Risks of tumor embolization in the presence of an unrecognized patent foramen ovale: case report.
A patent foramen ovale (PFO) is a fairly common septal defect in the general population. Paradoxical embolization through a PFO is a known cause of stroke. Preprocedural recognition of a PFO in a patient undergoing particulate arterial embolization can help reduce the risk of cerebral infarction.
