SUMMARY: The major splancnic nerve is part of the nervous simpathic system and is placed in the posterior mediastine heading for the abdomen to innerve the abdominal visceras, and it's anatomical knowledge is of great importance to surgical procedures on this region.
Because of the differences related to its origin and relationship with the spine, added to its importance on keeping the operation of the body, determinated the aim of this study with a detailed analysis of the major splancnic nerve was chosen, which would reduce the risks of its damage improving the surgical procedures on the superior mediastine.
The major splancnic nerve is placed on the posterior mediastine heading for the abdomen to innerve the abdominal visceras, and its anatomical knowledge is of great importance to surgical procedures on this area, such as splancnicectomy to heal the pain in chronical pancreatites (Yeo, 1999).
The only structure we consider as being important to relate with the nerve was the spine, as it is always on a maintained position in the posterior mediastine.
