Endovascular treatment of pancreaticoduodenal aneurysm with braided stent-assisted coil embolization using intraoperative cone-beam computed tomography guidance.

Pancreaticoduodenal arterial arcade aneurysms are rare but are prone to rupture. We report the case of a 60-year-old woman with an asymptomatic pancreaticoduodenal artery aneurysm and concomitant celiac trunk occlusion that was treated using an endovascular approach. After percutaneous transfemoral access and superior mesenteric artery cannulation, intraoperative cone-beam computed tomography angiography was performed to better understand the aneurysm morphology and provide image guidance. On selecting the optimal working projection, the aneurysm and distal parent vessel were cannulated and treated by braided stent (low-profile visualized intraluminal support; MicroVention)-assisted coil embolization. Completion angiography and cone-beam computed tomography confirmed successful exclusion of the aneurysm sac and a patent pancreaticoduodenal arcade with a well-apposed stent.
