Frequently Asked Questions

How is ClosureFast different from vein stripping?
The ClosureFast procedure is minimally invasive. The vein is closed using heat delivered by a catheter inserted through a small incision below the knee. Vein stripping is usually performed in an operating room under general anaesthesia, while the ClosureFast procedure is often performed in an outpatient setting, typically using local anaesthesia.
How long does the ClosureFast procedure take?
The ClosureFast procedure itself takes around 25–30 minutes.
After the ClosureFast procedure, how quickly can I return to normal activities?
Most patients quickly return to normal activities (on average, three days). For a few weeks following the treatment, we may recommend that you refrain from very strenuous activities — such as heavy lifting — or prolonged periods of standing.
How soon will my symptoms improve after the ClosureFast procedure?
Patients have noticed an improvement in symptoms within 1–2 weeks post‑procedure.
What happens to the treated vein left behind in the leg?
After treatment, the affected vein becomes fibrous tissue. Over time the vein will be absorbed into surrounding tissue and blood will reroute to other veins.
Is ClosureFast covered by insurance?
Many insurance companies pay for the ClosureFast procedure in part or in full. Prior to scheduling the procedure, we will consult with your insurance provider to verify coverage.
How is VenaSeal different from ClosureFast
The VenaSeal Closure System uses a medical adhesive to close the superficial vein. Because ClosureFast uses heat to close the vein, a large volume of numbing medicine is used, which is injected through many needle sticks. VenaSeal does not require numbing medication.
What happens to the VenaSeal Closure System adhesive?
Only a small amount of adhesive is used to close the vein. The body naturally absorbs the adhesive over time.
After the VenaSeal procedure, how quickly can I return to normal activities
Most patients return to normal activities immediately following the procedure
Is the VenaSeal procedure painful?
Most patients feel little‐to‐no pain during the procedure.
