The use of growth factors, CD34(+) cells and fibrin for the management of chronic venous ulcers.

Chronic venous ulceration represents a very common event. Current standard treatment includes local wound care with the application of compression. We report the effects of platelet-rich plasma in patients with chronic venous ulcers, which is able to stimulate fibroblasts, macrophages and mesenchymal cells and growth factors in order to achieve re-epithelialisation and neovascularisation within the microenviroment of the wound. We also documented the efficacy of this method as the sole treatment without surgical procedures.
