Background
- Defined as a reduction of blood to the small and/or large intestines. May be acute or chronic.
Intestinal Ischemic Disorder Types
- Ischemic colitis
- Accounts for 80-85% of intestinal ischemia
- Due to non-occlusive disease with decreased blood flow to the colon.
- Causes decreased perfusion leading to sub-mucosal or mucosal ischemia only.
- Typical to the "watershed areas" of the colon (Splenic flexure or Sigmoid)
- Acute mesenteric ischemia
- Due to complete occlusion of mesenteric vessels
- Complete transmural ischemia
- Mesenteric venous thrombosis
- Chronic mesenteric ischemia ("intestinal angina")
