Post-dural puncture headache is an increasingly recognized cause of chronic headache. Outside of clinical history and myelography that requires an additional dural puncture, there is no reliable diagnostic test to evaluate for persistent dural defects. We describe the injection of iodinated contrast into the dorsal epidural space under CT guidance in 5 patients as a potential tool to visualize persistent dural defects.
硬膜穿刺后头痛是一种日益被认识到的慢性头痛病因。除了临床病史和需要额外进行硬膜穿刺的脊髓造影外，没有可靠的诊断测试来评估持续性硬膜缺损。我们描述了在CT引导下向5例患者的背侧硬膜外间隙注射碘化造影剂，作为一种可视化持续性硬膜缺损的潜在工具。
