Definition[Bearbeiten]
The Nodi lymphatici iliaci interni are a group of lymph nodes that belong to the lymphatic system of the pelvis.
Anatomy[Bearbeiten]
The internal iliac lymph nodes are localised between the vascular branches of the internal iliac artery. A distinction is made between three groups:
- Nodi lymphatici gluteales superiores: 2-3 lymph nodes along the medial side of the superior gluteal artery
- Nodi lymphatici gluteales inferiores: several lymph nodes along the inferior gluteal artery - in women between the uterine artery, the middle rectal artery and the vaginal artery
- Nodi lymphatici sacrales (laterales): 2-3 lymph nodes lateral to the lateral sacral arteries
The lymphatic drainage takes place via the common lymphatic nodes into the lumbar trunk.
Tributary area[Bearbeiten]
The tributary area of the nodi lymphatici iliaci interni includes:
- Gluteal musculature
- Pelvic wall
- Rectum
- Parts of the ureter (ureter)
- Parts of the urethra (ureter)
- in men: prostate, seminal vesicle
- in women: uterus (cervix), vagina
Clinic[Bearbeiten]
In the surgical treatment of malignant tumours of the pelvic region, the nodi lymphatici iliaci interni can be removed as part of a pelvic lymphadenectomy.
