Left iliac artery injury during anterior lumbar spine surgery diagnosed by intraoperative neurophysiological monitoring

Serious vascular injury is a rare, but potentially devastating complication during anterior lumbar spinal surgery. The authors describe the first reported case where vascular injury was detected by multimodality neurophysiological monitoring during an L3–S1 anterior lumbar interbody fusion. The case demonstrates the need for multi-modality monitoring and the combined use of somatosensory-evoked potentials and motor-evoked potentials
