About the Venefit Vein Closure Procedure

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.


A Brief Overview of Ultrasound Guided Sclerotherapy

Board-certified thoracic and cardiovascular surgeon Lawrence J. Markovitz, MD, treats patients at Virginia Vein Care in McLean, Virginia. A highly skilled physician, Dr. Lawrence Markovitz has experience performing a wide range of procedures, including endovenous laser treatment, radiofrequency ablation, and ultrasound guided sclerotherapy.

A minimally invasive procedure, ultrasound guided sclerotherapy (UGS) is a technique used to treat a variety of venous conditions, including varicose veins, leg ulcers, and venous eczema. During the procedure, a physician uses ultrasound to diagnose deep leakages of blood, also known as reflux, that cause veins to dilate and become varicose. He or she then treats the leakages with guided injections into problem areas.

UGS is a quick procedure that typically takes anywhere from 15 minutes to 30 minutes to complete. It is frequently performed after endovenous ablation procedures have treated larger veins. After undergoing the procedure, patients can return to their normal activities the same day. Although it is usually quite effective at eliminating diseased veins, UGS may sometimes requires several sessions and several weeks before veins become final results are achieved.

Lawrence J. Markovitz, MD – Untreated Vein Disease

Lawrence J. Markovitz, MD, the former chairman of thoracic and cardiovascular surgery with the Luther Midelfort Mayo Health System, tends to patients with a variety of venous conditions. Currently practicing at the Virginia Vein Care clinics in McLean and Purcellville, Virginia, Lawrence J. Markovitz, MD, concentrates on providing minimally invasive treatment of vein disease.

While some may consider varicose and spider veins to be primarily a cosmetic concern, leaving these conditions untreated can, over time, cause greater medical issues. Three common disorders related to venous reflex are leg swelling, skin changes, and venous ulcers.

1. Leg Swelling. Also known as edema, leg swelling often indicates circulation problems. Damaged veins make it more difficult for blood to return to the heart. Some blood may remain in the lower leg, causing venous hypertension and swelling.

2. Skin Changes. Inadequate blood flow and the resulting increased pressure can also change the color of the leg. Along with this hyperpigmentation, the skin’s texture may be altered as well.

3. Venous Ulcers. More dangerous than the other two conditions, venous ulcers are wounds forming near the ankle. Venous ulcers occur in patients due to damaged veins. While some patients may be treated conservatively, others require more intensive, though still minimally invasive, procedures.
