[The use of doppler color ultrasonography in the evaluation of superior sagittal sinus patency in operations for parasagittal meningiomas].

The authors present the possibility of replacement of invasive angiography by non-invasive, safer, more accurate USG-colour Doppler performed during the operation to estimate the permeability of superior sagittali sinus in falx meningioma cases. Based on the presented case they discuss the advantages of this method in relation to angiography routinely performed so far.
