Radiofrequency Closure for Varicose Veins

As a practitioner with Western Vascular Institute, Dr. Mitar Vranic builds on two decades of experience in vascular surgery. Dr. Mitar Vranic applies this experience in performing radiofrequency closure and other procedures that treat varicose veins.

Radiofrequency closure, also known as radiofrequency ablation, addresses the venous reflex disease that often causes varicose veins. It serves as an alternative to traditional vein stripping, which requires invasive surgical removal of the diseased veins. Instead, radiofrequency ablation uses laser energy to prompt the closure of diseased veins.

The surgeon starts by numbing the area with a topical and local anesthetic. Then, by way of a small incision, he or she passes a catheter or similar tool into the affected vein. The catheter serves as a channel through which the surgeon introduces an electrode or laser fiber.

When the surgeon pulls back on the catheter to expose the end of the fiber or electrode, energy passes into the vein as heat. This heat shrinks the collagen in the vein wall, which in turn causes the vein to shrink and close. The surgeon then removes the catheter and the patient’s body proceeds to heal the closure by rerouting blood to healthy veins.

Patients typically resume normal activity the same day and see results in only a few days. For 95 percent of these individuals, success is lasting.


Symptoms of Klippel-Trenaunay Syndrome

As a surgeon at Western Vascular Institute, Dr. Mitar Vranic draws on almost two decades of specialized experience. Over this time, Dr. Mitar Vranic has provided care to individuals with Klippel-Trenaunay syndrome.

A rare genetic condition, Klippel-Trenaunay syndrome is characterized by abnormal growth of blood vessels, bone, and soft tissue. The majority of patients with the syndrome present at birth with a red-purple birthmark, which typically appears on a leg and stems from the swelling of small vessels near the skin’s surface. In some patients, the birthmark develops small blisters that are prone to bleeding.

Vascular abnormalities caused by the syndrome may also include varicose veins, which most often form on the legs and close to the skin’s surface. Some patients do develop varicosity of the deeper leg veins, a complication that can lead to a variety of blood clot known as deep vein thrombosis. These clots are particularly dangerous as they can dislodge from the leg and travel through the bloodstream to the lungs, where they can result in pulmonary embolism.

Patients with Klippel-Trenaunay syndrome are also prone to excessive growth of the soft tissues and bones. This growth typically affects only one leg, though some patients experience the same issue in the arms and occasionally in the torso. Symptoms include pain, a feeling of heaviness, and restricted movement, as well as potential uneven leg growth that can inhibit comfortable walking.

Uses for Ultrasound Diagnostics

Mitar Vranic, DO, is an osteopathic surgeon at Western Vascular Associates in Mesa, Arizona, focusing primarily on vascular surgery, Dr. Mitar Vranic is board-certified in several fields, and also holds certification in the use of ultrasound diagnostics.

Ultrasound uses high-frequency sound waves inaudible to humans. A computer displays the results of these sound waves as images of organs and tissue.

This technique is often associated with imaging unborn children. Ultrasound in pregnancy can reveal the presence of twins, detect ectopic pregnancies, and the gender of the fetus. It can also spot some birth defects and give an idea of size and weight.

Ultrasound is useful in other situations as well, though. It can visualize problems with blood vessels, the heart, kidneys, liver, and other organs. However, dense bone and the presence of gas or air inside certain organs hinders ultrasound’s capabilities.

Diagnosticians also employ ultrasound to guide them to the proper area during needle biopsies. Ultrasound waves can also be used as a treatment, by making repairs to soft tissue injuries.
