Abstract
In patients with cerebral ischemia of unknown origin, paradoxical embolism must be considered as one of the possible causes, if there is an abnormal right-to- left shunt. The most likely site of transmission is a persisting patent foramen ovale (PFO), which is found in approximately 30% of adult persons in autopsy studies. Using transcranial Doppler sonography (TCD) and an agitated saline solution as an inexpensive and readily available contrast medium, probably all clinically important right-to-left shunts can be detected. In our department we examined 215 patients within the last 5 years, 30% of which had an abnormal right-to-left shunt with insignificant difference between 10 and 69 years of age.
