What is this test?
This is a procedure rather than a blood test. A central venous catheter, or CVC, is replaced under imaging guidance, and intravenous contrast may be given to help show the veins and confirm the catheter's position.
Why might I need this test?
A CVC may need to be replaced if it is damaged, leaking, blocked, infected, or no longer positioned correctly. It may also be exchanged according to a routine schedule or when a specific type of catheter is required.
How is the test performed?
After numbing the insertion area, a clinician uses imaging to guide placement of the new catheter through a central vein. Intravenous contrast is administered through a vein, and the catheter is checked before the procedure is completed.
How do I prepare for the test?
Tell the healthcare team about any contrast allergy, kidney disease, pregnancy, bleeding problems, or medicines that increase bleeding risk. Follow the facility's instructions about fasting, medications, and arrival, particularly if sedation or local anesthesia will be used.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
There are no diagnostic analyte values or reference ranges for this procedure. Imaging findings may reveal catheter malposition, blockage, vein injury, leakage, or an abnormal collection of fluid. The clinical team will interpret these findings together with symptoms and the reason the catheter was being replaced.
Short name
Image-guided CVC replacement with IV contrast
