To determine the value of color Doppler ultrasound (US) in the preoperative assessment and evaluation of treatment results in children with intracranial vascular malformations (VMs), the authors performed 36 color Doppler US studies in nine children who underwent endovascular embolization. Color flow imaging with spectral waveform analysis of feeding arteries, nidus, draining veins, and uninvolved cranial vasculature was performed, and correlation was made with other imaging findings. In most VMs, color Doppler US enabled the authors to map the lesion completely. Hemodynamic changes after embolization included improvement in blood supply to uninvolved portions of the brain and increase in caliber and flow of feeding vessels that were not occluded during embolization. Serial volume flow measurements were performed with Doppler US in major extracranial arteries. Success of embolization was indicated by substantial decrease of total carotid artery flow. Color Doppler US is a noninvasive modality that adds important imaging and hemodynamic data to those provided by angiography.
为了确定彩色多普勒超声（US）在儿童颅内血管畸形（VMs）术前评估及治疗效果评价中的价值，作者对9例接受血管内栓塞治疗的儿童进行了36次彩色多普勒超声检查。对供血动脉、病灶、引流静脉及未受累的颅内血管进行了彩色血流成像及频谱波形分析，并与其他影像学检查结果进行了对比。在大多数VMs中，彩色多普勒超声使作者能够完整地描绘出病变。栓塞后的血流动力学变化包括未受累脑区血供改善，以及栓塞过程中未闭塞的供血血管管径增粗、血流增加。采用多普勒超声对主要颅外动脉进行连续的血流量测量。颈动脉总血流量显著下降表明栓塞成功。彩色多普勒超声是一种无创检查方法，可为血管造影提供的影像及血流动力学数据增添重要信息。
