HOW ARE VARICOSE VEINS DIAGNOSED?
DIAGNOSTIC TESTS AND PROCEDURES
Your doctor may recommend a Doppler ultrasound to check blood flow in your veins and to look for blood clots. A Doppler ultrasound uses sound waves to create pictures of structures in your body.
During this test, a handheld device will be placed on your body and passed back and forth over the affected area. A computer will convert the sound waves into a picture of the blood flow in your arteries and veins.
Although rare, your doctor may order an angiogram to get a more detailed look at the blood flow through your blood vessels. For this procedure, dye is injected into your veins. The dye outlines your veins on x-ray images.
An angiogram can help your doctor confirm whether you have varicose veins or another problem.
HOW ARE VARICOSE VEINS TREATED?
Lifestyle changes often are the first treatment for varicose veins. These changes can prevent varicose veins from getting worse, reduce pain, and delay other varicose veins from forming. Lifestyle changes include the following:
- Avoid standing or sitting for long periods without taking a break. When sitting, avoid crossing your legs. Raise your legs when sitting, resting, or sleeping. When you can, raise your legs above the level of your heart.
- Do physical activities to get your legs moving and improve muscle tone. This helps blood move through your veins.
- If you’re overweight or obese, lose weight. This will improve blood flow and ease the pressure on your veins.
- Avoid wearing tight clothes, especially those that are tight around your waist, groin (upper thighs), and legs. Tight clothes can make varicose veins worse.
- Avoid wearing high heels for long periods. Lower heeled shoes can help tone your calf muscles. Toned muscles help blood move through the veins.
Your doctor may recommend compression stockings. These stockings create gentle pressure up the leg. This pressure keeps blood from pooling and decreases swelling in the legs.
There are three types of compression stockings. One type is support pantyhose. These offer the least amount of pressure. A second type is over-the-counter compression hose. These stockings give a little more pressure than support pantyhose. Over-the-counter compression hose are sold in medical supply stores and pharmacies.
Prescription-strength compression hose are the third type of compression stockings. These stockings offer the greatest amount of pressure. They also are sold in medical supply stores and pharmacies. However, you need to be fitted for them in the store by a specially trained person.
Medical procedures are done either to remove varicose veins or to close them. Removing or closing varicose veins usually doesn’t cause problems with blood flow because the blood starts moving through other veins.
You may be treated with one or more of the procedures listed below. Common side effects right after most of these procedures include bruising, swelling, skin discoloration, and slight pain.
The side effects are most severe with vein stripping and ligation (li-GA-shun). Although rare, this procedure can cause severe pain, infection, blood clots, and scarring.
Sclerotherapy (SKLER-o-ther-a-pe) uses a liquid chemical to close off a varicose vein. The chemical is injected into the vein to cause irritation and scarring inside the vein. The irritation and scarring cause the vein to close off, and it fades away.
This procedure often is used to treat smaller varicose veins and spider veins. It can be done in your doctor’s office, while you stand. You may need several treatments to completely close off a vein.
Treatments are typically done every 4 to 6 weeks. Following treatments, your legs will be wrapped in elastic bandaging to help healing and decrease swelling.
Microsclerotherapy (MI-kro-SKLER-o-ther-a-pe) is used to treat spider veins and other very small varicose veins.
A small amount of liquid chemical is injected into a vein using a very fine needle. The chemical scars the inner lining of the vein, causing it to close off.
This procedure applies light energy from a laser onto a varicose vein. The laser light makes the vein fade away.
Laser surgery is mostly used to treat smaller varicose veins. No cutting or injection of chemicals is involved.
Endovenous ablation (ab-LA-shun) therapy uses lasers or radiowaves to create heat to close off a varicose vein.
Your doctor makes a tiny cut in your skin near the varicose vein. He or she then inserts a small tube called a catheter into the vein. A device at the tip of the tube heats up the inside of the vein and closes it off.
You will be awake during this procedure, but your doctor will numb the area around the vein. You usually can go home the same day as the procedure
For endoscopic (en-do-SKOP-ik) vein surgery, your doctor will make a small cut in your skin near a varicose vein. He or she then uses a tiny camera at the end of a thin tube to move through the vein. A surgical device at the end of the camera is used to close the vein.
Endoscopic vein surgery usually is used only in severe cases when varicose veins are causing skin ulcers. After the procedure, you usually can return to your normal activities within a few weeks.
For ambulatory phlebectomy (fle-BEK-to-me), your doctor will make small cuts in your skin to remove small varicose veins. This procedure usually is done to remove the varicose veins closest to the surface of your skin. You will be awake during the procedure, but your doctor will numb the area around the vein. Usually, you can go home the same day that the procedure is done.
Vein stripping and ligation typically is done only for severe cases of varicose veins. The procedure involves tying shut and removing the veins through small cuts in your skin.
You will be given medicine to temporarily put you to sleep so you don’t feel any pain during the procedure.
Vein stripping and ligation usually is done as an outpatient procedure. The recovery time from the procedure is about 1 to 4 weeks.
