title: Multiple constrast injections in epidural venography.
abstract: Multiple contrast injections were necessary in 65% of the 140 epidural venograms performed at the Penobscot Bay Medical Center between January and December 1977. Several examples of the value of multiple injections are illustrated. Institutions interested in performing epidural venography or those performing the examination on a limited basis should be aware of the need for multiple injections, allowing time for reviewing the initial series of radiographs, for reloading the film changer and injector, and for repeating fluoroscopy and catheter manipulation.
