Digital subtraction angiography for leg venography.
Venography was performed in 25 legs of 17 patients using digital subtraction angiography (DSA). Reliable diagnoses of deep vein thrombosis or patency were made in the majority of these cases. There were no complications. Multiple injections of contrast material were required to image the entire leg; however, the total quantity of iodine necessary for each leg averaged 9 g, significantly less than with conventional techniques. The preferred method consisted of injecting 15 ml of 100 mg iodine/ml contrast material followed by 15 ml of heparinized saline. DSA proved a safe and useful means of evaluating veins of the leg.
