Les différentes techniques d’infiltration du nerf pudendal: intérêt diagnostique et/ou thérapeutique

Abstract

This is a nerve disorder, which falls within the scope of chronic pelviperineal pain, caused by direct or indirect trauma or by a canal syndrome, concerning the following nerves: the thoracolumbar nerves (obturator, ilioinguinal, ilio-hypogastric and genitocrural) and the sacral nerves (pudendal and cluneal). The aim of nerve penetration is twofold: to confirm the proposed diagnosis through an anaesthetic block and to try to provide sustainable pain management. It is mainly performed under computerised tomography (ultrasound, CT scan) guidance, to be as selective as possible about the location and thus minimise complications. An assessment before and just after penetration is critical. Penetration of the nerve plays an integral role in the management of chronic pelviperineal pain.
