The Journal of Vascular & Interventional Radiology, the prestigious monthly publication of the Society of Interventional Radiology, has published a study showing the VNUS ClosureFAST™ system for radio frequency thermal ablation to be "significantly superior" to endovenous laser for treating venous reflux, the underlying cause of symptomatic varicose veins.
The VNUS ClosureFAST catheter is a minimally invasive device generally used in the physician's office with a local anesthetic to heat and seal the great saphenous vein, the most common site of venous reflux in the leg. The study covering 87 vein ablation procedures in 69 patients, compared the ClosureFAST radiofrequency catheter to the 980 nm endovenous laser system.
The study found that the ClosureFAST radiofrequency catheter was statistically superior to laser treatment in providing a fast and comfortable recovery for the patient after treatment. Specifically, radiofrequency vein ablation using the ClosureFAST catheter was shown to result in less postoperative pain, less bruising, less tenderness, and better reduction of symptoms than laser as soon as two days after treatment, and remaining considerably better for at least two weeks or longer. Minor complications were five times less prevalent.
"The study confirms what many of us who have used both laser and radiofrequency devices have felt subjectively - that there is significantly enhanced patient comfort with the radiofrequency technology," said Raymond G. Makhoul, M.D., of Richmond, Virginia, a researcher for the study. "The ClosureFAST device clearly provided a superior patient experience."
