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.
Normal phlebography results show proper blood flow through the leg veins.
Impedance phlebography is a noninvasive test that uses electrical monitoring to measure blood flow in veins of the leg.
Venography (also called phlebography, ascending contrast phlebography, or contrast venography) is an invasive diagnostic test
also called venography, ascending contrast phlebography, or contrast phlebography
The patient may resume normal or postoperative activities after the test.
an x ray test that provides an image of the leg veins after a contrast dye is injected into a vein in the patient's foot.
