Varicose Veins
BY DR. ERIC S. HAGER
Large bulging veins in the legs that can cause many different types of symptoms.
Varicose veins can occur in almost anyone and affect up to 35% of people in the United States. You may inherit a
tendency to develop varicose veins from a parent. Women, women who have had multiple children, and obese persons
are at a higher risk.

Symptoms
MAY BE ABSENT
You may have no symptoms.
dangerous because they can travel to the heart or lung and require prompt treatment with blood thinners.
PAIN & DISCOMFORT
Pain, itching, swelling, burning, leg heaviness or tiredness, skin discoloration. Symptoms typically worsen throughout
the day and are partially relieved by elevation or wearing compression socks or stockings.
Sometimes, varicose veins clot and become painful, hot, hard and discolored. This is called phlebitis, an uncomfortable but temporary condition that will get better on its own in 2-3 months. Clots associated with phlebitis are limited to surface veins, and not dangerous – unlike clots in the deep veins (deep vein thrombosis or DVT ) that are dangerous because they can travel to the heart or lung and require prompt treatment with blood thinners.
BLEEDING
A shower or minor trauma can cause a varicose vein to burst and bleed.
SKIN TEARS
Skin tears or ulceration indicate a very severe case.
Causes
Among other things, veins are responsible for bringing blood back to the heart, sometimes working against gravity. When you walk, muscles in your leg squeeze the veins and help blood flow back into the heart. In normal veins, a series of valves assist this process. With varicose veins and with a related condition called chronic venous insufficiency, poorly functioning valves allow the blood to pool in the lower leg and cause symptoms.
Diagnosis
SEE A VASCULAR SURGEON
You will be asked questions about symptoms and medical history, including questions about family members. The
vascular surgeon will also perform a physical exam that includes gently probing for problem areas on your legs while
you are standing.
AN ULTRASOUND MAY BE RECOMMENDED
A painless ultrasound is usually given during during the same office visit to pinpoint problem veins and determine the
best way to treat them.
Treatments
Symptoms worsen throughout the day, and can usually be improved with use of compression stocking or by elevating
the feet.
COMPRESSION STOCKINGS
Knee-high compression stockings, usually that provide 20-30 mmHg of compression, will often help relieve symptoms
such as aching or swelling. These stockings compress the veins and prevent blood from traveling down pooling in the
legs. If you have insurance, most companies require that you wear compression stockings for at least three months
before covering any other type of treatment for varicose veins.
ABLATION THERAPY
If compression stockings provide insufficient relief and if the affected veins are straight enough (determined by the
ultrasound), some form of ablation therapy (laser, radiofrequency, or mechanical injection) is an option.
Treatment is administered at the vascular surgeon’s office. Your leg will be cleansed and sterile drapes placed. The vascular surgeon will then inject numbing medication and insert a catheter (thin tube) into the vein. Typically, patients feel only the injection of numbing medicine. The tube is advanced through the entire vein and then all the surrounding skin is numbed. The ablation catheter is then started and the vein treated. This part of the procedure is painless and typically takes 20 minutes. After the procedure the leg is wrapped with a compression
SCLEROTHERAPY
If the affected veins are twisted and are not sufficiently straight, sclerotherapy may be recommended. With the help of
ultrasound, a small needle is advanced through the vein to inject sclerosant, a chemical that causes the vein to spasm and clot. This type of clot is not dangerous and is broken down by your body’s natural processes so that the varicose vein disappears. Small “spider” veins can be treated in the same way, using a very small needle.
POST TREATMENT
After treatment, patients should continue to wear compression stockings to help prevent new varicose veins from
forming, and to speed recovery after varicose veins are treated.
