Fluoroscopically guided cervical interlaminar epidural injections using the midline approach: an analysis of epidurography contrast patterns.
BACKGROUND
The purpose of this study was to evaluate epidurography contrast patterns in fluoroscopically guided cervical interlaminar epidural injections using the midline approach.


METHODS
All epidural injections were performed at the C6-7 level in the prone position. Epidurography was performed using a fixed amount of iotrolan 240 mg I/mL (1, 2, 3 mL).


RESULTS
The rate of ventral epidural spread was 56.7% in Group A (1 mL), 90% in Group B (2 mL), and 93.3% in Group C (3 mL).


CONCLUSIONS
Two milliliters of contrast solution can provide optimal dispersion of contrast in a ventral and longitudinal spread.
