TREATMENT OPTIONS
Thermal Ablation
Thermal ablative procedures may use heat, laser or radiofrequency energy to close the diseased vein, which redirects blood flow to healthy veins. Thermal ablative treatments are minimally invasive procedures performed by your doctor using thermal energy.
Radiofrequency ablation (RFA)
Radiofrequency ablation is delivered through a small catheter to shrink and cut off blood to the diseased vein.
This is typically a 30- to 60-minute outpatient (same-day) procedure performed on one leg per appointment, with local anaesthesia along the leg.
Step-by-step RFA procedure
STEP 01
Before therapy
You will have an ultrasound imaging exam of the leg being treated. This exam is important for assessing the diseased superficial vein and planning the procedure.
Step-by-step procedure
STEP 02
During therapy
- Using an ultrasound, your doctor will position a catheter in the diseased vein through a small opening in the skin.
- The small catheter delivers heat to the vein wall, causing it to shrink and seal the vein. Once the diseased vein is closed, blood will reroute itself to other healthy veins.

STEP 03
After therapy
- Following the procedure, your doctor will apply a simple bandage over the insertion site and will give you compression stockings to aid in the healing process. Your doctor may encourage you to walk and to refrain from extended standing and strenuous activities for a period of time. The average patient typically resumes normal activities within a few days.1,2
