[The application of transcranial doppler sonography in the evaluation of cerebral flow disturbances after head trauma]. / Zastosowanie przezczaszkowej ultrasonografii dopplerowskiej do oceny zaburzen mózgowego przeplywu naczyniowego po urazach czaszkowo-mózgowych.

Several types of cerebral blood flow disturbances, resulting from head trauma are discussed. Application of Transcranial Doppler Sonography in diagnosing of posttraumatic cerebral vasospasm and cerebral hyperaemia, increased intracranial pressure, autoregulation disturbances, and brain death is described. Clinical examples of isolated cerebral blood flow disturbances, and several types of their co-existence are given. Special attention was paid to the noninvasiveness, repetitiveness, and relative ease of use of the technique. Transcranial Doppler examination can be especially useful in diagnosis and monitoring of different cerebral blood flow disturbances, which is especially important in therapy of brain trauma patients.
