Skin and subcutaneous tissue strain in legs with lymphedema and lipodermatosclerosis.
We compared skin and subcutaneous tissue strains in legs with lymphedema (LE) of varying severity and legs with lipodermatosclerosis (LDS) using real-time tissue elastography. Strain was assessed at the inner thigh and calf in 62 legs with LE (International Society of Lymphology [ISL] stage 0: 16, stage I: 5, stage II: 28, late stage II: 7, stage III: 6) and 15 legs with LDS. In thighs and calves with LE, skin strain and subcutaneous tissue strain did not significantly differ between ISL stage 0, that is, asymptomatic legs, and other stages. However, strain values in calves with LDS were lower than values in calves with stage 0, II and late II LE. These results indicate that skin and subcutaneous tissue strains were not lower in legs with symptomatic LE than in asymptomatic legs until an advanced stage.
