The incidence of the Arc of Buhler ranges from 1-4% in the few studies investigating it, and its diameter has been assessed at 1.5 - 2.5 mm.
|In these two images from a celiac axis arteriogram, the superior mesenteric artery fills through an enlarged vessel extending off the inferior aspect of the celiac trunk -- a hemodynamically significant Arc of Buhler.|
Although noting its presence can be significant for preoperative planning or pre-TACE planning., aneurysms of the Arc of Buhler have also been reported, and treated with coil embolization.
