As founding medical director of Virginia Vein Care, Lawrence J. Markovitz, MD, performs a number of corrective procedures for patients with varicose veins. Dedicated to the use of minimally invasive options, Dr. Lawrence J. Markovitz performs endovenous laser treatment (EVLT) as well as radiofrequency ablation (RFA).

Both EVLT and RFA treat varicose veins by heating the vessel to a level that damages its structure. RFA uses radiofrequency energy that shrinks the collagen inside the vein wall, so that the vein itself shrinks to the degree that the walls meet and close. EVLT introduces laser heat that injures the vein, which then grows scar tissue that meets to close the vein.

Both procedures take place using a catheter, which the physician passes through a small incision into the vein. Because the procedure is minimally invasive, patients typically experience less pain than those who undergo traditional vein surgery. Procedures are typically ambulatory and involve a short recovery period.

EVLT is effective in approximately 94 percent of patients, while RFA has an 95 percent effectiveness rate. Should a vein fail to close, the patient may undergo the same treatment again or opt for an alternative.

Risk Factors for Varicose Veins

Lawrence J. Markovitz, MD, has served as the medical director of Virginia Vein Care since 2008. In that time, Lawrence J. Markovitz, MD, has focused on performing minimally invasive procedures to treat varicose veins and other vein conditions.

In a normally functioning leg vein, valves permit the flow of blood up toward the heart and close to prevent backward flow. When these valves cease to function or function abnormally, however, blood begins to pool in the leg and can cause the vein to twist or swell. Statistically, this occurs more often in older individuals, as age can weaken the vein walls and prevent valves from closing properly.

Pregnancy is also a risk factor for varicose veins, because it lessens blood flow from the legs to the pelvic region while increasing overall blood volume. When this occurs, an excess of blood in the legs can cause the veins to swell. Pregnancy hormones may also weaken the vein walls, as may the hormones of premenstruation and menopause. These factors may contribute to the significantly higher rate of varicose veins in women as compared to men.

Other risk factors for varicose veins include a family history of the condition and a congenital predisposition to valve malfunction. Those with a personal medical history of blood clots in the lower extremities may have a higher predisposition as well. Finally, obese patients and those who sit or stand for extended periods may also be at greater risk of developing varicose veins during their lifetimes.

Side Effects of Venous Insufficiency

Lawrence J. Markovitz, MD, founded and serves as the medical director of Virginia Vein Care. In this role, Dr. Lawrence Markovitz, who obtained his MD from the Mt. Sinai School of Medicine, helps patients to understand vein disease and its risks to health and comfort.

When the valves that control blood flow in the leg veins begin to fail, a condition known as venous insufficiency, blood can begin to collect in the legs and feet. This can cause a number of secondary issues, which range from aesthetic to life-threatening. Many patients express concern about the varicose and spider veins that signal venous insufficiency. These are not only cosmetically undesirable, but are also causes of pain, fatigue, and throbbing sensations in the legs.

In some cases, pooling of blood in the legs can cause scarring and pigmentation changes near the ankles. Furthermore, approximately 1 percent of patients over 60 develop skin ulcers, which resist healing due to blood backup. Some individuals with venous insufficiency may also be at risk of either superficial or deep blood clots. Clotting of both types may cause swelling and discomfort, though a deep vein clot poses a greater danger, as it can travel to the lungs and is potentially fatal.

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.
