Paradoxical Embolism due to Persistent Foramen Ovale; a Case Report
نویسندگان
چکیده
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.

Pulmonary embolism and concomitant paradoxical embolism. A case report.
Although patent foramen ovale is a relatively common disease, the presence of paradoxical embolism is a rare clinical condition, representing less than 2% of arterial ischemias. We report the case of a 55-year-old male diagnosed with massive pulmonary embolism and paradoxical embolism in the right arm, secondary to patent foramen ovale. We also highlight some uncertainties in the diagnosis and ...
متن کاملTriple percutaneous patent foramen ovale closure
Percutaneous patent foramen ovale (PFO) closure is mainly performed for secondary prevention of presumed paradoxical embolism. Since a residual shunt has been associated with recurrent events, complete PFO closure is desirable. We report the first case of ultimately successful percutaneous PFO closure using successively 3 Amplatzer PFO devices.

Air embolism is a rare complication of percutaneous nephrolithotomy. Patent foramen ovale, which is necessary in fetal circulation, is a potential route for emboli arising from the venous system to enter the systemic arterial circulation, resulting in paradoxical air embolism syndrome. A case of paradoxical air embolism during percutaneous nephrolithotomy is presented. To our knowledge, this is...

متن کاملA New Method for Patent Foramen Ovale Closure: Delivering Sheath Over Coronary Sinus Catheter into Left Atrium
Patent foramen ovale (PFO) is a frequent condition. It usually does not pose any threat to life, but in certain circumstances, it can open and serve as a conduit for thrombi causing paradoxical embolism. Herein, we report a case of PFO in a patient with ischemic cerebrovascular accident, due to paradoxical embolism, which could not be passed via general practice; hence it was crossed with coron...
