Giant visceral artery pseudoaneurysm treated with endovascular transradial coil embolization

Abstract

Visceral artery pseudoaneurysms (PSAs) are relatively rare, and cases associated with distal vasculature of the superior mesenteric artery are largely unreported. Visceral artery PSAs, without intervention, can lead to morbidity or mortality from rupture or mesenteric ischemia. Historically, open aneurysmectomy is the gold standard; however, endovascular modalities have emerged as the first-line treatment in patients who are poor surgical candidates and/or have unfavorable anatomy. Herein, we describe a case of a symptomatic PSA of the distal superior mesenteric artery treated via the transradial approach with endovascular coil embolization, showing successful aneurysmal exclusion and preservation of enteric collateral flow.
