0:00

So this is, uh, another, uh, similar example, uh,

0:04

where the patient had a right

0:07

no flow in the right femoral artery.

0:09

And I just want to show you what,

0:12

what happens when there is an occlusion in our gel system.

0:16

So this is in the femoral artery.

0:19

So when we look more centrally, so above the level

0:23

of the occlusion, then you have good strong,

0:27

this is not really, uh, tri, this is a little bit phasic.

0:31

There's a little bit too much flow in diastole,

0:33

but still there's a strong systolic up stroke, right?

0:36

When you look distal to either an occlusion

0:40

or very significant stenosis,

0:42

then you're gonna have this classic

0:45

TARDIS progress waveform.

0:47

And this is why I have this, um, this case here to show

0:51

that there is lack of a sharp, normal systolic up stroke.

0:56

It's too, um, the slope is too slow

0:59

and there is a lot of diastolic flow

1:02

because there is also very turbulent flow.

1:04

Okay? So this tardis parvis waveform, you're gonna see

1:09

more distal to either an occlusion

1:13

or a severe stenosis.

1:15

And you can apply this in the leg, you can apply

1:18

that in the liver, in the kidney, uh, wherever.

1:22

This is a very, very important TARDIS progress,

1:26

abnormal waveform to, to register to keep in mind.

1:30

So again, it's very important to avoid tunnel vision.

1:34

Um, and you know, and just look around.

1:38

I showed you abnormal lymph nodes, fluid collections,

1:40

arterial abnormalities when you do a TBT study.
