Case report of an arc of Bühler pancreatic variant in a Brazilian cadaver

Abstract

The present study concerns the persistence of an arc of Bühler pancreatic variant in a Brazilian cadáver. The arc of Bühler, reported by Bühler and Tandler in 1904, is an important and rare vascular anatomical variation of the abdominal cavity. Although the first description dates back more than a century, it is estimated that this variation represents only 1% to 4% of all variations found worldwide, and its presence is often admitted as controversial, because it is not the arc of Bühler per se, but a similar collateral variation. In this context, the aim of the present study is to examine the role of this variation in clinical and surgical presentations of the abdominal cavity, punctuating both the benefits and harms of the presence of this vasculature variant of considerable caliber. The importance of adequately classifying similar structures with different functions is demonstrated, given different medical practice situations. Possible pathologies created exclusively by the presence of this anatomical variation are also highlighted. It is concluded that knowledge concerning the present structure reaffirms the study of human anatomy as one of the foundations of medicine and of its safe, resolutive and inclusive practice within medical aspects. The study was carried out within the parameters established by decree No. 8.501, of November 30, 1992, of the Federative Republic of Brazil1,on the use of unclaimed cadavers for study or scientific research purposes.
