BLOOD FLOW VELOCITY (BFV) IN THE STRIATE ARTERIES OF BASAL GANGLIA (SABC) WITH HYPERECHOGENICITIES IN THEIR WALL. A COLOUR DOPPLER FLOW IMAGING STUDY (CDI)

Abstract

Hyperechogenicities were demonstrated to be allocated along SABG in 35 babies by CDI. The etiology and pathogenesis of this finding remains unclear. We speculated that this pathology may cause pathological BFV. Thus, the aim of the study was to investigate whether the BFV in the involved arteries was altered. Peak systolic flow velocity (PSFV), end diastolic flow velocity (EDFV), temporal mean flow velocity (TMFV), Pulsatility Index of Gosling (PI) and Resistance Index of Pourcelot (RI) were determined. Patients were stable and free of any of the conditions that are known to alter the BFV. 20 healthy neonates formed the control group. The results were:

Conclusion: PI and RI were low in both groups suggesting a decrease in pulsatile flow in these arteries. This type of lesion does not appear to alter the regional blood flow at least in stable conditions.
