A Novel Modified Retrocrural Approach for Celiac Plexus Block: The Single-Needle Retroaortic Technique.

For patients with pain from upper abdominal malignancies, celiac plexus neurolysis can provide an effective means of pain control. However, there are instances when traditionally described percutaneous approaches may not be technically feasible. We describe here the successful use of a novel single-needle retroaortic approach as an alternative approach to celiac plexus neurolysis.We present 4 cases of patients with pain from upper abdominal malignancies in whom we performed celiac plexus neurolysis using a novel single-needle retroaortic approach. All 4 patients had significant pain relief and no significant adverse effects from the retroaortic approach.
