    Notes: Abstract Intracranial pressure and cerebral blood flow velocity were recorded in term healthy neonates during the first 3 days of life using non-invasive methods (LADD-fontanometry and cw-Doppler sonography). Intracranial pressure increased from 4.0±2.7 cm H2O to 5.8±2.7 cm H2O and maximal cerebral blood flow velocity in the anterior cerebral artery (ACA) increased from 33 cm/s to 58 cm/s as calculated from a Doppler shift of 0.63 to 1.10 kHz and vascular resistance decreased between the 1st and 3rd day of life. These alterations could not be demonstrated in the femoral artery. This is in accordance with other registrations obtained by different methods and under various conditions. They allow an explanation of some well known physiological phenomena like alterations of cranial volume and the structure of the bony skull in the first days of life. Furthermore, these physiological variations may have implications for the origin of cerebral damage during the perinatal period, especially of hypoxic-ischaemic encephalopathies.

    Cerebral infarction in term neonates: diagnosis by cerebral ultrasound (1986)
    Springer

    Notes: Abstract Cranial ultrasound (US) through the newborn's open fontanelle can diagnose not only intracerebral hemorrhages but also diffuse and localized hypoxic-ischemic encephalopathies. Sonographically, it was possible to distinguish between different courses of cerebral ischemia in seven neonates: (1) ischemic infarction, usually in the area of the middle cerebral artery; (2) borderline infarction; (3) transient ischemia. The patients showed lateralized seizures during the first days of life with a corresponding focus in the electroencephalogram (EEG). Computed tomography showed areas of partially reduced density corresponding to the regions of increased echogenicity in ultrasound. The course was various; prognosis was good except in one patient. Etiologically, embolism, thromboses or hypoxemia were responsible for cerebral infarction. In some cases secondary bleeding ensued. The prognostic value of cerebral lesions was dependent on the involved area, gestational age, and any concurrent hypoxic cerebral damage.
