venography
Definition
The process of producing images of veins, typically using X-ray imaging with contrast dye to visualize the venous system
Clinical context
A 65-year-old woman presents to the emergency department with sudden onset of severe leg pain and swelling. She has a history of prolonged bed rest following hip surgery two weeks ago. A venography is ordered to evaluate for deep vein thrombosis. The contrast dye injected into her vein outlines the venous system and reveals a filling defect in the femoral vein, confirming the diagnosis of acute deep vein thrombosis.
