Okay. Another contrast-enhanced CT scan of the
0:03
abdomen and pelvis. Coming down, we're going to see
0:05
the liver and spleen are looking pretty good.
0:08
As we come down into the left lower quadrant, again,
0:11
we're going to see multiple diverticulum along the
0:14
colon, some inflammatory changes as well. Down
0:18
into the pelvis, it even gets more dramatic.
0:21
Here we go.
0:23
This is diverticulitis, so this is nice diverticulitis.
0:25
Now I want you to look for next-level
0:27
stuff, because just being normal is not as
0:30
much fun as being extraordinary, right?
0:32
So here we have diverticulitis, but the next thing
0:35
you're going to look for in diverticulitis is
0:37
to make sure that you don't have any, you know,
0:39
disseminated liver abscesses. You don't here.
0:41
But if you look carefully at the portal vein,
0:44
you're going to see that you have a thrombosis
0:46
within the portal vein, here at the confluence.
0:48
Here's the SMV.
0:50
Here's the portal vein.
0:51
What's this little vein?
0:53
That's all thrombus.
0:54
Oh my gosh.
0:55
That little vein is going
0:57
anterior to the left renal vein.
0:59
Let's see where we can find the left renal vein.
1:01
Oh, left renal vein, and coming
1:02
down into the left lower quadrant.
1:05
This vein goes all the way
1:07
down into the rectum as well.
1:08
People don't love this vein as much
1:10
as I do, but you're going to be one of
1:12
the people who loves it as much as me.
1:13
So we have thrombosis
1:15
of this vein coming all the way over.
1:17
This, my friends, is the IMV,
1:19
the inferior mesenteric vein.
1:21
You can get IMV thrombophlebitis
1:24
in the setting of diverticulitis.
1:25
I see it maybe three to five times a year, maybe three,
1:29
which is actually quite a bit, and it is definitely
1:32
something that you want to diagnose when present,
1:34
because these patients need to be anticoagulated,
1:36
and this is a higher-level diverticulitis as well.
