Ganglion Impar Block

A ganglion of impar block is simple procedure performed at pain clinics in Tennessee which is safe and easy, used to treat pain in the pelvic, genital, anal, visceral, and perineal areas. This is an injection that can be used as a sympathetic block, meant to treat sympathetically mediated pain, neuropathic pain, or post-surgical pain.
Patients who benefit from this type of blockage are often those who present with poorly localized and vague pain in their “seat” region, something that is often burning in sensation and accompanied by a sense of urgency with defecation or urination.

The target in this procedure is the area known as the ganglion of impar, or the ganglion of Walther. This is a singular retroperitoneal structure which can be found at the sacrococcygeal junction. In this area there are four or five small sacral ganglia and the ganglion impar is the caudal segment of this chain. It is an area of particular importance for those patients who suffer from pain in the perineal structures or pelvic structures.

How is the block performed?

The block is performed by injecting a small amount of anesthetic into your ganglion of impar, which then interrupts the signals of sympathetic nervous system and pain fibers in the area, providing immediate relief to the patient.

When was this procedure first performed?

This procedure was first performed in 1990 and since then it has grown in its popularity and is now used for many treatments at the pain management clinics in Nashville including the treatment of perineal pain, the treatment of rectal pain, the treatment of scrotal pain, the treatment of pain to the “seat” region, the treatment of endometriosis, the treatment of vaginal protrusion, the treatment of failed back surgery syndrome, the treatment of chronic prostatitis, as well as the treatment ofcoccygodynia, and radiation proctitis, among many other pain related conditions.

How long does it take?

This procedure can be completed in under ten minutes at a pain clinic in Tennessee. Once your procedure is complete, a small dressing will be placed over the area and you will be transferred to a recovery area. For many patients, the relief comes in a matter of hours.

What are the benefits?

This block is a minimally invasive procedure, performed by pain management doctors in Nashville which can be used to treat pain in just a matter of minutes. The quickness with which relief is provided and the procedure complete are the two most important benefits. This procedure brings with it a great deal of pain relief, especially in malignancy. Patients who have this injection often enjoy between 50-100% pain relief.

What are the risks?

As with any procedure there are some risks involved. With this procedure, there are few complications because of how simple it is. This treatment might bring with it the risk of bleeding at the injection site, infection, or nerve root injury. Given the location of the ganglion there is potential for this block to prove ineffective even if the procedure is done correctly. If this happens, you will need to repeat the procedure using a slightly varied approach. Otherwise, the risks are quite minimal with high success rates.
