Pleural effusion after CT-guided alcohol celiac plexus block.

The accuracy and safety of an alcohol celiac plexus block have been substantially increased by the use of the computerized tomography (CT)-guided technique (1) because most of the complications and failures of a celiac plexus block with conventional radiologic control are closely related to the inappropriate placement of the needles (2,3). We have seen, however, two cases of pleural effusions after celiac plexus blocks with alcohol under CT guidance technique.
