title: Thoracic paraplegia due to missed thoracic compressive lesions after lumbar spinal decompression surgery. Report of three cases.
abstract: The authors discuss the cases of three patients in whom thoracic paraplegia developed after lumbar spinal decompressive surgery for slight lumbar spinal canal stenosis. Careful computerized tomography myelography and magnetic resonance imaging examination of the thoracic spine revealed another compressive lesion (spinal cord tumor, disc herniation, osteophyte of vertebral body, and ossification of the ligamentum flavum). Additional thoracic decompressive surgery provided partial amelioration of each patient's neurological condition. The authors suggest that to avoid such a complication physical and radiographic examination of the thoracic spine should be performed preoperatively if the lumbar imaging is inconclusive.
