53 Predicting epidural space spread using ultrasound color doppler imaging in interlaminar epidural steroid injection: a prospective observational study

Background and Aims While the use of fluoroscopy-guided transforaminal epidural steroid injection (TFESI) to help spread the injectate toward the ventral side has increased, this procedure entails a radiation risk. Recently, ultrasound has been widely applied in the medical field; among ultrasound methods, color Doppler is useful for predicting the direction of the injectate. This study describes a novel technique employing color Doppler to help predict epidural space spread in interlaminar epidural steroid injection (ILESI)
