Intravascular Injection Rate During Lumbar Transforaminal Epidural Block Using Bent or Straight Needles

Kyungpook National University Hospital260 enrolled

Overview

The primary aim of this study was to compare intravascular injection rates during LTFESI between commonly used straight and bent chiba needles.

Lumbar transforaminal epidural steroid injection (LTFESI) is widely used in clinical practice to effectively deliver injectate into the ventral epidural space. Complications associated with intravascular injection such as spinal cord infarction and paraplegia can occur during LTFESI. The incidence of intravascular injection during LTFESI was known as 9.9% \~ 17.7%. To improve the safety of the procedure, avoidance of intravascular injection is crucial, for which appropriate needle selection is important. Currently, the most commonly used block needles in LTFESI are straight or bent chiba needles. The primary aim of this study was to compare intravascular injection rates during LTFESI between commonly used straight and bent chiba needles.

Outcomes

Primary Outcomes

Intravascular injection

Intravascular injection is defined as contrast media spreading out through the vascular channel during injection of contrast media under real time fluoroscopy

Time frame: During procedure

Secondary Outcomes

Ventral epidural spreading

Ventral epidural spreading is defined when the contrast reached just behind the vertebral body in fluoroscopic lateral view.

Time frame: up to 24 weeks

Medial epidural spreading

Medial epidural spreading is defined as contrast filling the inner side of the pedicle medial margin

Time frame: up to 24 weeks

Procedure time

Procedure time is defined as the time from the point when the block needle passed through the skin to observation of the complete contrast flow pattern with real time fluoroscopy.

Time frame: During procedure
