As founding medical director of Virginia Vein Care, Lawrence J. Markovitz, MD, builds on extensive experience treating various forms of vein disease. Dr. Lawrence J. Markovitz, an MD graduate of the Mount Sinai School of Medicine, has investigated many types of venous insufficiency treatment and has found the Venefit procedure to be among the most effective.
Once known as the VNUS Closure procedure, Venefit treatment offers relief for many patients with varicose veins and chronic venous insufficiency (CVI). These conditions occur as a result of valve malfunction in the leg veins, which lose the ability to pump blood back to the heart properly. The blood instead pools in the legs, ultimately causing such symptoms as swelling, pain, fatigue, and even ulcers or changes in the skin.
Venefit helps patients to avoid these symptoms by closing the damaged veins. The procedure uses a proprietary radio-frequency ablation technique, delivered via a catheter, to heat the collagen that grows in the vein walls. This controlled heat causes the vein to collapse and close. Most often performed under local anesthesia, the procedure takes approximately 30 minutes. Patients can typically return to normal levels of activity within a day.
