This is a patient who is post-renal transplant

0:03

had a biopsy due to graph dysfunction and

0:06

now has pain at the biopsy site. We get

0:09

the grayscale image showing a left lower quadrino transplant

0:12

looks pretty okay over here.

0:14

And we see some of the collecting system

0:17

over here something that looks a little bit more rounded over

0:20

here. And certainly they haven't appearance of the collecting system.

0:23

However, when you put color flow on it,

0:26

you can see that this portion of a collecting system does not fill which would

0:29

be appropriate. However, this supposed thing that

0:32

looks like a collecting system actually fills with color. So this is a vascular structure

0:35

or sort of come back to that and a

0:38

little bit as we evaluate the remainder of the kidney itself. We can

0:41

see that structure again over here looks very beautiful. We have

0:44

flow that sort of swirling within it resulting in

0:47

flow going towards the trans use your flow going away

0:50

from the transducer and this appearance is

0:53

the classic yin. Yang appearance you see a

0:56

pseudo and

0:58

All right, if you can find the neck of

1:01

the pseudo aneurysm which in this instance is quite difficult to find if

1:04

you can find it you'll end up seeing flow that goes both above

1:07

and below the Baseline over here due to

1:10

the two and four flow scene within pseudo aneurysms. Now pseudo

1:13

aneurysms are uncommon we end up seeing them and

1:16

the post biopsy setting they're often

1:19

small and asymptomatic you start treated if they

1:22

get enlarged if for whatever reason

1:25

they're causing symptoms if they're of a certain

1:28

size generally above two centimeters you consider treatment,

1:31

but the key thing is to be able to diagnosis and if

1:34

you didn't show Color images on this you may think it's portion of the collecting system

1:37

or assist putting the color images such as

1:40

that diagnosis of a pseudo aneurysm
