Abstract

Inferior mesenteric artery (IMA) aneurysms account for approximately 1% of visceral artery aneurysms and can occur secondary to high flow because of occlusive disease in other mesenteric arteries. We describe the case of a 79-year-old man who presented with a 3.3-cm IMA aneurysm and chronic total occlusions of the celiac artery and superior mesenteric artery (SMA). After an unsuccessful attempt at endovascular SMA recanalization, he underwent an uncomplicated retrograde aorta to SMA bypass and antegrade aorta to IMA bypass. We propose that an aorta to IMA bypass after SMA revascularization is safe and effective to treat suspected high-flow IMA aneurysms.
