[Diagnosis of carotid-cavernous fistula using color Doppler ultrasonography].

The authors evaluated orbital haemodynamics by Colour Doppler flow Information (CDFI), in 4 cases of carotid-venous fistulas (CCF). Significant changes were demonstrated only in the superior orbital vein (SOV) = 1. Changing of course blood flowing-biodirect (as an alternating orthograde and retrograde) blood flow, or constant retrograde blood flow in SOV, independent from Valsalva manoeuver. 2. Pulsating SOV, in spectral analyse as a retrograde blood flow is synchroned with cordial rhythm on electrocardiography record. 3. Dilatation of color echo of the VOS is a nonconstant sign of CCF.
