【摘要】 目的:研究儿童脑瘫患儿行颈总动脉交感神经网剥脱术后脑血流是否增加,症状是否改善,脑血流改变是否有长期效果。方法:对各种类型脑瘫患儿均行手术前后设定时间的脑血流变化进行检测,比较脑血流变化及与时间的变化有无关系,并对症状的变化进行分析。结果:手术后颈总动脉及颈内动脉血流平均速度和阻抗指数改变较术前有显著意义,颅内动脉(ACA、MCA、PCA)的平均血流速度增加及阻抗指数降低与术前比较有显著意义,术后1年与术后3个月比较无差异;术后症状大为改善。结论:脑瘫患儿颈总动脉交感神经网剥脱术能增加颅内脑血流并且是持续的,对手足徐动型和混合型脑瘫患儿效果更好。更多还原

【Abstract】 Objectives :To investigate if cerebral hemorrheology can be raised,symptom was improved and if cerebral hemorrheology change can endure long time for sympathetic plexus stripping of common carotid Arteria in treating cerebral palsy.Methods:Cerebral hemorrheology changes were detected in different type of cerebral palsy cases at setting time before and after operation,and explored if cerebral hemorrheology changed with the time,and analysed the improvement of symptom.Results:In common carotid arteria,arteria carotis interna and intracranial arteria,mean blood speed raised significantly,and impedance index depressed after operation compared to pre-operation,and it had no significant differences between three month and one year after operation,Symptoms improved obviously after stripping.Conclusion:The sympathetic plexus stripping of pericommon carotid Arteria in treating cerebral palsy could improve the cerebral blood volume continuously,especially to athetosis and mixed type.更多还原
