To evaluate the feasibility and safety of a method to withdraw port-catheter systems implanted by the fixed catheter tip method.
Retrospective review was conducted of 14 cases of unresectable advanced liver cancer in which it was necessary to attempt 15 withdrawals of percutaneously placed implantable port-catheter systems. Reasons for withdrawal, withdrawal success, complications, and subsequent treatment of patient were evaluated.
In 14 of the 15 procedures (93.3%), the port-catheter system was successfully retrieved. Because continuation of hepatic arterial infusion chemotherapy was necessary in 10 procedures, a second implantation was performed after withdrawal of the initial catheter. Only one complication occurred, in which the indwelling catheter was broken in the aorta during withdrawal.
When retrieval of a port-catheter system implanted with the fixed catheter tip method is necessary, withdrawal can be accomplished safely with high frequency.
评估一种通过固定导管尖端法植入的端口导管系统取出方法的可行性和安全性。
对14例无法切除的晚期肝癌患者进行回顾性研究，这些患者中有15次经皮植入可植入端口导管系统的取出尝试。评估取出原因、取出成功率、并发症以及患者的后续治疗情况。
15次操作中有14次（93.3%）成功取出端口导管系统。由于10次操作中需要继续进行肝动脉灌注化疗，在取出初始导管后进行了第二次植入。仅发生1例并发症，即取出过程中留置导管在主动脉内断裂。
当需要取出通过固定导管尖端法植入的端口导管系统时，取出操作可以高频率安全完成。
