What are the different varieties of ischemic bowel disease?
Ischemic bowel disease can be sorted into various categories based on the vascular component affected (arterial or venous), the duration of reduction of blood flow through the vessel (acute or chronic), and the cause of the reduction in flow (occlusive or nonocclusive).
It can also be sorted into clinical entities:
- • Acute mesenteric ischemia (AMI), usually due to emboli, thrombi, or vasoconstriction
- • Chronic mesenteric ischemia, usually a result of atherosclerotic disease
- • Colonic ischemia, most often secondary to transient hypoperfusion
