Individual and sexual characteristics of the common iliac lymph nodes in elderly persons

The common iliac lymph nodes (CILN) have been investigated on 24 preparations from corpses of elderly persons (5 male and 7 female corpses), died from the causes not connected with the lymphatic system diseases, lower extremities and pelvic organs. The CILN with their afferent and deferent lymphatic vessels are revealed by means of interstitial injection into the lower extremities and pelvic organs, as well as by means of direct injection into lymphatic vessels. The form, amount, size and topography of CILN are studied. Lymphatic vessels, running from certain parts of the body and organs to various subgroups of CILN are described, as well as lymphatic vessels, connecting the nodes both within each subgroup and between the subgroups. There is a tendency in prevalence of amount and size of the lateral subgroup of the lymph nodes over the nodes of other subgroups of CILN; tendency in prevalence of amount of the lymph nodes in men, and their size--in women; prevalence of amount of right CILN and their size in the left--in persons of both sex; in 70% of the cases the amount of afferent lymphatic vessels to CILN prevails over that of the deferent lymph nodes.
