Abstract

Doppler transcranial ultrasonography (TCD) is a very useful method for the identification and monitoring of ongoing disturbed haemodynamics of brain circulation. The method is noninvasive, relatively cheap and may be applied at the bedside whatever the patient's condition. It requires considerable experience and skill on behalf of the examiner, however. TCD is widely used in the monitoring of patients with serious cranial-cerebral injuries. It allows the examiner to monitor a whole complex of patophysiological changes resulting from brain injury. The major ones include vascular contraction, congestion, degree of maintenance of cerebral vascular self-regulation and, indirectly, changes in intracranial pressure and checked cerebral blood flow. Daily TCD monitoring in brain injury patients are very helpful for correct evaluation and differentiation of type of disturbance of brain circulation haemodynamics and the monitoring of treatment efficacy. The most recent findings in this domain are reviewed.
