Case report and literature review. ⋯ Right-to-left atrial shunts may predispose to cerebral emboli during scoliosis surgery. These emboli may be a cause of postoperative visual field defects.
-
A report of five cases of thoracolumbar osteoid osteoma treated with combined computer-assisted and gamma probe-guided high-speed drill excision. ⋯ The combination of both computer-assisted surgery and gamma probe-guided high-speed drill excision for osteoid osteoma of the spine helps to localize and excise the nidus of the osteoid osteoma with minimal bone resection of the posterior spinal structures.

Light microscopy study of the lumbar spinal meninges of a murine model of Marfan syndrome. ⋯ These morphologic findings in the Marfan phenotype mouse mimic the findings of disordered elastic-fibers in other Marfan tissues and demonstrate gross attenuation of the tissue architecture, corroborating the theory that dural ectasia in Marfan syndrome results from hydrostatic pressure on weakened dura. These changes may be due in part to transforming growth factor beta overactivation and gelatinase-A-mediated elastolysis and collagen breakdown.
