Thrombus enclavé dans le foramen ovale perméable : à propos d’un cas révélé par une embolie pulmonaire au CHU de Libreville

Abstract

The patent foramen ovale is common in the general population. It is often encountered during paradoxical embolisms. During a pulmonary embolism, its presence is a poor prognosis. The discovery of an enclosed thrombus in this area is rare. We report a case of an enclaved thrombus in the patent foramen ovale discovered during a transthoracic echocardiography indicated in the presence of a suspected pulmonary embolism in a pregnant woman. This patient presented with hemodynamic instability, the evolution of which was favorable after thrombolysis with tenecteplase. In the absence of consensus on the management of thrombi trapped in the patent foramen ovale, the track of a better prognosis according to the class of thrombolytics used should be studied.
