Bühler's anastomotic artery
In human anatomy, Bühler's anastamotic artery (also called the arc of Bühler's) is an anastomotic shunt joining the superior mesenteric artery and the celiac trunk in vertical orientation.
Anatomy[edit | edit source]
As the aforesaid arteries arise separately from different levels of the abdominal aorta, the shunt provides limited collateral circulation should a blockage occur in the intervening arterial segment.
Incidence[edit | edit source]
Bühler's artery is a rare phenomenon present in up to 3% of the population.
Embryology[edit | edit source]
It is thought to be an unobliterated remnant of the ventral longitudinal anastomosis present during embryological development.
