“…As such, after the discussion with a neurologist, we administrated a half dose of rtPA, and this modified thrombolytic therapy enabled the patient to make a good recovery from hemodynamic instability. In literature, there are number of case reports presenting similar situations 5)11). However, our case was notably different from these cases, both in terms of the timing of the stroke and the treatment modality.…”

A paradoxical embolism is defined as a systemic arterial embolism requiring the passage of a venous thrombus into the arterial circulatory system through a right-to-left shunt, and is commonly related to patent foramen ovale (PFO). However, coexisting pulmonary embolisms, deep vein thromboses (DVT), and multipe systemic arterial embolisms, associated with PFO, are rare. Here, we report a patient who had a cryptogenic ischemic stroke, associated with PFO, which is complicated with a massive pulmonary thromboembolism, DVT, and renal infarctions, and subsequently, the patient was treated using a thrombolytic therapy.

“…There are case reports or case series reported in which intracardiac right-sided thrombus were detected incidentally or during acute PTE [2,3]. The coincidence of PTE and a thrombus entrapped in the patent foramen ovale (PFO) is also reported with in few case reports [4,5]. In these cases generally a paradoxical embolus was also accompanied with the pulmonary embolus.…”

Pulmonary embolus sourced by right atrial thrombus trapped in a patent foramen ovale is an unusual, rare condition. Thus in suspicion of massive pulmonary thromboembolus, echocardiographic examination carries great importance evaluate right ventricular functions and diagnose right sided intracardiac thrombus. We report a 76-year-old female with massive pulmonary embolism caused by a gigantic thrombus trapped in a patent foramen ovale. The echocardiography was the diagnostic procedure to display the source of the thromboembolism and urgent cardiac surgery was successful and life-saving treatment in this case.

“…La mortalidad del síndrome de embolismo paradójico puede ser alta cuando se asocia una afectación sistémica y neurológica o pulmonar (10). Por ello el tratamiento debe incluir la prevención de nuevas embolias, que como en nuestro caso se soluciona cerrando el cortocircuito existente.…”

RESUMENEl infarto cerebral durante el embarazo o puerperio es una complicación grave que causa alta morbimortalidad materna. Presentamos el caso de una mujer previamente sana, de 32 años de edad, que sufrió embolismo cerebral posparto. La ecocardiografía confirma la presencia de foramen oval permeable, que puede ser causa de embolismo paradójico, causando un accidente vascular cerebral transitorio o infarto. Para prevenir episodios recurrentes de embolismo cerebral durante el embarazo, parto o puerperio, se realizó el cierre intervencional del foramen oval sin complicaciones. PALABRAS CLAVE: Embolismo paradójico, foramen oval permeable, ictus en el posparto SUMMARYStroke during pregnancy and puerperium is a severe complication that causes high morbidity and mortality. We report a case of previously healthy, 32 year old woman, who suffered cerebral embolism after delivery. Echocardiography confirmed the patent foramen ovale. Patent foramen ovale may be a mechanism of paradoxical embolism causing a transient ischemic attack or stroke. To prevent recurrent cerebral embolism during pregnancy, delivery and puerpuerium, interventional closure of the patent foramen ovale was performed. The postinterventional course was uneventful. KEY WORDS: Paradoxical embolism, patent foramen ovale, postpartum period stroke INTRODUCCIÓNEl ictus isquémico durante el embarazo o puerperio es una complicación severa con alto riesgo de morbimortalidad materna. Uno de los factores de riesgo es la persistencia de la permeabilidad del foramen oval que puede producir embolismo paradójico (1).El embolismo paradójico es una causa rara de embolia, que ocurre cuando se produce el paso de un trombo desde el sistema venoso o desde las cavidades cardiacas derechas a la circulación arterial, sin pasar por el filtro capilar pulmonar, a través de un cortocircuito derecha-izquierda (2).Presentamos un caso con sospecha clínica de ictus isquémico confirmado posteriormente por RMN y angioRMN, secundario a un trombo venoso localizado en miembro inferior (área íleo-femoral) diagnosticada por Eco-Doppler y secundario a la presencia de un foramen ovale permeable objetivado posteriormente en una ecografía transesofá-gica. 339 REV CHIL OBSTET GINECOL 2010; 75(5): 339 -342
