Abstract

We recorded cerebral artery flow velocities (CAFV) in two neonates with cerebral infarction, using transcranial Doppler sonography (TCD). Cerebral infarction was diagnosed by brain imaging. The arteries investigated were the middle cerebral artery (MCA), the internal carotid artery (ICA) and the anterior cerebral artery (ACA).

The whole territory of right MCA was involved. A decrease in CAFV was noted in MCA and ICA of the affected side. Furthermore, early recordings of CAFV allowed us to distinguish perinatal infarction from antenatal infarction: in the former, Doppler signal was completely absent during the first days of life whereas in the latter, Doppler signal was reduced but present. The process of recanalization could be followed. The asymmetry of CAFV recorded in the neonatal period seems to persist definitively at least in MCA. These Doppler data correlate well with the evolutive stages of cerebral infarction shown by brain imaging.

Beside US, CT and MRI scans, TCD may be a useful adjunct for identifying and following infants with suspected occlusion of major cerebral vessels.
