Definition[Bearbeiten]
The Nodi lymphatici lumbales are a group of lymph nodes in the lumbar region that are localised in the retroperitoneal space on the abdominal aorta.
Anatomy[Bearbeiten]
The nodi lymphatici can be divided topographically into three groups:
- Nodi lymphatici lumbales dextri (right group), with
- Nll. cavales laterales (lateral to the vena cava)
- Nll. praecavales (in front of the vena cava)
- Nll. postcavales (behind the vena cava)
- Nodi lymphatici lumbales intermedii (middle group), between aorta and vena cava
- Nodi lymphatici lumbales sinistri (left group), with
- Nll. aortici laterales (lateral to the aorta)
- Nll. praeaortici (in front of the aorta)
- Nll. postaortici (behind the aorta)
The following organs belong to the tributary area of the lumbar lymphatic nodes:
- Kidneys
- Adrenal glands
- ureters
- Testicles or ovary
- Fallopian tubes or vas deferens
- Uterus (fundus region and parts of the corpus)
- Parts of the body wall
The lymph drains from the lumbar lymph nodes into the lumbar trunks, sometimes also directly into the cisterna chyli.
Clinic[Bearbeiten]
In malignant tumours in the area of the above organs, lymph node metastases can settle in the lumbar lymph nodes.
