[Subclavian steal syndrome examined by transcranial Doppler sonography]

Authors are presenting the diagnostic problems of subclavian steal syndrome, they are using the transcranial Doppler sonography (TCD). This method completes the traditional sonographic possibilities. With help of specific signs there is the possibility to confirm the clinical diagnosis and we can reach data from the dynamic of cerebral circulation and the situation of the circulation of the intracerebral collateral system, too. Authors briefly summarise the clinical signs of subclavian steal syndrome and the verification of the signs and the opinions, concerning the angiographic and sonographic method and the possibilities of surgical treatment.
