How is Chronic Venous Insufficiency Diagnosed?
The diagnosis of CVI is made primarily by physical examination. The accuracy of physical examination can be further improved with the aid of an instrument called a hand-held Doppler instrument. This allows the examiner to listen to the blood flow. The most accurate and detailed test, however is a venous duplex ultrasound exam. This provides an ultrasound image or picture of the vein so that any blockage caused by blood clots or improper vein value function can be detected. A CAT scan or MRI may be used to exclude other causes of leg swelling. These diagnostic tests are painless.
