METHODS: This study has a retrospective design. Thirty-two patients who had failed routine removal of the port catheter and were then transferred to interventional radiology between November 2017 and December 2023 were reviewed. The technical success and complication rates were recorded.
RESULTS: All adherent catheters were successfully removed without catheter fragmentation, using guidewire support (n = 21), antegrade coaxial separation (n = 5), and retrograde coaxial separation (n = 6). The technical success rate was 100%, and no complications occurred.
CONCLUSIONS: The proposed stepwise interventional strategy successfully removed adherent port catheters, with good safety and high effectiveness. It appeared to reduce the incidence of catheter fracture during the removal of adherent totally implantable central venous access port catheters.
方法:本研究采用回顾性设计。回顾了在2017年11月至2023年12月之间常规拔除端口导管失败然后转移到介入放射科的32例患者。记录技术成功率和并发症发生率。
结果:所有粘附导管均成功移除,导管未破裂,使用导丝支撑(n=21),顺行同轴分离(n=5),和逆行同轴分离(n=6)。技术成功率100%,无并发症发生。
结论:建议的逐步介入策略成功地移除了粘附端口导管,具有良好的安全性和高效性。在移除粘附的完全可植入的中心静脉接入端口导管期间,它似乎减少了导管骨折的发生率。
