Abstract

Transcranial color Doppler sonography (TCCD) is a useful tool for intracranial investigation. Using TCCD to calculate total cerebral blood flow volume (TCBFV) can be a useful indicator for intracranial hemodynamic status. We performed a series study of TCCD on 60 healthy kindergarten students. Peak-systolic, end-diastolic, and mean blood velocities of major cerebral arteries, and depth of flow waves were measured. We also collected Gosling pulsatile index (PI) and Pourcelot resistance index (RI) of the arteries. TCBFV was calculated from the mean blood flood velocity and vessel chamber size of the internal carotid artery (ICA) and basilar artery (BA). Fifty children completed the examinations. The TCBFV was 1538+/-416 ml/min with mean cerebral blood flow volume of 571+/-241 ml/min for the ICA system and 983+/-343 ml/min for the BA system. PI, RI, and the velocities of A1, A2, M1, M2, BA, ICA, and TCBFV were not significantly different between girls and boys in this age group. In this study, we used TCCD to determine the normal data of main cerebral arteries and TCBFV of pre-school children in Taiwan. The reference data of velocities and other parameters of main cerebral arteries from our study may serve as a guide for additional pediatric cerebral hemodynamic studies.
