Fig. 1. Emergency computed tomographic angiography was obtained on admission. (A) Coronal reconstruction image demonstrated a dissection of the celiac trunk spreading from ostium to the proximal splenic artery with intimal flap (white arrow). The true lumen provides perfusion to the splenic artery while hepatic artery was perfused from the false lumen (not shown). (B–D) An approximately 4-cm-long dissection of the superior mesenteric artery from orifice with thrombus formation in the false lumen (black arrow) and severely narrow true lumen (white arrow) were evident on axial and maximum intensity projection sagittal reconstruction image (black circle). Bilateral focal renal infarctions (asterisk) were also noticed as a consequence of corresponding renal artery dissections (white circle).
