Can ischemia be isolated to the colon?
- Ischemic colitis is the most common form of non-occlusive intestinal ischemia occurring in older adult patients with impaired cardiac output via a nonocclusive mechanism.
- In younger patients, however, the cause can be occlusive (sickle cell disease, hypercoagulable states) or nonocclusive (cocaine use, vasculitis, long-distance running).
