Ischemic bowel is a catastrophic condition which is difficult to diagnose with certainty and is associated with significant morbidity and mortality even in those cases where the diagnosis was established and the treatment was instituted promptly. One should maintain a high index of suspicion for this disease especially if a patient complains of pain which is out of proportion to the physical findings, if the pain is not relieved by narcotics, and if the patient cannot find a comfortable position. One should not wait for changes in the physical exam or lab results to seriously consider this entity, at this point the opportunity for bowel salvage may be lost. The clinical presentation depends on the exact cause of the ischemic changes; this chapter will discuss arterial embolism, arterial thrombosis, venous thrombosis, and non-occlusive mesenteric ischemia.
