Making use of transcranial Doppler sonographic (TCD) technology to monitor the preoperative and postoperative changes in cerebral hemodynamics of sick children with craniostenosis and to evaluate the effects brought about by decompression surgery of craniostenosis by means of various changes in the parameters of cerebral blood flow. ⋯ Operation can improve obviously younger sick children's cerebral blood flow velocity and PI; for older children, the improvement of diastolic cerebral blood flow velocity was more obvious than that of systolic cerebral blood flow velocity, and PI reduced distinctly, which showed that decompression surgery had a perfect effect on craniostenosis. The TCD parameters of an 11-year-old sick child who has a smaller head circumference but without intracranial hypertension could not be improved obviously. Transcranial Doppler sonography can be regarded as a simple and convenient tool for the noninvasive evaluation on the effect of decompression surgery of craniostenosis.
