A common origin of the celiac trunk and superior mesenteric artery is exceedingly rare, and aneurysms of this common trunk are even rarer. According to our literature search, there are no reported cases of nutcracker syndrome or phenomenon involving this rare aneurysmal anomaly. Repair of such anomalies is standardly via open surgical approach with few reported cases of endovascular repair. We describe a patient with an aneurysm of the celiomesenteric trunk resulting in nutcracker phenomenon of the left renal vein. The celiomesenteric trunk aneurysm was repaired endovascularly, resulting in decreased surrounding inflammation and improvement of the left renal vein compression.
