“…In the neonate, venous thrombosis is often unrecognized, especially because of its clinical latency. A systematic color Doppler evaluation during every neonatal brain sonography could assess the true incidence of this disease [21,22]. Color Doppler is obviously required in cases of unexplained seizures.…”

We know that many cerebral lesions are of circulatory origin and it is now important to study cerebral hemodynamics by pulsed and color Doppler ultrasonography. The revolution in the imaging of vascular physiology, the diagnosis, and the prognostic evaluation of vascular disease are not based on morphological sonographic studies but on the Doppler techniques that can display cerebral vessels in the neonate. The results of the hemodynamic investigation in 491 newborns aged from 32 weeks of gestation to 9 months by means of pulsed and color Doppler are reported. Normal values of the resistive index, peak systolic, end-diastolic, and time-averaged velocities in seven different vessels are determined. Some pathological examples are presented. Doppler techniques play a major role in the diagnosis, follow-up, and management of brain damage, whether ischemo-hemorrhagic, infectious, or developmental or tumoral, and of pericerebral collections.

“…The elevated venous pressure is regarded to be a cardinal trait of these malformations and the main cause for the development of hydrocephalus [7,17,20]. The venous hypertension is transmitted via the dural sinuses to the cortical and medullary veins of the brain with subsequent difficulty for the CSF to enter from the subarachnoid space into the venous compartment.…”

Vein of Galen vascular malformations in infants: clinical, radiological and therapeutic aspect

A series of 14 vein of Galen vascular malformations diagnosed in the pediatric populations and treated at the Hospital for Sick Children-Necker, Paris, between 1988 and 1994 is presented. Five of the patients were diagnosed in the neonatal period, of whom 4 presented with life-threatening, intractable cardiac decompensation and high-flow arteriovenous fistulae. Embolization was performed on vital indications in 4 patients during the first week after birth. One embolization failed with fatal outcome. Of the 3 who were embolized, 2 succumbed within 1 week and 1 survived with marked improvement of cardiac symptoms. The older children presented with hydrocephalus and neurologic symptoms. The 10 patients older than 1 year were embolized. These procedures were successful in 90 %, with hemodynamic stabilization and improvement of clinical symptoms. In this group the mortality rate was 10 %. The total mortality rate was 29 %. Hydrocephalus was secondary to a compression of the Sylvian aqueduct in 44 % of cases. Five patients had ventricular drainage before embolization followed by a staged elective embolization. Transarterial embolizations were performed in 11 patients, whereas 2 patients were embolized via the transvenous route.

“…Venous waveforms in the superior sagittal sinus may be continuous and monophasic or may fluctuate in synchronicity with arterial pulsations (Figure 5.b.). Intracranial venous flow velocities gradually increase after birth (Dean & Taylor, 1995). The mean velocity in the superior sagittal sinus usually ranges between 8 and 12 cm/s in neonates.…”

“…Color Doppler imaging is also useful in defining the limit of the arterial system within the subarachnoid space. This helps differentiate fluid in the subdural space from adhesions within the arachnoid space, as the arterial system is confined to the subarachnoid space (Chavhan et al, 2008;Dean & Taylor, 1995) …”
