0:00

What about this case?

0:02

So here you have, um,

0:06

a tight velocity here.

0:10

Um, also in the, um, in the, in the

0:16

internal, um, I'm sorry, right iliac artery.

0:20

Okay. And he, here's the other side for comparison again.

0:26

So here you see the velocity

0:28

in the artery is 75 centimeters.

0:31

Second in the white common femoral artery

0:34

in the iliac artery, you can barely see it,

0:36

but the velocity is extremely high.

0:42

So there is an and, and there, there, there are plaques.

0:46

So there is a big gradient. Okay?

0:48

So what's you need to look for when you look at stenosis,

0:52

you look for a gradient.

0:54

Uh, and in this particular case, the ratio between the right

0:59

internal I artery

1:00

with the right common fem artery was more than, uh,

1:03

two to five to one.

1:04

And that's an indication that there is a severe stenosis

1:07

because of the gradient.

1:11

So what other criteria for stenosis might always think?

1:15

I don't like remembering numbers. I say keep it simple.

1:17

If you have a p systolic velocity gradient of more than two

1:22

to one or 2.5, two, one, you have

1:26

to think about the possible of stenosis in

1:29

between those two segment of 50% of more.

1:32

And again, if you're not sure,

1:33

always look at the other side.
