Abstract

Transcranial Doppler (TCD) is a noninvasive, fast and exact diagnostic tool for the evaluation of cerebral hemodynamics, providing numerous information on cerebrovascular state of the patient. The major advantage of TCD application is in revealing patients with acute vascular pathology: intracranial blood vessel stenosis, AV malformations, angiomas, brain death, hemodynamic evaluation of tandem lesions, collateral capacity, monitoring of vasospasm, brain edema and intraoperative monitoring, classification of stroke, and early detection and prevention of stroke. Recent TCD modalities enable detection of cerebral microemboli, estimation of cerebral vasoreactivity, and cerebral autoregulation by analyzing cerebral microcirculatory responses after stimulation tests such as CO2 reactivity, acetazolamide or functional tests by cognitive tasks. TCD is an objective and easy to manage diagnostic tool for the assessment of cerebral hemodynamics, irreplaceable method in intensive care units, and very helpful in outpatient screening for cerebrovascular diseases.
