primarily performed to diagnose deep vein thrombosis--a condition in which clots form in the veins of the leg.
also called venography, ascending contrast phlebography, or contrast phlebography
Impedance phlebography is painless and safe. It presents no risk to the patient.
Impedance phlebography is a noninvasive test that uses electrical monitoring to measure blood flow in veins of the leg.
Normal phlebography results show proper blood flow through the leg veins.
Venography (also called phlebography, ascending contrast phlebography, or contrast venography) is an invasive diagnostic test
75820-75880
is an invasive diagnostic test that provides a constant image of leg veins on a fluoroscope screen. Phlebography identifies the location and extent of blood clots.
it is painful, expensive, time-consuming, exposes the patient to a fairly high dose of radiation, and can cause complications
Impedance phlebography may be done in order to: detect blood clots lodged in the deep veins of the leg, screen patients who are likely to have blood clots in the leg, detect the source of blood clots in the lungs.
The physician should be notified if there is swelling, redness, pain, or fever.
There are several names for venous radiography (aka X-ray, radiographs and roentgenograms). These include: Venogram, venography, phlebogram, phlebography, angiogram, and angiography.
It is nearly 100% sensitive and specific in making this diagnosis.
