ClosureFast™ Radiofrequency Ablation

The ClosureFast™ procedure is a minimally invasive treatment that uses radiofrequency (RF) energy (uniform heat) to effectively treat patients with varicose veins or chronic venous insufficiency (CVI), a serious condition that often manifests as varicose veins. With CVI and varicose veins, the valves in the leg veins that direct blood from the legs back toward the heart no longer function properly, causing blood to pool in the legs. And because the valves in the legs cannot be repaired, the only alternative is to re‐route the blood flow from the diseased veins to the healthy veins. This unique procedure is proven effective in eliminating varicose veins and improving the appearance of the legs, allowing for a short, comfortable recovery and a quick return to everyday activities. While it’s not designed to address spider veins or cosmetic issues, ClosureFast™ procedure has been effectively used to treat both women and men across a wide range of ages.

How does ClosureFast™ radiofrequency ablation work?

The ClosureFast™ procedure takes approximately 20–30 minutes. Most patients typically spend about one hour at the medical facility due to normal pre‐ and post‐treatment procedures. It’s generally performed using local anesthesia in the surgical facility. Dr. Olson begins with inserting a catheter into the diseased vein through a tiny incision below the knee, guided by ultrasound imaging. The catheter delivers consistent and uniform heat to contract the collagen in the vein walls, causing them to collapse and close. After the vein is sealed shut, blood is then naturally redirected to healthy veins. The treated vein then becomes fibrous tissue and will gradually be absorbed into surrounding tissue.

What to expect post procedure

Many patients experience a quick return to normal activities, typically within a few days. For a few weeks following the treatment, we may recommend a regular walking regimen and suggest you refrain from very strenuous activities (i.e., heavy lifting) or prolonged periods of standing. Patients report minimal to no scarring, bruising or swelling and a noticeable improvement in their symptoms within one to two weeks following the procedure. For any cosmetic symptoms that are not completely resolved following the procedure, you may consider treatment including sclerotherapy (small chemical injections) or microphlebectomy (removal of varicose veins through small skin punctures under local anesthesia). As with all medical procedures, there is a chance that complications may occur, including, but not limited to the following: hematoma, vessel perforation, thrombosis, pulmonary embolism, phlebitis, infection, adjacent nerve injury, skin burn or discoloration.
