The term acute mesenteric ischemia (AMI) is applied to a wide spectrum
of bowel injury within the distribution of the superior mesenteric ve
ssels, ranging from reversible alterations in bowel function to transm
ural necrosis of the bowel wall. Intensivists not only are called upon
to manage this catastrophic disease but also may be faced with AMI as
a consequence of other illnesses that they treat.
