Cardiac Findings on Non-Gated Thoracic CT Case 14

HIDE
PrevNext

0:00

So let me just show one more case and then

0:03

we're just going to wrap up and this is in keeping with that theme and

0:06

let's just scroll through a few images here.

0:12

Now limit your field of view

0:15

to just these few images just because we're running short on time

0:18

and let's open the polling and see what you think about the abnormality in

0:22

this case.

0:26

So where is the major abnormality?

0:29

And let's give a couple seconds to vote.

0:34

Okay, so let's close that poll and see

0:37

what people thought.

0:40

Okay, so everyone said corny arteries or grass and

0:43

so this is an important case because it highlights this which

0:46

is a seven Spain

0:49

graph that's coming off of the order and it's going to come off.

0:52

If you notice not off of the aortic root

0:55

where then the native coronaries come off. You can see their RCA

0:58

right there, but it's kind of come off above the

1:01

native coronaries along the

1:04

Asin aorta. And this one is if you follow this,

1:07

it's occluded. It just goes into nothing. You can

1:10

often see what's called a ghost of the graph which is

1:13

right here. You can see just a faint whisp of the remaining thrombosed

1:16

graft. But this is what included graph

1:19

looks like and keep in

1:22

mind that you see the lemograph right there that's patents. And

1:25

so those are a lot less frequently occluded

1:28

over time, but seven graphs

1:32

tend to get included on more frequent basis up

1:35

to 50% of these can be included at 10

1:38

years after the

1:40

Of the graph. So a lot of them will include right at

1:43

the origin or at the stump and leave the just this

1:46

like little stump of enhancement. And the rest

1:49

of the rest of the graft is included so

1:52

Okay. Thanks so much. Thank you.
