title: Measurement of the blood flow velocity in the pericallosal artery of children with hydrocephalus by transcranial Doppler ultrasonography--preliminary results.
abstract: OBJECTIVE
  The goal of this study was to evaluate selected parameters of the Doppler curve of the pericallosal artery at children with hydrocephalus.
  
  
  METHODS
  12 patients with hydrocephalus were divided into two groups. Group 1 comprised children needing cerebrospinal fluid drainage, and group 2 comprised children without any indication for drainage or with an already inserted well-functioning drainage system. Dilatation of the cerebral ventricles was determined by transcranial ultrasonography. Following parameters of a blood flow of the pericallosal branch of the anterior cerebral artery: peak systolic blood flow velocity (PSFV), end-diastolic blood flow velocity (EDFV) and resistive index (RI) were observed by transcranial Doppler ultrasonography. Parameters of The Doppler curve were measured without pressure (baseline parameters) and during compression of the anterior fontanelle (pressure provocation test).
  
  
  RESULTS
  Group 1: baseline parameters: PSFV 68.9 +/- 13.52 cm/s, EDFV 18.26 +/- 10.39 cm/s, RI 0.76 +/- 0.12; parameters during pressure provocation test: PSFV 66.92 +/- 19.75 cm/s, EDFV 10.88 +/- 11.18 cm/s, RI 0.86 +/- 0.14. Group 2: baseline parameters: PSFV 59.95 +/- 19.38 cm/s, EDFV 20.65 +/- 8 cm/s, RI 0.65 +/- 0.04; parameters during the pressure provocation test: PSFV 57.14 +/- 18.91 cm/s, EDFV 17.7 +/- 8.3 cm/s, RI 0.68 +/- 0.05.
  
  
  CONCLUSIONS
  The results show increased baseline and postcompressive values of RI of pericallosal artery in infants with hydrocephalus before drainage procedure and normal values of RI at children without the need for cerebrospinal fluid drainage or with a well-functioning drainage system.
