Understanding the anatomy of pelvic fascia: implications for regional anesthesia

Le résumé fourni par la source

The fascia, a continuous structure around the whole body across various anatomical locations, remains underexplored in regional anesthesia. The pelvic fascia is a particularly controversial and complicated anatomical structure. It holds significant relevance not only for surgeons but also in the realms of regional anesthesia and pain management. Many regional nerve blocking techniques in the pelvis are closely related to fascial anatomy, such as fascia iliaca compartment block, circum-psoas block, inferior hypogastric plexus block, and ganglion impar block. The continuity of fascia and interfascial spaces profoundly influences both the efficacy of blockades and the incidence of complications. A thorough understanding of pelvic fascia anatomy is crucial for understanding the potential pathways and barriers for spread of local anesthetics, enhancing analgesia, and minimizing side effects. Currently, a systematic discussion of pelvic fascia from the perspective of regional anesthesia and pain therapy is notably absent. This narrative review aims to consolidate knowledge on the anatomy of pelvic fascia pertinent to regional anesthesia and pain management, detailing relevant pelvic nerves, and associated peripheral nerve blocking techniques.
