Varicose Veins : Diagnosis

How are Varicose Veins Diagnosed?

The diagnosis of varicose veins is made primarily by physical examination. The accuracy of physical examination is further improved with the aid of a hand-held Doppler instrument, which allows the examiner to listen to the blood flow. The most accurate and detailed test is a duplex ultrasound exam, which provides an ultrasound image of the vein to detect any blockage caused by blood clots, and to determine whether the vein valves are working properly. Measurement of the venous function of the leg may be obtained with other tests such as plethysmography. These diagnostic tests are painless.
