Experience with intravenous digital subtraction angiography (DSA) in infants and children is limited, although its relative ease of performance, low complication rate, and diagnostic accuracy indicate great potential. We performed 87 DSA examinations (74 patients) and obtained sufficient detail to facilitate diagnosis in most cases. The major problems of patient movement and overlapping vessels can be minimized by judicious use of sedation and strict attention to technique. Exposure of patients to radiation has not been a limiting factor since our system uses low exposure factors (2-38 mR [.51-9.76 mu C/kg]/frame). Our results demonstrate that DSA has wide applicability to many organ systems and is especially useful in intracranial disease and for preoperative evaluation of neoplasms. More specific indications for its use in children must await further correlative studies.
尽管静脉数字减影血管造影（DSA）相对易于操作、并发症发生率低且诊断准确性高，显示出巨大潜力，但婴幼儿患者的静脉DSA检查经验有限。我们进行了87例DSA检查（涉及74例患者），并在大多数情况下获得了足以助于诊断的详细信息。通过合理使用镇静剂和严格注意技术，可将患者移动和血管重叠等主要问题降至最低。由于我们的系统使用低曝光因子（每帧2 - 38毫伦琴[0.51 - 9.76微库仑/千克]），患者所受辐射暴露并非限制因素。我们的结果表明，DSA在许多器官系统中具有广泛适用性，尤其在颅内疾病和肿瘤术前评估中很有用。其在儿童中使用的更具体指征有待进一步的相关性研究。
