Okay, so this is another patient given me, given
0:03
to me by my friend Dr.
0:04
But again, in the upper extremity, same concept.
0:09
So if you look at, so this patient had a, um,
0:15
digit discolor, the acute fifth digit pain
0:18
and discoloration on the left side.
0:21
And so when they did the doppler, um,
0:26
we couldn't really see centrally, right?
0:28
They couldn't see centrally.
0:29
But this is what was noticed that's very important is that
0:32
in the axillary artery as well as the radial artery,
0:36
you have a tars harvest wave one.
0:40
This should be a strong phasic flow
0:43
with sharp systolic up stroke
0:45
and reversal ofone diastole, we did not see that.
0:48
So based on that alone,
0:50
because they couldn't see centrally where the problem was,
0:52
ultrasound cannot reach there.
0:54
But based on that, they said, look, okay,
0:56
this patient may have a more central occlusion of stenosis.
1:00
The patient needs a CTA.
1:02
And so when they did the CTA, you can see that in the
1:06
subclavian artery here, there is a clot
1:09
with near complete occlusion on the mip.
1:11
Very nicely shown. So again,
1:13
this is why I think we dopper what's so important.
1:16
It's not just to see there is flow and no flow
1:18
'cause the, the, the, the arteries are patent here,
1:20
however, analyze the darker spectrum
1:23
and from that infer that there may be something that's
1:26
beyond what you can see and recommend the appropriate study.
