VenaSeal™ Vein Treatment for Varicose Veins

VenaSeal™ (Medtronic) is an advanced, minimally invasive vein treatment that uses a medical adhesive (cyanoacrylate) to close unhealthy veins and improve blood flow. At BASS Vein Center, our board-certified specialists perform VenaSeal™ as a comfortable outpatient procedure with no heat, no tumescent anesthesia, and no need for compression stockings after treatment. This procedure is ideal for patients seeking a fast, effective, and virtually painless solution to symptomatic varicose veins.

What Is the VenaSeal™ Closure System?

VenaSeal™ is an FDA-approved treatment that seals diseased veins using a small amount of a medical-grade adhesive.
Once the targeted vein is sealed, blood is naturally rerouted to healthy veins, relieving symptoms such as:

  • Leg heaviness or fatigue
  • Aching or throbbing
  • Swelling
  • Visible bulging veins
  • Skin irritation or discoloration

Because VenaSeal™ does not use heat (unlike laser or radiofrequency), it reduces the risk of thermal injury and eliminates the need for multiple injections of local anesthesia.

How VenaSeal™ Works

The VenaSeal™ procedure is performed in our office and typically takes 30–45 minutes. Here’s what to expect:

  1. Ultrasound Mapping – Your vein specialist identifies the diseased vein using real-time ultrasound imaging.
  2. Catheter Placement – A very small catheter is inserted into the vein through a single needle entry point.
  3. Adhesive Delivery – A controlled amount of medical adhesive (cyanoacrylate) is delivered along the vein.
  4. Sealing the Vein – Gentle pressure is applied to help the vein walls seal together.
  5. Rerouting Blood Flow – Blood instantly reroutes to healthy veins nearby, restoring proper circulation.

Patients can walk immediately after the procedure and resume normal daily activities right away.

What Are Cyanoacrylates?

Cyanoacrylates are medical adhesives that have been used for decades in:

  • Emergency wound closure
  • Cosmetic procedures
  • Dental and ophthalmic surgeries
  • Orthopedic care
  • Treatment of vascular malformations (AVMs)

In VenaSeal™, a specialized intravascular formulation is used to safely seal problematic veins.
This adhesive becomes firm over time, forming a thin cord within the vein, which remains harmlessly in place as the body adapts.

Benefits of VenaSeal™

Patients often choose VenaSeal™ because it offers:

  • No tumescent anesthesia (no multiple numbing injections)
  • No compression stockings required afterward
  • Minimal discomfort during and after the procedure
  • No heat → no risk of thermal injury or nerve damage
  • Immediate return to normal activities
  • No hospital or surgery center required

VenaSeal™ is one of the most comfortable vein treatments available today.
