Isotope studies have related chronic headache after myelography to persistent leakage of normal cerebrospinal fluid (CSF) through an unsealed puncture hole in the dura and arachnoid. Although a technique well known to anesthesiologists, the use of an epidural blood patch (EBP) as a means to seal the dural opening is not known to many radiologists. We have used this technique successfully in three patients and believe it should be performed on all those still suffering from typical postural headaches three weeks after myelography if conservative treatment has failed and if there are no contraindications.
同位素研究表明，脊髓造影术后的慢性头痛与正常脑脊液（CSF）通过硬脑膜和蛛网膜上未封闭的穿刺孔持续渗漏有关。尽管硬膜外血贴（EBP）作为一种封闭硬脑膜开口的方法是麻醉医生熟知的技术，但许多放射科医生并不了解。我们已成功地将该技术应用于三名患者，并认为如果保守治疗失败且无禁忌证，对于脊髓造影术后三周仍患有典型体位性头痛的所有患者均应采用此技术。
