RESUMEN
Objective To analyze the reasons of catheter fracture of implantable vascular access devices and to explore the prevention and handling measures. Methods A retrospective analysis was carried in 3 887 adult patients with implantable vascular access devices and 13 had catheter fracture. The clinical features and causes were analyzed and the successful handling measures were summarized. Results Of 3 887 cases, a total of 13 (0.33%) catheter fracture occurred. The incidence rate of catheter fracture via subclavian jugular venipuncture was 3.70%,(6/162) , via internal jugular venipuncture was 0.18% (7/3 725), via internal jugular venipuncture was significantly lower than that via the subclavian venipuncture (χ2=47.505,P=0.000). There had no statistical differences between the left and right of the two puncture ways(P=0.707,0.682). Conclusions Catheter fracture is one of the serious complications in the process of use and maintenance of implantable vascular access device. Choosing appropriate surgical method, strengthen maintenance education, specificating the operation procedure, closing observation and other measures can not only reduce the occurrence of the catheter fracture, but also can dealt with catheter fracture in time, which could ensure the safety of patients' life.
