Images from Case 1. a, b Fluoroscopic images during coil embolization showing embolization of the inferior pancreaticoduodenal artery (PDA) combined with packing of the aneurysms. Additional embolization with coils is shown in the branch of the inferior PDA (black arrows) and first jejunal artery (white arrow) arising from the proximal inferior PDA to prevent reperfusion of the PDA aneurysms (PDAAs). c Post-embolization angiogram via the superior mesenteric artery showing complete occlusion of the aneurysms. d Contrast-enhanced magnetic resonance imaging after treatment showing disappearance of the arterial flow in the proximal PDAA (white arrow) and decreased thickness of the pancreatic arcades (white arrowheads)
