VNUS Frequently Asked Questions

What is superficial venous reflux?

Superficial venous reflux is a condition that develops when the valves that usually keep blood flowing out of your legs become damaged or diseased. This causes blood to pool in your legs. Common symptoms of superficial venous reflux include pain, swelling, leg heaviness and fatigue, as well as varicose veins in your legs.

What is the Closure procedure?

The Closure procedure is a minimally invasive treatment for superficial venous reflux. A thin catheter is inserted into the vein through a small opening. The catheter delivers thermal energy to the vein wall, causing it to heat, collapse and seal shut.

How does it work to treat superficial venous reflux?

Since valves can't be repaired, the only alternative is to re-route blood flow through healthy veins. Traditionally, this has been done by surgically removing (stripping) the troublesome vein from your leg. The Closure procedure provides a less invasive alternative to vein stripping by simply closing the problem vein instead. Once the diseased vein is closed, other healthy veins take over and empty blood from your legs.

How is the Closure procedure different from vein stripping?

During a stripping procedure, the surgeon makes an incision in your groin and ties off the vein, after which a stripper tool is threaded through the saphenous vein and used to pull the vein out of your leg through a second incision just above your calf.

In the Closure procedure, there is no need for groin surgery. Instead, the vein remains in place and is closed using a special (Closure) catheter inserted through a small puncture. This may eliminate the bruising and pain often associated with vein stripping (i.e., that may result from the tearing of side branch veins while the saphenous vein is pulled out). Vein stripping is usually performed in an operating room, under a general anesthetic, while the Closure procedure is performed on an outpatient basis, typically using local or regional anesthesia.

Will the procedure require any anesthesia?

The Closure procedure can be performed under local, regional or general anesthesia.

How quickly after treatment can I return to normal activities?

Many patients typically return to normal activities within a day.1 For a few weeks following the treatment, your doctor may recommend a regular walking regimen and suggest you refrain from very strenuous activities (heavy lifting, for example) or prolonged periods of standing.

How soon after treatment will my symptoms improve?

Most patients report a noticeable improvement in their symptoms within one to two weeks following the procedure.

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

Patients report minimal to no scarring, bruising or swelling following the Closure procedure.

Is the Closure procedure suitable for everyone?

Only a physician call tell you if the Closure procedure is a viable option for your vein problem. Experience has shown that many patients with superficial venous reflux disease can be treated with the Closure procedure.

Is the Closure treatment covered by my insurance?

Many insurance companies are paying for the Closure procedure in part or in full. Most insurance companies determine coverage for all treatments, including the Closure procedure, based on medical necessity. Your physician can discuss your insurance coverage further at the time of consultation.
