Overview:

  • This poster highlights that many standard treatments fail to heal persistent venous leg ulcers (VLUs) in the long term.
  • The application of Continuous Topical Oxygen Therapy (cTOT) to these wounds can reduce hypoxia and pain, while enhancing healing and better use of compression.
  • In turn, these results may help reduce clinic visits, improving healthcare access for others.

Results

  • Patient 1: 79-year-old Veteran male patient. Wound duration: 39 months.
    • Hx: A-Fib, myodysplastic anemia, chronic kidney disease, GERD, BPH, restless leg syndrome, HTN.
    • 69% wound volume reduction in 21 weeks.
  • Patient 2: 76-year-old Veteran male patient. Wound duration: 3 months.
    • Hx: Tobacco use, CAD, sleep apnea, obstructive emphysema, idiopathic peripheral neuropathy, pulmonary HTN, pulmonary embolism. ABI = 1.0
    • 66.5% wound volume reduction in 21 weeks.
  • Patient 3: 77-year-old Veteran male patient. Wound duration: 50 months.
    • Hx: Parkinson’s, lymphedema, HTN, low back pain, sleep apnea, obesity, GERD, chronic PTSD, bilateral knee replacements.
    • 89.1% wound reduction in 20 weeks.

Conclusion:

The findings in the poster highlight cTOT as an essential complement to standard of care for non-healing VLUs.
