What is this test?
This is an imaging-based assessment of a vein treated with radiofrequency ablation or radiofrequency venous closure. Intravenous contrast may be used to help show the vein and identify changes in its appearance.
Why might I need this test?
The test may be used during or after a radiofrequency vein procedure to guide treatment, confirm that the intended vein has been closed, or evaluate the treated area. It may also be used to assess persistent or recurrent vein problems.
How is the test performed?
The test is generally performed using ultrasound or another imaging device while contrast is given through an intravenous line. Images are taken to evaluate the treated vein and nearby blood vessels. The exact imaging method depends on the clinical situation and the equipment used.
How do I prepare for the test?
Follow the instructions provided by the imaging facility, especially any directions about IV contrast. Tell the care team about kidney disease, previous contrast reactions, pregnancy, allergies, and medications that may affect imaging or bleeding. Do not stop prescribed medicines unless instructed to do so.
Reference range
INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A
Inform your healthcare provider if you are taking blood thinners. No special preparation required.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
The images may show whether the treated vein is closed, narrowed, reopened, or otherwise changed. Abnormal findings can suggest incomplete treatment, persistent venous flow, recurrence, swelling, or another complication. Interpretation should be combined with symptoms, examination findings, and other imaging or laboratory tests.
Short name
