Abstract/OtherAbstract:
Routine cerebral ultrasound examinations of the neonatal brain often show the choroid plexus to be enlarged, without revealing any other structural pathology. This enlargement might be due to congestion of the choroid plexus as a result of increased cerebral blood flow, due to increased partial pressure of carbon dioxide, amongst other factors. In this exploratory study, 76 cerebral ultrasound examinations, performed on 42 newborn infants within the first 10 days after birth, were analysed retrospectively. The ultrasonograms were classified into three diagnostic groups: normal, congestion of the choroid plexus and haemorrhage. The relationship between the diagnostic groups and the estimated mean arterial partial pressure of carbon dioxide (P(a)CO(2)) was investigated. In the first three postnatal days, the estimated mean P(a)CO(2) in the normal group was significantly lower than in the congestion group (P<0.001). No significant differences were found between the P(a)CO(2) in the congestion and the haemorrhage groups. The findings might support a relation between a high P(a)CO(2) and congestion of the choroid plexus in the first three postnatal days and might be a sign of increased risk for a periventricular haemorrhage.
