Spinal epidural injection CT interlaminar.
Case Discussion
The technique in this procedure was:
- obtain a localizing scan with some way of demarcating the skin (in this case, a radiopaque 'grid')
- choose a location that gives as vertical as possible route to the epidural space
- local anesthetic along proximal track (optional)
- advance needle until slight resistance (often gritty) is felt (ligamentum flavum)
- check location
- attach empty syringe with 3-4 ml of room air and keep plunger pulled while advancing remaining distance
- epidural space has low / negative pressure and air is easily injected
- confirm the extrathecal location
- inject steroid and local anesthetic
