Clinical diagnostics of venous leg ulcers set the course for efficient therapy. Precise clinical findings with an objectification of signs and symptoms of chronic venous insufficiency are essential. Duplex ultrasound investigations of the leg veins are necessary in the very early stages after the appearance of leg ulcers. Furthermore, not only a clinical investigation of the arterial perfusion but also the determination of the ankle-brachial-index is obligatory. Microbiological diagnostics are currently seen as useful in Germany, due to discussions on MRSA, even though they don´t have an immediate therapeutic consequence without the presence of clinical signs of infection. Therapeutic achievements can be objectified by a continuous documentation of the wound size, the wound bed, the wound exudate and signs of infection as well as the life quality of patients with chronic wounds.
