  • Title: Paradoxical embolization via a patent foramen ovale following acute pulmonary embolism.
    Author: Thomas DV, Bynevelt M, Price R.
    Journal: Australas Radiol; 2005 Dec; 49(6):501-4. PubMed ID: 16351617.
    Abstract:
    The foramen ovale is usually obliterated following establishment of the adult circulation but remains patent in 25% of individuals. This potential communication between the venous and arterial circulations can allow thromboembolic material to bypass the lungs and enter the systemic circulation. We report two cases of paradoxical embolization through a patent foramen ovale following acute large pulmonary embolism (PE) and discuss the factors that predispose to paradoxical embolization following PE.
