venography
Pronunciation: vee-NOG-rah-fee
Radiographic imaging of the venous system using contrast material to evaluate venous anatomy and pathology.
Full Definition
Venography is a diagnostic imaging technique that uses contrast dye and X-ray fluoroscopy to visualize the venous system. This procedure is essential in vascular surgery for evaluating deep vein thrombosis, venous obstruction, venous insufficiency, and planning venous interventions. The contrast material is typically injected directly into a peripheral vein, allowing detailed visualization of venous anatomy, flow patterns, and any abnormalities such as stenoses, occlusions, or collateral circulation.
Usage
Usage note: May be modified with anatomic descriptors (e.g., 'renal venography', 'cerebral venography').
