Hybrid management approach for superior mesenteric artery and branch aneurysms

Abstract

Visceral artery aneurysms are rare, with a 25% rupture risk and an associated 70% mortality. A 55-year-old woman with progressive epigastric pain was found to have multiple large superior mesenteric artery (SMA), branch, and gastroduodenal artery aneurysms along with an occluded celiac artery trunk with hepatic flow dependent on the aneurysm branch. Management included antegrade aortohepatic artery bypass with gastroduodenal artery ligation, followed by SMA stenting and aneurysm coiling. This case is novel, given the diffuse pattern and rarity of SMA and branch aneurysms. This hybrid surgical management highlights innovative strategies to minimize morbidity without compromising definitive treatment of complex visceral artery aneurysms.
