Zusammenfassung
Background: Contrast-enhanced transcranial Doppler ultrasonography is a sensitive non-invasive method for detecting a patent foramen ovale (PFO). The association between the clinical finding of a suchlike detected right-to-left shunt and ischemic stroke is still a matter of debate. We aimed to investigate the potential causal relationship in a population of unselected stroke patients. Methods: The records of 764 consecutive patients who were investigated at our institution were reviewed. For microembolic monitoring, a 2MHz pulse-wave transcranial Doppler device was used for simultaneous insonation of both middle…
