All right. So we saw earlier what a bypass graft to the

0:04

inflow looks like, which means axillofemoral or fem-fem or

0:08

femorofemoral. Now we're going to look at normal bypass grafts

0:12

in the outflow and runoff. And so we're going to focus on just that

0:16

normal appearance of those grafts.

0:19

And so obviously, we're looking at the inflow vessels and everything.

0:23

We see stranding in the groin, which is suggestive of

0:26

post-surgical changes right here.

0:28

And then this is a patent femoral

0:33

popliteal bypass graft. So you can see that it extends all the way

0:37

from that common femoral artery, and then it goes all the way

0:41

here.

0:43

You can see that it has this ringed appearance, so you know that this is

0:47

definitely a bypass graft. You have this post-surgical change in that medial

0:51

soft tissue right here.

0:53

And really, as we're going, you can see here we've outrun the bolus

0:57

and

0:59

our scan was faster than the contrast bolus.

1:02

So we're going to swap in our immediate delay scans right here, and we can see

1:06

that there's better contrast opacification of the vessels now.

1:10

And as we're scrolling down, we can see that that femoral

1:13

popliteal bypass graft is patent. The anastomosis is okay.

1:17

There's no complications.

1:19

There is, however, another bypass graft now at the level of the runoff.

1:22

So this is another bypass graft that's going from

1:26

that popliteal artery, and then it's anastomosing right

1:30

here to that anterior tibial artery right here.

1:33

And so really, this person doesn't really have much other vessels that are

1:37

doing any work in that left lower extremity, and it's all up to that anterior

1:41

tibial artery and this bypass graft that are really

1:44

performing the inflow and outflow

1:48

structures for that left lower extremity.
