[Percutaneous neurolysis of the celiac plexus. Description of a new CT-guided technique and preliminary results].

June 1991 to June 1992, twelve CT-guided percutaneous celiac plexus neurolyses were performed by a new simplified technique with the patient in left-hand side decubitus and a single right lumbar needle access. CT guidance allows the interventional radiologist to locate the best access point on the skin, to give the needle the appropriate depth and inclination to avoid passing through pleura, parenchyma and vessels, and finally to check the correct position of the needle tip and the spread of neurolytic solution. In left-hand side decubitus, fat and loose connective tissue around ganglia and vessels expands much more, thus allowing the alcohol-contrast medium solution to spread easily and evenly getting to both celiac ganglia by gravity. The analgesic value of celiac plexus neurolysis has been proved complete and lasting. The technique is quick and safe (apart from inevitable hypotension due to splanchnic vasodilatation).
