The terms “giant-cell arteritis” and “temporal arteritis” are sometimes used interchangeably, because of the frequent involvement of the temporal artery. In spite of the advances, we still need to research too much about the syndrome’s etiopathogenesis, because some data are still uncertain. Unilateral temporal artery biopsy was then performed in patients with suspected GCA, which was directed to a particular arterial segment in case a halo was detected in CDS.

The present study was designed to specifically examine the diagnostic value of CDS with respect to common problems in the approach of a patient with clinically suspected GCA, for whom the decision for immediate treatment is imperative. Segmental increase of blood-flow velocity, perhaps with waveforms indicating turbulence, was classified as stenosis in case it could not be attributed to other abnormalities that is, artery kinking tdmporal atherosclerotic lesions.
