Insights
The iliosacral lymphocenter, crucial for lymphatic drainage, typically contains 5-11 nodes. These nodes exhibit significant size and mass variability, suggesting a uniform anatomical grouping.
Area of Science:
- Anatomy
- Surgical Anatomy
Background:
- The iliosacral lymphocenter plays a role in lymphatic drainage.
- Understanding its anatomical variations is crucial for surgical procedures.
Purpose of the Study:
- To investigate the anatomical characteristics of the iliosacral lymphocenter.
- To determine the number, size, and mass of these lymph nodes.
Main Methods:
- Dissection and morphometric analysis of iliosacral lymph nodes.
- Evaluation of node number, dimensions, and mass.
Main Results:
- The iliosacral lymphocenter typically has 5-11 nodes, predominantly located along the common iliac artery.
- Node size ranged from 1.5-20 mm, with masses from 1.7-98.9 mg.
- Total lymphocenter mass varied from 131-340 mg, with slight right-sided asymmetry.
Conclusions:
- The iliosacral lymphocenter is a consistent anatomical entity.
- Considerable variability in node size and mass exists, supporting their classification as a single topical group.
Abstract:
The majority of nodes of iliosacral lymphocenter are attached to the wall of a. iliaca communis dextra et sinistra from its origin to the rise of a. circumflexa ilium profunda. The total number of nodes of the lymphocenter ranges from 5 to 11, without any marked dextro-sinistral asymmetry. The size of nodes, as expressed by their length, showed a wide range from 1.5 to 20 mm and in more than one half of nodes it was 5 to 10 mm. The mass of individual nodes ranged from 1.7 to 98.9 mg and in one half of them was up to 20 mg. The total mass of all nodes of lymphocenter fluctuated individually from 131 to 340 mg with a slight asymmetry in favour of the right-hand side. Regarding a considerable positional variability of nodes the authors do not hold a further particularization of iliosacral lymphocenter for reliable and they consider the nodes under study to be a uniform topical group.
