Causes and Consequences of Venous Insufficiency

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.


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.

Radiofrequency Closure for Varicose Veins

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.

Common Causes of Varicose Veins

A vascular surgeon in Mesa, Arizona, Mitar Vranic is the founder of Western Vascular Institute, PLLC. In addition to treating a variety of vascular diseases, Mitar Vranic and his partner Dr. Henry Tarlian treat varicose veins using techniques such as advanced radio frequency, a less painful alternative to surgery or vein ligation.

Varicose veins are swollen veins visible just under the surface of the skin. While they typically cause few symptoms or trouble, they can sometimes lead to moderate pain, blood clots, skin ulcers, and other problems. Age is one common factor contributing to varicose veins; as skin ages, veins lose their elasticity, causing blood to pool and veins to become enlarged.

Pregnant women may also experience varicose veins, as pregnancy causes an increase in blood volume and a decrease in blood flow from the legs to the pelvis. Additionally, changing hormone levels may affect the appearance of varicose veins.
