Objectives: Demonstrate of accidental intravascular injection during lumbar transforaminal anterior epidural steroid injection (TAESI) performed with three-dimensional imaging angiography (3DIA) and fluoroscopy.

Methods: We assessed 20 (9 males and 11 females) patients (with a total of 40 levels) whose images were received with simultaneously 3DIA and fluoroscopy-guided TAESI between January 2016 and September 2016 as retrospective.
