title: Unreliability of epidural venography in lumbar disc disease.
abstract: Lumbar epidural venography has been compared with myelography and discography in 69 patients suspected of having nerve root compression from herniated lumbar intervertebral discs. Only 78% agreement occurred when venograms were interpreted as unknowns by two radiologists. Twenty-three percent of the venographic examinations were suboptimal, most of these in patients operated upon previously. False-negative venography occurred in 13%. Midline disc herniations were missed more often than lateral herniations.
