Ganglion Impar

The Ganglion Impar is a small structure, located in the retroperitoneal space anterior to the sacrococcygeal junction. It is the terminal part of the two sympathetic chains. Pain fibers from the perineum, distal parts of the rectum, vagina and urethra are carried with sympathetic fibers that pass through the Gangion Impar. The block can be performed on diagnostic or therapeutic basis for refractory pain management of cancer or non-cancer etiology where the pain is thought to originate from the above mentioned structures. It is a relatively easy block with potentially low rate of complications.
