CT scan (a) showing an unfolded aorta demonstrating the aortic dissection from the
ascending aorta to the iliac arteries. Three-dimensional CT renderings of the aorta show
the aortic dissection in different views around the aortic arch and down the descending
aorta (b and c), thoracic aorta towards the iliac arteries. Note the small reduction in
contrast uptake by the left kidney which is attached to the false lumen (red arrow).

The CT confirmed a large 5-cm aortic root with a type A intimomedial aortic dissection (AoD) flap originating at the ascending aorta extending (Figure 1) along the entire length of the thoracoabdominal aorta terminating at the common iliac arteries bilaterally.
CT of the aorta cross sectional view of the aortic arch showing the aortic
dissection.

The right renal artery connected to the true lumen while the left renal artery arose from a false lumen with a relative reduction in kidney contrast enhancement (Figure 2). The RCA ostia were likely attached to the false lumen obstructing coronary flow and causing the initial presentation of the acute inferior myocardial infarction and subsequent cardiac arrest, which was treated by PPCI.
