Description
María Ximena Guerbi and co-authors report a 2026 single-patient comparison of two dressings on different areas of one extensive chronic ulcer that had resisted standard care. One zone received a human amniotic membrane dressing, while another received a bovine collagen matrix, giving an internal control within the same wound.
After 59 days the membrane-treated zone healed so much better that clinicians extended it over the collagen area, and the whole wound closed. Tissue analysis showed quieter inflammatory signals and stronger markers of blood vessel growth and repair in the membrane zone. A single case cannot prove superiority, yet the side-by-side result supports larger trials of amniotic dressings for stubborn ulcers.
