primitive root of the ventral segmental artery becomes the left gastric artery; the 11th becomes the splenic artery; the 12th becomes the common hepatic artery; the 13th becomes the superior mesenteric artery, and the 19th primitive root becomes the inferior mesenteric artery with separate origins from the abdominal aorta [9, 18, 25]. Iacob et al [9] described an absence of the celiac trunk, with the left gastric and the common hepatic arteries originating directly from the anterior wall of the abdominal aorta. Negovanovic [31] describes the presence of an anastomosis between the common hepatic artery and the superior mesenteric artery in an adult female cadaver This fusion directly connected the CHA and the SMA [31]. As acute mesenteric ischemia accounts for 60–80% of all cases of mesenteric ischemia, and has a mortality rate between 59 and 93% [38,39,40], knowledge of such anatomical variation is important
