Patent Foramen Ovale Closure for Splenic Infarction: An Unusual Presentation and an Unusual Indication

Background. Splenic infarction is a rare clinical condition. It is generally attributed to hematologic, vascular, cardioembolic, and infectious diseases or trauma. Case Presentation. We describe a rare case in an otherwise asymptomatic 41-year-old overweight woman with acute abdominal pain. Imaging work-up revealed splenic infarction. Common etiologies were excluded. A transesophageal echocardiography (TEE) revealed a patent foramen ovale (PFO). The patient was sent to closure with good outcome. Conclusion. Paradoxical embolism due to PFO can be a cause of splenic infarction, and its investigation and subsequent closure may be considered when there are no other causative disorders.
