Arc of Buhler

The arc of Buhler (AOB) is a persistent embryonic anastomotic branch between 10th and 13th ventral segmental arteries resulting in a connection between the coeliac artery and superior mesenteric artery.  This arch is independent of both the gastroduodenal and dorsal pancreatic artery.

It travels vertically, ventral to the abdominal aorta and connects coeliac trunk and SMA.  It is present in 1-4% of individuals and provides a collateral pathway between the two vascular territories.

It is named after Dr A Buhler who first described it in 1904 6.
