Ganglion Impar Block
Pudendal Nerve Block1

What is a Ganglion Impar Block?

A ganglion impar block is a minimally invasive procedure used to relieve chronic pain in the pelvic, perineal, and coccygeal (tailbone) areas. The ganglion impar is a small collection of nerve cells located in front of the coccyx (tailbone) that transmit pain signals from these regions. By injecting medication near the ganglion impar, pain signals can be blocked, providing significant relief.

Indications for Ganglion Impar Block

Chronic Pelvic Pain

Persistent pain in the pelvic region that has not responded to other treatments.

Coccyx (Tailbone) Pain

Pain originating from the coccyx, also known as coccydynia.

Perineal Pain

Pain in the area between the genitals and the anus.

Rectal Pain

Chronic pain in the rectal area.

Cancer-Related Pain

Pain associated with malignancies in the pelvic region.

Post-Surgical Pain

Persistent pain following surgeries in the pelvic or perineal regions.

Procedure

Frame 4

Preparation

The patient lies on their stomach, and the skin over the tailbone area is cleaned and numbed with a local anesthetic.
Frame 4

Imaging Guidance

Using fluoroscopy (a type of X-ray) or Ultrasound(USG), the physician accurately guides a needle to the area near the ganglion impar.
Frame 4

Injection

A combination of a local anesthetic and a corticosteroid or neurolytic agent is injected near the ganglion impar to block pain signals.
Frame 4

Observation

The patient is monitored for a short time after the injection to assess immediate pain relief and any adverse reactions.
