Chapter 10 Venous system

Peripheral Venography

Intravenous (i.v.) peripheral venography is an invasive procedure requiring i.v. injection of contrast medium and the use of ionizing radiation. Marked limb swelling can result in failure to cannulate a vein which precludes use of the technique. False-negative results do occur. It is still considered the gold standard for diagnosis of deep venous thrombosis, but is now only rarely performed.
