Why the study?
Malperfusion syndrome in acute type B aortic dissection is a negative predictive factor requiring urgent intervention, but anatomic variations like the Arc of Buhler can preserve visceral perfusion.
The presence of the Arc of Buhler can preserve visceral blood supply in complicated acute type B aortic dissection with celiac artery occlusion, allowing for effective treatment with TEVAR.

Arc of Buhler may preserve visceral perfusion in type B dissection; leaves open whether variants alter intervention thresholds.
The presence of malperfusion syndrome in cases of complicated acute type B aortic dissection is a negative predictive factor and urgent intervention is indicated. Anatomic variations, such as the Arc of Buhler, contribute anastomotic channels and can preserve the visceral blood supply. In this case report, we describe the overall management of a 54-year-old man who presented with a type B aortic dissection. Initially, conservative management was chosen, as indicated for an uncomplicated type B dissection, but the dissection deteriorated. Despite the fact that severe occlusion of the celiac artery was detected on Computed Tomography (CT) angiography, the Arc of Buhler anatomical variation was present, contributing adequate visceral blood supply. After considering this finding, the patient was treated effectively with thoracic endovascular aortic repair (TEVAR).
