What is VenaSeal®?
VenaSeal® uses a specially formulated injectable adhesive to treat diseased veins. The adhesive, via endovenous delivery, permanently seals the vein shut, restoring healthy circulation and blood flow. This unique treatment removes varicose veins close to the skin's surface permanently. VenaSeal® may also be used to close the main veins in the leg that cause varicose veins.
The VenaSeal® Procedure
Before the procedure, your doctor will use a needle to numb the site where your vein will be accessed. Once the area is numb, a small catheter will be inserted into the vein. Patients may experience some slight pressure as the catheter is being placed.
Once the catheter is correctly in place, the catheter will deliver small amounts of medical adhesive to specific areas of the vein. Within seconds, the adhesive acts quickly, bonding the vein walls together to seal the diseased vein. Ultrasound will be used throughout this procedure to help guide and place the catheter correctly. Once complete, the catheter is removed, and a bandage is placed over the site. The vein will begin to harden permanently for the following few hours after treatment, eventually being absorbed by the body. Once the diseased vein seals, blood flow redirects to nearby healthy veins.

VenaSeal® Benefits for Varicose Veins
- Non-surgical treatment
- Approved by the FDA
- Minimal impact on daily life and activities
- Just one needle stick with minimal pain
- Reduced recovery time
Treatment Outcomes Using VenaSeal® Treatment
VenaSeal® is highly effective, minimally invasive, and safe. In addition, studies have shown a nearly 99% closure rate at six months post-treatment. A single, small injection site significantly reduces patients' discomfort and speeds up the recovery time. Also, VenaSeal® can treat more than one vein in the same procedure and does not require the use of compression stockings post-procedure.
Risks of VenaSeal® Treatment
VenaSeal® is minimally invasive with low risks. However, all medical procedures carry some inherent risk. Below are possible risks associated with VenaSeal®.
- Allergic reaction to the VenaSeal® adhesive
- Arteriovenous fistula
- Deep Vein Thrombosis
- Edema in the treated leg
- Hematoma
- Hyperpigmentation
- Infection at the access site
- Mild inflammation of the cutaneous and subcutaneous tissue
- Phlebitis
- Pulmonary embolism
- Urticaria or ulceration at the injection site
- Vascular rupture and perforation
- Visible scarring
- Speak with your doctor to learn whether VenaSeal® is appropriate.
Other Vein Treatments
Sclerotherapy
Sclerotherapy involves the injection of a solution (“sclerosant”) or foam directly into the varicose vein. The solution irritates the vein, causing it to shrink and collapse.
Endovenous Laser Ablation
Laser ablation utilizes laser heat to contract and seal the unhealthy vein. The heat ultimately causes the vein to contract and seal shut. Unlike the ClosureFast, peak laser temperatures can reach over 1334 F (729 C), which can lead to more pain and bruising after treatment.
Vein Stripping
During vein stripping, your doctor will make an incision in your groin and tie off the diseased vein. A tool is then threaded through the leg vein to pull the vein out through a second incision made just above your calf.

Frequently Asked Questions
There are very few side effects associated with VenaSeal®. The most common side effect reported is vein inflammation, known as phlebitis or swelling of the vein.
Many patients return to their regular activity shortly after the procedure.
Unlike other heat-based treatments, VenaSeal® does not involve multiple injections of anesthetic, which allows patients to quickly and comfortably return to their normal activities. Also, VenaSeal® does not involve the risk of nerve injury or burning that is associated with thermal-based treatments.
Most patients do not find VenaSeal® to be painful.
Most patients report little to no bruising after the VenaSeal® procedure.
VenaSeal® is now covered for medical treatment by Medicare and a growing number of health insurance carries. Before treatment, consult your insurance company to determine whether VenaSeal® is a covered medical treatment.
VenaSeal® is performed on both men and women who suffer from significant, painful varicose veins.
