Are C1-2 punctures for routine cervical myelography below the standard of care?
OBJECTIVE
Recently, the performance of C1-2 punctures for cervical myelography was challenged in a medicolegal proceeding as being below the standard of care. We sought to examine current neuroradiologic practices and opinions on the technique.


METHODS
An 11-question survey was sent to 120 program directors of neuroradiology via e-mail links regarding cervical myelography using a C1-2 puncture. Reminders were sent during a 2-month period before data were finalized.


RESULTS
Eighty-five of 120 (71%) surveys were returned. In the previous year, 14.3% (12/85) of institutions had not performed a C1-2 puncture. Thirty-eight percent (32/85) had performed >or=6 in the same period. Seventy-nine percent (54/68 responding) favored a lumbar approach to cervical myelography, with 6% (4/68) having a predilection for a C1-2 puncture. Ninety-five percent (76/80 responding) thought that performing a C1-2 puncture for cervical myelography reflected the standard of care. Every institution except 1 had staff with expertise to perform C1-2 punctures, and 73% of the institutions teach their fellows the procedure. Ninety-three percent (78/84) of programs would perform a C1-2 puncture for thoracolumbar pathology if MR imaging was contraindicated and there was a contraindication such as a local wound infection precluding a lumbar puncture. Indications for a C1-2 approach included severe lumbar spinal stenosis, infection in the lumbar region, upper limit of the block to be delineated, technical issues preventing lumbar puncture, and the best assessment of the cervical region for myelographic films.


CONCLUSIONS
C1-2 puncture for cervical myelography, though currently not the most frequently performed method at most institutions, continues to be practiced and is considered within the standard of care by most neuroradiology programs across the country.
