What is Venefit™ targeted endovenous therapy?  


The Venefit procedure is a minimally invasive  catheter-based treatment option that uses radiofrequency (RF) energy to effectively treat patients suffering from varicose veins or chronic venous insufficiency (CVI). Dr. Brennig guides and places the ClosureFast™ catheter into the diseased vein to provide targeted heat to contract the collagen in the vein walls, causing the vein to shrink and seal closed. Once the diseased vein is closed, blood will re-route itself to other healthy veins known as collateral veins.

How is the Venefit™ procedure different from vein stripping?  

During vein stripping, incisions are made in the groin and calf, and a tool is threaded through the diseased vein to pull the vein out of the leg. With the Venefit™ procedure, only one small incision is made at the insertion site and the vein is then treated and left in place. This minimally invasive approach reduces the likelihood of pain and bruising.1,2

How is the Venefit™ procedure different from endovenous laser?  

The Venefit™ procedure and endovenous laser ablation are both minimally invasive procedures, a comparative, multi-center study showed that the Venefit™ procedure was associated with statistically significant lower rates of pain, bruising and complications. Patients undergoing the Venefit™ procedure also reported improvements in quality of life measures up to four times faster than patients treated with endovenous laser ablation (the study was conducted with a 980nm laser).
Dr. Brennig uses one of the latest 1410 nm endovenous ablation lasers available.   This laser is associated with much less discomfort than the traditional 980 nm lasers.  The decision whether to recommend the benefit procedure or endovenous laser treatment is based upon clinical factors which Dr. Brennig discusses with each patient on an individual basis. Both techniques have excellent results and excellent safety profiles when performed by an experienced expert.

How long does the Venefit™ procedure take?  

The Venefit™ and EVLT procedures both take approximately 45-60 minutes.  Normal activity may be resumed immediately following the procedure.

Is the Venefit™ procedure painful?  

Most patients report feeling little, if any, pain during the Venefit™ procedure.3   Your physician should  give you a local or regional anesthetic to numb the treatment area.

Does the Venefit™ procedure require anesthesia?  

The Venefit™ procedure is usually performed using local anesthesia similar to the lidocaine used by your dentist. No general anesthetic or sedation is required.

How quickly after treatment can I return to normal activities?  

The same day.

How soon after treatment will my symptoms improve?  

Results vary depending upon the extent of vein disease and how long the veins have been affected. Most patients report a noticeable improvement in their symptoms within 1-2 weeks following the procedure.3

Is there any scarring, bruising or swelling after the Venefit™ procedure?  

Patients report limited to no scarring, bruising or swelling following the Venefit™ procedure.

What potential risks and complications are associated with the Venefit™ procedure?  

As with all medical procedures, potential risks and complications exist and include vessel perforation, deep vein thrombosis (DVT), pulmonary embolism (when a blood clot travels to the lungs), phlebitis (inflammation of the vein), infection, nerve damage, arteriovenous fistula (an abnormal connection between an artery and a vein), hematoma (bruising), and skin burn. As with all medical procedures, consult your physician to understand the risks and benefits of the procedure.  Dr. Brennig has personally performed well over 2000 catheter-based saphenous vein ablations with 0% of patients having developing DVT (All treated patients were analyzed post-treatment at least once with ultrasonography in order to rule out presence of DVT)

Is the Venefit™ procedure suitable for everyone?  

Dr. Brennig will determine if the Venefit™ procedure is the right option for your vein problem.

How effective is the Venefit™ procedure?  

The Venefit™ procedure has been shown in a large international, multi-center study to be 93% effective over three years.

Is the Venefit™ procedure covered by my insurance?

Like most procedures necessary for the treatment of clinically significant varicose veins, the Venefit™ procedure in part or in full usually covered. The Venefit™ procedure has coverage policies with major health insurers.
