THE TRANSOCCIPITAL APPROACH FOR TRANSCRANIAL DOPPLER ULTRASONOGRAPHY OF THE VERTEBROBASILAR CIRCULATION

With the transoccipital paramedian approach for transcranial Doppler e xamination of the vertebrobasilar circulation, a complete examination of the intracranial vertebral arteries und basilar artery is possible without moving the patient from the supine position; this may be of va lue in intensive care conditions. Blood flow velocity and flow directi on in these vessels are registered through the occipital bone at relat ively more superficial levels, and identification of right and left ve rtebral arteries usually represents no problem.
