In medicine, we say something is pathonomic when it's characteristic for a particular disease.

Like a pathinemonic sign is some kind of particular sign where the presence means that the particular disease is present beyond a reasonable doubt.

And so this makes it diagnostic or helpful or indicative of the disease that we're worried about.

And there are numerous types of pathinemonic findings.

For example, we see owl eyes and inclusion bodies

with cytomegalovirus, or with Lyme disease,

we see arithymacronic migrants.

With patients who have hypocalcemia, you know the signs, it's Truveau and Shavostex.

And then there is a phrase that we use in patients who have severe abdominal pain, that's pain out of proportion to physical exam which can mean

one or two things. The most common and most pathinemonic that we now in this

day and age use that to be attributed for is acute mesenteric is a cute mesenterech ischemia. That's right folks we're going to be attributed for is acute mesenteric

ischemia.

That's right folks, we're going to be continuing our

abdominal vascular pathologies with this episode on acute mesenteric

ischemia.

I'm Dr. Nakeet-Son-P Paul, your friendly neighborhood internist and

gastrointestinalologist, so let's kick it off and talk about this excruciating

disease. So what is acute mesentereic ischemia? Well, it's akin to a myocardial infarction of the gut.

In acute mesentere iskemae, you have the sudden onset of severe hypoprofusion and this is usually and most commonly due to an embolic phenomenon to the superior mesentereic artery.

Now we talked before about SMA syndrome. This is an

SMA occlusion and it's a full-on infarction. So let's go over a little bit of

the actual anatomy of the gut. Remember, the SMA supplies the entire small intestine except for the proximal duodenum.
