A 23-year-old primigravid patient who received epidural analgesia for pain of labour presented with persistent, apparently irremediable, unilateral analgesia. Computerized axial tomo-epidurography demonstrated absence of circumferential spread due to lateral placement of the catheter. Transforaminal escape of contrast medium into the paravertebral area had occurred and anterior and posterior midline partitioning of the epidural space was obvious. All the usual measures to promote contralateral analgesia, except re-insertion of the catheter, had been tried without success.
一名23岁的初产妇在分娩时接受硬膜外镇痛后出现持续性、明显无法缓解的单侧镇痛。计算机轴向断层硬膜外造影显示，由于导管侧向放置，造影剂未出现环形扩散。造影剂经椎间孔漏入椎旁区域，硬膜外间隙的前后中线分隔明显。除重新插入导管外，所有促进对侧镇痛的常规措施均已尝试但未成功。
