arc of Buhler
The arc of Buhler (AOB) is a persistent embryonic anastomotic branch between the 10 and 13 ventral segmental arteries, resulting in a connection between the celiac artery and superior mesenteric artery (SMA). This arch is independent of both the gastroduodenal and dorsal pancreatic artery.
It travels vertically, ventral to the abdominal aorta, and connects the celiac artery and SMA. It is present in 1-4% of individuals and provides a collateral pathway between the two vascular territories.
History and etymology
It is named after Dr A Buhler who first described it in 1904.
