Endovascular Treatment of a Saccular Aneurysm in the Celiomesenteric Trunk: A Case Report and Review of Literature

To present a world-first case of a successful endovascular treatment of a celiomesenteric trunk (CMT) aneurysm. A 45-year-old man had an asymptomatic saccular aneurysm in a rare anomaly of CMT. Endovascular multiple micro-coil embolization of the common hepatic artery, splenic artery and the aneurysm was done, followed by a stent-graft deployment in the superior mesenteric artery covering the orifice to the aneurysm. Postoperative course was uneventful. Only 21 cases have been previously reported in the literature, and all were treated by open surgeries. Endovascular therapy can be safely done in selected cases of a CMT aneurysm with sufficient collaterals to the liver and spleen.
