Case report: successful treatment of the lumbar plexus block for lumbar spinal canal stenosis accompanying the diffi culties of radiation therapy

Abstract

The patient was a 77-year-old male. His lumbosacral pain was so severe that the scheduled radiation therapy for lung cancer was postponed because of the difficulties in keeping a supine position. Pregabaline (75 mg/day) and combination tablets of tramadol hydrochloride (75 mg/day) and acetaminophen (650 mg/day) were prescribed, but his pain was not relieved. He was referred to our clinic. On the basis of his symptoms and MRI findings, his pain was assumed to in the left 3rd lumbar radiculopathy of lumbar spinal canal stenosis. We started oral administration of steroid followed by lumbar plexus block, which relieved his pain and the difficulty of keeping supine position, and then the scheduled radiation therapy was completed.
