Abstract
Ischemia-reperfusion injury is a rare but serious complication encountered after spinal decompression surgery. This is only the 11th case reported in the literature. There is no current mainstay of treatment; however, several therapies have been studied. This case presents a patient with myelomalacia who underwent posterior laminectomy and developed diffuse cord edema with postoperative quadriplegia. Ischemia-reperfusion injury is believed to be mediated by oxidative and nitrosative stress leading to protein degradation and lipid peroxidation. It is characterized by myelomalacia in a chronically ischemic spinal cord and hyperintensity on T2-weighted MRI after decompression. Treatment has involved steroids and rehabilitation, and outcomes have ranged from minor improvement to full recovery. Novel treatment options have shown promise in animal models.
