We report a patient with a previously undiagnosed spine metastasis that developed into paraplegia following a continuous epidural block. This is an uncommon and quite rare complication. A 52-year-old male hepatoma case with upper abdominal cancer pain was indicated for a celiac plexus block. A continuous epidural block was performed prior to the celiac plexus block. A Tuohy needle was introduced at the Tll-12 interspace and an epidural catheter was inserted about 15cm in length cephalad through the needle. During the procedure, a saline solution was infused through the Tuohy needle and epidural catheter. The tip of the catheter was expected to be near the T, level. The upper abdominal pain was subsided after the injection of 3 ml of 1% lidocaine and 3 ml of 0.5% bupivacaine via the epidural catheter around noon time. When we made ward rounds that evening, the patient complained of motor weakness and sensory change below T; however, the local anesthetics were injected continuously through the epidural catheter every 4 hours. Next morning, because the patient complained of paraplegia, the epidural injection was discontinued. Under the suspicion of spinal cord compression, a computed tomogram of the thoracic spine was taken. It showed an osteolytic destruction of the right pedicle of T, due to a metastatic tumor. This suggested subclinical tumor invasion to the epidural space. The infusion of saline and local anesthetics through the Tuohy needle and the epidural catheter may increase the epidural pressure and compress the spinal cord. A laminectomy was refused by the family and the patient was discharged from the hospital after 6 treatments of radiotherapy without any improvement. It is advisable to take a spine CT or bone acan in terminal cancer patients before an epidural block, and when paraplegia develops after an epidural block. |
