Abstract: Infective endocarditis is a severe infectious disease that, in addition to cardiac complications such as heart failure and arrhythmias caused by valve damage, may also lead to extracardiac complications such as septic embolization, metastatic abscesses, and mycotic aneurysms. Here, we report a rare case of splenic infarction resulting from infective endocarditis, subsequently leading to the development of a splenic artery aneurysm three weeks post-surgery confirmed both by CTA and DSA. Following arterial embolization of the aneurysm, the patient eventually recovered completely.

Keywords: infective endocarditis, splenic infarction, pseudoaneurysm
