What is this test?
This is an imaging-guided procedure rather than a blood test. A port venous catheter is placed through a vein, using a right femoral approach, and intravenous contrast may be given to help check the catheter's position.
Why might I need this test?
A central venous port may be recommended when repeated IV access is needed for treatments such as chemotherapy, antibiotics, or nutritional support. It can also be used for reliable blood sampling when other access routes are unsuitable.
How is the test performed?
After numbing the access site, the clinician uses imaging guidance to insert the catheter into a central vein and position the port beneath the skin. Contrast may be administered through the catheter, and the final position is checked before the procedure is completed.
How do I prepare for the test?
Follow the facility's instructions about medications, allergies, and fasting. Tell the care team if you have kidney disease, a contrast allergy, bleeding problems, or take blood thinners, because these factors may affect the procedure or contrast use.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Successful placement allows long-term access to a central vein. The imaging and contrast help identify problems such as catheter malposition or blockage, while monitoring also reduces the risk of major complications. Later signs of trouble may include redness, drainage, pain, swelling, or fever at the port site.
