The celiaco-mesenteric anastomoses occur either directly between the celiac trunk and the superior mesenteric artery (SMA), or between different branches of them. A rarely occurring such anastomosis is the arc of Bühler. A new variant of arc of Bühler was found incidentally during a retrospective study of the computed tomography angiograms of a 62 y.o. male patient. In that case, the arc of Bühler left from the splenic artery and inserted into the inferior pancreaticoduodenal artery (IPDA), proximally to the IPDA division into its anterior and posterior branches. Moreover, that arc of Bühler was giving off a mesenterico-jejunal branch, which descended applied on the anterior side of the SMA. Such anatomic variants could impede on the surgical or interventional procedures in the duodenopancreatic region, or could be physiologically useful to divert the celiac flow towards the mesenteric territory, or vice versa.
腹腔肠系膜吻合发生在腹腔干和肠系膜上动脉（SMA）之间，或者它们的不同分支之间。一种罕见的吻合是布勒氏弓。在对一名 62 岁男性患者的计算机断层血管造影进行回顾性研究时，偶然发现了布勒氏弓的一种新变异。在这种情况下，布勒氏弓从脾动脉左侧发出，插入胰十二指肠下动脉（IPDA），位于 IPDA 分为前支和后支的近端。此外，该布勒氏弓发出一支肠系膜空肠支，沿 SMA 的前侧下降。这种解剖变异可能会妨碍十二指肠胰腺区域的手术或介入治疗，或者可能在生理上有助于将腹腔血流分流至肠系膜区域，或者反之亦然。
