Varicose Veins

What are varicose veins?

Arteries bring oxygen-rich blood from your heart to the rest of your body and veins return oxygen-poor blood back to your heart.

Varicose veins are swollen veins that you can see through your skin. They often look blue, bulging, and twisted. Left untreated, varicose veins may worsen over time. Varicose veins can cause aching and feelings of fatigue as well as skin changes like rashes, redness, and sores. As many as 40 million Americans, most of them women, have varicose veins.

You have three kinds of veins in your legs; the superficial veins, which lie closest to your skin, the deep veins, which lie in groups of muscles and perforating veins, which connect the superficial veins to the deep veins. The deep veins lead to the vena cava, your body’s largest vein, which runs directly to your heart. Varicose veins occur in the superficial veins in your legs.

When you are in the upright position, the blood in your leg veins must work against gravity to return to your heart. To accomplish this, your leg muscles squeeze the deep veins of your legs and feet. One-way flaps, called valves, in your veins keep blood flowing in the right direction. When your leg muscles contract, the valves inside your veins open. When your legs relax, the valves close. This prevents blood from flowing in reverse, back down the legs. The entire process of sending blood back to the heart is called the venous pump.

When you walk and your leg muscles squeeze, the venous pump works well. But when you sit or stand, especially for a long time, the blood in your leg veins can pool and the pressure in your veins can increase. Deep veins and perforating veins are usually able to withstand short periods of increased pressures. However, if you are a susceptible individual, your veins can stretch if you repeatedly sit or stand for a long time. This stretching can sometimes weaken the walls of your veins and damage your vein valves. Varicose veins may result. Spider veins are mild varicose veins. They look like a nest of red or blue lines just under your skin. Spider veins are not a serious medical problem, but they can be a cosmetic concern to some people, and they can cause symptoms of aching pain and itching in others.

What are the symptoms?

If you have varicose veins, your legs may feel heavy, tired, restless, or achy. Standing or sitting for too long may worsen your symptoms. You may also experience night cramps.

You may notice small clusters of veins in a winding pattern on your leg, or soft, slightly tender knots of veins. Sometimes, the skin on your legs may change color, become irritated, or even form sores.

If you have severe varicose veins, you have slightly increased chances of developing deep vein thrombosis (DVT). DVT may cause leg pain and swelling, and in some cases, sudden death from a pulmonary embolism (PE). DVT is a serious condition that requires immediate medical attention.

What causes varicose veins?

High blood pressure inside your superficial leg veins causes varicose veins.
Factors that can increase your risk for varicose veins include having a family history of varicose veins, being overweight, not exercising enough, standing or sitting for long periods of time, or having DVT. Women are more likely than men to develop varicose veins. Varicose veins usually affect people between the ages of 30 and 70.

Pregnant women have an increased risk of developing varicose veins, but the veins often return to normal within 1 year after childbirth. Women who have multiple pregnancies may develop permanent varicose veins.

What tests will I need?

First, Dr. Robbins asks you questions about your general health, medical history, and symptoms. In addition, he conducts a physical exam. Together these are known as a patient history and exam. Dr. Robbins will examine the texture and color of any prominent veins. He may apply a tourniquet or direct hand pressure to observe how your veins fill with blood. To confirm a diagnosis of varicose veins, Dr. Robbins may order a duplex ultrasound test.

Duplex ultrasound uses painless, high-frequency waves higher than human hearing can detect. Our Vascular Technologist uses duplex ultrasound to measure the speed of blood flow and to see the structure of your leg veins. The test can take approximately 20 minutes for each leg. Besides showing varicose veins, duplex ultrasound may help Dr. Robbins decide whether your varicose veins could be related to some other condition rather than the veins themselves.

How are varicose veins treated?

Varicose veins may sometimes worsen without treatment. Dr. Robbins will first try methods that don’t require surgery to relieve your symptoms. If you have mild to moderate varicose veins, elevating your legs can help reduce leg swelling and relieve other symptoms. Dr. Robbins may instruct you to prop your feet up above the level of your heart 3 or 4 times a day for about 15 minutes at a time. When you need to stand for a long period of time, you can flex your legs occasionally to allow the venous pump to keep blood moving toward your heart.

Compression Stockings

For more severe varicose veins, Dr. Robbins may prescribe compression stockings. Compression stockings are elastic stockings that squeeze your veins and stop excess blood from flowing backward. In this way, compression stockings also can help heal skin sores and prevent them from returning. You may be required to wear compression stockings daily for the rest of your life. For many patients, compression stockings effectively treat varicose veins and may be all that are needed to relieve pain and swelling and prevent future problems.

When these kinds of treatments alone do not relieve your varicose veins, you may require a surgical or minimally invasive treatment, depending upon the extent and severity of the varicose veins. These treatments include radiofrequency and laser ablation, ambulatory microphlebectomy, sclerotherapy, and surface laser treatment.

Sclerotherapy

During sclerotherapy, Dr. Robbins injects a chemical into your varicose veins. The chemical irritates and scars your veins from the inside out so your abnormal veins can then no longer fill with blood. Blood that would normally return to the heart through these veins returns to the heart through other veins. Your body will eventually absorb the veins that received the injection.

Radiofrequency Ablation

Ablation uses a thin, flexible tube called a catheter inserted into a varicose vein. Tiny electrodes at the tip of the catheter heat the walls of your varicose vein and destroy the vein tissue. As with chemical sclerotherapy, your varicose vein is then no longer able to carry blood, and it is eventually absorbed by your body.

Laser Ablation

Laser treatment is another way to treat varicose veins. Your physician inserts a tiny fiber into a varicose vein through a catheter. The fiber sends out laser energy that kills the diseased portion of your varicose vein. The vein closes and your body eventually absorbs it.

Ambulatory Microphlebectomy

Ambulatory microphlebectomy is a moderately non-invasive method to remove surface varicose veins. This procedure is done in Dr. Robbins office using tumescent local anesthesia and is typically done in conjunction with ELA or RFA for treatment of the primary problematic source vein. Multiple nicks in the skin above the surface of the varicose vein allow the physician access to “hook” and effectively remove the vein. These nicks heal with minimal cosmetic evidence and produce immediate cosmetic results. Pain is mild, and a mild sedative can be prescribed for the day of the procedure. After the treatment is completed, a bandage wrap is applied to the leg and the patient is instructed to wear a compression stocking for a short period of time. There is a possibility of bruising, but compression therapy, elevation of the leg, and mild exercise lessen this side effect.

What results can be expected?

With the evaluation and treatment methods available today, spider and varicose veins can be treated at a level of effectiveness and patient safety previously unattainable, although, a 100% resolution of all visual veins is considered unrealistic by medical experts. Regardless of which treatment method is used, success largely depends on careful assessment of the problem by a knowledgeable and trained physician, a comprehensive treatment plan, and ultimately the compliance of the patient. There are many underlying causes of varicose and spider veins, therefore, successful treatment of a particular vein problem does not necessarily prevent the occurrence of new venous concerns. An open relationship with your vein specialist where you can communicate your results and concerns of your vein issues, is key in the long-term success of your venous treatments.
