We've been talking about ischemia to the gut for many, many weeks now.

We've talked about celiac arteries, superior mesenteric arteries.

We've talked about blood clots going to the abdomen causing infarctions,

even chronic mesenteric

aschemia which causes forms of angina that normally people feel in

their chest, but with patients who have chronic mesenteric

is in the abdomen. Now this week we're going to round out our topic of

is basically that reduction of blood flow that's insufficient for the

delivery of oxygen talking about colonic ischemia. Now believe it or not colonic ischemia.

Now, believe it or not, colonic is the most frequent form of intestinal

is the most frequent form of intestinal ischemia and it affects mostly older patients.

You're going to see this a great deal. And for most of you, you've probably run across this in your inpatient rotations,

but approximately 15% of patients with colonic ischemia

actually develop necrotic bowel.

So it's important for us to understand how to make the diagnosis and who needs what kind of treatment.

I'm Dr. Nakeet Son Paul, your friendly neighborhood internist and gastrantrologist and gastontrolologist and podcast host.

Let's jump into the topic. Now we know that the colon itself is very very vulnerable to hyper-perfusion and when we talk

about the colon which part of it is most susceptible

to ischemia? It's the mucosa. And the reason why, it's furthest from blood supply.

Now the blood supply of the colon and the rectum is primarily from the SMA, the IMA, and the internal

ailiac arteries.

And for the purposes of discussion, there are two types of ischemicalitis.
