paradoxical embolism due to persistent foramen ovale; a case report
Authors
abstract
the mean percentage of cryptogenic strokes among ischemic strokes is 31%, of which one-third may be associated with patent foramen ovale. the foramen ovale is required for blood flow through the fetal atrial septum. it is formed as of the fourth week of gestation, and this leads to right-left interatrial shunt that allows the passage of oxygenated blood to systemic circulation. in 75% of cases, its closure is complete by 2 years of age, but it may persist in 25% of patients. we present the case of a patient with paradoxical embolism in the lower extremities and ischemic stroke in the clinical context of a patent foramen ovale.

Paradoxical Embolism due to Persistent Foramen Ovale; a Case Report

It is formed as of the fourth week of gestation, and this leads to right-left interatrial shunt that allows the passage of oxygenated blood to systemic circulation. In 75% of cases,...
full textPatent foramen ovale: is stroke due to paradoxical embolism?
BACKGROUND AND PURPOSE A patent foramen ovale has been reported to be significantly more frequent in young stroke patients than in matched control subjects, and paradoxical embolism has been suggested as the main mechanism of stroke in this situation. The present study was designed to test this hypothesis. METHODS Sixty-eight consecutive patients under 55 years of age presenting with an ische...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-009818 DESCRIPTION A 32-year-old man recently had a right-sided hemiparesis; a head CT scan revealed left middle cerebral artery (MCA) territory infarct. The patient was haemodynamically stable, with no clinical evidence of deep venous thrombosis (DVT) and was...

Introductioi Paradoxical embolism is generally regarded as a rare event but the 2 cases described presented to a single unit within 6 months. This supports the view of Meister et al. (1972) that paradoxical embolism may be far more common than is frequently thought. The second case demonstrates the value of a high index of suspicion in making a clinical diagnosis so that appropriate and early t...

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. It is a relatively rare phenomenon, representing about 2% of all cases of arterial embolism. We report a case of a 79-years-old woman admitted to hospital because of dyspnea and lower left limb pain. CT scan revealed multi...

We have tested the hypothesis that anxiousness and pain may be the main reasons for hormonal response to cataract operation. Regarding anxiousness we compared local anaesthesia alone or under sedation with propofol concerning their effec...
