Faulty vein
Weak valves let blood flow backward and pool in the leg.
VenaSeal
Close the faulty vein—without heat.
If aching, heaviness, swelling, or visible varicose veins are linked to venous reflux, VenaSeal uses medical adhesive to close the problem vein. Blood then moves through healthier veins.
Your visit starts with an exam and duplex ultrasound. VenaSeal is recommended only when the vein findings match your symptoms and the adhesive is appropriate for you.
How VenaSeal redirects blood flow
A small amount of medical adhesive closes the refluxing vein from the inside.
Adhesive placed

Vein closed

Symptoms That May Point to Venous Reflux
These symptoms can build through the day or after long periods of standing. A duplex ultrasound can show whether a faulty vein is contributing to the problem.
Aching or heavy legs
Leg or ankle swelling
Bulging varicose veins
Itching or burning
Skin color or texture changes
Nighttime restlessness or cramping
How VenaSeal Closes a Faulty Vein
A refluxing superficial vein lets blood fall backward and pool in the leg. VenaSeal closes that vein from the inside, so your body naturally redirects blood through veins that are working properly.
- The problem vein is mapped with duplex ultrasound.
- A thin catheter enters through a small, numbed access point.
- Small amounts of medical adhesive close the vein in sections.
- The catheter is removed and a small bandage covers the entry site.
The adhesive remains in the closed vein.
VenaSeal is a permanent implant. Your specialist will review your medical and allergy history before recommending it.
How the VenaSeal Procedure Works
The procedure is planned from your ultrasound and performed through one small vein-access point.
Map the problem vein
Duplex ultrasound confirms where blood is flowing backward and guides the treatment path.
Place a thin catheter
The access area is numbed, and a small catheter is guided into the faulty vein.
Seal the vein
Small amounts of adhesive are delivered as gentle pressure helps close the vein in sections.
Redirect blood flow
The catheter is removed, and blood moves through healthier veins in the leg.
VenaSeal vs. Heat-Based Ablation
Both treatments close a faulty vein. The difference is how they do it—and the right choice depends on your anatomy, history, symptoms, and coverage.

How the vein closes
Medical adhesive
Adhesive closes the vein without heat.
Controlled heat
Radiofrequency or laser energy closes the vein.
Numbing
At the access point
The small entry area is numbed.
Along the treated vein
Numbing fluid is placed around the vein.
What remains
Medical adhesive
The adhesive remains in the closed vein.
No thermal device
The catheter is removed after treatment.
Aftercare
Compression may not be routine
Follow your specialist’s instructions.
Compression may be recommended
Aftercare depends on the treatment plan.
Your specialist will explain which option best fits your ultrasound, medical history, and treatment goals.
What May Improve After Treatment
VenaSeal treats the refluxing source vein. Symptom and appearance changes vary, and some surface veins may need separate treatment.
Less aching and heaviness
Treating the source of venous pressure may make standing and daily activity more comfortable.
Less end-of-day swelling
Some patients notice less tightness, fatigue, or swelling as the leg adjusts.
A clearer next step for visible veins
Remaining varicose or spider veins can be reassessed after the source vein is treated.
Individual results vary. Your specialist will explain what improvement is realistic for your symptoms and vein pattern.
Is VenaSeal Right for You?
A visible vein alone does not decide treatment. The right plan connects your symptoms with your exam, ultrasound, medical history, and treatment goals.
- Duplex ultrasound confirms reflux in a superficial truncal vein.
- Aching, heaviness, swelling, skin changes, or varicose veins affect daily comfort.
- Your vein anatomy is suitable for adhesive closure.
- You do not have a known allergy to the VenaSeal adhesive or cyanoacrylates.
What Recovery Often Looks Like
Recovery is usually straightforward, but your instructions depend on the vein treated, other procedures completed, and your health.
Treatment day
Walk before you leaveMany patients walk soon after treatment. A small bandage covers the vein-access site.
First few days
Follow your activity planYour specialist will explain walking, exercise, bathing, travel, and whether compression is recommended.
What you may feel
Mild tenderness can occurBruising, soreness, inflammation, or a pulling sensation can occur along the treated vein.
Follow-up
Review healing and symptomsYour plan may include an office visit or ultrasound and a discussion of remaining surface veins.

Your VenaSeal Questions, Answered
Clear answers about treatment, recovery, safety, and insurance.
What is VenaSeal?
VenaSeal is an ultrasound-guided treatment that uses medical adhesive to permanently close a faulty superficial vein. Blood then moves through healthier veins.
How is VenaSeal different from radiofrequency or laser ablation?
VenaSeal uses medical adhesive instead of heat, so it does not require tumescent anesthesia along the vein. The right option depends on your ultrasound, anatomy, history, and treatment goals.
Does the medical adhesive stay in my body?
Yes. The adhesive is a permanent implant. It remains in the closed vein and becomes surrounded by the body’s healing response.
Do I need compression stockings after VenaSeal?
Compression stockings may not be routinely required after VenaSeal, but aftercare varies. Follow the individualized instructions from your specialist.
Who should not receive VenaSeal?
VenaSeal is not appropriate for everyone. It should not be used with a known hypersensitivity to the adhesive or cyanoacrylates, acute superficial thrombophlebitis, thrombophlebitis migrans, or acute sepsis. Your specialist will review your history.
What is recovery like?
Many patients walk soon after treatment and return to normal activity quickly. Activity, travel, compression, and follow-up instructions are individualized.
Will VenaSeal remove every visible vein?
VenaSeal treats the faulty source vein. Some visible veins may improve, while remaining varicose or spider veins may need a separate treatment such as sclerotherapy or phlebectomy.
Does insurance cover VenaSeal?
Coverage depends on the plan, network, symptoms, ultrasound findings, medical-necessity rules, and authorization requirements. EVSLA can review your plan details before scheduling.
