title: Endovascular management of superior mesenteric artery pseudoaneurysm.
abstract: A 31-year-old man underwent a Whipple procedure for a pancreatic neuroendocrine tumor, which consists of a pancreaticoduodenectomy and reconstruction to restore intestinal continuity. Six weeks after the operation, he presented with severe mid-epigastric pain radiating to his back. Imaging studies revealed a large pseudoaneurysm arising from the superior mesenteric artery. Selective superior mesenteric angiography confirmed the presence of the pseudoaneurysm. A 6 mm × 2.5 cm stent graft (Viabhan; W.L. Gore, Flagstaff, Ariz) was deployed across the pseudoaneurysm origin with preservation of the mesenteric branches. The patient had immediate resolution of symptoms and follow-up imaging showed patency of the stent graft and exclusion of the pseudoaneurysm.
