Abstract

Selective lumbosacral radiculography and nerve root block techniques are very useful in determining the nerve root involved. We have done the lumbar root block to 61-year-old female who had suffered from low back pain radiating to right lower leg which was not relieved by epidural steroid injection two times. L5 root block was performed under the fluoroscopic C-arm guide. When the needle was in correct position, we injected contrast medium (lsovistR - 300, Schering, Germany). After we injected 1.5 cc isovist, the S root was figured but L5 root was not figured. When we reinjected 1.5 cc isovist, S1 root was enhanced and L5 root was slightly visible due to severe disc bulging and lateral spinal stenosis.
