Visceral nerve interventions in interventional radiology.

Chronic abdominal visceral pain management often requires multidisciplinary collaboration. Image-guided visceral nerve interventions may be critical in the management of visceral pain refractory to medical treatments. Abdominal and pelvic pain is mediated by specific nerves involving specific ganglia. The well-defined location of these ganglia provides important targets for percutaneous image-guided interventions to alleviate chronic abdominal or pelvic pain. In this review, we provide an in-depth discussion of the anatomy, indications, evidence, and technical and clinical considerations and complications for celiac plexus, superior hypogastric, inferior hypogastric, and ganglion impar block and neurolysis.
