Topics Covered
- Ischemic disease of the gastrointestinal tract manifests a spectrum of injury that includes ischemic colitis, acute mesenteric ischemia, focal segmental ischemia and intestinal angina, each with its own presentations, management strategies, and outcomes
- This lecture will review fundamental s of each of the types of ischemic damage to the gastrointestinal tract
