BACKGROUND
Several complex pediatric neurovascular conditions are amenable to endovascular treatment. Given the unique anatomical and physiological challenges in children, there is an ongoing need for tools and techniques that provide accurate information for treatment planning, while minimizing exposure to ionizing radiation and contrast. This is more so for neonates and infants with high-flow arteriovenous (AV) shunts that are challenging to assess using conventional techniques.
OBJECTIVE
In this brief report, we describe, through representative cases, the potential role of quantitative color-coded digital subtraction angiography (qDSA) in neuroendovascular procedures in children with high-flow AV shunting lesions.
METHODS
Images were obtained using an ArtisQ biplane system (Siemens Healthineers, Erlangen, Germany). Post-processing was performed at a dedicated workstation (Syngo, Siemens) using the iFlow module to generate color-coded maps of individual digital subtraction angiography runs.
CONCLUSION
Color-coded qDSA provides real-time quantitative information in high-flow AV shunting neurovascular lesions. This can potentially help direct treatment choices, optimize endovascular treatment protocols, monitor outcomes, and determine treatment end points.
背景
几种复杂的儿科神经血管疾病适合进行血管内治疗。鉴于儿童独特的解剖和生理挑战，持续需要能够为治疗规划提供准确信息，同时尽量减少电离辐射和造影剂暴露的工具和技术。对于使用传统技术难以评估的高流量动静脉（AV）分流的新生儿和婴儿来说更是如此。
目的
在本简要报告中，我们通过代表性病例描述定量彩色编码数字减影血管造影（qDSA）在患有高流量AV分流病变的儿童神经血管介入手术中的潜在作用。
方法
使用ArtisQ双平面系统（德国埃尔兰根西门子医疗公司）获取图像。在专用工作站（西门子Syngo）使用iFlow模块进行后处理，以生成各个数字减影血管造影序列的彩色编码图。
结论
彩色编码qDSA可为高流量AV分流神经血管病变提供实时定量信息。这可能有助于指导治疗选择、优化血管内治疗方案、监测结果并确定治疗终点。
