Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
AIM:Evaluate the efficacy of the autologous PRP in the treatment of vascular ulcers, comparing to the conventional treatment ( cure with humid environment), in primary care patients with chronic venous insufficiency in C-6 degree (CEAP classification).
DESIGN: A study will be executed, which will consist in a randomized clinical test, multicentered, in parallel groups and opened. 150 patients suffering of venous vascular ulcers will be studied, who will be between the age of 40-100 years old, and who will be attached to 10 health centers. Variables for the identification, following, result and patient profile have been defined. Emphasize the variables of "ulcer area decreasing", "CIVIQ index", "% one cure per week".

Platelet-Rich Plasma
Our goal is to evaluate the efficacy of the autologous Platelet-Rich Plasma (PRP) in the treatment of vascular ulcers, comparing to the conventional treatment (cure with humid environment), in primary care patients with chronic venous ulcer.
Platelet-Rich Plasma
For obtaining autologous PRP, will be drawn from 9-30 ml of blood of the patient in sterile tubes containing 4.5 ml of 3.8% sodium citrate. The tubes will be centrifuged for 8 min at 580 Gs to separate the different blood components according to density gradient. After centrifugation, we will aspire the PRP. We will add CaCl2 to the PRP (50l per ml of liquid plasma). While the plasma will get gelified, we will cure the ulcer with saline cleaning and mechanical removal. Then the ulcer will be covered with gelified PRP and a secondary dressing. This cure will be done each 7 days.
Usual treatment
Usual treatment: Patients in the control group will be treated according to Osakidetza recommendations of humid environment cure. The choice of material for the cure depends on the prior assessment of the wound and surrounding skin, appearance and amount of exudate and the presence or absence of signs of infection. These cures will be performed every 48-72 hours.
