[Lower limb lymphography where there is no lymph circulatory disorder. Normal conditions and their limits (author's transl)].

Further lymphangiography for the lymphatic system dependent on the internal saphenous vein carried out on 70 patients to establish a lymphographical record of the pelvi-abdominal ganglia, simplified the counting of opacified vessels, and assessment of the development of the vascular system and the fragility of the walls and their calibre and pathway. The various aspects were assessed in relation to the anatomical situation (leg, thigh), age group and sex of the patients. Computerised analysis of the information lead to the conclusion that, even under normal conditions, there are statistical differences in the number of opacified vessels in the legs and in vascular fragility of the pre-inguinal region according to age group. The authors discuss the implications of the limits of the normal appearance of the lymphatic vessels.
