Epidural block is a well-established anesthetic method and continuous epidural catheterization is a popular and effective procedure for postoperative analgesia. However, continuous epidural catheterization has associated with complications such as venous puncture, dural puncture, subarachnoid cannulation, suboptimal catheter placement and paresthesia because the tip of the epidural catheter touches the nerves of the dura in the epidural space. We would describe that epidural catheter accidentally passed out of epidural space through an intervertebral foramen. A 82-years old woman was scheduled for radical mastectomy under epidural anesthesia. The epidural catheter was placed in standard fashion without difficulty but unilateral epidural block occured on the contralateral side of surgery. Operation was taken under general anesthesia. At the end of the operation, epidurography showed that the catheter passed out of epidural space through an intervertebral foramen and contrast media spreaded over the paravertebral space(T3-T8) with right T4 nerve root area.
