Totally implantable venous ports are the main access for chemotherapy. The complications associated with these devices occur most frequently over the course of their use. We report two cases of a complication that had only been described in patients with partially implantable catheters for hemodialysis: retention of a catheter fragment within a vessel during port removal. Both patients underwent adjuvant chemotherapy through the port and even after indication of catheter removal because at the end of treatment, they remained with the devices for long periods of time (7 and 8 yrs, respectively). Due to adherence of the catheters along their intravascular portions, complete removal was impossible. The catheters were sectioned and ligated close to the site where it entered the access vein. After 1 yr of follow-up, both patients were asymptomatic and imaging examinations showed the retained catheters. We believe that an implantable port should be removed after appropriate oncological follow-up.
完全植入式静脉端口是化疗的主要通路。与这些装置相关的并发症在其使用过程中最为常见。我们报告了两例仅在用于血液透析的部分植入式导管患者中描述过的并发症：在移除端口期间导管碎片滞留在血管内。两名患者均通过端口接受辅助化疗，甚至在指示移除导管后，由于治疗结束时他们长时间保留了这些装置（分别为7年和8年）。由于导管沿血管内部分粘连，无法完全移除。在靠近导管进入通路静脉的部位将导管切断并结扎。经过1年的随访，两名患者均无症状，影像学检查显示导管残留。我们认为，在适当的肿瘤学随访后应移除植入式端口。
