Okay, so this was an example of renal artery stenosis.

0:04

This was a challenging exam because this exam is actually performed portably, and

0:08

we actually don't typically perform these exams in the portable setting because

0:11

they are so technically difficult to do in patients who are unstable enough to come

0:16

down. However, they were really concerned about the potential for renovascular

0:20

hypertension in this patient. So you can see as we start on the left, we don't get

0:24

the greatest view of what that left renal artery looks like.

0:28

We are getting an arterial waveform, but we're not really able to very well

0:33

represent what we think that is. We even initially struggled on the right side.

0:38

We were really struggling to find a window and see what we needed to see.

0:42

However, with additional interrogation, we were able to clean that area up a good

0:47

bit, and through a different window, we were able to better evaluate the renal

0:53

artery. You can see here as it separates from the aorta, we can see significant

0:58

aliasing within that area and turbulence, and then the velocities are significantly

1:03

elevated here. So we were up to 335 centimeters per second.

1:07

So that was consistent with a unilateral renal artery stenosis, and this patient

1:11

did have renovascular hypertension.
