A central venous catheter is the most common access for initiating hemodialysis. Prolonged access through a central venous catheter increases the risk of infection and dysfunction of the catheter with potential development of catheter-induced thrombosis and embolism. However, fracture and dislodgement of the catheter with subsequent embolization is an unexpected complication. Endovascular treatment is a promising method to remove intravascular foreign bodies. We herein report a case of a 58-year-old woman undergoing prolonged hemodialysis who required central venous catheter removal because of mechanical fracture of the tunneled cuffed catheter and its migration in the internal jugular vein. An urgent chest X-ray showed that the two free ends of the fractured tunneled cuffed catheter were located in the right atrium and right internal jugular vein. Phlebotomy of the internal jugular vein was successfully performed to retrieve the fractured tunneled cuffed catheter and the associated thrombi. In this case, phlebotomy for retrieval of the embolized catheter fragment extending into the right atrium was a safe alternative to an endovascular technique of catheter fragment retrieval. Phlebotomy preserved the integrity of the catheter fragment and its associated thrombus and was both cost-effective and safe.
中心静脉导管是开始血液透析的最常用途径。通过中心静脉导管进行长时间的通路会增加感染和导管功能障碍的风险,从而导致导管相关性血栓形成和栓塞。然而,导管的断裂和移位以及随后的栓塞是一种意外的并发症。血管内治疗是一种有前途的去除血管内异物的方法。本文报告了 1 例 58 岁女性患者,因隧道带袖套中心静脉导管机械性断裂及其在内颈静脉内迁移而需要中心静脉导管取出。紧急胸部 X 线片显示断裂的隧道带袖套中心静脉导管的两个游离端位于右心房和右颈内静脉。成功地进行了颈内静脉采血以取回断裂的隧道带袖套中心静脉导管和相关血栓。在这种情况下,对延伸至右心房的栓塞导管碎片进行采血取回是一种替代血管内导管碎片取回技术的安全方法。采血保留了导管碎片及其相关血栓的完整性,既具有成本效益又安全。
