Comparison of the Use of VAC System in Transplants of Leg Ulcers Versus Usual Dressing Method

Comparison of the Use of VAC (Vacuum Assisted Closure) System in Transplants of Leg Ulcers Versus Usual Dressing Method. A Monocentric, Prospective, Randomized, Parallel Groups Study

To evaluate the VAC (Vacuum Assisted Closure) therapy in transplants of leg ulcers versus usual dressing method. The VAC Therapy system consists of:

• A unit delivering a precise under atmospheric pressure, controlled and regulated in the wound site,
• Consumables necessary for the implementation of the dressing,
• Collecting tanks exudates with gel. VAC therapy is a system using negative pressure. It is known to be efficient into care of chronic wounds and ulcerous wounds by increasing the cicatrisation.

This system is systematically used into the dermatology unit of the CHU of Saint-Etienne after transplants of leg ulcers, but no data confirms the interest of this method compared to usual dressing method. This study will provide this data.

Inclusion Criteria:

• patient hospitalized into the dermatology unit
• patient with an evolutive leg ulcer since more than 1 month
• signed informed consent

Exclusion Criteria:

• known allergy to one of dressings used in this study
• patient with a non-treated osteomyelitis
• patient with tumoral tissues into the wound
• patient with raw organ or raw blood vessels
• patient with an anticoagulation treatment with a potentially hemorrhagic curative dose
• patient having hemostasis problems that can lead to hemorrhagic exudates
