摘　　要：目的探讨经皮左锁骨下动脉穿刺导管药盒系统置入术后留置管移位的原因及处理方法。方法观察行经皮左锁骨下动脉穿刺导管药盒系统置入术晚期癌症患者３４８例。随访２个月～３年。对留置管脱出移位者，予以经原途径更换新的留置导管或拔除导管药盒系统。结果留置导管移位２５例。其中１８例更换新的留置管均成功，３例将导管药盒系统拔除。结论经皮左锁骨下动脉穿刺导管药盒系统置入术后留置管移位的原因有：（１）靶血管与腹主动脉间的头向夹角偏小；（２）留置管在靶动脉内长度偏小；（３）靶血管狭窄，血流量减少。留置导管移位后，可经原途径更换新的留置导管或将导管药盒系统拔除。Objective To study the causes and management of dislocation of indwelling catheter after port catheter system(PCS) implantation via subclavian artery(SCA). Materials and Methods PCS implantation via SCA was successfully performed in 348 patients with advanced cancers. The follow up period was 2～36 months. A new indwelling catheter was inserted into the target artery via the same route or PCS was pulled out when the dislocation of indwelling catheter was detected. Results Dislocation of indwelling catheter was observed in 25 cases. A new indwelling catheter was successfully replaced in 18 cases. PCSs were pulled out in 3 patients. Conclusion Dislocation of indwelling catheter could be related to: (1) The headward angle of target artery and abdominal aorta was smaller.(2) The indwelling catheter in the target vessel was shorter. (3) The target artery was narrowed causing the decrease of blood flow in the target artery. When indwelling catheter migrated, a new indwelling catheter should be reinserted into the target artery via the same route or PCS could be removed.
