Unnamed branch aortic vessel complicated by aneurysmal degeneration

Abstract

Visceral arterial aneurysms (VAA's) are rare and even more so in the setting of aberrant anatomy. Increasing incidental diagnosis has increased detection as well as presented the opportunity for intervention. Etiology is largely unknown and factors predictive of growth and rupture are poorly understood. Thresholds for intervention vary by aneurysm location, etiology, and patient-specific factors such as pregnancy. Endovascular therapy (EVT), open surgery, and hybridized surgical treatment have been described without significant differences in mortality. We present the case of a 37-year-old multiparous female who presented with an incidentally discovered aneurysmal unnamed branch aortic vessel which was successfully managed by open surgical ligation. To our knowledge this is the first report of aneurysmal disease of an unnamed branch aortic vessel.
