Objective:
To determine the efficacy of negative pressure wound therapy (NPWT), when used in combination with compression bandaging, for healing chronic resistant venous ulcers.
Method:
In this pilot study, seven patients (with a total of 12 chronic resistant venous ulcers) received adjunctive NPWT and compression bandaging for 4 weeks. Their wounds were monitored for a total of 12 weeks.
Results:
Dormant ulcers were seen to rapidly develop into healthy wounds, with a granulating base.
Conclusion:
This regimen may have a role in stimulating chronic venous ulcers into healing wounds, or in preparing them for skin grafting.
