Hybrid approach to intrapancreatic inferior pancreaticoduodenal aneurysm repair.

Pancreaticoduodenal artery aneurysms (PDAAs) are an extremely rare visceral artery aneurysm subtype, usually managed by endovascular techniques. We report the case of a 57-year-old man with an intrapancreatic, inferior PDAA abutting the superior mesenteric artery (SMA). This location, in relation to the SMA, risks SMA thrombosis using an endovascular-only approach. Our approach consisted of open exploration and ligation of the inferior PDAA junction at the SMA, followed by endovascular coil embolization of the aneurysm. This case serves as a reminder that although many vascular diseases can be treated with less invasive endovascular strategies, open surgery can sometimes be the safer alternative.
