Mesentric ischemia (MI) is classied into various subdivisions based on the difference in pathogenesis and treatment of each type. MI is primarily classified into acute and chronic, on the basis of severity; occlusive and non occlusive based on their pathophysiology.


  • Based on the severity mesenteric ischemia is classified as either acute or chronic.[1][2][3][4]
    • Acute mesenteric ischemia
    • Chronic mesenteric ischemia
  • Acute mesenteric ischemia is further classifed into occlusive and non-occlusive subtypes,
  • Occlusive MI is further classified into three more subclasses.
  • Occlusive mesenteric ischemia: [5][6]
    • Mesenteric arterial embolism
    • Mesenteric arterial thrombosis
    • Mesenteric venous thrombosis
  • Non-occlusive mesenteric ischemia[7]
