Celiac plexus neurolysis is performed to relieve intractable upper abdominal pain. Since Kappis had performed splanchnic nerve block in 1919, many methods and its modifications of celiac plexus block have been introduced. In 1983, Ischia and in 1990, Lieberman has introduced the transaortic technique of celiac plexus block. We employed a transaortic approach with some modification of the original method in 12 patients, in which a single needle was advanced from a left posterior paramedian approach through the aorta to deposit the drug directly onto the celiac plexus. After needle has punctured anterior wall of aorta, 50% alcohol 20ml was injected and after retracting the needle to the posterior wall of aorta, also 50% alcohol 20ml was injected. 11 patients experienced marked pain relief and no major complication was encountered. The authors think that our method has some theoretical benefits in effectiveness than the original transaortic method.
