For patients seeking a minimally invasive option to treat certain varicose veins, VenaSeal™ Closure offers an alternative to heat-based vein procedures. Instead of using thermal energy, VenaSeal uses a medical adhesive to close a diseased vein that is allowing blood to pool in the legs. Once the vein is sealed, blood naturally moves through healthier nearby veins, which can help reduce symptoms such as aching, swelling, heaviness, and fatigue.

Hill Country Vein Center offers VenaSeal to eligible patients in New Braunfels, TX, and the San Antonio area following a detailed vein evaluation. Dr. Mark Kneuper’s experience with office-based varicose vein management helps guide treatment selection, including when VenaSeal may be a good fit and when another minimally invasive option may be more appropriate.

What Is VenaSeal™ Closure?

VenaSeal is an office-based treatment for venous reflux disease. Venous reflux occurs when the valves inside certain leg veins stop closing properly. This allows blood to flow backward and collect in the vein, increasing pressure in the lower legs.

Over time, reflux can contribute to varicose veins, swelling, aching, heaviness, cramping, fatigue, and skin changes. VenaSeal treats the affected vein by sealing it closed with a medical adhesive. The closed vein is no longer used for circulation, and blood reroutes through healthier veins.

What Does VenaSeal™ Closure Treat?

VenaSeal may be used when an ultrasound confirms that symptoms are connected to a refluxing superficial vein. It is not the right option for every patient, which is why diagnostic evaluation is an important first step.

VenaSeal may help treat:

Varicose veins related to venous reflux
Leg heaviness, aching, or fatigue
Swelling in the lower legs or ankles
Cramping or discomfort linked to poor vein circulation
Skin irritation or discoloration related to vein pressure
Symptoms that have not improved enough with conservative care

Patients may also be evaluated for other treatments, including radiofrequency ablation, sclerotherapy, or microphlebectomy, depending on vein anatomy and symptoms.

How Does The VenaSeal™ Procedure Work?

The VenaSeal procedure is performed with ultrasound guidance. A small access point is made in the skin, and a thin catheter is placed into the diseased vein. The adhesive is delivered in controlled amounts along the vein.

The process generally includes:

Ultrasound mapping to identify the refluxing vein and plan treatment
Local numbing at the access site for comfort
Catheter placement within the affected vein
Medical adhesive delivery to seal the vein closed
Light pressure and bandaging after the catheter is removed
Follow-up guidance to support recovery and monitor results

Because VenaSeal does not use heat, it usually does not require numbing medication along the full length of the treated vein. Most patients are able to return to normal light activity shortly after the procedure, although individual instructions may vary.

The Benefits Of VenaSeal™ Closure

VenaSeal provides a minimally invasive alternative to surgical vein stripping for treating certain veins affected by reflux. The procedure is performed in the office, uses a small access point, and does not require general anesthesia.

For properly selected patients, VenaSeal may help reduce leg aching, heaviness, swelling, fatigue, and discomfort related to vein disease. Some patients also notice improvement in visible varicose veins over time as pressure in the treated vein decreases and circulation improves.

When To See A Vein Specialist

You should consider seeing a vein specialist if you have varicose veins, leg heaviness, aching, swelling, cramping, itching, or skin discoloration. Symptoms that worsen after prolonged standing or sitting may be related to venous reflux.

A vein specialist can use ultrasound imaging to determine whether a specific vein is contributing to your symptoms and whether VenaSeal is an appropriate treatment option.

Why Choose Hill Country Vein Center For VenaSeal™ Closure?

VenaSeal requires careful patient selection. The treatment works best when the correct refluxing vein is identified, and the patient’s symptoms, vein anatomy, and goals align with the procedure. Hill Country Vein Center uses ultrasound findings to guide this decision rather than relying solely on visible veins.

Dr. Mark Kneuper helps patients compare VenaSeal with other minimally invasive vein treatments, including situations in which a non-thermal adhesive closure may offer advantages. This thoughtful approach gives patients in New Braunfels, San Antonio, and surrounding communities a clearer understanding of their options before treatment begins.
