Frontal chest radiographs can be misleading in the evaluation of central venous catheter placement. Lateral chest radiographs were obtained, in addition to the standard frontal radiographs, in 25 young children. In five (20%) of the children, the catheters were found to be malpositioned, and the frontal radiograph showed evidence of the abnormality in all five. The lateral radiographs also showed evidence of the abnormality in all five children; however, in three of the five, the lateral radiographs provided additional, more specific, diagnostic information. The lateral chest radiographs also demonstrated satisfactory catheter positioning in three other children in whom the frontal radiographs suggested abnormal positioning. Accurate assessment of catheter position was possible in all patients using both frontal and lateral chest radiographs. Injection of contrast material was not necessary to locate malpositioned catheters. Lateral radiographs are recommended whenever an abnormal catheter position is suspected clinically or from findings on the routine frontal radiograph.
在评估中心静脉导管置入情况时，胸部正位X线片可能会产生误导。除了标准的胸部正位片外，还对25名幼儿进行了胸部侧位X线片检查。在5名（20%）儿童中，发现导管位置不当，且所有5名儿童的胸部正位片均显示有异常迹象。所有5名儿童的胸部侧位片也显示有异常迹象；然而，在这5名儿童中的3名中，胸部侧位片提供了更多、更具体的诊断信息。胸部侧位片还显示，另外3名胸部正位片提示导管位置异常的儿童，其导管位置正常。使用胸部正位片和侧位片可以对所有患者的导管位置进行准确评估。对于位置不当的导管，无需注射造影剂来定位。只要临床上怀疑导管位置异常或根据常规胸部正位片的检查结果怀疑导管位置异常，就建议拍摄胸部侧位片。
