Splenic Infarction

Splenic infarction is ischemic necrosis of splenic tissue caused by occlusion of the splenic artery or its branches, usually from embolus (endocarditis), thrombosis, sickle-cell disease, hypercoagulable state, or infiltrative disease. Often presents with left-upper-quadrant pain and fever; small infarcts may be asymptomatic.

Common Symptoms

Left-upper-quadrant pain; fever; pleuritic pain; nausea

Causes and Pathogenesis

Arterial occlusion by embolus/thrombosis leads to ischemic coagulative necrosis of splenic parenchyma.

Treatment

Supportive care; analgesia; treat underlying cause (anticoagulation, endocarditis); surgery if rupture/abscess

Preventive Measures

Control embolic sources; anticoagulate as indicated; treat hypercoagulable states.
