Celiac plexus neurolysis (CPN) is a chemical splanchnicectomy of the celiac plexus; its goal is to ablate the efferent nerve fibres which transmit pain from the intra-abdominal viscera.
As previously emphasized, the celiac plexus is not identified as a discrete structure but is located based on its position relative to the celiactrunk.
Once the origin of the celiactrunk is located from the sub-cardiac position, the needle (whichever used) is passed through and fixed to the celiactrunk by a luer-lock.
