BackgroundThe purpose of this study was to evaluate epidurography contrast patterns in fluoroscopically guided cervical interlaminar epidural injections using the midline approach.MethodsAll 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).ResultsThe 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).ConclusionsTwo milliliters of contrast solution can provide optimal dispersion of contrast in a ventral and longitudinal spread.
