The incidence of ischemic colitis is at least 16 per 100 000 people / year; however, the true incidence is likely greater, as many people may not recognize the transient symptoms of ischemic colitis. It is believed that colonic ischemia may be more prevalent in women.
Typical presenting symptoms include lower abdominal pain and bloody diarrhea. The presentation can be acute or chronic (more often involving the rectum). Risk factors for the development of ischemic colitis include smoking, atherosclerosis, aortoiliac surgery, myocardial infarction, hemodialysis, and hypercoagulable state.
