Long-term central venous catheters are placed for total parenteral nutrition and/or chemotherapy. These catheters are placed surgically and fixed to the subcutaneous tissues. Complications include infection, venous thrombosis, and mechanical problems. The authors developed a method to percutaneously reposition displaced central venous catheters. The procedure is performed with fluoroscopy and modified angiographic techniques. Fifteen patients underwent a total of 17 procedures. The initial success rate was 76%; the final success rate was 88%. Many central venous catheters can be salvaged with this low-morbidity procedure, which negates the need for surgical intervention.
长期中心静脉导管用于全胃肠外营养和/或化疗。这些导管通过手术放置并固定于皮下组织。并发症包括感染、静脉血栓形成和机械问题。作者开发了一种经皮重新定位移位中心静脉导管的方法。该操作通过荧光透视和改良血管造影技术进行。15例患者共接受了17次操作。初始成功率为76%；最终成功率为88%。许多中心静脉导管可通过这种低发病率的操作挽救，从而无需手术干预。
