Trombo a través de foramen oval permeable: embolia paradojal cerebral y factores de alto riesgo de recurrencia. Caso clínico / Paradoxical embolism due to a persistent patent foramen ovale: report of one case

Abstract: Patent Foramen Ovale (PFO) is one of the most frequent congenital defects in adults. Its prevalence in middle-aged adults is close to 25-30% and may cause paradoxical embolic phenomena. We report a 45 years old male admitted for an ischemic stroke with an occlusion of the left terminal internal carotid artery. A thrombectomy was performed. Searching for possible sources of emboli, a patent foramen ovale was detected in an echocardiography, with an hypoechogenic examination image passing through it. Anticoagulant therapy was started and the patient had an uneventful evolution.
