[The use of TCD in intensive care and for identification of complications in subarachnoid hemorrhage ].
Transcranial Doppler (TCD) is at present the only exam to allow non-invasive, bedside monitoring of cerebral vasospasm after SAH. The high temporal resolution of this technique enables detection of fast flow-velocity changes occurring in intracranial arteries, as well as evaluation of vasomotive reserve and strength of autoregulation. TCD results concerning cerebral vasospasm evaluation are comparable to those obtained in angiographic studies; however the correlation between TCD data and clinical status is not always so strict. This difference could be explained by the fact that TCD measures flow velocity and not flow in intracranial vessels.
