[The inguinal paravascular technique of lumbar plexus block--anatomical pretests were unsuccessful].
Using 28 anatomic preparations, the boundaries of dye expansion in tissues adjacent to nervous stems have been experimentally studied during the application of lumbar plexus local anesthesia technique via inguinal paravascular approach according to A. Winnie. ⋯ Compact structure of perineural spaces in musculus psoas major prevents lumbar plexus infiltration. The junction of lumbar and obturator fascia, forming the fascial node between large and small pelvis, excludes any possible contacts between the dye solution and the obturator nerve.
