The danger of anaphylaxis, a rare but life threatening complication of general anesthesia (GA) can be summarized in two: 1. General Anesthesia masks the typical early signs of allergy which can be seen in an awake patient. 2. Anaphylaxis during GA manifests mostly as circulatory/ventilatory failures which can be interpreted as adverse effects of anesthetics or surgery and this can lead to critical delay of effective therapy. A 19-year-old female admitted for posterior spinal fusion and instrumentation (the 5th surgery in patient's life) desaturated seconds after intubation...

INTRODUCTION: Surgical management for lumbar stenosis is generally safe and provides significant improvements in pain, disability, and function. Successful lumbar decompression hinges on removing an appropriate amount of lamina and other compressive pathology in the lateral recess. Too little bony decompression can result in persistent pain and disability, while over resection of the pars and/or facets may jeopardize spinal stability. CASE REPORT: In this unique report, we present for the first time an acute iatrogenic grade 4 L5-S1 spondylolisthesis distal to a L3-5 laminectomy and circumferential instrumented fusion due to bilateral iatrogenic L5 pars fractures and its management and clinical outcomes after revision operation...
