Implanted venous ports in children are commonly placed by pediatric interventional radiologists, primarily through the internal jugular vein to allow long-term delivery of intravenous access. The ideal location of the catheter tip is the junction of the superior vena cava and right atrium. High catheter tip positions may result in failure of the port catheter due to venous thrombosis, catheter occlusion, or fibrin sheath formation, whereas low catheter tip positions may cause catheter occlusion, cardiac arrhythmias, or perforation. This chapter describes indications, contraindications, equipment, techniques, and complications of the endovascular snaring technique of central venous port tip revision in children.
