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.


Hyperbaric Oxygen Therapy

A vascular surgeon with Western Vascular Institute in Mesa, Arizona, Dr. Mitar Vranic has board certification in vascular and general surgery and in wound care. Moreover, Dr. Mitar Vranic has received training from the Undersea and Hyperbaric Medical Society (UHMS), a source of medical and scientific information regarding hyperbaric oxygen therapy.

Used to treat decompression sickness (a condition that affects scuba divers), hyperbaric oxygen therapy is also effective for addressing serious infections and wounds that have arisen as a result of conditions such as diabetes or radiation injury. It can also be employed to treat conditions such as carbon monoxide poisoning and gas gangrene and to encourage the healing of skin grafts.

Hyperbaric oxygen therapy involves inhaling pure, pressurized oxygen in a sealed hyperbaric chamber. Because the air pressure within the chamber is roughly 2.5 times higher than normal atmospheric pressure, the blood carries more oxygen to the body’s tissues and organs. The relatively high oxygen concentration of the blood facilitates faster healing.

Aneurysms – A Condition of Weakened or Ruptured Arteries

Dr. Mitar Vranic heads Western Vascular Institute and provides patients with experienced care for a wide range of vascular issues, from strokes to end-stage renal disease. Dr. Mitar Vranic also provides surgical treatment for aneurysms, which can occur in any area of the body containing blood vessels.

Partially due to a weakening of the artery wall, aneurysms are particularly likely to develop in areas of strong pressure, such as where blood vessels split off to various parts of the body. The vessel balloons-out or widens abnormally and threatens to rupture. The potential for aneurysms reflects a person’s family history, risk-factor behavior such as smoking, as well as high blood pressure or high cholesterol levels.

Aneurysms occurring deep within the body may not be diagnosed. Those nearer to the skin surface can be painful and involve visible throbbing and swelling and are more recognizable. One alternative to traditional open surgery involves repairing the aneurysm through an endovascular stent graft repair. In this minimally invasive procedure, a catheter is used to place stents that help strengthen and repair the affected artery. In cases of ballooning, a coiling procedure may be employed as a way of closing off the affected area.
