Abstract:
Objective To evaluate the diagnostic value of transcranial color duplex sonography for vertebrobasilar arterial insufficiency (VBI). Methods Transcranial color duplex sonography was performed on 30 healthy controls and 30 VBI patients confirmed clinically to examine the flow velocities and wave form parameters of the main supra and infra tentorial basal cerebral arteries. The anterior, middle, and posterior cerebral arteries on either side of the cranium and the vertebrobasilar system were observed using a 2.0 MHz transducer of a computed sonographic system. Results The vertebral artery system resistance index and pulsitive index were significantly higher in VBI patients than those in the controls ( P
