Ultrasonography measurements of skin thickness in women with and without leg edema. (A) Using ultrasonography, the distance between the skin surface and the fascia was measured as the skin thickness (between the epidermis, dermis, and subcutaneous layers). The skin thickness was 3.1 mm in a pregnant woman without edema. (B) The skin thickness was 14.4 mm in a pregnant woman with edema. 1=the skin epidermal layer; 2=the skin dermal layer; 3=the subcutaneous layer.
