Celiac trunk and mesenteric artery aneurysms are relatively rare, with superior mesenteric artery aneurysms accounting for approximately 8% of all visceral artery aneurysms. Most cases are asymptomatic, although symptoms such as intestinal ischemia, abdominal discomfort or pain due to aneurysmal compression, gastrointestinal bleeding, or hemorrhage into the abdominal cavity or retroperitoneum may occur. Severe consequences may arise if intestinal ischemia and necrosis develop. Clinical diagnosis is often challenging and typically requires confirmation through CTA or angiography.

In addition to aneurysm resection with vascular reconstruction, endovascular minimally invasive techniques have increasingly been employed for treatment in recent years.
