Results
The cross-sectional area of cerebral aqueduct has been larger in CH group than in WHD group,
due to the generally wider aqueductal diameter in communicating hydrocephalus patients (Table 1),
and statistically significant difference between the groups has been found (p<0.05).
Bidirectional intraaqueductal CSF net flow has been significantly higher in CH group in comparison to WHD group (p<0.001); also the summary net flow values were significantly higher in CH than in WHD group (p<0.05),
whereas in CH group net CSF flow has been found to be of predominantly caudo-cranial direction (+0.053 ± 0.175ml/s),
and in WHD group predominantly of cranio-caudal direction (-0.018 ± 0.047ml/s) (Table 2).
The characteristic curves of CSF net flow through the single cardiac cycle are shown on figure 3.
Average CSF velocities were significantly higher in CH group in comparison to WHD group (p<0.05 in cranio-caudal direction and p<0.001 in caudo-cranial direction) (Table 3).
Specific curves of average CSF velocities through the single cardiac cycle are presented on figure 4.
Bidirectional maximal CSF velocities were significantly higher in CH group compared to WHD group (p<0.001) (Table 4),
and the maximal velocities values in both cranio-caudal and caudo-cranial directions through the single cardiac cycle are graphically presented by characteristically shaped curves (Fig.
5).
