Descriptor English: Embolism, Paradoxical
Descriptor Spanish: Embolia Paradójica
Descriptor embolia paradójica
Scope note: Bloqueo de una arteria como consecuencia del paso de un coágulo (TROMBO) desde el circuito venoso al circuito arterial sin pasar por el pulmón, que actua como un filtro para impedir que los coágulos de sangre pasen al circuito arterial. Los embolismos paradójicos se producen cuando existe un defecto que permite el paso de un coágulo directamente desde las cavidades derechas a las cavidades izquierdas del corazón, como es el caso de DEFECTOS DEL TABIQUE AURICULAR o AGUJERO OVAL abierto. Una vez alcanzada la circulación arterial, el coágulo llega al encéfalo, bloqueando una arteria y causando un ICTUS.

Scope note: Blockage of an artery due to passage of a clot (THROMBUS) from a systemic vein to a systemic artery without its passing through the lung which acts as a filter to remove blood clots from entering the arterial circulation. Paradoxical embolism occurs when there is a defect that allows a clot to cross directly from the right to the left side of the heart as in the cases of ATRIAL SEPTAL DEFECTS or open FORAMEN OVALE. Once in the arterial circulation, a clot can travel to the brain, block an artery, and cause a STROKE.
