[Lymphangion in health and in lymphedema].

Comparative analysis of lymphangion construction in different organs and sites of human body is performed. Quantitative parameters of lymphangions (length, width, volume) are found to have age and site peculiarities. Myo-myocyte contacts of the nexus type and fascicular-reticular organizational principle of the cells underly myocyte association into functional syncytium. The valve consists of a muscleless fold and valvular bolster containing muscles. Restructuring of lymphangions in lower limb lymphedema are observed. In the course of the disease progression myocyte atrophy occurs which is followed by lymphangion wall collagenization. The alterations in lower limb lymphangions are proportional to the gravity of the disease.
