Radiofrequency (VENCLOSE™) Procedure
Chronic venous insufficiency (CVI) is a medical condition that affects more than 30 million Americans. Also known as venous reflux disease, CVI occurs when the valves in the veins that carry blood from the legs to the heart no longer function. Patients experience blood pooling in the legs, which causes veins to lose their form and protrude.
If you suffer from leg pain, swelling, restlessness or skin changes, such as darkening or rashes, we now offer an alternative treatment to laser ablation at our Bristol and Wallingford offices. The VENCLOSE™ system is a minimally invasive, heat-based treatment option for chronic venous insufficiency. A small catheter delivers heat to the damaged vein, causing it to shrink and close, so healthy blood flow can be restored.
How Does Radiofrequency (RF) Work?
Radiofrequency or RF begins with a tiny incision below the knee. A disposable catheter is then inserted into the damaged vein. Guided by ultrasound imaging, the doctor eases the catheter into the vein. Local anesthetic is administered around the catheter for patient comfort, to protect the surrounding tissue and to improve contact between the vein wall and catheter. Precise radiofrequency energy is delivered to the heating element within the catheter at 120° Celsius to destroy the vein wall. The collagen response closes the vein and redirects blood to nearby healthy veins. Later, the damaged vein is absorbed by the body.
What Are the Benefits?
Radiofrequency requires little to no downtime and results in minimal discomfort and bruising. Unlike surgical vein stripping, this procedure can be performed in an outpatient setting with local anesthesia. You can return to normal everyday activities that day, strenuous activities should be avoided for approximately a week following the procedure.
