RESUMEN

OBJECTIVE: In critical limb ischaemia (CLI), first-line therapy is revascularisation, but alternative treatment options are needed in certain cases. Maggot debridement therapy (MDT) is historically considered to be contraindicated in ischaemic ulcers. Wound care in patients with CLI is becoming increasingly diverse with the development of novel revascularisation strategies; therefore, CLI now needs to be reconsidered as an indication for MDT. METHOD: We retrospectively reviewed five legs with CLI (five male, one female) treated with MDT between January 2013 and December 2017. Changes in skin perfusion pressure (SPP) around the ulcer before and after MDT were evaluated. One or two cycles of MDT were performed (eight in total). We also evaluated the proportion of necrotic tissue in the ulcer and the presence of exposed necrotic bone. The proportion of necrotic tissue in the ulcer was classified as NT 1+ (<25%), NT 2+ (25-50%), NT 3+ (50-75%) or NT 4+ (>75%). RESULTS: When the proportion of necrotic tissue was >50%, with no exposed necrotic bone in the wound, an increase in SPP was observed after five (62.5%) of eight cycles of MDT. And with a proportion of necrotic tissue of <25% and/or exposed necrotic bone in the wound, a decrease in SPP was observed after three (37.5%) of eight cycles. Wound healing was accelerated in the presence of increased SPP. CONCLUSION: Effective MDT with increased SPP requires an ulcerative state of necrotic tissue grade > NT 3+, with no exposed necrotic bone.
