title: Paradoxical arterial embolism involving both upper extremities in a patient with pulmonary embolism and a patent foramen ovale.
abstract: Paradoxical embolization is an uncommon but devastating complication of pulmonary embolism (PE). Awareness of this complication with prompt recognition and treatment could serve to preclude significant disability and death. Described is a case of PE associated with paradoxical embolism to the arteries of both upper extremities. While patent foramen ovale (PFO) is common, paradoxical embolism is infrequent but can involve almost any artery of the body. Discussed are the risk factors, clinical presentations, and diagnostic and treatment options for paradoxical embolism. Awareness of the potential for paradoxical embolization in patients with PE is essential to its prompt recognition and treatment.
