(B) Sagittal CTA showing that the true and false lumens were separated by an intimal flap (black arrow). (C) CTA volume rendering showing the true and false lumens. (D) Longitudinal CTA showing the entry and re-entry sites. (E) Sagittal CTA showing complete occlusion of the SMA. (F) DSA showing complete occlusion of the SMA. The yellow arrow represents the true lumen; the white arrow represents the false lumen; the blue arrow represents the entry site or re-entry site; and the red arrow shows complete occlusion of the SMA.
