Totally implanted port devices are important for the administration of fluid and chemotherapeutic agents. However, their use may be associated with serious complications, such as catheter fracture and embolism. Most data on port catheter embolization consist of isolated case reports. We report a 6-year-old boy with relapse of an acute lymphoblastic leukemia. He presented with dysfunction of his totally implanted port device. Radiologic examination revealed a catheter fracture. Echocardiography showed the catheter embolized into the right ventricle. The catheter was successfully removed from the right ventricle by percutaneous endovascular intervention. During the procedure, it was observed that the catheter fragment was located in the pulmonary artery. Catheter embolism may go undiagnosed for a prolonged period; however, severe systemic clinical signs may develop. Any implanted catheter should be removed after completion of treatment, or should be checked regularly for this complication by periodic standard chest x-ray monitoring.
全植入式端口装置对于液体和化疗药物的给药很重要。然而，其使用可能与严重并发症相关，如导管断裂和栓塞。关于端口导管栓塞的大多数数据均为孤立的病例报告。我们报告一名6岁急性淋巴细胞白血病复发男孩。他出现全植入式端口装置功能障碍。放射学检查显示导管断裂。超声心动图显示导管栓塞入右心室。通过经皮血管内介入成功从右心室取出导管。在此过程中，观察到导管碎片位于肺动脉。导管栓塞可能长时间未被诊断；然而，可能会出现严重的全身临床症状。任何植入的导管在治疗完成后都应取出，或应通过定期标准胸部X线监测定期检查是否有此并发症。
