Three cases of histologically proven nerve root avulsion during Pantopaque removal with a Cuatico needle are described. While use of such multihole needles poses some risk to patients, we feel the advantages outweigh the disadvantages, particularly when a large volume of Pantopaque has to be removed. To minimize the possibility of nerve root avulsion, we recommend minimal manipulation of the needle and cannula during Pantopaque removal, use of gentle suction, termination of suction and injection of cerebrospinal fluid if pain occurs, and slow withdrawal of the cannula and stylet.
本文描述了3例在使用Cuatico针清除碘苯酯过程中经组织学证实的神经根撕脱病例。虽然使用这种多孔针会给患者带来一些风险，但我们认为其优点大于缺点，尤其是在必须清除大量碘苯酯的情况下。为了将神经根撕脱的可能性降至最低，我们建议在清除碘苯酯时尽量减少对针和套管的操作，采用轻柔的吸引，若出现疼痛则停止吸引并注入脑脊液，以及缓慢拔出套管和探针。
