RT Journal Article SR Electronic T1 Intrathecal Injection of Contrast Medium to Prevent Polymethylmethacrylate Leakage during Percutaneous Vertebroplasty JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1001 OP 1002 VO 24 IS 5 A1 Sarzier, John S. A1 Evans, Avery J. YR 2003 UL http://www.ajnr.org/content/24/5/1001.abstract AB Summary: The major technical drawback of percutaneous vertebroplasty is the potential for neural compromise from leakage of polymethylmethaorylate into epidural or perivertebral veins. We have combined the procedure of intrathecal injection of contrast medium with vertebroplasty to better delineate spinal canal encroachment during injection when the posterior vertebral wall is compromised by myeloma.
