We describe a case of inadvertent intrathecal cannulation with a central venous catheter in an infant, confirmed by three-dimensional computed tomography, which clearly demonstrated the track of the catheter. We believe that this complication could have been related to two major factors: depth of needle insertion and penetration of the vein by a straight-tip guidewire. To avoid this complication, the depth of needle insertion must be carefully checked, a "J"-tipped rather than a straight-tipped guidewire should be used, and puncture should be guided by ultrasound.
我们描述了一例婴儿使用中心静脉导管意外鞘内插管的病例，经三维计算机断层扫描证实，该扫描清晰显示了导管的路径。我们认为，这一并发症可能与两个主要因素有关：进针深度和直头导丝穿透静脉。为避免这一并发症，必须仔细检查进针深度，应使用“J”形头而非直头导丝，并应在超声引导下进行穿刺。
