Abstract
The abdominal and pelvic sympathetic nervous system mediates visceral sensation and vasomotor tone to the abdominal organs and vessels, as well as sudomotor, vasomotor, and pilomotor function of the lower extremities. Pain sensation that is sympathetically maintained or mediated can be treated by a targeted block of the abdominal sympathetic ganglia or plexuses. A comprehensive understanding of the relevant physical anatomy and fluoroscopic or sonographic anatomy is a prerequisite for safely and effectively performing a sympathetic blockade.
