Preferred Treatment for Varicose Veins and CVI

The ClosureFast™ (previously known as Venefit™) procedure is a minimally invasive treatment for varicose veins and Chronic Venous Insufficiency (CVI) in which one of the experienced doctors at Precision VIR inserts a Endovenous Radiofrequency Ablation (RFA) Catheter to collapse and close enlarged leg veins. After the vein is sealed shut, blood then naturally re-routes to healthy veins.

How Is  the ClosureFast Procedure Performed?

ClosureFast Varicose Vein TherapyA catheter is inserted into the vein through a tiny incision below the knee with under local anesthetic. In addition, lidocaine (tumescent) anesthesia is used to surround the vein to help collapse the vein around the catheter as well as provide anesthetic to reduce any discomfort. Most patients report no discomfort due to the tumescent insulating the vein during the radiofrequency treatment. Guided by ultrasound imaging, one of our physicians treats the abnormal segment of vein with radiofrequency energy, causing the vessel to shrink around the catheter. The physician withdraws the catheter, treating each segment until the entire length of the vein has been sealed.

Unlike painful vein stripping surgery or laser ablation, the catheter delivers uniform, consistent heat to each segment and temperatures do not exceed 120°C.1.The ClosureFast procedure uses controlled and consistent heat to close the diseased vein. As a result, the ClosureFast procedure causes less bruising and allows for rapid patient relief and recovery. To schedule an appointment with the experts at Precision VIR for the ClosureFast procedure, please call us at 214-382-3200 or complete the form below.

  • Minimally Invasive
  • Less Pain
  • Less Bruising
  • Faster Recovery

Excellent Clinical Outcomes

The ClosureFast catheter has been shown in a prospective, international multi-center study to be 93% effective at three years using Kaplan Meier analysis. The ClosureFast procedure is performed as a medical necessity as diagnosed by one of the vascular specialists at Precision VIR.
