Lipedema of the legs is a symmetrical thickening of upper and lower leg and topically accentuated fat pads. The back of the foot is usually free of swelling. Pathogenetically it is a disturbance of the distribution pattern of subcutaneous fat tissue. Epidemiologically, the subjects affected are women, starting from puberty. Weight reduction programs do not influence the real deformations. If this abnormal fat tissue is infiltrated by angiological diseases, these manifest themselves in modified form. In particular, all the symptoms are more painful. In arterial ischemic syndromes that taut skin is susceptible to necrosis at atypical locations. For reconstruction of trunk arteries it is advisable to bypass larger bulges for better wound nealing. Venous strips should be peeled out away from fat pads and venous-bridges very carefully to protect the tissue. Acute and chronic phlebothrombosis lead to unusual and asymmetrical forms of swelling. The venous ulcer lies directly beneath a fat-muff in the gaiter region. Since they are hard to compress, free skin transplants should be considered early in the course of development. Surgery of varicose veins calls for most careful technique to ensure wound healing. From the lymphological viewpoint there are clinically and lymphographically mixed forms of lymphedema with lipedema.
