We discuss a unique case of perforation of the dura mater, but not of the arachnoidea, by an epidural catheter. The injected test dose of the local anesthetic agent caused a partial subdural and a partial epidural hypalgesia. The exact position of the catheter and the distribution of the local anesthetic agent was confirmed by radiographic contrast material.
我们讨论了一例硬膜外导管穿破硬脑膜但未穿破蛛网膜的独特病例。局部麻醉药的注射试验剂量导致了部分硬膜下和部分硬膜外感觉减退。通过放射造影剂确定了导管的确切位置以及局部麻醉药的分布情况。
