This is a patient who is around post-op one
0:03
post-op day two from a pediatric on
0:06
block transplant 2 has diminished graph

function. And so we're asked to evaluate it on ultrasound start off
0:12
with a bladder image. You can see the fully catheter within it.
0:15
You can see a one of the two renal transplants here
0:18
and grayscale image.
0:20
This one is the one deemed more lateral on the
0:23
grayscale image looks relatively. Okay, but look what happens on the
0:26
color image?
0:27
You know flow at all.
0:30
Within this transplanted kidney. So that's quite worrisome. We
0:33
also use techniques to optimize any possibility
0:36
of slow flow or low flow within the kidney and we're
0:39
really not seeing in this instance. This really should
0:42
light up where it's not lighting up at all.
0:45
Again, looking at this kidney and other low
0:48
flow techniques no flow within this kidney.
0:50
We're now looking at some of the anastomoses. We
0:53
see a vessel over here, which is the external iliac vein.
0:56
We see the external iliac artery adjacent to and this
0:59
is the donor aorta for the Pediatric on block. That's an ass to most
1:02
to it. There's a little bit of flow within it but beyond it absolutely
1:05
no flow over here. So that is quite worrisome.
1:09
And we try interrogating it as well with color
1:12
Doppler Imaging. We're not seeing any flow within the renal transplant.
1:16
We see a little bit of flow within this renal aorta over here, but essentially
1:19
very high resistive flow suggesting that
1:22
there's lots of vascular resistance more distally.
1:26
Adjacent to that aorta. We actually see the IVC over
1:29
here, which I'll get has no flow within it the IVC
1:32
of the Pediatric on block renal transplants. So that's completely thrombosed as
1:35
well. And so this was sort of a very traumatic
1:38
case of
1:40
Renal artery thrombosis and renal anthrombosis
1:43
in the immediate postoperative setting and we
1:46
certainly looked at the lateral kidney here. We look at the medial kidney shows the same
1:49
findings with absolutely no flow scene within it this happens very
1:52
very uncommonly when it does happen and we'll see in a
1:55
very early post-operative period and this why
1:58
you do those transplants and immediate postoperative setting
2:01
to look for flow to look for these rare complications, which unfortunately
