Background: We evaluated the improvement in the gray and white matter functional areas in children with cerebral palsy (CP) after common carotid artery sympathetic neural network ablation. We also analyzed the relationship between the values of the diffusion kurtosis imaging (DKI) parameters and clinical signs in children with CP.
Methods: We collected data from 22 children with unilateral spastic CP who had undergone common carotid sympathetic neural network ablation in our hospital from January 1, 2014 to December 1, 2018, using magnetic resonance kurtosis imaging technology parameters.
Results: The study found that the changes from preoperatively to postoperatively in the kurtosis fractional anisotropy (KFA) values for the frontal lobe, parietal lobe, temporal lobe, internal sac forelimb, and corpus callosum were statistically significant. However, the changes in the internal sac forelimb, corpus callosum, and KFA values were not statistically significant. The changes from preoperatively to postoperatively in the mean kurtosis (MK) values for the frontal lobe, parietal lobe, temporal lobe, hindlimb of the internal capsule, corpus callosum, and caudate nucleus were statistically significant. However, the MK values for the forelimb, corpus callosum, and thalamus were not statistically significant. The 66-item gross motor function measure scores correlated negatively with the KFA value and positively with the MK value.
Conclusion: Therefore, it can be concluded that DKI technology can more accurately reflect the gray and white matter damage in children with CP, and the DKI parameters can be used as a monitoring and evaluation index for children with CP.
