Ischemia and necrosis of part or all of the spleen resulting from compromise of blood supply resulting from arterial or venous occlusion.
Comment:
Splenic infarction may be global or involve a segment of the spleen depending on which vessel is occluded. Typical presentation includes left sided abdominal pain in a person with an underlying hematologic disorder, hypercoagulable state, blood-borne malignancy, blunt abdominal trauma, or embolic illness.
