Hybrid Surgery to Treat Multiple Visceral Aneurysms Secondary to Polyarteritis Nodosa

A 57-year-old woman presented to vascular surgery clinic with visceral artery aneurysms that were incidentally detected during regular check-up. Imaging studies revealed occlusion of the celiac axis and severe stenosis of the superior mesenteric artery and 3 aneurysms along the posterior and inferior pancreaticoduodenal arteries, as well as the right gastroepiploic artery. Endovascular embolization of all aneurysms was rejected because of the risk of hepatic ischemia. These complicated lesion caused by polyarteritis nodosa were successfully treated using a hybrid operation with coil embolization, aneurysm resection, and antegrade aorto-celiac-superior mesentery artery bypass.
