VARICOSE VEINS
What are Varicose Veins?
Varicose veins are enlarged, twisted, painful superficial veins resulting from poorly functioning valves. Varicose veins are common, affecting mostly women. Causes include congenitally defective valves, thrombophlebitis, and pregnancy. Prolonged standing and increased pressure within the abdomen may increase susceptibility to the development of varicose veins or aggravate the condition.
Primary varicose veins occur because of congenitally defective valves, or without a known cause. Secondary varicose veins occur because of another condition, such as occurs when a pregnant woman develops varicose veins.

How are Varicose Veins Diagnosed?
The diagnosis is based primarily on the characteristic appearance
of the legs when the patient is standing or is seated with the
legs dangling. At times a physician may order a duplex ultrasound
exam of extremity to see blood flow and characterize the vessels,
and to rule out other disorders of the legs. Rarely, an angiography
of the legs may be performed to rule out other disorders.
How are Varicose Veins Treated?
Treatment is usually conservative. The patient will be asked to avoid excess standing, elevate the legs when resting or sleeping, and to wear elastic support hose.
Treatment may be requested to improve the appearance. Surgery such as vein stripping and ligation (removal of the varicose vein), or sclerotherapy of veins (injecting with a solution that causes scarring, which closes the vein) may be recommended. Vein stripping is a very extensive procedure, and it is usually reserved for patients who are experiencing a lot of pain or who have skin ulcers.
