Radiofrequency Ablation ClosureFast™

Endovenous RadioFrequency Ablation ClosureFast™ Procedure

Varicose Vein Overview

Varicose veins are most often swollen, gnarled veins that most frequently occur in the legs, ankles and feet. They are produced by a condition known as venous insufficiency or venous reflux, in which blood circulating through the lower limbs does not properly return to the heart but instead pools up in the distended veins.

More than 25 million Americans suffer from venous reflux disease. The symptoms can include pain and fatigue in the legs, swollen ankles and calves, burning or itching skin, skin discoloration and leg ulcers. In less severe cases, thin, discolored vessels – “spider veins” – may be the only symptom.


ClosureFast™ Procedure

The ClosureFast™ procedure uses radiofrequency energy to precisely and effectively treat patients suffering from chronic venous insufficiency (CVI).

ClosureFast™ patients can walk away from the vein procedure and be back to everyday activities – either at home or at work – typically within a day.

If you suffer from varicose veins, you’re a member of a very large club. Some 25 million Americans face a daily struggle with the swollen, ropey veins that can cause throbbing pain, severe swelling, and heavy, tired legs. Please contact our office for a consultation with Dr. Evan Oblonsky.

ClosureFast™ FAQ's

How long does the ClosureFast™ Procedure take?

The ClosureFast™ procedure typically takes approximately 45-60 minutes.

Does the ClosureFast™ Procedure require anesthesia?

The ClosureFast™ procedure can be performed under local, regional or general anesthesia. It is generally performed using local anesthesia in a vein specialist’s office or an outpatient surgical facility.

After the ClosureFast™ Procedure, how quickly can I return to normal activities?

Many patients experience a quick return to normal activities, typically within a few days. For a few weeks following the treatment, a vein specialist may recommend a regular walking regimen and suggest you refrain from very strenuous activities (i.e., heavy lifting) or prolonged periods of standing.

How soon will my symptoms improve after the ClosureFast™ Procedure?

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

Can I expect any pain, bruising or tenderness after the ClosureFast™ Procedure?

Although it is possible to experience pain, bruising or tenderness after treatment, many patients report minimal to no scarring, bruising or swelling following the ClosureFast™ procedure. Speak to your physician to learn more about the ClosureFast™ procedure, its risks and outcomes.

Is the ClosureFast™ Procedure suitable for everyone?

A vein specialist can tell you if the ClosureFast™ procedure is the right option for your vein problem. Many patients with varicose veins and chronic venous insufficiency can be treated with the ClosureFast™ procedure.

Is age an important consideration for the ClosureFast™ Procedure?

The most important step in determining whether the ClosureFast™ procedure is appropriate for you is a complete ultrasound examination by a vein specialist. Age alone is not a factor in determining if the ClosureFast™ procedure is right for you. The ClosureFast™ procedure has been used to treat both women and men across a wide range of ages.

Is the ClosureFast™ Procedure covered by insurance?

Many insurance companies pay for the ClosureFast™ procedure in part or in full. The ClosureFast™ procedure has coverage policies with major health insurers. Prior to seeking treatment, consult your insurance provider to confirm coverage.

What is Radiofrequency Ablation?

Radiofrequency (RF) endovenous ablation is a minimally invasive treatment procedure for venous reflux disease, using radiofrequency to heat and seal diseased great saphenous and perforator veins and address the underlying cause of severe varicose veins. The ClosureFast™ Procedure catheter for the treatment of venous reflux delivers radiofrequency energy to a heating element to heat and contract the collagen within the vein walls and cause the shrinkage and collapse of the vessel.

The procedure involves inserting the catheter into the diseased vein through a very small incision and threading the device through the vessel up to the groin area. Radiofrequency waves are applied to the heating element in 20-second intervals to sequentially heat and ablate the vein in seven centimeter increments. After each segment is treated, the ClosureFast™ catheter is manually withdrawn down the vein and the process is repeated until the entire length of the vein has been ablated. The body automatically re-routes blood flow through healthier veins, and the restoration of normal circulation relieves the distention of the surface veins. The ablated vein becomes scar tissue and is eventually absorbed by the body.


What is the Difference Between Varicose Veins and Spider Veins?

Varicose veins and spider veins are both visible surface symptoms of venous insufficiency, the inability of diseased leg veins to push blood back up towards the heart. The surface veins become distended and prominent because blood that should normally circulate through the body is instead accumulating in the legs.

Varicose Veins

Varicose veins are a medical condition, larger and more serious manifestations of venous reflux disease. The swollen vessels can protrude several millimeters beyond the skin surface and can become knotted and tangled. Varicose veins are frequently accompanied by clinical symptoms such as pain, throbbing, burning sensations, muscle cramps and fatigue, and can progress to leg ulcers, blood clots and other health-endangering conditions.

Spider Veins

Spider veins are thin surface veins that turn blue or red under the strain of the venous reflux and affect the appearance of the location where they occur. Spider veins are considered a cosmetic problem, rarely causing physical discomfort, and can be addressed with a variety of non-invasive, techniques.
