Causes
Ischemic colitis is often classified according to the underlying cause. Non-occlusive ischemia develops because of low blood pressure or constriction of the vessels feeding the colon; occlusive ischemia indicates that a blood clot or other blockage has cut off blood flow to the colon.
Non-occlusive ischemia
In hemodynamically unstable patients (i.e. shock patients) the mesenteric perfusion may be compromised.
Occlusive ischemia
Occlusive is ischemia is due to either:
1. Obstructive Atherosclerotic Disease
2. Thromboembolism:
- Most commonly the embolism is due to atrial fibrillation
- Valvular heart disease
- Myocardial infarction
- Cardiomyopathy
