[Variants in the definitive organization of the lumbar lymph-conducting pathways in the applied aspect]

Topographic-anatomical investigations gave grounds for the description of 4 stages of the development of the posterior parietal bed of the abdominal cavity. On the basis of the embryo-anatomical systematization three morpho-topographic types of the lumbo-lymphatic pathways were established: right-sided (20%), left-sided (20%) and uniform (60%) types, each of them playing a certain part in metastasizing. Embryo-anatomical grounds are given for operative accesses to the superficial group of the right and left lumbar lymphatic pathways.
