Brief summary
INTRODUCTION: Vascular ulcers are an important pathology in the daily medical practice in all the assistance levels, and they have big repercussion referring to individual, social and labour levels, supposing a big consumption of human and material resources.The cure with autologous platelet rich plasma (autologous PRP) has demonstrated in different studies a decrease in the cicatrization time comparing to conventional methods in hospital levels, which becomes interesting contrasting its efficacy in primary care. AIM:Evaluate the practicability, security and potential 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 pilot study will be executed, which will consist in a randomized clinical test, multicentred, in parallel groups and opened. 40 patients suffering of venous vascular ulcers will be studied, who will be between the age of 40-80 years old, and who will be attached to five 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 .
Interventions
DRUGPlatelet Rich Plasma
DEVICEOsakidetza protocol
Patients in the control group will be treated following the recommendations of the Ezkerraldea-Enkarterri Health Region, that is, using a moist healing environment (as described in Uso racional de los productos de cura en ambiente húmedo. Plan de formación continuada de Osakidetza, 2011). The type of material used to treat and dress the wound will be chosen after the assessment of the wound and surrounding skin, type and quantity of exudate and whether there are signs of infection. Wound care will be carried out every 48-72 hours, as is the current usual practice.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of ULCER AREA | Change from baseline at 9 weeks | Change from baseline at 9 weeks of the surface area of the ulcer, in cm3, measured using ImageJ software from the weekly the photographs of the wound |
| Change of the percentage OF PATIENTS WITH A ONLY ONE TREATMENT FOR WEEK | Change from baseline at 9 weeks | Change of the percentage OF PATIENTS WITH A ONLY ONE TREATMENT FOR WEEK |
| REDUCTION IN ULCER SIZE | Change from baseline at 9 weeks | Difference in the area of the wound between week 9 and the first treatment session. |
| Change of the CIVIQ SCORE | Change from baseline to 9th week | change of the scale assessing quality of life of patients with chronic venous insufficiency, considering four dimensions (physical, psychological, social and pain) with a score ranging from 20 to 100, where 20 corresponds to the poorest quality of life and 100 to the best. |
