Ascending aorta DISSECTION is not a traumatic injury, and is totally
unrelated pathologically to traumatic aortic RUPTURE which is most
commonly seen at the level of the ligamentum arteroisum / left
subclavian artery.

We recently had a small plane pilot crash victim allergic to iodine and
so assessed the aorta with TEE.
Typical ascending aorta dissections are relatively easy to diagnose
with a visible flap and a second lumen with flow.
Commonly there is also AI and pericardial effusion accompanying. Arch
is not visible on TEE due to the left mainstem bronchus interposition.
Descending aorta is nicely visible on long and short axis ("tube" and
"salami" cuts), typical site transsections are accessible. One can also
see AIH - aortic intramural hematomas - no flow in the accessory lumen.
There are VOMITs possible - the arch cen have a reverberation artifact
which looks like a second lumen. Also, which happened in our case, there
is the left innominate vein which normally adheres to the arch and has
flow in the opposite direction, which can be pulsatile so close to the
right heart, especially with e.g. TR. It too can mimic a dissection.

It is really hard to see the ct Ao injury which I think that is what
you r trying to point out. In the event of a true (not a VOMIT) Ao
injury with combine TBI, non operative management with control of
patient delta P/delta T with breviblock is indicated. On the other hand
special attention needs to be taken for good ICP/CPP readings in order
to prevent secondary brain injury. Good judgment and close ICU care is a
most.
Please send more cuts of the CT.
Always remember communication is of the essence among physicians in
polytrauma patients.
Good case.
