This study was performed to examine the effectiveness of color Doppler imaging (CDI) in demonstrating the neonatal intracranial vessels and altered intracranial flow patterns and to determine the optimal approach in imaging and intracranial vasculature. The study was conducted in two parts. First, 14 neonates were examined with CDI by using a standard approach through the anterior fontanel. Whenever possible, views through the posterior fontanel and the temporal bone were obtained also. The anterior cerebral, M1 segment of the middle cerebral, distal internal carotid, and basilar arteries were demonstrated consistently. Portions of the vertebral distal middle cerebral, and posterior cerebral arteries were frequently visualized. In the second part of the study, we examined 10 neonates who had undergone extracorporeal membrane oxygenation. In this group of patients, CDI was able to demonstrate occlusion of the right internal carotid artery and the reversal of flow through the ipsilateral A1 segment. Increased flow on the contralateral side and in the basilar artery was observed in several patients. The anterior fontanel approach was shown to be the most useful in identifying most of the major intracranial arteries and veins with CDI. In addition, the body weights and gestational ages of the neonates were found to significantly influence the success rate in visualizing the intracranial vasculature.
本研究旨在探讨彩色多普勒成像（CDI）在显示新生儿颅内血管及颅内血流模式改变方面的有效性，并确定颅内血管成像的最佳方法。该研究分两部分进行。首先，对14例新生儿采用经前囟的标准方法进行CDI检查。只要有可能，也会获取经后囟和颞骨的图像。大脑前动脉、大脑中动脉M1段、颈内动脉远端和基底动脉均能持续显示。椎动脉远端、大脑中动脉和大脑后动脉的部分也经常可见。在研究的第二部分，我们检查了10例接受体外膜肺氧合治疗的新生儿。在这组患者中，CDI能够显示右侧颈内动脉闭塞以及同侧A1段血流逆转。在数例患者中观察到对侧及基底动脉血流增加。经前囟途径在通过CDI识别大多数主要颅内动静脉方面显示出最为有用。此外，发现新生儿的体重和胎龄对颅内血管成像的成功率有显著影响。
