J. Schweizer et al., FIRST RESULTS OF COLOR DUPLEX SONOGRAPHY AND COLOR-CODED INTRACRANIALDUPLEX SONOGRAPHY IN PATIENTS WITH IMPAIRED INNER-EAR FUNCTION, VASA, 24(3), 1995, pp. 238-240
A prospective investigation of 98 patients with acute loss of inner ea
r function showed that such patients display changes in the pulsatilit
y of the basilar artery; however, the differences can be appreciated o
nly by comparison with control sonograms during the course of the dise
ase. Patients with sudden deafness or sudden loss of equilibrium gener
ally showed unremarkable findings on duplex sonography of the cervical
portions of vessels supplying the brain.
