Background: Solid organ infarctions are uncommon causes of abdominal or flank pain. This could partially be due to under-diagnosis. Several causes, including emboli in a setting of atrial fibrillation (afib) or left ventricular thrombus formation, vasculitis, local vascular compression, underlying malignancies, infections, vascular dissection and substance abuse may be responsible.
Aim: Despite extensive diagnostic work up, the exact source, or the reason for the emboli remains unknown. Small studies have highlighted that afib is one possible cause for emboli, similar to the mechanism of stroke. Determining the cause, when possible, may help initiate appropriate treatment to avoid future events that can lead to a devastating stroke, myocardial infarction or organ loss. We seek to investigate the cause of the infarct in all these cases.
Design: Retrospective study
Method: Case review including diagnostic tests and literature review.
Conclusion: No clear source was identified. Intermittent afib could be one source, but due to lack of long term rhythm monitoring, no definitive conclusion could be made.
