[Transcranial dopplerography in the combination with echopulsography in the assessment of intracranial and cerebral perfusion pressure in patients with intracranial hemorrhages].

OBJECTIVE
To study the possibilities of common ultrasound diagnostic methods in the evaluation of intracranial pressure (ICP) and central perfusion pressure (CPP) and to search for the ways of increasing the accuracy of these methods.


MATERIAL AND METHODS
Thirty-eight patients, aged 28-66 years admitted to a neuroreanimation department of a hospital due to acute intracranial vascular and traumatic hemorrhages were examined. An instrumental study included transcranial dopplerography (TCDG) and digital echoencephalography. Accuracy of measurement was evaluated for ICP and CPP in clinical conditions.


RESULTS
The data obtained confirm the possibility of quantitative assessment of ICP and CPP using TCDG. We suggest a new formula for more precise calculation of CPP.


CONCLUSION
The complex use of noninvasive ultrasound methods allow in most cases to measure with acceptable accuracy and assess the degree of intensity of ICP and CPP changes at the acute stage of intracranial hemorrhages.
