Postcaval DetailsSystemLymphatic systemAnatomical terminology[edit on Wikidata] The periaortic lymph nodes (also known as lumbar) are a group of lymph nodes that lie in front of the lumbar vertebrae near the aorta. These lymph nodes receive drainage from the gastrointestinal tract and the abdominal organs. The periaortic lymph nodes are different from the paraaortic lymph nodes. The periaortic group is the general group, that is subdivided into: preaortic, paraaortic, and retroaortic groups. The paraaortic group is synonymous with the lateral aortic group. Divisions The periaortic lymph node group is divided into three subgroups: preaortic, paraaortic, and retroaortic: The preaortic group drains the gastrointestinal viscera. They can be subdivided into three groups: the celiac nodes, the superior mesenteric nodes, and the inferior mesenteric nodes. The paraaortic group
