VenaSeal™ (Cyanoacrylate Vein Closure)

VenaSeal™ Vein Closure in Sarasota & Bradenton


No Heat. No Numbing Injections Along the Leg. Often No Stockings.

VenaSeal™ closes a diseased vein using a small amount of medical adhesive rather than heat or medication. Through a catheter about the width of a strand of spaghetti, your physician places precise droplets of the adhesive along the inside of the vein while applying gentle pressure from the outside. The vein walls are held together until they bond and seal. Blood immediately reroutes into healthy veins, and over time the sealed vein becomes scar tissue that the body absorbs.

The FDA approved VenaSeal in February 2015 for the permanent closure of superficial truncal veins, such as the greater saphenous vein, through endovascular embolization with coaptation. The long-term data are reassuring: in the five-year extension of the VeClose randomized trial, which compared adhesive closure against radiofrequency ablation, 94.6 percent of veins treated with the adhesive remained closed at sixty months.

What patients notice most is what the procedure skips. Because there is no heat, there is no need for tumescent anesthesia — the ring of numbing injections placed up and down the leg to shield surrounding tissue from thermal energy. There is only one numbed access point. And in most cases, no compression stockings are required afterward.

What VenaSeal Treats

  • Incompetent greater saphenous veins
  • Incompetent small saphenous veins
  • Incompetent accessory saphenous veins
  • Symptomatic varicose veins caused by reflux in these veins — aching, heaviness, swelling, night cramps, restlessness, and skin changes at the ankle

Who VenaSeal Suits Particularly Well

Every vein closure method has a patient it fits best. VenaSeal tends to be the right answer in three situations.

The first is patients who cannot reliably wear compression stockings. Arthritic hands, limited shoulder motion, reduced mobility, or simply living alone can make daily stockings unrealistic, and a treatment plan that depends on something a patient cannot physically do is not a good plan. Clinicians working with the adhesive have specifically noted its suitability for older patients with other medical conditions, advanced vein disease, and reduced mobility who cannot manage compression.

The second is veins that run close to a nerve. Heat-based treatment near a nerve carries a risk of nerve irritation or injury. Adhesive closure generates no heat, so that particular risk is removed.

The third is patients who need to be back on their feet immediately — no restrictions, no stockings, no recovery window to plan around.

What to Expect

An ultrasound maps the vein and confirms the plan. A single access point below the knee or at the calf is numbed. Your physician advances a thin catheter into the vein under ultrasound guidance, then withdraws it in small steps, placing adhesive and applying external pressure as it comes back. You may feel mild pressure or a pulling sensation, but not the burning or stinging associated with heat.

The procedure generally takes thirty to forty-five minutes. A small bandage covers the access site. Most patients drive themselves home, return to work the same or next day, and resume walking immediately. Your physician will confirm whether compression is needed in your particular case. A follow-up ultrasound checks that the vein has closed.

Frequently Asked Questions

  • Is it safe to leave adhesive inside my leg? +

    The adhesive is a medical-grade material used elsewhere in medicine for closing blood vessels and tissue. It stays in place, seals the vein, and is gradually replaced by scar tissue as the body absorbs the vein. Five-year follow-up from the randomized trial that supported FDA approval found the closures held and no new safety concerns emerged over that period.

  • Do I really not need compression stockings? +

    In most cases, no. That is one of the main practical differences between adhesive closure and heat-based treatment. Your physician will make the call based on your specific situation — if you have significant swelling or skin changes, compression may still be recommended for reasons beyond the vein closure itself.

  • How does VenaSeal compare to radiofrequency ablation? +

    They were compared directly in a randomized trial. Adhesive closure was found to be non-inferior to radiofrequency ablation, meaning it worked as well, with high closure rates sustained out to five years in both groups. The practical differences are the ones that matter to most patients: adhesive closure avoids the numbing injections along the leg, avoids heat near nerves, and usually avoids compression stockings.

  • Will my insurance cover VenaSeal? +

    This is the question to ask before scheduling, because coverage for adhesive closure is less consistent than for heat-based treatment. Some plans cover it under the same criteria as other vein closure procedures; others require additional documentation, and a few still classify it as investigational and decline it. Our staff verifies your specific benefits and pursues prior authorization before you are scheduled. If your plan will not cover it, we will tell you that and discuss the alternatives — including treatments that are covered.

  • What are the risks? +

    The most commonly reported effect is a temporary inflammatory reaction along the treated vein — redness, tenderness, or an itchy rash in the skin over the vein — which usually settles with time and, if needed, an over-the-counter antihistamine or anti-inflammatory. Bruising and tenderness at the access site are common. Less commonly, a clot can extend into a deeper vein. Patients with a known allergy to cyanoacrylate adhesives should not have this procedure. Your physician will review the full list at your consultation.
