CT angiogram of the abdomen, axial cut, demonstrating the aorta (blue arrow), the CMT (green arrow), and celiac trunk stenosis (black arrow). The left gastric artery (red arrow) and hepatic artery (yellow arrow) are also seen.

This prompted further evaluation with computed tomography angiography (CTA) scan of the chest, abdomen, and pelvis, which demonstrated celiacomesenteric trunk with severe narrowing of the celiac trunk, and saccular aneurysmal dilatation of the SMA measuring up to 1.3 cm in the anteroposterior (AP) diameter, 1.5 cm in the transverse axis, and 1.8 cm in height (Figures 2-4). Subsequently, the aneurysm sac was embolized with two 22-mm/65-cm Cosmos microcoils until the neck of the aneurysm was completely sealed (Figure 5, Video 2 in Supplemental Material).
CT angiogram of the abdomen, axial cut, demonstrating superior mesenteric artery aneurysm (black arrow) and the superior mesenteric artery (red arrow).

This prompted further evaluation with computed tomography angiography (CTA) scan of the chest, abdomen, and pelvis, which demonstrated celiacomesenteric trunk with severe narrowing of the celiac trunk, and saccular aneurysmal dilatation of the SMA measuring up to 1.3 cm in the anteroposterior (AP) diameter, 1.5 cm in the transverse axis, and 1.8 cm in height (Figures 2-4).
3D reconstruction from CT angiography of the chest, abdomen, and pelvis, demonstrating aneurysm in the superior mesenteric artery (black arrow). Black circle shows the CMT. The splenic artery is highlighted by the yellow arrow, and the hepatic artery, by the red arrow. The SMA is highlighted by the gray arrow, and the green arrow shows the enlarged inferior pancreaticoduodenal artery.

Aneurysm sac embolized with two 22-mm/65-cm Cosmos microcoils with complete seal of the neck of the aneurysm. Notice the enlarged inferior pancreaticoduodenal artery (white arrow).
