对１７例正常儿童与２２例脑性瘫痪患儿的３５１条颅内动脉行双功能彩色多普勒（ＴＣＤ）检测。结果显示，正常组和脑瘫组组内个体颅内各动脉血流参数无显著性差异（Ｐ＞０．０５）；两组间大脑前动脉（ＡＣＡ）、大脑中动脉（ＭＣＡ）、大脑后动脉（ＰＣＡ）的平均血流速度（Ｖｍ）和舒张期末血流速度（Ｖｅｄ）有显著性差异（Ｐ＜０．０５）。脑瘫组颅内动脉血流速度均低于正常组，且搏动指数（ＰＩ）、脑血管阻力指数（ＲＩ）及收缩峰与舒张期末血流速度比（Ｓ／Ｄ）值普遍高于正常组，其中基底动脉（ＢＡ）的ＰＩ及Ｓ／Ｄ值两组间差异性显著（Ｐ＜０．０５）。与临床头颅ＣＴ比较表明，不论脑瘫患儿颅脑ＣＴ是否发现形态学改变，其颅内血流动力学变化均为高阻低速型。因此，在综合康复治疗中，改善和增加颅内血液供应是至关重要的。ＴＣＤ检测为脑瘫的治疗与评价提供了血流动力学依据。
Bifunctional color Doppler (TCD) was performed on 351 intracranial arteries in 17 normal children and 22 children with cerebral palsy. The results showed that there was no significant difference in intracranial arterial blood flow parameters between the normal group and the cerebral palsy group (P> 0.05). The ACA, MCA, (P <0.05). There was significant difference between PCA and Ved in the mean diastolic blood flow velocity (Vm) and diastolic blood flow velocity (Ved). Cerebral palsy group intracranial arterial blood flow velocity was lower than the normal group, and pulsatility index (PI), cerebrovascular resistance index (RI) and systolic peak and end diastolic blood flow velocity ratio (S / D) values were generally higher than the normal group, The PI and S / D values of basilar artery (BA) were significantly different between the two groups (P <0.05). Compared with the clinical head CT, regardless of cerebral palsy children with brain morphology found morphological changes, intracranial hemodynamic changes were high-impedance low-speed type. Therefore, it is of crucial importance to improve and increase intracranial blood supply in general rehabilitation. TCD detection provides a hemodynamic basis for the treatment and evaluation of cerebral palsy.
