INTESTINAL ISCHEMIA

Question 1

caused by reduced intestinal blood flow

acute and chronic intestinal ischemia

small intestine?
large intestine?

Answer 1

intestinal ischemia

*mesenteric ischemia, colonic ischemia

Question 2

arterial thrombosis in setting of underlying vascular idsease

arterial embolism from dislodged thrombus

nonocclusive mesenteric ischemia

venous thrombosis

Answer 2

mesenteric ischemia

Question 3

etiology of mesenteric ischemia?

Answer 3

cardiac disease
vasoconstrictor meds
aortic surgery
peripheral artery disease
acquired thrombosis
inflammation
hypovolemia
segmental ischemia

Question 4

most likely symptoms?

Answer 4

abdominal pain, if acute ischemia than out of control pain and if recurrent than chronic mesenteric

Question 5

acute mesenteric ischemia presents how?

Answer 5

underlying PAD with thrombotic mesenteric arterial occlusion and worsened postprandial pain

if arterial embolism than sudden, severe, periumbilical pain with N/V

Question 6

more variable
causes of NOMI
hypotension
heart failure
hypovolemia
cardiac arrhythmias

symptoms of?

Answer 6

mesenteric ischemia

Question 7

rapid onset of mild abdominal pain

mild to moderate amounts of rectal bleeding or bloody diarrhea

Answer 7

colonic ischemia

Question 8

acute presentation of severe mesenteric ischemia?

Answer 8

vasodilatory shock from sepsis

respiratory insufficiency

acute kidney injury

Question 9

management of mesenteric ischemia?

Answer 9

resuscitation
anticoagulation for intestinal blood flow
depends on etilogy
