Manejo de heridas traumáticas de difícil cicatrización con colgajos microvasculares.
Present different flap alternatives when performing microvascular free-flap reconstruction in acute hard-to-heal wounds.A retrospective review of patients whose acute hard-to-heal wounds were treated with microvascular free-flap reconstruction. Data on demographics, wound aetiology, diagnostic, previous treatment, free-flap type, free-flap size, complications and follow up were analysed.A total of 20 patients received microvascular free-flap reconstruction. The median age was 39.5 years. Twenty free-flap reconstructions were performed. These included: 3 cross-leg free flap, 1 cross-leg vascular cable bridge flap, 2 fibula osteocutaneous flap, 6 anterolateral thigh (ALT) flap, 3 thoracodorsal artery perforator (TDAP) flap, 3 fasciomyocutaneous flap, and 2 femoral artery fasciocutaneous flap. A patient required microvascular anastomosis due to hematoma; the rest did not present complications during their postoperative. Previous treatment included negative pressure wound therapy (12 patients) and surgical debridement with silver hydrogel dressings (8 patients).Hard-to-heal wounds can be unresponsive to traditional wound healing practices or local flaps. They often require free-flap reconstruction, using tissues similar to those compromised. Microvascular techniques can be an effective alternative.
