Whether a history of headache or "early" versus "late" ambulation (no bed rest or bed rest for 24 h) influence the occurrence of headache after lumbar iohexol myelography was studied by blinded interviews in 158 consecutive patients referred for elective lumbar myelography (LM) because of suspected lumbar disc prolapse or spinal stenosis. Headache after LM occurred more often in patients with a history of headache (57%) than in patients without such a history (29%), P < 0.001. Patients with normal myelographic findings complained of headache after LM more often (55%) than patients with abnormal myelograms (31%), P < 0.008. No difference in the incidence of headache after LM was demonstrated in early versus late ambulation.
通过对158例因疑似腰椎间盘突出症或椎管狭窄而接受选择性腰椎碘海醇脊髓造影（LM）的连续患者进行盲法访谈，研究了头痛史或“早期”与“晚期”下床活动（不卧床休息或卧床休息24小时）是否会影响腰椎碘海醇脊髓造影后头痛的发生情况。有头痛史的患者脊髓造影后发生头痛的比例（57%）高于无头痛史的患者（29%），P<0.001。脊髓造影结果正常的患者脊髓造影后头痛的主诉更为常见（55%），高于脊髓造影异常的患者（31%），P<0.008。早期与晚期下床活动在脊髓造影后头痛发生率上未显示出差异。
