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.
