phlebography
Contrast imaging of the venous system to evaluate venous anatomy and detect thrombosis or other venous pathology.
Full Definition
Phlebography, also known as venography, is a radiographic procedure that uses contrast material to visualize the venous system. This technique is particularly valuable in diagnosing deep vein thrombosis, venous insufficiency, and anatomical venous variants. The procedure involves catheter placement in a peripheral vein followed by contrast injection, allowing detailed visualization of venous flow patterns and potential obstructions. It can be performed on various venous systems including peripheral, pulmonary, and cerebral veins.
Usage
Usage note: Increasingly replaced by non-invasive imaging modalities but remains the gold standard for certain venous assessments.
