Table 1.
Descriptive statistics for the LSNs joining the infrarenal aortic plexus and superior hypogastric plexus. Nerves grouped inferiorly‐superiorly (1–4) and compared relative to the total infrarenal space (100%). Reported are the total number of splanchnic nerves identified and at which level. LSN, lumbar splanchnic nerve.
