Utilizing radiofrequency ablation, alternatively known as ClosureFast, varicose veins in the lower extremities are efficiently treated. The method is minimally invasive and produces favorable outcomes. A physician frequently chooses the larger saphenous vein and the smaller saphenous vein when administering vascularized treatment. Pressure can be reduced in the veins and varicose veins of the lower extremities through the closure of the problematic veins. By employing electrical current, ClosureFast efficiently treats venous insufficiency and varicose veins. Given the irreversible nature of leg valves, rerouting blood flow from the afflicted muscle to the unaffected muscle is the most appropriate course of action.

To obviate the need for major surgical incisions, the act of closing the troublesome vein diminishes blood flow, emulating the outcome of vein stripping. The ClosureFast procedure may be safely and effectively performed by making a tiny incision in the lower thigh and using a topical anesthetic. Typically, the skin access point will be narrower than 3mm. Having ClosureFast done at a doctor’s office usually takes around half an hour. The only necessary preparation for the operation is a local anesthetic. Patients are usually allowed to leave the hospital and go back to work the same day after the treatment is finished. In order to isolate the injured vein during surgery, radiofrequency radiation is used to reroute blood flow to healthy limb veins.

How ClosureFast procedure works?

The valves in the legs are irreparable. Hence, the only feasible therapy is to divert the blood flow from the damaged veins to the unaffected ones. A catheter is introduced into the afflicted vein via a small incision created right below the patella using surgical techniques. The vein is treated in 7 cm segments, guided by ultrasound imaging, for 20 seconds each. The catheter delivers steady and even heat to cause collagen contraction in the vein’s walls, leading in collapse and eventual closure. By occluding the vein, blood flow is redirected to undamaged veins. Following therapy, the vein develops fibrosis and gradually integrates with the surrounding muscle tissue. ClosureFast has been found to provide higher closure rates while reducing bruising, irritation, and problems. With a treatment time of 45-60 minutes, the procedure may deliver significant cosmetic benefits, with obvious results within two weeks. Individual patients may have different outcomes.

What should I expect during my ClosureFast procedure?

Your doctor will make a small cut on your leg after giving you a topical anesthetic. The ClosureFast catheter is inserted into a vein after a little incision is made. After that, the sick vein is located by manipulating the catheter to its end while using ultrasound imaging.

Your healthcare professional will inject a local anesthetic around the vein before inserting radiofrequency radiation into the vein walls. The next step is to place the catheter into the vein that has not yet been treated, and then to give another radiofrequency pulse. They will continue in this way until they have treated every vein in your body.

Difference between ClosureFast and Vein stripping

Vein stripping is one kind of surgical therapy. After the surgeon has tied off the vein using an incision in the groin, a second incision is performed just above the calf to extract it. The leg vein is then extracted using a “stripper” tool.

Following a vein treatment, patients often experience bruising and swelling. In rare instances, damage to the nerve tissues around the treated vein may result in regional burning or numbness.

The incision is hardly noticeable now that ClosureFast has been used. A little surgical cut is performed behind the knee to introduce a specialized catheter that closes the vein without extracting it, in contrast to vein removal. Vein stripping is often performed in an operating room, with the patient under general anesthesia. In contrast, ClosureFast procedures are mostly performed in an outpatient clinic, with the patient under the influence of local or regional anesthetic.
