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.
Mitar Vranic, DO, founder and president of the Western Vascular Institute, has established a career treating the causes and symptoms of improper circulation, a problem that has only become exacerbated by modern sedentary lifestyles. Dr. Mitar Vranic and his associates employ advanced surgical tools and techniques to treat damaged veins and ensure their patients benefit from proper blood flow, an essential component of good health.
Because we spend many of our waking hours in upright positions, blood must flow upward against gravity to return to the heart. Usually, the strength of the heart combined with regular physical activity ensures this flow is possible, but valves in the veins are also needed to keep blood from sinking back down and pooling in the lower extremities.
If these valves function poorly because they are damaged, diseased, or occasionally even missing entirely, a lack of adequate blood flow known as venous insufficiency ensues. This can result in further complications ranging from unattractive spider veins, to painful varicose veins, to life-threatening blood clots that can break loose and lodge in other parts of the circulatory system. In the most serious cases, where the damaged valves are in large, deep veins and cannot simply be closed or removed, they can be replaced by transplanting a valve from an arm vein.
Treatments for vascular diseases can likewise range widely in their degree of intensity. Simpler treatments include regular elevation of the legs and special compression stockings designed to reinforce natural blood flow and prevent more serious conditions from developing.
Varicose veins can be treated with several forms of surgery to close those veins off, by scarring them with heat or chemical solutions, or by removing them entirely, and letting blood pass through other, deeper veins instead. Another option is a bypass, made by creating a synthetic vein or taking a vein from another part of the patient’s body and grafting it to the damaged vein, allowing blood to pass around the damaged area unimpeded.
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.
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.
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.
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.
As the founder and president of the Western Vascular Institute in Mesa, Arizona, Dr. Mitar Vranic has cared for numerous patients with varicose veins. Dr. Mitar Vranic offers radiofrequency vein closure as a treatment option.
Radiofrequency vein closure, also known as radiofrequency ablation, treats varicose veins without the hospital stay and extended recovery time of traditional vein surgery. Instead, the practicing surgeon uses radio energy to cause the vein to collapse and close. The procedure begins following the application of a low-level sedative or local anesthetic, which is given to keep the patient comfortable.
The surgeon then injects saline into the vein in order to clear the area of blood. Once the vein is clear, the surgeon introduces a small catheter into the vein, where radiofrequency energy generates heat, which in turn causes the vein to shrink. As the vein walls collapse and come together, the vein closes. Most patients can walk out of the medical office following the procedure, although surgeons typically require patients to wear compression stockings for a minimum of one week after the treatment.
