Abstract：
A vessel port, implanted into the central venous system, is used for long-term intravenous drug administration in oncology patients. Although essential for frequent chemotherapy and other treatments, ports can lead to complications such as infection and thrombosis. This article discusses a rare but serious complication: the displacement of a catheter fragment. A 67-year-old gastric cancer patient, experienced malignant recurrence with jaundice and bile duct infiltration post Roux-Y subtotal gastrectomy and D2 lymphadenectomy. After nine cycles of chemotherapy, a catheter fragment from the venous port detached and lodged in a branch of the pulmonary artery in segment VIII of the right lung. Thoracotomy was performed to remove the foreign body. Our aim is to report on the surgical treatment of a displaced detached catheter and to raise awareness about the potential rare complications associated with the use of vascular ports in patients undergoing chronic oncological treatment. Additionally, we screened the PubMed database for similar surgical treatment reports and compared the collected data. Venous port malfunction or non-specific patient symptoms may indicate rare complications, such as port component detachment, necessitating a multidisciplinary approach for prompt diagnosis and management in oncological patients.
摘要：
一个船只港口，植入中心静脉系统,用于肿瘤患者的长期静脉给药。尽管对于频繁的化疗和其他治疗至关重要，港口可导致感染和血栓形成等并发症。本文讨论了一种罕见但严重的并发症：导管碎片的移位。一位67岁的胃癌患者,Roux-Y胃大部切除术和D2淋巴结清扫术后出现恶性复发伴黄疸和胆管浸润.经过九个周期的化疗,静脉端口的导管碎片脱离并滞留在右肺VIII段的肺动脉分支中。进行了开胸手术以去除异物。我们的目的是报告移位的分离导管的手术治疗，并提高人们对接受慢性肿瘤治疗的患者使用血管端口相关的潜在罕见并发症的认识。此外,我们在PubMed数据库中筛选了相似的手术治疗报告,并比较了收集的数据.静脉端口故障或非特异性患者症状可能表明罕见的并发症。如端口组件拆卸，需要多学科方法来迅速诊断和管理肿瘤患者。
