— chronic non-healing wound of the first toe of the right foot, necrosis, pain; — no signs of healing after standard treatment; — endovascular intervention performed, stent placed.

Necrectomy was performed; eschar and nonviable tissue were removed, and the distal phalanx was partially resected (sequestrum). Novoskin wound dressing was applied to the prepared granulating surface. Dressing changes every 18–20 days, three procedures in total. Collagen therapy was included in the regimen; epithelialization was completed.
