As the name implies, this will be issues with the vascular system.
The patient is gonna present with abdominal pain and rectal bleeding,
in the setting of decreased perfusion,
in a background of chronic diffuse mesenteric vascular disease.
We'll get into further detail with the mesenteric ischemia
and the different or probable pathogenesis,
but at this point understand that due to the ischemia,
you will have issues with intestine in which the patient is going to present with rectal bleeding.
Remember this is a red type of infarct because we have two more blood supplies
taking place with the colon. Accompany dehydration, sepsis and hypertension.
You are worried about sepsis here with ischemia.
Quite dangerous and more or less an emergency type of matter,
commonly involves the watershed area, if you remember that watershed would be that area
or tissue in which you would have one and two vascular systems
then supplying or perfusing that tissue. If one goes out, then the other one will take over
resulting in hemorrhage into. That is watershed.
Radiographically the feature here that I show you is 'thumbprinting'.
And your management here would be supportive care with IV fluid
because you're worried about loss of fluid and because of loss of fluid
blood pressure control is important and antibiotics
because here you are dealing with ischemic colitis.
On your left is your normal colon and then on the right is representative of ischemic colitis,
the arrows are then pointing to your 'thumbprinting'.
