Background: The abdominal aorta is supplying the digestive tract with three unpaired arteries, which are connected during the early intraembryonic development through the longitudinal anastomosis of Tandler. If the anastomotic system does not regress completely, variant connections may remain. Methods: During routine dissection of a female cadaver an anomalous artery was found. Results: This artery formed an anastomosis between left colic, and transverse pancreatic arteries. The celiac trunk showed normal trifurcation. The common hepatic artery gave off the right gastric, the proper hepatic and the gastroduodenal branches. The gastroduodenal artery had a bifurcation to transverse pancreatic and right gastroomental arteries. Transverse pancreatic gave origin with a common trunk to the anterior superior pancreaticoduodenal and the anastomosis forming vessel. The anastomosis turned from the front of the superior mesenteric artery to the back of superior mesenteric vein. Superior and inferior mesenteric arteries had primary branches according to normal anatomy. Conclusion: Occurrence of such variation stresses the importance of preoperative angiography in abdominal surgery. Surgical relevance in pancreatic resections: this variant artery must be ligated to avoid bleeding during intervention. Furthermore, this variant anastomosis can be a hidden source of bleeding in severe necrotizing type of acute pancreatitis due to erosion. |
