Fifty consecutive patients with suspected herniated nucleus pulposus at L4-5 or L5-S1 were evaluated prospectively with both epidural venography and iophendylate myelography. The two procedures were compared with respect to diagnostic accuracy, ease of performance, and complications. Evaluation of both the L4-5 and L5-S1 disk space levels was attempted in every patient, for a total of 100 levels. Surgical confirmation was obtained for 37 levels in 30 patients. While epidural venography is useful, myelography remains the procedure of choice.
