Figure 1 (A–E) Computed tomographic angiography (axial view) revealed the 3.6-cm prehilar splenic artery aneurysm (arrow in [A]). Cone-beam computed tomography (coronal view) documented extent of the aneurysmal sac, and the afferent and efferent arterial segment of the splenic artery (arrows in [B]). Embolization was performed in a 3-step approach. First the arterial “back door” was occluded by using two 6 mm-diameter/14 cm-length nester coils (arrow in [C]). Second, the aneurysmal sac was occluded by using a 22 mm-diameter/18 mm-length Amplatzer vascular plug II (arrows in [D]). Third, the afferent “front door” was occluded by using two 8 mm-diameter/14 cm-length nester coils (arrows in [E]).

Figure 2 (A, B) Two-dimensional digital subtraction angiography revealed the extent of the aneurysmal sac 8 (arrow in [A]) and visualized the afferent and efferent arterial segment of the splenic artery aneurysm; however, a short gastric artery, originating from the aneurysmal sac was not seen on digital subtraction angiography images but revealed on cone-beam CT (arrow in [B]).
