title: [Case of parturient who underwent resection of a spinal Tumor].
abstract: Spinal tumors are rare in pregnancy, but they cause a serious problem in terms of continuing pregnancy. Here, we present a parturient with severe lumbago who underwent resection of a spinal tumor. A 42-year-old parturient at 26 weeks of gestation presented with acute onset of severe pain in the lumbar region and lower extremities. Magnetic resonance imaging revealed an intraspinal tumor from L4 to L5. Although sciatic nerve block and epidural anesthesia were performed to relieve the pain, their analgesic effects were insufficient. Since the continuation of pregnancy was difficult because of the severe pain, she was scheduled for the resection of the tumor under general anesthesia at 28 weeks gestation. Fetal heart monitoring was used to evaluate abnormal heart rate patterns in the operating room. In order to avoid a decrease in uteroplacental blood flow, the intraoperative systolic blood pressure was maintained at 100 mmHg or more and end-tidal carbon dioxide was maintained at 35-40 mmHg. She was placed on left lateral position to avoid aortocaval compression, and surgery was uneventfully completed. The pain was relieved after surgery, and the parturient could continue the pregnancy. She under- went cesarean section at 40 weeks of gestation, and gave birth to a healthy baby.
