Vein Clinic

The National Center for Veins is a premier vein care center in Ashburn, VA, serving patients in Washington, D.C. and northern Virginia. Our vein clinic was founded in 2006 by Dr. Timothy Mountcastle, a double board-certified plastic surgeon, general surgeon, and medical director of Mountcastle Plastic Surgery & Vein Institute.

For more than 15 years, Dr. Mountcastle and his team have provided comprehensive vein treatments (which can be covered by insurance) to patients that range from cosmetic issues to venous diseases. Varicose veins majorly impact a person's life and our team performs more than 500 vein procedures each year. Dr. Mountcastle brings the artistry of a detail-oriented plastic surgeon with the technical skills of a vein surgeon. He is the only vein surgeon who is also a RDVPI board-certified plastic surgeon in this area. Our talented doctor is highly trained in the VNUS Closure® procedure, sclerotherapy, and the Veinwave™ treatment for spider veins.

The National Center for Veins offers minimally invasive techniques using state-of-the-art equipment in order to treat the signs and symptoms of venous disease.

Types of Vein Diseases or Conditions

Superficial Venous Reflux

Your legs are made up of a network of veins. Healthy leg veins contain valves that open and close to assist the return of blood back to the heart. Venous reflux disease develops when the valves that keep blood flowing out of the legs and back to the heart become damaged or diseased. This can cause blood to pool in your legs and lead to symptoms such as pain, swelling, swollen limbs, leg heaviness and fatigue, skin changes and skin ulcers, and varicose veins.

Spider Veins

Thread-like blood vessels seen in the skin are called spider veins. These veins, which usually branch out and enlarge, can appear anywhere on the body. Most of our patients request treatment for spider veins on the legs and face for cosmetic reasons.

Varicose Veins

Painful, unsightly varicose veins can appear under your skin as a large (¼ inch or larger in diameter) blue ropes when you have excess pressure in the saphenous system. Varicose veins branch from the saphenous trunk veins and have more than just visible symptoms. You may feel tired, have restless legs at night (or when you sleep), pain, itching, throbbing, swelling, burning, and cramping. Some patients also report feeling a heaviness in the leg. These veins can also become clotted and cause classic phlebitis.

What Causes Varicose Veins? - Dr. Mountcastle

Types of Treatment

VNUS Closure

If you are looking for an alternative to vein stripping surgery, the National Center for Veins now offers the VNUS® Closure® technology to relieve your symptoms of diseased, varicose veins and/or superficial venous reflux. Under a local or regional anesthetic, Dr. Mountcastle can perform this treatment rather quickly (less than an hour) and on an outpatient basis. With the assistance of ultrasound technology, Dr. Mountcastle will place the VNUS Closure catheter within the vein. The incision to insert the catheter will be very small. The radiofrequency energy of the VNUS Closure catheter will heat the vein wall triggering the collagen in the vein to shrink and close it off. The blood is then channeled to stronger veins.


One of the most invasive but effective methods of treating surface veins is microphlebectomy (the surgical removal of veins). We take great care to provide this surgery in our center by offering a local anesthesia. An incision is made into the skin that is so small, that stitches are usually unnecessary. Once the vein has been removed, post-operative discomfort is generally mild and you may have tiny puncture mark scars. Dr. Mountcastle will place a bandage on the treatment site, and require the patient to wear a compression stocking for a short period of time.


Another cosmetic/medical procedure to treat varicose and spider veins is sclerotherapy. Using an ultra-fine needle, Dr. Mountcastle will inject a sclerosing solution directly into your vein, which may cause discomfort or a cramping sensation for 1 – 2 minutes. The injection will cause the vein to become irritated, swell, stick together, and then clot. Your body will naturally respond to the affected vein and absorb it. You may need to have more than one injection into the vein and some return visits until the vein has disappeared. It is important to wear the support hose and/or bandage during your recovery period. Spider veins respond to sclerotherapy in 3 – 6 weeks, and larger veins will take about 3 – 4 months.

After your outpatient procedure, you will leave our center with a bandage on your insertion site and compression stockings to help with recovery. We want you to walk after the procedure to assist your body in healing, but please avoid standing for extended time periods and strenuous exercise until recommended.


Using a thermo-coagulation method, the Veinwave™ is a treatment for up to 30 cm of veins anywhere on your body. Each 15-minute session can be applied to any type of skin. Even patients with sensitive areas of the body prefer to have Veinwave treatments over injections. With no bruising or need for bandages, patients leave our center feeling and looking better after treatment.
