How VenaSeal uses medical adhesive rather than heat to close the malfunctioning vein at the source of your symptoms, and what makes it the right choice for certain patients.
VenaSeal is a non-thermal, non-tumescent treatment for venous reflux that
closes the malfunctioning vein using a specialized medical adhesive rather
than heat. At The Vein Clinic of Dallas, every VenaSeal procedure is
personally performed by Dr. Husein Poonawala a Harvard-trained vascular and interventional radiologist with double board certification in venous and
lymphatic medicine. Whether VenaSeal or another treatment is most
appropriate for your anatomy is determined after a thorough diagnostic
evaluation, never before it.
VenaSeal is an FDA-approved closure system that treats chronic venous insufficiency , the underlying condition responsible for varicose veins , leg heaviness, aching, swelling , and the progressive skin changes associated with advanced venous disease.
Like radiofrequency ablation, VenaSeal works by closing the malfunctioning
vein generating pressure in the lower legs. The fundamental difference is the
mechanism. Instead of using heat, VenaSeal delivers a small amount of
medical-grade cyanoacrylate adhesive at precise intervals along the vein wall,
bonding it closed. The treated vein is then gradually absorbed by the body
while blood reroutes naturally through healthy adjacent vessels. The result is
the same: elimination of reflux, relief from symptoms, and restoration of
healthy circulation. The experience of getting there is meaningfully different.
30–45 minutes
Single entry-point local only
Same-day return to activity
Coverage varies by carrier
Not required in most cases
VenaSeal is recommended when a diagnostic duplex ultrasound confirms venous reflux
and the clinical and anatomical picture makes it the most appropriate treatment choice.
Patients who want to avoid tumescent anesthesia, which requires multiple needle injections along the length of the vein
Patients with a lower pain threshold or needle sensitivity who would benefit from a single-entry-point approach
Patients who prefer to avoid post-procedure compression stockings, which are not required after VenaSeal in most cases
Veins in locations where the absence of thermal energy reduces procedural risk
Confirmed reflux in the great saphenous vein, small saphenous vein, or accessory veins where anatomy and clinical picture support VenaSeal
VenaSeal is performed under continuous duplex ultrasound guidance from start to finish,
with precise adhesive delivery monitored in real time.
A single entry point is numbed with a small amount of local anesthetic. No tumescent anesthesia is required along the length of the vein.
A thin catheter is introduced into the malfunctioning vein through the numbed entry point under continuous ultrasound guidance.
Small, precisely placed amounts of medical-grade cyanoacrylate adhesive are delivered at key intervals along the vein wall under ultrasound guidance.
The adhesive bonds the vein walls together, permanently sealing the vessel closed. No heat, no tumescent anesthesia, and no surgical incision are required.
Blood flow reroutes to healthy adjacent veins as soon as the vessel is sealed, restoring efficient circulation.
The sealed vein is gradually absorbed by the body over the following weeks and months, leaving no residual vessel.
Gradual fading. Lasting clearance.
Significant improvement in leg heaviness, aching, swelling, and discomfort typically begins within days as pressure in the closed vein is eliminated
Visible varicose veins overlying the treated vessel gradually flatten and fade over several weeks as circulation normalizes
No compression stockings required post-procedure in most cases, which many patients find a meaningful practical advantage
Treated vein is permanently sealed with long-term closure rates comparable to thermal ablation in published clinical studies
VenaSeal is FDA-approved, but insurance coverage varies by carrier and plan. Some major insurers cover it fully when medical necessity is established. Others may not cover it even when reflux is confirmed, in
which case fully covered alternatives will be discussed with you. Our team verifies your specific coverage before your visit and will walk you through your options clearly so you can make an informed decision.
Plans accepted include BCBS, Anthem, Medicare, Aetna, Cigna, United
Healthcare and more.
VenaSeal has an excellent safety profile and avoids the thermal energy used in RFA, eliminating the small risk of heat-related nerve sensitivity. Mild bruising or local tenderness may occur and typically resolves quickly. Allergic reactions to the cyanoacrylate adhesive are exceedingly rare.
Dr. Poonawala personally performs every VenaSeal procedure under continuous ultrasound guidance. His background in vascular and interventional radiology means precise catheter control and real-time image interpretation at every step.
VenaSeal is offered when evaluation confirms it is the most appropriate treatment for your specific anatomy and goals, not as a blanket alternative to thermal procedures.
If VenaSeal is not covered by your plan, we will tell you clearly and discuss the options that are.
Your VenaSeal procedure is the beginning of a monitored care relationship. Annual follow-up evaluations ensure your results are protected and any new disease is detected early.
If your legs feel heavy by the end of the day, ache after standing, swell around the ankles,
or have developed visible varicose veins, a comprehensive vein evaluation will determine
whether VenaSeal or another treatment is the right approach for your anatomy and goals.
