  • Title: Inferior hypogastric plexus blockade: a transsacral approach.
    Author: Schultz DM.
    Journal: Pain Physician; 2007 Nov; 10(6):757-63. PubMed ID: 17987098.
    Abstract:
    BACKGROUND: Despite recent refinements in the technique of hypogastric plexus blockade, the lower pelvic organs and genitalia are innervated by fibers from the pre-sacral inferior hypogastric plexus and these fibers are not readily blocked using paravertebral or transdiscal approaches. DESIGN: Report of a technique to introduce a transsacral approach to blockade of the inferior hypogastric plexus. METHODS: A technique for performing inferior hypogastric plexus blockade by passing a spinal needle through the sacral foramen is described with 15 blocks in 11 patients. RESULTS: Fifteen inferior hypogastric plexus blocks were performed on 11 female patients who presented with chronic pelvic pain. Pelvic pain was decreased following 11 of the procedures with pre- and post-pain scores (SD) of 7.4 (2.3) and 5.0 (2.7), respectively (P < 0.05). There were no complications or unusual occurrences. CONCLUSIONS: This block can be performed safely and effectively if the interventionalist has a high degree of familiarity with sacral anatomy, refined needle steering technique, and expertise in fluoroscopy. Properly performed, transsacral blockade of the inferior hypogastric plexus is a safe technique for the diagnosis and treatment of chronic pain conditions involving the lower pelvic viscera.
