报道1例带隧道和涤纶套的透析导管(tunnel-cuffed catheter，TCC)路厄氏接头完整性受损，经更换路厄氏接头成功修复导管功能的案例，为临床医护人员处理血液透析导管外部部件相关并发症提供新思路。
This article reports a case of a tunnel-cuffed catheter for hemodialysis with compromised integrity of the Luer interface, which was successfully repaired by replacing the Luer interface to restore function of the catheter. This case provides a new approach for clinical medical staff to deal with complications related to the extracorporeal extension segment of hemodialysis catheters.
