Segmental Arterial Mediolysis of Omental Arteries with Haemoperitoneum: Case Report with Embolization of the Left Omental Artery and Brief Review of Literature

Figure 3

Digital subtraction angiograms. Splenic arteriogram (a) with a markedly dilatated segment, respectively, spindle-shaped aneurysm (arrow) of the left omental artery (LOA), better visible in the late phase (b) and with separate origin of the LOA from an inferior splenic pole artery. Superselective arteriogram of the LOA (c) before embolization (noteworthy, the tortuous microcatheter in the substantially elongated splenic artery). Postembolization arteriogram of the splenic artery demonstrating NBCA-casting and stasis of the LOA (arrow) with preserved splenic arteries (d).
