Chronic pelvic pain is a common problem with variable etiology. The sympathetic nervous system plays an important role in the transmission of visceral pain regardless of its etiology. Sympathetic nerve block is effective and safe for treatment of pelvic visceral pain. One of them, the inferior hypogastric plexus, is not easily assessable to blockade by local anesthetics and neurolytic agents. Inferior hypogastric plexus block is not commonly used in chronic pelvic pain patients due to pre-sacral location. Therefore, inferior hypogastric plexus is not readily blocked using paravertebral or transdiscal approaches. There is only one report of inferior hypogastric plexus block via transsacral approach. This approach has several disadvantages. In this case a favorable outcome was obtained by using coccygeal transverse approach of inferior hypogastric plexus. Thus, we report a patient who was successfully given inferior hypogastric plexus block via coccygeal transverse approach to treat chronic pelvic pain conditions involving the lower pelvic viscera.
