Hi, there. My name is Lawrence J. Brandt,
and I am Professor of Medicine and Surgery at Albert Einstein College of Medicine.
I'm the Emeritus Chief of Gastroenterology at Montefiore Medical Center.
I'm going to be speaking to you about the spectrum of GI ischemia.
Because this subject has grown over the last number of years,
I have divided this talk into two parts.
In the first part, we'll just discuss colon ischemia.
In the second part, we'll discuss a broad range of topics,
including acute mesenteric ischemia,
focal segmental ischemia, mesenteric arterial occlusive disease,
mesenteric venous disease, and chronic mesenteric ischemia or intestinal angina.
Thank you. Let's begin.
The spectrum of GI ischemic disorders is exactly that.
It is a wide variety of
intestinal disorders that have in common a reduction in intestinal blood flow.
These can be divided into several types.
It is colon ischemia,
which is the most common acute mesenteric ischemia,
which in and of itself is a spectrum of disease that we will talk about later-
that is less common.
Short segments of the intestine can be involved.
So-called focal segmental ischemia-
that's even less common.
The least common is intestinal angina
or chronic mesenteric ischemia.
Increasingly common is mesenteric venous thrombosis.
The reason this is increasingly common is
because of all the CAT scans that we're doing today and
we're finding so many of these thrombi that had minimal or no symptoms.
