The assessment of the presence of the intracranial hypertension by means of the compression Doppler-ultrasound in posthaemorhagic newborns' hydrocephalu
Aim. In our study we focused on the ultrasound diagnostics of intracranial hypertension in neonates with diagnosis of posthemorrhagic hydrocephalus (PHH). We wanted to try and verify the method of "pressure provocation test". When performing this test, the great fonticulus is compressed by ultrasound probe and simultaneously systolic and diastolic velocities are being measured in the internal genu of the anterior cerebral artery with resisistive index calculation. Pressure on fonticulus during examination shows us the reserve capacity of liquor spaces and the response in cerebral arteries blood flow. The primary objective was to verify, if the basic and compressive resistive index correlates with the presence and eventually with the severity of intracranial hypertension. The secondary objective was to find relationship between the degree of intracranial hypertension and the diameter of cerebral ventricles, to asses the rapidity of PHH developement and to find out, in which period is PHH the most common. Method. In years 1999 - 2008, 52 children with diagnosis of posthemorrhagic hydrocephalus were examined in our department. The average birth weight in children with PHH was 1436 g (550 - 4090 g, median 1150 g). The average age was 29,6 weeks (24 - 41 weeks, median 28 weeks). Totally, 73 % of children...
