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.
对69例疑似腰椎间盘突出症导致神经根受压的患者进行了腰椎硬膜外静脉造影，并与脊髓造影和椎间盘造影进行了比较。当两位放射科医生将静脉造影片视为未知片进行解读时，仅有78%的结果一致。23%的静脉造影检查结果欠佳，其中大多数发生在既往接受过手术的患者中。静脉造影假阴性发生率为13%。中央型椎间盘突出比外侧型椎间盘突出更易漏诊。
