Outcomes of flap salvage with medicinal leech therapy

Medicinal leech therapy (MLT) to salvage venous congestion in native skin and local flaps is commonly practiced. However, the role of MLT in compromised regional and free flaps remains unclear. Leeches were used in 39 patients to treat venous congestion in native skin (n = 5), local flaps (n = 6), regional flaps (n = 14), and free flaps (n = 14). There were no total losses in patients with compromised native skin or local flaps. One patient who had received a radial forearm free flap expired before flap outcome could be assessed, and was excluded from analysis. Of the remaining 27 regional and free flaps, 33.3% were salvaged, 33.3% were partially salvaged, and 33.3% were lost. Means of 38.3 ± 34.0, 101.0 ± 11.2, and 157.9 ± 224.4 leeches and 1.7 ± 3.6, 3.2 ± 4.4, and 5.6 ± 5.2 units of blood were required for the salvaged, partially salvaged, and lost groups, respectively. Twenty-two patients required blood transfusion (57.9%). No patients developed wound infection with Aeromonas hydrophilia. Two patients developed donor site hematomas, and four patients developed recipient site hematomas. MLT is efficacious in congested native skin and local flaps. Some regional and free flaps can be totally or partially salvaged. However, the morbidity of MLT must be weighed against the risks of flap loss.
