Arms Assigned Interventions
No Intervention: A - Standard of Care (control)
Standard of care - dressings and sustained compression only
Experimental: B Same treatment for 6 weeks
200ppm NO gas 8hrs/day 6 weeks NO gas in nitrogen is delivered constantly to a patch over the wound
Drug: Nitric Oxide - same dose 6 wks
200ppm, 8hrs / day for 6 weeks NO gas in nitrogen delivered to a patch over the wound
Experimental: C - modified treatment, 5 wks lower dose
200 ppm No gas 8 hrs/day 1 wk, 20ppm 8hrs/day 5 weeks Gas is NO in nitrogen delivered constantly for 8 hours to a patch over the wound
Drug: Nitric Oxide modified treatment
200ppm, 8hrs/day for 1 week, followed by 25ppm 8hrs/day for 5 weeks Gas is delivered to a patch over the wound

Detailed Description:
Prospective, single center. Controlled study of a moisture retentive wound dressing and sustained compression with 6 weeks of 8 hour daily nitric oxide treatments.
