Figure 11.10. The involvement of aortic branches in the dissection has to be analyzed carefully starting from the supraaortic vessels, whose involvement can cause neurologic complications. Intimal tears can be appreciated on the axial scan (arrows) at the level of the brachiocephalic trunk and left carotid arteries.

Figure 11.11. Also the splanchnic arteries need to be carefully visualized. In this axial scan, the left renal artery is included in the false lumen that is completely thrombosed, and therefore the renal artery is completely occluded, causing the acute ischemia of the left kidney.
