RESUMO
A 72-year-old woman was diagnosed with Kümmell's disease of the T12 and L3 vertebrae. During bone cement injection under continuous fluoroscopic guidance, bone cement spread beyond the posterior border of the T12 vertebral body. We halted the injection immediately. A few minutes later, the patient complained of increasing right lower quadrant abdominal pain. This was diagnosed as a preceding sign of neurological complication due to thermal injury. Consequently, we administered an epidural steroid injection, followed by cooled normal saline irrigation through an epidural catheter to minimize and treat the thermal injury. The pain gradually decreased after saline irrigation and completely disappeared after approximately 10 minutes. After completing the percutaneous vertebroplasty, the patient's lower back pain improved without neurological complications. In conclusion, immediate epidural steroid injection followed by cooled normal saline irrigation through epidural catheterization can be used to treat thermal injury due to bone cement leakage.
